TECHNICAL FIELD
[0001] The utility model relates to road engineering technical field especially a classification collection structure of side slope rockfall. BACKGROUND
[0002] When there is a natural gully on the side slope of the road which is perpendicular to the driving direction of the road, in order to keep the slope surface drainage smooth and maintain the stability of the side slope, a circular pipe culvert is generally buried under the road surface. The water collected on the slope surface of one side of the road can flow to the other side through the circular pipe culvert under the road bed, ensuring the smooth flow of water on the slope surface of the road on both sides. When there is a high side slope on both sides of the road, the catchment area of the side slope is large, and under the influence of heavy rain, the side slope is subjected to rainwater erosion, and the rocks on the slope surface are prone to rolling. During the rolling process of the rockfall along the slope surface, a large amount of potential energy is accumulated, and the rockfall will collide with trees and other rocks along the way, causing more objects to roll together. The diameters of the rocks on the slope surface are different, and the diameter of the large rocks can even reach 2m. When the other debris carried by the rockfall rolls into the circular pipe culvert, it will cause blockage, resulting in the water on the slope surface of the side slope cannot be discharged from the circular pipe culvert in time, and the water flows out of the road bed ditch and flows onto the road surface, causing waterlogging on the road. Moreover, when the potential energy accumulated by the large rock is large, it may cross the ditch and invade the road surface, which not only endangers the safety of the vehicles driving on the road, but also reduces the durability of the road surface.
[0003] In the prior art, in order to effectively protect the rockfall on the side slope, a net is generally hung on the slope surface. If a large rock with a large accumulated potential energy is encountered, the net is difficult to play a good blocking effect. The size of the rockfall intercepted by the net is different, and the large rockfall can even reach hundreds of kilograms, which is very difficult for the technical personnel to clean up. Secondly, the economic value and usefulness of large rockfall are much greater than those of small rockfall, and it is necessary to classify and collect the rockfall for the convenience of the technical personnel to classify and process.
[0004] Therefore, it is necessary to provide a classification collection structure of side slope rockfall to solve or at least alleviate the above-mentioned defects. CONTENT OF THE UTILITY MODEL
[0005] The main purpose of the utility model is to provide a classification collection structure of side slope rockfall to solve the technical problem of difficult rockfall cleaning and no classification collection in the prior art.
[0006] In order to achieve the above-mentioned purpose, the utility model provides a classification collection structure of side slope rockfall, which comprises a side slope and a ditch, the ditch is arranged at the bottom of the side slope, further comprises a guide round pile and a collection and distribution pit, the collection and distribution pit is arranged in the side slope, the guide round pile is fixed perpendicular to the slope surface of the side slope, the guide round piles are arranged in multiple rows and layers on the side slope, each row of guide round piles is inclined towards the entrance of the collection and distribution pit, the spacing and inclination angle of the guide round piles in the upper layer are greater than those in the lower layer, and a roller is further sleeved on the guide round pile.
[0007] Preferably, the entrance to the collection pit is shaped like an inverted trapezoid on the slope.
[0008] Preferably, the collection pit includes an inner wall, and the angle between the inner wall and the horizontal plane is less than or equal to 90 degrees.
[0009] More preferably, the collection pit also includes side walls, and mortar anchors are fixed inside the slope where the side walls and inner walls are located, and reinforced concrete is also laid on the side walls and inner walls.
[0010] Furthermore, the collection and distribution pit also includes a bottom surface, which is located on the same plane as the bottom of the inlet.
[0011] Furthermore, the guide pile is made of reinforced concrete.
[0012] Furthermore, the guide pile is embedded and fixed inside the slope, and the ratio of the length of the guide pile outside the slope to the length inside the slope is 4:6.
[0013] Furthermore, a pedestrian path leading to the entrance of the collection pit is also provided on the slope.
[0014] Furthermore, it also includes roads, and ditches are provided on the slopes. The ditches are set perpendicular to and connected to the slopes. A culvert is also provided inside the road at a position corresponding to the ditches. The inlet of the culvert is connected to the bottom of the ditches.
[0015] More preferably, a baffle is provided at the junction of the ditch and each row of guide piles, and the baffle covers the top of the ditch.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] This invention utilizes inclined guide piles to direct fallen rocks from a slope into a collection pit. Because multiple rows of guide piles are arranged in a staggered, layered manner on the slope, large rocks are guided into the collection pit before accumulating significant potential energy in the first layer. Smaller rocks enter the next layer of guide piles through gaps. Through this layered sorting process, only small rocks with minimal economic or practical value ultimately fall into the pit, preventing blockages and facilitating cleanup. Since the angle of inclination decreases from top to bottom, larger rocks in the upper layer travel faster and are distributed in the lower layer of the collection pit, while smaller rocks travel slower and are distributed in the upper layer. This categorized collection facilitates the cleaning and collection of rocks of different sizes by technicians. Attached Figure Description

[0029] Please see Figs. 1 to 3 This embodiment provides a classification and collection structure for slope rocks, including a slope 1 and a ditch. The ditch is located at the bottom of the slope 1. It also includes guide piles 2 and a collection pit 4. The collection pit 4 is located inside the slope 1. The bottom plane of the entrance of the collection pit 4 is higher than the road surface of the road 7, thereby preventing water in the ditch 3 from flowing back into the collection pit 4 during heavy rain, causing a large amount of water accumulation, which is not conducive to the cleaning and collection of rocks inside the collection pit 4 by technicians. The guide piles 2 are fixed to the slope 1 perpendicular to its surface. They are arranged in multiple rows on the slope 1 in a staggered, layered pattern. Each row of guide piles 2 is inclined towards the entrance of the collection pit 4. Through these inclined guide piles 2, falling rocks from the slope 1 are guided into the collection pit 4 for collection. Large rocks are guided into the collection pit 4 before accumulating significant potential energy when they land on the first layer. Smaller rocks enter the lower layer of guide piles 2 through gaps. This not only prevents large rocks from impacting and damaging the guide piles 2, but also prevents large rocks from crashing onto the road 7 due to excessive potential energy. The spacing and inclination angle of the upper row of guide piles 2 are greater than those of the lower row. Rollers 9 are also fitted around the guide piles 2. Because the inclination angle of the multi-row guide piles 2 decreases from the upper to the lower layer, the larger falling rocks in the upper layer move faster and are distributed in the lower layer of the collection pit 4, while the smaller falling rocks move slower and are distributed in the upper layer of the collection pit 4, thus achieving classified collection and facilitating the cleaning and collection of falling rocks of different sizes by technicians.
[0030] Specifically, the guide pile 2 has a diameter of 20 cm, and the roller 9 is a plastic roller with a thickness of 10 cm. The length of the roller 9 is the same as the length of the guide pile 2 outside the slope 1, and the roller 9 rolls on the guide pile 2. The uppermost layer of guide piles 2 is set 10 to 12 meters away from the bottom of the side pit 3, and the center-to-center distance between adjacent guide piles 2 in the uppermost layer is 80 cm; the lowermost layer of guide piles 2 is set 5 to 6 meters away from the bottom of the side pit 3, and the center-to-center distance between adjacent guide piles 2 in the lowermost layer is 40 cm.
[0031] It should be noted that, in this embodiment, for the sake of ease of understanding and application by those skilled in the art, and from the perspective of structural simplification, the guide circular piles 2 are arranged in two rows, and the collection pit 4 is arranged in one. This does not mean that this is the optimal arrangement of this utility model. In different embodiments, different collection pits 4 can be arranged on both sides of the guide circular piles 2, with the two rows of guide circular piles 2 inclined toward different collection pits 4, so as to achieve separate collection of rocks of different sizes.
[0032] In this embodiment, the entrance to the collection pit 4 is further shaped like an inverted trapezoid on the slope. Because the upper guide piles 2 are spaced relatively far apart, large rocks are sorted and filtered out at the upper level before falling into the collection pit 4. Therefore, the larger upper area of the entrance is more conducive to the falling of large rocks. Secondly, the inverted trapezoidal structure is more stable, preventing collapse accidents during continuous heavy rain.
[0033] In this embodiment, the collection pit 4 further includes an inner wall 41, the angle between the inner wall 41 and the horizontal plane being less than or equal to 90 degrees. The inner wall 41 of the collection pit 4 faces the road 7, and the angle of less than or equal to 90 degrees ensures that the inner wall 41 does not provide a force towards the road 7 to the falling rocks, causing the falling rocks to roll out of the collection pit 4.
[0034] As an embodiment, and more preferably, the collection pit 4 further includes side walls 42. Mortar anchors are fixed inside the slope 1 where the side walls 42 and inner walls 41 are located, and reinforced concrete is laid on the side walls 42 and inner walls 41. Specifically, firstly, mortar anchors with a diameter of 22mm and a length of 4m are driven into the slope 1; then, a steel mesh with a diameter of 8mm is laid on the side walls 42 and inner walls 41; finally, C25 shotcrete is used to cover them. By further reinforcing the collection pit 4 with mortar anchors and reinforced concrete on the side walls 42 and inner walls 41, a collapse of the collection pit 4 can be prevented.
[0035] In one embodiment, the collection pit 4 further includes a bottom surface, which is located on the same plane as the bottom of the inlet 43. During heavy rain, rainwater will flow into the collection pit 4. The fact that the bottom surface and the bottom of the inlet 43 are on the same plane makes it less likely for rainwater to remain in the collection pit 4 and cause water accumulation, further facilitating the cleaning of the collection pit 4 by technicians.
[0036] In another embodiment, the guide pile 2 is made of reinforced concrete and is fixed inside the slope 1. The ratio of the length of the guide pile 2 outside the slope 1 to the length inside the slope 1 is 4:6. Specifically, the length of the guide pile 2 outside the slope 1 is 40 cm and the length inside the slope 1 is 60 cm, which improves the impact resistance of the guide pile 2.
[0037] Furthermore, a pedestrian path 5 leading to the collection pit 4 is provided on the slope 1, allowing technicians to enter the collection pit 4 and remove fallen rocks.
[0038] Furthermore, the system also includes a road 7, and a ditch 6 is provided on the slope 1. The ditch 6 is perpendicular to and connected to the slope 1. A culvert 8 is also provided inside the road 7 at a position corresponding to the ditch 6, and the inlet of the culvert 8 is connected to the bottom of the ditch. A baffle is also provided at the junction of the ditch 6 and each row of guide piles 2, covering the ditch 6. The ditch 6 facilitates the collection of rainwater on the slope 1, preventing excessive rainwater from flowing through loose geological areas. The culvert 8 can drain the rainwater in the ditch 6 in a timely manner, and the baffle prevents rocks from getting stuck in the ditch 6 and causing blockage.
[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
