Abstract

The invention discloses a monitoring method for vertical displacement of a bridge type shield rail. The monitoring method for the vertical displacement of the bridge type shield rail comprises a laserrangefinder, a laser measuring board, a rail, a shield machine and an information processing terminal. The monitoring method for the vertical displacement of the bridge type shield rail can avoid theinfluence of horizontal displacement, measure the vertical offset of the rail in real time and accurately during the construction of the bridge type shield machine, feed back to an operator of the shield machine, and then adjust the shield machine according to data. The vertical displacement can further be used as a basis for whether the rail needs to be repaired or not after construction.

Description

technical field [0001] The invention relates to a method for monitoring the vertical displacement of a steel rail when a bridge-type shield machine is operated, and belongs to the technical field of engineering measurement. Background technique [0002] Nowadays, urban vehicles are growing rapidly, and large and medium-sized cities across the country are undergoing comprehensive planning and renovation, including jacking frame bridges under the existing railway lines to dredge traffic. However, during the construction of railway frame bridges, due to the influence of the shield structure itself and construction errors, the subgrade of the line in the disturbed part of the construction will be deformed to varying degrees, and the rails will have a certain amount of offset, which will affect the smooth operation of the train. Sexuality, accelerated wheels and rail wear, serious and even the risk of train derailment. At the same time, if the specific displacement of the rail c...
