The invention discloses a construction method of a subway station invaded by an existing underground channel. The construction method of the subway station invaded by the existing underground channelcomprises the following steps that S1, an existing underground channel structure is reinforced in advance; S2, existing underground channel structures are removed by adopting a rope sawing cutting method; S3, existing underground channel reconstruction is fenced off; S4, enclosing piles in the existing underground channel invading the station structural range are constructed; and S5, the existingunderground channel is recovered. The construction method of the subway station invaded by the existing underground channel is applied to a subway station underground main body invading existing structure construction, the construction method of reinforcing the underground channel structure in advance and rope sawing cutting existing buildings is adopted, structural stability of the existing channel and personnel safety in construction period are fully guaranteed, the construction speed can be accelerated by adopting the rope sawing cutting method, and the construction period is shortened; theexisting channel structure is not damaged on a large scale, and the using function of the existing channel is ensured in the construction period; and the problems that the existing channel cannot beremoved integrally, and removal objects cannot be transported in bulk are solved, time is shortened, and machinery and labor are saved.
Description
Technical field [0001] The invention belongs to the technical field of subway station construction, and in particular relates to a subway station construction method in which an existing underground passage invades. Background technique [0002] In recent years, with the continuous improvement of my country's economic level and the continuous growth of social demand, the traditional urban transportation vehicles in the past can no longer meet people's travel requirements, while urban rail transit is affordable, convenient, safe, comfortable, and fast. The advantages of low pollution and low pollution have attracted more and more attention. my country’s urban rail transit projects have developed rapidly this year. However, because subway construction is basically located in urban areas and often intersects with existing buildings, complex underground structures directly affect the safety, quality, progress, and benefits of subway construction. The existing passages of underground ...
