Abstract

The invention provides a grouting reinforcement device for weak karst fillings. It includes a grouting pipe, a grouting barrel and a grouting valve; along the height direction of the grouting barrel, a plurality of partitions are arranged inside the grouting barrel, and two adjacent partitions and the side wall of the grouting barrel form a grout containing chamber , a plurality of telescopic grouting valves are slidably connected to the side wall of the grouting barrel, and each grouting valve is located between two partitions; one end of the grouting pipe provided with a grouting hole passes through the grouting barrel The clapboard is slidably connected with the grouting barrel along the height direction, and piston rings are arranged on both sides of the grouting hole along the height direction of the grouting pipe. In the present invention, multiple layers of grout containing chambers are arranged inside the grouting bucket, and a grouting valve is arranged on the side wall of each grouting chamber, so that the grouting pipe can be applied to the strata of different depths for grouting reinforcement, which can reduce the need for workers to lift Reduce the workload of the overall grouting equipment and improve the efficiency of grouting work.

Description

technical field [0001] The invention relates to the technical field of stratum grouting reinforcement, in particular to a grouting reinforcement device for weak karst fillings. Background technique [0002] The karst area is a geological disaster area, and there are a large number of dissolved soil caves underground. For pile foundations, foundation pits, underground tunnel excavation and other projects, the dissolved soil caves need to be treated first to ensure the safety of construction and use, and avoid construction and use. During the process, safety accidents such as hole collapse, water leakage, and large-scale collapse in the surrounding area were caused by dissolved soil holes. According to geological drilling data, different treatment methods are adopted for the specific conditions of various types of dissolved soil caves. On the one hand, it can ensure the expected treatment effect, on the other hand, it can effectively control the cost and reduce the investment ...
