Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a concrete prefab permeates water, including road block one 1 and road block two 2. The first road block 1 and the second road block 2 are rectangular plate-shaped, one side of the edge of the first road block 1 and one side of the edge of the second road block 2 are connected through a long-strip-shaped coarse aggregate permeable concrete layer 10 to form a single-vehicle roadway, and two parallel permeable concrete prefabricated parts form a double-vehicle roadway. The aggregate of the coarse aggregate pervious concrete layer is 2cm to 5cm in diameter, and the aggregate of the exposed aggregate pervious concrete layer is less than 1cm in diameter.

Referring to fig. 2, two ends of the first road block 1 and the second road block 2 in the horizontal direction, which are perpendicular to the connecting direction of the first road block 1 and the second road block 2, are respectively provided with a protrusion 8, the two protrusions 8 and end faces of the two ends respectively form a downward or upward concave 9, and the protrusion 8 at one end of the concrete prefabricated member and the concave 9 at the other end of the concrete prefabricated member are matched with each other, so that the adjacent permeable concrete prefabricated members are mutually abutted.

Referring to fig. 3 and 4, the first road block 1 and the second road block 2 comprise an exposed aggregate permeable concrete layer 3, a gravel layer 4 and a reinforcing steel layer 5, and the first road block 1 and the second road block 2 are respectively the exposed aggregate permeable concrete layer 3, the reinforcing steel layer 5, the gravel layer 4, the reinforcing steel layer 5 and the exposed aggregate permeable concrete layer 3 from top to bottom.

The exposed aggregate permeable concrete layer 3 on the surfaces above the first road block 1 and the second road block 2 is respectively provided with two grooves 6, the bottoms of the grooves 6 are provided with upward pull rings 7, and the pull rings 7 are arranged to move the concrete prefabricated member freely through a crane, so that labor is saved.

Referring to fig. 4 and 5, the two reinforcing steel layers 5 are respectively formed into a grid shape by a plurality of reinforcing steel bars, two ends of the two reinforcing steel layers 5 are fixed by a plurality of vertical reinforcing steel bars, the gravel layer 4 is filled between the two reinforcing steel layers 5, and the exposed aggregate permeable concrete layer 3 is wrapped outside the reinforcing steel layers 5.

The round pipe-shaped concrete pipe 12 is arranged in the gravel layer 4, and the round pipe-shaped concrete pipe 12 is added in the gravel layer 4, so that the quality of the concrete prefabricated member can be reduced, and the energy can be saved in long-distance transportation.

Referring to fig. 6, the upper surface between the first road block 1 and the second road block 2 is respectively inclined from the side far away from the coarse aggregate permeable concrete layer 10 to the direction of the coarse aggregate permeable concrete layer 10 from high to low. The purpose of this is that water on the road surface can flow to the coarse aggregate pervious concrete layer 10 to rapidly infiltrate into the ground.

The bottom of the coarse aggregate pervious concrete layer 10 is provided with an arch-shaped water storage cavity 11 which is sunken upwards, so that the problem that accumulated water on the surface of a road is accumulated on a road surface for a long time due to slow water seepage of a bottom soil layer is avoided.

The implementation principle of the embodiment is as follows:

when raining, one part of rainwater permeates the exposed aggregate permeable concrete layer 3 and the gravel layer 4 and permeates underground, the other part of rainwater cannot directly and vertically permeate underground, the rainwater firstly passes through the inclined planes on the upper surfaces of the first road block 1 and the second road block 2 and is drained to the surface of the coarse aggregate permeable concrete layer 10 in the middle, and the coarse aggregate permeable concrete layer 10 can quickly drain accumulated water on the surface of the road to underground compared with the exposed aggregate permeable concrete layer 3.

Meanwhile, the strength of the coarse aggregate pervious concrete layer 10 is lower than that of the exposed aggregate pervious concrete layer 3, and the coarse aggregate pervious concrete layer 10 is arranged in the middle of the roadway, so that the wheel pressure probability of the vehicle is reduced.

When excessive ponding produces on the road, ponding is drained to way middle part, the vehicle bottom promptly, and ponding does not contact with the wheel, reduces rainy day road accident and takes place, and secondly, the roadside pedestrian also is difficult to be spattered by ponding.

In the installation process, after the pull rings 7 of the grooves 6 on the upper surfaces of the first road block 1 and the second road block 2 are hung and placed, the grooves 6 are leveled by casting concrete, then the concave parts 9 of the adjacent permeable concrete prefabricated parts are abutted with the convex parts 8 of the adjacent permeable concrete prefabricated parts, and gaps between the adjacent permeable concrete prefabricated parts are cast.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
