In the water intercepting ditch adopted in the prior art, concrete pouring is adopted on the double wall surfaces of the water intercepting ditch, the collected water flow is not filtered, and sundries in the water flow are easy to cause the situation of blocking the water intercepting ditch; according to the scheme, the lead wire gabion wall is arranged at the toe of the turf slope, when water flows through the turf slope, large-particle soil and sundries in the turf are filtered by the lead wire gabion wall, smooth collection of the water flow into the integrated curb can be ensured, a large amount of large-particle soil and sundries cannot exist in the curb, the workload of sanitation workers is large, and the working efficiency of the sanitation workers is influenced; meanwhile, the water and soil loss condition of the turf side slope is reduced.
And in this scheme, adopt the vertical height that sets up the plumb line gabion wall to be higher than the vertical height of turf side slope, can effectually avoid under the big circumstances of turf side slope discharge, the rivers directly diffuse and pass the plumb line gabion wall, cause the rivers of taking debris directly to get into integration curb.
Secondly in this scheme, still set up first reverse filtering layer in integration curb, this first reverse filtering layer carries out secondary filtering to the rivers that sink into integration curb, filters finer sand and impurity in the rivers, when guaranteeing that rivers sink into the drain pipe, can not cause the drain pipe to block up, has also guaranteed that this rivers that sink into in the river can not cause the pollution to the river.
Finally, the inclined direction of the inclined component of the integrated curb is set, so that when the flow rate of water flowing into the integrated curb is low, the water can smoothly flow into the first reverse filtering layer, and the smoothness rate of the water is ensured; the ponding in the integrated curb can not be generated, and serious influence is generated on the river landscape.

Further, the drain pipe is arranged at the bottom of the vertical component, and is obliquely arranged; the drain pipe is arranged at the bottom of the vertical component, the first reverse filtering layer covers the drain pipe, the drain pipe is well wrapped, and meanwhile, the bottom surface of the first reverse filtering layer is closely contacted with the top surface of the inclined component, and no gap exists; the water flow rate of the integrated curb is ensured to be smaller, and the integrated curb can be converged into a river through the first reverse filtering layer and the drain pipe.
Further, the inclination direction of the drain pipe is the same as the inclination direction of the turf slope 4.
Further, the drain pipe adopts a PVC pipeline with phi 5 or phi 10;
further, the number of the drain pipes is not less than 1, and the drain pipes are arranged at intervals along the river direction.
In the prior art, a drain pipe is arranged in a water interception ditch, so that when the water flow is large, water flows spread to the road surface to form accumulated water on the road surface; therefore, the adoption of the plurality of water drainage pipes in the scheme can carry out better drainage on the water flow collected into the integrated curb, the problems that the water drainage formed by only arranging one water drainage pipe in the existing water interception ditch is not smooth and can lead the water flow to the road surface and form water accumulation on the road surface are solved.
Further, the interval distance of the drain pipes is 100cm.
Further, the integrated curb adopts precast concrete; the construction cost can be reduced by adopting precast concrete, and the manufacturing is simple.
The second object of the present invention is to provide a construction method of an integrated kerbstone double-filtering drainage device, which is characterized by comprising the following steps:
