Pre-pressing sedimentation monitoring device and method of full framing

Abstract

The invention discloses a pre-pressing sedimentation monitoring device and method of full framing. The monitoring device comprises an inverted-U-shaped steel plate, a screw, a lifting rope, a hammer,a steel plate pad, and upper and lower indicating gauges fixed on the steel plate pad, a horizontal part of the inverted-U-shaped steel plate is erected on a support jacking, the inner end of the screw horizontally penetrates a threaded hole of one vertical part of the inverted-U-shaped steel plate and extends into space between two vertical parts of the inverted-U-shaped steel plate, the screw islocked on the vertical part of the inverted-U-shaped steel plate via a nut, the top end of the lifting rope is connected to the outer end of the screw, the bottom end of the lifting rope is connectedwith the hammer, the steel plate pad is positioned below the hammer, a measuring rod of the upper indicating gauge is directed to the hammer, a measuring head of the upper indicating gauge makes contact with the hammer in an extruding way, a measuring rod of the lower indicating gauge is directed to a support pedestal, and a measuring head of the lower indicating gauge makes contact with the support pedestal in the extruding way. Thus, the problems that pre-pressing deformation of the support is much influenced by weather, place and artificial factors and monitoring data is in accurate are solved effectively.

Description

technical field [0001] The invention relates to the technical field of preloading deformation monitoring of full-wall brackets, in particular to a pre-loading settlement monitoring device and monitoring method of full-wall brackets. Background technique [0002] The full hall support method is widely used in bridge construction, and support preloading is an important construction technical link. Through support preloading, the inelastic deformation of the support and the foundation can be eliminated, the elastic deformation value can be obtained, and the pre-camber of the support can be accurately set to ensure The line shape of the beam body meets the requirements, and the observation and monitoring of the support settlement is an important technical means to ensure the safety of the support and check whether the preloading of the support is qualified. The pre-compression deformation monitoring technology of full support supports plays a key role in the construction safety ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a preloading settlement monitoring device and monitoring method for full-wall support, which can effectively solve the problem that the pre-load deformation monitoring of full-wall support is greatly affected by weather, site, and human factors, and the monitoring data is inaccurate and inaccurate.
