Detailed Description

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

In this embodiment: referring to fig. 1, for the utility model discloses a sponge type road pavement structure for municipal garden, including two relative fender walls 1 that set up, fender wall 1 specifically adopts concrete placement to form. Two keep off and are equipped with brick layer 2 that permeates water between the wall 1, the lower surface of brick layer 2 that permeates water is equipped with well sand bed 4, and the lower surface of well sand bed 4 is equipped with coarse sand layer 5, and coarse sand layer 5's lower surface is equipped with the geotechnological cloth that permeates water, and the lower surface of geotechnological cloth that permeates water is equipped with rubble bed course 7, and the lower surface of rubble bed course 7 is equipped with the baffle 8 that permeates water, and the below of baffle 8 that permeates. Wherein the bottom of the retaining wall 1 extends to the bottom of the reservoir 9. During raining, the rainwater falling on the surface of the water permeable brick 21 can sequentially penetrate through the water permeable brick layer 2, the grating layer 3, the medium sand layer 4, the coarse sand layer 5, the water permeable geotextile, the gravel cushion layer 7 and the water permeable baffle 8, and finally, the rainwater filtered by each layer enters the reservoir 9, so that the problem of rainwater accumulation on the surface area of the road is favorably reduced.

Referring to fig. 1, drainage ditches 10 are disposed at two sides of the water storage tank 9, a first water outlet 11 for communicating the drainage ditches 10 with the water storage tank 9 is disposed on the water storage tank 9, and the position of the first water outlet 11 is higher than the bottom of the drainage ditches 10, so that rainwater in the drainage ditches 10 can be prevented from flowing back to the water storage tank 9. In addition, a first check valve 111 is disposed at the first water outlet 11, the first check valve 111 is specifically a one-way electric control valve, and the first check valve 111 is electrically connected to a switch for controlling the first check valve 111 to open and close. When raining, the first check valve 111 can be opened by opening the switch for controlling the first check valve 111, so that rainwater in the reservoir 9 can enter the drainage ditch 10 from the reservoir 9, and the phenomenon of full load of the reservoir 9 is avoided.

Referring to fig. 2 and 3, in order to further improve the drainage performance of the road, in the present embodiment, a grid layer 3 is provided between the water permeable brick layer 2 (see fig. 1) and the medium sand layer 4 (see fig. 1). Wherein, grid layer 3 includes two horizontal and parallel arrangement's grid 31 from top to bottom, and each grid 31 all includes vertically and horizontally staggered's horizontal bar 311 and vertical bar 312, and is connected with the support bar 32 perpendicularly between two parallel arrangement's the grid 31, and the support bar 32 is located the crossing department of horizontal bar 311 and vertical bar 312 to grid layer 3 and two keep off and form a cavity 33 that has the water storage effect between wall 1. When the water penetration speed of the middle sand layer 4, the coarse sand layer 5 and the like is slow, the cavity 33 can temporarily receive rainwater penetrating through the water permeable brick layer 2, so that the possibility of rainwater accumulation on the surface of a road is reduced, and the drainage performance of the road is improved.

In addition, in order to prevent the problem that rainwater stored in the cavity 33 cannot permeate into the reservoir 9 in time when raining, in this embodiment, referring to fig. 1, the blocking wall 1 is respectively provided with a second water outlet 12 at one side of the grid layer 3 close to the drainage ditch 10, a second one-way valve 121 is arranged at the second water outlet 12, the second one-way valve 121 is also a one-way electrically controlled valve, and the second one-way valve 121 is electrically connected with a switch for controlling the second one-way valve 121 to open and close. When rain is heavy, the second one-way valve 121 can be opened by opening the switch for controlling the second one-way valve 121, so that rainwater in the cavity 33 can enter the drainage ditch 10 through the second water outlet 12, and rainwater in the water permeable brick layer 2 cannot be influenced to continuously permeate into the grating layer 3.

Because the rainwater is generally acidic, the grid layer 3 can be made of corrosion-resistant concrete materials and can also be made of acid-resistant stainless steel materials, so that the grid layer is corrosion-resistant and is favorable for providing a good supporting effect for the permeable brick layer 2.

Referring to fig. 1 and 4, in order to further improve the water permeability of the road, in this embodiment, the water permeable brick layer 2 is formed by sequentially laying a plurality of water permeable bricks 21. Wherein, the brick 21 that permeates water includes the brick body 211 that permeates water, and the bottom of the brick body 211 that permeates water has the loading board 212 along the length direction or the width direction level outside extension of the brick body 211 that permeates water, is equipped with the hole 213 of permeating water on the loading board 212. When splicing two adjacent water permeable brick bodies 211 together, a larger gap exists between the two adjacent water permeable brick bodies 211, and the effect of facilitating rainwater to penetrate through the gap and enter the grid layer 3 is achieved.

In order to prevent the impurities with a large volume from entering the grid layer 3, the bearing plate 212 is filled with a cobble layer 22 composed of cobbles. The volume of the cobblestones in the cobblestone layer 22 is larger than the diameter of the water permeable holes 213, so that the problem that the cobblestones enter the cavity 33 through the water permeable holes 213 can be prevented. In addition, the upper surface of the cobble layer 22 is flush with the upper surface of the water permeable brick body 211, so that the problem that a pedestrian falls down due to stepping on the water permeable brick body can be prevented.

The implementation principle of the embodiment is as follows: when raining, rainwater permeates into the grid layer 3 through the permeable brick layer 2 and the cobble layer 22, and a part of the rainwater in the grid layer 3 can sequentially permeate through the medium sand layer 4, the coarse sand layer 5, the permeable geotextile, the gravel cushion 7 and the permeable baffle 8, finally enter the reservoir 9 and are discharged through the first water outlet 11; in addition, rainwater in the grid layer 3 can be drained to the drainage ditch 10 from the second water outlet 12 on one side of the grid layer 3, so that quick drainage is facilitated, and the problem that rainwater is easy to remain on the road surface and affects the walking of pedestrians is solved.

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.
