AI Technical Summary
Existing methods for constructing arch bridges across rivers are costly and time-consuming under navigable river conditions. These methods are also cumbersome and limited by high and low tide levels, which affects construction efficiency.
A dual-boat transport and installation device for arch bridges is adopted, including a base, a turntable, multi-layer rectangular blocks, and hydraulic jacks. The height of the blocks is adjusted by the hydraulic jacks to support and lift the arch bridge to the bridge position, simplifying the construction process and improving stability.
It reduced construction costs, improved construction efficiency, simplified construction procedures, and avoided construction time constraints caused by changes in tide levels.

Description
TECHNICAL FIELD
[0001] The utility model belongs to bridge construction technical field relates to a whole installation construction of arch bridge, concretely relates to a kind of arch bridge double-ship transportation installation equipment. BACKGROUND
[0002] When the arch bridge across the river is constructed, in order to avoid affecting the river navigation during construction, the arch bridge is usually assembled into a whole on the bank, and the arch bridge is floated to the bridge site for installation by double ships. When the arch bridge is transported to the bridge site for installation, one method is to erect two lifting towers in the river to lift the arch bridge onto the pier, which has high construction cost and long construction time. Another method is to inject or discharge ballast water in the ship cabin, and adjust the height of the ship by using the high and low tide water level, so as to drop the arch bridge onto the pier, which has complicated process and long construction time. SUMMARY
[0003] The utility model aims at the above problems, provides a kind of arch bridge double-ship transportation jacking equipment to reduce construction cost and improve construction efficiency.
[0004] The technical scheme of the utility model is as follows:
[0005] An arch bridge double-ship transportation installation equipment is characterized by comprising a base, a turntable is arranged on the top surface of the base, multiple layers of upper and lower stacked cushion blocks are arranged on the turntable, the plane of each cushion block is rectangular, a hydraulic jack is arranged at each of the four corners of the upper and lower adjacent two cushion blocks, a cushion plate is arranged on the top surface of the uppermost layer of cushion blocks, and a temporary support is arranged on the cushion plate; a control console for uniformly controlling the hydraulic jacks is arranged on one side of the base.
[0006] The utility model has high support and bearing capacity, and can flexibly adjust the height. The arch bridge whole transportation installation can simplify the construction process, save construction cost and improve construction efficiency. DRAWING DESCRIPTION
[0007] Figure 1 is the whole structure schematic diagram of the utility model;
[0008] Figure 2 is the installation structure schematic diagram of jack between upper and lower cushion blocks of the utility model;
[0009] Figure 3 is the use state schematic diagram of the utility model. DETAILED DESCRIPTION
[0010] As Figure 1 , Figure 2As shown, this utility model includes a base 1, a turntable 2 on the top surface of the base, multiple layers of stacked pads 3 on the turntable, each pad having a rectangular plane, a hydraulic jack 4 at each of the four corners of two adjacent pads, a pad plate 5 on the top surface of the top pad, and a temporary support 6 on the pad plate; a control console 7 for unified control of each hydraulic jack is provided on one side of the base.
[0011] In a specific implementation of this utility model, in order to ensure the stability of the hydraulic jack position, a jack slot 8 is provided at each of the four corners of the top and bottom surfaces of each pad block 3. The bottom of the jack 4 between the upper and lower pad blocks is locked in the slot 8 on the top surface of the lower pad block, and the top of the jack 4 is locked in the slot 8 on the bottom surface of the upper pad block.
[0012] In a specific implementation of this utility model, in order to reduce the weight of the pad block 3, each pad block can be set as a rectangular frame structure, which is welded from 4 steel sections. The jack slots 8 on the top and bottom surfaces of each pad block are respectively made of round steel cylinders, which are welded to the upper and lower flange plates of the steel section.
[0013] To further reduce the weight of the pad, at least one weight-reducing hole 9 can be opened on the web of each steel segment of the pad 3.
[0014] like Figure 3 As shown, when using two boats to transport the arch bridge, a utility model arch bridge installation device is fixedly installed on each transport boat 10, and the two ends of the arch bridge 11 are supported on the temporary supports on the top of the two devices and temporarily fixed. During the transportation process, all jacks are in a retracted state to lower the center of gravity of the arch bridge and improve its stability.
[0015] When the arch bridge 11 is transported to the bridge site, the jacks 4 between each layer of pad blocks 3 are activated simultaneously to raise the arch bridge to a height above the pier 12. Then, the attitude of the transport ship is adjusted so that the plane position of the arch bridge meets the design requirements and the transport ship is anchored. Finally, the arch bridge is lowered onto the pier top support by controlling the retraction of the jacks, thus completing the installation of the arch bridge.
[0016] The turntable of this device can be set to both active and locked states. Generally, during the transportation of the arch bridge, the turntable is in the locked state to ensure reliable support for the arch bridge; when adjusting the ship's attitude during the installation of the arch bridge, the turntable can be set to the active state to minimize the generation of secondary internal forces in the arch bridge during the ship's attitude adjustment, thus avoiding bridge deformation.
