Abstract
A kind of plastic winding structure wall bell-and-spigot pipe comprises plastic winding structure wall straight length and the enlarging pipeline section that is connected the band bell and spigot joint of this straight length one end.Preparatory work and the installation procedure that plastic winding structure wall bell-and-spigot pipe of the present invention makes tubing that be installed early stage become simply, fast, and reduced the risk that tubing carries out occurring after the connection seepage.
Description
Technical field
The present invention relates to a kind of plastic tube, relate in particular to a kind of plastic winding structure wall bell-and-spigot pipe and preparation method thereof.
Background technique
At present, the tubing that domestic underground water supply and drainage pipe-line system is used mainly contains concrete pipe, concrete reinforced pipe and cast iron tube, because it is bigger than length and vehicle flowrate that it builds the time limit, the buried concrete waste pipe in some highway section and cast iron water pipe are damaged in succession aging, cause municipal drainage to stop up, the water pipe explosion, not only bring inconvenience to citizen's life, and because of working procedure complicated, the pipe joint number is more, leakage proof is difficult in time handling, accumulate over a long period and not only can cause road foundation to sink, effluent seepage, also can pollute soil property, the water source becomes public hazards.For this reason, adopt have good withstand voltage, light weight, corrosion-resistant, environment protection type tubing become the task of top priority.
Recent years, all types of plastic tubing rises gradually at home, and progressively replaces concrete pipe, concrete reinforced pipe and cast iron tube.With respect to concrete pipe, concrete reinforced pipe and cast iron tube, plastic tube have light weight, corrosion-resistant, the low pollution or free of contamination remarkable advantage, and plastic tube is also longer working life under identical withstand voltage condition.What plastic tube was relatively more commonly used at present is the pvc pipe material, though price is lower, it is heavier to exist quality, and withstand voltage deficiency has shortcomings such as a small amount of pollution.And the HDPE solid wall pipe, though function admirable, cost is higher, waste material.So a kind of novel plastic winding structural wall tube arises at the historic moment, it has kept the advantage of common plastics tubing, has overcome their some shortcomings simultaneously again.
But the plastic winding structural wall tube of prior art is generally straight tube, thereby has certain problem when construction, i.e. connection between the tube and tube bothers time-consuming.The Placement that adopts generally has welding at present, socket joint connects, Placements such as clip connected, these Placements all will adopt one section bell and spigot joint to be connected with straight tube, it is more loaded down with trivial details to connect the in earlier stage required preparatory work of construction at it like this, installs to connect complexity of operation, also longer during installation fee, and, also increased tubing the risk that seepage appears in the back sealing part has been installed because the construction interface is more.
Summary of the invention
Purpose of the present invention provides a kind of plastic winding structure wall bell-and-spigot pipe with new structure for the problems referred to above that overcome the prior art existence exactly.
The object of the present invention is achieved like this: a kind of plastic winding structure wall bell-and-spigot pipe comprises plastic winding structure wall straight length and the enlarging pipeline section that is connected the band bell and spigot joint of this straight length one end.
The present invention makes it compared with prior art owing to adopted above technological scheme, has following advantage and characteristics:
1, tubing is installed preparatory work in earlier stage and is significantly reduced, and has dispensed pipe fitting and has manufactured back and the supporting process of tubing.
2, the tubing connection is more convenient, in tubing connection work progress, only the tubing socket joint need be coupled together and get final product, so promptly makes things convenient for and has saved a large amount of installation times again.
3, because average per two tubing have only an interface when connecting, so just significantly reduced the risk that seepage appears in the tubing joint.
4, solved the problem that the winding structure pipe can't online enlarging.
5, solved the not inconsistent problem of creep ratio rate simultaneously of tubing and pipe fitting material.
Description of drawings
The sectional structure schematic representation of Fig. 1 plastic winding structure wall bell-and-spigot pipe of the present invention.
Embodiment
Referring to Fig. 1, a kind of plastic winding structure wall bell-and-spigot pipe of the present invention comprises plastic winding structure wall straight length 1 and the enlarging pipeline section 2 that is connected the band bell and spigot joint of this straight length one end.Be connected into integral body with shrink belt or Electric thermal smelting belt 3 fusion weld between straight length 1 and the enlarging pipeline section 2.Bell and spigot joint inwall in enlarging pipeline section 2 is provided with the seal groove 21 that a circle is used for the setting-in rubber washer.
The making method of plastic winding structure wall bell-and-spigot pipe of the present invention is at first to be made into plastic winding structural wall tube and to cut into the straight length of certain-length as the plastic winding structure wall bell-and-spigot pipe by extruding filament winding process; And produce the enlarging pipeline section of the band bell and spigot joint of plastic winding structure wall bell-and-spigot pipe with the method for moulding by casting; Again above-mentioned straight length and enlarging pipeline section are connected into integral body with shrink belt or Electric thermal smelting belt fusion weld, promptly obtain the plastic winding structure wall bell-and-spigot pipe.
Embodiment 1
By extruding the plastic winding structural wall tube that filament winding process is made into internal diameter 294mm, wall thickness 6mm, and cut into the straight tube that length is 5.95m, in addition produce the flared tube that total length is the band bell and spigot joint of 0.295m, and make its internal diameter, wall thickness identical with internal diameter, the wall thickness of aforementioned straight tube with the method for moulding by casting.Mode by the Electric thermal smelting belt welding becomes as a whole with winding structure straight tube port with flared tube interface fusion weld then.Promptly obtain a kind of plastic winding structure wall bell-and-spigot pipe of the present invention.
By extruding the plastic winding structural wall tube that filament winding process is made into internal diameter 195mm, wall thickness 5mm, and cut into the straight tube that length is 4.95m, in addition produce the flared tube that total length is the band bell and spigot joint of 0.25m, and make its internal diameter, wall thickness identical with internal diameter, the wall thickness of aforementioned straight tube with the method for moulding by casting.Mode by the shrink belt welding becomes as a whole with winding structure straight tube port with flared tube interface fusion weld then.Promptly obtain a kind of plastic winding structure wall bell-and-spigot pipe of the present invention.
Embodiment 3
By extruding the plastic winding structural wall tube that filament winding process is made into internal diameter 492mm, wall thickness 8mm, and cut into the straight tube that length is 3.95m, in addition produce the flared tube that total length is the band bell and spigot joint of 0.395m, and make its internal diameter, wall thickness identical with internal diameter, the wall thickness of aforementioned straight tube with the method for moulding by casting.Mode by the Electric thermal smelting belt welding becomes as a whole with winding structure straight tube port with flared tube interface fusion weld then.Promptly obtain a kind of plastic winding structure wall bell-and-spigot pipe of the present invention.
