Description

Protection architecture of PVC pipe
Technical Field
The utility model relates to a protection architecture of PVC pipe mainly is applicable to the PVC pipe of burying between concrete structure and the soil matrix.
Background
PVC pipe is made up by using polyvinyl chloride resin, stabilizing agent and lubricating agent through the processes of mixing, hot-pressing and extrusion forming. The PVC pipe has strong corrosion resistance, easy adhesion, low price and hard texture. The PVC pipeline is well commented by the engineering industry by virtue of the characteristics of light dead weight, corrosion resistance, high compressive strength, safety, convenience and the like. In civil engineering, PVC pipes are often buried in concrete structures and foundations. Due to the differential settlement of the soil foundation and the concrete structure, the PVC pipe at the contact position is easy to be sheared and damaged to form a leakage point. The adoption of any structure can ensure the integrity and reliability of the PVC pipes arranged in the soil foundation and the concrete structure, and becomes a great difficulty for design engineers.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: aiming at the existing problems, the protection structure of the PVC pipe is provided, and is mainly suitable for the PVC pipe embedded between a concrete structure and a soil foundation. Therefore, the utility model adopts the following technical scheme:
a protection structure of PVC pipes comprises a concrete structure and a soil foundation, wherein one part of pipe sections of the PVC pipes are positioned in the concrete structure, and the other part of pipe sections are positioned in the soil foundation;
embedding a section of steel sleeve at the position of an outlet of the PVC pipe penetrating through the concrete structure, wherein the inner diameter of the steel sleeve is larger than the outer diameter of the PVC pipe, and the first PVC pipe section penetrates through the steel sleeve; flexible filler is filled between the steel sleeve and the PVC pipe;
installing a section of thick PVC sleeve at the penetrating position of a PVC pipe section which needs to be embedded into the soil foundation after penetrating out of the concrete structure, wherein the PVC pipe penetrates through the thick PVC sleeve; the inner diameter of the thick PVC sleeve is larger than the outer diameter of the PVC pipe, and flexible filler is filled between the thick PVC sleeve and the PVC pipe.
Further, the flexible filler may be polyethylene foam.
Further, the centerline of the coarse PVC casing is aligned with the centerline of the steel casing.
Further, the steel sleeve is connected with the concrete structure into a whole through concrete pouring, and the thick PVC sleeve is buried in the backfill soil.
Owing to adopt the technical scheme of the utility model, simple structure, the construction is convenient, has alleviated the shearing destruction that leads to when the structural plane differential settlement, ensures to arrange integrality and the reliability of PVC pipe in soil matrix and concrete structure. Meanwhile, the steel sleeve and the PVC sleeve provide deformation allowance for the PVC pipes on two sides of the contact surface, and the combined action of the two sleeves greatly improves the anti-settling deformation capacity of the PVC pipes.

Detailed Description
Reference is made to the accompanying drawings. The utility model provides a pair of protection architecture of PVC pipe includes following structure:
(1) for the PVC pipe 2 which needs to be embedded into the concrete structure 1, a section of steel sleeve 3 is embedded at the position of an outlet of the PVC pipe 2 which penetrates out of the concrete structure 1, the inner diameter of the steel sleeve 3 is larger than the outer diameter of the PVC pipe 2, and the PVC pipe 2 penetrates through the steel sleeve 3.
(2) The flexible filler 4 is filled between the steel sleeve 3 and the PVC pipe 2, the flexible filler 4 can prevent impurities from entering a gap, and meanwhile, the deformation allowance of the PVC pipe 2 is guaranteed. After the flexible filler 4 is filled, the concrete structure 1 can be poured, the steel sleeve 3 is connected with the concrete structure 1 into a whole through the pouring of concrete, and the PVC pipe 2 outside the steel pipe is also buried in the concrete structure when the concrete is poured.
(3) For the PVC pipe 6 which is required to be embedded into the soil foundation 5 after penetrating out of the concrete structure 1, a section of thick PVC sleeve 7 is arranged outside the soil foundation 5, the thick PVC sleeve 7 is close to the position where the PVC pipe 2 penetrates out of the concrete structure 1, and the center line of the thick PVC sleeve 7 is aligned with the center line of the steel sleeve 3 as far as possible. The PVC pipe 6 to be embedded into the soil foundation 5 is sleeved outside by the thick PVC sleeve 7, and the inner diameter of the thick PVC sleeve 7 is larger than the outer diameter of the PVC pipe 2, so that the deformation allowance is provided for the PVC pipe 6 in the soil foundation 5.
(4) The flexible filler 4 is filled between the thick PVC sleeve 7 and the PVC pipe 6. The flexible filler 4 can prevent soil from entering the gap and ensure the deformation allowance of the PVC pipe 6. After the installation is finished, soil material backfilling can be carried out on the soil foundation 5, and the coarse PVC casing 7 is buried in the backfilled soil.
The flexible padding 4 can be made of polyethylene foam.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art can change, add or replace the above examples within the scope of the present invention.
