Abstract
The utility model discloses a high-density polyethylene (HDPE) trenchless pipe which comprises a round pipe body, wherein the pipe body is made of high-density polyethylene materials and is 18.7 mm thick. The diameter of the outer wall of the pipe body is 315 mm. Compared with the prior art, made of the high-density polyethylene materials, the trenchless pipe has higher flexibility and a good corrosion prevention function so that corrosion on lines can be prevented. Moreover, compared with the prior art, when the trenchless pipe is used, soil engineering construction on ground, excavation of pipe lines and line burying are not needed, and the trenchless pipe can be laid inside a passageway through methods such as guiding and directional drilling on the condition that a very small part of a ground surface (generally referring to excavation of a small area of an entrance or an exit) is excavated, thereby being labor-saving and time-saving. Moreover, due to the fact that the thickness of the pipe body is 18.7 mm and the diameter of the outer wall of the pipe body is 315 mm, the trenchless pipe is enabled to have good pressure resistant ability, and therefore soil engineering construction depth can be lower.
Description
Technical field
The utility model relates to the pipeline construction field, relates in particular to the underground pipeline field that is embedded in.
Background technique
The conventional line construction need be carried out geotechnique's construction on ground, digs out the pipeline circuit, sunkens cord afterwards.Not only complicated operation is time-consuming, and corrosion resistance and pipeline anti-pressure ability are relatively poor.
The model utility content
In view of this, the utility model technical problem to be solved is: the non-excavation pipe of HDPE that a kind of saving of work and time is provided.
In order to achieve the above object, the utility model adopts following technological scheme to realize:
The non-excavation pipe of a kind of HDPE comprises circular body, and wherein, said body is the high density polyethylene (HDPE) material, and said body thickness is 18.7mm, and said tube wall diameter is 315mm.
As preferably, the end of said body has the end connecting end, and the afterbody of said body has the afterbody connecting end, and the adaptive cover of clamping each other of said end connecting end and afterbody connecting end is solid.
As preferably, said body is a bellows.
As preferably, also be bonded with buffer layer on the said inboard wall of tube body.
Can know that by technique scheme the beneficial effect of the utility model is:
Compare existing technology, the utility model makes non-excavation pipe itself have higher flexibility and anti-corrosion function through adopting the high density polyethylene (HDPE) material; Can prevent to corrode circuit, and, need not to carry out the geotechnique and construct on ground with respect to existing technology; Dig out the pipeline circuit, sunken cord afterwards, only need through means such as guiding, directional drillings; Under the situation of the minimum part excavation in the face of land, (refer generally to entrance and exit small size excavation), in passage, lay non-excavation pipe then, therefore; Unusual saving of work and time, and, be that 18.7mm, tube wall diameter are the size of 315mm through adopting body thickness; Make non-excavation pipe have better anti-pressure ability, thereby the digging degree of depth can be lower.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
In order to make those skilled in the art can further understand the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing about the utility model.
See also shown in Figure 1ly, the utility model provides a kind of HDPE non-excavation pipe, comprises circular body 1, and wherein, said body 1 is the high density polyethylene (HDPE) material, and said body thickness is 18.7mm, and said tube wall diameter is 315mm.Wherein, high density polyethylene (HDPE) (HDPE) is high, the nonpolar thermoplastic resin of a kind of known degree of crystallinity, but is not applied to the tubing field always.
Wherein, The end of said body can have end connecting end (not shown); The afterbody of said body has afterbody connecting end (not shown); The adaptive cover of clamping each other of said end connecting end and afterbody connecting end is solid, and this structural design is that adjacent two non-excavation pipes can be pegged graft easily to overlap and are solidly connected for when adopting many non-excavation pipes to carry out operation.Preferably, said body can be bellows, can further improve the intensity of body, and it also can be the body of common light face certainly, does not add qualification at this.Can also be bonded with buffer layer 2 on the said inboard wall of tube body, it can be under the bigger situation of pressure, and further the circuit in the protective tube is not extruded.
But the preferable possible embodiments that the above is merely the utility model is not the claim in order to limitation the utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, all in like manner is included in the scope of the utility model.
Claims (4)
1. the non-excavation pipe of HDPE comprises circular body, it is characterized in that said body is the high density polyethylene (HDPE) material, and said body thickness is 18.7mm, and said tube wall diameter is 315mm.
