Embodiment Construction

[0028] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0029] In this embodiment, a polyethylene winding structural wall drainage pipe connection process, first prepare the following materials:

[0030] Tension device 2, such as Figure 5 As shown, the tension device is composed of a cylindrical body with a slit and an internal adjustment device. The slit is opened along the axial direction of the cylinder wall to make the cylinder elastic. The width of the cylinder must be Make sure there is enough space for welding. The adjusting device is located in the cylinder body of the half-slit position, including nut seats positioned at two ends of the half-slit, the adjusting screw rod 21 is vertically arranged with the half-slit, and the two ends of the adjusting screw mandrel 21 are respectively connected with two nut seats. Drive motor is housed on the adju...

Abstract

The invention relates to a connecting process for a polyethylene winding structured wall drainage pipe, and the connecting process is used for solving the field connection problem of a water supply and drainage plastic composite pipe. The connecting process is characterized by comprising the following steps: assembling a tension device, arranging an electric hot melt sleeve, fixing the electric hot melt sleeve with a tightening belt, regulating and tightening the tension device, and setting a welding current value and welding time. A completely sealed and non-interface water supply and drainage pipeline product is obtained by a welding mode; the auxiliaries are simple in structure, permanent pipe joint fittings are not required for supporting, and therefore, the connecting process is suitable for large-caliber pipeline connecting; the whole circle of the connected pipe orifice is once fusion-welded, so that the stress is uniform, and the ring stiffness is high; and the connecting process does not have special mounting technical requirements, is easy to operate, is high in efficiency, and is safe and reliable.

Description

technical field [0001] The invention relates to pipeline manufacturing technology, in particular to a polyethylene winding structural wall drainage pipe connection process. Background technique [0002] Polyethylene winding structural wall drainage pipes are more and more widely used in water supply and drainage projects because of their light weight, high ring stiffness, and safe and reliable connections. There are many existing pipeline connection methods, such as the patent publication number CN103115207A, a pipeline connection mechanism designed, including a connector head, with interconnected holding chambers and a first straight pipe section, the first straight pipe section is welded to one end of the pipeline; Connecting female head, with interconnected compression chamber and second straight pipe section, the second straight pipe section is welded to the other end of the pipe; installed in the holding chamber of the connecting sub-head welded on a pipe, and the seali...
