Grouting reinforcement method suitable for weak filler karst cave
The invention provides a grouting reinforcement method suitable for a weak filler karst cave. The grouting reinforcement device comprises a grouting pipe, a grouting barrel and a grouting valve, a plurality of partition plates are arranged in the grouting barrel in the height direction of the grouting barrel, a grout containing cavity is formed by every two adjacent partition plates and the side wall of the grouting barrel, a plurality of telescopic grouting valves are connected to the side wall of the grouting barrel in a sliding mode, and each grouting valve is located between the two layersof partition plates; and the end, provided with a grout conveying hole, of the grouting pipe penetrates through the partition plate of the grouting barrel to be in sliding connection with the grouting barrel in the height direction, and piston rings are arranged on the two sides of the grout conveying hole in the height direction of the grouting pipe. The multiple layers of grout containing cavities are formed in the grouting barrel, the grouting valves are arranged on the side walls of all the grout containing cavities, the grouting reinforcement device can be suitable for grouting reinforcement of stratums of different depths only by lifting the grouting pipes, the workload of workers for lifting the whole grouting device can be reduced, and the grouting working efficiency is improved.
本发明提供了一种适于软弱充填物岩溶溶洞注浆加固方法。包括注浆管、注浆桶和注浆阀；沿所述注浆桶的高度方向在注浆桶内部设有多个隔板，相邻两隔板与注浆桶侧壁形成一个浆液容纳腔，注浆桶的侧壁上滑动连接有多个可伸缩的注浆阀，每个注浆阀位于两层隔板之间；所述注浆管设有输浆孔的一端穿过注浆桶的隔板与注浆桶沿高度方向滑动连接，沿注浆管的高度方向在输浆孔的两侧设有活塞环。本发明通过在注浆桶内部设置多层浆液容纳腔，在每个浆液容纳腔侧壁设置注浆阀，只需提升注浆管即可适用于不同深度的地层注浆加固，可减少工人提升整体注浆设备的工作量，提升注浆工作效率。
