Jet Grouting Technology In Dam Base Processing

The jet-grouting is one kind uses the high-pressured water or the high-pressured size forms the high speed spraying striation. Impact, cutting, stave stratum soil body. Among and by the cement matrix size backfill, mixes mixes. Forms the pile or the wooden fence shape congealment body. With enhances the ground to guard against infiltrates or the bearing capacity construction technology. This technology is small to the dam original structure influence. The construction is simple. Project construction cost relative low. Guards against to the dam base infiltrates the reinforcement to have the obvious technical superiority.On century 50~70 age our country has constructed a large quantities of reservoir project. In which is very big a part for to use the local material reclamation the earth stone dam. In view of the fact that level of understanding and construction ability limit then. Special has not guarded against to the dam base infiltrates the processing measure or guards against infiltrates the processing measure to be insufficient. Creates the serious dam base leakage problem. Existence very big security hidden danger. Degenerates into sickness danger dam. Has restricted the reservoir security and the benefit display enormously.This topic is ties the closure river mouth reservoir. The horizontal platoon guide key position two large-scale hydraulic engineering dam base guards against infiltrates the reinforcement the actual request. Through field test and project construction. To spurts the grouting cut-off wall high the formation principle and the action mechanism carries on further analyzes the research. In view of sickness danger dam dam base permeable bed reinforcement concrete characteristic. The research being suitable dam base processes jet-grouting grouting technology plan, craft parameter. The summary reorganizes controls spurts the cut-off wall high in the quality control measure and the construction should the key attention question. Guards against for later jet-grouting technology in other infiltrates the project the application to provide the reference experience.
