[0002] In the process of municipal construction, polyethylene hollow wall winding pipes are generally used for buried drainage, and its diameter is relatively large. The ring stiffness of this type of plastic buried drainage pipe can generally reach the level of SN8; and the hollow winding pipes in two segments The weak link between the pipes is easy to delaminate and crack under the action of external force, resulting in easy deformation of the pipes, reduced service life of the pipes, and potential safety hazards. Generally, regular inspections are required, and timely maintenance is required when damage is found. very high cost

Embodiment 1
[0040] Such as figure 1 As shown, the reinforced hollow wall winding pipe provided by the present invention, the winding pipe is a hollow winding pipe 1 body spirally wound outside the pipe, and its structure includes an outer layer of polyethylene layer 11, a glass fiber reinforced layer 12 and Inner polyethylene layer 13; wherein, inside the hollow winding pipe 1 is provided with a reinforced inner rib 2, and the reinforced inner rib 2 is arranged in the middle in an X shape, and the two inner ribs intersect with each other, and the extension direction is the same as that of the hollow winding Tube 1 is in the same direction.
[0041] Further, on the same horizontal line, the distance between two adjacent winding pipes is 4-8cm.
[0042] As a preferred method, an inner rib glass fiber layer is provided inside the reinforced inner rib.
[0043] The enhanced hollow wall winding pipe joint connection method provided by the present invention is constructed according to the fol...
Embodiment 2
[0065] The difference from Example 1 is that in the implementation process of the glass fiber inner rib reinforced spiral wound pipe joint connection method, the shrink tube is used for reinforcement first, and then the clamp is used to reinforce the joint. 1, it can more effectively enhance the mechanical stability of the structure.
Embodiment 3
[0067] The difference from the above two embodiments is that an inner rib glass fiber layer is added inside the inner rib, which has a stronger effect.
[0068] Such as image 3 , Figure 4 As shown, the shape of the corrugation has been further optimized, and trapezoidal or triangular shapes can be selected, as well as other winding tube shapes with simple structure but strong stability.
[0069] The hollow-wall winding pipe of the present invention is a structural wall pipe made of high-density polyethylene (HDPE) by a thermal winding molding process, which conforms to the national standard "Polyethylene (PE) Structural Wall PipingSystem for Buried Ground" No. 2 Part: "Polyethylene Wound Structural Wall Pipes" (GB / T19472.2-2004) requirements. The pipe is suitable for municipal drainage, building outdoor drainage, buried farmland drainage, industrial sewage, road drainage, sewage treatment plants, stadium square engineering drainage, electrical and telecommunications enginee...

Abstract
The invention provides a reinforced hollow wall winding pipe and a joint connecting method thereof. A winding pipe body is formed by spirally winding a hollow pipe body outside a pipe product and structurally comprises an outer polyethylene layer, a glass fiber reinforcement layer and an inner polyethylene layer from outside to inside in sequence. Inner reinforced ribs are arranged inside the winding pipe body and are further disposed in the middle of the winding pipe body in an X shape. Every two inner ribs are crossed with each other, and the extending direction is consistent with the direction of the winding pipe body. The construction method includes the following steps that first, a hollow winding pipe joint is cleaned and the end face flatness of the hollow winding pipe joint is determined; second, an electric hot melting tape is adopted for connecting the hollow winding pipe joint; and third, a retractable pipe and / or a clamp are / is adopted to conduct reinforcing construction onthe joint. The inner ribs are additionally arranged inside the hollow winding pipe body, the fusion-type joint connecting method is provided, the ring stiffness of the hollow winding pipe body can beeffectively enhanced, subsection positions are stable in structure and breakage cannot happen easily.
Description
technical field [0001] The invention belongs to the technical field of hollow-wall winding pipes used in municipal construction, in particular to an enhanced hollow-wall winding pipe and a joint connection method thereof. Background technique [0002] In the process of municipal construction, polyethylenehollow wall winding pipes are generally used for buried drainage, and its diameter is relatively large. The ring stiffness of this type of plastic buried drainage pipe can generally reach the level of SN8; and the hollow winding pipes in two segments The weak link between the pipes is easy to delaminate and crack under the action of external force, resulting in easy deformation of the pipes, reduced service life of the pipes, and potential safety hazards. Generally, regular inspections are required, and timely maintenance is required when damage is found. The cost is very high. Contents of the invention [0003] In order to solve the above technical problems, the present...
