Bridge pier foundation underwater detection device and using method thereof

Abstract

The invention relates to the technical field of underwater detection, and particularly relates to a bridge pier foundation underwater detection device and a using method thereof. The bridge pier foundation underwater detection device comprises towing ships, wherein the inner sides of the two towing ships are movably connected with a suspension assembly, water pumps are fixedly installed on the upper sides of the towing ships, the input ends of the water pumps are fixedly connected with water inlet pipes, first wire rollers and second wire rollers are fixedly installed on the upper surfaces of the towing ships, and second motors are fixedly installed on one sides of the first wire rollers and the second wire rollers respectively. When the water pumps work at the same time, the whole suspension assembly vertically descends to perform vertical photographing detection, when the water pump on one side works, a hollow floating box on one side sinks firstly, then water flow gradually spreads to the hollow floating box on the other side, so that a connecting rope fixedly connected between two fixing plates is inclined, then a detection assembly performs inclined photographing detection along the connecting rope, the photographing range is increased, and photographing detection is performed.

Description

technical field [0001] The invention relates to the technical field of underwater detection, in particular to an underwater detection device for bridge pier foundations and a method for using the same. Background technique [0002] The bridge pier is a sub-structure that supports the bridge span structure and transmits the dead load and vehicle live load to the foundation. The bridge abutment is set on both sides of the bridge, and the bridge pier is between the two bridge abutments; [0003] Bridge pier foundations may be worn after long-term water erosion, so regular inspections of bridge pier foundations are required, but it is very troublesome for staff to regularly go underwater for inspections, so an underwater inspection device is proposed to inspect bridge piers The real-time status of the foundation, and the shooting and detection of bridge piers that are invisible to the staff, and at the same time prevent the bridge from tilting and collapsing due to damage to bri...
