Abstract

The invention provides a measuring device and a measuring method for layering horizontal displacement of a base pit enclosing structure. The measuring device comprises a relative displacement measuring device and an absolute displacement measuring device; the relative displacement device comprises a first wire-fixing device fixedly mounted on the side face of a first enclosing structure, a first laser distance measuring sensor mounted on the first wire-fixing device, and a displacement refractive sheet mounted on a second enclosing structure; the absolute displacement measuring device comprises a second wire-fixing device mounted on the top face of the first enclosing structure, a second laser distance measuring sensor mounted on the second wire-fixing device and a reference refractive sheet outside a base pit; the first and second wire-fixing devices comprise a base ball socket internally provided with a ball socket, and a ball head rotor in spherical match with the ball socket respectively; the ball head rotors are fixedly connected with the first and second laser distance measuring sensors; and locking devices are arranged between the ball socket and the ball head rotors. The measuring device is simple in structure, is simple and fast in measuring process and is high in measuring precision.

Description

technical field [0001] The invention relates to a device and a method for measuring horizontal displacement at different depths of an enclosure structure of foundation pit engineering. In particular, it relates to a measuring device and method for measuring the horizontal displacement of the foundation pit enclosure structure in layers when both sides of the foundation pit enclosure structure are substantially parallel. Background technique [0002] During the construction of foundation pit engineering, the horizontal displacement at different depths of the foundation pit enclosure structure is the main evaluation index of the safety of foundation pit engineering, so it is the main monitoring item in the process of foundation pit construction. [0003] The horizontal displacement at different depths of the foundation pit enclosure structure is generally measured with an inclinometer after the inclinometer tube is buried in the enclosure structure. The burial of the inclinom...
