In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and fig. 2, a garden drainage ditch according to the present invention will now be described. The garden drainage ditch comprises a ditch frame 1, a filtering piece 2 and a purifying piece 3.

The ditch frame 1 is provided with a water through cavity 11, the top surface of the ditch frame 1 is provided with a water through hole 12 connected with the water through cavity 11, and the bottom surface is provided with a water drain hole 13 connected with the water through cavity 11; wherein, the aperture of the water through hole 12 is larger than the solid impurities in the surface water, and the water discharging hole 13 is connected with the soil base 300. When surface water flows from the road 100 to the green area 200, the surface water flows into the water passing chamber 11 along the water passing hole 12 and is discharged to the ground through the water discharging hole 13.

The filtering piece 2 is arranged in the water passing cavity 11 and divides the water passing cavity 11 into an upper first cavity channel and a lower second cavity channel; the filtering piece 2 is used for removing solid impurities in surface water, and the filtering principle is as follows: the smallest particles that can be trapped by the filter element 2 are smaller in size than the aforesaid solid impurities, so that the solid impurities inside the filter element 2 are separated and accumulated in the first channel when the surface water passes through the filter element 2. And when cleaning the solid impurities in the water through cavity 11 after rain, the rain water in the water through cavity 11 is discharged into the soil base 300 along the water discharge hole 13, so the solid impurities can fall on the top surface of the filter element 2, and the filter element 2 is removed and taken out, thereby the cleaning of the solid impurities can be realized, and the implementation is very convenient. Be equipped with supplementary infiltration hole 111 on the lateral wall of second chamber way, this supplementary infiltration hole 111 is used for linking to each other with the underground portion of road and afforestation area 200, has improved the drainage efficiency of second chamber way, avoids the second chamber to be filled up and can't make surface water pass through and filter piece 2 for filter piece 2 of this device can't take effect.

With purifying member 3 and setting up in the second chamber way, can avoid purifying member 3 and aforementioned solid impurity to take place the reaction, improved the effective use rate of purifying member 3.

When raining (or snowing, hail and other natural weather which can form liquid), rainwater falls on the road 100 to gradually form surface water and flows to the greening area 200, and the water through holes 12 on the top surface of the ditch frame 1 can play the roles of intercepting and dissipating energy for the surface water, so that the surface water is introduced into the water through cavity 11.

If the precipitation is less, after the surface water falls into the water through cavity 11, solid impurities mixed in the surface water are filtered by the filter part 2 and accumulated in the first cavity channel, and the filtered surface water falls into the second cavity channel, so that the solid impurities are completely filtered; in the second cavity, the surface water is purified by the purifying element 3, so that dissolved components in the liquid are eliminated, and the purified surface water permeates into the soil matrix 300 through the drain hole 13, so that the dissolved components are completely purified, and the pollution to the soil matrix 300 is avoided.

If the precipitation is too big, filter 2 and filter solid impurity, the filter speed is very fast for surface water can be rapid get into the second chamber in the way, and the purification rate of purification piece 3 is slower in the second chamber way, and the part unpurified surface water can be followed supplementary infiltration hole 111 and infiltrated road 100 or the underground part in greenery patches 200, avoids influencing the filtration of filter 2 because of second chamber ponding, thereby preferentially guarantees to filter the solid impurity in the surface water.

Moreover, when solid impurities in the water through cavity 11 are cleaned after rain, as rainwater in the water through cavity 11 is discharged into the soil base 300 along the water discharge hole 13, the solid impurities fall on the top surface of the filter element 2, and the filter element 2 is removed and taken out, so that the cleaning of the solid impurities can be realized, and the implementation is very convenient.

In the above process, since the solid impurities in the surface water are stored in the first cavity and the liquid part of the surface water is discharged to the ground through the water discharge hole 13, the solid impurities are prevented from flowing into the greening area 200 along with the surface water, that is, the device protects the greening area 200.

Compared with the prior art, the utility model provides a pair of garden drainage ditch can play the guard action to afforestation district 200, can store solid impurity moreover, has alleviateed the working strength of cleaning process when retrieving impurity, and the surface water on road surface 100 carries solid impurity such as fallen leaves, disconnected branch and gushes into afforestation district 200 when effectively having solved the rainy that exists among the prior art, causes the technical problem of harm to afforestation district 200. That is to say, the garden drainage ditch provided by the utility model can completely filter solid impurities and completely purify dissolved components when the precipitation amount is small; when the precipitation is too big, can be preferentially guaranteed the filtration to solid impurity, can compromise the purification of dissolved composition to a certain extent simultaneously, avoid surface water to carry solid impurity and dissolved composition to pour into afforestation district 200, cause the harm to afforestation district 200.
