Description

Technical Field

[0001] This utility model relates to the field of cliff-side road widening technology, and in particular to a widening structure suitable for cliff-side roads in mountainous areas. Background Technology

[0002] my country has a vast territory, and the western region has steep mountains. There are many roads that run along the mountains. Due to terrain limitations, such as being near cliffs, rivers, or having steep inner mountains, and the difficulty of large-scale excavation to reduce engineering investment during road construction, the existing roads are relatively narrow. When encountering vehicles with wider sides, it is difficult for them to pass each other. Therefore, there is an urgent need to propose an economical, practical and feasible solution to address these common problems.

[0003] In the current solutions, traditional embankment widening may damage the original mountain structure and increase the risk of landslides; while widening by excavation along the inner side of the road has the problems of large excavation and support volume, corner excavation, and even affecting the stability of the mountain. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a widening structure suitable for mountainous roads along cliffs that ensures the safety of the widened road, the stability of the structure, and the feasibility of construction conditions.

[0005] The present invention provides a technical solution for a widening structure suitable for mountainous cliff-side roads: It includes a widening steel plate, with a guardrail installed at the upper part of one end of the widening steel plate and a support assembly at the other end. The support assembly includes two or more trapezoidal blocks on the outer wall of the widening steel plate away from the guardrail, tie rods installed between the trapezoidal blocks on the side wall of the widening steel plate, and a lag plate at the other end of the tie rods. Square plates are installed on the front and rear outer walls of the widening steel plate near the trapezoidal blocks. A support column is installed at the lower part of the widening steel plate, with its upper end fixedly connected to the widening steel plate and its lower end fitted with a nail plate. A zipper is fitted on the outer wall of the support column, with the other end of the zipper connected to a reinforcing steel frame. The head of the zipper is fitted on the outer wall of the reinforcing steel frame, and reinforcing steel columns are installed on the inner wall of the reinforcing steel frame.

[0006] Furthermore, the upper surface of the widened steel plate is arc-shaped, and the upper surface of the widened steel plate near the trapezoidal block is higher than the upper surface of the widened steel plate near the guardrail.

[0007] Furthermore, a drainage groove is provided on the side of the widened steel plate closest to the guardrail.

[0008] Furthermore, a raised strip is provided on the lower part of the side of the widened steel plate near the guardrail.

[0009] Furthermore, a pointed cone is provided at the bottom of the widened steel plate.

[0010] Furthermore, the pull rod head is provided with two sets of hysteresis plates, which are arranged in a mirror image.

[0011] Furthermore, the support columns are in two sets.

[0012] The beneficial effects of this utility model's widening structure for mountain roads along cliffs are:

[0013] I. This widening structure for mountain roads along cliffs, by setting up support components, trapezoidal blocks and delay plates, allows for a larger contact area between the newly poured concrete on the side of the mountain and the extended steel plate. At the same time, the inclined surface of the trapezoidal blocks can also suppress the tendency of the extended steel plate to move away from the mountain, effectively preventing the extended steel plate from detaching due to external forces when laid on the side of the mountain, and ensuring the safety of the road formed by the extended steel plate.

[0014] II. This widening structure for mountain roads along cliffs improves the load-bearing strength of the end of the extended steel plate away from the trapezoidal block by setting up a steel frame and connecting the steel frame to the support column through cables. This allows the middle part of the support column to also be subjected to the tensile force of the concrete paved on the road surface on the side of the mountain, ensuring the support strength of the support column and thus ensuring the load-bearing capacity of the extended steel plate during use, and ensuring driving safety.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] This utility model relates to a widening structure suitable for mountain roads along cliffs, such as... Figure 1 — Figure 5 As shown, the structure includes a widened steel plate 1. A guardrail 2 is installed on the upper part of one end of the widened steel plate 1, and a support assembly is installed on the other end of the widened steel plate 1. The support assembly includes two or more trapezoidal blocks 31 installed on the outer wall of the side of the widened steel plate 1 away from the guardrail 2. The trapezoidal blocks 31 are evenly distributed in a linear array on one side of the widened steel plate 1. The trapezoidal blocks 31 are narrower at the end near the widened steel plate 1 and wider at the end away from the widened steel plate 1. Tie rods 34 are installed on the side wall of the widened steel plate 1 between the trapezoidal blocks 31. A hysteresis plate 35 is installed at the other end of the tie rods 34, so that the tie rods 34 and the hysteresis plate 35 can work together with the trapezoidal blocks 31 to improve the connection stability and anti-displacement effect between the widened steel plate 1 and the concrete on the road on the side of the mountain. Square plates are respectively installed on the front and rear outer walls of the widened steel plate 1 on the side near the trapezoidal blocks 31. 32. A support column 36 is provided at the lower part of the widened steel plate 1. The upper part of the support column 36 is fixedly connected to the widened steel plate 1. A nail plate 37 is provided at the lower part of the support column 36. The nail plate 37 has a through hole. Fixing steel nails are used to pass through the through hole to fix the nail plate 37 to the surface of the mountain, providing a stable support effect for the widened steel plate 1 and the support column 36. A zipper 38 is fitted on the outer wall of the support column 36. The other end of the zipper 38 is connected to the steel reinforcement frame 39. The head of the zipper 38 is fitted on the outer wall of the steel reinforcement frame 39. The steel reinforcement frame 39 is set on the original road on one side of the mountain, and sufficient space is excavated downward to completely place the steel reinforcement frame 39 into the roadbed. Several steel reinforcement columns 310 are set on the inner wall of the steel reinforcement frame 39. The setting of several steel reinforcement columns 310 enhances the tensile strength of the road surface concrete.

[0023] Furthermore, the upper surface of the widened steel plate 1 is arc-shaped, and the upper surface of the widened steel plate 1 on the side near the trapezoidal block 31 is higher than the upper surface of the widened steel plate 1 on the side near the guardrail 2. The higher upper surface of the widened steel plate 1 on the side near the trapezoidal block 31 (when the widened steel plate is erected on the road on the mountainside, the side closer to the mountainside is higher), and the lower side of the widened steel plate 1 (the side of the widened steel plate away from the mountainside is lower), which is conducive to drainage to the outside of the mountainside and avoids rainwater accumulation, which would affect the driving safety of the mountain road.

[0024] Furthermore, a drainage channel 11 is provided on the side of the widened steel plate 1 near the guardrail 2. The drainage channel 11 allows rainwater to drain out.

[0025] Furthermore, a raised strip 12 is provided on the lower part of the side of the extended steel plate 1 near the guardrail 2. The raised strip 12 prevents rainwater flowing down the surface of the extended steel plate 1 from flowing along the bottom surface of the extended steel plate 1 towards the connection between the extended steel plate 1 and the road, thereby preventing the connection from being eroded and damaged by rainwater, which would affect the road safety after the extended steel plate 1 is installed.

[0026] Furthermore, the bottom of the extended steel plate 1 is provided with pointed cones 33. Multiple sets of pointed cones 33 are evenly distributed in a wave-like pattern on the bottom of the extended steel plate 1. With pointed cones 33, the contact area between the extended steel plate 1 and the road surface on the side of the mountain is increased, ensuring the grip of the extended steel plate 1.

[0027] Furthermore, the head of the tie rod 34 is provided with two sets of hysteresis plates 35, which are arranged in a mirror image. The two sets of hysteresis plates 35 are mirror-symmetrical in the shape of "<" and ">". With the hysteresis plates 35, the blocking effect of the hysteresis plates 35 on the tie rod 34 is increased, which effectively prevents the extended steel plate 1 from detaching due to external forces when it is laid on the road on the side of the mountain, and ensures the safety of the road formed by the extended steel plate 1.

[0028] Furthermore, the support columns 36 are in two sets. The two sets of support columns 36 are symmetrically arranged about the vertical central axis of the extension steel plate 1, thereby improving the stress strength of the end of the extension steel plate 1 away from the trapezoidal block 31.

[0029] This utility model discloses a widening structure suitable for mountain roads along cliffs. In use, the existing road on the mountainside is first leveled. Then, a groove half the thickness of the expansion steel plate 1 is excavated downwards on the side of the road away from the mountain. A through hole for the cable 38 to pass through is drilled in the mountainside using a drilling device. Next, a casting cavity is excavated downwards on the side of the road closer to the mountain, and a steel frame 39 and a steel column 310 are erected in the casting cavity. One end of the cable 38 is fitted onto the steel frame 39 using a ring structure, and then the cable 38 passes through the aforementioned through hole. Next, a nail plate 37 is fixed to the side of the mountainside on one side of the road using mechanical equipment, and the other end of the cable 38 is connected to the side of the support column 36. The tension of the cable 38 is adjusted. Then, the expansion steel plate 1 is laid in the assembly groove on the mountain road using hoisting equipment. Finally, concrete is poured on the existing road and at the connection between the existing road and the expansion steel plate 1, ultimately forming a widened structure on the mountain road along the cliff, facilitating vehicle passing and safe driving.
