Abstract
The utility model relates to a plastic pipe having internal spiral ridges with reinforced ribs in a hollow wall. A plastic pipe wall 1 having internal spiral ridges is made into a structure of a hollow cavity 2 in which vertical reinforcing ribs 3 are uniformly fixed at interval. The utility model can thoroughly eliminate the noise generated in drainage when served as a downflow pipe. Moreover, the utility model has the advantages of low cost, and light weight, and the strength is not decreased.
Description
The utility model belongs to the improvement of plastic pipe.
The noise that the plastic pipe that existing following water is used produces when descending water in order to reduce generally all is fixed with scroll on the inwall of plastic pipe, though can reduce some noises like this, it is not thorough to control noise, and cost is also high.
The purpose of this utility model is the plastic pipe of the inside spin rib of band reinforcing rib in a kind of hollow wall of development, and this plastic pipe is done down the water time spent can thoroughly eliminate noise, and cost is also low, and intensity does not reduce again, body weight is light.
The utility model is a structure of the plastic tube wall with inside spin rib being made cavity, is fixed with vertical strengthening ribs in cavity at interval equably.
The utility model is done the sewer pipe time spent, the noise that produces in the time of can thoroughly eliminating down water, and its reason is except that the effect of inside spin rib, has hollow wall easily to absorb the effect of noise again.But also has the advantage that cost is low, intensity does not reduce, body is light.
Fig. 1 is an overall structure schematic diagram of the present utility model, and Fig. 2 is a vertical view of the present utility model.
Embodiment: present embodiment is a structure of the plastic wall 1 with inside spin rib being made cavity 2, is fixed with vertical strengthening ribs 3 in cavity 2 at interval equably.
Claims (1)
1, the plastic pipe of inside spin rib of band reinforcing rib in the hollow wall is characterized in that the plastic tube wall (1) that will have the inside spin rib makes the structure of cavity (2), and the interval is fixed with vertical strengthening ribs (3) equably in cavity (2).
