Construction method of subway side wall tripod single-side aluminum mold

Abstract

The invention discloses a construction method of a subway side wall tripod single-side aluminum mold, which comprises the following steps of: 1, constructing a bottom plate (4) and a reverse side wall (5), and installing a haunch angle template (1), so that a haunch angle structure (8) is formed between the reverse side wall (5) and the bottom plate (4); 2, binding reinforcing steel bars of a subway side wall (7); 3, assembling a formwork support system; 4, adjusting and reinforcing the formwork support system; 5, pouring the subway side wall (7) with concrete; 6, after pouring of the subway side wall (7) reaches the design strength, removing the formwork support system, and removing the formwork support system to the next construction section through universal wheels; and 7, repeating the step 1 to the step 6 until construction of the whole subway side wall (7) is completed. By means of the combined structure of the aluminum formworks and the triangular formwork supports of the aluminum formworks, the side wall formworks can be stably installed conveniently, and the moving flexibility and using convenience of the formwork support system are improved.

Description

technical field [0001] The invention relates to a construction method for a side formwork of a wall body, in particular to a construction method for a single-side aluminum formwork of a tripod on a side wall of a subway. Background technique [0002] The subway is a fast, large-capacity, electric traction rail transit, and it is the development direction of the construction of transportation facilities in various cities. Most of the subways run underground. During the construction of underground structures, ground connection walls and internal supports are usually used as enclosure structures after excavation of foundation pits to ensure the safety of foundation pits. However, due to the setting of the enclosure structure, the formwork of the side wall of the structure cannot be reinforced by the traditional pull-screw method during installation, which affects the installation operation and stability of the formwork of the side wall, and further affects the quality of concre...

Problems solved by technology

However, due to the setting of the enclosure structure, the formwork of the side wall of the structure cannot be reinforced by the traditional pull-screw method during installation, which affects the installation operation and stability of the formwork of the side wall, and further affects the quality of concrete pouring of the side wall

At the same time, because the side wall formwork of the prior art is a steel formwork, which is heavy, it is extremely inconvenient to move and assemble, and it cannot be lifted and moved by large-scale equipment in the limited construction space of the foundation pit. It takes time and effort to disassemble and separate the formwork and its brackets, hoist them to the next construction section and then assemble them, which seriously affects the construction progress
