Assembly construction method of prefabricated comprehensive pipe gallery

Abstract

The invention discloses an assembly construction method of a prefabricated comprehensive pipe gallery. The method includes the steps of (1) building an enclosure structure: excavating a foundation pit, and inserting prefabricated continuous walls into two sides of the foundation pit through hoisting; (2) constructing a supporting system: oppositely supporting the continuous walls by adopting horizontal steel pipes, and enclosing purlins by adopting double-spliced section steel; (3) constructing groove section joint interconnection: pre-burying U-shaped joint bars in grooves in the two ends ofthe prefabricated continuous walls, and immediately constructing root piles for filling after the prefabricated continuous walls are mounted in place; water stop strips are arranged on the outer edgesof the two sides of the grooves in the two ends of the prefabricated continuous walls; the distance between the joints on the outer sides of the grooves in the ends of the prefabricated continuous walls are not larger than 50 mm, and cement paste is adopted for conducting close joint operation on the distance between the joints; and (4) constructing connection between bottom plates and / or top plates and the prefabricated continuous walls. The comprehensive pipe gallery is constructed by performing truss operation on a conventional concrete floor, so that the prefabrication cost and expense are greatly saved, the production speed is increased, and the production benefit is improved.

Description

technical field [0001] The invention belongs to the field of pipe galleries, in particular to an assembly construction method of a prefabricated comprehensive pipe gallery. Background technique [0002] There are many cities in our country with dense population. In order to meet the needs of people's life in the city, it is necessary to build various types of pipe corridors according to different needs. Most of the traditional underground comprehensive pipe gallery enclosure structure adopts grading excavation, steel sheet piles, bored pipe piles, etc. In terms of specific construction, most of the integrated pipe galleries are made by pouring concrete on site. The main disadvantage of this cast-in-place method is that the construction period is long, and for road sections with high traffic pressure, it will have a great impact on people's life and travel. On the other hand, from the perspective of construction technology, the cast-in-place method requires multiple types o...

Problems solved by technology

The main disadvantage of this cast-in-place method is that the construction period is long, and for road sections with high traffic pressure, it will have a great impact on people's life and travel

On the other hand, from the perspective of construction technology, the cast-in-place method requires multiple types of comprehensive construction on site, which makes the construction management on site more difficult, and the large number of personnel greatly increases the probability of accidents

Moreover, the cast-in-place method has high requirements for the construction environment, which makes it difficult to accurately control the quality of the construction, and the different construction environments of each section will easily lead to the occurrence of water seepage
