Embodiment 1

[0034] A method for manufacturing a corrugated reinforced drainage pipe 1, comprising the following steps:

[0035] S1. A spirally wound corrugated reinforced drainage pipe 1 is formed by a spiral winding process, and the corrugated reinforced drainage pipe 1 is transported by rotating traction; the spiral winding process is a conventional forming process of the corrugated reinforced drainage pipe 1 at present, including the following two forming forms:

[0036] The specific method of forming the spirally wound corrugated reinforced drainpipe 1 by the spiral winding process in the step S1 is to form a strip-shaped section material by spiral winding and overlapping, and the section material not only includes the shape of the reinforcement layer, but also includes the shape of the formed inner pipe. pipe wall, such as Figure 5 as shown, Figure 5 The lower wall of the profile is helically wound to form the inner tube, while the upper two quarter circles form a reinforcement la...

Embodiment 2

[0045] Such as figure 1 with figure 2 As shown, a connection structure of a corrugated reinforced drainage pipe 1 is used to connect two corrugated reinforced drainage pipes 1 manufactured by the manufacturing method of a corrugated reinforced drainage pipe 1 described above. The connection structure includes connecting The pipe fitting 2, the two ends of the connecting pipe fitting 2 are respectively provided with socket holes, and the socket section 11 of the corrugated reinforced drainage pipe 1 is inserted into the corresponding socket hole and sealed with the socket hole. Wherein, the socket section 11 is provided with a placement groove 13, and a sealing ring is provided in the placement groove 13, and the sealing ring seals the socket section 11 and the socket hole. The sealing ring can be an O-ring or other sealing rings. The socket section 11 includes an inner tube layer, and a heat-shrinkable tape layer is wrapped around the inner tube layer.

Embodiment 3

[0047] Such as image 3 with Figure 4As shown, the structure of this embodiment is basically the same as that of Embodiment 2, except that the structure of the connecting pipe 2 is different from that of Embodiment 2. The middle part of the connecting pipe 2 is provided with an annular step 21, and the annular step 21 is connected to the socket section 11. sealing fit between the ends. The sealing fit between the annular step 21 and the end of the socket section 11 is as follows: the end of the socket section 11 or the end surface of the annular step 21 is provided with a mounting groove 22, and the installation groove 22 is installed with sealing ring. Preferably, the installation groove 22 is provided on the end surface of the annular step 21 .

[0048] Since the drainage pipe plays a drainage role, it only needs to withstand external pressure but not internal pressure. Therefore, it is only necessary to seal the connection between the pipe fitting 2 and the socket secti...

Abstract

The invention discloses a manufacturing method of a corrugated reinforced drain pipe. The manufacturing method comprises the following steps that S1, the corrugated reinforced drain pipe is formed through a spiral winding process and spirally pulled; S2, a first milling cutter moves at the same speed and in the same direction along with the corrugated reinforced drain pipe to mill off a reinforcing layer to form a circular pipe section; S3, the circular pipe section is thickened; S4, cooling is conducted through a cooling system; S5, the peripheral surface of the thickened circular pipe section is trimmed through a second milling cutter which moves at the same speed and in the same direction along with the corrugated reinforced drain pipe; S6, the circular pipe section is equally cut; andS7, the steps S2 to S6 are repeated, and thus the corrugated reinforced drain pipe with socket sections at the two ends is formed. In addition, the invention discloses a connecting structure of the corrugated reinforced drain pipe. The connecting structure is used for connecting drain pipes. According to the manufacturing method, the drain pipes with the socket sections at the two ends can be produced on a production line of the corrugated reinforced drain pipe, and field connection is facilitated.

Description

technical field [0001] The invention relates to a manufacturing method and connection structure of a corrugated reinforced drainage pipe, which is used for manufacturing the corrugated reinforced drainage pipe and for connecting two corrugated reinforced drainage pipes. Background technique [0002] The current corrugated reinforced drainage pipe is a composite pipe with a corrugated reinforced layer on the outside. The commonly used connection method for this type of pipe is heat shrinkable tape / electric fusion tape welding. The connection method of the heat-shrinkable tape is to heat and wind the strip-shaped heat-shrinkable tape around the ends of the two drain pipes. However, the on-site construction of this connection method is complicated, the construction is difficult, and special equipment is required for construction, which increases the cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for...
