Apparatus and method for grouting and pile quality inspection of occlusal piles used for water-blocking curtains

Abstract

A device and method for detecting the grouting and pile body quality of a water-blocking curtain, the device at least includes a grouting pipeline, a check valve, a counterweight ring, a grouting pipe end, a distributed optical fiber grating, and a grouting pipe joint , embedded in the pouring pipeline is a distributed fiber grating, which is used to test the integrity of the pile body of the occlusal pile and monitor the stress and strain of the water blocking curtain during the operation period. The lower end of the pouring pipe is connected to the end of the grouting pipe, and the grouting pipe A check valve is set between the end and the grouting pipeline, the end of the grouting pipeline is provided with a counterweight ring, the upper end of the grouting pipeline is provided with a quick connector for the grouting pipe, and the quick connector for the grouting pipe is connected to the grouting pipeline. Quick connection of pipeline joints; thus, the present invention can effectively solve the problems of slow construction of adjacent anti-seepage membrane occlusal piles, high construction cost, difficulty in connecting perfusion conduits, inconvenient operation, high mechanical requirements, large construction site, and inconvenient pile detection and monitoring The problem.

Description

technical field [0001] The present invention relates to the technical field of underground interception, anti-seepage and pollution control such as mine curtains, water-cutting curtains of water conservancy projects, pollutant blocking and isolation, foundation pit water-stopping curtains, etc. Pile body quality detection device and method. Background technique [0002] The occlusal piles are partially embedded in the circumference of the adjacent concrete row piles, and the steel cages are placed in the piles of the subsequent sequential construction to form an overall continuous waterproof and soil retaining maintenance structure with good anti-seepage effect. The arrangement of the occlusal piles is an unreinforced ultra-retarded concrete pile and a reinforced concrete pile arranged at intervals. During construction, the plain concrete piles are constructed first, and then the reinforced concrete piles are constructed. The construction of the reinforced concrete piles is...
