[0020] The floating pier 11 has sealed partitions at both ends, with 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 end of the water pump 13 extends to the lower end of the main water tank 111 through an inlet pipe.

[0021] The bottom surface of the main water tank 111 is connected to a water inlet pipe 114 , and the water inlet pipe 114 is connected to a waterproof solenoid valve 115 . A water hole 116 is provided on the lower side between the main water tank 111 and the side water tank 112 .

[0022] The first float group 22 includes a driven transverse thrust group 221, and a swing arm assembly 222 is engaged on the bottom surface of the left end of the driven transverse thrust group 221, and a supporting 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.

[0023] The driven transverse thrust group 221 includes a slide seat 2211 , and a slide rod 2212 is transversely sleeved in the slide seat 2211 . The cross section of the slide rod 2212 is square-shaped, and a rack 2213 is disposed on the bottom surface of the left end of the slide rod 2212 .

[0024] The swing arm assembly 222 includes a swing arm body 2221, and an anchor cross arm 2222 is laterally arranged on the left side of the swing arm body 2221, and a gear plate 2223 meshing with the rack 2213 is arranged on the rear side of the upper end of the swing arm body 2221, and a rotating shaft 2234 is embedded on the front side of the upper end of the swing arm body 2221.

[0025] The positioning assembly 3 includes a winch 31, and the first anchor 32 and the second anchor 33 are synchronously wound on the left and right sides of the winch 31. The first anchor 32 includes a steel wire rope 321, and the steel wire rope 321 is alternately penetrated by a first guide wheel 322 and a second guide wheel 323, and an anti-slip pressure wheel 324 is fitted in the gap above the second guide wheel 323. An anchor head 325 is provided at the other end of the steel wire rope 321. The first anchor 32 and the second anchor 33 have the same structure.

[0026] Working principle: The construction method is as follows: S1: First, assemble the bridge pier assembly 1, two stabilizing platform assemblies 2, two positioning components 3, and a water level sensor rod 6 in advance to form a pier structure, and move the pier structure to the waterside, and then install the trestle bridge deck frame 5 on the top surface of the bridge frame 4; It should be noted that after S1 is installed, it will be electrically connected to the operating table 7 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 angles of the supporting floats 223 on the first float group 22 and the second float group 23 will also be adjusted to make the swing arm body 2221 on the supporting float 223 in a horizontally aligned state. This is to prevent the pier structure from completely tipping over in the water due to the unilateral stress on the pier deck frame 5 when the pier structure is subsequently towed in the water.

[0027] S2: Then, a section of the trestle overall structure is hoisted into the water by a hoisting machine. At this time, the supporting buoy 223 has been inflated and adjusted to a horizontal alignment state, which provides stable support for the floating pier 11 during towing. Then, the tugboat is used to pull it to the installation area, and then the two adjacent trestle deck frames 5 are spliced; It should be noted that before the entire structure of the pier is hoisted into the water, the operating platform 7 must be folded down first. This is to prevent the floating pier 11 from tilting at a small angle when being towed, which would cause water ingress and damage to the operating platform 7. In addition, the splicing of the two adjacent pier deck frames 5 is simply fixed at this stage and is not completely spliced ​​and locked. In this way, when the buoyancy height of the floating pier 11 is adjusted later, the pier deck frames 5 can move between each other, and a single floating pier 11 will not be unable to be adjusted in sequence.

[0028] S3: After all the trestle bridge deck frames 5 are spliced, first adjust each supporting float 223 to completely enter the water obliquely, then fill the buoyancy water tank with water to lower the floating pier 11, and refer to the water level sensor rod 6 to adjust the height of the trestle bridge deck frame 5 so that the first and last trestle bridge deck frames 5 can be flush with the road surface; It should be noted that the floating pier 11 needs to sink to a certain water level, and the optimal water level is to the lower edge of the horizontal platform 12, so that the oblique angle required for the support float 223 to complete the immersion in the water can be smaller, so that the support area range of the pier structure formed by the support float 223 and the floating pier 11 in the water can be maximized. In addition, through the advance height measurement design of the bridge frame 4, the main support height of the trestle bridge deck frame 5 and the road surface is made on the bridge frame 4, and the pier structure only plays a fine-tuning role; In addition, the angle adjustment of the first float group 22 and the second float group 23 is achieved by the two-way telescopic device 21 extending in both directions, and the left and right push-pull slide rods 2212 slide on the slide seat 2211 synchronously, and the rack 2213 is engaged with the gear plate 2223, so that the swing arm body 2221 swings up and down on the rotating shaft 2234, thereby achieving the height adjustment of the supporting float 223.

[0029] S4: Then, the anchor heads 325 on the first anchor 32 and the second anchor 33 are pulled to the four sides away from the floating pier 11 by a tugboat and put into the water. Then, the anchor heads 325 are reeled in by the winch 31 so that they are tightened and inserted into the soil to position the pier structure in the water. Then, the operating platform 7 is removed to complete the construction.

[0030] When the floating pier 11 is in use, if the trestle deck frame 5 shakes left and right significantly when walking, the supporting float 223 can be inflated again by the air pump 24 to increase the volume of the supporting float 223 and increase the buoyancy on the left and right sides of the floating pier 11, thereby reducing the left and right shaking of the trestle deck frame 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, thereby increasing the upward buoyancy force of the floating pier 11 in the water, which can reduce the degree of descent of the floating pier 11 when people walk on the trestle deck frame 5.
