High polymer deep hole positioning self-enclosed slurry nozzle and slurry system and method thereof

Abstract

The invention discloses a high polymer deep hole positioning self-enclosed slurry nozzle and a slurry system and method thereof. The slurry nozzle comprises a nozzle body the inside of which is hollow; a conveying tube for conveying slurry is arranged inside the hollow cavity; the exit end of the nozzle body is provided with a nozzle; the conveying tube is inserted into the nozzle body from the feeding end of the nozzle body and extends to the exit end of the nozzle body where the conveying tube is connected with the nozzle; the nozzle body is covered with a sealed air bag which is equipped with an inflatable port from where the sealed air bag can be inflated and clinging to the hole wall so as to to achieve sealed slurry; and the nozzle body is also fixed with a first camera for detectingthe location of diseases and a second camera to monitor whether the slurry is saturated. The invention also provides a slurry system and method of the high polymer deep hole positioning self-enclosedslurry nozzle. According to the invention, long-distance transport can be realized, and the deep hole positioning layer-by-layer self-enclosed slurry can meet the requirements of high polymer slurry,and is especially suitable for the construction condition of deep hole and multi-layer disease disposal.

Description

technical field [0001] The invention relates to the technical field of non-excavation restoration engineering of infrastructure such as dikes, dams and pipelines, and in particular to a high polymer deep hole positioning self-sealing grouting nozzle, a grouting system and a grouting method. Background technique [0002] At present, grouting technology, as the main means of foundation treatment and infrastructure engineering reinforcement and repair, has been widely used in various infrastructure fields. Cement grouting technology is relatively mature, but the cement material has high rigidity and insufficient anti-seismic and crack resistance. Therefore, flexible and environmentally friendly polymer materials and their grouting technology have received increasing attention at home and abroad, especially in dikes, dams, The protection and restoration of infrastructure such as expressways, and the rescue of underground engineering such as tunnels and subways have become resear...

Problems solved by technology

[0004] For example, it has been developed: integrated polymer grouting system (ZL201310124851.2), an integrated polymer grouting system (ZL201320180107.X), a trailer-type polymer grouting system (ZL201310124800.X), a A trailer-type polymer grouting system (ZL201320180098.4) can already meet the needs of polymer grouting, but the grouting guns equipped with such equipment systems are usually opened by manually pulling the trigger on the grouting gun Or closed, the mixing method is atomized mixing at the gun head, the grouting material can be mixed evenly and fully, and for engineering treatment of deep holes, the grouting pipe over 15 meters is used, due to the large friction between the material and the inner wall of the grouting pipe The material reacts and solidifies during the transportation process, which is difficult to realize. Since the above-mentioned grouting gun only realizes the mixing of materials, it cannot accurately locate and dispose of geological multi-layer defects
