Type B rigid waterproof casing

Type B rigid waterproof casing is suitable for structures (buildings) where the pipeline passes through the wall and does not bear pipeline vibration and expansion deformation. For areas requiring seismic fortification, if steel waterproof casing is used, flexible connection shall be set near the pipeline entering pool wall or building outer wall. Type B rigid waterproof sleeve is suitable for ductile iron pipe.

Description of type B rigid waterproof casing:
Type B rigid waterproof casing is applicable to the structures (buildings) where the pipeline passes through the wall and does not bear pipeline vibration and expansion deformation. For areas requiring seismic fortification, if steel waterproof casing is used, flexible connection shall be set near the pipeline entering pool wall or building outer wall. Type B rigid waterproof sleeve is suitable for ductile iron pipe.
?

B type rigid waterproof casing pipe construction:
First, the main pipe of waterproof casing adopts ductile iron pipe, rubber ring socket joint, d325 × 8 welded steel pipe is used for bridge crossing pipe, and d219 × 6 welded steel pipe is used for embedded branch pipe along the road.
Secondly, before the construction, the pipe fittings and valves should be tested, and the pressure level should not be lower than 1.5 times of the working pressure of the pipeline. After the materials enter the site and before the pipe laying, the pipes and accessories should be inspected, including written certificates and physical inspection.
Third, it is strictly forbidden to throw or collide violently in the process of transportation, loading and unloading and stacking. The laying of pipes shall be carried out only after the trench inspection is qualified. Before laying the pipes, the appearance of pipes and fittings shall be re inspected, and the pipes and fittings with problems shall not be used.
Fourth, when the waterproof casing pipe is hoisted and put into the groove, the reliable soft belt sling should be used, and the trench bottom and groove wall should not be collided violently. The pipes are distributed along the trench to reduce the secondary handling. In order to ensure the accuracy of the pipe laying position, it is necessary to place a level ruler with a center scale in the pipe. During the inspection, check whether the center suspension line sagging on the pipeline coordinate center line coincides with the center of the level ruler.
