Background
In engineering construction such as water conservancy water and electricity, highway, railway, colliery, when facing big buried depth overlength tunnel construction, in order to shorten the time limit for a project, practice thrift the investment, construct as the construction passageway through setting up the shaft, concrete among the tunnel work progress is usually transported to the pit through the shaft, adopt swift current ash pipe vertical transportation concrete mostly, need arrange one set of swift current ash pipe of installation in the shaft, adopt suspension type usually, lay the steady car on ground, suspend the swift current ash pipe in the shaft through two wire rope, generally adopt to weld on swift current ash pipe and hang the lug, suspend in the shaft in order to guarantee smooth ash pipe through fixing wire rope on the lug. The method simultaneously adopts two steel wire ropes which are fixedly suspended by lifting lugs, the suspended verticality of the ash sliding pipe cannot be ensured, so that the ash sliding pipe is quickly worn when the concrete is vertically conveyed, the local part of the lower ash sliding pipe can be worn, the whole pipeline needs to be lifted to the ground section by section through a stable vehicle, after the whole ash sliding pipe in a shaft is completely removed, the damaged pipe sections are replaced, the detection is completely completed, and then the ash sliding pipe is connected with a shaft for installation section by section. This traditional swift current ash pipe is repaired the change mode construction degree of difficulty and is big and danger coefficient is high, the efficiency of construction is low, is unfavorable for engineering construction such as present water conservancy water and electricity, highway, railway to the demand of safety control and economic benefits.
Disclosure of Invention
Aiming at the technical problems, the utility model provides a quick repairing device which is convenient to operate, safe, reliable, practical and efficient when an ultra-deep shaft ash chute is repaired.
In order to solve the technical problem, the utility model provides a quick repairing device for an ash slipping pipe of an ultra-deep shaft, which comprises the ash slipping pipe, wherein the quick repairing device comprises an outer lining reinforcing steel plate, an inner lining flexible material, an annular steel plate pipe hoop, a high-strength connecting bolt and lug plates, the lug plates are welded on two sides of the outer lining reinforcing steel plate, the connecting bolt hole is drilled in the middle of the lug plates, the outer lining reinforcing steel plate is tightly attached to the ash slipping pipe, the inner lining flexible material is arranged between the outer lining reinforcing steel plate and the ash slipping pipe, and the annular steel plate pipe hoop is connected with the outer lining reinforcing steel plate through the lug plates and the high-strength connecting bolt.
Furthermore, the two sides of the outer lining reinforcing steel plate are welded with lug plates, and connecting bolt holes are drilled in the middle positions of the lug plates.
Further, the expanded shape and the size of the inner lining flexible material are consistent with those of the outer lining reinforced steel plate.
Furthermore, the annular steel plate pipe hoop is in a semicircular shape, and the outer lining reinforcing steel plate is tightly attached to the ash sliding pipe by adjusting the fastening degree of the high-strength connecting bolt.
The utility model has the beneficial effects that:
the high-strength connecting bolt fastens the outer lining reinforcing steel plate, the inner lining flexible material and the damaged part of the ash sliding pipe firmly through the two groups of steel plate pipe hoop end bolt holes, and ensures that the perforated part of the ash sliding pipe is tightly plugged and repaired through the flexible contact of the flexible material and the ash sliding pipe and the steel plate outer lining rigid support, so that the structure is safe and firm. Compared with the traditional repair and replacement mode of the ash sliding pipe, the ash sliding pipe does not need to be dismantled, and the construction efficiency and safety are improved.
