Abstract

The utility model relates to a metal threaded pipe. The utility model is composed of a pipe line wall and a pipe opening, wherein, the pipe line wall is provided with an inclined bulge and a concave groove, pipe wall plates are hinged together, the bulge and the concave groove which are arranged at the point of the pipe opening are perpendicular to the axial line of a pipe, and circular holes are uniformly distributed on the pipe line wall. Pipe hoops respectively have a single hoop, double hoops, and three hoops. The utility model has the advantages of light weight, flexible, simple, and convenient connection mode, superior performance of corrosion prevention, long service life, etc. The construction quality is ensured, and the integral compressive strength is increased, and thereby, construction is still more convenient and quick.

Description

Metal threaded pipe

Technical field:

The utility model relates to a kind of metal threaded pipe, especially for the metal threaded pipeline of water supply and sewerage pipeline and underground water or the quick infiltration of surface water.

Background technique:

The most popular concrete reinforced pipe that mostly is of present subsoil drain engineering both domestic and external, cast iron tube, plastic tube generally only are used for diameter below 600MM.The concrete reinforced pipe pipe range is generally 2-3M.Interface shape mainly contains three kinds of lantern ring types, groove and tognue type, spigot and socket type.And before installation, must beat concrete foundation and base at channel bottom earlier, and must cram the interface slit with cement mortar.Its shortcoming is that tubing manufacturing process complexity, long occupied ground of manufacture cycle are big; Weight is big, and the inconvenience transportation is prone to damage, is subjected to pipeline foundation requirement height, the limited influence of pipe length, and the material cost in the installation process, cost of labour are paid bigger, make the project total cost height; The mounting process complexity, interface needs health; Interface and body deformation resistance are poor, and easily generation dislocation in the use, tubing fracture cause sewing; Tube shaped is single, has only straight tube, and pipeline turns to, reducing, along separate routes can only establish well and realize.Adopt that to lay the aqueduct that has certain slope in the desired underground degree of depth be that spiral wire infantees pipe is made aqueduct and at present infiltration fast dewatering, the face of land, but it exists that compressive strength is low, constructional difficulties, the unmanageable shortcoming of the gradient.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of metal threaded pipe, can shorten duration of a project and comprehensive cost when being used for water supply and sewerage pipeline, has improved working life and has guaranteed construction quality; Be used for to improve whole compressive strength when seep water fast in dewatering, the face of land, and make construction convenient.

The technical solution of the utility model is achieved in that a kind of metal threaded pipe, is made up of tube wall and interface, and oblique projection and groove are wherein arranged on the tube wall, and it is corrugated that section becomes, and is stranded connection between the tube wall plate; The projection at mouth of pipe place and groove are perpendicular to the tubing axis; The cross section of tubing is a star structure, and tubing mouth cross section is a round structure.Be distributed with circular hole on the tube wall equably; Circular hole directly is 10-14mm; Tubing is connected by pipe collar; Pipe collar has single, double hoop and three hoops.

Good effect of the present utility model is: a kind of metal threaded pipe, have in light weightly, and Placement is simple and direct flexibly, and antiseptic property is good, advantages such as long service life; And guaranteed construction quality; Increased whole compressive strength, made construction more convenient.

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 1;

Fig. 4 is a stranded schematic representation between the tube wall of Fig. 1;

Fig. 5 is the another kind of embodiment's of the utility model a structural representation;

Embodiment:

The utility model will be further described below in conjunction with accompanying drawing: a kind of as shown in Figure 1 metal threaded pipe, form by the tube wall 1 and the mouth of pipe 5, oblique projection 3 and groove 4 are wherein arranged on the tube wall 1, and section becomes corrugated corrugated sheet to be entwined, and edges of boards are mutually stranded to become one.As Fig. 4 is to be stranded connection between the tube wall plate; The projection 6 at the mouth of pipe 5 places and groove 7 are perpendicular to the tubing axis; Cross section as Fig. 2 tubing is a star structure.Cross section as Fig. 3 tubing mouth is a round structure.Be distributed with circular hole 8 equably on the tube wall 1 as shown in Figure 5; Pipe collar has single, double hoop and three hoops as shown in Figure 2.Get the tubing raw material and adopt two-sided 600g/m ²The galvanized sheet of attached zinc amount, adopt special-purpose metal threaded pipe processing equipment at first to process oblique projection 3 and groove 4 to tubing, the line up place processes again afterwards, makes the axis normal of the projection 6 at its mouth of pipe place and groove 7 and the mouth of pipe, matches with projection and groove on the pipe collar of Fig. 2.Pipe collar can be adjusted the quantity of pipe collar according to the pipeline of different size, when caliber connects with bushing pipe when 400mm is following, when caliber connects with the single tube hoop at 500-800mm,,, caliber connects when then using three pipe collars when 2.5m is above when caliber connects with two-tube hoop at 900mm-2.5m.Its thickness adopts the sheet material of 1.6-2.7mm, and its pipe collar can be made into different shape, as 90 ° of types ,+font, T font, 60 ° of types, Y type, 45 ° of types of 22.5 ° of types, horizontal type etc.Seep water fast when using round-meshed metal threaded pipe for reducing underground water level, the face of land as Fig. 5, because underground, surface water relies on the pressure of self to see through circular hole and by the derivation of confluxing of the natural grade of its tubing, strengthen anti-pressure ability, solved the big problem of difficulty of construction.And this tubing can also be mated formation as the disposable of large-scale tunnel.
