Description

Technical Field

[0001] The present application relates to the technical field of road drainage, and in particular to a gutter drainage cover for railways or highways. Background Art

[0002] In the early stages of railway or highway construction, side slope construction begins. Side slopes are defined as slopes with a defined gradient on either side of the roadbed to ensure roadbed stability. After side slope construction is complete, drainage ditches (gutters) are constructed along the slopes. Subsequently, the railway or highway subgrade is constructed at the bottom of the slopes. These drainage ditches collect rainwater from the slopes, reducing erosion of the roadbed.

[0003] However, under the erosion of rainwater, the soil on the slope will partially collapse, and the collapsed soil will enter the drainage ditch, causing the drainage ditch to be blocked. After the drainage ditch is blocked, the water in the drainage ditch is difficult to drain, so that the rainwater in the drainage ditch overflows and flows onto the slope surface, scouring the slope surface, thereby causing new collapse of the soil in the lower part of the drainage ditch, affecting the safe operation of the highway or railway. Summary of the Invention

[0004] In order to solve the problem that small landslides do not block gutters while not affecting the path of water from the slope above the gutter into the gutter, the present application provides a gutter drainage cover for railways or highways.

[0005] The present application provides a railway or highway gutter drainage cover plate adopting the following technical solution:

[0006] A gutter drainage cover for railways or highways comprises a drainage cover, the drainage cover being provided with a plurality of first water leakage holes, the drainage cover being tilted and arranged above the gutter, the height of the drainage cover being closer to the road being lower than the height of the side away from the road; further comprising a support rod, the support rod being vertically arranged on the slope, the drainage cover being fixedly arranged on the support rod; a retaining plate being provided on the support rod along an inclined direction perpendicular to the slope, the bottom of the retaining plate being supported on the slope, the retaining plate being provided with a second water leakage hole, and the drainage cover and the retaining plate enclosing the opening of the gutter.

[0007] Optionally, the drainage cover plate is a rectangular plate, the first leakage holes are arranged in a rectangular array on the drainage cover plate, and adjacent drainage cover plates are connected by steel wire ropes passing through the first leakage holes close to each other on the adjacent drainage cover plates.

[0008] Optionally, a drainage cover plate is fixed by four support rods, and the four support rods are arranged in a rectangular shape. Two of the support rods along the length direction of the gutter are slidably provided with transverse purlins, and the transverse purlins slide along the length direction of the support rods; a plurality of through holes are provided on the support rods, and the plurality of through holes are evenly arranged along the length direction of the support rods, and pins are inserted into the support rods through the through holes, and the transverse purlins are supported on the pins, and a plurality of connecting holes are provided on the transverse purlins, and the drainage cover plate is fixedly connected to the transverse purlins by passing a steel wire rope through the first leakage hole and the connecting hole.

[0009] Optionally, the retaining plate is fixedly connected to the transverse purlin by passing a steel wire rope through the connecting hole and the second leakage hole, and is fixedly connected to the support rod by passing a steel wire rope through the through hole and the second leakage hole on the support rod.

[0010] Optionally, transverse supporting purlins are fixedly arranged between adjacent support rods along the width direction of the gutter.

[0011] Optionally, the drainage cover plate and retaining plate are both steel plates.

[0012] Optionally, when the slopes of adjacent drainage cover plates are inconsistent, a closing plate is provided between the adjacent drainage cover plates, a plurality of third leakage holes are provided on the closing plate, the closing plate is in a vertical direction, and the closing plate is fixedly connected to the adjacent drainage cover plates by means of steel wire ropes passing through the first leakage hole and the third leakage hole, the second leakage hole and the third leakage hole respectively.

[0013] Optionally, the transverse purlin is supported on a receiving surface of the latch with an insert block protruding outwardly, the latch is provided with a slot for the insert block to be inserted, and the length direction of the slot is perpendicular to the axial direction of the through hole.

[0014] Optionally, the connecting steel wire ropes between adjacent drainage cover plates are arranged in a staggered manner.

[0015] Optionally, steel wire ropes are bundled at intersections of adjacent staggered connected steel wire ropes.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. After the drainage cover and retaining plate are installed above the gutter through the support rod, when rainwater washes on the slope and causes the slope to partially collapse, the soil collapses along the slope onto the drainage cover and retaining plate. Under the action of the drainage cover and retaining plate, the soil and rainwater are separated, so that when the slope partially collapses, the soil will not enter the gutter, the gutter will not be blocked, and the rainwater will overflow the gutter and cause rainwater to wash the slope surface, thereby ensuring that the rainwater is discharged outside the range that affects the railway or highway; further, after the soil collapses, part of the soil is blocked by the retaining plate between the retaining plate and the slope protection to reduce the soil coverage The amount of soil on the drainage cover plate is reduced, thereby reducing the degree to which the soil covers the drainage cover plate, thereby ensuring the water-passing efficiency of the drainage cover plate and facilitating the discharge of rainwater; further, the drainage cover plate is arranged at an angle, and the soil collapsed on the drainage cover plate rolls and slides off the drainage cover plate along the drainage cover plate, thereby reducing the degree to which the soil covers the drainage cover plate, thereby ensuring the water-passing efficiency of the drainage cover plate; further, after the soil collapses on the drainage cover plate, part of the soil is removed from the drainage cover plate under the scouring effect of rainwater, thereby ensuring the water-passing effect of the drainage cover plate, thereby ensuring the drainage capacity of the gutter;

[0018] 2. The drain cover can change its inclination angle by adjusting the position of the latch, so that the drain cover can adapt to the slopes with different slopes, so as to facilitate the separation of the soil on the drain cover. Furthermore, by changing the position of the latch, the drain cover can be adapted to slopes with different slopes. Since the specifications of the drain cover are fixed, the drain cover can be easily fitted on gutters of different specifications by adjusting the slope of the drain cover, thereby increasing the applicability of the drain cover.

[0019] 3. The drainage cover and retaining plate are made of punched steel plates and are connected to the transverse purlins and support rods by steel wire ropes, which makes it easy to remove the drainage cover from the transverse purlins and support rods, so as to facilitate the reuse of the drainage cover; and the drainage cover is transported to the site for splicing, which improves the construction efficiency of the drainage cover; adjacent drainage covers are connected by steel wire ropes, which facilitates the installation and removal of the drainage cover to achieve the purpose of reuse.

[0020] 4. The transverse purlin facilitates the fixed installation of the retaining plate and the drainage cover. At the same time, it connects the two adjacent support rods into a whole, thereby improving the bearing capacity of the support rods. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present application is further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 2 and Figure 3 , further comprising a support rod 5, which is vertically arranged on the slope 1. The support rod 5 is a steel pipe. In the embodiment of the present application, the support rod 5 is fixed to the slope 1 by opening a mounting hole on the slope protection, inserting the support rod 5 into the mounting hole, and pouring concrete. The drainage cover plate 2 is fixed on the support rod 5;

[0033] Reference Figure 2 and Figure 3 Furthermore, a retaining plate 6 is provided on the support rod 5 along the inclined direction perpendicular to the slope 1. The bottom of the retaining plate 6 is supported on the slope 1. A second drainage hole 7 is provided on the retaining plate 6. A plurality of second drainage holes 7 are provided and arranged in a rectangular row on the retaining plate 6. The drainage cover plate 2 and the retaining plate 6 enclose the opening of the gutter 4.

[0034] Reference Figure 2 and Figure 3 The drainage cover plate 2 and the retaining plate 6 are both made of steel plates, and the first leakage hole 3 and the second leakage hole 7 are formed by openings in the steel plates.

[0035] When installing the drainage cover 2, the support rod 5 is first cast on the slope 1, and then the retaining plate 6 and the drainage cover 2 are fixed on the support rod 5. The retaining plate 6 and the drainage cover 2 enclose the opening of the gutter 4, so that the opening of the gutter 4 is located in the space enclosed by the retaining plate 6 and the drainage cover 2 to block the soil entering the gutter 4, thereby reducing the possibility of local collapse of the slope 1 causing blockage of the gutter 4.

[0036] Reference Figure 2 and Figure 4 In the embodiment of the present application, in order to facilitate the transportation, installation and reuse of the drainage cover plate 2, the drainage cover plate 2 is a rectangular plate, and the first leakage holes 3 are arranged in a rectangular array on the drainage cover plate 2. The adjacent drainage cover plates 2 are connected by steel wire ropes 8 passing through the first leakage holes 3 close to each other on the adjacent drainage cover plates 2; when the adjacent drainage cover plates 2 are connected, the steel wire ropes 8 are passed through the first leakage holes 3 on the drainage cover plates 2, and the adjacent drainage cover plates 2 are connected as a whole by tying them with the steel wire ropes 8; in the embodiment of the present application, the adjacent tying steel wire ropes 8 are parallel to each other to reduce the use of the steel wire ropes 8 and reduce the cost investment.

[0037] Reference Figure 2 and Figure 3 In the embodiment of the present application, a drainage cover plate 2 is fixed by four support rods 5, and the four support rods 5 are arranged in a rectangular shape. Two support rods 5 along the length direction of the gutter 4 are slidably provided with transverse purlins 9. The transverse purlins 9 are long and rectangular in cross section. The transverse purlins 9 slide along the length direction of the support rods 5.

[0038] Reference Figure 2 and Figure 3 A plurality of through holes 10 are provided on the support rod 5, and the distance between adjacent through holes 10 is 5-15 cm. In the present application, the distance between the through holes 10 is 10 cm. The plurality of through holes 10 are evenly arranged along the length direction of the support rod 5. A latch 11 is inserted through the through hole 10 on the support rod 5. The cross section of the latch 11 is rectangular. The transverse purlin 9 is supported on the latch 11. A plurality of connecting holes 12 are provided on the transverse purlin 9. The connecting holes 12 are evenly arranged along the length direction of the transverse purlin 9. The drainage cover plate 2 is fixedly connected to the transverse purlin 9 by passing the steel wire rope 8 through the first leakage hole 3 and the connecting hole 12.

[0039] When the drainage cover plate 2 is fixed on the support rod 5, the transverse purlin 9 is first placed on the adjacent support rod 5, and then the transverse purlin 9 is fixed to the support rod 5 using the pin 11, and then the drainage cover plate 2 is placed on the transverse purlin 9. During this process, the position of the pin 11 is adjusted to change the inclination angle of the drainage cover plate 2 so that the drainage cover plate 2 adapts to the slope of the slope 1; then the steel wire rope 8 is used to pass through the connecting hole 12 and the first leakage hole 3 to tie the drainage cover plate 2 to the transverse purlin 9. The operation is simple and convenient; and it is convenient to remove the drainage cover plate 2 from the transverse purlin 9 after the concrete of the slope 1 is sprayed in the later stage for reuse.

[0040] Reference Figure 2 and Figure 3 In the embodiment of the present application, the retaining plate 6 is located between the two support rods 5 along the length direction of the gutter 4, and the two ends of the retaining plate 6 are respectively abutted against the side walls of the corresponding support rods 5. The retaining plate 6 is fixedly connected to the transverse purlin 9 by the steel wire 8 passing through the connecting hole 12 and the second leakage hole 7, and is fixedly connected to the support rod 5 by the steel wire 8 passing through the through hole 10 on the support rod 5 and the second leakage hole 7. When the retaining plate 6 is installed, the retaining plate 6 is placed and moved below the transverse purlin 9, and the retaining plate 6 is supported on the slope. 1, then pass the steel wire rope 8 through the connecting hole 12 on the transverse purlin 9 and the second leakage hole 7 on the retaining plate 6, and tie the upper part of the retaining plate 6 to the transverse purlin 9; after the upper part of the retaining plate 6 is fixed to the transverse purlin 9, adjust the position of the retaining plate 6 so that the two ends of the retaining plate 6 are respectively in contact with the support rod 5, and then use the steel wire rope 8 to pass through the through hole 10 and the second leakage hole 7 to tie the retaining plate 6 to the support rod 5, and then fix the retaining plate 6 to the transverse purlin 9 and the support rod 5. The operation is simple and convenient.

[0041] Reference Figure 2 and Figure 3 When the span of the gutter 4 is large, the support rod 5 is subjected to a large force, which can easily cause the support rod 5 to bend. In order to improve the stability of the support rod 5, a transverse supporting purlin 13 is fixedly arranged along the width direction of the gutter 4 and between adjacent support rods 5. The transverse supporting purlin 13 is fixed to the support rod 5 by welding or other means, and the support rod 5 is arranged parallel to the width direction of the gutter 4; under the action of the support rod 5, the overall stiffness of the support rod 5, the retaining plate 6 and the drainage cover plate 2 is improved, thereby improving the bearing capacity of the drainage cover plate 2 and the retaining plate 6, and reducing the possibility of collapse of the drainage cover plate 2.

[0042] Reference Figure 2 and Figure 3In the embodiment of the present application, in order to reduce the possibility of the latch 11 accidentally falling off the support rod 5, the transverse purlin 9 is supported on the receiving surface of the latch 11 with an insert block protruding outward, and the latch 11 is provided with a slot for the insert block to be inserted, and the length direction of the slot is perpendicular to the axial direction of the through hole 10; after the latch 11 is inserted into the support rod 5, the transverse purlin 9 is placed on the latch 11, and the insert block is moved into the slot. Under the action of the insert block and the slot, the latch 11 is relatively fixedly installed on the transverse purlin 9, so that the latch 11 and the transverse purlin 9 become a whole, thereby reducing the possibility of the latch 11 falling off from the support rod 5.

[0043] The implementation principle of Example 1 is:

[0044] After the construction of the gutter 4 is completed, the support rods 5 are cast on both sides of the gutter 4. Then, the pins 11 are inserted into the corresponding through holes 10 according to the slope of the slope 1. Then, the transverse purlin 9 is sleeved on the support rod 5, and then the transverse purlin 9 is slid onto the pins 11. During this process, the plugs on the transverse purlin 9 are inserted into the slots; then, the drainage cover 2 is received on the transverse purlin 9, and the drainage cover 2 is fixed to the transverse purlin 9 using the wire rope 8; then, the retaining plate 6 is installed under the transverse purlin 9, and the retaining plate 6 is tied to the transverse purlin 9 and the support rod 5 using the wire rope 8 to complete the installation of the drainage cover 2;

[0045] When rainwater washes on the slope 1 and causes the gutter 4 to partially collapse, the soil collapses along the slope 1 onto the drainage cover 2 and the retaining plate 6. Under the action of the drainage cover 2 and the retaining plate 6, the soil and rainwater are separated, so that when the slope 1 partially collapses, the soil will not enter the gutter 4, the gutter 4 will not be blocked, and the rainwater will not overflow the gutter 4 and cause the rainwater to wash the slope surface, thereby ensuring that the rainwater is discharged outside the range that affects the railway or highway.

[0046] Example 2

[0047] The difference between Example 2 and Example 1 is that, Figure 5 The connecting steel wire ropes 8 between adjacent drainage cover plates 2 are arranged in a staggered manner. Furthermore, adjacent connecting steel wire ropes 8 are arranged in an "X" shape. When adjacent drainage cover plates 2 are connected by steel wire ropes 8, the steel wire ropes 8 are arranged in a staggered manner, so that the gaps between adjacent drainage cover plates 2 and between adjacent steel wire ropes 8 are reduced, and the collapsed soil is carried on the steel wire ropes 8 to reduce the amount of soil entering the gutter 4, thereby reducing the possibility of clogging of the gutter 4.

[0048] Reference Figure 5 Furthermore, the intersections of the adjacent staggered connected steel wire ropes 8 are tied with steel wire ropes 8, and the steel wire ropes 8 tied at the intersections are arranged in a direction parallel to the width of the gutter 4, thereby reducing the gaps between the staggered steel wire ropes 8 and further reducing the possibility of soil entering the gutter 4.

[0049] The implementation principle of Example 2 is:

[0050] When adjacent drainage cover plates 2 are connected by steel wire ropes 8, the steel wire ropes 8 are arranged in an staggered manner, so that the gaps between adjacent drainage cover plates 2 and between adjacent steel wire ropes 8 are reduced, and the collapsed soil is carried on the steel wire ropes 8 to reduce the amount of soil entering the gutter 4, thereby reducing the possibility of gutter 4 being blocked.

[0051] Example 3

[0052] The difference between Example 3 and Example 1 is that, referring to Figure 6 and Figure 7 When the slopes of adjacent drainage covers 2 are inconsistent, a closing plate 14 is provided between the adjacent drainage covers 2. The closing plate 14 is a rectangular plate. The two sides of the closing plate 14 are respectively in contact with the drainage covers 2 on both sides. A plurality of third leakage holes 15 are provided on the closing plate 14. The closing plate 14 is in a vertical direction. The closing plate 14 is fixedly connected to the adjacent drainage covers 2 through the first leakage hole 3 and the third leakage hole 15, the second leakage hole 7 and the third leakage hole 15 by the steel wire rope 8; when the slope of the slope 1 suddenly changes, the drainage covers 2 are built according to the slope of the slope 1, resulting in a gap between the adjacent drainage covers 2, causing the soil to enter the gutter 4 through this gap. Under the action of the closing plate 14, the gap between the adjacent drainage covers 2 is closed, and the soil is blocked to reduce the soil entering the gutter 4.

[0053] The implementation principle of Example 3 is:

[0054] During the installation of the drainage cover 2, if the slope of the drainage cover 2 is inconsistent, move the closing plate 14 between the two drainage cover plates 2, and then use the wire rope 8 to tie the machine closing plate 14 to the drainage cover 2 to complete the installation of the closing plate 14. The operation is simple and convenient.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
