Disclosure of Invention

To exist not enough among the prior art, the utility model provides a barricade and side ditch assembly with drainage function occupies the soil less, can practice thrift the land and collect fee, and drainage effect is good. The utility model adopts the technical proposal that:

the utility model provides a barricade and side ditch assembly with drainage function, includes: retaining walls, side ditches and seepage water collecting structures;

a retaining wall is arranged on the outer side of the side ditch; the side foundation and the bottom foundation of the side ditch are integrally constructed with the retaining wall;

the top of the side ditch is covered with a cover plate; the cover plates are continuously arranged along the side ditch; each cover plate is provided with a rainwater hole;

the outer side of the retaining wall is provided with a water seepage collecting structure which discharges collected seepage to the side ditch through transverse drainage pipes arranged in the retaining wall at intervals.

Further, the seepage water collecting structure comprises geotextile, a blind pipe and graded broken stones; the blind pipes are distributed on the outer side close to the retaining wall along the length direction of the retaining wall; graded broken stones are covered outside the blind pipe; geotextile is arranged outside the graded broken stone; the blind pipes are connected with a transverse drain pipe at intervals.

Further, the lateral drain pipe is disposed to be inclined downward from the outside to the inside.

Furthermore, reinforcing steel bars are arranged in the ditch side foundation, the ditch bottom foundation and the retaining wall of the side ditch; the arrangement direction of the reinforcing steel bars is along the length direction of the retaining wall.

Furthermore, one transverse drain pipe is arranged at intervals of 10-20 m.

Compared with the prior art, the utility model has the advantages of:

1) the retaining wall is used as the outer side wall of the side ditch, so that the land occupation can be reduced.

2) Pedestrians or non-motor vehicles can pass through the cover plate, and the occupied area of the road can be saved.

3) The accumulated water behind the retaining wall can be collected through the water seepage collecting structure and then discharged through the transverse water discharging pipe.

4) The retaining wall and the side ditch base body are connected into a whole, and gap water seepage between the retaining wall and the side ditch base body is prevented.

Drawings

Fig. 1 is a general schematic diagram of the structure in the embodiment of the present invention.

Fig. 2 is the embodiment of the present invention provides a schematic diagram of a seepage water collecting structure.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1, the utility model provides a barricade and side ditch assembly with drainage function, include: the device comprises a retaining wall 1, a side ditch 2 and a seepage water collecting structure 3;

a retaining wall 1 is arranged on the outer side of the side ditch 2; in this embodiment, the side of the hill or mound is defined as the outer side;

the trench side foundation 22 and the trench bottom foundation 23 of the side trench 2 are integrally constructed with the retaining wall 1; in other words, the trench-side foundations 22 and the trench-bottom foundations 23 are cast together with the retaining wall 1 at the time of casting;

reinforcing steel bars 11 are arranged in the ditch side foundation 22, the ditch bottom foundation 23 and the retaining wall 1 of the side ditch 2; the arrangement direction of the steel bars 11 is along the length direction of the retaining wall 1;

the top of the side ditch 2 is covered with a cover plate 21; the cover plates 21 are continuously arranged along the side ditch 2; each cover plate 21 is provided with a rainwater hole; the side ditches 2 are covered by the cover plates 21 which are continuously arranged, so that the upper part of the cover plates 21 also has traffic capacity, and land occupied by roads is saved;

the outer side of the retaining wall 1 (namely a mountain or in mound) is provided with a seepage water collecting structure 3, and the seepage water collecting structure 3 drains collected seepage water to the side ditch 2 through transverse drain pipes 4 which are arranged in the retaining wall 1 at intervals; in the embodiment shown in fig. 1, one transverse drain pipe 4 is arranged at intervals of 10-20 m, and the transverse drain pipe 4 is arranged in a downward inclination from the outer side to the inner side so as to facilitate the drainage of seepage water;

in the example shown in fig. 2, the water-permeable collection structure 3 comprises a geotextile 31, a blind pipe 32, graded crushed stones 33; the blind pipes 32 are arranged at the outer side close to the retaining wall 1 along the length direction of the retaining wall 1; the blind pipe 32 is externally coated with graded broken stones 33; geotextile 31 is arranged outside the graded broken stones 33; the blind pipes 32 are connected with a transverse drain pipe 4 at intervals;
