Abstract

The present invention provides an improved manufacturing method for manufacturing pipeline push pipes. A push pipe of a plastic composite pipe, which is manufactured by the method, comprises two layers of plastic walls; one layer is provided with a porous steel band net, and the other layer is provided with glass steel; a steel plate supporting opening with an edge is installed on one end of the push pipe, and porous flat steel plates are installed on the other end; when the steel plates are connected, one flat end is inserted into the supporting opening of the other pipe; homogeneous steel plates are welded; homogeneous plastics are welded. The push pipe of the plastic composite pipe, which is manufactured by the method, obviously relieves the weight in the push pipe for convenient construction, reduces workloads, enhances working efficiency, and has the advantages of firmness, durability, long service life, low roughness coefficient of the pipe wall, fast water transportation, difficult leakage and difficult secondary pollution. The push pipe of the plastic composite pipe is mainly used for water supply, drainage, pollutant discharge, water transportation and municipal underground push pipes.

Description

The manufacture method of plastic composite pipe push pipe

The invention relates to the manufacture method of pipeline push pipe, more particularly, the invention relates to the manufacture method of band shear-steel plate, fiberglass and the compounded plastic composite pipe push pipe of plastics with plastics steel band with holes.

Background technology

The manufacture method of the manufacture method of plastic composite pipe push pipe and concrete reinforced pipe push pipe is roughly the same.The classical production process of concrete reinforced pipe push pipe is: reinforcing bar is made mesh duct put into prefabricated pipeline mould, cast concrete is wrapped in bar-mat reinforcement tubulature road and forms concrete reinforced pipe in the tube wall, after solidifying, HCS forms the concrete reinforced pipe push pipe, end at push pipe is installed the pipe box that steel plate is made, and forms the bell and spigot of concrete reinforced pipe push pipe.The other end is flat mouthful.They insert bell and spigot with an end of another root concrete reinforced pipe push pipe in the process that connects, connect through cement sand plaster.Its weak point is the push pipe Heavy Weight, frangible, life-span is short, construction is slow, water delivery is slow, tube wall easy to leak, interface cement mortar and socket joint steel plate junction easy to leak, easily causes secondary pollution.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of method of the manufacturing plastic composite pipe push pipe that has improved is provided.The advantage of utilizing the plastic composite pipe push pipe of this method manufacturing be in light weight, firm and durable, life-span long, be convenient to that construction, water delivery are fast, tube wall easy to leak not, interface through the homogeneity steel plate to welding, the butt welding of homogeneity plastics and easy to leak not.

The present invention is achieved by following technical proposals.

Plastic composite pipe push pipe of the present invention comprises plastic material, steel band with holes, fiberglass, band shear-steel plate.Described plastic composite pipe push pipe is wound in the plastic spiral winding pipe by plastic material through two helical layers, on the outer wall of plastic spiral winding pipe, be welded into and netted plastic spiral coil tightly encased, twine one deck fiberglass in plastic spiral winding pipe and steel band with holes outside again and form a flat mouthful pipeline with steel band with holes.End at flat mouthful pipeline is installed the pipeline birdsmouth of making the band sword with steel plate, the other end is then installed flat mouthful of steel plate with holes, they insert birdsmouth with a flat mouthful of end of another root plastic composite pipe push pipe in the process that connects, steel plate welding with peaceful mouthful of the steel plate of birdsmouth, mouth of pipe homogeneity plastics and homogeneity Plastic Welding, be reserved with corresponding perforation on the duct wall with this method manufacturing, in managing, whitewash when between push pipe and the original soil hole being arranged in the confession work progress, make between push pipe and the original soil and tamped by mortar by spray pump.

The present invention's advantage compared with prior art is:

1, in light weight, be convenient to construction, reduce workload, improve work efficiency;

2, sturdy and durable, long service life (reinforced concrete pipe 10-15, plastic tube is more than 50 years);

3, the tube wall coefficient of roughness low (concrete reinforced pipe is 1.8-3.5, and plastic tube is 0.008), water delivery is fast;

4, tube wall easy to leak not is difficult for causing secondary pollution;

5, joint homogeneous material butt welding, twice welding, not easy to leak.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

In the drawings; section bar Fig. 1 twines through spiral male lock (1) is stung mutually with female lock (5); female lock (2) is stung mutually with male lock (4) and is formed pipeline; again section bar Fig. 2 is put on the pipeline that Fig. 1 twines; the hero lock (6) of Fig. 2 and the female lock (3) of Fig. 1 are stung mutually; twine formation double walled pipeline through spiral; on the pipeline outer wall that Fig. 1 Fig. 2 is twined, carry out netted welding with steel band Fig. 3 with holes again; make the netted plastic tube that tightly encases; rigidity with the reinforced plastics pipe; again at plastics and netted additional layer fw frp; both can protect netted steel band and airborne oxygen isolated; can increase the rigidity of pipeline again; install (9) of the birdsmouth such as the perspective view 8 of the band sword made from steel plate then at an end of plastic composition pipeline; install steel plate with holes at the other end and form (10) of flat mouthful of pipeline as perspective view 8, (11) on the perspective view 8 are the hole of reservation, in managing pipe outer wall and soil aperture sandblast being starched the usefulness of tamping with spray pump in the construction.

In construction, flat mouthful of end insertion birdsmouth end with pipeline carries out Plastic Welding with homogeneity steel plate (10) with (9) welding with homogeneity Plastic Flat mouth connecting place with welding, forms the plastic composite pipe push pipe.

Fig. 9 is the user mode figure of plastic composite pipe push pipe, and (12) are the ground floor plastic tube walls in the drawings, and (13) are second layer plastic tube walls, and (14) are the lamina reticularises of the 3rd layer of steel band with holes, and (15) are the sandwiching glass steel.

Embodiment 1: section bar made of plastic such as Fig. 1, Fig. 2, section bar Fig. 1, Fig. 2 are wound in plastic spiral pipe through spiral winding machine, on plastic spiral pipe, weld one deck steel mesh such as perspective view 8 again with steel band Fig. 3 with holes, add in the above again and twine one deck fiberglass and make plastic composite pipe, reserve perforation on the tube wall, at the steel plate birdsmouth (9) of this Guan Yiduan mounting strap sword, the other end is installed flat mouthful steel plate, makes user mode Fig. 9 of plastic composite pipe push pipe.To put down during connection mouthful and to inject a birdsmouth, and with welding the steel plate of homogeneity be welded, the plastics that use the same method homogeneity weld.
