Problems solved by technology

The construction of the brick membrane requires more labor and materials, and the work efficiency is low and cannot meet the requirements of rush projects. At the same time, when the concrete is poured and vibrated, due to the downward fluidity of the concrete and the vibration force of the vibrating rod, the brick membrane is also easy to be damaged. Outward expansion deformation damage will increase the loss of concrete
[0003] Therefore, there are above-mentioned inconveniences and problems in the known brick tire membrane construction mode

Abstract

The invention provides a construction method of an underground mass concrete steel formwork. The construction method of the underground mass concrete steel formwork is characterized by comprising the following steps that a, a plurality of steel formworks and fixing parts are customized; b, the multiple fixing parts are pre-buried, and the fixing parts are vertically pre-buried in an original soil layer; c, the steel formworks are connected and spliced, the spliced seams are fully welded, and the steel formworks are fixed to a plain concrete cushion layer through the fixing parts; and d, the steel formworks are checked and accepted after being fixed. The construction method of the underground mass concrete steel formwork has the advantages that the steel formwork is simple in structure, convenient to manufacture, good in reinforcing effect and easy and convenient to operate, the steel formwork can be repeatedly used, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a construction method for pouring concrete, in particular to a construction method for underground large-volume concrete steel formwork. Background technique [0002] The construction project basically uses the traditional brick membrane construction method in the foundation construction stage. The construction of the brick membrane requires more labor and materials, and the work efficiency is low and cannot meet the requirements of rush projects. At the same time, when the concrete is poured and vibrated, due to the downward fluidity of the concrete and the vibration force of the vibrating rod, the brick membrane is also easy to be damaged. Outward expansion deformation damage will increase the loss of concrete. [0003] Therefore there are above-mentioned various inconveniences and problems in known brick tire film construction mode. Contents of the invention [0004] The purpose of the present invention is to propose a s...
