AI Technical Summary
The existing rainwater collection ditches structures do not collect rainwater during moderate or light rain, and it is difficult to effectively classify solid debris during heavy rain, resulting in solid debris entering the reservoir.
A rainwater collection ditch structure including main trench, hidden trench and sub-ditch was designed. There are hidden trench and sub-ditch with a cross-section smaller than the main trench, both with cover plates and water-through holes and water-through holes. The diameter and width of the grooves increase by size, and the fiberglass prefabricated parts are used to form a U-shaped cross-section.
In light rain or moderate rain, the rainwater collection efficiency is improved, and the grading screening function of the water-through holes is effectively removed from solid debris during heavy rain to prevent it from entering the reservoir.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rural water treatment, and more specifically to a rainwater collection ditch structure. Technical Background
[0002] The existing rainwater collection ditch structures are all common single main ditch structures. The main ditch has a large cross-section and a wide bottom. It stores too much water and can only form confluence when the rainfall reaches a certain level. This rainwater collection ditch structure collects rainwater more fully during heavy rain, but cannot play a good role in collecting rainwater during moderate or light rain. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a rainwater collection ditch structure, and the technical solution it adopts is: a rainwater collection ditch structure, which includes a main ditch and a main ditch cover plate, and is characterized in that: a dark ditch with a smaller cross-section than the main ditch is also arranged in the main ditch, and the dark ditch is provided with a dark ditch cover plate, and both the main ditch cover plate and the dark ditch cover plate are provided with water holes.
[0004] The further technical features of the utility model are:
[0005] A secondary ditch with a cross section larger than that of the ditch and smaller than that of the main ditch is provided between the main ditch and the culvert. The secondary ditch is provided with a secondary ditch cover plate, which is also provided with water holes.
[0006] The water holes on the main ditch cover plate and the dark ditch cover plate are both circular water holes, and the diameter of the water holes on the main ditch cover plate is larger than the diameter of the water holes on the dark ditch cover plate.
[0007] The water holes on the main ditch cover plate and the dark ditch cover plate are both strip-shaped water holes, and the width of the water holes on the main ditch cover plate is greater than the width of the water holes on the dark ditch cover plate.
[0008] The water holes on the main ditch cover, the dark ditch cover and the auxiliary ditch cover are circular water holes, and the diameter of the water holes on the main ditch cover is larger than the diameter of the water holes on the auxiliary ditch cover, and the diameter of the water holes on the auxiliary ditch cover is larger than the diameter of the water holes on the dark ditch cover.
[0009] The water holes on the main ditch cover, the dark ditch cover and the auxiliary ditch cover are all strip-shaped water holes, and the width of the water holes on the main ditch cover is greater than the width of the water holes on the auxiliary ditch cover, and the width of the water holes on the auxiliary ditch cover is greater than the width of the water holes on the dark ditch cover.
[0010] The culvert is a prefabricated fiberglass part with a U-shaped cross section.
[0011] The beneficial effects of the utility model are:
[0012] In the utility model, since the main ditch is also provided with a dark ditch with a smaller cross section than the main ditch, rainwater first collects from the main ditch to the dark ditch, and the dark ditch has a smaller cross section and a narrower bottom, less water storage and is easy to form confluence, so it can also play a good role in collecting rainwater during light or moderate rain. In addition, the dark ditch and the main ditch are both provided with a cover plate, and the main ditch cover plate and the dark ditch cover plate are both provided with water holes, and the water holes on the dark ditch cover plate are smaller than the water holes on the main ditch cover plate, so that solid debris washed into the ditch during heavy rain can be graded and screened and regularly removed to prevent more solid debris from entering the reservoir. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of the first embodiment of the utility model;
[0014] Figure 2 It is a structural schematic diagram of the second embodiment of the utility model;
[0015] Figure 3 It is a structural schematic diagram of the third embodiment of the utility model. DETAILED DESCRIPTION
[0016] The utility model is described in more detail below in conjunction with the accompanying drawings. Embodiment 1
[0017] Reference Figure 1 A rainwater collection ditch structure includes a main ditch 1 and a main ditch cover 11, wherein a U-shaped culvert 2 having a smaller cross section than the main ditch is further provided in the main ditch, a culvert cover 21 is provided in the culvert 2, and water holes 3 are provided on both the main ditch cover 11 and the culvert cover 21. In this embodiment, the water holes 3 on the main ditch cover 11 and the culvert cover 21 are both circular water holes, and the diameter of the water holes on the main ditch cover 11 is larger than the diameter of the water holes on the culvert cover 21.
[0018] Since the main ditch 1 is also provided with a culvert 2 having a smaller cross section than the main ditch, rainwater firstly collects from the main ditch 1 to the culvert 2. The culvert 2 has a smaller cross section and a narrower bottom, stores less water and is easy to form a confluence, so it can also play a good role in collecting rainwater during light or moderate rain. In addition, both the culvert 2 and the main ditch 1 are provided with a cover plate, and both the main ditch cover plate 11 and the culvert cover plate 21 are provided with circular water holes 3, and the diameter of the water holes on the culvert cover plate 21 is smaller than that on the main ditch cover plate 11, so that solid debris washed into the ditch during heavy rain can be graded and screened and regularly removed to prevent more solid debris from entering the reservoir. Embodiment 2
[0019] Reference Figure 2In this embodiment, the cross-section of the culvert 2 is U-shaped, and a secondary ditch 4 with a cross-section larger than the cross-section of the culvert and smaller than the cross-section of the main ditch is provided between the main ditch 1 and the culvert 2. The secondary ditch is provided with a secondary ditch cover 41, and the secondary ditch cover 41 is also provided with a water hole 3; the water holes 3 on the main ditch cover 11, the culvert cover 21 and the secondary ditch cover 41 are circular water holes, and the diameter of the water holes on the main ditch cover 11 is larger than the diameter of the water holes on the secondary ditch cover 41, and the diameter of the water holes on the secondary ditch cover 41 is larger than the diameter of the water holes on the culvert cover 21, so that the effect of grading and screening solid debris washed into the ditch during heavy rain will be better. Embodiment 3
[0020] Reference Figure 3 In this embodiment, what is different from Embodiment 2 is that the water holes 3 on the main ditch cover 11, the dark ditch cover 21 and the auxiliary ditch cover 31 are all strip-shaped water holes, and the width of the water holes on the main ditch cover 11 is greater than the width of the water holes on the auxiliary ditch cover 41, and the width of the water holes on the auxiliary ditch cover 41 is greater than the width of the water holes on the dark ditch cover 21.
[0021] In practical applications, the culvert preferably uses fiberglass prefabricated parts, which is more conducive to the rapid construction of the ditch.
