Description

Technical Field

[0001] The utility model belongs to the field of municipal related technical fields, in particular to a municipal highway drainage channel. Background Art

[0002] In farmland irrigation, water from rivers is often used to introduce water into farmland through "ditches" dug on the ground, that is, canals. Canals are artificially dug waterways, divided into main canals and branch canals. Main canals and branch canals are generally built with stone or cement. On existing municipal roads, canals are usually set up on both sides of the road, mainly for draining rainwater or sewage, etc., also called drainage canals, but as far as the current drainage canals are concerned, there are still the following disadvantages:

[0003] 1. Drainage channels are mainly used for drainage, especially during heavy rains. Some roads will have covers on the channels, and there are also direct open-air channels. Such channels usually accumulate a lot of debris over time, and even become unusable for drainage. Especially for channels on mountain roads, subsequent cleaning is also more troublesome;

[0004] 2. When the rainfall is heavy, the drainage channel may even be filled up. If there are debris, it is more likely to fill up the channel and even cause backflow, so this problem needs to be avoided;

[0005] 3. Secondly, for prefabricated canals, they all need to be spliced ​​together, unlike the one-piece formwork casting, which requires the stability of the connection;

[0006] 4. Finally, for canals that usually have covers, the covers are directly placed on the canals. However, during long-term use, factors such as road vibration and human trampling may cause the covers to shift and no longer be able to be placed on the canals to seal them. Utility Model Content

[0007] The utility model aims to provide a municipal highway drainage channel. By arranging a drainage channel, a primary partition, a secondary partition, a grille, a cover plate, an anti-backflow baffle plate, a connector and a limit column, the utility model solves the problems that open-air water channels are easily blocked and difficult to clean; heavy rainfall easily causes backflow in the water channel, the connection of the prefabricated water channel is not stable enough, and the water channel cover plate is easily displaced due to road vibration.

[0008] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0009] The utility model is a municipal highway drainage channel, comprising a drainage channel 1, a cover plate 1, a drainage channel 2, a connecting piece and an anti-backflow baffle plate, wherein the ends of the drainage channel 1 and the drainage channel 2 close to each other are overlapped in the inner cavity of the connecting piece, the upper end surface of the drainage channel 1 is covered with a cover plate 1, and the end of the drainage channel 1 away from the drainage channel 2 is fixed with a sealing plate;

[0010] An L-shaped primary partition is fixed in the inner cavity of the drainage channel 1, and a secondary partition adapted to its cross-sectional size is also fixed in the inner cavity of the drainage channel 1, the secondary partition is located on the side of the primary partition away from the sealing plate, and base blocks are fixed on the two oblique inner walls of the drainage channel 1 on the side of the secondary partition away from the primary partition, and an anti-backflow baffle is rotatably connected between the opposite surfaces of the two base blocks;

[0011] A grille is fixed in the opening in the cover plate 1.

[0012] Furthermore, the bottom surface of the cover plate 1 at one end of the grille is fixed with reinforcement strips distributed at equal intervals; the length of the cover plate 1 is greater than the length of the drainage channel 1, and the width of the cover plate 1 is greater than the maximum width of the drainage channel 1.

[0013] Furthermore, the two long sides of the cover plate 1 are provided with equally spaced limiting holes, and limiting columns matching the number of limiting holes are fixed on both sides of the upper end of the drainage channel 1, and the limiting columns pass upward through the limiting holes vertically corresponding to them.

[0014] Furthermore, the outer side surface of the drainage channel 1 is fixed with reinforcing ribs distributed at equal intervals, the upper end cover of the drainage channel 2 is provided with a cover plate 2, and the overall size of the cover plate 2 is equal to the overall size of the cover plate 1; the structural dimensions of the drainage channel 1 and the drainage channel 2 are the same.

[0015] Furthermore, two symmetrical slots are provided in the connecting member, and the adjacent ends of the drainage channel 1 and the drainage channel 2 are respectively overlapped in a slot adjacent thereto.

[0016] Furthermore, the long side surface of the primary partition is provided with through holes one distributed in a rectangular array, and the secondary partition is provided with through holes two distributed at equal intervals, and the inner diameter of the through hole two is smaller than the inner diameter of the through hole one.

[0017] Furthermore, the upper parts of the two side surfaces of the backflow prevention baffle are rotatably connected to the base block, and a limiting protrusion is fixed on the inner bottom of the drainage channel on one side of the backflow prevention baffle close to the secondary baffle.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model solves the problem that open-air water channels are easily blocked and difficult to clean by arranging drainage channel 1, primary partition, secondary partition, grille and cover plate 1; the traditional open-air water channel structure is changed, a cover plate 1 is added and arranged on drainage channel 1, and three-stage filtering treatment is performed by grille, primary partition and secondary partition to prevent a large amount of impurities from entering drainage channel 2. Once the grille, primary partition and secondary partition are blocked, it is only necessary to open cover plate 1 and clean the debris in drainage channel 1. Multi-stage filtration can ensure that there will not be too much debris in subsequent drainage.

[0020] 2. The utility model solves the problem of backflow in the canal caused by heavy rainfall by providing an anti-backflow baffle. After the rainwater passes through the grille, the primary baffle and the secondary baffle, it will impact the anti-backflow baffle in the drainage channel 1, causing it to tilt, and the rainwater passes from underneath it. When too much water accumulates in the drainage channel 2, there may be a surge phenomenon, resulting in backflow, etc. At this time, the water flow will reversely impact the anti-backflow baffle. The anti-backflow baffle is limited by the limiting protrusion and can only be set vertically, which can ensure that the water flow will not re-enter the drainage channel 1 on the side of the anti-backflow baffle close to the secondary baffle.

[0021] 3. The utility model solves the problem of unstable connection of prefabricated water channels by providing a connecting piece; the close ends of drainage channel 1 and drainage channel 2 are overlapped in the slot of the connecting piece. To ensure the stability of the connection, cement mortar can be used to fill the gap in the connection to ensure the stability of the connection, and the ends of drainage channel 1 and drainage channel 2 just fit into the slot of the connecting piece to ensure stability.

[0022] 4. The utility model solves the problem that the water channel cover plate is easily displaced due to road vibration by providing a cover plate and a limit column; a limit hole is provided on the cover plate, and when the cover plate is placed on the drainage channel, the limit hole is aligned with the limit column, so that the limit column extends out of the limit hole, thereby determining the position of the cover plate, and in the subsequent use process, there is almost no displacement in the absence of external force.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] See also Figure 1-9 As shown, the utility model is a municipal highway drainage channel, comprising a drainage channel 1, a cover plate 2, a drainage channel 3, a connector 5 and a backflow prevention baffle 8, the ends of the drainage channel 1 and the drainage channel 3 close to each other are overlapped in the inner cavity of the connector 5, the upper end surface of the drainage channel 1 is covered with a cover plate 2, and the end of the drainage channel 1 away from the drainage channel 3 is fixed with a sealing plate 101;

[0037] Drainage channel 1 is the starting channel, and subsequent splicing is done by drainage channel 2 3. No components are set in drainage channel 2 3. The difference between cover plate 2 4 and cover plate 1 2 is that: no grille 201 is set on cover plate 2 4; sealing plate 101 is used to block the water inlet end of drainage channel 1;

[0038] An L-shaped primary partition 6 is fixed in the inner cavity of the drainage channel 1, and a secondary partition 7 adapted to its cross-sectional size is also fixed in the inner cavity of the drainage channel 1. The secondary partition 7 is located on the side of the primary partition 6 away from the sealing plate 101. Base blocks 104 are fixed on the two oblique inner walls of the drainage channel 1 on the side of the secondary partition 7 away from the primary partition 6, and a backflow prevention baffle 8 is rotatably connected between the opposite surfaces of the two base blocks 104.

[0039] The primary partition 6 and the secondary partition 7 are used to block and filter the rainwater entering the drainage channel 1 to intercept the impurities in the rainwater. After filtering, the rainwater impacts the backflow prevention baffle 8 to tilt it, and the water flows through the bottom of the baffle 8 and enters the drainage channel 2 3. When there is too much water in the drainage channel 2 3 and backflow occurs, it will impact the backflow prevention baffle 8. At this time, the backflow prevention baffle 8 is limited by the limiting protrusion 105 and is in a vertical state to limit the backflow.

[0040] A grille 201 is fixed in the opening in the cover plate 2; the grille 201 is used to filter rainwater flowing down from the ground and filter out large branches and leaves.

[0041] The bottom surface of the cover plate 2 at one end of the grille 201 is fixed with reinforcement strips 203 distributed at equal intervals; the length of the cover plate 2 is greater than the length of the drainage channel 1, and the width of the cover plate 2 is greater than the maximum width of the drainage channel 1;

[0042] The reinforcing strip 203 can increase the pressure-bearing strength of the cover plate 2 and reduce the damage failure rate. The large size of the cover plate 2 can fully cover the drainage channel 1.

[0043] The two long sides of the cover plate 2 are provided with equally spaced limiting holes 202, and limiting posts 103 matching the number of limiting holes 202 are fixed on both sides of the upper end of the drainage channel 1, and the limiting posts 103 pass upward through the limiting holes 202 vertically corresponding thereto;

[0044] When the cover plate 2 is placed on the drainage channel 1, the limiting holes 202 are aligned with the corresponding limiting columns 103 in a vertical line, thereby ensuring that the cover plate 2 is firmly clamped on the drainage channel 1.

[0045] The outer side of the drainage channel 1 is fixed with reinforcing ribs 102 distributed at equal intervals, and the upper end cover of the drainage channel 2 3 is provided with a cover plate 2 4, and the overall size of the cover plate 2 4 is equal to the overall size of the cover plate 1 2; the structural dimensions of the drainage channel 1 and the drainage channel 2 3 are the same;

[0046] The outer periphery of the drainage channel 1 is reinforced with ribs 102 to increase the structural strength. Since it is a prefabricated component, it needs to be buried in an underground trench.

[0047] Two symmetrical slots 501 are provided in the connecting member 5, and the adjacent ends of the drainage channel 1 1 and the drainage channel 2 3 are respectively overlapped in a slot 501 adjacent thereto;

[0048] The close ends of drainage channel 1 and drainage channel 2 3 are overlapped in the slot 501 of the connector 5, and the ends of drainage channel 1 and drainage channel 2 3 just fit in the slot 501 of the connector 5. To ensure the stability of the connection, cement mortar can be used to fill the gap in the connection to ensure the stability of the connection.

[0049] The long side of the primary partition 6 is provided with through holes 601 distributed in a rectangular array, and the secondary partition 7 is provided with through holes 701 distributed at equal intervals, and the inner diameter of through hole 2 701 is smaller than the inner diameter of through hole 1 601; the design of gradually decreasing inner diameter can achieve filtering processing with increased precision components.

[0050] Furthermore, a limiting protrusion 105 is fixed at the bottom of the drainage channel 1 on one side of the anti-backflow baffle 8 close to the secondary baffle 7; the limiting protrusion 105 can prevent the anti-backflow baffle 8 from approaching the secondary baffle 7. When the water body flows back, it can only maintain a vertical state, and the water body cannot flow to the secondary baffle 7 through the anti-backflow baffle 8.

[0051] The specific working principle of the utility model is as follows: first, the drainage channel 1 and the drainage channel 2 3 are both buried in the underground trench, and the connecting piece 5 is placed between the two. The ends of the drainage channel 1 and the drainage channel 2 3 that are close to each other are overlapped in the card slot 501 of the connecting piece 5. In order to ensure the connection stability, cement mortar can be used to fill the gap at the connection. Then, the cover plate 1 2 is covered on the drainage channel 1, and the limiting holes 202 and the corresponding limiting columns 103 are aligned in the vertical line, so as to ensure that the cover plate 1 2 is firmly connected to the drainage channel 1 1; similarly, the cover plate 2 4 is also covered on the drainage channel 2 3 in the same way, and the end of the drainage channel 2 3 away from the drainage channel 1 1 is laid with the connecting piece 5 and the other drainage channel 2 3, and the laying can be repeated in this way;

[0052] During drainage, drainage channel 1 is the starting channel, and rainwater enters drainage channel 1 through grille 201 on cover plate 12. Grille 201 is used to filter rainwater flowing down from the ground, filter out large branches and leaves, etc., and then enter the inner cavity where primary partition 6 is located, and use through hole 1 601 for secondary filtration and export, and then transport to secondary partition 7, and use through hole 2 701 for tertiary filtration to intercept debris in rainwater, and finally discharge to anti-backflow baffle 8, impact anti-backflow baffle 8, make it tilt, and rainwater passes under it. When too much water accumulates in drainage channel 2 3, there may be surge phenomenon, resulting in backflow, etc. At this time, the water flow will reversely impact anti-backflow baffle 8, and anti-backflow baffle 8 is limited by limiting protrusion 105, and can only be set vertically, so as to ensure that the water flow will not re-enter drainage channel 1 on the side of anti-backflow baffle 8 close to secondary baffle 7.

[0053] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
