Biogas tank maintenance method

1, the pool wall crack treatment. Dig the crack deeper, widen it into "V" shape, pull around the hair, remove the debris, brush with a pure cement slurry, and then use a 1:2 cement mortar to inlay and polish the cement mortar after solidification for 12 hours. Brush 2 times pure water slurry again.

2, the wall and bottom junction crack treatment. First, the crack is deepened, widened, and the edge is cut. After cleaning, the pure cement paste is brushed once and then compacted with 1:2 cement mortar, and the pure cement slurry is brushed once more. After 24 hours, use a 1:2 cement mortar to wipe the joint between the pool wall and the bottom of the pool into large rounded corners, and finally brush the pure cement slurry once.

3, vault and ring beam crack treatment. Remove the vaulted soil until the ring beam is exposed. Cracks in the vaults should be repaired according to the treatment method of the cracks in the pool wall at both the inner and outer sides. After the repair is completed, the mud around the ring beams shall be tamped, and then the soil cover be refilled. If the ring beam breaks, it should be brushed clean around the ring beam, brush 1 time pure cement slurry, with a 150-degree concrete in the ring around the outside of the ring to build a ring to strengthen the beam, put a rebar within 2, to be strengthened After the beam concrete reaches 50% strength, it will be backfilled with earth.

4, bottom sinking treatment. Dig up the cracked and broken part, remove the soft soil, fill it with gravel or block stone, and pour 150 concrete on the filling layer, 5 centimeters thick, and coat the surface with 1:2 cement mortar once. Note that the repair surface should exceed the damaged surface.

5, stucco seal layer treatment. For ill-conditioned pools in which the stucco layers are damaged, such as shedding, warping, cracking, etc., during the repair, the damaged parts should be scooped with a net cut, and then a 5-layer plaster cement mortar waterproof layer should be used to paint the seal layer. The first layer is a pure gray layer, first wipe 1mm pure cement paste as a bonding layer, use an iron trowel to wipe back and forth several times, and then wipe 1mm pure grout, smooth, and use a brush to pull the surface into a hairline. The second layer is a cement mortar layer. The mix ratio of cement to sand is 1:2.5 and the thickness is 4.5 mm. After the first layer, it is done. Every 3 days, the 3rd floor was wiped with pure grout and 2 mm thick. Then wipe the 4th layer of cement mortar, 4-5 mm thick. When the mortar is a bit damp, but does not stick to the hand, do the 5th layer. Brush the pure cement paste with a brush in turn and dry the surface slightly.

6, leakage treatment. For the leakage hole, water glass is used to mix cement mortar for plugging, cement: water glass = 1:0.6, and the cement mortar is used to fill the leaking hole of the cement mortar. .

7, chronic leakage treatment. For a small amount of blisters, capillary leaks caused by chronic leakage, biogas digester can be part of the fermentation tank to clean up the gas, and then use pure cement slurry brush 2-3 times.

8. Leakage treatment at air exchange pipe and movable cover exchange. If the air pipe is not loose or leaks around, the concrete on the inner and outer sides of the air pipe can be cut, cleaned, brushed with pure cement slurry for 1 time, and then cemented with 1:2 cement to make up for compaction. Then the inner and outer surfaces are brushed. 2 times pure cement slurry; if the air pipe has been loosened, the air pipe can be pulled out, the surface of the outer wall of the air pipe is shaved, the cement mortar with higher number is re-poured, and locally thickened to ensure the air pipe is fixed.

9. Cover leakage treatment. For the parts where the movable cover mouth is seriously damaged, the surface shall be shaved, cleaned, brushed with pure cement slurry for 1 time, then repaired with 1:2 cement mortar, and then brushed with pure cement paste. For areas with minor damage, brush 1-2 times pure grout.

10. Incoming and outgoing pipe cracks or fractures. Cracked or broken pipes should be dug out and reinstalled. Before installation, the outside of the tube must be brushed with pure grout for 2-3 times, and then filled with fine stone concrete No. 200 at the joint.
