Description

Technical Field

[0001] This utility model relates to the field of slope protection and drainage technology, specifically to a steel corrugated pipe rapid flow channel for loose gravel slopes. Background Technology

[0002] In the construction of infrastructure projects such as mountain highways, railways, and water conservancy projects, loose gravelly soil slopes are frequently encountered. Due to their loose soil structure and weak interparticle cohesion, these slopes are highly susceptible to soil erosion and slope collapse under the influence of natural factors such as rainwater runoff, posing a serious threat to the stability and safety of engineering facilities. Rapid flow channels, as a common slope drainage system, play a crucial role in guiding slope water flow and reducing erosion of the slope.

[0003] In related technologies, the commonly used rapid flow channels are mostly constructed with concrete. However, concrete construction often requires steps such as surface preparation and formwork erection, which are not easy to carry out on loose gravel soil, thus making construction on loose gravel soil slopes more difficult. Utility Model Content

[0004] The problem solved by this utility model is to provide a rapid flow channel structure that is easier to construct on loose gravelly soil slopes.

[0005] To solve the above problems, this utility model provides a corrugated steel pipe rapid flow channel for loose gravel slopes.

[0006] This utility model provides a corrugated steel pipe rapid flow channel for loose gravel slopes, including a corrugated steel pipe body and an anchoring structure. The anchoring structure is used to be installed in the ditch of the slope, and the corrugated steel pipe body is used to be placed in the ditch and connected to the anchoring structure, and the corrugated steel pipe body extends along the length direction of the ditch.

[0007] Optionally, the outer diameter of the corrugated steel pipe body is greater than the depth of the groove.

[0008] Optionally, the corrugated steel pipe body includes a plurality of corrugated steel pipes arranged sequentially along the extension direction of the corrugated steel pipe body, and adjacent corrugated steel pipes are detachably connected.

[0009] Optionally, flange connecting plates are welded to both ends of the corrugated steel pipe, and the flange connecting plates of two adjacent corrugated steel pipes are connected by fastening bolts, and a rubber sealing ring is sandwiched between the two flange connecting plates.

[0010] Optionally, the anchoring structure includes an anchor rod, one end of which is inserted into the slope through the bottom surface of the trench, and the other end is exposed in the trench. The corrugated steel pipe body is connected to the exposed end of the anchor rod.

[0011] Optionally, a connecting plate with a through hole is welded to the main body of the corrugated steel pipe. The exposed end of the anchor rod is provided with an external thread. The exposed end of the anchor rod passes through the through hole of the connecting plate. A fixing nut is connected to the external thread. The fixing nut is located on the side of the connecting plate opposite to the insertion end of the anchor rod, and is used to fix the connecting plate to the anchor rod.

[0012] Optionally, a reinforcing rib is connected between the outer wall of the corrugated steel pipe body and the connecting plate.

[0013] Optionally, it also includes an energy dissipation buffer pool communicating with the lower end of the corrugated steel pipe body. The energy dissipation buffer pool has a first sidewall and a second sidewall that are arranged opposite to each other along the extension direction of the corrugated steel pipe body. The first sidewall is provided with an inlet for the lower end of the corrugated steel pipe body to be inserted, and the second sidewall is provided with an outlet.

[0014] Optionally, it also includes a slope protection layer, which includes a geogrid for laying around the trench and vegetation laid on the geogrid.

[0015] Optionally, the corrugated steel pipe body is made of high-strength galvanized steel.

[0016] The beneficial effects of this utility model of a corrugated steel pipe rapid flow channel for loose gravel slopes are as follows: Because the corrugated steel pipe body is placed in the channel and extends along its length, allowing water to flow quickly downwards and be discharged, thus achieving slope drainage, the corrugated steel pipe body fulfills the function of a rapid flow channel. Compared to traditional concrete rapid flow channels, the corrugated steel pipe body eliminates the need for surface preparation and formwork erection, making it easier to install on loose gravel slopes. This reduces the need for extensive construction work on loose gravel slopes. The construction is challenging; furthermore, the corrugated structure of the steel corrugated pipe itself can buffer the water flow to dissipate its energy and reduce scouring damage to the slope; in addition, the corrugated structure of the steel corrugated pipe itself can increase the overall rigidity and load-bearing capacity of the steel corrugated pipe to adapt to the uneven settlement and lateral pressure that may occur on loose gravel slopes, thus enabling more reliable slope drainage; furthermore, since the steel corrugated pipe body is connected to the anchoring structure, the steel corrugated pipe body can be firmly fixed to the slope using the anchoring structure to resist the impact of water flow.

[0030] This invention provides a corrugated steel pipe rapid flow channel for loose gravel slopes, which is easier to construct on loose gravel slopes. Detailed description follows with specific embodiments.

[0031] like Figure 1 and Figure 4 As shown in the figure, the present invention provides a corrugated steel pipe chutes for loose gravel slopes, including a corrugated steel pipe body 1 and an anchoring structure 2. The anchoring structure 2 is used to be installed in the ditch 31 of the slope 3. The corrugated steel pipe body 1 is used to be placed in the ditch 31 and connected to the anchoring structure 2, and the corrugated steel pipe body 1 extends along the length direction of the ditch 31.

[0032] It should be noted that the trench 31 is a groove structure excavated on the slope 3. The trench 31 extends along the inclination direction of the slope 3, and its upper end is connected to the water ditch at the top of the slope 3. It can be understood that when the corrugated steel pipe body 1 is placed in the trench 31 and extends along the length of the trench 31, that is, the entire corrugated steel pipe body 1 is arranged along the trench 31, the water accumulated in the ditch can flow through the corrugated steel pipe body 1 and be quickly discharged downwards to realize slope drainage and meet the function of the rapid flow channel.

[0033] In this embodiment, since the corrugated steel pipe body 1 is placed in the trench 31 and extends along the length of the trench 31, that is, the corrugated steel pipe body 1 is arranged along the trench 31, the accumulated water can flow through the corrugated steel pipe body 1 and be quickly discharged downwards to achieve slope drainage. In other words, the corrugated steel pipe body 1 can fulfill the function of a rapid flow channel. Compared with traditional concrete rapid flow channels, the corrugated steel pipe body 1 does not require surface preparation or formwork erection, and can be easily installed on loose gravel soil, thereby reducing the difficulty of construction on loose gravel soil slopes 3. Furthermore, the steel... The corrugated structure of the corrugated pipe body 1 can buffer the water flow to dissipate its energy and reduce scouring damage to the slope. Furthermore, the corrugated structure of the corrugated pipe body 1 can increase the overall rigidity and load-bearing capacity of the corrugated pipe 11 to adapt to the uneven settlement and lateral pressure that may occur on the loose gravel slope 3, thereby enabling more reliable slope drainage. Moreover, since the corrugated pipe body 1 is connected to the anchoring structure 2, the corrugated pipe body 1 can be firmly fixed to the slope 3 using the anchoring structure 2 to resist the impact of water flow.

[0034] Optionally, the corrugated steel pipe body 1 is made of high-strength galvanized steel.

[0035] Specifically, the corrugated shape of the steel corrugated pipe body 1 can be a sine wave or a cosine wave, without limitation. In addition, in some embodiments, the wave height of the corrugated shape of the steel corrugated pipe body 1 can be 57 mm, the wavelength can be 230 mm, and the thickness can be 5 mm.

[0036] In this optional embodiment, by selecting high-strength galvanized steel as the material of the corrugated steel body 1, the strength and corrosion resistance of the corrugated steel body 1 can be improved, thereby helping to ensure the reliability of this rapid flow channel.

[0037] Optionally, the outer diameter of the corrugated steel pipe body 1 is greater than the depth of the groove 31.

[0038] The outer diameter of the corrugated steel pipe body 1 can be selected within the range of 40 to 60 centimeters, and the specific diameter can be determined according to the catchment area of ​​the slope 3 and the design flow rate. In addition, it is preferable that the outer diameter of the corrugated steel pipe body 1 is twice the depth of the trench 31, so that the corrugated steel pipe body 1 is exactly 1 / 2 contained in the trench 31.

[0039] In this optional embodiment, by making the outer diameter of the corrugated steel pipe body 1 larger than the depth of the trench 31, the corrugated steel pipe body 1 can partially protrude from the trench 31. Because the corrugated steel pipe body 1 protrudes from the trench 31, after the slope protection layer 7 is subsequently installed around the trench 31, the surface of the slope protection layer 7 and the surface of the corrugated steel pipe body 1 will not have too much unevenness, thereby improving the overall aesthetics of the slope 3.

[0040] Optionally, such as Figure 2 As shown, the corrugated steel pipe body 1 includes a plurality of corrugated steel pipes 11 arranged sequentially along the extension direction of the corrugated steel pipe body 1, and adjacent two corrugated steel pipes 11 are detachably connected.

[0041] In this optional embodiment, if the corrugated steel pipe body 1 is integrally formed, it will be difficult to transport to the slope 3 for installation due to its large weight, thereby increasing the difficulty of construction. However, this solution makes the two adjacent corrugated steel pipes 11 detachably connected, so that the entire corrugated steel pipe body 1 can be disassembled into multiple parts for transportation and then reassembled at the slope 3. This can greatly reduce the construction difficulty of the corrugated steel pipe body 1.

[0042] Optionally, such as Figure 3 As shown, flange connecting plates 111 are welded to both ends of the corrugated steel pipe 11. The flange connecting plates 111 of two adjacent corrugated steel pipes 11 are connected by fastening bolts 4, and a rubber sealing ring 5 is sandwiched between the two flange connecting plates 111.

[0043] It should be noted that there can be multiple fastening bolts 4 on two adjacent flange connecting plates 111, and the multiple fastening bolts 4 are evenly spaced along the periphery of the flange connecting plate 111 to ensure the connection strength of the two flange connecting plates 111.

[0044] In this optional embodiment, the flange connecting plates 111 of two adjacent steel corrugated pipes 11 are connected by fastening bolts 4, which can realize the detachable connection between the two adjacent steel corrugated pipes 11. The structure is simple and easy to install. In addition, by clamping a rubber sealing ring 5 between the two flange connecting plates 111, it is beneficial to ensure the sealing of the connection between the two steel corrugated pipes 11 and prevent water leakage.

[0045] Optionally, such as Figure 4 As shown, the anchoring structure 2 includes an anchor rod 21. One end of the anchor rod 21 is inserted into the slope 3 through the bottom surface of the trench 31, and the other end is exposed in the trench 31. The corrugated steel pipe body 1 is connected to the exposed end of the anchor rod 21.

[0046] Specifically, the length of the anchor rod 21 can be 6 to 9 meters to ensure sufficient pre-embedding depth. In addition, the diameter of the anchor rod 21 can be 32 millimeters to ensure sufficient structural strength.

[0047] In this optional embodiment, since one end of the anchor rod 21 is inserted into the slope 3 through the bottom surface of the trench 31 and the other end is exposed in the trench 31, and the corrugated steel pipe body 1 is connected to the exposed end of the anchor rod 21, the corrugated steel pipe body 1 can be firmly fixed to the slope 3 by the anchor rod 21 to prevent displacement when water flow impacts and the soil of the slope 3 deforms.

[0048] Optionally, such as Figure 4 and Figure 5 As shown, a connecting plate 112 with a through hole 1121 is welded onto the main body 1 of the corrugated steel pipe. The exposed end of the anchor rod 21 is provided with an external thread 211. The exposed end of the anchor rod 21 passes through the through hole 1121 of the connecting plate 112. A fixing nut 212 is connected to the external thread 211. The fixing nut 212 is located on the side of the connecting plate 112 away from the insertion end of the anchor rod 21, and is used to fix the connecting plate 112 onto the anchor rod 21.

[0049] It should be noted that the exposed end of the anchor rod 21 is the end of the anchor rod 21 that is exposed in the trench 31, and the inserted end of the anchor rod 21 is the end of the anchor rod 21 that is inserted into the slope 3. Specifically, one end of the connecting plate 112 can be welded to the bottom of the corrugated steel pipe body 1 near the anchor rod 21, while the other end is exposed on one side (left or right) of the corrugated steel pipe body 1. A through hole 1121 is provided at the exposed end of the connecting plate 112, so that the through hole 1121 can be exposed on one side of the corrugated steel pipe body 1, thereby facilitating easier and faster insertion with the anchor rod 21.

[0050] In this optional embodiment, the above-mentioned arrangement allows the fixing nut 212 to be unscrewed from the exposed end of the anchor rod 21. When the fixing nut 212 is removed, the connecting plate 112 is no longer limited by the fixing nut 212 and can be removed from the exposed end of the anchor rod 21. This enables the connecting plate 112 to be detachably installed on the anchor rod 21, thereby indirectly realizing the detachable connection between the corrugated pipe body 1 and the anchor rod 21, facilitating the disassembly and replacement of the corrugated pipe body 1.

[0051] Optionally, such as Figure 6 As shown, a reinforcing rib 113 is connected between the outer wall of the corrugated steel pipe body 1 and the connecting plate 112.

[0052] Specifically, one end of the reinforcing rib 113 can be connected to the outer wall of the corrugated steel pipe body 1, while the other end can be connected to the middle of the connecting plate 112 along the length direction to improve the reinforcing effect.

[0053] In this optional embodiment, by providing reinforcing ribs 113 between the outer wall of the corrugated steel pipe body 1 and the connecting plate 112, the connection strength between the connecting plate 112 and the corrugated steel pipe body 1 is improved.

[0054] Optionally, such as Figure 1 and Figure 7 As shown, the corrugated steel pipe rapid flow channel for loose gravel slope also includes an energy dissipation buffer pool 6 connected to the lower end of the corrugated steel pipe body 1. The energy dissipation buffer pool 6 has a first side wall 61 and a second side wall 62 arranged opposite to each other along the extension direction of the corrugated steel pipe body 1. The first side wall 61 is provided with an inlet 611 for the lower end of the corrugated steel pipe body 1 to be inserted, and the second side wall 62 is provided with an outlet 621. An energy dissipation block 63 is provided inside the energy dissipation buffer pool 6.

[0055] Specifically, multiple energy dissipation blocks 63 can be set, and the multiple energy dissipation blocks 63 are arranged in a multi-layered staggered manner, which can improve the energy dissipation and buffering effect on water flow. In addition, the shape of the energy dissipation block 63 can be a triangular pyramid or a square pyramid, and there is no restriction here.

[0056] In this optional embodiment, after the water flows through the corrugated steel pipe body 1, it can enter the interior of the energy dissipation buffer pool 6 through the inlet 611, and then collide with the energy dissipation block 63 and undergo turbulent motion in the pool, which can greatly consume energy and thus reduce the scouring and damage to the downstream.

[0057] Optionally, such as Figure 1 As shown, the corrugated steel pipe chutes for loose gravel slopes also include a slope protection layer 7, which includes a geogrid 71 for laying around the ditch 31 and vegetation 72 laid on the geogrid 71.

[0058] In this optional embodiment, the root system of vegetation 72 can be intertwined with geogrid 71 to form a composite protection system, which can prevent slope gravel from rolling into the rapid flow channel and also play the role of greening the slope 3 and reducing soil erosion.

[0059] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
