Construction method applied to shield tunneling machine receiving well station side wall large steel die

Abstract

The invention discloses a construction method applied to a shield tunneling machine receiving well station side wall large steel mold. The construction method comprises the following steps that a plurality of supporting frame platforms are arranged; the plurality of supporting frame platforms are supported; and a profile steel template is erected above the supporting frame platform. According to the steps, the supporting frame platform can be set up to the required height according to actual requirements, so that construction can be conveniently carried out at the position exceeding eight meters, due to the fact that the set-shaped steel formwork is integrally formed, the integrity of concrete cannot be affected, the pouring effect is ensured, and due to the fact that the set-shaped steel formwork is not a traditional wood formwork, the construction cost is reduced. And therefore, water leakage is avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a large steel formwork applied to the side wall of a shield machine receiving shaft station. Background technique [0002] In the prior art, a large shield machine with a diameter of 14m is generally used to carry out the shield section to complete the construction of the side wall of the station. However, this method will lead to a high floor height of the subway station, which is not conducive to meeting actual needs. The traditional single-side support formwork (big steel formwork) can be constructed up to eight meters high, and generally only wooden formwork can be used for construction in areas exceeding eight meters. However, wooden formwork construction has an impact on the integrity of concrete, especially with large concrete forms. The position where the steel molds meet is prone to water leakage, which will affect the construction effect. ...
