Description

Technical Field

[0001] This utility model relates to the field of MPP pipe technology, specifically an MPP pipe with a built-in protective layer. Background Technology

[0002] MPP pipe, also known as MPP power cable protection pipe, is divided into open-cut and trenchless types. MPP trenchless pipe is also called MPP jacking pipe or drag pipe. MPP pipe uses modified polypropylene as the main raw material and has the characteristics of high temperature resistance and external pressure resistance. It is suitable for medium and low voltage power transmission cable ducts below 10KV. MPP pipe is generally set as single-layer or double-layer pipe and can be widely used in municipal, telecommunications, power, gas, tap water and heating pipeline projects.

[0003] Current MPP pipes are easily damaged by impacts and compression during use, and the pressure is transmitted to the inside, causing damage to the pipe and affecting the normal operation of the internal cables, thus greatly reducing the performance of the pipe. Therefore, those skilled in the art have provided an MPP pipe with a built-in protective layer to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an MPP pipe with a built-in protective layer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An MPP pipe with a built-in protective layer includes a PPM round pipe, which includes an inner pipe, a heat-conducting layer, a waterproof layer, a rubber layer, a reinforcing layer, several buffer columns, and an outer pipe. The front end of the PPM round pipe is provided with a ring-shaped arrangement of positioning grooves, and the rear end of the PPM round pipe is provided with a ring-shaped arrangement of positioning rods.

[0007] As a further embodiment of this utility model: the outer surface of the inner tube is connected to the heat-conducting layer, and the outer surface of the heat-conducting layer is connected to the waterproof layer.

[0008] As a further embodiment of this utility model: the outer surface of the waterproof layer is connected to the rubber layer, and the outer surface of the rubber layer is connected to the reinforcing layer.

[0009] As a further improvement of this utility model: the end of each buffer column near the inner tube is connected to the reinforcing layer, and the end of each buffer column away from the inner tube is connected to the outer tube.

[0010] As a further improvement of this utility model: the outer tube is corrugated, and the reinforcing layer is made of woven glass fibers.

[0011] As a further improvement of this utility model: each of the positioning rods is adapted to the positioning groove, and each of the buffer posts is made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This MPP pipe with a built-in protective layer, through the combination of buffer columns, outer pipe, reinforcing layer and rubber layer, not only greatly increases the strength of the PPM round pipe, but also improves the buffering effect of the pipe, thereby greatly increasing the service life of the PPM round pipe. The setting of positioning groove, positioning rod and waterproof layer not only makes it easy for people to splice the PPM round pipe, thereby greatly increasing the construction efficiency of the PPM round pipe, but also makes the PPM round pipe waterproof. The setting of heat-conducting layer can absorb the heat generated by the internal cable of the PPM round pipe. Attached Figure Description

[0019] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figures 1-4 In this embodiment of the present invention, an MPP pipe with a built-in protective layer includes a PPM round pipe 1. The PPM round pipe 1 includes an inner pipe 101, a heat-conducting layer 102, a waterproof layer 103, a rubber layer 104, a reinforcing layer 105, several buffer columns 106, and an outer pipe 107. The front end of the PPM round pipe 1 is provided with a ring-shaped positioning groove 2, and the rear end of the PPM round pipe 1 is installed with a ring-shaped positioning rod 3. This not only effectively protects the PPM round pipe 1, but also facilitates the splicing of the PPM round pipe 1, thereby greatly increasing the construction efficiency of the PPM round pipe 1. This solves the problem mentioned in the background art that current MPP pipes are easily damaged by collisions and compression during use, and the pressure is transmitted to the inside, thus affecting the normal operation of the internal cables and greatly reducing the performance of the pipe.

[0022] The outer surface of the inner tube 101 is connected to the heat-conducting layer 102, the outer surface of the heat-conducting layer 102 is connected to the waterproof layer 103, the outer surface of the waterproof layer 103 is connected to the rubber layer 104, and the outer surface of the rubber layer 104 is connected to the reinforcing layer 105. This not only makes the PPM round tube 1 waterproof, but also allows the heat of the cable inside the PPM round tube 1 to be absorbed, thereby greatly increasing the transmission effect of the cable.

[0023] Each buffer post 106 is connected to the reinforcing layer 105 at the end closest to the inner tube 101, and to the outer tube 107 at the end furthest from the inner tube 101. The outer tube 107 is corrugated, and the reinforcing layer 105 is made of woven glass fiber. Each positioning rod 3 is adapted to the positioning groove 2. Each buffer post 106 is made of rubber, which can prevent damage to the PPM round tube 1 from collisions, compression and stretching, thereby greatly increasing the service life of the PPM round tube 1.

[0024] The working principle of this utility model is as follows: First, during the construction of the PPM round tube 1, people can install the positioning rod 3 into the positioning groove 2 in sequence. The buffer column 106 and the rubber layer 104 can prevent the impact force generated when people accidentally step on or collide with the PPM round tube 1 during the construction process, and prevent the impact force and squeezing force from damaging the PPM round tube 1. The reinforcing layer 105 can prevent the PPM round tube 1 from breaking when it is stretched during the construction process.
