Subway station structure built by pipe jacking process and construction method thereof

Abstract

The invention belongs to the technical field of underground engineering structures, specifically relates to a subway station structure built by a pipe jacking process and a construction method thereof, and mainly aims to provide a subway station structure built by a pipe jacking process and a construction method thereof, which effectively meet various requirements for green construction in modernstructure construction. The invention provides the subway station structure built by the pipe jacking process. The subway station structure mainly comprises a plurality of pipe jacking tunnels parallel to each other and produced by a pipe jacking machine; a subway station hall layer middle plate is arranged in each pipe jacking tunnel; a track jacking air duct is arranged at the lower part of eachsubway station hall layer middle plate; a station and a traveling track are arranged at the bottom of each pipe jacking tunnel; adjacent pipe jacking tunnels are communicated through a channel top structure and a channel bottom structure respectively. According to the subway station structure built by the pipe jacking process, mechanical underground excavation construction technology process is effectively realized in the subway station construction process.

[0002] The 21st century is the century of great development of underground space. An important direction for the development and utilization of underground space is the direction of underground rail transit. With the rapid expansion of cities, cities are becoming more and more congested. Urban rail transit is to alleviate urban traffic congestion and extend urban influence. important means; at present, subway construction projects are in full swing in major large and medium-sized cities. As a solution to the "long-term pain" problem of traffic congestion, subway construction is inevitably faced with thorny "short-term pain" problems; however At present, the construction of the subway section is mainly based on the mechanized underground excavation construction using the shield machine. This construction method does not need to open up the ground and has little impact on the ground. However, the subway station lacks a good underground excavation construction method, and often relies on the open excavation method. Carry out open-cut construction; the use of open-cut construction has brought serious negative impacts on ground traffic and the urban environment, and is the pain point of urban subway construction; therefore, how to realize the mechanized underground excavation construction of subway stations through the innovation of equipment and construction methods It is of great practical significance to effectively reduce the adverse impact of subway station construction on urban traffic and the ground environment, to meet the needs of safe and efficient production, and to meet the environmental needs of green environmental protection.
