Method for quickly dismantling failure zones of rock-fill dam concrete faceplate

Abstract

The invention discloses a method for quickly dismantling failure zones of a rock-fill dam concrete faceplate. The method comprises the following steps that according to the failure condition of the concrete faceplate, the dismantling zones of the concrete faceplate are delimited; the concrete faceplate is divided into multiple concrete blocks to be cut by size; and a hydraulic wall sawing system is used for cutting the concrete blocks to be cut from bottom to top. By means of the method, the defects that the dismantling efficiency of rock-fill dam concrete faceplates is low, the dismantling range is hard to control, and the environmental friendliness is poor in the prior art are overcome. The method has the advantages that the cutting speed is high; cut surfaces are smooth and neat; cutting positions are accurate; a dam body and faceplates not dismantled are not damaged; the construction cost is moderate; operation is convenient; pollution is avoided; and noise is low.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, in particular to a method for quickly removing the damaged area of ​​a concrete face plate of a rockfill dam. Background technique [0002] At present, the face rockfill dams in my country are developing rapidly and have a large number. Among the more than 600 face rockfill dams that have been built, many of them have leakage problems, and a few risk-removing panels are seriously damaged; for the damage of concrete panels, the panels need to be removed first when repairing Destroy the area and surrounding concrete, then recast the panels. [0003] The method of removing loose concrete and artificially collecting slag is mostly used in the panel demolition construction, such as hand-pneumatic drill, air pick, steel drill, etc.; this method is used to remove the uneven surface, and the slag is dropped during the upper part construction, and the lower part cannot be constru...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology, and provide a method for quickly removing the damaged area of ​​the concrete face of the rockfill dam, with fast cutting speed, smooth and tidy cutting surface, accurate cutting position, and any angle can be realized through different installation forms of the track The cutting will not damage the dam body and the panel that will not be removed, the construction cost is moderate, and there is no pollution. The cutting process is operated by remote control, which is safe and convenient. The vibration and noise during the cutting process are small. separated
