Abstract

The invention belongs to the technical field of urban rail transit engineering construction, and particularly relates to a waterproof structure at a joint between a station body and an auxiliary passage as well as a construction method. The waterproof structure at the joint between the station body and the auxiliary passage comprises a station body structure and an auxiliary passage structure which are positioned at the joint, wherein an L-shaped precast reinforced concrete beam connected with the auxiliary passage structure and the station body structure is mounted at the bottom of the auxiliary passage structure. The construction method of the waterproof structure at the joint between the station body and the auxiliary passage comprises the following steps: the station body structure isconstructed; station body tenons are constructed on the station body structure; the auxiliary passage structure is constructed and combined with the station body tenons to form a mortise and tenon structure; and the waterproof follow-up treatment is performed and the construction is completed. Through the construction of the mortise and tenon structure as well as the mounting of the L-shaped precast reinforced concrete beam, the stiffness difference and the settlement difference between the station body structure and the auxiliary passage structure can be reduced, and the water leakage phenomenon can be avoided.

Description

technical field

[0001] The invention belongs to the technical field of urban rail transit engineering construction. Specifically, the invention relates to a waterproof structure and a construction method at the interface between a main body of a station and an auxiliary channel. Background technique

[0002] With the continuous acceleration of the urbanization process in our country, the problems of urban land shortage and road traffic congestion have become more and more prominent. The development of large-capacity rapid public transportation systems with underground rails as the backbone is the main way to solve urban traffic congestion.

[0003] Although the main structure of the subway station and the auxiliary channel structure are an integral whole, each part has a sequence during construction. During construction, the main structure of the subway station is constructed in advance, and the auxiliary passage structure is set up according to the reserved opening position...
