Embodiment 1

[0035] A construction method for a lattice column in a subway station, comprising the following preparation steps: preparation of a lattice column 100, construction of a column pile 200 and construction of the lattice column.

[0036] Wherein the lattice column 100 includes four angle steels 101 and a plurality of panels 102, and the preparation of the lattice column includes the following steps:

[0037] a1. Arrangement of lattice columns 100: Four angle steels 101 are symmetrically arranged in pairs to form a columnar structure with a rectangular cross section. A plurality of decorative plates 102 are arranged at intervals from the top to the bottom of the columnar structure to form the main body of the lattice column. The contact area between the panel 102 on the column and the angle steel 101 is at least half of the area of ​​the panel.

[0038] a2. Welding patch 102: Weld the patch 102 along the bottom of the columnar structure to the top, and the distance between the las...

Abstract

The invention discloses a construction method for a lattice column of a subway station. The method comprises the following steps of: a, preparing the lattice column, wherein a1, arranging the latticecolumn, a2, welding a batten plate, a3, performing in-situ butt welding; b, constructing an upright column pile, wherein b1, drilling and positioning, b2, excavating to form a hole, b3, cleaning the hole and placing a steel reinforcement cage; C, constructing the lattice column, wherein c1, determining a positioning point, c2, placing the lattice column, c3, welding the lattice column and the steel reinforcement cage, c4, pouring concrete. By means of the method, the strength of the lattice column main body is guaranteed, force deformation of the lattice column main body is avoided, the installation effect of the lattice column main body is ensured, enough space for placing the lattice column and the steel reinforcement cage is provided, and the regular and horizontal arrangement of the lattice column and the reinforcement cage is ensured, the construction process of the upright column pile and the lattice column is promoted to be stable and continuous, the construction cost is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of subway construction, in particular to a construction method for a lattice column in a subway station. Background technique [0002] With the rapid development of China's economy, ground transportation can no longer meet people's needs for going out, and more and more transportation methods have emerged, such as viaducts and subways. The emergence of the subway has greatly eased the pressure on people to go out. As an important form of enclosure structure in deep foundation pit engineering, underground diaphragm wall has been widely cited in the field of rail transit engineering construction in major cities in my country in recent years. [0003] With the expansion of rail transit station space, the structural form has become more complex and the construction difficulty has gradually increased. The function of the underground diaphragm wall has gradually developed from a temporary enclosure structure to a...
