Abstract

The invention relates to a plastic underground reinforcement pipe. In the invention, a deformed rib (2) is arranged on the outer wall of a pipe body, and the deformed rib is an annular band in a cross section vertical to the axis of the pipe body; and more than one rib is respectively and additionally added at two sides of the deformed rib along the axial direction of the pipe body and connected with the middle rib. The invention can reduce the breakage phenomenon of the plastic underground pipe so as to prolong the service life of the plastic underground pipe; materials used at the pipe top and the pipe bottom are fewer than the material of the ribs at both sides of the pipe, so that material can be used reasonably, and more than 10-30 percent of materials can be saved; the plastic underground drain pipe with larger ring stiffness (larger than 12 KN/m<2>) is not easy to deform in a construction process, thus water seepage hardly can be caused by deformation. The invention not only has larger ring stiffness, soil pressure resistance and small deformation, but also is not easy to cause pipe side breakage and flattening by pressing, thus the construction quality of the plastic underground pipe can be improved.

Description

Plastic underground reinforcement pipe

Technical field

The present invention relates to plastic tube, particularly a kind of plastic underground reinforcement pipe.The present invention is " deformed ribbed plastic buried pipe " (number of patent application: 200710051540.2; Dividing an application February 13 2007 patent application day).

Background technique

Plastics are flexible materials, with the underground pipe of plastic production, must have and anti-receive the performance of ground pressure promptly to have ring stiffness.In order to improve the ring stiffness of plastic tube, the reinforcement rib is set evenly on outer surface of tube wall.Ribbing plastic tube in the market is exactly like this.Mostly traditional reinforcement rib is annular and convex tendon that be even shape, and easy deformation exceeds standard in burying the ground using process, even damaged, influences its working life.

Summary of the invention

Technical problem to be solved by this invention is: a kind of plastic underground reinforcement pipe is provided, to overcome the defective that existing plastic buried pipe exists.

The technological scheme that the present invention solves its technical problem employing is: the outer wall of its body is provided with the special-shaped rib of ring-type, the section area that the section area that its substantially horizontal is located is promptly promptly located up and down greater than Vertical direction; Perhaps add and assist part at the rib place.

Designer's process of the present invention is analyzed, and plastic buried pipe tube wall after receiving the pressure of soil can be out of shape, and produces the different stress distribution of dirt in its ring-type tube wall, and promptly Guan Ding, pipe (Vertical direction) outer, end compression chord are managed flank (substantially horizontal) outer and received tensile stress.For this reason, the present invention designs a kind of special-shaped rib and buries the ground plastic tube, is distributed with some the ribs with special-shaped shape on its tube wall, is managed the influence that side receives tensile stress to adapt to the different stress distribution of ring-type tube wall, especially can resist.

The rib that the abnormity rib buries the ground plastic tube will lack with respect to the employed material of rib of pipe two flanks in Guan Ding, pipe bottom, has been about to steel and has used on the blade.And common ribbing to bury at the bottom of the rib cross section, Guan Ding, pipe of ground plastic tube and manage two flanks all be constant.If produce the ribbing plastic tube of same ring stiffness, special-shaped rib materials will be practiced thrift more than 10～30%.

Make special-shaped rib and bury the ground plastic tube and can have the more common higher ring stiffness of ribbed plastic buried pipe that adds, have big ring stiffness (as greater than 12KN/m ²More than) bury the ground plastic drain-pipe, not yielding in work progress, also be difficult for causing and leak by distortion.At present; Extensively there is the problem of distortion in plastic tube in the buried drain pipe engineering; Amount of deformation too greatly also can cause and leaks; Even cause pipe flank fracture to flatten, and special-shaped plastic drain-pipe not only has big ring stiffness, the anti-ground pressure, amount of deformation of receiving less, and more is difficult for causing that by pressurized the fracture of pipe flank flattens.So burying the use of ground plastic tube, special-shaped rib can improve the construction quality of burying the ground plastic drain-pipe.

Embodiment

Below in conjunction with embodiment and accompanying drawing the present invention is described further, but does not limit the present invention.

Deformed ribbed plastic buried pipe provided by the invention, the outer wall of its body 1 are provided with the special-shaped rib 2 of ring-type, its same existing technology that distributes, just: the section area that the section area that substantially horizontal is located is promptly promptly located up and down greater than Vertical direction; Perhaps, part 3 is assisted in interpolation at the rib place.

The rib of deformed ribbed plastic pipe of the present invention designs according to the different stress distribution of tube wall, is exemplified below:

As depicted in figs. 1 and 2: said special-shaped rib 2 is the endless belt, its left and right thickening (see figure 1).

Like Fig. 3 and shown in Figure 4: said special-shaped rib 2 is the endless belt, and (see among Fig. 4 shown in the 2-1) widened at its left and right place.

Like Fig. 5 and shown in Figure 6: said special-shaped rib 2 is the endless belt, and according to actual conditions, its left and right place respectively increases the quantity of rib, for example add rib more than one or one (see among Fig. 6 shown in the 2-2), and the rib that is increased links to each other with the rib of centre.

Like Fig. 7 and shown in Figure 8: the said part 3 of assisting is coated in the rib, or embedding is connected in the rib; This rib is meant the special-shaped rib 2 in the present embodiment, also can be traditional rib.This material of assisting part can be iron or engineering plastics.

Deformed ribbed plastic buried pipe provided by the invention adds ribbed plastic buried pipe with tradition to be had following different:

1. bury the ground mounting type: see Fig. 9, the rib at the Guan Ding of deformed ribbed plastic buried pipe body 1, the pipe end, pipe flank place is different (seeing vertical direction of arrow indication), and the rib of pipe flank must be placed in the horizontal direction (seeing lateral arrows direction indication).Add ribbed plastic buried pipe different (see figure 10)s when installing with tradition, sequence number 5 is traditional ribs with burying.Sequence number 4 among Fig. 9 and Figure 10 is that the groove of buried pipeline is installed.

2. the materials used that rationally distributes realizes strengthening the ring stiffness of ribbing plastic tube and the suffered tensile stress in outer of anti-plastic tube two flanks is major characters of the present invention.Design rib in the following manner:

(1) increases the material consumption of managing the flank rib, promptly add the section area of bassoon flank rib.Add bassoon flank rib section area and can see Fig. 5, Fig. 6 through increasing the bar number of flank rib; Perhaps increase the width of flank rib, see Fig. 3, Fig. 4; Or the height (thickness) of increase flank rib, see Fig. 1, Fig. 2.

(2) set up at flank rib place and assist part 3, see Fig. 7, Fig. 8.The material of assisting part is a high-strength material, like plastics, glass fibre reinforced plastics or the iron and steel etc. of high-intensity performance.Assist part and can embed the back sealing of rib seam, or prefabricated being placed in the mould, injection moulding (resemble casting reinforced concrete, it is the same to place reinforcing bar earlier).

Deformed ribbed plastic buried pipe provided by the invention is as the purposes in the waste pipe of cities and towns, or as the purposes in oil transportation, the pneumatic tube, can also be as the purposes in other field.
