Method for filling underground cavity of bedrock stratum through filler grouting and hydraulic filling device
The invention relates to the technical field of karst cave filling, provides a method for filling an underground cavity of a bedrock stratum through filler grouting, and particularly relates to a filling method of a deep-covering type (burial depth is larger than 30.0 meters) large-space karst cave and a roadway. The method comprises the steps of determining a drilling position, drilling a covering soil layer, arranging a conveying casing pipe, drilling a bedrock section, filling by a hydraulic filling method and grouting. According to the method, the underground cavity is filled with the gravel material through the hydraulic filling method, then grouting is conducted, the filled gravel material is solidified, and the integrity of the filling material is improved; and the filled gravel materials can occupy the space in the underground cavity, the grouting amount is greatly reduced, the treatment cost is reduced, a connecting channel between the cavity and the outside of the cavity canbe blocked or reduced, the filling treatment effect of the underground cavity is improved, and the filling treatment problem of the deep covering type large-space karst cave and the roadway is solved.The invention further provides a hydraulic filling device, the hydraulic filling device is used for filling the underground cavity with gravel materials, the filling speed is high, and the filling effect is good.
本发明涉及溶洞充填技术领域，提供了一种填料注浆充填基岩层地下空洞的方法，特别是深覆盖型(埋深大于30.0米)大空间溶洞以及巷道的充填方法，包括确定钻孔位置、覆盖土层钻进、下设输料套管、基岩段钻进、水力冲填法填料和注浆。本发明先采用水力冲填法向地下空洞内充填砂石料，再进行注浆，凝固充填的砂石料，提高充填材料的整体性。充填的砂石料既可占据地下空洞内空间，大幅减小注浆量，降低处理成本，又可封堵或减小空洞与洞外的连接通道，提高地下空洞的充填处理效果，解决了深覆盖型大空间溶洞以及巷道的充填处理难题。本发明还提供了一种水力充填装置，利用发明的水力充填装置向地下空洞内充填砂石料，充填速度快，充填效果好。
