Abstract
The present invention discloses a buried plastic pipe with shaped rib. It is characterized by that on the outer wall of its pipe body a ring shaped rib is set, its horizontal direction, namely sectional area of its left and right places is greater than vertical direction, namely sectional are of its upper and lower places; or in the rib position a lining component is added.
Description
Technical field
The present invention relates to plastic tube, particularly a kind of deformed ribbed plastic buried pipe.
Background technique
Plastics are flexible materials, use the underground pipe of plastic production, must have to resist to be subjected to 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.Traditional reinforcement rib mostly 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: provide a kind of deformed ribbed plastic buried pipe, 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 rib of ring-type, and this rib is a kind of special-shaped rib; In the cross section perpendicular to described body axis of described rib, described rib is the endless belt that thickness remains unchanged; Along on the axial direction of described body, the left part width of described rib and right part width widen and all greater than its upper width and lower width.
Designer of the present invention by analysis, plastic buried pipe tube wall after being subjected to the pressure of soil can be out of shape, and produces different stress distribution in its ring-type tube wall, i.e. Guan Ding, pipe (Vertical direction) outer, end compression chord, pipe flank (substantially horizontal) outer is subjected to 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, to adapt to the different stress distribution of ring-type tube wall, especially can resist managed side tension stress influence.
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 saved 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 the fracture of pipe flank to flatten, and special-shaped plastic drain-pipe not only has big ring stiffness, the anti-ground pressure, amount of deformation of being subjected to less, and more difficultly causes 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
The invention will be further described below in conjunction with embodiment and accompanying drawing, but do 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 prior art 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: described special-shaped rib 2 is the endless belt, its left and right thickening (see figure 1).
As shown in Figure 3 and Figure 4: described 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.
As shown in Figure 5 and Figure 6: described 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 one or more than one ribs (see among Fig. 6 shown in the 2-2), and the rib that is increased links to each other with the rib of centre.
As shown in Figure 7 and Figure 8: the described 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. rationally distribute and use material, realize that the ring stiffness of enhancing ribbing plastic tube and the suffered tensile stress in outer of anti-plastic tube two flanks are 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 by 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, as 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.
