Description

Technical Field

[0001] This invention relates to a drainage ditch debris trapping system and construction method, belonging to the field of drainage technology. Background Technology

[0002] Before rainwater is directly discharged into rivers, lakes, and reservoirs, it needs to undergo preliminary purification. Currently, seasonal rainwater commonly found in highway and urban community drainage ditches is collected using a combination of sedimentation and interception to collect debris such as branches and leaves. Existing facilities mostly use fixed vertical grates, which are prone to clogging when there is a large amount of initial debris or when branches and leaves are mixed, affecting drainage efficiency. The interception effect of fine debris mainly depends on the mesh size of the collection grate, requiring a balance between flow capacity and debris interception effect. In addition, existing debris interception facilities generally rely on manual maintenance, which is labor-intensive. Some solutions propose using a motor to drive a lever in front of the filter screen to reciprocate and reduce clogging, but the layout of the electromechanical system is often difficult to implement in practice. If the collected plant debris can be easily used for farmland composting, it will help combine highway drainage ditch maintenance with improving farmland soil fertility, thereby supporting the construction of high-standard farmland. At the same time, with the development of drone technology, there is also a need for a debris interception device that is easy to lift, install, and dismantle to meet the needs of modern maintenance. Summary of the Invention

[0003] The purpose of this invention is to provide a drainage ditch slag interception system and construction method. By arranging a slag interception system, including at least a primary slag interception body and a floating slag interception body, in the middle and lower reaches of the drainage ditch, the system can effectively intercept moving slag in seasonal rainwater ditches, achieve preliminary purification of runoff, and is easy to install and maintain.

[0004] To achieve the above objectives, the present invention is implemented using the following technical solution.

[0005] On one hand, the present invention provides a drainage ditch debris trapping system, comprising:

[0006] The initial slag interception body is configured as a slag storage body with an open opening and a water filtering channel, and is arranged at the bottom of the ditch in the direction of incoming water.

[0007] Floating slag interceptors are arranged at intervals in the ditch after the initial slag interceptor, including fixed interceptors with a set interval from the bottom of the ditch or floating interceptors that float up and down according to the water level.

[0008] When the slag interceptor is a fixed interceptor, the top of the initial slag interceptor is higher than or level with the bottom of the fixed interceptor.

[0009] Optionally, the system further includes a slag guide disposed between the initial slag interceptor and the floating slag interceptor;

[0010] The guide body is located in the upper middle part of the ditch, and its bottom end is aligned with the bottom end of the fixed interceptor body. It is used to regulate the direction of long slag or to block long slag and long block-shaped objects.

[0011] Optionally, the initial slag interceptor includes a mesh frame adapted to a groove at the bottom of the ditch and a cover net for covering the mesh frame with an opening reserved in the direction of incoming water, the cover net curving upwards in the direction of incoming water.

[0012] The cover net and the frame are combined into a rigid whole, and the upper surface of the cover net is equipped with a hanging ring. The front end of the cover net at the opening is bent upward.

[0013] Optionally, the slag guide body includes a longitudinally upright thin plate suspended inside the ditch and a first transverse fixing member for fixing the thin plate;

[0014] The first transverse fixing member has a lifting ring on its upper surface and is fitted into a first limiting mechanism located at the top of both sides of the ditch. The first limiting mechanism has an opening facing the direction of incoming water.

[0015] Optionally, the thin plate is configured as at least one piece or multiple pieces staggered front to back to evenly divide the channel laterally, which is stepped and points in the direction of water flow and has a concave-convex structure at the lower step.

[0016] Optionally, the floating interceptor includes: a window frame and a net for covering the window frame;

[0017] The window frame is a lightweight window frame, including a wooden frame, a foam frame, or a frame with an airbag, which is intermittently engaged in the sliding grooves of the ditch sidewall;

[0018] The net bag is a nylon net bag.

[0019] Optionally, the fixed interceptor is a silo suspended in the upper part of the ditch, with its bottom and tail ends capable of filtering water.

[0020] Optionally, the top of the silo is fixed to a second transverse fixing member with a lifting ring on the upper surface, and the second transverse fixing member is embedded in a second limiting mechanism located at the top of both sides of the ditch and with the opening facing the direction of water flow.

[0021] In a second aspect, the present invention provides a construction method for a drainage ditch debris-trapping system, the drainage ditch debris-trapping system based on any one of the first aspects comprising:

[0022] S1. In the middle and lower reaches of the ditch, at least two adjacent locations are marked at intervals, wherein the location located in the direction of incoming water is the location of the initial slag interception body, and the location located in the direction of outgoing water is the location of the floating slag interception body.

[0023] S2. A groove is dug at the bottom of the ditch at the location of the initial slag interception body and an initial slag interception body adapted to the groove is hoisted. The groove and the initial slag interception body are one set or multiple sets spaced apart.

[0024] S3. At the top of both sides of the ditch where the sludge interceptor is located, a second limiting mechanism with the opening facing the direction of the incoming water is installed to fix the top of the fixed interceptor to the second horizontal fixing member, and the second horizontal fixing member is inserted into the second limiting mechanism from the direction of the incoming water.

[0025] When a fixed interceptor is replaced with a floating interceptor, a sliding groove is made on the side wall of the ditch corresponding to the window frame of the floating interceptor, and the window frame is fitted into the sliding groove with a gap.

[0026] Optionally, the method further includes setting a slag guide position between the initial slag interception body and the floating slag interception body;

[0027] At the top of both sides of the ditch where the slag guide is located, a first limiting mechanism with an opening pointing in the direction of incoming water is installed; a vertically erected thin plate is fixed below the first horizontal fixing member to form a slag guide, and the first horizontal fixing member is inserted into the first limiting mechanism from the direction of incoming water to limit the slag guide.

[0028] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0029] This invention utilizes a slag interception system deployed in the downstream of drainage ditches. The system employs a segmented structure of initial slag interception bodies and floating slag interception bodies to intercept different types of slag, effectively intercepting moving slag within seasonal rainwater ditches and achieving initial purification of the runoff. The initial slag interception body, located at the bottom of the ditch in the direction of incoming water, intercepts stones and leaf debris, while the floating slag interception body collects floating slag, achieving classified interception of different slag types. Furthermore, the floating slag interception body can be either a fixed or floating type. Fixed interception bodies are easier to install and offer better stability; floating interception bodies, when the water level is low, can further intercept escaped slag that the initial slag interception body failed to catch, and when the water level is high, they provide a larger flow channel compared to fixed interception bodies. When the system includes slag guide bodies, it can effectively straighten long slag or block some long slag and long block-shaped slag, reducing the pressure and clogging risk of subsequent floating slag interception. Furthermore, the segmented structure of this system is equipped with lifting rings, which facilitates hoisting and maintenance, and the collected slag is easy to lift out, which can be used for composting or infiltration structure in green spaces.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0036] Example 1

[0037] This embodiment describes a drainage ditch debris trapping system that is easy to maintain, such as... Figure 1 , Figure 2 As shown, the system includes an initial slag interceptor located at the inlet water end and a floating slag interceptor located at the outlet water end, as well as a slag guide located between the two. Of course, the slag guide may not be included; this embodiment uses a slag interception system equipped with a slag guide to comprehensively illustrate the specific structure and function of the invention.

[0038] The initial slag interception body is configured as a slag storage body with an opening and a water filtration channel, positioned at the bottom of the ditch in the direction of incoming water. It consists of a mesh frame 1 and a cover net 2. The mesh frame 1 fits into a pre-cut groove at the bottom of the ditch. Specifically, the groove is a rectangular prism, with a width matching the width of the ditch and a length greater than the width. The cover net 2 has an opening and slopes upwards to cover the mesh frame 1, with the opening located in the direction of incoming water, extending longitudinally for 25cm to 40cm. Both the mesh frame 1 and the cover net 2 can be made of steel and welded together. A lifting ring is provided above the cover net 2 for easy hoisting during construction and maintenance. Notably, the front end of the cover net 2 at the opening is bent upwards, specifically processed into a comb-like structure to intercept linear floating debris and leaf debris in the water.

[0039] Consider a special case where, when the water level is below the top of the cover net 2, all debris is collected into the net frame 1 or intercepted by the inclined cover net 2, but this is rare during the rainy season.

[0040] During the rainy season (especially with continuous rainfall), the bottom of drainage ditches extends for tens to hundreds of meters. Runoff flows from high to low elevations, and the initial water depth is shallow. Leaf debris is pushed along the ditch bottom with friction. The initial debris interceptor at the bottom of the ditch is trapped in the mesh frame 1, helping to reduce subsequent clogging and interception pressures. With the pre-positioned initial debris interceptor, the impact of heavy sedimentary deposits blocking the water passage at the bottom, which is detrimental to drainage, is reduced.

[0041] The slag guide body is installed in the upper part of the ditch after the initial slag interception body. It includes a longitudinally upright thin plate 3 suspended inside the ditch and a first transverse fixing member 4 (a rectangular plate) for fixing the thin plate. The upper surface of the first transverse fixing member 4 is provided with a lifting ring, which is embedded in a first limiting mechanism located at the top of both sides of the ditch. The first limiting mechanism has an opening facing the direction of incoming water. In this embodiment, the first limiting mechanism uses an L-shaped nail (not shown in the figure, but other structures that can achieve the limiting function described in this embodiment can also be used). It is inserted into the top of both sides of the ditch, leaving an opening facing the direction of incoming water. The first transverse fixing member 4 is embedded in the gap left by the nail to achieve the limiting function.

[0042] Specifically, the thin plates are configured as at least one or multiple plates staggered front to back to evenly divide the channel laterally, which are stepped and point in the direction of water flow and have a concave-convex structure at the lower step.

[0043] The guide body is used to regulate the direction of long slag rods, preventing them from flowing laterally into the drainage direction and causing blockages, thus facilitating subsequent collection. The thin plate 3 can adjust the direction of the long slag rods to make them nearly straight. In addition, the guide body can also block some long slag rods and floating long, blocky objects. Specifically: on the one hand, long slag rods longer than the width of the ditch will be stuck against the guide body because both ends are supported (one end against the guide body and the other end against the rough sidewall of the ditch); on the other hand, forked long slag rods can be secured to the front end of the guide body by their forks, thus gaining support; and plastic blocks may be stabilized due to symmetrical or asymmetrical obstruction in the middle. In particular, when two or three thin plates 3 evenly divide a wider ditch, it is easier for long-stemmed slag to obtain support and embedment similar to a culvert opening. The rough surface adjacent to the ditch sidewall facilitates embedding. Slag embedded in front of the guide slag body can be manually maintained and removed later. Slag embedded between the thin plates 3 can be lifted out of the guide slag body and removed later. Of course, this is an uncommon situation. In actual engineering, the gap between the thin plates 3 is often sufficient to allow long-stemmed slag to pass through and in a straight direction.

[0044] In particular, the concave and convex ends of the thin plate 3 are convenient for embedding or blocking long rods and long block-shaped slag at different water levels and cross sections, and the concave and convex shapes at the lower front end are also convenient for strengthening the stability of the plastic block.

[0045] The slag interceptors are spaced out in the upper part of the ditch behind the slag guide body. In this embodiment, a fixed interceptor is selected.

[0046] When the sludge interceptor is a fixed interceptor, silo 7 is selected as the interceptor (a wire basket can also be used). It has a set interval with the bottom of the ditch, specifically 2 / 5 to 1 / 2 of the ditch depth, to ensure the water filtration channel below. The top of silo 7 is fixed to a second transverse fixing member 4.1 with lifting rings on its upper surface. The second transverse fixing member 4.1 can be a rectangular plate. The rectangular plate is embedded in a second limiting mechanism located at the top of both sides of the ditch with its opening facing the incoming water direction. The second limiting mechanism uses L-shaped nails (not shown in the figure, but used to limit the installation of the rectangular plate). The rectangular plate is inserted from the opening direction. In subsequent maintenance, the rectangular plate can be moved longitudinally first and then lifted vertically. The second limiting mechanism is located behind the first limiting mechanism (in the outgoing water direction).

[0047] Fixed interceptors can better collect high-floating slag and reduce the pressure on floating slag interceptors, and also facilitate mechanized maintenance.

[0048] In the system described in this embodiment, the top of the initial slag interceptor (the upper end of the cover net 2) is not lower than the bottom of the slag guide (the lower end of the thin plate 3) and the bottom of the fixed interceptor (the lower end of the silo 7), and the bottom of the slag guide (the lower end of the thin plate 3) and the fixed interceptor (the lower end of the silo 7) are level with each other. This design can effectively intercept different types of slag within the entire cross-section of the incoming water.

[0049] It should be noted that when there is no slag guide, the front-to-back and vertical relationships of other structures in the drainage ditch remain unchanged.

[0050] The working principle of the system described in this embodiment is as follows: the initial slag interceptor in the direction of incoming water acts as a low-level interceptor, and the floating long slag is collected in the direction of outgoing water by the slag guide in a straight direction; or long slag and long blocky slag are blocked by the slag guide, thus achieving the classification and interception of different slag types. When the slag guide is not present, the floating slag will be directly collected into the fixed interceptor. The specific method depends on the working conditions of different ditches. In ditches with fewer long slag, the efficient classification and interception of different slag types can be achieved without using a slag guide.

[0051] Example 2

[0052] The only difference between this embodiment and Embodiment 1 is that the fixed interceptor is replaced with a floating interceptor, such as... Figure 3 and Figure 4 As shown, the following is a description of the slag interception system, which includes an initial slag interception body, a slag guiding body, and a floating interception body:

[0053] The structure and position of the initial slag interceptor and the slag guide in the ditch are the same as in Example 1, and will not be repeated here. However, one point is that the top of the initial slag interceptor (the top of the cover net 2) is not lower than the bottom of the slag guide (the bottom of the thin plate 3).

[0054] The floating interceptor includes a window frame 6 and a net bag 5 (50-100cm in length) for covering the window frame 6. The window frame 6 is a lightweight frame, including a wooden frame, a foam frame (PP foam, EVA foam), or a frame with air bladders, which is intermittently engaged in sliding grooves in the sidewall of the ditch. The net bag 5 is a nylon net bag. In practical applications, a longitudinally connected empty plastic bottle can be attached inside the nylon net bag to achieve a semi-submersible, semi-floating state for the floating interceptor. Alternatively, the net bag 5 may be a wire mesh bag equipped with a float (mesh size 10-15mm).

[0055] It should be noted that when there is no slag guide, the front-to-back and vertical relationships of other structures in the drainage ditch remain unchanged.

[0056] Its advantages are that the floating interceptor can move up and down with the water level. When the water level is low, it can further intercept the escaped slag that the initial slag interceptor failed to intercept. And when the water level is too high, it can ensure a larger water passage channel compared with the fixed interceptor.

[0057] Example 3

[0058] Based on the drainage ditch slag interception system described in Embodiment 1 or Embodiment 2, this embodiment introduces a construction method for a drainage ditch slag interception system. The system includes an initial slag interception body, a slag guiding body, and a floating slag interception body. The structures of each part are as described in Embodiment 1 or Embodiment 2, and will not be repeated here. The construction method includes:

[0059] Step 1: In the middle and lower reaches of the ditch, mark three adjacent locations at intervals. The location in the direction of incoming water is the initial slag interception body, the location in the direction of outgoing water is the floating slag interception body, and the location in between is the slag guiding body.

[0060] Step 2: Dig a groove at the bottom of the ditch where the initial slag interceptor is located, and use lifting rings to hoist the initial slag interceptor that fits the groove; the initial slag interceptor consists of a pre-welded mesh frame 1 and a cover mesh 2. The groove and the initial slag interceptor are in one set or multiple sets spaced apart.

[0061] At the top of both sides of the ditch where the slag guide is located, a first limiting mechanism (L-shaped nail) with the opening pointing in the direction of incoming water is installed; a vertical thin plate 3 (which can be one piece or multiple pieces staggered front and back) is fixed below the first horizontal fixing member 4 to form a slag guide, and the first horizontal fixing member 4 is inserted into the first limiting mechanism from the direction of incoming water to limit the slag guide.

[0062] At the top of both sides of the ditch where the slag interceptor is located, a second limiting mechanism (L-shaped nail) with the opening pointing in the direction of incoming water is installed to fix the top of the fixed interceptor (silo 7) to the second horizontal fixing member 4.1, and the second horizontal fixing member 4.1 is inserted into the second limiting mechanism from the direction of incoming water.

[0063] Another scenario: When the fixed interceptor is replaced with a floating interceptor, a sliding groove is made on the side wall of the ditch corresponding to the window frame 6 of the floating interceptor (the top of the sliding groove has a limit to ensure that the floating interceptor will not float out of the ditch). The window frame 6 is then inserted into the sliding groove with a gap. The window frame 6 and the net bag 5 are also pre-installed to form a floating interceptor.

[0064] It is worth noting that the installation order of the initial slag interceptor, slag guide, and floating slag interceptor is not fixed and can be adjusted according to the construction site. When there is no slag guide, the front-to-back and vertical relationships of the other structures in the drainage ditch remain unchanged.

[0065] In summary, the present invention can effectively intercept moving debris in seasonal rainwater ditches, achieving preliminary purification of runoff. It is also convenient for hoisting and maintenance; the collected debris can be easily removed and used for composting or infiltration structures within green spaces, providing a new solution for debris collection in drainage ditches.
