A prefabricated load-bearing intermediate partition wall structure and construction method of a rectangular pipe jacking gallery

Abstract

A prefabricated load-bearing partition wall structure of a rectangular pipe-jacking gallery and its construction method, including pipe top embedded parts, vertical force-transmitting steel plates, pipe bottom embedded parts and walls; pipe top embedded parts include top anchor bars and pipe top Buried plate; the pipe top buried plate is connected to the jacking pipe above the wall; there are two vertical force transmission steel plates, which are connected to the bottom surface of the pipe top buried plate; the distance between the two vertical force transmission steel plates is adapted to the thickness of the wall; The pipe bottom embedded parts include the bottom anchor bar and the pipe bottom buried plate; the pipe bottom buried plate is connected to the jacking pipe under the wall; the wall bottom is provided with the wall bottom embedded part; The upper end of the wall is inserted between two vertical force-transmitting steel plates, and the embedded part at the bottom of the wall is fixedly connected with the embedded part at the bottom of the pipe. The invention solves the technical problems of difficulty in connecting the main reinforcement of the cast-in-situ load-bearing intermediate partition wall in the traditional narrow construction space, difficulty in setting up formwork on site, difficulty in vibrating, slow construction speed, poor construction environment and the need for a large number of construction workers.

Description

technical field [0001] The invention belongs to the technical field of underground engineering, in particular to a prefabricated load-bearing partition wall structure of a rectangular pipe jacking gallery and a construction method thereof. Background technique [0002] With the development of urban construction, problems encountered in the construction of urban infrastructure network pipe network system follow, such as repeated excavation of "pull links" due to pipeline expansion, expansion and maintenance, which seriously affects the traffic and safety of citizens. The use of overhead pipelines and aerial spider webs affect the city's appearance and bring great safety hazards. Today, underground pipeline safety accidents occur frequently. Only underground pipeline accidents average up to 5-6 per day, and the annual direct economic loss due to road excavation is as high as 200 billion yuan. Contradictory new models were gradually promoted. [0003] Urban comprehensive pipe...
