Technical Field
[0001] This utility model relates to the technical field of auxiliary construction equipment for highway bridge piles, specifically a cross-road protective shed for artificial pile construction on steep terrain. Background Technology
[0002] During the construction of highway bridge piles, some extremely steep terrains are encountered where conventional machinery cannot reach the site, and drilling equipment cannot be properly placed. Therefore, conventional mechanical construction is difficult, and manual excavation of bored piles becomes the only option. Manually excavated bored piles involve manually digging holes, then placing the reinforcing cage, and finally pouring concrete. Because everything is done by hand, the cost is high and the efficiency is low. Therefore, minimizing excavation and backfilling work is the fundamental guiding principle of manual excavated bored pile construction. Furthermore, due to the steep terrain, ensuring the personal safety of construction personnel is also a key consideration in manual excavated bored pile construction. In existing literature, when using manhole-excavated pile foundations on steep slopes, most construction methods involve excavating the slope to form an operating platform, such as the paper "Construction Technology of Manhole-Excavated Pile Foundations for Bridges on Sloping Mountain Sections" ("Transportation Science and Management", pp. 55-57). However, this platform-forming method involves excessive excavation of the mountain, significant disturbance to the mountain, and high construction difficulty. Moreover, the operating platform area is limited, and the operation of tools and equipment is not convenient. Furthermore, according to the review, all existing manhole-excavated pile foundations are located in mountainous areas, and there has never been a precedent for combining manhole excavation with road protection sheds for collaborative construction.
[0003] With the continuous development of transportation networks, the construction of highway bridge piers on steep slopes using artificial drilling techniques is often necessary. Existing techniques for this type of construction require excavation to create a platform, causing significant disturbance to the mountain and posing a safety hazard to vehicles. Therefore, a protective canopy for artificial pile drilling on steep terrain needs to be designed to address this issue, reducing excavation, significantly decreasing manual labor, and resolving the safety concerns associated with such construction. Summary of the Invention
[0004] The purpose of this invention is to provide a road safety shed for manual pile driving on steep terrain. This road safety shed has a simple structure and ingenious design. Its application solves the problem of a platform for manual pile driving on steep slopes, reduces excavation of the mountain, significantly reduces the workload of manual labor, and also solves the problem of road construction safety for vehicles on steep slopes. Even without the need for large machinery, rapid construction can still be achieved manually.
[0005] This utility model is achieved using the following technical solution:
[0006] A roadside protective canopy constructed using artificial pile foundations for steep terrain includes an anchored retaining wall, steel pipe columns for the canopy, and a roof. The anchored retaining wall is constructed at the toe of the slope on the side of the artificially drilled hillside. The steel pipe columns for the canopy are positioned along the road on the side away from the hillside, spaced longitudinally along the road. The roof has a double-layer structure. The first layer consists of a first-layer main beam I-beam supported at both ends by the anchored retaining wall and the steel pipe columns for the canopy. A first-layer distribution beam I-beam is installed on the first-layer main beam I-beam, and wooden planks are laid on top of the first-layer distribution beam I-beam. Elevation beams are laid on the wooden planks, and a second-layer main beam I-beam of the second layer is laid on the elevation beams. A second-layer distribution beam I-beam is installed on the second-layer main beam I-beam, and steel plates are laid on top of the second-layer distribution beam. The roof, supported by the anchored retaining wall and the steel pipe columns for the canopy, forms a roadside protective canopy and serves as an operating platform.
[0007] A further preferred embodiment: the anchored retaining wall is poured in sections and drainage holes are pre-embedded. The retaining wall is poured to the design height range of the anchor rods, and anchor rods are driven into the inner side of the mountain before the remaining retaining wall is poured. When the last section of the retaining wall is poured, a steel plate is pre-embedded at the top for welding and fixing to the I-beam of the main beam of the cross-road protection shed; the steel plate is pre-embedded along the position of the I-beam of the first layer distribution beam.
[0008] A further preferred embodiment: the anchor retaining wall has three layers of anchors driven into the slope of the artificially drilled mountain side, the three layers of anchors are arranged in an upper and lower structure, and the anchor retaining wall is provided with two layers of drainage holes, which are also arranged in an upper and lower structure.
[0009] A further preferred embodiment: the bottom of the protective shed steel pipe column is provided with a strip concrete foundation, and the top of the strip concrete foundation is pre-embedded with a pre-embedded steel plate for welding with the protective shed steel pipe column; channel steel is provided between the protective shed steel pipe columns as scissor bracing to increase the overall stability of the protective shed.
[0010] A further preferred embodiment: the steel plate is surrounded by a steel pipe guardrail.
[0011] A further preferred embodiment: sandbags, serving as a buffer material for rolling stones, are placed within the top area of the retaining wall on the steel plate.
[0012] A further preferred embodiment: the top surface of the steel plate is connected to a waste chute on the side away from the mountain, the upper end of the waste chute is supported on the steel plate, and the lower end extends to be supported on the ground.
[0013] This artificial pile-driving cross-road protective shed structure on steep terrain is simple and ingeniously designed. It utilizes an anchored retaining wall and steel pipe columns supporting the roof to form the cross-road protective shed, which also serves as an operating platform for construction on steep slopes and downhill sections. Under limited excavation conditions, the platform area is maximized. The cross-road protective shed platform structure is stable and, after verification, can fully support the weight of tools, equipment, and personnel required for manual pile-driving, ensuring safety during both manual pile-driving and downhill driving. Unlike existing platform structures for artificial pile-driving on steep terrain, this method solves the problem of operating platforms for manual pile-driving on steep slopes by constructing a cross-road protective shed tunnel, reducing excavation of the mountainside, significantly reducing manual labor, and addressing the safety concerns of vehicles during manual pile-driving on steep slopes. Even without the need for large machinery, rapid construction can still be achieved manually. Attached Figure Description

[0020] A roadside protective canopy constructed using artificial pile foundations on steep terrain includes an anchored retaining wall 2, protective canopy steel pipe columns 16, and a roof. The anchored retaining wall 2 is constructed at the toe of the slope on one side of the artificially drilled hillside. The protective canopy steel pipe columns 16 are positioned along the road on the side away from the hillside, spaced longitudinally along the road. The roof has a double-layer structure. The first layer consists of a first-layer main beam I-beam 5 supported at both ends by the anchored retaining wall 2 and the protective canopy steel pipe columns 16, respectively. A first-layer distribution beam I-beam 6 is installed on the first-layer main beam I-beam 5, and wooden planks 7 are laid on the first-layer distribution beam I-beam 6. A raised beam 14 is laid on the wooden planks 7, and a second-layer main beam I-beam 13 of the second layer structure is laid on the raised beam 14. A second-layer distribution beam I-beam 12 is installed on the second-layer main beam I-beam 13, and steel plates 11 are laid on the second-layer distribution beam I-beam 12.
[0021] The steel plate 11 is surrounded by a steel pipe guardrail 9.
[0022] Sandbags 10, which serve as buffer material for rolling stones, are placed within the top area of the retaining wall on the steel plate 11.
[0023] The construction and application process of the artificially piled road protection canopy in this steep terrain is as follows:
[0024] A. Clear the slope toe of the artificially drilled hillside and construct an anchored retaining wall 2. The anchored retaining wall 2 is poured in sections with pre-embedded drainage holes 3. The retaining wall is poured to the designed height range of the anchors 4. Anchors 4 are driven into the inner side of the hillside, and then the remaining retaining wall is poured. During the pouring of the last section of the retaining wall, a steel plate is pre-embedded at the top for welding and fixing to the I-beam of the main beam of the cross-road protection shed; the steel plate is pre-embedded along the position of the I-beam of the main beam of the cross-road protection shed. The anchored retaining wall 2 has three layers of anchors 4 driven into the slope of the artificially drilled hillside. The three layers of anchors 4 are arranged in an upper and lower structure. The anchored retaining wall 2 has two layers of drainage holes 3 inside, which are also arranged in an upper and lower structure.
[0025] B. Construct a strip concrete foundation 18 along the roadside on the side away from the mountain. A steel plate 17 is pre-embedded on the top of the strip concrete foundation 18, and protective canopy steel pipe columns 16 are welded onto the pre-embedded steel plate 17. The protective canopy steel pipe columns 16 are arranged at longitudinal intervals along the road, and channel steel is installed between the protective canopy steel pipe columns 16 as scissor bracing 19 to increase the overall stability of the protective canopy.
[0026] C. Anchor retaining wall 2 and steel pipe column 16 of protective shed are used as supports to build a canopy to become a road crossing protective shed and an operating platform.
[0027] D. Install the pre-processed waste chute 15 on the side of the cross-road protection shed away from the mountain. One side of the waste chute 15 is supported on the top panel of the cross-road protection shed, and the other side extends to be supported on the ground.
[0028] E. At the top of the anchor retaining wall 2, within the range of the artificial pile hole 1, a double-row scaffold 8 is erected. The uphill excavation is carried out by manual labor and small machinery. The slag sample from the excavated mountain is transported to the top of the spoil chute by a hand-pushed slag hopper placed on the top of the road protection shed. The slag sample is then transported to the ground and piled up. The work is repeated until the uphill excavation is completed and the artificial hole-forming operation platform is completed.
[0029] F. Protect the rock surface 20 on the upslope of the mountain according to its condition. If the rock surface 20 is a loose layer, embed steel mesh into the shotcrete on the slope, and add several anchor rods to the surface of the shotcrete, anchoring the anchor rods into the rock surface. If the rock surface 20 is a hard rock surface, due to the stable terrain structure, the above reinforcement structure is not required; it is sufficient to prevent falling rocks from injuring people. Ensure the safety of construction on the operating platform.
[0030] G. Install a manual drilling lifting device on the top of the roof and start the manual drilling operation. The slag sample from the manhole is transported to the top of the waste chute by a hand-pushed slag hopper placed on the top of the roof, and then the slag sample is transported to the ground and piled up. Repeat the work until the manual drilling is completed.
[0031] The above description is not intended to limit the present utility model, nor is the present utility model limited to the above examples. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
