Referring to fig. 1 to 3, the embodiment of the present invention provides an ecological water permeability garden path widening structure, which includes two widening structure bodies respectively located at two sides of the garden path 50, and the widening structure bodies include a water permeable filtering structure 10, a water storage device and a drainage device.

The permeable filtering structure 10 comprises a grass planting layer 11, a gravel layer 12, geotextile 13 and a stainless steel grating 14 which are sequentially arranged from top to bottom, wherein the grass planting layer 11 comprises a plurality of grass planting grids which are horizontally laid, and the stainless steel grating 14 is fixed at the top of a water storage channel 20. Surface water is collected in oozing the water storage channel 20 through the filtration of grass planting layer 11, metalling 12 and geotechnological cloth, realizes the primary filtration effect, and in addition, higher quality rainwater gets into the water storage channel 20 and has also reduced the bad consequence that earth deposit brought, reduces the oxygen cost of exposing to the sun. Further, the top surface of the permeable filtering structure 10 is lower than the top surface of the garden path 50, which is beneficial for the surface water on the garden path 50 to naturally flow into the permeable filtering structure, and a large amount of accumulated water is prevented from being formed on the garden path 50.

The water storage device includes a water storage channel 20 and a water pump, the water storage channel is located below the water permeable filtering structure 10, the water storage channel 20 is used for collecting surface water filtered by the water permeable filtering structure 10, in this embodiment, a bottom plate of the water storage channel 20 is a concrete member, and a side wall of the water storage channel 20 is a brick masonry. The water suction pump is communicated with the water storage channel 20 through the water suction pipe 30, at least one water suction through hole is formed in the water storage channel 20, at least one water suction branch pipe 31 is connected to the water suction pipe 30, the water suction branch pipe 31 penetrates through the water suction through hole and extends into the water storage channel 20, and the water suction pipe 30 and the water suction branch pipe 31 can be integrally formed. The outlet end of the suction pipe 30 is connected upward to a suction pump installed on the floor. The cover chamber 33 is arranged outside one side of the water storage channel 20 far away from the garden path 50, the water pumping pipe 30 is positioned in the cover chamber 33, and the cover chamber 33 protects the water pumping pipe 30. Preferably, a filtering device 32 is provided in the pumping pipe 30 to further improve the quality of the recovered water.

When rainstorm or continuous rainy days and the like occur, a large amount of surface water enters the water storage channel 20 through the permeable filtering structure, and excessive accumulated water in the water storage channel 20 is drained away through the drainage device. The drainage device comprises at least one overflow pipe 40 and a drainage pipe 41, the bottom plate of the water storage channel 20 is provided with at least one overflow through hole, the drainage pipe 41 is positioned below the water storage channel 20, the top end of the overflow pipe 40 penetrates through the overflow through hole and extends into the upper part of the water storage channel 20, and the bottom end of the overflow pipe 40 is communicated with the drainage pipe 41. An adhesive sealing layer is arranged between the outer side of the overflow pipe 40 and the overflow through hole, so that water in the water storage channel 20 is prevented from flowing away through a gap between the overflow pipe 40 and the overflow through hole. As the water storage capacity in the water storage channel 20 increases, the water level in the water storage channel 20 rises, and when the water level rises to the height of the top end of the overflow pipe 40, the accumulated water flows into the drain pipe 41 through the overflow pipe 40 and is drained away, so that the control of excess water flow is realized, and the erosion effect of rainwater on the ground surface is reduced. Further, the water inlet end of the water pumping branch pipe 31 is lower than the top end of the overflow pipe 40, so as to ensure that the water pumping branch pipe 31 can smoothly pump the stored water in the water storage channel 20.

The utility model discloses a construction method as follows to one of them side widens structure body and explains as an example:

s1, determining the width of the widened structure body according to calculation without processing the original pavement 50. The method comprises the following steps of downwards digging an edge soil subgrade on one side of a road surface to a certain depth, paving a drain pipe 41 on the dug surface, connecting and installing a plurality of overflow pipes 40 on the drain pipe 41, coating epoxy resin binder on the outside of the overflow pipes 40, and compacting the surrounding plain soil after the binder is firmly bonded.

S2, C25 concrete with the impervious grade of P6 is paved on the tamped plain soil to serve as a bottom plate of the water storage channel 20, sand-lime bricks are built around the bottom plate to serve as the side wall of the water storage channel 20, a water pumping through hole is reserved on the side wall far away from the garden road 50, and a cover chamber 33 is installed on the outer side of the side wall, provided with the water pumping through hole, of the water storage channel.
