Embodiment

[0021] The invention provides a rapid airtight construction process, which includes: firstly carrying out grooving operation on both sides of the lane walls; selecting a grooving machine, and the grooving machine is a KC-5 explosion-proof diesel grooving machine, the whole machine can be rotated 360°, and the hydraulic Under the condition of ensuring the quality of the cutting, the cutting time is shortened; then a brick-concrete wall is constructed inside, and mortar is filled between the two brick walls; The loess is mixed into a slurry by using a measure pipe; the slurry is directly pumped into the two walls by a material filling pump, and the two walls can be filled without dead ends, and the filling time can be shortened; a small spraying machine is used. Comprehensive spraying is carried out to ensure the quality and speed of the airtight plastering surface, improve the scope of the airtight plastering surface, completely eliminate the possibility of air leakage on the si...

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...
