Embodiment
Referring to Fig. 1-2, the processing side that the wall between a kind of air channel and gas pipe provided in an embodiment of the present invention is damaged
Method, based on the wall body structure between air channel and gas pipe, the wall body structure includes：The oblique section wall 3 of coal gas pipe protection wall
And the former cast bed of material 2, the oblique section wall 3 of coal gas pipe protection wall is connected with the gas pipe 1, the former cast bed of material 2 and
The oblique section wall 3 of coal gas pipe protection wall and gas pipe 1 are connected；It the treating method comprises following steps：This method is
Based on the wall body structure between the air channel and gas pipe in Fig. 2, so either specification or claims, is all needed
First to introduce the structure of wall.
Step 1, to the wall position do not collapsed between air channel 8 and gas pipe 1 according to being convenient for constructing and protect
Principle targetedly reinforced.
Step 2, the oblique section wall 3 of coal gas pipe protection wall is repaired by way of one-piece casting.
Step 3, the top surface after the oblique section wall 3 of the coal gas pipe protection wall solidifies builds supporting brick post 6 by laying bricks or stones.
Step 4, by the wall of gas pipe 1 above the oblique section wall 3 of the coal gas pipe protection wall with the insertion of air channel 8 with whole
Body pouring type is repaired.
Step 2 is discussed in detail.
The oblique section wall 3 of coal gas pipe protection wall of being repaired by way of one-piece casting includes：The coal gas pipe protection
The oblique section wall 3 of wall and its damaged location wall of the above take segmentation to give using the integrated poured mode of gravity flow pouring material 7
Repair.The final stage that the oblique section wall 3 of coal gas pipe protection wall is poured into a mould, in the oblique section wall 3 of the coal gas pipe protection wall
Top surface reserve groove 5, the cast for lower step plays fixation, and tortuous reciprocal labyrinth-like is formd in wall seam crossing
Seam, makes sealing effectiveness more preferably, can effectively prevent from collaborating between air channel 8 and gas pipe 1.Pouring into a mould the coal gas pipe protection wall
Before the oblique section wall 3 of body, expanding screw is installed at interval on the former cast bed of material 2 of the oblique behind of section wall 3 of the coal gas pipe protection wall
Bolt.Anchoring hook 4 is fixed with the expansion bolt, the globality of castable is kept, the connection of the bed of material and old wall is poured into a mould in enhancing,
Because old wall is castable, so needing first to beat expansion bolt to weld anchoring hook 4.
Step 3 is discussed in detail.
The top surface after the oblique section wall 3 of the coal gas pipe protection wall solidifies, which builds supporting brick post 6 by laying bricks or stones, to be included：The branch
Support brick post 6 is stayed in integrated poured wall as anchored brick or " reinforcement ", to strengthen the structural stability of repaired wall.
Step 4 is discussed in detail.
The wall of gas pipe 1 by the oblique top of section wall 3 of the coal gas pipe protection wall and air channel insertion is with entirety
Pouring type, which is subject to reparation, to be included：The oblique top of section wall 3 of coal gas pipe protection wall and the wall of gas pipe 1 of the insertion of air channel 8
Body is repaired in the way of integrated poured gravity flow pouring material, constructed between air channel 8 and gas pipe 1 together with it is closely knit whole
Body wall.
The one-piece casting mode is completed using pumping casting construction method so that the intensity and efficiency of construction are obtained for
It is effective to improve.
In order to become apparent from introducing the embodiment of the present invention, introduced below from the application method of the embodiment of the present invention.
Before reparation, to the wall position do not collapsed between air channel 8 and gas pipe 1 according to being convenient for constructing and prevent
The principle of shield is targetedly reinforced, and prevents furnace wall is secondary from collapsing, and uses the instruments such as channel-section steel, angle bar with the position that will not cave in
Support.Segmentation is taken to be poured using gravity flow the damaged location wall of the oblique section wall 3 of burner coal gas pipe protection wall and its above
The integrated poured mode of material feeding 7 is repaired, the construction method of the pumping perfusion self-flowing material of use so that the intensity and effect of construction
Rate is obtained for effective improvement.Pour into a mould before the oblique section wall 3 of burner coal gas pipe protection wall, in the oblique section of coal gas pipe protection wall
200mm is spaced on the former cast bed of material 2 of the behind of wall 3, expansion bolt is installed, and the anchoring for the length 150mm that burn-ons on bolt
Hook 4, keeps the globality of castable, the connection of the enhancing cast bed of material and old wall, because old wall is castable, so needing
Expansion bolt is first beaten to be used for welding anchoring hook.The final stage that the oblique section wall 3 of coal gas pipe protection wall is poured into a mould, in coal gas pipe protection
The oblique top surface of section wall 3 of wall reserves 50mm × 50mm groove 5, and fixation is played in the cast for lower step, in wall seam crossing
Tortuous reciprocal labyrinth-like seam is formd, makes sealing effectiveness more preferably, can effectively prevent from collaborating between air channel 8 and gas pipe 1.
Build the reinforcing done before the replacement repairing construction of supporting brick post 6 by laying bricks or stones in the top surface for the oblique section wall 3 of coal gas pipe protection wall being cured
Support, meanwhile, these supporting brick posts as anchored brick or " reinforcement " stay in then with gravity flow pouring material 7 done it is integrated poured
In wall, to strengthen the structural stability of repaired wall.By the oblique top of section wall 3 of coal gas pipe protection wall and air channel 8
The wall of gas pipe 1 of insertion is repaired in integrated poured mode, the construction method of the pumping perfusion self-flowing material of use so that apply
The intensity and efficiency of work are obtained for effective improvement.
It should be noted last that, above embodiment is merely illustrative of the technical solution of the present invention and unrestricted,
Although the present invention is described in detail with reference to example, it will be understood by those within the art that, can be to the present invention
Technical scheme modify or equivalent substitution, without departing from the spirit and scope of technical solution of the present invention, it all should cover
Among scope of the presently claimed invention.
