Description

Technical Field

[0001] This invention relates to a novel, quick-construction trestle bridge pier structure and construction method, belonging to the technical field of trestle bridge pier structure. Background Technology

[0002] A trestle bridge is a bridge built over rivers, lakes, or other bodies of water for pedestrian access. It consists of walkways constructed along the banks. Existing trestle bridge piers typically use steel or wooden pillars inserted directly into the water, with the bridge deck then fixed between these pillars. This method of construction is difficult, and the pillars are prone to subsidence and corrosion during use, leading to overall deformation. Furthermore, the piers are difficult to dismantle when the trestle is not in use. To address these shortcomings, this invention proposes a novel, quick-construction trestle bridge pier structure and construction method. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a new type of quick-construction trestle bridge pier structure and construction method to solve the existing problems.

[0007] A further improvement is that the upper and lower ends of the floating platform cavity are sealed and separated by a buoyancy water tank and an installation chamber. The buoyancy water tank is composed of a main water tank and two side water tanks. The water pump is fixed in the installation chamber, and the water inlet of the water pump extends to the lower end of the main water tank cavity through the water inlet pipe.

[0008] A further improvement is that a water inlet pipe is connected to the bottom of the main water tank, and a waterproof solenoid valve is connected to the water inlet pipe. A water passage hole is provided through the lower side between the main water tank and the side water tank.

[0009] A further improvement is that the first float group includes a driven transverse push group, and a swing arm assembly is engaged on the bottom surface of the left end of the driven transverse push group, and a support float connected to the air pump is provided at the lower end of the swing arm assembly. The first float group has the same structure as the second float group.

[0010] A further improvement is that the driven transverse push assembly includes a slide block, and a slide rod is transversely sleeved inside the slide block, and the cross-section of the slide rod is square-shaped, with a rack provided on the bottom surface of the left end of the slide rod.

A gear plate that meshes with a rack is arranged on the rear side of the upper end of the swing arm body. A rotating shaft is embedded on the front side of the upper end of the swing arm body. Both the swing arm body and the anchor cross arm are made of plastic.

[0012] A further improvement is that the positioning component includes a winch, and a first anchor and a second anchor are simultaneously wound on the left and right sides of the winch.

[0013] The first anchor includes a steel wire rope, on which a first guide wheel and a second guide wheel are spaced apart, and an anti-detachment pressure wheel is fitted above the second guide wheel. An anchor head is provided at the other end of the steel wire rope. The first anchor and the second anchor have the same structure.

[0016] A further improvement is that the length of each section of the trestle bridge deck is 3-5m.

[0017] A further improvement is that the control panel is also equipped with an external mobile power supply.

Then, install the trestle bridge deck frame on the top surface of the bridge frame.

[0020] S2: Then, a section of the trestle structure is lifted into the water by a crane. At this time, the supporting buoys are inflated and adjusted to a horizontal alignment, which provides stable support for the floating platform when it is towed. Then, it is pulled to the installation area by a tugboat, and then the bridge decks of the two adjacent trestle bridges are spliced ​​together.

[0021] S3: After all the trestle bridge deck frames are assembled, first adjust each supporting buoy to be fully submerged in the water at an angle, then fill the buoyancy tank with water to lower the floating platform, and adjust the height of the trestle bridge deck frame with reference to the water level sensor rod so that the two trestle bridge deck frames at the beginning and end are flush with the road surface.

[0022] S4: Then, the anchor heads on the first and second anchors are pulled away from the four sides of the floating pier by tugboat and placed in the water. Then, the anchor heads are pulled into the mud by the winch to position the pier structure in the water. Then, the operating platform is removed to complete the construction.

[0023] The beneficial effects of this invention are:

[0024] This invention provides a novel, rapid-construction trestle bridge pier structure and construction method. The pier structure, consisting of a pier assembly, two stabilizing platforms, and two positioning components, is designed to be integrated with the bridge frame and the underside of the trestle bridge deck, creating a rapid-construction trestle bridge pier structure. This pier structure floats directly on the water surface during construction. The buoyancy of the floating pier is enhanced through a hollow, sealed design of a buoyancy tank and installation chamber on the floating pier. The buoyancy adjustment of the floating pier is achieved through water inlet via a waterproof solenoid valve and water drainage via a pump. Stability is also provided. The platform assembly extends the range of auxiliary buoyancy adjustable support on both sides of the floating pier, making the floating pier float in the water and providing more stable support for the trestle bridge deck. Additionally, positioning components are provided to anchor the floating pier, preventing it from shifting in the water, thereby improving the stability of the trestle bridge deck. The final construction splicing and locking between the trestle bridge deck structures allows all the pier structures to be connected into a whole, effectively reducing the swaying of the trestle bridge deck. The pier structure of this invention does not require insertion into the mud for installation, and the main structural material is plastic, which has strong corrosion resistance. The pier is not easily deformed. It is easy and efficient to assemble and disassemble, and has a long service life. Attached Figure Description

[0032] The upper and lower ends of the floating platform 11 are sealed and separated by a buoyancy water tank and an installation chamber 113. The buoyancy water tank is composed of a main water tank 111 and two side water tanks 112. The water pump 13 is fixed in the installation chamber 113, and the water inlet of the water pump 13 extends to the lower end of the main water tank 111 through the water inlet pipe.

[0033] The bottom surface of the main water tank 111 is connected to a water inlet pipe 114, and a waterproof solenoid valve 115 is connected to the water inlet pipe 114. A water passage hole 116 is provided on the lower side between the main water tank 111 and the side water tank 112.

[0034] The first float group 22 includes a driven transverse push group 221, and a swing arm assembly 222 is engaged on the bottom surface of the left end of the driven transverse push group 221. A support float 223 connected to the air pump 24 is provided at the lower end of the swing arm assembly 222. The first float group 22 and the second float group 23 have the same structure.

The first anchor 32 and the second anchor 33 have the same structure.

[0038] Working principle:

[0039] The construction method is as follows:

[0040] S1: First, assemble the pier assembly 1, two stabilizing platform assemblies 2, two positioning components 3, and water level sensor rod 6 in advance to form the pier structure, and move the pier structure to the water's edge. Then, install the trestle bridge deck frame 5 on the top surface of the bridge frame 4.

[0041] It should be noted that after S1 is installed, the operating platform 7 will be electrically connected first, and the supporting floats 223 on the first float group 22 and the second float group 23 will be inflated by the air pump 24. The angle of the supporting floats 223 on the first float group 22 and the second float group 23 will also be adjusted so that the swing arm body 2221 on the supporting float 223 is horizontally aligned. This is to prevent the pier structure from completely tilting in the water due to the stress on one side of the trestle bridge deck 5 when it is towed in the water.

[0042] S2: Then, a section of the trestle structure is lifted into the water by a crane. At this time, the supporting buoy 223 is inflated and adjusted to a horizontal alignment state, which provides stable support for the floating platform 11 during towing. Then, it is pulled to the installation area by a tugboat, and then the two adjacent trestle bridge deck frames 5 are spliced ​​together.

[0043] It should be noted that before the entire pier structure is lowered into the water, the operating platform 7 must be removed first. This is to prevent the floating platform 11 from tilting at a small angle during towing, which could cause water damage to the operating platform 7. In addition, the splicing of the two adjacent pier deck frames 5 is only a simple fixation at this stage, and is not completely spliced ​​and locked. This way, when adjusting the buoyancy height of the floating platform 11 later, the pier deck frames 5 can move between each other, and the individual floating platforms 11 will not be unable to be adjusted one by one.

[0044] S3: After all the trestle bridge deck frames 5 are assembled, first adjust each supporting buoy 223 to be fully submerged in the water at an angle, then fill the buoyancy tank with water to lower the floating platform 11, and adjust the height of the trestle bridge deck frames 5 with reference to the water level sensor rod 6 so that the two trestle bridge deck frames 5 at the beginning and end can be flush with the road surface.

[0045] It should be noted that the floating pier 11 needs to be sunk to a certain water level. The optimal water level is the lower edge of the horizontal platform 12. This way, the angle required for the supporting buoy 223 to be submerged in the water can be smaller, maximizing the support area of ​​the pier structure formed by the supporting buoy 223 and the floating pier 11 in the water. In addition, through the advance height measurement design of the bridge frame 4, the main support height for the trestle bridge deck frame 5 to be flush with the road surface is on the bridge frame 4, while the pier structure only plays a minor adjustment role.

[0046] In addition, the angle adjustment of the first float group 22 and the second float group 23 is achieved by bidirectional extension and retraction of the bidirectional telescopic device 21, and synchronous left and right push and pull of the slide rod 2212 on the slide block 2211. Through the meshing of the rack 2213 and the gear plate 2223, the swing arm body 2221 swings up and down on the rotating shaft 2224, thereby realizing the adjustment of the height of the supporting float 223.

[0047] S4: Then, by using a tugboat to pull the anchor heads 325 on the first anchor 32 and the second anchor 33 to the four sides away from the floating pier 11 and put them into the water, the anchor heads 325 are pulled into the mud by the winch 31 to position the pier structure in the water. Then, the operating platform 7 is removed to complete the construction.

[0048] When the floating platform 11 is in use, if the trestle bridge deck 5 sways significantly from side to side while walking, the supporting float 223 can be inflated again by the air pump 24 to increase its volume and increase the buoyancy on both sides of the floating platform 11. This will reduce the swaying of the trestle bridge deck 5. In addition, after the first anchor 32 and the second anchor 33 are fixed, the water in the main water tank 111 and the side water tank 112 can be pumped out by the water pump 13 to increase the upward buoyancy of the floating platform 11 in the water, which can reduce the descent of the floating platform 11 when people walk on the trestle bridge deck 5.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
