The fast beam descent lifting and supporting mechanism of the bridge synchronous lifting technology is characterized by comprising a plurality of secondary columns and primary columns, wherein the secondary columns and the primary columns are of steel column butt joint structures. The secondary columns and the primary columns are distributed for forming a bridge bearing body, and synchronous lifting devices are arranged on the upper portions of the primary columns. The fast beam descent lifting and supporting mechanism of the bridge synchronous lifting technology is reasonable in structural design, fast and safe to use, convenient to install and low in use cost, fast and stably enabling a whole bridge to descend stably and gradually, lowering the labor intensity requirement of construction, and reducing potential safety hazards of crushing equipment and sites.
Description
Technical field
The utility model belongs in the integral bridge displacement treats the carrying disposal facility of disposing old bridge, is specifically related to a kind of fast prompt drop back support mechanism of processing position of old bridge after packing being down to based on the bridge synchronous jacking technology.
Background technology
Along with the application widely of China's overhead road bridge construction, the timely reconstruction after being removed 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 the polytype traffic aisle, can't carry out on-the-spot orcible entry or fragmentation post processing, because existing environment and place can't meet long-time construction requirement, the while builds temporarily or the construction of prefabricated property bridge also can't meet place and on-the-spot broken construction.And, carry out the split cutting of bridge according to the requirement that bridge is packed car after, pack car with bridge and be transported to appointed place and torn down.But the bridge acknowledgement of consignment of carrying Liang Cheshang on the back is highly higher, bridge need to be carried out to steady decrease at the orcible entry scene to the orcible entry height, can exist to tilt and the potential safety hazard such as topple but there is the greater weight bridge in the reduction process as can not stablize control, need to carry out the comparatively stable beam operation of falling.
The utility model content
The utility model provides a kind of reasonable in design, has used the fast prompt drop back support mechanism of the bridge synchronous jacking technology of quick and safe, it is easy for installation, use cost is low, can stablize the progressively reduction that realizes that fast integral bridge is stable, 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 back support mechanism of bridge synchronous jacking technology, it is characterized in that described top bracing mechanism 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 the 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 described sub-post is arranged on the both sides of female post.
In one embodiment, described sub-post and female intercolumniation, respectively by the described bridge of joist pushing tow, connect the shaped steel tie-beam are set between described sub-post and female post.
In one embodiment, described synchronous jacking device is hydraulic jack, between this hydraulic jack and joist, connects to arrange and corresponding with female column top.
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 master controller.
In another embodiment, sub-post and female column top also are 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.
The fast prompt drop back support mechanism of this bridge synchronous jacking technology adopts the sub-post of multistage steel column butt joint and the carrying main body that female post forms bridge, by the synchronous jacking device arranged on cushion block and female post, completes alternately descending of sub-post and female post carrying height.In concrete application, 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 descends of two ends, bridge left and right.Each end adopts a joist to realize the whole uniform distribution of load-bearing.
The beneficial effects of the utility model are, the fast prompt drop back support mechanism reasonable in design of this bridge synchronous jacking technology, use quick and safe, it is easy for installation, use cost is low, can stablize the progressively reduction that realizes that fast integral bridge is stable, 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.
The 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, the fast prompt drop back support mechanism of this bridge synchronous jacking technology comprises sub-post 20 and female post 30 of multi-segmental steel column butt joint structure, and described sub-post and female post distribute to arrange and form the 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 and female column combination are set.Two groups of corresponding sub-posts that arrange and female column combination, respectively by the described bridge 10 of joist 40 pushing tow, connect shaped steel tie-beam 22 are set between described every group of sub-post and female column combination.Synchronous jacking device 31 is hydraulic jack, between this hydraulic jack 31 and joist 40, connects to arrange and corresponding with female post 30 tops.In concrete application, the 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 also are 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, carry out the decline of bridge 10 by the synchronous jacking device 31 arranged on female post 30, as shown in Figure 2, sub-post 20 becomes the bearing support point, after now extracting the cushion block 21 on female post 30 out, drive synchronous jacking device to descend, 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 descend, make the sub-post 20 reduced again accept bridge weight.Progressively can realize successively the steady fast reducing of integral body of bridge.
