At present, the drainage pipe mainly takes the drainage tasks of rainwater, sewage, farmland drainage and irrigation and the like. The drain pipe is divided into a plastic drain pipe, a Concrete Pipe (CP) and a Reinforced Concrete Pipe (RCP).

The drainage pipe is used for conveying high-pressure fluid, and in order to enhance the strength of the drainage pipe, a steel wire strip is usually arranged in the pipeline of the drainage pipe to enhance the compressive strength of the drainage pipe. However, when the drain pipe is recycled, the steel wire steel belt and the plastic pipe are adhered, so that the steel wire steel belt and the plastic pipe are difficult to separate, and the recycling cost of the drain pipe is high. Secondly, set up the steel wire strip in the drain pipe, can influence the ductility of drain pipe, influence the ability of drain pipe plastic deformation promptly.

In order to improve the problem, as in chinese patent, the publication number is: the CN201014074Y plastic rib pipe comprises a pipe body and a fiber net arranged in the pipe body, wherein a spiral reinforcing rib connected with the pipe body into a whole is arranged outside the pipe body, and the spiral reinforcing rib is a plastic spiral rib and is tightly connected with the outer wall of the pipe body through thermal compounding. Compare with the drain pipe that is equipped with traditional steel wire steel band, this patent has reduced the proportion of body to elasticity is good, and is difficult for the flexural flat, and abrasion strength is big, long service life. However, the compressive strength of the plastic rib pipe still needs to be improved, and secondly, when a certain position of the plastic rib is broken, the strength of the pipe body at the broken position of the plastic rib is affected, so that the compressive capacity of the pipe body at the broken position of the plastic rib is weakened, and the broken position of the plastic rib of the pipe body is broken.

The principle and the beneficial effects of the invention are as follows: (1) among the prior art, the muscle pipe of moulding that adopts is solid construction, when moulding the muscle pipe and breaking, moulds the cracked position of muscle pipe and can lose the support capacity to the body, then reduces the compressive capacity of body, moulds the cracked position of muscle pipe on the body, and the pressure effect that this position body received can strengthen, and then the body is moulding the cracked position of muscle pipe and taking place to break easily, finally leads to the unable use of drain pipe. In this scheme, at the outer tube of the spiral of body thermal compound connection, the lateral wall of keeping away from the body when the outer tube breaks, and the lateral wall that is close to the body does not break, still supports the body, has guaranteed the compressive capacity of drain pipe, and then has reduced the probability that the drain pipe takes place to break.

(2) In this scheme, be provided with the stay tube that can move about in the outer tube of spiral, because the stay tube can move about in the outer tube, when the outer tube received the impact effect and acts on, the stay tube supported the outer tube to the effort that the outer tube received can be cushioned to the stay tube, reduces the cracked probability of outer tube, and then guarantees the support intensity of body, and simultaneously, the stay tube continues to support the cracked position of outer tube, further guarantees the compressive strength of body.

(3) In this scheme, when the outer tube received the extrusion force, deformation took place for the outer tube, and then the outer tube extrusion stay tube takes place the activity in the outer tube, and when receiving the extrusion force, the stay tube can consume the extrusion kinetic energy that receives at my outer tube internalization, and then reduces the extrusion force that the outer tube received, further reduces the cracked probability of outer tube.

Furthermore, a movable filling layer is filled between the supporting tube and the outer tube.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the pipe comprises a pipe body 1, an outer layer 11, an inner layer 12, an outer pipe 2, a support pipe 21, a filling layer 22, an outer pipe inner wall 23 and an outer pipe outer wall 24.

The first embodiment is as follows:

as shown in fig. 1 and 2, a high-strength drain pipe includes a pipe body 1, the pipe body 1 includes an inner layer 12 and an outer layer 11, the inner layer 12 is thermally combined on the inner wall of the outer layer 11, the inner layer 12 is made of fiber net, and a corrosion-resistant layer (not shown) is coated between the fiber net and the inner wall of the outer layer 11, the corrosion-resistant layer is made of corrosion-resistant paint, for example: the outer layer 11 of the Teflon coating is made of PE material.

The pipe body 1 is thermally compounded with an outer pipe 2 which is spirally arranged, the outer pipe 2 is made of PE materials, a plurality of movable supporting pipes 21 are arranged in the outer pipe 2, namely a certain gap is reserved between each supporting pipe 21 and the outer pipe 2, the number of the supporting pipes 21 is two in the embodiment, and air is filled between the outer pipe 2 and the supporting pipes 21. When the outer tube 2 is squeezed, the supporting tube 21 moves in the outer tube 2 under the squeezing action of the outer tube 2, so that the energy of the squeezing force applied to the outer tube 2 is consumed, and the supporting tube 21 buffers the squeezing force applied to the outer tube 2, thereby reducing the probability of the outer tube 2 being squeezed and broken.

Example two:

the second embodiment is different from the first embodiment in that, as shown in fig. 1 and fig. 2, a movable filling layer 22 is filled between the outer tube 2 and the support tube 21, and the filling layer 22 is made of a granular PE material. The specific installation method is as follows: the outer tube 2 is thermally compounded on the outer wall of the outer layer 11, the side wall of the outer tube 2 thermally compounded with the outer wall of the outer layer 11 is an outer tube inner wall 23, and the side wall of the outer tube 2 away from the outer layer 11 is an outer tube outer wall 24. The support pipe 21 is extended into the outer pipe 2 and the support pipe 21 is arranged in a spiral direction of the outer pipe 2, and then the granular PE material is filled between the outer pipe 2 and the support pipe 21 to form the filling layer 22. The filling layer 22 formed by filling the granular PE material into the outer tube 2 disperses the extrusion force when the outer tube 2 is subjected to the extrusion force, and at the same time, when the outer tube 2 extrudes the support tube 2, the filling layer 22 does not affect the movement of the support tube 21, and the support tube 21 is used to further consume the extrusion force applied to the outer tube 21, so as to achieve the purpose of buffering the outer tube 2.

The specific implementation process is as follows:

when transporting high-pressure solution through the drain pipe, the corrosion-resistant layer protects the inner wall of drain pipe, reduces the probability that the drain pipe inner wall is corroded. The fibre web carries out certain adhesion to the drain pipe, if the drain pipe takes place certain fracture, the fibre web avoids cracked drain pipe in disorder everywhere.

In this embodiment, the outer tube 2, the filling layer 22, and the support tube 21 are filled with air, and the outer tube 2, the filling layer 22, and the support tube 21 support the tube body 1, so that the compressive strength of the tube body 1 can be enhanced. Because the outer pipe 2 and the filling layer 22 are both made of PE materials, the PE materials have corrosion resistance, and the breakage of the outer pipe 2 and the filling layer 22 caused by corrosion is reduced; on the other hand, if the outer tube 2 is impacted, the filling layer 22 and the supporting tube 21 both buffer the outer tube 2, so as to reduce the probability of breakage, and when the outer tube 2 is broken at a certain position or positions, the supporting tube 21 still breaks at the outer tube 2 to support the tube body 1, so as to ensure the compressive strength of the tube body 1.

In this embodiment, the outer tube 2 is broken, generally the outer wall 24 is broken, the inner wall 23 is always on the tube body 1, the outer wall 24 still actually supports the tube body 1, although the supporting function is reduced, because the outer wall 24 is always on the tube body 1, the breakage probability of the tube body 1 is reduced. The support tube 21 and the filling layer 22 also maintain a supporting effect on the tubular body 1 on the inner wall 23 of the outer tube. Because the filling layer 22 and the support tube 21 are arranged in the outer tube 2, the filling layer 22 and the support tube 21 can also enhance the strength of the outer tube 2, and the filling layer 22, the support tube 21 and the outer tube 2 are made of PE materials and have certain ductility, so that the ductility of the tube body 1 is less influenced.

Example three:

the third embodiment is different from the first embodiment in that three support pipes 21 are installed in the outer pipe 2, and the three support pipes 21 form a triangular structure, as shown in fig. 3. The specific installation mode is as follows: firstly, two support pipes 21 are inserted close to the inner wall of the outer pipe 2 close to the pipe body 1, then one support pipe 21 is inserted to be positioned at the upper parts of the other two support pipes 21, and then the granular PE material is filled in the outer pipe 2, and the granular PE material forms a filling layer 22.

In this embodiment, the three triangular support tubes 21 support the outer tube 2, so that the outer tube 2 has an increased pressure resistance, and the probability of deformation or breakage of the outer tube 2 is reduced when the outer tube is impacted. Thereby, the outer tube 2 has a reduced chance of breakage and the compressive strength of the tube body 1 is increased. Compared with the first embodiment, after the outer tube 2 is broken away from the outer wall of the tube body 1, the three support tubes 21 and the filling layer 22 can also maintain the support capability of the tube body 1, so as to ensure the pressure resistance capability of the tube body 1. Meanwhile, when the supporting tube 21 is acted by force, the filling layer 22 can buffer the supporting tube 21, so that the probability of breakage of the supporting tube 21 is reduced.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make several variations and modifications without departing from the concept of the present invention, and these should be considered as the protection scope of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent. The techniques, shapes, and structural parts, which are omitted from the description of the present invention, are all known techniques.
