Further, the water storage tank is provided with a transverse water pipeline, the elevation of the transverse water pipeline is higher than that of the transverse drainage pipeline, and the transverse water pipeline is connected with an external drainage facility.
The beneficial effects are that: in this ecological square road roadbed structure in sponge city, constitute three-dimensional drainage system through basic unit and the vertical drainage water collecting well that permeates water, the ponding of oozing down flows to each vertical drainage water collecting well through basic unit that permeates water, and ponding rethread horizontal drainage pipe in each vertical drainage water collecting well outwards discharges, reaches the mesh with ponding rapid drainage, avoids ponding accumulation.
Drawings
The invention is further described below with reference to the drawings and examples;
fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
Referring to fig. 1, the road subgrade structure of the sponge city ecological square comprises a road surface layer 10 and a road base layer 20, wherein the road surface layer 10 is formed by paving permeable bricks, the road base layer 20 comprises a permeable base layer 21 and a impermeable base layer 22 which are vertically spaced, a plurality of vertical drainage water collecting wells 23 are arranged between the permeable base layer 21 and the impermeable base layer 22 at intervals and are backfilled to form a road foundation soil layer 24, the permeable base layer 21 is formed by casting permeable concrete, the impermeable base layer 22 is formed by casting impermeable concrete, the vertical drainage water collecting wells 23 are formed by filling crushed gravel, rainwater ponding permeates the road surface layer 10 to the permeable base layer 21, water accumulated in the permeable base layer 21 can continuously permeate downwards or horizontally permeate, the permeated water is collected and gathered through the vertical drainage water collecting wells 23, the vertical drainage water collecting wells 23 are distributed in a step-shaped arrangement from the middle to the two sides, namely, the heights of the bottoms of the vertical drainage water collecting wells 23 are sequentially decreased from the middle to the two sides, the adjacent vertical drainage water collecting wells 23 are connected through transverse water accumulating channels 25, the vertical drainage water collecting wells 23 at the two sides are connected with external drainage facilities through the transverse water accumulating channels 25, and the water accumulated outside the drainage facilities are rapidly drained outside through the drainage channels 25, and the drainage facilities can drain water rapidly and drain water outside the drainage facilities.
The vertical drainage water collection well 23 is of a step-type design, so that accumulated water in the middle can be effectively drained to two sides rapidly, and accumulated water accumulation is avoided.
The vertical drainage water collection well 23 is preferably filled with crushed gravel, and the crushed gravel can have a precipitation filtering effect on accumulated water and avoid blocking the transverse drainage pipeline 25.
Preferably, the impermeable geomembrane material is laid on the top surface of the impermeable base layer 22, so that the internal accumulated water can be prevented from continuously flowing downwards, and is forced to flow to the nearby vertical drainage water collecting well 23, and the drainage effect is enhanced.
