[0024] The bottom of the waterfall upper structure 2 is fixedly connected with a square groove, and the top of the waterfall bottom layer 1 is fixedly connected with a docking square groove that matches the square groove, and the docking square groove is clearance-matched with the direction groove. The square notch at the bottom of the waterfall upper structure 2 matches the notch size at the top of the waterfall upper structure 2, and is used for stacking multiple waterfall upper structures 2.

[0025] The limiting plate 3 is composed of a special-shaped butt joint 31 and a plurality of slots 32 . The slots 32 are fixed at the bottom of the special-shaped butt joint 31 , and a slot matching with the slots 32 is provided at the mouth of the drop well upper structure 2 .

[0026] An inspection port matching the resin concrete drainage ditch system is set, and the main body is a layered design, which is convenient for selecting the number of layers according to different usage scenarios and different depth requirements to meet the needs. A dirt basket 5 is installed inside, and the dirt basket 5 is placed on a specially designed boss inside the main body of the upper structure 2 of the drop well, which is easy to place and simple to maintain.

[0027] like Figure 3 and 4 A second embodiment is shown, which mainly differs from the first embodiment in that the quick installation and opening component 6 includes a slide groove 61 opened on the front side of the cover plate 4, and a buckle 62 is slidably connected to the inner surface of the slide groove 61, and the buckle 62 can slide back and forth, and a limiting spring 63 is fixedly connected between the back side of the buckle 62 and the back side of the inner wall of the slide groove 61, and a buckle slot 610 cooperating with the buckle 62 is fixedly connected to the bottom of the limiting plate 3, and two left and right downwardly concave grooves 64 are arranged at the bottom of the inner side of the two limiting plates 3, and a return spring 65 is fixedly connected to the bottom of the inner wall of the front groove 64, and the other end of the return spring 65 is fixedly connected to a support plate 66, and a fixing rod 67 is fixedly connected between the left and right sides of the inner wall of the rear groove 64, and two left and right protrusions 68 are fixedly connected to the rear of the bottom of the cover plate 4, and an arc groove 69 cooperating with the fixing rod 67 is opened at the bottom of the protrusion 68.
