[0002] In recent years, with the large-scale introduction of underground comprehensive pipe gallery, underground comprehensive pipe gallery has become an indispensable and important infrastructure. Currently, there are centralized construction methods: open-cut and cast-in-place method, open-cut prefabricated assembly method, Shallow burial and concealed excavation method, pipe jacking method, and shield method, among which the cast-in-place method of open excavation method is to excavate the underground foundation pit on the surface under the condition of using the support structure, and construct the internal structure in the foundation pit , which has the characteristics of simplicity, convenient construction, and low engineering cost. It is suitable for the construction of pipe networks in newly-built cities, but it is not applicable in many cases, such as downtown areas; Larger-scale prefabrication plants and large-tonnage transportation and lifting equipment require higher construction technical requirements and engineering costs; the shallow buried excavation method is a construction method for underground excavation of various underground caverns that are closer to the surface , with complex conditions such as shallow burial depth, poor adaptability to stratum lithology, existence of groundwater, and complex surrounding environment. Under the conditions that the open cut method and the shield method are not suitable, the shallow burial and underground excavation method has shown great advantages, and it is flexible and versatile. roads, underground pipelines and pavement have little impact on the environment, demolition occupies a small area, and does not disturb residents. It is suitable for the reconstruction of existing cities, but it requires advanced support, which poses safety hazards, and the construction speed is very slow; the pipe jacking method is When the pipe gallery crosses various obstacles such as railways, roads, rivers or buildings, it adopts a kind of underground excavation construction method. During construction, it is supported on the back seat of the foundation pit through the force-transmitting top iron and the guide rail. The hydraulic jack presses the pipeline into the soil layer, and at the same time excavates and transports away the soil on the front of the pipe. It is suitable for soft soil or water-rich soft soil layer, without open excavation, and has little impact on the ground; less equipment, simple process, and short construction period , low cost and fast speed; it is suitable for medium-sized pipeline construction, but it is poor in adapting to pipeline change direction and difficult to correct deviation; the shield tunneling method is to use the shield to advance in the ground, and the surrounding rock is supported by the shield casing and segments to prevent accidents. The collapse in the tunnel, at the same time, excavate the soil with a cutterhead in front of the excavation face, transport it out of the hole through the excavation machine, pressurize the rear part with the propulsion cylinder, and assemble the precast concrete segments to form the structure of the tunnel. A mechanized construction method, which has the advantages of realizing automatic operation in the whole process, low construction labor intensity, and does not affect ground transportation and facilities; it is not affected by climate conditions during construction, and does not generate noise and disturbance; the buried depth of construction in soft aquifers is relatively low. Large and long tunnels often have technical and economic advantages, but their disadvantages are poor adaptability to sections with variable cross-sectional dimensions, expensive shield equipment, and uneconomical for projects with short construction sections.
