Abstract

The invention discloses a column beam type grouting device and a hole sealing and grouting technology of the grouting device. The grouting device comprises a grouting pipe connecting device and a high-pressure sluice valve. The grouting pipe connecting device comprises an upper ring flange, a lower ring flange and a middle short connecting pipe. A grouting pipe connector is arranged on the outer side of the middle short connecting pipe of the grouting pipe connecting device. A short casing is connected to the interior of the middle short connecting pipe of the grouting pipe connecting device. A fixing device is arranged below the grouting pipe connecting device and comprises an upper ring flange, a lower ring flange and a middle short connecting pipe. An I-steel column beam is welded to the outer side of the middle short connecting pipe of the fixing device. The two ends of the I-steel column beam are symmetrically provided with balance weights. A casing connector is connected to the lower ring flange of the fixing device. The lower end of the casing connector is connected with a long casing which downwards penetrates through an original hole. The lower ring flange of the grouting pipe connecting device is connected to the upper ring flange of the fixing device. The upper ring flange of the grouting pipe connecting device is connected with the high-pressure sluice valve. The grouting problem under the condition that an original water supply hole casing is damaged seriously is solved, and economic benefits are remarkable.

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...
