Hollow sectional type pressurizing grouting system with pressure hole sealing function and method of hollow sectional type pressurizing grouting system
The invention relates to the technical field of geotechnical engineering grouting, in particular to a hollow sectional type pressurizing grouting system with an under-pressure hole sealing function and a method of the hollow sectional type pressurizing grouting system. According to the technical scheme, the device comprises a slurry channel pipe, the top of the slurry channel pipe is fixedly sleeved with a supporting disc, a hopper is fixed to the top of the supporting disc, the bottom of the hopper is communicated with the slurry channel pipe, and the device further comprises a bubble removing device. According to the method, bubbles in grouting slurry can be effectively eliminated, the bubbles are effectively prevented from entering cracks of the cofferdam, the compactness of grouting is improved, the stability of surrounding rock is improved, segmented controllable grouting is achieved, meanwhile, the engineering problems that previous roadway superficial grouting is likely to permeate preferentially, the deep grouting efficiency is low and the like are effectively solved, drilled holes are segmented and isolated, and the construction efficiency is improved. And the grouting pressure of each section is increased, grouting permeation is increased, and it is ensured that broken surrounding rock is effectively modified.
本发明涉及岩土工程注浆技术领域，尤其涉及一种具备带压封孔功能中空分段式增压注浆系统及其方法。其技术方案包括浆通道管，所述注浆通道管的顶部固定套设有支撑盘，所述支撑盘的顶部固定有料斗，所述料斗的底部与注浆通道管连通，还包括气泡去除装置。本发明可以有效地消除注浆浆料中的气泡，有效地避免气泡进入到围堰的裂缝中，提升注浆的密实性，提高围岩的稳固性，实现分段可控注浆，同时有效解决以往巷道浅表注浆易优先渗入、深部注浆效率低等工程难题，对钻孔进行分段隔离，提高各区段注浆压力，增加注浆渗入，确保有效改性破裂围岩。
