Description

Composite rubber drainage geotextile capable of directionally guiding water

Technical Field

The utility model belongs to the technical field of geotextile, and particularly relates to composite rubber drainage geotextile capable of directionally guiding water, which is particularly suitable for roadbed waterproof engineering.

Background

In recent years, with the continuous expansion of the infrastructure construction scale of China, the road network construction is rapidly developed and continuously improved, and the prevention and the alleviation of the damage of a road surface system and the prolonging of the service life of a road are of great importance. However, the vast width of our country has various climatic environments, and in rainy areas and seasonally frozen soil areas, the roadbed is extremely easy to be damaged by water, especially after heavy rainfall occurs, excessive water enters roads, including railway roadbeds, airport runways and other scenes, and paved and unpaved road surfaces of the roads are affected by permeation in different degrees, so that the physical and mechanical indexes of soil bodies are reduced, the strength of the roadbed is obviously attenuated, and the structural performance of the road surfaces is reduced and damaged; and moisture can not be effectively discharged in time, various roadbed diseases can be caused, and even roadbed collapse, road intersection and other problems can be caused, so that traffic transportation and life and property safety of people are seriously influenced.

The method aims at the problem that most of roadbeds are likely to cause water body damage, and is the most critical in the design of roadbed waterproof and drainage. At present, geotextile materials are mainly adopted in China, but the drainage capacity of geotextile in a road system is relatively limited, only when the soil body of a roadbed is in a water saturation state, a drainage channel can be formed by gravity, most of the roadbed is in an unsaturated state, and at the moment, the geotextile materials are adopted, so that the water permeation can be caused, and the strength of the roadbed is influenced; meanwhile, the geotextile has poor drainage effect, directional water diversion cannot be realized, the water body in the roadbed overflows everywhere, and only partial water can be guided to be discharged, and all water cannot be discharged quickly and effectively, so that great potential safety hazards still exist in the use process.

Secondly, the geotextile commonly used at present has single structure, low tensile strength and deformation resistance, short service life, and needs to be padded with upper and lower yellow sand layers as protective layers during construction and then laid with ballast. The standard operation is difficult to ensure in the construction process, and the geotextile is punctured by the stone ballast and loses the waterproof function because the sand ballast is often mixed.

The utility model provides a new substitute material, namely a directional water guide composite rubber drainage cloth, which can effectively prevent water from permeating, block water and guide out directionally, has higher strength, effectively avoids bursting, piercing and crushing, prolongs the service life of a road and avoids the damage of the roadbed. .
