Zhd approaches to the Kerch bridge. Railway approach project will have to be adjusted due to soils

On April 19, at the 21st international exhibition on transportation, transport and logistics "TransRussia", the Ministry of Transport of Crimea presented a video on the construction of railway approaches to the bridge across the Kerch Strait. The visualization video shows a new railway junction as the designers see it, a new railway station with an underpass, an overpass over the road to Arshintsevo, a bridge over the Melek-Chesme River and other structures.

The section of the new railway line will run along the North-Eastern part of the peninsula from the Kerch Strait to the Bagerovo station. The approaches being designed are a double-track railway line with a length of 18 km. The deployed length of the laid tracks is 47 km.

An interesting observation. In the Lenproject video, the M62 diesel locomotive is shown in a modification from the BZHRK - DM62 (railway missile system "Molodets"). The carts are jawless (although the springs were “forgotten” during visualization), block buffer lights (rectangles) and, most importantly, a communication and control panel (a box under serial number) ... so the diesel locomotive is combat and this is no coincidence. An extra reminder: we are peaceful people, but our armored train is on the siding.

The construction of a new park of the Kerch-South station, located 3 km from the transport crossing, is envisaged. At the existing Kerch station, it is planned to build a base for fire and recovery trains, which is necessary to provide the projected and existing railway infrastructure.

The new park of Kerch-Yuzhnaya station will receive, depart, and pass freight passenger and suburban trains, embarkation and disembarkation of passengers. For the safety of passengers, the construction of an underground pedestrian tunnel is envisaged.

The project provides for the reconstruction of engineering communications falling into the construction zone. For the intersection at different levels of the existing railway line Kerch-Arshintsevo and the projected haul Kerch-Yuzhnaya - Bagerovo station, a single-track railway overpass was designed for 14 km of the Kerch-Arshintsevo line.

Due to the difficult terrain on the site, it was necessary to provide a large number artificial structures.

Employees of CJSC Lenpromtransproekt designed a technically complex modern artificial structure - a double-track railway tunnel with a length of 1 km, designed for seismic activity of 9 points.

A bridge on a curve with a radius of 1,500 meters is provided across the right tributary of the Melek-Chesme River.

For the passage of agricultural machinery and the passage of cattle, it is planned to build a double-track single-span overpass 44 meters long.

In the area of the village of Bagerovo, it is planned to build a railway overpass over the projected road bypass of the city of Kerch.

It is planned to reconstruct the Bagerovo station, which will allow handling freight trains of all directions, as well as serving passenger and commuter trains.

CJSC "Lenpromtransproekt" performs engineering surveys and development of design estimates for the construction of railway approaches on the territory of the Republic of Crimea to the transport crossing through the Kerch Strait.

Location: Republic of Crimea, Leninsky district

The purpose of the design is to ensure the connection of the existing railway network Crimean peninsula with a bridge across the Kerch Strait. The section of the new railway line will run along the northeastern part of the peninsula, from the Kerch Strait to the Bagerovo station. The approaches being designed are a double-track railway line with a length of 17 kilometers with the possibility of subsequent electrification.

An excerpt from the Federal Target Program for the Development of Crimea:

As Kommersant found out, the construction of railway approaches to the Crimean bridge ran into a problem, the project will have to be adjusted. One of the reasons is soil problems. This, according to preliminary estimates, will require the allocation of up to 3 billion rubles. from the budget.

As sources told Kommersant, during the implementation of the project for the construction of railway approaches to the Kerch bridge from the Crimea, problems arose with the soil used for the construction of the subgrade. The project was developed by the St. Petersburg Lenpromtransproekt commissioned by the Federal State Unitary Enterprise Crimean Railway (KZhD), which was directly subordinate to the region, but, one of Kommersant’s interlocutors emphasizes, the document turned out to be “poorly prepared.” As a result, Roszheldor turned to the general contractor Stroygazmontazh (SGM) with a proposal to make an adjustment. The maximum cost of work to solve this problem reaches 2.9 billion rubles, the real amount and sources of funding "will be known later."

The Ministry of Transport confirmed to Kommersant that the need for repeated engineering surveys was caused by poor-quality performance of the work of Lenpromtransproekt JSC, in connection with which Roszheldor sent an appeal to the prosecutor's office. Repeated surveys, the Ministry of Transport added, will be carried out by Stroygazmontazh.

Lenpromtransproekt clarifies that the fault lies with the subcontractor. Rostislav Shkurko, CEO of the company, reminded Kommersant that the company received a positive conclusion from Glavgosexpertiza in June 2016, “all work was done with high quality, as evidenced by the positive conclusions both on the technical and price audit, and on the technical and cost estimate of the project.” Geological engineering surveys were subcontracted by Krymsetenergoproekt LLC, both on the railway approach and on the road, says the top manager. Based on the received drilling materials and laboratory tests, design solutions were developed, the construction time in accordance with the construction organization project was 29.7 months, however, the contract with Stroygazmontazh was concluded only in April 2017, notes Mr. Shkurko. At the beginning of construction, he explains, according to the results of control drilling, it was revealed that the actual properties of the soil differ from the survey materials carried out by Krymsetenergoproekt LLC and used for design. The soil is partially unsuitable for the construction of an embankment, it can be used by stabilization, which requires additional time, says the top manager. “Given the importance of the facility, social significance and construction time, it was decided to replace the soil, which requires at least 500 million rubles,” says Rostislav Shkurko, adding that there are no building materials in Crimea now and the question is being decided where to bring the soil from.

“As part of the fulfillment of warranty obligations, Lenpromtransproekt applied to Roszheldor in May and received permission to re-conduct geological surveys at its own expense. Today, geology has been re-done, all studies have been carried out, and a second Glavgosekpertiza should take place in the near future, ”the top manager notes. According to him, Roszheldor, KZhD and Lenpromtransproekt submitted materials to the Prosecutor General's Office, and the company also filed a lawsuit against Krymsetenergoproekt LLC.

2.9 billion rubles are connected not only with an error in the project on soils, additional funds are required in connection with changes in the project for electrification, signaling, transport security, etc., Mr. Shkurko concludes.

In "Stroygazmontazh" they say that at the same time, construction and installation work does not stop. “The company has developed and is implementing a mechanism of action that involves adjusting certain sections of the existing project, which will not affect the overall completion time for the project and the launch of traffic on the railway approaches to the bridge on time,” the company stressed, assuring that the additional amount of work will not will affect the timing of the construction of approaches to the bridge.

The head of Infoline-Analytics, Mikhail Burmistrov, notes that the choice of a subcontractor for earthworks was potentially small due to the limited number of companies operating in the Crimea. The company's mistake led not only to the risks of Lenpromtransproekt losing the contract, but also to possible legal costs, the expert believes. Taking into account the fact that it was decided to bring soil, the amount of 2.9 billion rubles. looks absolutely adequate, believes Mr. Burmistrov. According to him, if the situation drags on for another couple of months, there is a risk of delays. Perhaps, it is in connection with this that Roszheldor proposes to adjust the draft SGP on its own, Mikhail Burmistrov notes. If the situation drags on for another couple of months, there is a risk of shifting the deadlines, which is not beneficial to anyone, the expert emphasizes.

Representative of Deputy Prime Minister Dmitry Kozak (in charge of Crimea) Ilya Dzhus noted that Mr. Kozak discussed the issue of the need to adjust project documentation on approaches, including at a meeting last week in Simferopol. Mr. Juice confirmed that there were serious complaints about the quality of the project documentation, and did not rule out that the designer's work on this project could arouse the interest of law enforcement agencies.

Adjustment of the project will not affect the deadlines for the delivery of railway approaches, the representative of the Deputy Prime Minister emphasized.

Final decisions on a possible adjustment of the cost of the construction of approaches can be made only after the finalization of the project documentation, Ilya Dzhus concluded. This will not affect the cost and timing of the delivery of the Crimean bridge itself.

A Kommersant source in KZhD said that they are not engaged in the construction of approaches to the Crimean bridge, but will take on their balance sheet the finished railway when it is built. “Therefore, these questions are not for the KZD. There is a customer - Stroygazmontazh. There is a designer - Lenpromtransproekt. Whether the project will rise in price, whether the deadlines for its implementation will be shifted - these are questions for them, ”said the interlocutor of Kommersant. The press service of the KZD “Kommersant” confirmed that the project documentation for the construction of railway approaches to the transport crossing through the Kerch Strait, provided by Lenpromtransproekt JSC, has a number of shortcomings and errors. FSUE "KZD" does not have information regarding the timing and changes in the cost of the construction of approaches. In the Southern Transport Prosecutor's Office, Kommersant has not yet received a response to an official request.

WITH transport system mainland Russia through Vyshesteblievskaya station. The double-track approach from the side of the Taman Peninsula is formed from factory-made sleeper-rail lashes up to 800 m long. They are laid in a line on a prepared elastic surface (ballast layer of sand and crushed stone) and interconnected. This is reported by the Infocenter "". “The railway line to the Crimea is being built in a seamless way. This is the so-called velvet track made of rail lashes. They are several times longer than the standard 25-meter rail. The longer the rails, the fewer joints between them, passing through which the wheels of the trains characteristically knock. On the velvet track, trains run smoothly and almost without noise. Such a road is more reliable, more durable and more convenient to operate,” said Vitaly BESHLIU, head of the design department of FKU Rostransmodernizatsiya. The project of modern railway infrastructure on Taman Peninsula- this is a steel highway with a linear length of almost 40 km - is being implemented as part of the development of transport and logistics capacities of the Azov-Black Sea basin, the creation of a new deep-sea port. In 2014, the project also included a branch to the Crimean bridge. Read: Construction and installation work is being carried out simultaneously along the entire length of the route. On this moment along the main course, the construction of the subgrade and embankment was completed in full, the construction of the superstructure of the track is being completed. 130 turnouts were assembled, more than 2200 reinforced concrete poles and metal racks of the contact network were installed. The degree of readiness of artificial structures, including bridges and overpasses, is from 60 to 100%. The facility employs more than 1,000 engineers and workers and 110 pieces of equipment. “Simultaneously with the road, the Taman-Passenger station is being built, through which trains of short-range and long distance both towards Crimea and towards Krasnodar Territory and other regions. Residents of villages and settlements on the Taman Peninsula will have a more convenient way to travel anywhere in the country. To this end, a complex of buildings is being built, including a railway station for 50 people, passenger and baggage platforms, receiving and departure tracks and other facilities,” said Anatoly VERESCHAKA, Deputy Head of Department, Project Manager at FKU Rostransmodernizatsiya. On the other side, from the Crimean side, railway workers lead a double-track approach road 18 km long to the bridge across the Kerch Strait. It includes 27 artificial structures, including a bridge and 5 viaducts. 38 new buildings and the Yuzhnaya station are being built in the complex with the highway. The approach will connect the bridge with the railroads on the peninsula, which connect rail communications with Dzhankoy, Feodosia, Simferopol and other cities. Read: “The approaches from the Crimea and Kuban will be put into operation together with the railway part of the Crimean bridge in 2019. Its capacity will be 47 pairs of passenger and freight trains per day in both directions,” said Leonid RYZHENKIN, Deputy General Director for Infrastructure Projects at STROYGAZMONTAZH. The Crimean Railways, which will put the bridge into operation in December 2019, has already prepared a preliminary train schedule for 2020. It is assumed that in the first year of operation between the Crimean peninsula and continental Russia, 29 pairs of trains per day will run, including 15 passenger, 10 freight and 4 commuter trains.

The KerchINFO team has prepared an incredible photo and video report from the auto-approaches to the Crimean bridge and the flyover on Solnechny. We offer to fly to a height of more than 100 meters.

This is a view towards the Bagerovo station and the Tavrida highway, behind the Kerch Strait and the Crimean bridge across it -

A four-lane auto-approach route passes under the overpass under construction on the Highway of the Heroes of Stalingrad. The image shows a temporary intersection of the highway and the approach at the same level. This intersection will be closed. As the overpass will soon be completed and opened, so it (the intersection) will be liquidated.
To the left of the road approach, under the same overpass, there will be a double-track electrified railway line "Taman - Kerch-South - Bagerovo".

New terminal railway station Kerch-South, with an additional second Kerch railway station, will be built here -

The diagram also shows the drawings of the park of the new station -

There is also such a scheme -

The new Kerch station will have two passenger platforms and a fleet of five receiving and departing tracks, of which two tracks will be purely transit tracks, and three tracks will be available for passengers of passenger and suburban trains.
Of course, the station will be brought highway, with auto-approach decoupling. It is quite possible that the trolleybus will fail.
For Kerch, three passenger platforms are more than enough.

Left - new park station Kerch-Yuzhnaya with a new station, to the right - Crimean bridge -

Further, behind the new park of Kerch-Yuzhnaya, if you go from the Crimean bridge, there are also overpasses for crossing railway lines with the Taurida auto-approach and a railway tunnel. We have already seen them in the topic.

In a year this place will change a lot. In the Russian Crimea, they are already accustomed to positive large-scale changes. The Crimean federal budget will not be milked forever. Russia has already built and will complete the construction of the main significant facilities. The point of Crimea is to use them wisely for the benefit of the entire vast country. With their help, to develop a resort service of the proper level, so that none of the compatriots would be drawn to all sorts of Egypt and Turkey. So that all Russians can have a great rest in their Crimea and, having gained strength, build their huge Power further.

The upper structure of the railway track to the Crimean bridge from Taman is 80% ready. This was reported by the information center "Crimean Bridge".

“More than 80% of the upper structure of the railway track is ready, which will connect the Crimean bridge with the transport system of mainland Russia through the Vyshestebliyevskaya station. The double-track approach from the side of the Taman Peninsula is formed from factory-made sleeper-rail lashes up to 800 m long,” the information center said.

Railway workers lay sleepers and rails in a line on a prepared elastic surface (ballast layer of sand and crushed stone) and connect them together. “The railway line to the Crimea is being built in a seamless way.
