Description

Technical Field

[0001] This invention belongs to the technical field of bridge construction auxiliary equipment, specifically relating to a prefabricated steep slope transport channel system and construction method. Background Technology

[0002] With technological advancements and economic development, the demand for national infrastructure construction is also increasing. Among infrastructure projects, bridges, as important structural elements connecting canyons and spanning rivers, play a vital role in transportation engineering. Bridge construction environments are complex, and it is difficult to avoid construction work on steep cliffs and slopes in mountainous areas. To facilitate the transportation of materials, it is necessary to build temporary access roads in the mountains.

[0003] However, excavating access roads on steep slopes is difficult and costly. Furthermore, vehicles traveling on these excavated access roads are prone to overturning and other accidents, leading to serious consequences and posing significant safety hazards. Additionally, excavating access roads on steep slopes can easily damage the surrounding environment, which is difficult to restore, thus impacting the local ecosystem. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated steep slope transport channel system that can replace excavated access roads. Its installation and construction cause little disturbance to the surrounding environment, can restore the surrounding ecology in a timely manner, and meets the requirements of green and environmentally friendly construction.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A prefabricated steep slope transport channel system includes a load-bearing system and a transport system, providing a transport platform for construction. The load-bearing system includes a foundation, columns, crossbeams, and longitudinal beam tracks. The columns are set on the foundation, two longitudinal beam tracks are erected on top of the columns, and the crossbeams are connected at the bottom of the two longitudinal beam tracks. A pedestrian walkway is also provided on the crossbeams. The transport system includes a concrete pump pipe, a transport trolley that can slide on the longitudinal beam tracks, and a boom crane. The transport trolley and boom crane are both installed on the longitudinal beam tracks. The concrete pump pipe is installed and supported on the crossbeams or longitudinal beam tracks through a pump pipe support structure, and the concrete pump pipe is arranged along the length of the longitudinal beam tracks.

[0007] A further preferred embodiment: a transverse connecting rod connects the two adjacent columns at the bottom of the crossbeam.

[0008] A further preferred embodiment: The foundation includes a foundation base and an anchor bolt assembly, wherein the foundation base is fixed to the ground by the anchor bolt assembly. During construction, a soil drilling rig is used to drill holes, geological conditions are analyzed, the foundation base is poured, anchor piles are then driven in, followed by the installation of columns, and the erection of crossbeams, longitudinal beam tracks, and diagonal braces to form the main load-bearing structure of the first segment.

[0009] A further preferred embodiment: the column is also connected to the adjacent crossbeam via diagonal bracing. The diagonal bracing is adjustable in length to adapt to different slopes and terrain.

[0010] A further preferred embodiment: the top of the column is hinged to the bottom of the longitudinal beam track via a hinge support.

[0011] A further preferred embodiment: the two sections of the longitudinal beam track of each longitudinal beam track are connected by a longitudinal beam track pin hinge, which includes a front hinge lug, a rear hinge lug, and a pin. The front hinge lug is located at the front end of the rear section of the longitudinal beam track, and the rear hinge lug is located at the rear end of the front section of the longitudinal beam track. The front hinge lug and the rear hinge lug are hinged by a pin.

[0012] A further preferred embodiment: the pedestrian walkway includes treads and guardrails, with guardrails installed on both sides of the treads and anti-roll-off baffles installed on the treads.

[0013] A further preferred embodiment features a cover plate on the top of the transport trolley frame, a bottom door at the bottom of the frame, anti-tipping wheels at the bottom of the frame for sliding on the longitudinal beam rails, and side doors on the sides of the frame. The transport trolley can be moved on the longitudinal beam rails by a winch rewinding mechanism, or a remote-controlled motor drive device can be installed on the frame to drive the wheels, allowing it to move on the longitudinal beam rails.

[0014] A further preferred embodiment: the pump pipe support structure includes a pump pipe support base, a pump pipe support hinge seat is provided on the pump pipe support base, a screw sleeve is hinged to the pump pipe support base, a height adjustment screw is internally threaded to the screw sleeve, a pump pipe sleeve clamp is provided at the top of the height adjustment screw, and a turnbuckle is connected between the upper end of the screw sleeve and the pump pipe support base, so that the height and angle of the pump pipe support structure can be adjusted.

[0015] A further preferred embodiment: the derrick crane includes a movable base, the bottom of which is provided with anti-overturning pulleys for sliding on the longitudinal beam track. A fixed rod and a rotating rod are provided on the movable base via supports. The top ends of the fixed rod and the rotating rod are connected to a force-sharing steel wire rope. A steel wire rope for hoisting materials is guided on the rotating rod. The end of the steel wire rope is connected to a hook. The movable base is provided with a limiting ear for fixing and limiting the movable base.

[0016] The anti-overturning wheels and anti-overturning pulleys described above can have the same structure. A roller for sliding on the top of the longitudinal beam track is installed on the wheel frame, and two sets of limiting wheels for sliding on both sides of the bottom of the longitudinal beam track are installed on the wheel frame. The two sets of limiting wheels are arranged in front and behind below the roller to form a triangular limiting sliding structure.

[0017] The installation and construction process of the prefabricated cliff and steep slope transport channel system is as follows:

[0018] The first step is to construct the main load-bearing structure. Holes are drilled using a soil drilling rig, geological conditions are analyzed, the foundation base is poured, anchor piles are then driven in, columns are installed, and horizontal beams, longitudinal beams, and diagonal braces are erected to form the first segment of the main load-bearing structure.

[0019] The second step is to install the boom crane and transport trolley on the longitudinal beam track.

[0020] The third step is the installation of other structures. Materials are transported and unloaded using a derrick crane and transport trolleys, and the pedestrian walkways, guardrails, and concrete pump pipes are installed, completing the installation of the first structural segment.

[0021] The fourth step involves using a transportation and loading / unloading system to transport construction materials such as steel and concrete to the end of the installed segments. This process is repeated from the first to the third step until the entire system is installed.

[0022] The dismantling and construction process is as follows:

[0023] The first step is the dismantling of the remaining structures in the final segment. Using a derrick crane and transport trolleys, the final segment of the pedestrian walkway, guardrails, concrete pump pipes, and other structures are dismantled and transported to the starting point.

[0024] The second step is to move the transport trolley to the penultimate section and fix the boom crane to the end of the penultimate section's load-bearing structure.

[0025] The third step is the dismantling of the main load-bearing structure of the final segment. The main load-bearing structure of the final segment is dismantled from top to bottom. The dismantled longitudinal beams, transverse beams, and column segments are transported to the foot of the mountain using transport trolleys. They are transported as they are dismantled and then neatly stacked and stored in a warehouse at the foot of the mountain for reuse.

[0026] Fourth, after the last section of the load-bearing structure is dismantled, move the cantilever crane to the front end of the previous section of the load-bearing structure and repeat steps one through three until the entire system is dismantled.

[0027] The system's components are all designed to standard dimensions, enabling prefabricated construction. Installation follows the principle of "bottom to top," while disassembly follows the principle of "top to bottom." The load-bearing system must meet overall and local requirements for strength, stiffness, deformation, and stability. Each component of the load-bearing system must be designed to standard dimensions, using socket or bolt connections for easy installation, disassembly, and reuse.

[0028] This prefabricated cliff and steep slope transport channel system can replace excavated access roads, eliminating the need for transport vehicles to navigate steep slopes and preventing vehicle rollover accidents, thus improving safety. Furthermore, its installation and construction cause minimal disturbance to the surrounding environment, enabling timely ecological restoration and meeting green construction requirements. It can also be self-loading and unloading using a crane. All components are designed with standard dimensions, achieving prefabricated construction and allowing for the repeated reuse of materials, saving costs. Attached Figure Description

A derrick crane and transport trolleys were then installed on the longitudinal beams. The derrick crane and transport trolleys were used to transport and unload materials for the installation of the pedestrian walkway, guardrails, and concrete pump pipes, completing the first segment's structural installation. Using the transport and loading system, steel, concrete, and other construction materials were transported to the end of the walkway, and steps one through three were repeated until the entire system was installed. During dismantling, the derrick crane and transport trolleys were used to dismantle the final segment's pedestrian walkway, guardrails, concrete pump pipes, and other structures, and transport them back to the starting point. The transport trolleys were moved to the penultimate segment, and the derrick crane was fixed to the end of the penultimate segment's load-bearing structure. The final segment's main load-bearing structure was then dismantled. The final section of the main load-bearing structure is dismantled from top to bottom. Transport trolleys are used to transport the dismantled longitudinal beams, diagonal braces, cross beams, transverse connecting rods, and columns to the foot of the mountain.

After the final section of the load-bearing structure is dismantled, the derrick crane is moved and secured to the end of the previous section. This process is repeated until the entire system is dismantled.

[0048] The specific installation and construction process is as follows: First, construct the main load-bearing structure. Drill holes using a soil drilling rig, analyze geological conditions, pour the foundation base 11, then drive in anchor piles of anchor bolt assembly 12, then install columns 2 and transverse connections 22, and erect crossbeams 3, longitudinal beams 4 and diagonal braces 21 to form the first segment of the main load-bearing structure.

[0049] The second step is to install the boom crane 9 and the transport trolley 7 on the longitudinal beam 4.

[0050] The third step is the installation of other structures. Using a derrick crane 9 and a transport trolley 7, materials are transported and unloaded to install the pedestrian walkway 5, guardrails 6, and concrete pump pipes 8, completing the installation of the first segment of the structure.

[0051] The fourth step involves using a transportation and loading / unloading system to transport construction materials such as steel and concrete to the end of the installed segments. This process is repeated from the first to the third step until the entire system is installed.

[0052] The specific dismantling process is as follows: First, dismantle the remaining structures of the final segment. Use the derrick crane 9 and transport trolley 7 to dismantle and transport the pedestrian walkway 5, guardrail 6, concrete pump pipe 8, and other structures of the final segment to the starting point.

[0053] The second step is to move the transport trolley 7 to the penultimate section and fix the boom crane 9 to the end of the penultimate section's load-bearing structure.
