An intelligent U-shaped base and method for dealing with scour pits of bridge pile foundations

Abstract

The invention discloses an intelligent U-shaped base and a method for processing a bridge pile foundation scour pit, comprising a U-shaped base main body, an equipment cabin, a water tank and a cement slurry cabin are arranged inside the U-shaped base main body, and an intelligent measurement and control is arranged in the equipment cabin Terminals, batteries and cables, the cement slurry grouting port and the grouting pipe connection port set on the upper part of the cement slurry tank, and the grouting pipe is provided between the air pump and the cement slurry grouting port on the inner side of the cement slurry tank. The side of the tank has a one-way water inlet and a one-way water outlet, the top surface has a water tank filling valve and a water tank exhaust valve, and the top of the U-shaped base has a filling and exhausting port, and each water tank filling valve and water tank exhaust valve are connected to The charging and exhausting port is provided with a charging and exhausting pipe between the charging and exhausting port and the air pump. The invention can sink to the bottom of the water and the built-in cement slurry tank can realize the full range of underwater grouting to the scour pit of the pile foundation, the grouting is accurate, and the grouting range is wide.

Description

technical field [0001] The invention relates to a scour pit restoration base, in particular to an intelligent U-shaped base and a method for treating scour pits of bridge pile foundations. Background technique [0002] At present, with the rapid development of my country's economy, water transport projects with large transport volume and low cost are constantly expanding, and more and more bridges are built. However, due to the obstruction of the bridge piers, the water flow will generate a strong eddy current around the bridge piers, which will cause the scour of the bridge pile foundation, which will seriously affect the safety of the bridge structure. According to various research results at home and abroad, the scour disease of the bridge foundation structure is one of the most important reasons for the failure of the bridge structure and the loss of its safety performance. The annual cost of repairing and making up for bridges suffering from foundation scour diseases i...

Problems solved by technology

[0003] At present, most of the existing bridge foundation scour pit repair works use cofferdam construction, and then use concrete and backfill soil to fill the scour pit. The accuracy of uncontrollable repair is low, requiring a lot of manpower and construction machinery, and a large construction ship is required. The repair work is greatly affected by natural conditions, the repair materials are easily washed by water, the repair cost is high, and the repair work period is long. The repair efficiency is low, so it is of great practical significance to develop a repair device for bridge foundation scour pits
