Description

Technical Field

[0001] The invention relates to the technical field of passive protection, in particular to a protection structure for hillside collapse. Background Art

[0002] Landslide refers to the geological phenomenon that the rock and soil on a steep slope suddenly break away from the parent body under the action of gravity and collapse, roll and accumulate at the foot of the slope (or valley). This geological disaster not only endangers the safety of nearby residents and buildings, but may also cause dangerous substances such as falling rocks and mudslides to impact the road, causing traffic interruptions and casualties. Therefore, it is very necessary to protect mountains with unstable geological structures and rock properties.

[0003] In order to prevent the impact of hillside collapse and falling rocks on road traffic, in the prior art, a protective net is usually installed on the side of the road close to the mountain to intercept the falling rocks, prevent them from directly hitting the road, and reduce the direct impact and damage of the falling rocks on the road. In the traditional installation process, the installer needs to install the support rope first, and then climb on the high support rope to splice the single wire rope nets or ring nets one by one. This method has a great safety risk. It is difficult to maintain a stable body balance when climbing on the support rope, and falling accidents are prone to occur.

[0004] Moreover, in addition to being dangerous and cumbersome, the existing installation method is also highly dependent on the experience and skill level of the installers. Even experienced installers find it difficult to ensure that the tension of the protective net in each area is the same. Uneven tension can cause the surface of the protective net to become uneven or loose, thereby reducing the ability of the protective net to intercept falling rocks.

[0005] Therefore, a protective structure for hillside collapse is proposed to solve the above problems. Summary of the invention

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: A protective structure for landslides on a hillside, comprising: a base and a steel column fixedly connected to the upper surface of the base, wherein the base and the steel column are respectively provided with two, the tops of the two steel columns are respectively provided with upper fixing members, the upper surfaces of the two bases are respectively provided with lower fixing members, and one side of the base is provided with a follow-up spreading mechanism for facilitating manual installation of a protective net; The follow-up spreading mechanism includes a mounting rod 1 arranged on a steel column on one side, a U-shaped frame is arranged on one side of the mounting rod 1, wheels are rotatably connected to the left and right outer walls of the lower end of the U-shaped frame respectively, a disc is fixedly connected to one side of the U-shaped frame close to the lower end, a notch is opened on one side of the disc, a mounting rod 2 is inserted in the notch of the disc, a wire rope net is wrapped around the outer wall of the mounting rod 2, a limit frame with holes is symmetrically fixedly connected to the lower surface of the disc, and a screw is arranged at the lower end of the limit frame with holes.

[0007] Preferably, the upper and lower ends of the mounting rod 1 are rotatably connected with mounting rings respectively.

[0008] Preferably, the U-shaped frame is in an inverted U-shape, and handles are provided on the left and right outer walls of the U-shaped frame.

[0009] Preferably, the notch of the disc faces a direction of the mounting rod.

[0010] Preferably, the upper and lower ends of the second mounting rod are rotatably connected with mounting rings respectively.

[0011] Preferably, a through hole is provided at the lower end of the stop frame with a hole, and the through hole provided at the lower end of the stop frame with a hole is coaxial with the mounting rings at the lower ends of the second mounting rod.

[0012] The cam is a vertical cam which is connected to the bottom surface of the support frame, and the cam has two locking plates, which are respectively provided with locking holes at the positions corresponding to the locking buttons. The cam and the cam are respectively provided with locking holes at the positions corresponding to the locking buttons.

The cam and the cam are respectively provided with locking holes at the positions corresponding to the locking buttons. The cam and the cam are respectively provided with locking holes at the positions corresponding to the locking buttons. The cam and the cam are respectively provided with locking holes at the positions corresponding to the locking buttons. The cam

[0013] Preferably, the side surface of the protective plate is a right triangle.

[0014] Preferably, the top end of the convex plate is provided with a protrusion matched with the notch of the concave plate.

[0015] Preferably, the concave plate and the convex plate cooperate to form a mortise and tenon structure.

[0016] Compared with the prior art, the present invention provides a protective structure for slope collapse, which has the following beneficial effects: The wire rope net is spliced ​​in advance before leaving the factory or transportation and rolled up on the second installation rod. During the installation process, you only need to fix the first installation rod on the steel column first, then push the U-shaped frame to unfold the wire rope net, and finally fix the second installation rod on the steel column on the other side to complete the deployment of one side of the protective net, thereby realizing simple and efficient installation by a single operator. Not only does it not require multiple installers to climb high to splice the wire rope nets one by one, it also speeds up the outdoor installation speed and reduces the risk of outdoor high-altitude installation operations.

[0017] By ensuring that each roll of wire rope net is of equal length and that the spacing between steel columns is equal, standardization of installation is achieved. This not only facilitates the management and supervision of the installation process and improves installation efficiency and quality control, but also ensures that the installation specifications of the wire rope net in each area are unified and the appearance is neat. At the same time, the tension of the wire rope net between each steel column is the same, making its protective capability stable and reliable, and avoiding installation quality problems caused by too loose or too tight tension.

[0018] By setting the wheels at the bottom end of the U-shaped frame and placing the mounting rod 2 and the wire rope net in the disc, the heavy wire rope net can be easily moved manually during transportation and spreading, which reduces the difficulty of spreading the wire rope net. At the same time, the wire rope net always remains vertical during the movement of the U-shaped frame without sagging in the middle, thereby eliminating the need for operators to repeatedly pull and adjust the lateral tension.

[0019] The bottom end of the wire rope net is hooked by a curved hook and fits against the ground. At the same time, the entire bottom fixing structure is more stable and reliable through the snap connection of the concave plate and the convex plate and the fixation with the plate nails. Therefore, when falling rocks fall into the wire rope net, the bottom end of the wire rope net will not be impacted by gravity, resulting in gaps and holes between the bottom end of the wire rope net and the ground, further preventing subsequent falling rocks from falling through the gap between the bottom end of the wire rope net and the ground, thereby improving the protective performance of the wire rope net.

[0020] Through the setting of springs and buffer plates, when rocks fall due to hillside collapse first roll down to the surface of the buffer plate, the spring at the bottom of the buffer plate will be compressed, thereby initially buffering and absorbing the impact force of the falling rocks, thereby reducing the impact force directly borne by the wire rope net, ensuring that the wire rope net can effectively intercept the falling rocks, and when the falling rocks roll down and hit the surface of the plate with plate nails, the impact of the stones will cause the nail part of the plate nails to penetrate deeper into the ground, further increasing the stability of the overall connecting components.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0025] Example 1: Reference Figures 1 to 5A protective structure for landslides on a hillside, comprising: a base 1 and a steel column 101 fixedly connected to the upper surface of the base 1, two bases 1 and two steel columns 101 are respectively provided, upper fixing members 102 are respectively provided at the tops of the two steel columns 101, lower fixing members 103 are respectively provided on the upper surfaces of the two bases 1, and a follow-up spreading mechanism is provided on one side of the base 1 for facilitating manual installation of a protective net; The follow-up spreading mechanism includes a mounting rod 201 arranged on a steel column 101 at one side, and the upper and lower ends of the mounting rod 201 are rotatably connected with mounting rings. The mounting ring at the upper end of the mounting rod 201 can be plugged and fixed with the upper fixing member 102 through a latch rod, and the mounting ring at the lower end of the mounting rod 201 can be plugged and fixed with the lower fixing member 103 through a latch rod. A U-shaped frame 202 is arranged on one side of the mounting rod 201, and the U-shaped frame 202 is in an inverted U shape. The two ends of the U-shaped frame 202 are connected to each other. A handle is provided on the side outer wall, and wheels 203 are rotatably connected to the outer walls on both sides of the lower end of the U-shaped frame 202. A disc 204 is fixedly connected to one side of the U-shaped frame 202 near the lower end. A notch is provided on one side of the disc 204. The notch of the disc 204 faces the direction of the mounting rod 1 201. A mounting rod 205 is inserted into the notch of the disc 204. The mounting rod 205 is the same as the mounting rod 1 201. The upper and lower ends of the mounting rod 205 are rotatably connected to mounting rings. The mounting ring at the upper end of the second rod 205 can be plugged and fixed with the upper fixing piece 102 on the side away from the first mounting rod 201 through a latch rod, and the mounting ring at the lower end of the second mounting rod 205 can be plugged and fixed with the lower fixing piece 103 on the side away from the first mounting rod 201 through a latch rod. The outer wall of the second mounting rod 205 is wrapped with a wire rope net 104, one end of the wire rope net 104 is fixedly connected to the second mounting rod 205, and the other end of the wire rope net 104 is fixedly connected to the first mounting rod 201. The lower surface of the disk 204 is symmetrically fixedly connected with a hole limit frame 206, and a screw 207 is set at the lower end of the hole limit frame 206. A through hole is opened at the lower end of the hole limit frame 206. The through hole opened at the lower end of the hole limit frame 206 is coaxial with the mounting ring at the lower end of the mounting rod 205. The screw 207 is inserted into the mounting ring at the lower end of the mounting rod 205 and the through hole of the hole limit frame 206, and the screw 207 can be fixed on the hole limit frame 206 in conjunction with the nut.

[0026] When in use, the installation personnel will clear the obstacles such as debris, trees, weeds, etc. in the installation area in advance, then dig anchor holes, insert anchor rods into the rock and soil, and then inject concrete into the pre-buried anchor rods, and then embed the base 1 into the anchor bolts, tighten them with nuts, and then connect the steel column 101 to the base 1, and finally insert the fixing bolts and tighten them. The above is the preparatory work before the installation of the passive protection net and the fixation of the base 1 and the steel column 101.

[0027] Since the wire rope net 104 is rolled up on the installation rod 205, the length of each roll of the wire rope net 104 is equal. Therefore, when the installer fixes the base 1 and the steel column 101, the distance between the two steel columns 101 can be determined according to the length of the wire rope net 104. After the installer fixes the two bases 1 and the steel columns 101 respectively according to the length of the wire rope net 104, the installation personnel can refer to Figure 3 Since the outer wall of the second mounting rod 205 is wrapped with the wire rope net 104, the installer first slides the second mounting rod 205 into the notch of the disc 204, and then respectively passes the screws 207 through the through holes at the lower end of the hole-containing limit frame 206 and the mounting ring at the lower end of the second mounting rod 205, and fixes them with nuts. At this time, the wire rope net 104 is located on the U-shaped frame 202, and then you can refer to Figure 2 , fix the mounting rings at the upper and lower ends of the mounting rod 201 to the upper fixing piece 102 and the lower fixing piece 103 of the steel column 101 on one side, then grasp the handles on both sides of the U-shaped frame 202 to push the U-shaped frame 202 and the wire rope net 104 to move to the steel column 101 away from the side of the mounting rod 201. Since the mounting ring at the bottom end of the mounting rod 205 is a rotational connection, and the mounting ring at the lower end of the mounting rod 205 is fixed by the hole limit frame 206 and the screw 207 and cannot rotate, the rod body at the upper end of the mounting rod 205 can rotate, and since one end of the wire rope net 104 is fixedly connected to the mounting rod 1 201, during the movement of the U-shaped frame 202, the reeled end of the wire rope net 104 will gradually rotate and unfold. The unfolded state can be referred to Figure 5 When the U-shaped frame 202 drives the wire rope net 104 to move to the steel column 101 away from the installation rod 201, you can refer to Figure 3 , first loosen the nut on the screw 207, and then pull the screw 207 out of the mounting rod 205 and the hole-limiting frame 206. At this time, the mounting rod 205 is no longer limited in the hole-limiting frame 206. Therefore, you can refer to Figure 4 and Figure 5 Under the action of the notch of the disc 204, the installer only needs to push the U-shaped frame 202 in the direction away from the side of the installation rod 1 201 to separate the U-shaped frame 202 and the disc 204 from the installation rod 205, and a new wire rope net 104 and the installation rod 205 can be replenished and fixed in the U-shaped frame 202 and the disc 204 separated from the installation rod 205, and the installation rod 1 201 fixed to one end of the wire rope net 104 can be installed on the new steel column 101, so as to facilitate the subsequent installation of a new roll of wire rope net 104.

[0028] As for the installation rod 205 that is detached from the U-shaped frame 202 and the disc 204, the installer can fix the installation rings at the upper and lower ends of the installation rod 205 to the upper fixing piece 102 and the lower fixing piece 103 respectively. At this time, the rolled wire rope net 104 has been fully unfolded and forms a protective net between the two steel columns 101.

[0029] Furthermore, after the installers have installed a protective net on the side of the road close to the mountain, they can repeat the above steps at the steel column 101 close to the side of the second installation pole 205, install two new steel columns 101, and use the U-shaped frame 202 to spread a new wire rope net 104 inside the two steel columns 101, and repeat this process back and forth, thereby laying a large area of ​​protective net on the side of the road close to the mountain, thereby protecting the road and moving vehicles.

[0030] Therefore, the steel wire rope net 104 is spliced ​​in advance and rolled up on the second installation rod 205 before leaving the factory or being transported. During the installation process, it is only necessary to first fix the first installation rod 201 on the steel column 101, and then push the U-shaped frame 202 to unfold the steel wire rope net 104, and finally fix the second installation rod 205 on the steel column 101 on the other side to complete the deployment of one side of the protective net, thereby realizing simple and efficient installation by a single operator. Not only does it not require multiple installers to climb high to splice the steel wire rope nets 104 one by one, it also speeds up the outdoor installation speed and reduces the risk of outdoor high-altitude installation operations.

[0031] At the same time, by setting the length of each roll of wire rope net 104 equal and the spacing between steel columns 101 equal, standardization of installation is achieved, which not only facilitates the management and supervision of the installation process and improves installation efficiency and quality control, but also ensures that the installation specifications of the wire rope net 104 in each area are unified and the appearance is neat. At the same time, it ensures that the unfolding tension of the wire rope net 104 between each steel column 101 is the same, making its protection capability stable and reliable, and avoiding installation quality problems caused by too loose or too tight tension.

[0032] Furthermore, by providing the wheels 203 at the bottom end of the U-shaped frame 202, and placing the mounting rod 205 and the wire rope net 104 in the disc 204, the heavy wire rope net 104 can be easily moved manually during transportation and spreading without expending a lot of physical effort, thereby reducing the difficulty of spreading the wire rope net 104. At the same time, during the movement of the U-shaped frame 202, the wire rope net 104 always remains vertical without sagging in the middle, thereby eliminating the need for operators to repeatedly pull and adjust the lateral tension.

[0033] Embodiment 2: Based on the above embodiment 1, refer to Figure 4 , Figures 6 to 10The steel column 101 is provided with a buffering and stabilizing mechanism for improving the stability of the protective net. The buffering and stabilizing mechanism includes a concave plate 301 rotatably connected to the steel column 101 on the side close to the mounting rod 201. Specifically, the concave plate 301 is located on the side where the two steel columns 101 are close to each other, and the bottom of the steel column 101 close to the mounting rod 201 is fixed with two side plates, and the bottom of the concave plate 301 is rotatably connected between the two side plates. A notch is provided at the top of the concave plate 301, and a convex plate 302 is rotatably connected to the other steel column 101. Specifically, the bottom of the other steel column 101 is also fixed with two side plates, and the bottom of the convex plate 302 is rotatably connected between the two side plates. The convex plate 302 is located on the side close to the second mounting rod 205, and a convex block is provided on the top of the convex plate 302 to match the notch of the concave plate 301. The concave plate 301 and the convex plate 302 remain vertical in the initial state, and the concave plate 301 and the convex plate 302 cooperate to form a mortise and tenon structure. One side wall of the two steel columns 101 is rotatably connected with a lock buckle 303, and the lock buckle 303 is initially blocked in front of the concave plate 301 and the convex plate 302. The concave plate 301 and the convex plate 302 are respectively provided with lock holes 304 at the corresponding positions of the lock buckle 303, and the shape of the lock hole 304 is matched with the shape of the lock buckle 303. Specifically, the lock buckle 303 and the lock hole 304 are both rhombus-shaped, and when the lock buckle 303 is in a horizontal state, the concave plate 301 and the convex plate 302 can be kept in a vertical state. The concave plate 301 and the convex plate 302 are fixedly connected with a plurality of hooks 305 at equal intervals on one side close to the mounting rod 205, and the concave plate 301 and the convex plate 302 are equally spaced on one side away from the hooks 305, and a plurality of flat slots 306 are opened at equal intervals on one side, and the concave plate 301 is fixedly connected with a limiting plate 307 on one side close to the flat slot 306, wherein the limiting plate 307 is located between the concave plate 301 and the convex plate 302 when the concave plate 301 and the convex plate 302 are flipped downward to a horizontal state when they are close to each other. A plurality of vertical slots 308 are equidistantly provided in the limiting plate 307 corresponding to the flat slots 306, and a plate nail 309 is inserted in the vertical slots 308. Specifically, the plate nail 309 is composed of a plate body and steel nails evenly fixedly connected to a side of the plate body near the vertical slots 308, and the plate nail 309 is inserted in the vertical slots 308 through the steel nails. The plate nail 309 can be fixed to the limiting plate 307 by tying a strap around the outer periphery of the plate nail 309 and the limiting plate 307.A protective plate 310 is fixedly connected to one side of the limiting plate 307 away from the concave plate 301, the side of the protective plate 310 is a right triangle, and a concave notch is provided on the side of the protective plate 310 close to the limiting plate 307, a row of springs 311 are fixedly connected at equal intervals on the bottom surface of the concave notch of the protective plate 310, and a buffer plate 312 is fixedly connected to the upper ends of the row of springs 311, the buffer plate 312 is located directly above the concave notch, and one side of the buffer plate 312 is in contact with the outer surface of the limiting plate 307, and the other side is in contact with the vertical surface of the concave notch.

[0034] During use, since the protective net formed by the spliced ​​wire rope net 104 is elastic and stretchable, the wire rope net 104 will shrink to a certain extent when it is rolled up. The wire rope net 104 can be pulled horizontally during the process of horizontally unfolding and fixing it in Example 1. On the one hand, in order to ensure that the wire rope net 104 is fully unfolded vertically, so as to ensure that the bottom of the wire rope net 104 is in better contact with the ground and reduce the gap between the bottom of the wire rope net 104 and the ground, on the other hand, in order to further ensure the firmness of the wire rope net 104 during use, after the wire rope net 104 is horizontally unfolded, the installer can pull the lower end of the wire rope net 104 toward the protective plate 310 to stretch the vertically contracted part of the wire rope net 104, and lay the extended part of the lower end after the wire rope net 104 is stretched in the direction of the protective plate 310, and then refer to Figure 7 and Figure 8 , rotate the lock buckles 303 in the two steel columns 101 by 90 degrees, and the lock holes 304 in the concave plate 301 and the convex plate 302 can pass through the lock buckles 303, so the concave plate 301 and the convex plate 302 can be turned down, and then refer to Fig. 9 and Fig.10 During the flipping process of the concave plate 301 and the convex plate 302, the hook 305 will be driven to flip synchronously. Since there is a distance between the hook 305 and the mounting rod 1 201 and the mounting rod 205, the wire rope net 104 fixed between the mounting rod 1 201 and the mounting rod 205 will not fit with the hook 305 when unfolded. Therefore, the hook 305 will not hook the surface of the wire rope net 104 during the flipping process. When the concave plate 301 and the convex plate 302 are turned over to the bottom, the hook 305 will pass through the mesh on the bottom extension of the wire rope net 104, so that the hook 305 will hook the bottom extension of the wire rope net 104. At this time, the protruding part of the convex plate 302 is just engaged in the notch of the concave plate 301. Since the concave plate 301 is fixedly connected with the limiting plate 307, the limiting plate 307 and the protective plate 310 will be turned down synchronously. At this time, the vertical notch 308 opened in the limiting plate 307 will be aligned with and connected to the flat notch 306 opened in the concave plate 301 and the convex plate 302. Therefore, when the installer uses scissors to cut the binding strap, the fixation between the plate nail 309 and the limiting plate 307 can be released, and then the plate The nail 309 is pushed straight into the flat slot 306 from the vertical slot 308, and a hammer is used to knock the board surface of the plate nail 309 until the plate end of the plate nail 309 fits with the surface of the concave plate 301 and the convex plate 302, thereby inserting the nail end of the plate nail 309 into the ground. At this time, the concave plate 301 and the convex plate 302 are firmly connected by the plate nail 309, and the bottom end of the wire rope net 104 is firmly hooked by the curved hook 305, fit to the ground, to avoid a gap between the bottom end of the wire rope net 104 and the ground.

[0035] Therefore, the bottom end of the wire rope net 104 is hooked into the ground by the curved hook 305, and at the same time, the entire bottom fixing structure is made more stable and reliable through the snap connection between the concave plate 301 and the convex plate 302 and the fixation with the plate nails 309. Therefore, when falling rocks fall into the wire rope net 104, the bottom end of the wire rope net 104 will not be impacted by gravity, resulting in gaps and holes between the bottom end of the wire rope net 104 and the ground, thereby preventing subsequent falling rocks from falling through the gap between the wire rope net 104 and the ground, thereby improving the protective performance of the wire rope net 104.

[0036] Also, please refer to Fig.10 When the rocks fall due to landslides on the slope and first roll onto the surface of the buffer plate 312, the spring 311 at the bottom of the buffer plate 312 will be compressed, thereby preliminarily buffering and absorbing the impact force of the falling rocks, thereby reducing the impact force directly borne by the wire rope net 104, ensuring that the wire rope net 104 can effectively intercept the falling rocks. When the falling rocks roll and impact the surface of the plate body of the plate nail 309, the impact of the stones will cause the nail part of the plate nail 309 to penetrate deeper into the ground, further increasing the stability of the overall connecting component.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
