Abstract

The present invention proposes a construction displacement monitoring device for an immersed tube tunnel and a monitoring method thereof, comprising a first box fixed on one of the pipe sections and a second box fixed on an adjacent pipe section, the first box and the second A monitoring mechanism is provided between the boxes; the monitoring mechanism includes at least two steel rods stretched and fixed between the first box body and the second box body, and a horizontal displacement monitoring device for monitoring the steel rods is provided in the first box body , the first vertical displacement monitoring device and the first longitudinal displacement monitoring device, the second vertical displacement monitoring device and the second longitudinal displacement monitoring device for monitoring the steel rod are arranged in the second box body; the present invention realizes the full The automatic monitoring of azimuth reduces the error and ensures the basic quality of pipe section construction.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a construction displacement monitoring device of an immersed tube tunnel and a monitoring method thereof. Background technique [0002] In recent years, the construction of transportation infrastructure has developed rapidly. A large number of sea-crossing bridges and passages have begun to be built. More and more sea tunnels, bridges, and artificial islands are built on complex marine soft soil foundations. The load of the underwater immersed tunnel is relatively small, mainly anti-buoyancy. Under normal circumstances, no foundation treatment is required. The tube tunnel is gradually transferred from above water to underwater. The buried depth and thickness of the soft soil foundation vary greatly, and the physical and mechanical properties are poor. Require. The foundation treatment methods for the soft soil foundation of immersed tube tunnels mostly adopt excavation and replacement met...
