A plurality of catch basins are arranged at intervals on one side of the concrete road surface. A plurality of grooves corresponding to the plurality of catch basins one by one are arranged at intervals along the length direction of the concrete road surface. The grooves are all strip-shaped and are arranged along the width direction of the concrete road surface. One end of the groove is communicated with the corresponding catch basin. A water-permeable surface layer and a permeable layer are laid in the groove from top to bottom.

[0007] Preferably, in the blind ditch structure using the transformation of a concrete road surface, a drain pipe is buried along the length of the corresponding groove in the permeable layer. The drain pipe is hollow inside, and one end thereof close to the corresponding catch basin is open, and the open end horizontally extends into the corresponding catch basin. A plurality of water inlets are arranged at intervals on the upper part of the drain pipe.

[0008] Preferably, in the blind ditch structure using the transformation of a concrete road surface, the bottom wall of the drain pipe is an inclined surface, and the inclined surface is inclined towards the open end of the drain pipe.

[0009] Preferably, in the blind ditch structure using the concrete pavement reconstruction, covers for opening or closing both ends of the drain pipe are provided. An extension part is provided at one end of the cover away from the inner wall of the drain pipe. A plurality of elastic members are spaced between the extension part and the inner wall of the drain pipe. Under the action of gravity and the corresponding elastic members, one end of the cover close to the inner wall of the drain pipe closes the corresponding water inlet.

[0010] The present invention also provides a construction method for the blind ditch structure using the concrete pavement reconstruction, including the following steps:

[0022] The following further describes the present invention in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0023] It should be noted that in the description of the present invention, the orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] As shown in Figure 1 - Figure 2 An embodiment of the present invention provides a blind ditch structure using a concrete road surface reconstruction. A plurality of catch basins are arranged at intervals on one side of the concrete road surface 1. A plurality of grooves 2 corresponding to the plurality of catch basins are arranged at intervals along the length direction of the concrete road surface 1. The grooves 2 are all strip-shaped and are arranged along the width direction of the concrete road surface 1. One end of the groove 2 is communicated with the corresponding catch basin. A permeable surface layer 3 and a permeable layer 4 are laid in the groove 2 from top to bottom. The permeable surface layer 3 is made of permeable asphalt or permeable concrete; the permeable layer 4 is composed of a plurality of pebbles with a particle size of 3-5 cm.

[0025] In this embodiment, grooves can be opened on both sides of the concrete road surface 1 along its width direction. The grooves 2 are all filled with pebbles with a particle size of 3-5 cm. The arrangement direction of the grooves 2 is fully combined with the positions of the catch basins or rainwater and sewage wells on both sides of the road. Then a layer of permeable asphalt or permeable concrete is paved on the entire surface layer. This method avoids large-area breaking of the concrete road surface 1, reduces the installation of a large number of drainage pipes, etc., reduces the transportation of slag blocks, and reduces costs. At the same time, a criss-cross drainage blind ditch is formed under the road, and the blind ditch is connected to the catch basin and the rainwater and sewage wells. The rainwater infiltrated in the permeable road surface can quickly enter the drainage pipe 5 through the blind ditch, achieving the drainage concept of a sponge city.

[0026] Preferably, as another embodiment of the present invention, as shown in Figure 2 andFigure 3 As shown, a drain pipe 5 is buried along the length of the corresponding groove 2 in the permeable layer 4. The drain pipe 5 is hollow inside, with one end close to the corresponding catch basin open, and its open end extends horizontally into the corresponding catch basin. A plurality of water inlets 6 are arranged at intervals on the upper part of the drain pipe 5. The bottom wall of the drain pipe 5 is an inclined surface, and the inclined surface is inclined towards the open end of the drain pipe 5. Covers 7 that can open or close the drain pipe 5 are provided at both open ends of the drain pipe 5. An extension part is provided at one end of the cover 7 away from the inner wall of the drain pipe 5. A plurality of elastic members 8 are arranged at intervals between the extension part and the inner wall of the drain pipe 5. Under the action of gravity and the corresponding elastic members 8, one end of the cover 7 close to the inner wall of the drain pipe 5 closes the corresponding water inlet 6.

[0027] In this embodiment, the drain pipe 5 is arranged in the permeable layer 4, and a plurality of water inlets 6 are arranged at intervals at the upper end of the drain pipe 5, which can accelerate the drainage speed of the permeable layer 4. At the same time, in order to prevent sundries from blocking the drain outlet when not in use, a cover 7 that automatically opens the corresponding water inlet 6 when water drains into the pipe in the permeable layer 4 is arranged below each drain outlet, and the cover 7 closes the corresponding water inlet 6 when there is no water draining into the pipe in the permeable layer 4. In this embodiment, the elastic member 8 can be made of a spring. When the cover 7 closes or opens the corresponding water inlet 6, the elastic member 8 is stretched by the cover 7, and the elastic member 8 exerts an upward force on the cover 7, so that the cover 7 is stationary under the combined action of gravity and the force of the elastic member 8 on it. When water drains into the pipe in the permeable layer 4, the gravity of the water flow and the impact force on the cover 7 cause the cover 7 to move downward, thus opening the drain outlet. After the drainage in the permeable layer 4 stops, the cover 7 moves upward under the action of the elastic member 8 to seal the drain outlet.

[0028] The present invention also provides a construction method for a blind ditch structure using a concrete pavement transformation, including the following steps:

[0029] S1. Select a concrete pavement 1 with a plurality of catch basins arranged at intervals on one side;

[0030] S2. A plurality of grooves 2 corresponding to the plurality of catch basins one by one are arranged at intervals along the length direction of the concrete pavement 1. The grooves 2 are arranged along the width direction of the concrete pavement 1, and one end of the groove 2 is communicated with the corresponding catch basin;

[0031] S3. Lay a permeable layer 4 in the groove 2, and then lay a permeable surface layer 3 above the permeable layer 4. The upper end surface of the permeable surface layer 3 is flush with the concrete pavement 1. The permeable surface layer 3 is made of permeable asphalt or permeable concrete. The permeable layer 4 is composed of a plurality of pebbles with a particle size of 3 - 5 cm;

[0032] Among them, in the step S3, when laying the permeable layer 4 in the trench 2, a drain pipe 5 is buried along the length of the trench 2 in the permeable layer 4. The drain pipe 5 is hollow inside, and one end thereof close to the corresponding catch basin is open, and the open end thereof extends horizontally into the corresponding catch basin. A plurality of water inlets 6 are arranged at intervals on the upper part of the drain pipe 5.

[0033] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the embodiments shown and described herein.
