Steel support axial force monitoring system capable of applying prestressing force

Abstract

The invention discloses a steel support axial force monitoring system capable of applying prestressing force. The steel support axial force monitoring system capable of applying prestressing force comprises a connecting piece, an axial force meter, a supporting steel pipe body and a bracket. One end of the axial force meter is welded to an end plate of the connecting piece, and the other end of the axial force meter abuts against the bracket. A steel pipe sleeve is additionally arranged at the end of the axial force meter. One end of a flange plate of the connecting piece is directly welded to the supporting steel pipe body, and the other end of the flange plate of the connecting piece is cut into an arc and welded to the axial force meter. A cushion block is arranged between the connecting piece and the axial force meter. Hydraulic jacks are arranged on the two sides of the cushion block. By the adoption of the steel support axial force monitoring system capable of applying prestressing force, the problem that when the distance between a foundation pit supporting body and a land boundary line is too small and the elevation of a locking beam is different from that of a horizontal supporting system, negative influences on a foundation pit are caused by excessive deformation of the locking beam or an underground diaphragm wall is effectively solved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a steel support axial force monitoring system capable of applying prestress. Background technique [0002] In the field of construction engineering, the distance between the enclosure of the foundation pit and the red line of the land is too small. The remaining space limits the use of other enclosure forms such as soil nail walls and anchor rods, and also limits the design of gravity dams. width. How to solve the problem of deformation of the locking beam or the ground connection wall when the distance between the foundation pit enclosure and the red line of the site is too small and the elevation of the locking beam and the horizontal support system is different becomes a difficult problem. Contents of the invention [0003] The purpose of the present invention is to provide a steel support axial force monitoring system that can be prestressed to solve the problem tha...
