The device is simple and practical.

In the prior art including the above patent, the existing blind ditches are easily affected by the uneven settlement of the ground during use, and when the uneven settlement occurs in the roadbed or foundation, the blind ditches are easily broken, resulting in difficulty in removing the groundwater.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel under concrete floor french drain drainage structure aims at solving traditional french drain and is easy when the ground is inhomogeneous to subside problem that fracture, groundwater are difficult to get rid of.

In order to realize above-mentioned purpose, the utility model provides a novel french drain drainage structure under concrete floor, including the body that is located concrete slab below, the body includes bottom and the side filter layer of symmetric distribution on the bottom, bottom and two the side filter layer is constituteed and is formed the rivers passageway, be provided with the triangular prism piece that is used for strengthening the bottom and is the linear array and distributes on the bottom.

Preferably, the bottom layer includes broken brick tamping layer and the concrete cushion that distributes in proper order, be provided with the triangular prism piece that is linear array and distributes on the concrete cushion.

Preferably, the side filter layer comprises a gravel reverse filter layer, a pebble reverse filter layer and a water seepage wall which are distributed in sequence, and the gravel reverse filter layer is attached to the triangular prism blocks.

Preferably, the triangular prism block is internally provided with a reinforcing rib.

In the technical scheme, the utility model provides a pair of novel under concrete floor french drain drainage structure possesses following beneficial effect: the bottom of body has been strengthened greatly to triangular prism piece, makes the wholeness of bottom improve greatly, makes the contact between body and the ground weaken, and the body has certain ability of resisting the uneven settlement in ground, and triangular prism piece separates the rivers passageway, falls into a plurality of water courses with the bottom of rivers passageway, can gather the water in the rivers passageway fast and become the stream, can make water flow away fast.

1. a body; 11. a broken brick tamping layer; 12. a concrete cushion; 13. a water seepage wall; 14. a pebble inverted filter layer; 15. a sandstone inverted filter layer; 16. a triangular prism block; 17. reinforcing ribs; 2. a concrete slab.

Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, a novel drainage structure for a blind drain under a concrete floor comprises a body 1 positioned below a concrete slab 2, wherein the body 1 comprises a bottom layer and side filter layers symmetrically distributed on the bottom layer, the bottom layer and the two side filter layers are combined to form a water flow channel, and triangular prism blocks 16 which are used for reinforcing the bottom layer and distributed in a linear array are arranged on the bottom layer.

Specifically, the body 1 in the above embodiment is specifically a blind ditch.

Among the above-mentioned technical scheme, the bottom of body 1 has been strengthened greatly to triangular prism piece 16, makes the wholeness of bottom improve greatly, makes the contact between body 1 and the ground weaken, and body 1 has certain ability of resisting ground differential settlement, and triangular prism piece 16 separates the flowing water passageway, falls into a plurality of water courses with the bottom of flowing water passageway, can gather the stream with the water in the flowing water passageway fast, can make water flow away fast.

As a further embodiment of the present invention, as shown in fig. 1-2, the bottom layer includes a crushed brick tamping layer 11 and a concrete cushion layer 12 which are distributed in sequence, and triangular prism blocks 16 distributed in a linear array are arranged on the concrete cushion layer 12; the broken brick tamping layer 11 makes a good foundation for the concrete cushion 12, reduces the influence of ground subsidence on the concrete cushion 12, and the concrete cushion 12 forms the bottom surface of flowing water passageway, avoids groundwater to continue subsiding.

As a further embodiment provided by the present invention, as shown in fig. 2, the side filter layer includes a gravel reverse filter layer 15, a pebble reverse filter layer 14 and a permeable wall 13 which are distributed in sequence, and the gravel reverse filter layer 15 is attached to the triangular prism block 16, and the permeable wall 13, the pebble reverse filter layer 14 and the pebble reverse filter layer 15 perform multi-layer filtration on the groundwater, so as to slow down soil and water loss.

As a further embodiment provided by the present application, as shown in fig. 2, a reinforcing rib 17 is provided inside the triangular prism block 16, and the reinforcing rib 17 can enhance the toughness of the triangular prism block 16 so as to reinforce the concrete cushion 12.
