Detailed Description
The utility model will be described in detail below with reference to the following drawings: as shown in attached figures 1 and 2, the drainage core plate comprises a drainage core plate 1 and a filter membrane 2, wherein the drainage core plate 1 is made of a PVC material, the cross section of the drainage core plate 1 is a grid-shaped cross section, and a plurality of vertical drainage channels 3 are formed; the bottom of the drainage core plate part 1 is sleeved with a communicating plate boot 4, and the periphery of the communicating plate boot 4 is communicated with a plurality of drainage channels 3; the filter membrane 2 is wrapped around the drainage core plate 1 and around and at the bottom of the communicating plate boot 4, and the plurality of drainage channels 3 are communicated with the filter membrane 2; when fine particles in soft soil are accumulated on the drainage core plate 1 through the filter membrane 2, and part of the drainage channels 3 cannot be drained upwards, water in the silted channels can be gathered downwards into the communicating plate shoes 4 and then is drained upwards from the channels which are not silted, so that the drainage capacity of the drainage core plate 1 is enhanced.
The communicating plate boots 4 are PVC containers with sealed bottoms and opened tops, and the cross section area of the communicating plate boots 4 is larger than that of the drainage core plate part 1; the height of communicating plate boots 4 is 10 to 20cm, length is 2 to 4mm more than the cross section length of drainage core plate 1, the width is 6 to 8mm more than the cross section width of drainage core plate 1, all towards the long limit direction of communicating plate boots 4 because of drainage channel 3's infiltration mouth, only the infiltration mouth on both sides limit is towards the broadside direction of communicating plate boots 4, so through the width of above-mentioned communicating plate boots 4, length and the clearance setting between the drainage core plate 1, can make in the water drainage channel can assemble downwards in the communicating plate boots, and make the quick circulation of each drainage channel hydroenergy each other, drainage efficiency promotes greatly.
When the device works, due to the structure that the bottom of the communicating plate boot 4 is sealed and the top is opened, a water storage area can be formed at the bottom of the drainage core plate part 1; the water in each drainage channel 3 can seep downwards and converge into the water storage area, and the water in the water storage area can be selected to be discharged upwards along the drainage channel 3 with smaller on-way resistance; therefore, when some of the drainage channels 3 are clogged and cannot be drained upward, water in these drainage channels 3 can be collected downward into the communication plate shoes 4 and then flow out to the ground surface from other drainage channels 3 that are not clogged, thereby enhancing the drainage ability of the drainage core member 1.
