[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. 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.
[0023] Embodiment 1:
[0024] Reference Figure 1 to Figure 2 As shown, this embodiment provides a protective device located on the road below the construction bridge, which is used to protect the road below the construction bridge to prevent falling objects from the top construction bridge and objects rolling down from the mountain from affecting the road below and vehicles traveling on the road. The device includes a first intercepting member 4, which is covered on the road 2 below the construction bridge 1, and a tunnel 3 for vehicles to travel is formed between the first intercepting member 4 and the road 2.
[0025] More specifically, the first interception member 4 includes a plurality of steel arch frames 41 and an interception net 43. The plurality of steel arch frames 41 are arranged at intervals along the road 2. Adjacent steel arch frames 41 are connected to each other through a plurality of reinforcing rods 42. The plurality of steel arch frames 41 are covered with an interception net 43. The plurality of steel arch frames 41 are consistent with the steel arch frames used in the tunnel. They are arranged at intervals along the direction of the road. They are mainly in the shape of a circular arch. Their two ends are respectively located on the left and right sides of the road 2. The plate surface of the steel arch frame 41 is perpendicular to the direction of the road 2. Adjacent steel arch frames 41 are connected and fixed to each other through a plurality of reinforcing rods 42 arranged at intervals. The reinforcing rods 42 are parallel to the direction of the road 2, thereby jointly forming a circular arch support frame. The interception net 43 is then laid and fixed on the support frame. The interception net 43 is made of a steel wire rope net or a ring net. A layer of wire grille can also be added to intercept small pieces of falling rocks, thereby forming the first interception member 4 as a whole to prevent falling objects from affecting the driving safety on the road 2 during the construction of the top bridge.
[0026] like Figure 1 and 2 As shown, the second intercepting member 5 has a plate-shaped intercepting portion, the second intercepting member 5 is vertically arranged on both sides of the first intercepting member 4, and is fixed to the first intercepting member 4; the second intercepting member 5 includes a plurality of anchor columns 51 and a plurality of guardrails 52, the plurality of anchor columns 51 are arranged on the ground at intervals, an anchor column 51 is connected to a steel arch frame 41, and a plurality of guardrails 52 are horizontally arranged and vertically installed on the plurality of anchor columns 51 at intervals.
[0027] In specific implementation, after the first intercepting member 4 is set up, an anchor column 51 is fixed on both sides of each steel arch frame 41, and guardrails 52 are laid in sequence from bottom to top between adjacent anchor columns 51 to form an anti-collision guardrail, which is used to intercept driving safety while being the final line of defense to intercept larger rolling stones on the mountain. It should be noted that the anchor column 51 is driven into the ground with a steel pipe machine as much as possible, which has a higher supporting strength and provides lateral protection for the first intercepting member 4.
[0028] like Figure 1 As shown in and , it also includes a third interceptor 6, which has a plate-shaped interception portion; the third interceptor 6 is arranged on the side of the road 2 close to the mountain 9, the lower end of the third interceptor 6 is anchored to the ground, and the upper end of the third interceptor 6 is inclined toward the first interceptor 4 and connected to the upper end of the second interceptor 5, forming a triangular support structure while forming an inclined interception portion. It should be noted that the plate surface of the third interceptor 6 needs to be perpendicular to the slope of the mountain to ensure the interception strength and effect.
[0029] In specific implementation, the third interception member 6 is a passive protection net, in which the upper end of the steel column 61 is connected to the upper end of the anchor column 51. The third interception member 6 is used as a preliminary interception component of the mountain body, and is used for preliminary and main interception of objects rolling down the mountain body. The passive protection net is composed of four main parts: a steel wire ring net 62 (a steel wire rope net or a ring net, with an additional layer of wire grid when small pieces of falling rocks need to be intercepted), a fixing system (anchor rods 65, anchor ropes 63, base and support ropes), a decompression ring 64 and a steel column 61. The steel column 61 and the steel wire ring net 62 are connected and combined to form a whole, forming a surface protection for the protected area, thereby preventing the collapse of rock and soil from falling, and playing a role in slope protection.
[0030] like Figure 1 As shown, a plurality of reinforcing members 7 are provided on the side of the first intercepting member 4 away from the mountain 9, the lower end of the reinforcing member 7 is anchored to the ground, and the upper end of the reinforcing member 7 is inclined toward the side of the first intercepting member 4 and connected to the upper end of the second intercepting member 5, forming a triangular support structure, which makes the overall structural strength higher. The reinforcing members 7 support the side of the first intercepting member 4 away from the mountain, thereby limiting and reinforcing the first intercepting member 4, and the overall structure of the first intercepting member 4 is more stable.
[0031] More specifically, there are a plurality of tunnels 3, and adjacent tunnels 3 are separated by support walls 8, and the upper ends of the support walls 8 are connected to the first intercepting member 4. In specific implementation, Figure 1 and 3 As shown, according to the width of the road 2 and the number of lanes, a corresponding number of tunnels 3 are provided, and the structural strength of the first interceptor 4 with a relatively large span can be maintained by the supporting wall 8 .
[0032] Embodiment 2:
[0033] Based on the first embodiment, when there are mountains on both sides of the road 2, the following method is adopted: Figure 3 The scheme shown, i.e., another third interception member 6 is provided on the side of the first interception member 4 away from the third interception member 6, and the two third interception members 6 are symmetrically arranged with respect to the first interception member 4. Both sides are intercepted by a third interception member 6 for rolling objects from the mountain, and combined with the second interception members 5 on both sides, a good interception system is formed to jointly protect the driving safety on the road 2.
[0034] In summary, the first interception member 4, the second interception member 5 and the third interception member 6 are all set and fixed on the ground, and their installation and removal are simple, fast and safe, without the need for high-altitude installation, and the cost is low; while the first interception member 4 intercepts and protects the top of the road 2, the second interception member 5 and the third interception member 6 form a triangular support structure and two interception panels, which together intercept and protect the side of the road 2, and form a limiting reinforcement and protection for the first interception member 4.
[0035] Embodiment three:
[0036] Based on embodiments one and two, the structures of the above two embodiments are only used when there is a rebuilt highway bridge above the road and there are mountains on the side. When there is only a rebuilt highway bridge above the road 2, the first intercepting member 4 and the second intercepting member 5 can be combined, and the third intercepting member 6 can be replaced by reinforcement members on both sides of the first intercepting member 4; and when there is only a mountain, the third intercepting member 6 alone or the third intercepting member and the second intercepting member 5 are combined.
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
