Description

Technical Field

[0001] This invention relates to the field of urban road construction technology, specifically a slope protection device for urban road construction. Background Technology

[0002] Slope engineering, a construction term, refers to the modification of natural and artificial slopes to meet engineering needs. Based on the time difference of the slope's impact on the project, it can be divided into permanent slopes and temporary slopes. Based on the relationship between the slope and the project, it can be divided into building foundation slopes, adjacent slopes of buildings, and extended slopes with less impact on buildings.

[0003] Patent CN119266257B discloses a slope protection device for urban road traffic engineering construction. Through a slope protection mechanism and auxiliary mechanisms, it achieves graded blocking and impact buffering of stones of different sizes, effectively alleviating the problem of fence breakage and bending due to instantaneous impact. However, the aforementioned slope protection device cannot intercept fine gravel rolling down the gaps at the bottom of the fence, causing fine gravel to wash into the road surface, making it difficult to clean and potentially causing vehicles to skid.

[0004] Based on this, a slope protection device for urban road construction is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of this invention is to provide a slope protection device for urban road construction to solve the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A slope protection device for urban road construction includes a slope protection device body, which is set between the bottom of the slope and the road surface. The bottom of the slope has a first slope, and a second slope is connected to one side of the first slope. A rock-blocking channel is provided on one side of the second slope. The slope protection device body includes several support columns installed at the connection line between the first slope and the second slope. A rock-blocking component is rotatably installed on the lower part of the support column. The rock-blocking component includes a shaft rotatably installed on the support column. A baffle is fixed to the lower part of the shaft. Torsion springs are provided at both ends of the shaft. The torsion springs make the lower end of the baffle fit against the second slope in the initial state. An arc-shaped buffer plate is fixed to the side of the shaft near the slope. The upper part of the arc-shaped buffer plate is divided into multiple water collection chambers by multiple partitions.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions: In one alternative: a water-draining groove is provided on one side of the arc-shaped buffer plate, and a flared opening is provided at one end of the water-draining groove near the inner side of the arc-shaped buffer plate.

[0008] In one alternative: the lower end of the arc-shaped buffer plate is fixed with a pad, and the pad is provided with a material guiding slope.

[0009] In one alternative: the lower end of the support column is provided with a mounting base, and a grid panel is fixedly connected between the support columns, with the grid panel positioned above the shaft.

[0010] In one alternative: a semi-circular rain guide is provided at the top of the support column, with one side of the rain guide located above the water collection cavity and the other side of the rain guide located above the second slope.

[0011] In one alternative: the first slope and the second slope are provided with foundations for installing support columns at equal intervals along the length direction, and the rock-blocking channel has several slots on the side near the road surface that correspond to the positions of the foundations.

[0012] In one alternative: the support column is provided with a gas spring rod on the side near the rock-blocking groove, the upper end of the gas spring rod is hinged to the support column, and the lower end of the gas spring rod is hinged and installed in the groove.

[0013] In one alternative: the pad is made of elastic rubber so that the bottom surface of the pad can fit against the slope, the material guiding slope extends downward from the middle of the arc-shaped buffer plate to both sides to form the material guiding direction indicated by the arrow, and there is a material drop gap between the two ends of the arc-shaped buffer plate and the foundation.

[0014] In one alternative embodiment: the arc-shaped buffer plate is provided with an impact-resistant component at the end away from the shaft. The impact-resistant component includes an arc-shaped baffle. An elastic rubber pad is provided at the lower end of the arc-shaped baffle. Several connecting rods are fixed at the lower end of the arc-shaped baffle. The lower ends of the connecting rods slide through the elastic rubber pad and the arc-shaped buffer plate. The arc-shaped buffer plate is provided with mounting holes for installing the connecting rods. A limit block is fixed at the lower end of the connecting rod.

[0015] In one alternative: the water collection chamber is provided with a filter assembly, the filter assembly including a rotating shaft rotatably mounted on the end of the partition near the shaft and a positioning rod arranged parallel to the rotating shaft, a rigid filter screen is fixed between the positioning rod and the rotating shaft, and the end of the partition away from the shaft is provided with a groove that matches the positioning rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention achieves the technical effect of effectively intercepting fine sand and gravel rolling down the gap at the bottom of the guardrail by setting a rotating rock-blocking component at the connection line between the first slope and the second slope, and using the pre-tension force of the torsion spring to make the lower end of the baffle fit with the second slope to form a dynamic sealing structure. This solves the technical problem that existing slope protection devices cannot intercept fine sand and gravel, causing them to wash into the road surface, making them inconvenient to clean, and potentially causing vehicles to slip.

[0017] 2. This invention uses an arc-shaped buffer plate installed on the side of the shaft near the slope to intercept and buffer larger stones. The upper part of the arc-shaped buffer plate is divided into multiple water collection chambers by a partition. When the water collection chambers are filled with a certain amount of water, the arc-shaped buffer plate will rotate downwards, causing the baffle to detach from the second slope. This allows the sand and gravel accumulated on the second slope to fall into the rock-blocking trough. After the arc-shaped buffer plate rotates downwards, the water in the water collection chambers will be discharged from the drainage trough, washing the sand and gravel on the first and second slopes, thereby achieving automatic cleaning of the sand and gravel.

[0018] 3. The present invention provides an elastic rubber pad with a guide slope at the lower end of the arc-shaped buffer plate. When the arc-shaped buffer plate intercepts a large stone, the arc-shaped buffer plate rotates downward under the pressure of the stone, so that the elastic rubber pad fits against the slope. At this time, the fine sand and gravel rolling down the slope will roll into the rock-blocking trough along the guide slope on the pad, thereby avoiding the accumulation of sand and gravel.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0031] In one embodiment, such as Figures 1-4 As shown, a slope protection device for urban road construction includes a slope protection device body 300, which is positioned between the bottom of a slope 200 and the road surface 100. The bottom of the slope 200 has a first slope 201, and a second slope 202 is connected to one side of the first slope 201. A rockfall barrier 203 is provided on one side of the second slope 202. The slope protection device body 300 includes several support columns 301 installed at the connection line between the first slope 201 and the second slope 202. A rockfall barrier assembly 400 is rotatably mounted on the lower part of each support column 301. The rockfall barrier assembly 400 includes... The shaft 401 is rotatably mounted on the support column 301. A baffle 402 is fixed at the lower part of the shaft 401. Torsion springs are provided at both ends of the shaft 401. The torsion springs make the lower end of the baffle 402 fit against the second slope 202 in the initial state. An arc-shaped buffer plate 403 is fixed on the side of the shaft 401 near the slope 200. The upper end of the arc-shaped buffer plate 403 is divided into multiple water collection chambers 405 by multiple partitions 404. A water leakage groove 406 is opened on one side of the arc-shaped buffer plate 403. A flared mouth 407 is provided at one end of the water leakage groove 406 near the inner side of the arc-shaped buffer plate 403.

[0032] In the initial state, the baffle 402 remains in contact with the second slope 202 under the action of the torsion spring, intercepting the fine sand and gravel rolling off the slope 200. During the process, rainwater is collected through the water collection chamber 405. When a certain amount of rainwater is collected in the water collection chamber 405, the arc-shaped buffer plate 403 rotates downward under the action of gravity, causing the baffle 402 to detach from the second slope 202. This allows the sand and gravel accumulated on the second slope 202 to fall into the rock-blocking trough 203. When the arc-shaped buffer plate 403 rotates downward to a certain position, the water in the water collection chamber 405 will be discharged from the drain trough 406, washing the sand and gravel on the first and second slopes, thus achieving automatic cleaning of the sand and gravel. Then, under the action of the torsion spring, the arc-shaped buffer plate 403 will rotate upward to return to the initial position, and the baffle 402 will also return to the state of contact with the second slope 202, intercepting the fine sand and gravel again.

[0033] In one embodiment, such as Figure 2 and Figure 3 As shown, the lower end of the support column 301 is provided with a mounting base 302, and a grid panel 303 is fixedly connected between the support columns 301. The grid panel 303 is set above the shaft 401. The first slope 201 and the second slope 202 are provided with foundations 204 for installing the support columns 301 at equal intervals along the length direction. The rock catch trough 203 has several slots 205 corresponding to the positions of the foundations 204 on the side near the road surface 100. The support column 301 is provided with a gas spring rod 500 on the side near the rock catch trough 203. The upper end of the gas spring rod 500 is hinged to the support column 301, and the lower end of the gas spring rod 500 is hinged and installed in the slot 205. The buffering effect of the gas spring rod 500 can improve the impact resistance of the support column 301 against larger stones.

[0034] In one embodiment, such as Figures 4-7 As shown, a pad 408 is fixed to the lower end of the arc-shaped buffer plate 403. The pad 408 has a material guiding ramp 409. The pad 408 is made of elastic rubber, allowing its bottom surface to fit against the slope 200. The material guiding ramp 409 extends downwards and outwards from the middle of the arc-shaped buffer plate 403 to form the material guiding direction indicated by arrow A. A material drop gap is provided between the two ends of the arc-shaped buffer plate 403 and the foundation 204. When larger stones roll down the slope 200, they will first contact the arc-shaped buffer plate 403, and... The curved buffer plate 403 is rotated downwards until the pad 408 contacts the slope 200. The rotation of the curved buffer plate 403 and the elastic deformation of the pad 408 achieve the buffering effect on the stones. After the stones fall on the curved buffer plate 403, the pad 408 will always be in contact with the slope 200 until personnel clean it up. During this process, smaller sand and gravel rolling off the slope will fall into the rock-blocking trough 203 from the material drop gaps on both sides of the curved buffer plate 403 along the material guide slope 409 in the direction of arrow A, thus avoiding accumulation.

[0035] In one embodiment, such as Figure 3 As shown, a semi-circular rain guide 304 is provided at the top of the support column 301. One side of the rain guide 304 is located above the water collection chamber 405, and the other side of the rain guide 304 is located above the second slope 202. The rain guide 304 can improve the water collection efficiency of the water collection chamber 405, thereby increasing the frequency of cleaning up the accumulated sand and gravel.

[0036] The above embodiments disclose a slope protection device for urban road construction. Its working principle is as follows: In a dry, rainless state, the baffle 402 remains in contact with the second slope 202 under the action of a torsion spring, forming a physical barrier to intercept fine sand and gravel rolling off the slope 200 and prevent them from intruding into the road surface 100. During rainfall, the water collection cavity 405 on the arc-shaped buffer plate 403 collects rainwater. When the water volume reaches a set threshold, the gravitational torque overcomes the torsion spring preload, driving the shaft 401 to rotate, causing the baffle 402 to detach from the second slope 202, and the accumulated sand and gravel fall into the rock-blocking trough 203 under gravity. Simultaneously, the arc-shaped buffer plate 403 rotates downward to a specific angle, and the water collection cavity 405... Water in section 5 is discharged through the drainage channel 406 to wash the surfaces of the first slope 201 and the second slope 202, achieving automatic cleaning of sand and gravel. After drainage, the gravitational torque decreases, and the torsion spring drives the arc-shaped buffer plate 403 to rotate upward and reset. The baffle 402 re-fits the second slope 202, restoring the interception function. When larger stones roll off the slope 200 and impact the arc-shaped buffer plate 403, the plate rotates downward and absorbs the impact energy through the deformation of the elastic rubber pad 408. During the stone retention period, the pad 408 remains in contact with the slope 200, while subsequent fine sand and gravel slide to both sides along the guide slope 409 and enter the rock-blocking channel 203 through the material drop gap, avoiding secondary accumulation. Example 2

[0037] Unlike Embodiment 1, the arc-shaped buffer plate 403 has an impact-resistant component 600 at the end away from the shaft 401. The impact-resistant component 600 includes an arc-shaped baffle 601, an elastic rubber pad 602 at the lower end of the arc-shaped baffle 601, and several connecting rods 603 fixed at the lower end of the arc-shaped baffle 601. The lower ends of the connecting rods 603 slide through the elastic rubber pad 602 and the arc-shaped buffer plate 403. The arc-shaped buffer plate 403 has mounting holes 410 for mounting the connecting rods 603. A limit block 604 is fixed at the lower end of the connecting rods 603. In use, when a large rock rolls down the slope 200, the rock will first contact the arc-shaped baffle 601. Through the elastic action of the elastic rubber pad 602, the initial buffering of the rock's impact force is achieved, thereby reducing the impact force of the rock on the arc-shaped baffle 601 itself. Example 3

[0038] Unlike Embodiment 1, the water collection chamber 405 is equipped with a filter assembly 700. The filter assembly 700 includes a rotating shaft 701 rotatably mounted on the partition plate 404 near the shaft 401 and a positioning rod 702 arranged parallel to the rotating shaft 701. A rigid filter screen 703 is fixed between the positioning rod 702 and the rotating shaft 701. The partition plate 404 is provided with a slot 411 matching the positioning rod 702 at the end away from the shaft 401. In use, the filter assembly 700 intercepts debris such as leaves, preventing them from clogging the water leakage channel 406 in the water collection chamber 405 and affecting the normal operation of the rock-blocking assembly 400.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
