The rapid beam descending support system based on the bridge synchronous jacking technology has the advantages that the structural design is reasonable, the application is rapid and safe, the mounting is convenient, the use cost is low, the situation that a bridge is integrally lowered stably and gradually can be stably and rapidly realized, and the potential safety hazard caused by labor intensity requirement for construction to crushing equipment and sites is relieved.
Description
Technical field
The utility model belongs in integral bridge displacement treats the carrying disposal facility of disposing old bridge, is specifically related to a kind of fast prompt drop beam support system based on bridge synchronous jacking technology of processing position that old bridge after packing is down to.
Background technology
Along with the application widely of China's overhead road bridge construction, the timely reconstruction after removing for the bridge that has disease or breakage becomes the important subject of construction.Bridge for central core of circulation or strategic road is removed, the intersection area that particularly relates to polytype traffic aisle, cannot carry out on-the-spot orcible entry or fragmentation post processing, because existing environment and place cannot meet long-time construction requirement, the while builds temporarily or the construction of prefabricated property bridge also cannot meet place and on-the-spot broken construction.And according to the requirement that bridge is packed car, carry out after the split cutting of bridge, with bridge, pack car and be transported to appointed place and tear down.But the bridge acknowledgement of consignment of carrying Liang Cheshang on the back is highly higher, at orcible entry scene, bridge need to be carried out to steady decrease to orcible entry height, but there is greater weight bridge in reduction process as can not stablize control, can exist to tilt and the potential safety hazard such as topple, need to carry out the comparatively stable beam operation of falling.
Utility model content
The utility model provides a kind of reasonable in design, has used the fast prompt drop beam support system based on bridge synchronous jacking technology of quick and safe, it is easy for installation, use cost is low, can stablize and realize fast the stable progressively reduction of integral bridge, the labour intensity that alleviates construction requires crushing appliance and on-the-spot potential safety hazard.
The technical scheme that the utility model adopts is as follows:
A kind of fast prompt drop beam support system based on bridge synchronous jacking technology, it is characterized in that described support system comprises sub-post and female post of multi-segmental steel column butt joint structure, described sub-post and female post distribute to arrange and form bridge bearing body, and described female post top arranges synchronous jacking device.
In the specific embodiment, described sub-post and female post are that a plurality of distributions arrange structure, and the two ends under described bridge distribute two groups of corresponding sub-posts and female column combination are set.
In one embodiment, described two groups of corresponding sub-posts that arrange and female column combination, respectively by bridge described in joist pushing tow, connect shaped steel tie-beam are set between described every group of sub-post and female column combination.
In one embodiment, described synchronous jacking device is hydraulic jack, connects to arrange and corresponding with female column top between this hydraulic jack and joist.
In one embodiment, described synchronous jacking device connection arranges a master controller and controls, and each synchronous jacking device all arranges displacement transducer and hydrostatic sensor, and each synchronous jacking device is realized the Collaborative Control of jacking and decline by middle controller.
In another embodiment, described sub-post and female column top are also provided with cushion block, and the height of described cushion block is less than the height of every sections steel column in described multi-segmental steel column.
Should the fast prompt drop beam support system based on bridge synchronous jacking technology adopt the sub-post of multistage steel column butt joint and the carrying main body that female post forms bridge, by the synchronous jacking device arranging on cushion block and female post, complete alternately declining of sub-post and female post carrying height.Sub-post and female post and adopt minute two groups of modes that arrange, the two ends, left and right of accepting respectively bridge, the adjustment that synchronously declines of two ends, bridge left and right.Every one end adopts a joist to realize the whole uniform distribution of load-bearing.
The beneficial effects of the utility model are, be somebody's turn to do fast prompt drop beam support system reasonable in design, use quick and safe based on bridge synchronous jacking technology, it is easy for installation, use cost is low, can stablize and realize fast the stable progressively reduction of integral bridge, the labour intensity that alleviates construction requires crushing appliance and on-the-spot potential safety hazard.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is a status architecture schematic diagram of the utility model specific embodiment;
Fig. 2 is another status architecture schematic diagram of the utility model specific embodiment;
Fig. 3 is the another status architecture schematic diagram of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1, should comprise based on the fast prompt drop beam support system of bridge synchronous jacking technology sub-post 20 and female post 30 of multi-segmental steel column butt joint structure, described sub-post 20 and female post 30 distribute to arrange and form bridge bearing body, and described female post 30 tops arrange synchronous jacking device 31.Sub-post 20 and female post 30 arrange structure for a plurality of distributions, and the two ends under described bridge distribute two groups of corresponding sub-posts 20 and 30 combinations of female post are set.Two groups of corresponding sub-posts 20 that arrange and 30 combinations of female post, respectively by bridge 10 described in joist 40 pushing tows, connect shaped steel tie-beam 22 are set between described every group of sub-post 20 and 30 combinations of female post.Synchronous jacking device 31 is hydraulic jack, connects to arrange and corresponding with female post 30 tops between this hydraulic jack and joist 40.In concrete application, synchronous jacking device connection arranges a master controller and controls, and each synchronous jacking device all arranges displacement transducer and hydrostatic sensor, and each synchronous jacking device is realized the Collaborative Control of jacking and decline by middle controller.Yu Zizhu and female column top are also provided with cushion block 21, and the height of described cushion block 21 is less than the height of every sections steel column in described multi-segmental steel column.
As shown in Figure 1, upper end at sub-post 20 and female post 30 all arranges cushion block 21, by the synchronous jacking device 31 arranging on female post 30, carry out the decline of bridge 10, as shown in Figure 2, sub-post 20 becomes bearing support point, now extract out after the cushion block on female post 30, drive synchronous jacking device 31 to decline, make female post 30 again accept bridge weight;
As shown in Figure 3, again by synchronous jacking device 31, carry out the pushing tow of bridge 10, and extract the cushion block 21 on sub-post 20 out or reduce the joint number of sub-post, and drive synchronous jacking device 31 to decline, make the sub-post 20 reducing again accept bridge weight.Progressively can realize successively the steady fast reducing of integral body of bridge.
