Abstract

The invention discloses a column-beam type grouting device and its hole-sealing grouting process, which comprises a grouting pipe connection device and a high-pressure gate valve. A grouting pipe joint is provided on the outside of the middle short connecting pipe of the grouting pipe connecting device, and a short casing is connected in the middle short connecting pipe of the grouting pipe connecting device; a fixing device is provided under the grouting pipe connecting device, and the fixing device includes , the lower two flanges and the intermediate short-connection pipe, and the I-shaped steel column beam is welded on the outside of the intermediate short-connection pipe of the fixing device. There is a casing joint on the top; the lower end of the casing joint is connected to the long casing that is lowered into the original hole; the lower end flange of the grouting pipe connection device is connected to the upper end flange of the fixing device, and the upper end of the grouting pipe connection device The flange is connected to the high-pressure gate valve. This invention solves the problem of grouting when the casing of the original water supply hole is seriously damaged, and has remarkable economic benefits.

Description

technical field [0001] The invention relates to a grouting device and a hole sealing process, in particular to a column-beam type grouting device and a hole sealing and grouting process. Background technique [0002] At present, for the discarded water supply holes in the underground tunnels of mines, it takes a lot of people, money, material resources and electricity to drain and treat water. Groundwater pours into shafts and turns into sewage. If it is discharged from the ground and directly enters the surface water body, it will cause serious pollution to the surface water environment. When many water supply holes are scrapped in the mining area, it will seriously lead to a large-scale drop in the groundwater level, which will intensify the pollution of cities and towns near the mining area. 1. The shortage of water for industrial and agricultural production in rural areas, especially causing serious harm to agricultural production. At present, when the water supply hole...
