Embodiment Construction

[0038] Examples see Figure 1-12 As shown, a fast and low-risk subway station tunnel construction is the underground excavation method, including the conversion construction of the main construction channel 1 and the station tunnel 2, the conversion construction of the auxiliary construction channel 3 and the station tunnel 2, and the excavation of the station tunnel 2 Support steps. The top of the main construction channel 1 is raised to be flush with the vault of the station, and is supported by parallel access and gate-shaped steel arches 4. Auxiliary construction channel 3 is taken from station tunnel 2, which involves the station excavation construction sequence within this transition section and the support at the handover position between station tunnel 2 and auxiliary construction channel 3.

[0039] The post-excavation support of the station tunnel involves the initial support structure, temporary support structure and secondary lining structure. The initial support ...

Abstract

The invention discloses a rapid low-risk station tunnel digging method. Positions of a main construction channel and an auxiliary construction channel are determined according to a station, and station digging and supporting are conducted through four steps, namely conversion between the main construction channel and a station connection segment, digging and supporting of pilot tunnels in the station, conversion between the auxiliary construction channel and the station connection segment and digging and supporting of the station. According to the rapid low-risk station tunnel digging method, the position relation between the main construction channel and the station is adjusted, the station construction steps are adjusted, and the conversion method between the auxiliary construction channel and the station connection segment is changed, so that construction difficulty and risk of station tunnel digging are effectively lowered, the number of temporary supports is reduced, the engineering cost is lowered, and the construction period is shortened.

Description

technical field [0001] The patent of the present invention relates to a fast and low-risk subway station tunnel construction method. Background technique [0002] The rapid development of modern cities has led to more and more urban traffic congestion, so it is an inevitable requirement for many large cities and megacities to vigorously develop public transportation, especially rail transportation. For the construction of underground rail transit, in order to avoid more congestion of ground traffic during the construction process and save urban space resources, more and more subway stations are constructed by underground excavation. For example, Shapingba Station, Fengtian Road Station, and Erlang Station of the Chongqing Rail Transit Ring Line. Construction of subway stations using underground excavation method requires the use of underground excavation construction passages to enter the subway station. According to the existing design documents and construction experience...
