[0002] In the basement engineering, groundwater seeping into the terrace can cause adverse effects on the structure, affecting the normal use of the basement. In order to solve this problem, the existing technology often uses crushed stone as a drainage layer under the basement terrace, so that the seepage water can be discharged to the surrounding drainage ditch in time. At the same time, PVC pipes are pre-buried on the wall of the drainage ditch as a conduit to discharge water. However, this method often appears insufficient drainage capacity and pipe blockage in practical application, resulting in local water accumulation. Therefore, it is necessary to explore and develop more efficient drainage technology to improve the drainage efficiency of the drainage layer and ensure its normal use. UTILITY MODEL CONTENT

[0018] The technical scheme in the utility model embodiment will be described clearly and completely below with reference to the drawings in the utility model embodiment.
[0019] The embodiment discloses a basement drainage ditch drainage structure, like Figure 1As shown, the drainage ditch 4 is arranged along the wall 2 of the basement, the drainage ditch 4 is connected with the water collecting well, the ditch wall 3 of one side of the drainage ditch 4 is attached to the wall 2 of the basement, and the bottom of each side ditch wall 3 is provided with a drainage plate 5 with a height of 30mm. The drainage plate 5 in the embodiment adopts a drainage plate with concave-convex water permeable holes with a height of 30mm, the bottom of the drainage plate 5 is provided with a circular convex platform 6 at intervals, and the lower part of the drainage plate 5 is a reinforced concrete base layer 1. The outer side of the ditch wall 3 away from the wall 2 is provided with a gravel layer 8, and the height of the gravel layer 8 is lower than the height of the ditch wall 3. In the embodiment, the gravel layer 8 is paved by graded gravel with a maximum particle size of not greater than 30mm, so as to ensure better water permeability. When the drainage plate 5 is arranged, the water permeable holes on the drainage plate 5 are connected with the drainage ditch 4 and the gravel layer 8, one side of the circular convex platform 6 faces downward, so as to facilitate the drainage of water permeated from the gravel layer 8 into the drainage ditch 4, the side end surface of the drainage plate 5 is flush with the ditch wall 3, the drainage plate 5 near the gravel layer 8 extends from the bottom of the ditch wall 3 to form an extended section to the gravel layer 8, the length of the extended section is 200mm, and the extended section extends into the lower part of the gravel layer 8, so as to better drain the water permeated from the gravel layer 8 into the drainage ditch 4. In order to prevent the gravel and impurities in the gravel layer 8 from blocking the drainage channel at the bottom of the drainage plate 5, non-woven fabric 7 is laid on the outer surface of the ditch wall 3 adjacent to the gravel layer 8, the top surface of the extended section of the drainage plate 5, and the surface of the base layer 1 outside the drainage plate 5. The non-woven fabric 7 adopts polyester non-woven fabric, and the laying meets ≥100g / m 2 The gravel layer 8 is located on the upper part of the non-woven fabric 7.
