Description

Technical Field

[0001] The utility model belongs to the technical field of roadbed anti-seepage and drainage, and specifically relates to a directional drainage two-cloth-one-membrane equipment regulating device. Background Art

[0002] With the continuous improvement and development of my country's transportation system, it is extremely important to prevent and slow down the damage of the pavement system and extend the service life of the road. The main reason for the degradation and damage of the structural performance of paved and unpaved pavements such as roads, railways, airport runways, and taxiways is the attenuation of the strength of the roadbed. The intrusion of water into the roadbed significantly affects the physical and mechanical indicators of the soil. If it cannot be effectively discharged in time, it will cause a variety of roadbed diseases. Therefore, water damage is the direct cause of roadbed damage. The timely discharge of water from the roadbed is of great practical significance for slowing down the decay of the physical and mechanical properties of the roadbed and ensuring the healthy operation of railways, highways, etc.

[0003] The advantage of directional drainage two-cloth-one-membrane is that it reduces the flow distance of infiltrated water on the membrane, reduces the flow area of ​​water, speeds up the flow rate, and allows the infiltrated water to be discharged as quickly as possible. The drainage effect is obvious and it has broad application prospects in anti-seepage and drainage projects such as railway roadbeds.

[0004] Most of the highway subgrades in my country are likely to be damaged by water, so the design and application of new methods and new materials for subgrade drainage systems should be developed simultaneously with the construction of highways, railways, etc.

[0005] Chinese patent CN104863116A discloses a directional drainage two-cloth-one-membrane anti-seepage drainage structure, which discloses a layer of ribbed plastic film sandwiched between two layers of geotextiles, the direction of the ribs is perpendicular to the direction of the roadbed, and after rainwater penetrates into the ribbed plastic film, it flows downward along the membrane surface along the lateral slope of the roadbed and flows outside the anti-seepage area along the direction of the ribs, thereby reducing the water flow area, accelerating the flow rate, and allowing the seepage water to be discharged as soon as possible. This patent only optimizes the structure of two cloths and one membrane.

[0006] Chinese patent CN101942802A discloses a method for laying a sliding layer of two fabrics and one membrane and a tensioning device thereof.

This ensures the close contact of the two fabrics and one membrane, and effectively solves the bulging phenomenon of the two fabrics and one membrane before concrete pouring. This patent is designed for layer laying and improvement. Summary of the invention
