A grouting device for soil nailing wall slope support

Abstract

The invention belongs to the technical field of slope support, in particular to a grouting device for soil nail wall slope support. Aiming at the problems of simple design structure, time-consuming and laborious, and poor grouting effect, the following scheme is proposed, including the base, The four corners of the top of the base are connected with support columns by fastening bolts, and the tops of the four support columns are connected with the same mounting plate by fastening bolts, and one side of the mounting plate and one side of the base are fastened The same mixing chamber is connected by bolts, the first fixing block is connected to one side of the top of the installation plate through fastening bolts, and the first hydraulic oil cylinder is connected to the top of one side of the first fixing block through fastening bolts. The invention is convenient for drilling, saves time and effort, and effectively prevents dust from spreading in the air to damage the health of workers, improves the effect of grouting, ensures uniform cement mixing, effectively prevents grouting bolts from falling off, and improves the quality of grouting , and convenient and easy to operate.

Description

technical field [0001] The invention relates to the technical field of slope support, in particular to a grouting device for soil nail wall slope support. Background technique [0002] At present, in civil engineering construction, for slope support engineering, the soil is extremely loose, and most of them are sandy soil with high water content, cohesive soil with high plasticity and loose sandy soil with saturated water. Once the soil cannot be quickly anchored, it will easily lead to changes in the broken state and mechanical properties of the slope rock and soil, reducing the stability and integrity of the slope. Bolt support is an important form of geotechnical engineering support. , after retrieval, the Chinese patent authorization number is the patent of CN206385555 U, discloses a kind of civil engineering slope bolt grouting head device, comprises driving sleeve and is placed on the outer wall of one end of the main body tube, and the annular fixed plate is placed on...

Problems solved by technology

[0002] At present, in civil engineering construction, for slope support engineering, the soil is extremely loose, and most of them are sandy soil with high water content, cohesive soil with high plasticity and loose sandy soil with saturated water. Once the soil cannot be quickly anchored, it will easily lead to changes in the broken state and mechanical properties of the slope rock and soil, reducing the stability and integrity of the slope. Bolt support is an important form of geotechnical engineering support. , after retrieval, the Chinese patent authorization number is the patent of CN206385555 U, discloses a kind of civil engineering slope bolt grouting head device, comprises driving sleeve and is placed on the outer wall of one end of the main body tube, and the annular fixed plate is placed on the inner wall of the main body tube , and located in the middle position, a plurality of connecting brackets are evenly placed on one end of the grouting pipe, and the other end of the grouting pipe passes through the center of the ring-shaped fixing plate and is connected with the connecting sleeve. Multiple expansion plates pass through the rotating shaft respectively. Placed on the other end of the main cylinder, multiple expansion plates cooperate to form an inverted conical shape, and multiple fixing brackets are respectively placed on the expansion plates

A kind of civil engineering slope bolt grouting head device in the above-mentioned patent has the following disadvantages: the design structure is simple, time-consuming and labor-intensive, and the grouting effect is not good
