Counterforce frame mounting method

Abstract

The invention discloses a counterforce frame mounting method, and relates to the technical field of building construction. The counterforce frame mounting method includes the following steps that a counterforce frame is pre-positioned, specifically, the site mounting position is measured according to a design scheme, and the mounting position of the counterforce frame is pre-positioned; the counterforce frame is mounted, specifically, a lower part, a left connecting part, a right connecting part and an upper part are sequentially mounted and fixed, and power devices are mounted on the corresponding position of a first annular section; the counterforce frame is subjected to re-check positioning, specifically, the front-rear position, the horizontal position and the vertical position of thecounterforce frame are rechecked and adjusted; the counterforce frame is fixed, specifically, the lower part and a steel plate base are welded and fixed, and a supporting part is welded and fixed between the counterforce frame and the steel plate base; and the power devices are debugged, specifically, the extending and retraction length and pressure of each set of power device are adjusted to enable the power devices to abut against corresponding negative ring segments. Through the adjusting effect of the power devices arranged on the upper part, the negative ring segments bear force evenly, and normal use of the negative ring segments and shield safe production and construction are ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for installing a reaction force frame. Background technique [0002] The reaction force frame is an important component of the shield machine's initiation. The shield machine's initial propulsion transmits the thrust to the reaction force frame through the negative ring segment. The reaction force is transmitted to the shield machine, so that the shield machine moves forward. [0003] The traditional installation method of the reaction frame is difficult to ensure that the contact surface of the reaction frame and the negative ring segment is close and compact. Even if it is installed in place as required, it is difficult to avoid the deformation of the negative ring segment after it is assembled into a ring and subjected to force, and The elastic and inelastic deformation of the reaction frame under the force causes a gap between the force surface of the ...

AI Technical Summary

Problems solved by technology

[0003] The traditional installation method of the reaction force frame is difficult to ensure that the contact surface between the reaction force frame and the negative ring segments is close and dense. The elastic and non-elastic deformation of the reaction force frame under the force causes a gap between the force surface of the negative ring segment and the contact surface of the reaction force frame, resulting in uneven stress, cracks, damage, or even failure of the negative ring segment. Normal use and guarantee safe production and construction of shield tunneling
