Rapid sealing construction technology

Abstract

The invention discloses a rapid closed construction process. The rapid closed construction process comprises the steps that firstly, underholing operation is conducted on roadway walls on the two sides; a grooving machine is selected, and a hydraulic system is used for grooving; then, brick-concrete walls are constructed inside, and the space between the two brick walls is filled with mortar; loess is mixed into slurry through a measure pipe arranged between the two walls of the external wall body in a pressed mode; the slurry is directly pumped into the space between the two walls by using a material filling pump, so that the space between the two walls can be filled without dead angles; a small spraying machine is selected for comprehensive spraying in the range before sealing; the airtight construction speed is increased, and it is guaranteed that the goaf can be sealed in time; the sealing construction quality is improved; the labor intensity is reduced, advanced equipment is used at multiple positions in the working procedure to replace manual work, the proportion of manual work in the most heavy working procedure in the whole closed construction such as slotting, filling and plastering is reduced, and the working intensity of workers is reduced; and the construction safety is ensured.

Description

technical field [0001] The invention relates to the technical field of mine construction, in particular to a rapid sealing construction process. Background technique [0002] Due to the continuous application of new technologies and new equipment, the mining speed of the mine has been continuously improved, and there are faster and better requirements for the closed construction technology of the mine; [0003] At present, the mine airtight construction speed is relatively slow, some construction personnel are unskilled, the craftsmanship is rough, the air leakage during the construction airtightness and the quality of the wall are not enough. For this reason, we propose a fast airtight construction process. SUMMARY OF THE INVENTION [0004] In order to overcome the deficiencies of the prior art, the present invention provides a rapid sealing construction process, which speeds up the sealing construction speed, ensures that the goaf can be sealed in time, improves the seal...
