Introduction: How to cast and embed waterproof casing in concrete construction? The concrete pouring and embedding scheme of waterproof casing belongs to the civil engineering of building structure. Before pouring the wall of building structure, pool, shear wall and civil air defense engineering wall, the waterproof sleeve and concrete pouring method shall be adopted

Waterproof casing How to carry out pouring and embedding in concrete construction? The concrete pouring and embedding scheme of waterproof casing belongs to the civil engineering of building structure. Before the wall pouring, the waterproof sleeve and structural steel bar are tied together and fixed by formwork before the wall pouring. After the concrete is poured, the waterproof sleeve and concrete can be well combined to seal, waterproof and protect the pipeline Use.
The installation steps of waterproof casing are divided into six steps: acceptance before pouring waterproof casing; construction; pouring after wall formwork forming; concrete curing after pouring:
1. Acceptance before pouring of waterproof casing: check the reinforcement, water stop belt, waterproof wing ring, whether the construction data are well done, whether the fixed specification of waterproof sleeve is appropriate, and whether the impurities inside the formwork are cleaned up and accepted.
2. Construction: the construction of waterproof casing should be put in front. Before pouring the casing, a set of construction scheme should be worked out to clear the road obstacles in advance, the working range of tower crane above, and the road surface finishing should be smooth. This necessary condition must be directly informed in place. The actual operator's protection work must ensure that everything is safe (such as insulating rubber shoes, protective gloves, etc.) Only after the construction scheme can concrete pouring be carried out.
3. Pouring after the wall formwork is formed: the waterproof sleeve is the steel sleeve embedded in advance when the building structural wall is poured. Before the structural wall is formed, the waterproof sleeve and the steel embedded pipe material shall be tied and welded in advance, and the concrete pouring can be carried out after the formwork is calibrated and fixed.
Rigid waterproof casing It is composed of casing and wing ring, and its weight is to calculate the weight of casing and wing ring. Rigid waterproof casing of the same caliber has different length. Only the length of the casing is extended, the water stop wing ring is not changed, so the water stop wing ring is a fixed value, and the casing is a variable value
Flexible waterproof casing The measurement method of flexible casing is basically similar to the weight formula of rigid waterproof casing. The weight of 300 length casing is taken as the quantity of flexible casing, and then the weight of each extended length of 100 mm is increased 02s404 waterproof casing The weight can be found in the atlas.
