Shield tail deformation monitoring device and construction method thereof

Abstract

The invention relates to a shield tail deformation monitoring device and a construction method thereof. The monitoring device is installed in a gap between the inner wall of a shield tail and a duct piece and comprises springs arranged at intervals, and one end of each spring being fixed to the inner wall of the shield tail; a tension sensor, fixed to the other end of the spring and installed on the inner wall of the shield tail, and a set distance existing between the tension sensor and the end, fixed to the inner wall of the shield tail, of the spring, so that the spring extends, and the tension sensor correspondingly obtains an initial tension value. When the shield tail deforms, the spring correspondingly extends or contracts, and then the change amount of the tension of the spring ismeasured through the tension sensor so as to calculate the deformation amount of the shield tail. The problem that deformation of the shield tail of the shield tunneling machine is difficult to monitor is effectively solved, the deformation of the shield tail of the shield tunneling machine can be continuously reflected in real time, a pair of shield tails can be repaired in time, and therefore the construction efficiency is improved, and the construction quality is guaranteed.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a shield tail deformation monitoring device and a construction method thereof. Background technique [0002] At present, with the development of society, more and more construction projects need to be carried out underground, thus greatly increasing the utilization rate of shield tunneling. The tail of the shield is prone to deformation. If the deformation is too large, it may cause problems such as the inability to assemble the segments, and may even fail to continue normal construction, which seriously affects the construction quality and construction progress. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a shield tail deformation monitoring device and its construction method, solve the problem of difficulty in monitoring the deformation at the shield tail of the shield machine, and can respon...
