Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a sponge city green channel seepage and drainage system. Referring to fig. 1 and 2, the sponge city green channel seepage and drainage system comprises drainage ditches 1 arranged at two sides of a green channel and an irrigation mechanism communicated with the bottoms of the drainage ditches 1.

Referring to fig. 2 and 4, the irrigation mechanism comprises a plurality of drainage pipes 21 communicated with the lower part of the side wall of the drainage ditch 1, a water distribution pipe 22 communicated with one end of the drainage pipe 21 far away from the drainage ditch 1, and a plurality of water seepage pipes 23 communicated with the water distribution pipe 22, wherein the water seepage pipes 23 are positioned in a soil layer below the green belt and have a horizontal height not higher than the bottom of the drainage ditch 1. One side of the drainage pipe 21 close to the drainage ditch 1 is provided with a drainage valve 211, and the water seepage pipe 23 is provided with a plurality of water seepage holes 231.

When raining, rainwater on the green road surface flows into the drainage ditch 1, the drainage ditch 1 collects rainwater, when the green belt is watered as required, the drainage valve 211 is opened, rainwater collected in the drainage ditch 1 flows into the water seepage pipe 23 through the drainage pipe 21, and then permeates into the soil layer below the green belt through the water seepage hole 231, so that the soil layer of the green belt is watered. When the greenbelt does not need watering, close drain valve 211, the rainwater of collecting is stored in escape canal 1, avoids the rainwater to ooze through infiltration hole 231 all the time and causes the waste of rainwater.

In this embodiment, escape canal 1 is concrete placement, and drain pipe 21, water distributor 22 and infiltration pipe 23 all are the PVC pipe, and concrete placement is easy to be under construction, and durable, PVC manages corrosion-resistant, makes irrigation mechanism have longer life.

Referring to fig. 4, in order to prevent soil in the soil layer of the green belt from entering the water seepage holes 231 and blocking the water seepage holes 231, the outer wall of the water seepage pipe 23 is covered with geotextile 7. The geotextile 7 can ensure that the rainwater in the water seepage pipe 23 can seep out to the soil layer, and can prevent the rainwater from seeping out due to the influence of the soil blocking the water seepage hole 231.

In order to prevent that infiltration pipe 23 infiltration ability is not enough when the rainfall is too big and leads to the rainwater to spill over the road surface from escape canal 1, there is overflow pipe 3 in the upper portion intercommunication of 1 lateral wall in escape canal, and overflow pipe 3 keeps away from the one end intercommunication in urban drainage system in escape canal 1. When 1 interior water level of escape canal rises to when 3 level with the overflow pipe mutually, the rainwater can flow into urban drainage system through overflow pipe 3, avoids the rainwater to spill over and lead to green road surface ponding from 1 interior escape canal.

Referring to fig. 2 and 3, the support beams 11 are horizontally and symmetrically arranged on both sides of the inner wall of the drainage ditch 1, and in this embodiment, the support beams 11 and the drainage ditch 1 are formed by integrally pouring concrete. The support beam 11 is detachably provided with the grating 4, and the lower surface of the grating 4 is abutted against the upper surface of the support beam 11. Grid 4 can prevent that the foreign matter from getting into escape canal 1, avoids debris to block up drain pipe 21 and overflow pipe 3, also can shelter from escape canal 1, prevents that the pedestrian accident from stepping on empty and falling into escape canal 1 and taking place danger, and grid 4's detachable simple to operate regularly pulls down grid 4 and clears up escape canal 1.

Referring to fig. 1 and 2, the horizontal height of the grid 4 is lower than the green road surface, a plurality of plant growth bags 5 are placed above the grid 4, and the plant growth bags 5 are paved above the grid 4. Plant and give birth to bag 5 and can increase the afforestation area to plant and give birth to bag 5 and be located 4 tops of grid and make and flow through earlier when rainwater flows into escape canal 1 and give birth to bag 5, and then play the filter effect to the rainwater, avoid the foreign matter to flow into escape canal 1 along with the rainwater through the gap department of grid 4.

Referring to fig. 3, filter cloth 6 is laid between the vegetation bags 5 and the grid 4 so as to filter the silt in the rainwater, avoid excessive silt from entering the drainage ditch 1 and bringing inconvenience to the cleaning of the drainage ditch 1, and also prevent silt from entering the strainer and blocking the strainer holes.

Referring to fig. 2, in order to reduce the possibility of foreign matter entering the drain pipe 21, a filter mesh 8 is installed at the junction between the drain pipe 21 and the inside of the drain 1. Filter screen 8 can further filter the rainwater that gets into escape canal 1 to there is certain buffer space between the mouth of pipe of filter screen 8 and drain pipe 21, can avoid the foreign matter to hide the mouth of pipe of drain pipe 21 and lead to the transport of rainwater to be obstructed.

The implementation principle of the sponge city green channel seepage and drainage system is as follows: collect the rainwater through the escape canal 1 of green way both sides, the rainwater of collecting can flow into infiltration pipe 23 through drain pipe 21 in, then water in the soil layer of infiltration greenbelt below through infiltration hole 231, through carrying out recycle and with the watering that is used for the greenbelt to the rainwater, reduced the water demand of city water to the burden of city water has been alleviateed.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
