ENGEOCOM Tunnelling Machinery

The tunnelling mechanized complex (TMC) called “Sofia” has completed the left tunneling distillation tunnel from “Shelepiha” metro station to the connecting branch of the Third interchange circuit and Kalinin-Solntsevo line. This project is initiated by the Department of Construction of Moscow as the state customer on-site. The contractor/company hired to do this work is JSC Combine ENGEOCOM.

Shield “Sofia” has covered an entire distance of 768 meters. The lines are running under Shmitovsky, an industrial area near the 1st Silica travel, and a dense residential development. Drifters have been working in the complex hydrogeological conditions, up to a maximum depth of 40 meters.

After completing the tunneling, the complex has gone into the excavation chamber congresses of the Third interchange circuit and Kalinin-Solntsevo line as next in the line for progress. While the second ring of the Moscow Metro will be built, the “Business Center” – “Peter Park” site will temporarily join with the Kalinin-Solntsevo line. Thus, temporarily, the train will go from “Rasskazovka” station to the “Petrovsky Park.”

Next TMC will be moved to the opposite end of the pit, where the construction will begin toward Kalinin-Solntsevo line. Usually after the completion of the shield, it is disassembled into parts, maintenance is carried out on the peices, and they are transported to the new launch site and collected again. On average, it takes 1.5 months to complete these steps. Metrostroiteley of Association ENGEOCOM says that they “plan to prepare Sophia for sinking down” in a new record time – just 15 days. For this purpose, a unique method of moving the shield whole will be used. Complex manoeuvres with a hand pallet truck are required to move the unit from one end of the excavation chamber to the other entirely without dismantling.

They are going to put a monolithic slab in the bottom of the shaft pit and install steel plates, with rails on which the “Sofia” will move, using a jacking system to install it onto the welded rails, starting from specially made stops and pulling it on the hand cart. So says Konstantin Tsallagov, head of the mechanization construction of Association ENGEOCOM. According to him, during the pulling, there will be mechanics on board with the “Sofia” to replace the cutting tools and to conduct the thorough inspection of all the components and assemblies that are usually inspected while the unit is disassembled for travel. When it is moving to the other end of the Metro interchange to begin it’s new work, the “skiing” movement of the Sofia will be cut off, and it will not operate until it has been inspected while in transit to the new construction site.

Application of this new experimental method allows Metrostroiteley reduce construction time and save money on the installation and dismantling of the complex, while still remaining safe for the workers to use in the tunneling process. Specialists construction workers with Association ENGEOCOM are “already used dragging to move the complex mechanics of “Sofia” and “Victoria” through station “Shelepiha.”

JSC Business Combinations ENGEOCOM acts as official contractor of the construction site of the Third interchange circuit of the Moscow Metro station from Business Center to Lower Maslovka.The line includes six stations: 5 – newly built (Lower Maslovka, Peter Park, Khodynka, Khoroshevskaya, and Shelepiha) and 1 being finished (Downtown). Construction site length is 12.76 km. The construction of these stations will be the beginning of formation of a new subway interchange circuit, which will provide a transplant from one branch to another without using the central congested hubs.

 

ENGEOCOM Working on Complete Highway Interchange Overhaul

ENGEOCOM has completed reconstruction of the highway interchange at the intersection of Ring Road and Ryazan Ave. In December Moscow’s mayor Sergei Sobyanin was on hand to open the transport tunnel to traffic for the first time since construction began. Also at the opening was the Deputy Mayor for urban highway constructionplanning, and the building of Marat Khusnullin, head of the construction department for the city of Moscow Alexey Bochkarev. Also the First Deputy head of the city’s construction department Pyotr Aksenov, as well as the president of the company ENGEOCOM, Dimitri Evseev.

Dimitri and Sergey were on hand to talk about the project. The entire reconstruction of the freeway interchange took 11 months. “In September we opened one overpass here, and in November, the second.” With the completion of the tunnel they will complete the work on all basic functions of the interchange, said Dimitri Evseev, president of ENGEOCOM. The brand new tunnel runs the length of 603 metres and will provide Congress with the counterclockwise roundabout of Lermontov Avenue on the inner side of the Moscow Ring Road. Reconstruction of the entire project, comprises a large set of measures: the construction of the overpass Moscow-Ryazan has a projected length of 178 meters, the overpass Ring – Lermontov avenue has a 168 meter long road tunnel, and 608 meters long pedestrian bridge over the Ryazan prospectus; expansion of Moscow, Ryazan and Lermontov Prospekt; and includes reconstruction of existing conventions with Moscow and relaying the underlying utilities. After the reconstruction of the facility traffic capacity will increase by 25%, which will cut down on traffic and make areas much easier to access.

The aim is to replace one of the “petals” of the traffic “clover” with a decoupling of one of the interchanges. The mayor then noted that the updated interchange will greatly improve the accessibility of the Zhulebino, Nekrasovka, and suburban Lyubertsy areas. This is the 12th upgrade in a series of upgrades at the interchange at Ring Road. It is a complex subject, which, despite all attempts to make it as easy on motorists, has cause a large inconvenience to drivers on the road.

ENGEOCOM has had workers going at maximum speed to try to make the road construction be less obtrusive to the daily lives of motorists as soon as possible. “In recent years, the builders have been working around the clock and have finished the extremely complex construction as soon as possible,” said the mayor. Clearly the intent here is to finish as soon as possible, and the government feels the push to finish this large undertaking as soon as possible.

The mayor thanked the construction workers of all of their good work and gave the command to open up the tunnel in order to let the first traffic through the new interchange.

 

New Moscow Metro Expected In 2016

Ernest Rudyak - EngeocomDeputies and General Directors of firms such as “Association” and “ENGEOCOM” visited the site of the project and discussed in great length the progress that has been achieved thus far. The building of the station, dubbed “Khoroshevskaya”, is at full swing and it is expected to be completed late in 2016.

As mentioned above, Khoroshevskaya is part of a much bigger project called the Third interchange circuit, which includes the construction of other railroad and underground stations such as “Business Center”, “Shelepiha”, “Khodynka” and “Peter Park.”

The urgency of building these transportation routes was slowed down due to the preparatory process, which took almost two years, as well as the grand scale of the project. Other setbacks included the change in building methods, which varied from closed to open in order to find the best possible way save money and finish faster. Despite these minor complications throughout the first few stages of construction, General Director for ENGEOCOM stated that close to 3.5 million rubles were saved because of these efforts. 

The difficult geological conditions present at the site of Khoroshevskaya have forced the workers to use a unique type of soil for the surface, which in turn is going to increase the rate of perforation.
