Problems solved by technology
[0004] The core body of the gravel blind ditch on the edge of the current road surface has the following four major disadvantages: 1. The structure is huge and the construction is troublesome; The core body breaks down and breaks down, so that the drainage water body will be quickly damaged and blocked, and the drainage effect will be lost
3. It is greatly affected by construction factors, especially when cement is used to treat graded gravel, if the construction is a little careless, it will easily cause blockage. Seepage is blocked inside the road surface; 4. The drainage efficiency is low. The seepage of the pavement structure is still in the state of seepage water in the core of the vertical drainage water body, the water flow is slow, and the drainage efficiency is low.
[0005] Therefore, the current vertical drainage water body core at the edge of the pavement has a huge structure, troublesome construction, easy to block, low drainage efficiency, and negative effects in many cases

Embodiment Construction
[0034] Such as figure 2 , image 3 As shown, the core body of the longitudinal drainage water body at the edge of the road surface in the present embodiment 1 is composed of a base surface 3 and a support surface 2, and the support surface 2 is perpendicular to the base surface 3. The base surface of the present embodiment 1 is a plane plate, and the plane plate is made of plastic Made of PVC, the support surface 2 is a "T"-shaped continuous PVC board, and the "T"-shaped PVC board can also be divided into a vertical surface 21 and a plane 22, wherein the plane 22 is welded in the middle of the base surface 1 to stabilize The effect of the vertical surface 21, the vertical surface 21 plays the purpose of supporting the outer permeable filter layer; for the sake of clarity, the decomposition of the present embodiment 1 shows the permeable filter layer 1, and the vertical seepage water body core body at the edge of the road does not include the permeable filter. layer 1, but th...

The longitudinal road side penetrating drainage body features that it consists of surface sheets and vertical support sheets. The longitudinal road side penetrating drainage body is small, easy in construction and high in drainage efficiency, is used to replace available longitudinal blind grooves on road sides and will not be damaged by the protective grating on road sides.
Description
1) Technical field [0001] The invention relates to the field of underground seepage removal, in particular to a core body for longitudinally draining water seepage at the edge of a pavement structure for removing seepage from pavement structures. 2) Background technology [0002] In highway engineering, in order to reduce water damage and eliminate water seepage in the pavement structure, it is necessary to set up a vertical drainage water body at the edge of the road surface. The water in the vertical drainage water body at the edge of the road surface is guided out of the road through horizontal outlet pipes arranged at a certain distance in the longitudinal direction. Currently, the known pavement edge The vertical drainage water body is composed of geotextile-wrapped drainage water body core. The commonly used vertical drainage water body core at the edge of the pavement in the prior art is crushed stone or buried permeable pipes in the crushed stone, or buried in cement ...
