The utility model aims at overcoming the defects in the prior art and providing a semicircular drainage channel.

The semicircular drainage channel comprises a reverse filter geotextile, a hole group, a special PVC pipe, a notch, a reinforcing rib, a bottom plate, a convex opening, a longitudinal rib and a transverse rib; the bottom plate is a reinforced concrete bottom plate, longitudinal ribs and transverse ribs are arranged in the bottom plate, and convex openings and concave openings are formed in the two ends of the bottom plate respectively; the reinforcing ribs are stainless steel semicircular arch structures and are connected with the reinforcing steel bars of the bottom plate; the special PVC pipe is of a semicircular structure, the special PVC pipe is arranged on the bottom plate and the reinforcing ribs, and the pipe wall of the special PVC pipe is provided with a hole group and covered with the reverse filter geotextile.

Preferably, the method comprises the following steps: the reinforcing ribs are connected at the intersections of the longitudinal ribs and the transverse ribs in the reinforcing mesh of the base plate.

Preferably, the method comprises the following steps: the bottom plate is reserved with an embedded pipe groove of a special PVC pipe.

Preferably, the method comprises the following steps: the semicircular drainage channel unit bodies are connected through the convex openings and the concave openings.

The utility model has the advantages that: the utility model discloses a semicircle form drainage channel simple structure, construction convenience, than circular tubulose drainage channel, the volume of digging the side significantly reduces, and can guarantee the drainage requirement.

Detailed Description

The present invention will be further described with reference to the following examples. The following description of the embodiments is merely provided to aid in understanding the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.

The semicircular drainage channel comprises a reverse filtering geotextile 4, a hole group 8, a special PVC pipe 9, a notch 10, a reinforcing rib 11, a bottom plate 12, a convex opening 13, a longitudinal rib 14 and a transverse rib 15; the bottom plate 12 is a reinforced concrete bottom plate, longitudinal ribs 14 and transverse ribs 15 are arranged in the bottom plate 12, and two ends of the bottom plate 12 are respectively provided with a convex opening 13 and a concave opening 10; the reinforcing ribs 11 are stainless steel semicircular arch structures, and the reinforcing ribs 11 are connected with the reinforcing steel bars of the bottom plate 12; the special PVC pipe 9 is of a semicircular structure, the special PVC pipe 9 is arranged on the bottom plate 12 and the reinforcing ribs 11, and the pipe wall of the special PVC pipe 9 is provided with the hole group 8 and covered with the reverse filter geotextile 4.

The reinforcing bars 11 are connected at the intersections of the longitudinal bars 14 and the transverse bars 15 in the mesh reinforcement of the base plate 12.

The bottom plate 12 is reserved with a mosaic pipe groove of a special PVC pipe 9.

The semicircular drainage channel unit bodies are connected with the notch 10 through the convex opening 13.

The semicircular drainage channel and the vegetation cover layer 1, the planting soil layer 2, the sand layer 3, the reverse filter geotextile 4, the gravel cushion layer 5 and the plain soil base layer 7 which are sequentially arranged from top to bottom form a green belt drainage system.

The construction method of the semicircular drainage channel comprises the following steps:

firstly, as shown in figure 3, prefabricating semicircular drainage channel unit bodies, reinforcing bars for a bottom plate 12, connecting reinforcing ribs 11 at the intersection of longitudinal ribs 14 and transverse ribs 15 in a reinforcing mesh, configuring C25 concrete for pouring the bottom plate 12, reserving an embedded pipe groove of a special PVC pipe 9 and a notch 10 and a convex opening 13 for connecting the semicircular drainage channel unit bodies, as shown in figure 2, opening a hole group 8 on the pipe wall of the special PVC pipe 9, after the pouring and maintenance of the bottom plate 12 are completed, installing the special PVC pipe 9 in the pipe groove on the bottom plate 12, and covering the outer wall with the anti-filtration geotextile 4.

And step two, digging a ditch, tamping a plain soil base layer 7 when a semicircular drainage channel is buried, making a waterproof measure when a notch 10 and a convex opening 13 of the channel are connected, backfilling a gravel cushion layer 5 around the drainage channel after laying, laying a layer of reverse filtering geotextile 4 about 15-20cm higher than the top of the channel, backfilling a sand layer 3 with the thickness of 10-15cm, and finally backfilling a planting soil layer 2 with the thickness of 30-40cm, so that various green landscape plants can be planted on the vegetation cover layer 1, as shown in figure 1.
