Abstract

In order to solve the problems that an existing environment settlement monitoring system cannot achieve automatic real-time monitoring and monitoring equipment is high in cost, the invention providesa settlement optical fiber string, a settlement real-time monitoring system and a using method thereof. The technical scheme of the settlement optical fiber string is as follows: the settlement optical fiber string comprises a butterfly-shaped optical fiber and an optical fiber string fixing piece, wherein the butterfly-shaped optical fiber comprises two end points at the upper part and two circular rings at the lower part, and the butterfly-shaped optical fiber is formed by encircling an optical fiber; vertical moving grooves are formed in the two sides of the front face of the optical fiberstring fixing piece respectively, horizontal positioning pieces are arranged on the vertical moving grooves respectively, and the horizontal positioning pieces vertically move along the vertical moving grooves; two positioners are arranged between the two vertical moving grooves; the butterfly-shaped optical fiber is arranged between the two vertical moving grooves, the two ends of the butterfly-shaped optical fiber penetrate through the horizontal positioning pieces respectively, and the bottoms of two circular rings of the butterfly-shaped optical fiber are in movable contact with the positioning devices respectively.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a subsidence optical fiber string, a subsidence real-time monitoring system and a use method thereof. Background technique [0002] China is currently a big country in the development and utilization of underground space in the world. The speed of urban rail transit construction ranks first in the world. The overall scale and total amount of urban underground space will soon rank first in the world. Many large-scale underground projects and infrastructure that have attracted worldwide attention are under planning and construction. middle. [0003] The construction of large-scale underground projects will inevitably have an impact on the environment of adjacent buildings (structures), such as the settlement of surrounding soil, cracking of buildings, and differential deformation of subway tunnels. In order to effectively monitor and predict environmental...
