Abstract

The invention relates to the technical field of subway engineering, and discloses a structure of a station side wall formed by combining omega-shaped inserting plates with convex pilasters and a construction method, the structure comprises prefabricated pilasters, omega-shaped prefabricated inserting plates, a wall back pouring layer, pilaster brackets, prefabricated middle columns, prefabricated middle (top) longitudinal beams, laminated middle (top) plates and steel bar trusses, the omega-shaped prefabricated inserting plate is fixedly connected with the prefabricated pilaster through bolts, a steel bar truss is arranged on the omega-shaped prefabricated inserting plate, the wall back pouring layer is located between the foundation pit side wall and the omega-shaped prefabricated inserting plate, the omega-shaped prefabricated inserting plate is provided with the steel bar truss, on-site steel bar binding is directly and effectively avoided, and the construction efficiency is improved. The structure construction quality is improved, and the construction efficiency is improved; by means of the prefabricated pilaster, the pilaster bracket, the omega-shaped prefabricated inserting plate and other components, formwork-free and scaffold-free construction on a construction site can be achieved, the efficiency is improved, and meanwhile the problems that formwork erecting is difficult, and the risk is large are solved; the method is suitable for assembly type subway stations and similar projects, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of subway construction, in particular to a structure and a construction method for forming a station side wall by combining an omega-shaped insert plate with a convex pilaster. Background technique [0002] At present, the traditional cast-in-place construction of subway stations and sections generally has problems such as high energy consumption, high pollution and low efficiency, which are not in line with the country's current development requirements for new urbanization, industrialization, and informatization. [0003] For the construction of the side wall structure of the subway station, the full cast-in-place method or the prefabricated method is generally adopted. The full cast-in-place method is mainly based on on-site manual and wet operations. The degree of mechanization is low, and the quality is difficult to effectively control. The scaffolding scheme is mainly used, the construction work space ...

Problems solved by technology

[0002] At present, the traditional cast-in-place method for construction of subway stations and sections generally has problems such as high energy consumption, high pollution and low efficiency, which are not suitable for the current development requirements of the country's new urbanization, industrialization and informatization

[0003] For the construction of the side wall structure of subway stations, the full cast-in-place method or assembly method is generally adopted. The full-cast-in-place method is mainly based on on-site manual and wet operations, with a low degree of mechanization and difficult to effectively control the quality. The scaffolding scheme is mainly used, the construction space is narrow, the construction efficiency is low, the construction risk is high, and the overall comprehensive benefit of construction and construction is low. The proposal of the subway prefabricated construction model effectively solves the above problems, but it is limited to the beginning of the research on the prefabricated structure of the subway. As for the prefabricated structure of the side wall of the subway station, the Changchun Metro related projects that have been completed and similar projects under study generally adopt the shield segment assembly that divides the components into blocks and then assembles them into rings. Design thinking, this assembly method has disadvantages such as large component size, difficulty in transportation and storage, strict lifting and installation requirements, low construction efficiency and high project cost, so a structure of similar Ω-shaped inserts combined with convex pilasters to form the side wall of the station is proposed and construction method
