Immersed tunnel construction displacement monitoring device and monitoring method thereof

Abstract

The invention provides an immersed tunnel construction displacement monitoring device and a monitoring method thereof. The device comprises a first box body fixed on one pipe section and a second boxbody fixed on the adjacent pipe section, and a monitoring mechanism is arranged between the first box body and the second box body; the monitoring mechanism comprises at least two steel rods which arefixed between the first box body and the second box body in a stretching way, a horizontal displacement monitoring device, a first vertical displacement monitoring device and a first longitudinal displacement monitoring device which are used for monitoring the steel rods are arranged in the first box body, and a second vertical displacement monitoring device and a second longitudinal displacementmonitoring device which are used for monitoring the steel rods are arranged in the second box body; and the immersed tunnel construction displacement monitoring device and the monitoring method thereof realizes the omnibearing automatic monitoring of an immersed tunnel, reduces the error and ensures the foundation quality of the tube 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...
