Rectangular concrete piles for building side walls of pipe gallery

Abstract

The invention relates to rectangular concrete piles used for constructing a side wall of a pipe gallery. Each rectangular concrete pile comprises a pile body (1) with the rectangular cross section. The rectangular concrete piles are characterized in that a plurality of middle anchoring ribs (2) protruding out of the front end face of each pile body (1) are arranged in the middle of the pile body (1). The middle anchoring ribs protruding out of the front end faces of the pile bodies are arranged in the middles of the pile bodies, a reinforcement framework structure inside a pipe gallery bottom plate can be conveniently constructed between the middle portions of the concrete piles through the exposed anchoring ribs, and thus the pipe gallery bottom plate is constructed; meanwhile, after pouring is completed, a continuous wall and the bottom plate are connected through the exposed anchoring ribs, and the wall and the pipe gallery bottom plate can be connected more firmly; and the continuous wall manufactured from the rectangular concrete piles can be used as a foundation pit enclosure during pipe gallery construction and also can be used as the wall of the pipe gallery, and walls on the two sides of the pipe gallery do not need to be constructed additionally.

Description

technical field [0001] The invention belongs to the technical field of municipal underground engineering, and in particular relates to a rectangular concrete pile used for constructing the side wall of a pipe gallery. The rectangular concrete pile can be a solid pile or a centrifugal pile. Background technique [0002] my country's urban municipal public utilities are constructed and managed by different units. Due to the different construction time, there is no unified planning and comprehensive utilization of urban underground space. The construction of underground pipe networks mostly adopts the traditional direct-buried municipal pipe network construction method. Various municipal pipes are mostly buried directly in the soil layer according to their respective systems, which is inconvenient for maintenance and easily damaged, and the supply capacity is often disturbed. Due to the different buried depths of various pipelines, it is easy to cause conflicts, and urban roads...

AI Technical Summary

Problems solved by technology

The foundation pit enclosure is generally formed by connecting rigid sheet piles or bored piles, but due to its poor strength and waterproof performance, and the lack of suitable connection points for better fixing with the bottom plate and top wall of the pipe gallery, it is impossible to be used as a foundation pit enclosure. Part of the side wall of the pipe gallery, the main body of the entire pipe gallery must be poured on site in the enclosed foundation pit (rebar binding, formwork support, concrete pouring and maintenance, etc.). Disadvantages such as long period, high project cost, inconvenient application of advanced construction technology, etc.

The second is the overall prefabricated square culvert underground pipe gallery, which has large volume and weight, which brings disadvantages such as high requirements for manufacturing equipment, difficult lifting, large transportation volume, and high transportation costs, and is prone to local settlement and water leakage of the pipe gallery

Another is to use the underground diaphragm wall as the enclosure of the foundation pit. Although this kind of underground diaphragm wall can be used as the side wall of the pipe gallery in theory, in the actual construction process, there is no suitable structure for better matching with the bottom plate and top wall of the pipe gallery. Fixed connection points and stress points, so it is not convenient to pour between two adjacent continuous walls to form the top and bottom of the pipe gallery. In addition, it is necessary to consider whether the connection between the continuous wall and the top and bottom of the pipe gallery is firm and other technologies Therefore, there has never been an engineering precedent in which the underground diaphragm wall used as foundation pit enclosure is directly used as the side wall of the pipe gallery in practice
