Abstract

The invention relates to a a municipal drainage pipeline machining die and method. The die comprises a lower die, first flanges, an upper die, second flanges, a lining pipe, positioning rods and sealing plates. A grouting hole is formed in the side wall of the lower die. The first flanges are fixed to the two ends of the lower die, and first bolt holes are formed in the first flanges. An exhaust hole is formed in the side wall of the upper die. The second flanges are fixed to the two ends of the upper die, and second bolt holes are formed in the second flanges. The lining pipe is used for being installed between the lower die and the upper die. The multiple positioning rods are all located in the lining pipe. The two sets of sealing plates are located at the two ends of the lower die and the two ends of the lower die correspondingly, multiple mounting holes are formed in the sealing plates, and when the lower die and the upper die are buckled, the axes of the first bolt holes and the axes of the second bolt holes coincide with the axes of the mounting holes. Multiple positioning holes are formed in the sealing plates, and the two ends of the positioning rods can penetrate through the positioning holes correspondingly. According to the municipal drainage pipeline machining die and method, rapid machining and forming of a composite pipeline can be achieved, and the effect high forming quality is achieved.

Description

technical field

[0001] The present application relates to the technical field of drainage pipes, in particular to a mold for processing municipal drainage pipes and a processing method. Background technique

[0002] Municipal drainage pipes are used to transport and discharge domestic sewage, industrial wastewater, and rainwater, so their anti-seepage and anti-crack performance is an important indicator for evaluating their quality.

[0003] At present, municipal drainage pipes can be divided into concrete pipes, steel pipes, PVC pipes, etc. according to their different materials. Steel pipes have high strength and strong anti-seepage and anti-crack performance, but they have the disadvantage of high cost; PVC pipes have strong anti-seepage and anti-crack performance, smooth inner wall and good water-permeability, but have the disadvantage of low strength and are not suitable for deep burial; concrete pipes are the most suitable for deep burial. A wide range of drainage pip...
