Description

Technical Field

[0001] The utility model belongs to the technical field of drainage ditches, in particular to drainage ditches of mountain roads. Background Art

[0002] Drainage ditch refers to the ditch that diverts water collected from side ditches, intercepting ditches and low-lying areas near roadbeds, farmlands and houses to outside the roadbeds, farmlands and houses. It is generally divided into two forms, one is cast-in-place and the other is prefabricated. In order to prevent blockage, water grates are installed on the top.

[0003] Among them, after searching, it was found that there is an application number of CN202223241935.8. When the device is in use, the heavier dust and garbage in the process of rainwater flowing through the concrete ditch can be intercepted in the collection tank and settled to form sludge. When cleaning is required, the ditch sealing plate at the connecting shaft can be rotated to open, and the card plate can be slid from the square tube into the card groove of the concrete ditch to support the ditch sealing plate, so that the ditch sealing plate can stand upright, which is convenient for staff to clean the concrete ditch. The collection tank can be lifted out of the shelf tank by hooking the pull ring, and the staff can uniformly collect and process the sludge and garbage collected in the collection tank. Such a drainage ditch structure does not need to remove the ditch sealing plate, which is more labor-saving and convenient to collect and remove the sludge inside the ditch, so that the efficiency of ditch sludge cleaning work can be effectively improved; Among them, the shortcomings are as follows:

[0004] When used in some mountainous areas, due to sharp bends or some straight roads, rainwater will carry branches and other debris and impact the side ditches. Ordinary prefabricated side ditches will be displaced due to the impact. At the same time, the water grate bears the filtering operation. As the amount of rainfall increases and as the accumulation of debris reaches a certain threshold, the water flow will impact other slopes, and in severe cases, landslides will occur. To address the above problems, a new type of side ditch structure needs to be designed. Utility Model Content

[0005] The purpose of the utility model is to provide a drainage ditch for a mountain highway in order to solve the above-mentioned problem.

[0006] The technical solution adopted by the utility model is as follows: a drainage ditch of a mountain highway includes a pressure plate and a drainage ditch. A drainage ditch is arranged below the pressure plate, and a pre-buried pipe column is pre-buried on the outer side of the drainage ditch. A connecting hole is arranged on the surface of the pressure plate, and an anchor nail passes through the connecting hole to be connected with the pre-buried pipe column, and an anchor nail is arranged inside the pre-buried pipe column; convex strips and positioning recesses are integrally arranged on the bottom of the pressure plate and the upper edge of the drainage ditch, and a buckle surface is integrally arranged on the step of the drainage ditch; the buckle surface is divided into concave and convex shapes, which are arranged in a fitting manner.

[0007] A filtering structure is set above the pressure plate to prevent debris from affecting drainage, and a fixing structure is set at the bottom of the drainage ditch for easy installation;

[0008] The filtering structure includes water grating bars, grooves and oblique baffles. The surface of the pressure plate is located above the drainage ditch opening and is integrated with water grating bars. One side of the pressure plate is integrated with a groove next to the water grating bars. The groove is rotatably connected with an oblique baffle bar.

[0009] The fixed structure includes columns, inverted nails, springs, and expansion nails. The bottom of the drainage ditch is integrated with columns, and the columns are hollow. Inverted nails are set through the side walls of the columns, and there are springs between the inverted nails and the columns. Expansion nails are movably connected inside the columns. The columns are conical in shape, and there are several inverted nails, which are inclined on the surface of the columns.

[0010] Wherein, the convex strip and the concave groove are matched with each other.

[0011] There are several inclined baffles, which are arranged in parallel, and the rotation angle of the inclined baffles is 160°.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the utility model, the inclined baffle bar is turned up to block the debris first, so as to prevent the debris from accumulating on the water grate bar, thereby improving the anti-blocking ability of the whole device. When the inclined baffle bar is not needed, it can be placed inside the groove, so that the anti-blocking threshold of the whole ditch is increased.

[0014] 2. In the utility model, the plug posts are conically set, and the number of inverted nails is several, which are set obliquely on the surface of the plug posts. When the plug posts are inserted into the ground, the drainage ditch can be made more stable. At the same time, because the pressure plate is fixed by the anchor nails, the convex strips are connected with the grooves, so that the pressure plate and the drainage ditch form a whole, thereby improving the strength.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the utility model:

[0022] Reference Figure 1-4 The drainage ditch of the mountain highway includes a pressure plate 2 and a drainage ditch 3. The drainage ditch 3 is arranged below the pressure plate 2. A pre-buried pipe column 1 is pre-buried outside the drainage ditch 3. An anchor 101 is arranged inside the pre-buried pipe column 1. A connection hole is arranged on the surface of the pressure plate 2. The anchor 101 passes through the connection hole and is connected to the pre-buried pipe column 1. A convex strip 201 and a positioning recess 301 are integrally arranged on the bottom of the pressure plate 2 and the upper edge of the drainage ditch 3. A buckle surface 302 is integrally arranged on the drainage ditch 3. The buckle surface 302 is divided into a concave and convex shape and is arranged in a fitting manner. Multiple sections of the drainage ditch 3 can be connected by using the buckle surface 302, and the concave and convex shape can ensure the sealing of the connection.

[0023] A filtering structure is provided above the pressure plate 2 to prevent debris from affecting drainage, and a fixing structure is provided at the bottom of the drainage ditch 3 to facilitate installation;

[0024] The filtering structure includes a water grate bar 203, a groove 202 and an oblique retaining bar 6. The surface of the pressure plate 2 is located above the opening of the drainage ditch 3 and is integrally provided with a water grate bar 203. One side of the pressure plate 2 is integrally provided with a groove 202 located next to the water grate bar 203. The groove 202 is rotatably connected with an oblique retaining bar 6.

[0025] The fixed structure includes a plug post 4, a reverse nail 401, a spring 402, and an expansion nail 5. The bottom of the drainage ditch 3 is integrated with the plug post 4, and the plug post 4 is hollow. The side wall of the plug post 4 is penetrated by the reverse nail 401, and a spring 402 is arranged between the reverse nail 401 and the plug post 4. The plug post 4 is movably connected with the expansion nail 5. The plug post 4 is conical, and there are several reverse nails 401, which are inclined on the surface of the plug post 4. When the plug post 4 is inserted into the ground, the drainage ditch 3 can be made more stable and can withstand the impact force of the water flow. At the same time, inserting the expansion nail 5 into the plug post 4 can make the reverse nail 401 extend, thereby further improving the stability.

[0026] Furthermore, the convex strip 201 and the concave groove 202 are matched with each other. Since the pressure plate 2 is fixed by the anchor 101, the convex strip 201 is connected with the concave groove 202, so that the pressure plate 2 and the drainage ditch 3 form a whole, thereby improving the strength.

[0027] Furthermore, there are several inclined baffle bars 6, which are arranged in parallel, and the rotation angle of the inclined baffle bars 6 is 160°. When a large water flow appears, the water flow will carry the debris and impact it. At this time, the inclined baffle bars 6 can be flipped up to prevent the debris from accumulating on the water grate bars 203, thereby improving the anti-blocking ability of the entire device.

[0028] Working principle: first, embed the pre-buried pipe column 1, and then insert the drainage ditch 3 into the ground. Since the plug column 4 is set in a conical shape, there are several inverted nails 401, which are set obliquely on the surface of the plug column 4. When the plug column 4 is inserted into the ground, the drainage ditch 3 can be made more stable, so that it can withstand the impact of the water flow. At the same time, inserting the expansion nail 5 into the plug column 4 can make the inverted nail 401 extend, further improving the stability. Then, cover the drainage ditch 3 with the pressure plate 2. There are connection holes on the surface of the pressure plate 2. The anchor nail 101 penetrates the surface of the pressure plate 2. It is connected to the embedded pipe column 1 through the connecting hole, and the convex strip 201 and the groove 202 are matched. Since the pressure plate 2 is fixed by the anchor nail 101, the convex strip 201 is connected with the groove 202, so that the pressure plate 2 and the drainage ditch 3 form a whole, thereby improving the strength. Finally, when a larger water flow appears, the water flow will carry the debris with it for impact. At this time, the oblique baffle 6 can be turned up, and the oblique baffle 6 can first block the debris to prevent the debris from accumulating on the water grate bar 203, thereby improving the anti-blocking ability of the entire device.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
