Plastic blind ditch characteristics
It has high compressive strength and good compressive strength. It is easier to damage under higher pressure than traditional blind ditch materials with low compressive strength. Cause drainage failure. The plastic blind ditch has high compressive strength and good recovery. Generally 250kP. (25T / m2) Under the pressure, the porosity of the cross section remains above 60%, and can be restored to its original state after the pressure is removed. There is no problem of drainage failure due to overload or other original solids, good flexibility, and strong ability to adapt to soil deformation
Plastic blind ditch material not only has pressure resistance, but also has good flexibility. Therefore, it can adapt to the deformation of the surrounding upper body and will not cut off the blind ditch due to overload, severe deformation of the foundation, uneven settlement, etc. It can avoid the occurrence of accidents caused by the failure of the traditional drainage ditch due to various reasons. hsyfxj2345631
The plastic blind ditch material adopts anti-aging formula, its performance is stable, and it has the characteristics of anti-ultraviolet rays, high temperature resistance and corrosion resistance. Therefore, the plastic blind ditch material can keep the structure stable and maintain the performance of water collection and drainage under water and soil for ten years.
The surface opening ratio refers to the ratio of the area and surface area of ​​the surface opening of the blind ditch material, generally expressed in%. It is an important property that reflects the water absorption capacity of blind ditch materials. Generally speaking, the greater the surface porosity, the better the water absorption performance and the less likely it is to block. If the surface opening rate is too small, it will easily silt the wall and make the water impervious. Draining rose fruit is also bad. In general, the surface porosity should be ≥85% porosity
The plastic cage type permeable pipe is a frame structure formed by the scrambling of modified polypropylene filaments. Wrap a layer of needle-punched geotextile. The muddy water is filtered into clean water through the overlying geotextile and enters the frame of the messy silk, which is discharged. The cross section of the permeable pipe can be made into various shapes according to the requirements of the project. There are mainly two kinds of rectangle and round. Its main advantages: the whole plastic structure, buried in the soil, will not rot under the irradiation of ultraviolet light, and has many characteristics such as changes in shape. Due to the limitations of its own performance and transportation conditions. In the construction process, there are many joints, and the length of each joint is generally 2-6 meters.
