Description

Self sealss HDPE double-walled corrugated pipe

Technical Field

The utility model relates to a drainage pipe, especially a self sealss HDPE double-walled corrugated pipe.

Background

With the rapid development of urban construction, the traffic flow is rapidly increased, and the quality defects of damage, cracks, settlement and the like to the existing urban road are accelerated. At present, the peripheral backfill design of the rain and sewage drainage pipeline at the lower part of the municipal road mostly adopts filler with good water permeability to carry out manual tamping and filling, so that the soil quality is poor in compactness. The leakage at the interface of the HDPE double-wall corrugated pipe is a common quality problem in the construction of the existing municipal rainwater and sewage pipeline, so that the loss of adjacent soil is easily caused, the local settlement of a roadbed is difficult to avoid, and the dislocation of the interface of a drainage pipeline under a road structure layer can be possibly caused; cause rain in the pipeline, sewage also can outwards seepage gradually, aggravated the soil body loss of pipeline interface both sides, especially to the fill out of water permeability soil property, the influence is more obvious. The traditional restoration not only needs to destroy the surface layer and the base layer of the road, but also can involve the excavation of the roadbed, increases the environmental pollution such as noise, dust raising and the like, and easily causes traffic jam to the maintenance of drainage pipelines under main roads and secondary roads of the city, thus seriously affecting the smoothness of the urban traffic.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure, construction convenience prevents that pipeline interface seepage from sealing HDPE double-walled corrugated pipe.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme: the utility model provides a self sealss HDPE double-walled corrugated pipe, includes socket joint pipe, injection device, filler device, injection device includes seal structure and water conservancy diversion structure, seal structure encircles the interconnect department at each socket joint pipe, be equipped with the buffer between the junction of seal structure and socket joint pipe, the water conservancy diversion structure includes interconnect's first standpipe and first violently pipe, first standpipe is connected with injection device, first violently pipe is connected with the device of packing into.

Preferably, the outer side of the pipeline is provided with a pulp outlet which is uniformly arranged along the circumference and comprises two transverse holes, and the included angle of the two transverse holes is 90-120 degrees.

Preferably, the sealing structure of the injection device is annular, and the outer diameter of the sealing structure is smaller than that of the socket pipe.

Preferably, the filler device is internally provided with annular polyurethane foaming gap filler.

Preferably, the sealing structure is connected with the socket pipe through a detachable fixing device.

Preferably, the first vertical pipe and the first horizontal pipe are telescopic pipes with adjustable lengths.

Compared with the prior art, the utility model has the advantages that:

1, the strength and the deformation modulus of soil around the interface of the spigot-and-socket pipe are improved within a certain range by injecting polyurethane sealing material, and a buffer zone at the interface forms a ring to form a flexible sealing strip which plays a role of seepage prevention and leakage stoppage together with an original sealing rubber ring of the pipeline;

2, the design of the injection device and the filling device ensures that the pipeline has high construction speed, less investment equipment, low reinforcement cost and outstanding social and economic benefits.

Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

the utility model provides a self sealss HDPE double-walled corrugated pipe, includes socket joint pipe 1, injection device 2, packing device 6, injection device includes seal structure and water conservancy diversion structure, seal structure surrounds the interconnect department at each socket joint pipe, be equipped with buffer 3 between the junction of seal structure and socket joint pipe, the water conservancy diversion structure includes interconnect's first standpipe and first violently pipe, first standpipe is connected with injection device, first violently pipe is connected with the device of packing into. The outer side of the pipeline is provided with a pulp outlet which is uniformly arranged along the circumference and comprises two transverse holes, and the included angle of the two transverse holes is 90-120 degrees. The sealing structure of the injection device is made of annular flexible materials, and the outer diameter of the sealing structure is smaller than that of the socket pipe. The filler device is internally provided with an annular polyurethane foaming joint mixture. The sealing structure is connected with the socket pipe through a detachable fixing device 4, such as a buckle, a hinge lock and the like. The first vertical pipe and the first horizontal pipe are telescopic pipes with adjustable lengths, and the length can be adjusted by operating buttons as required.

During the use, pipeline interconnect to needs the installation, injection device is installed through fixing device temporarily in the junction, the grout outlet need be avoided during the installation, can be according to the length of the first standpipe of pipe erection position apart from the height control on ground and first violently pipe, carry out concrete pipeline backfill according to the design requirement and stabilize the pipe, the thickness of backfill 5 is the crooked footpath of pipeline 1/3 ~ 1/2, utilize the filler device to carry out cyclic annular polyurethane foaming gap filler and pour into, form cyclic annular solidification area in buffer. After the polyurethane foaming gap filler is injected for 24 hours, the injection device is disassembled by pulling the flow guide structure because the flow guide structure of the injection device is made of flexible materials, and the pipeline is backfilled after the disassembly is finished.

The strength and the deformation modulus of soil bodies in a certain range around the pipeline interface are improved by injecting the polyurethane sealing material, a flexible sealing strip is formed at the interface in an annular mode, and the flexible sealing strip and the original sealing rubber ring of the pipeline play roles in seepage prevention and leakage stoppage together. When the pipeline interface is because slight settlement, can effectively prevent intraductal water to the washing away of soil body on every side, also can effectively block to the outside because the infiltration that the road defect produced water, extension pipeline life reduces because the road bed that the pipeline seepage formed washes away the damage of collapsing, reduces road cost of maintenance. The method is particularly suitable for the construction of chemical building material socket pipes without concrete foundations, medium and small-diameter pipes and rain and sewage modification engineering pipes in old cities. The method has the advantages of simple and convenient operation, high construction speed, less investment equipment, low reinforcement cost and outstanding social and economic benefits.

The above description is only for the specific embodiment of the present invention, but the technical features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
