The sealing layer can be formed at the wall penetrating part of the pipeline through brushing the sealant, and the sealing layer has good elasticity and adhesion performance, so that the dry and hard cement mortar can be used for plugging the hole area, thereby filling the gap between the pipeline and the wall, reducing the infiltration of moisture into the room or the exudation of the moisture out of the room from the gap between the wall, and secondly, under the matching effect of the sealing sealant and the dry and hard cement mortar, the flowing of air and dust in the area can be reduced, thereby being beneficial to enhancing the connection stability between the wall and the pipeline, and enabling the sealing effect of the sealing layer and the wall to be more durable.

In the screw hole node treatment procedure, firstly, a trumpet-shaped hole is drilled on the outer side of a screw hole, then, after flushing and wetting, the hole is filled with waterproof mortar, at the moment, attention is required to avoid the condition of empty holes, a round cake shape is complemented on the outer side and protrudes out of a wall surface, and finally, a hole is maintained through mortar, so that fine cracks or empty drums cannot be obtained; if the screw hole node appears on the basement outer wall 1, a water stop bolt is needed to replace the process.

In the air conditioner reserved hole node treatment process, the PVC sleeve reserved by the air conditioner is reserved, meanwhile, the steel sleeve is reserved in the beam, a prefabricated concrete block is reserved in the wall body, the reserved pipe is required to be inclined outdoors, the inner pipe orifice is 20-30 mm higher than the outer pipe orifice, and the outer pipe orifice protrudes out of the outer wall decoration surface by 60-80 mm, so that the inner pipe orifice is flush with the inner wall decoration surface.

In the floor pipeline hole processing procedure, a sleeve is required to be arranged when a pipeline penetrates through a roof, the sleeve is required to be paid out on a template and accurately and firmly fixed before a floor is poured, the upper opening of the sleeve is higher than the ground finishing surface by not less than 50mm, the lower opening is flush with the floor bottom, and when no design requirement exists, the pipe diameter of the sleeve is required to be larger than that of the pipeline for a small-pipe-diameter pipeline; for large-diameter pipelines, the diameter of the sleeve is larger than the outer diameter of the pipeline by 50mm, and in addition, when floor slab concrete is poured, the two ends of the sleeve are sealed by rubberized fabrics, so that the blockage is avoided.

In the application, a sleeve is required to be arranged when a pipeline penetrates through a floor slab; when the through floor pipe is not sleeved, the hole position must be accurately reserved on the floor during the construction of the structure, so that the later drilling and the punching are avoided. In order to facilitate hole plugging, a shaping template can be used for reserving holes in structural construction, the holes are made into a shape with a large upper part and a small lower part, the diameter of the upper part is 40mm larger than that of the lower part, and the holes are timely demoulded after the concrete is finally set. The reserved holes are preferably 60mm larger than the outer diameter of the pipeline, pipe clamps are required to be arranged for fixing all the floor penetrating pipelines during installation, fine stone concrete is adopted for blocking the pipe holes for two times for preventing leakage, and a 20mm groove is required to be reserved after the second time of blocking. After the water is closed and inspected to be qualified, the waterproof construction of the periphery of the pipeline can be started.

In the flue node treatment procedure, in order to reduce the large accumulated sedimentation caused by stack of the flue layers, the floor waterproof layer 2 is damaged and the flue gas duct is cracked, the lower part of the flue is arranged on the reverse ridge, the upper part of the flue props against the structural floor slab, and the gap between the upper part and the lower part of the flue is tightly blocked by cement mortar.

The concrete guide wall and the floor concrete can be poured together or secondarily poured, but before the secondarily poured concrete guide wall is constructed, the concrete at the lower part of the parapet wall needs to be roughened, cleaned and fully wetted.

After the construction of the waterproof layer 2 is completed, a waterproof protective coating, waterproof protective mortar or waterproof protective plates are paved on the top surface of the waterproof layer 2, so that the influence of external factors on the waterproof layer 2 is reduced, or the waterproof layer 2 is damaged, the durability, puncture resistance and impact resistance of the waterproof layer 2 can be enhanced, and the protection effect on the waterproof layer 2 is achieved.
