Description
Technical Field
The utility model belongs to the technical field of the bridge jacking construction, especially, relate to a steel case lip block is used in bridge jacking construction.
Background
The bridge jacking construction is that the integral hydraulic synchronous lifting scheme is adopted, namely the original cast-in-place pile is used for bearing, the connection among an original bridge deck pavement layer, a handrail, a sidewalk and beam plates and the like is not damaged, a hydraulic jacking device is firstly used for integrally jacking the upper structure of the bridge, then stand columns below piers and a table cap beam are cut off, the hydraulic jacking device is operated, the bridge is integrally lifted to the designed height, and finally long stand column steel bars are connected to vertically mold and water second-stage concrete. The bridge superstructure refers to a general term of a part spanning a bridge opening above a bridge support (above a non-hinged arch camber line or a frame main beam bottom line).
Nowadays, the adopted hydraulic jacking device is generally a hydraulic jack. When the hydraulic jacking device is adopted to jack the bridge superstructure, the stroke of the jack is limited, the bridge superstructure needs to be jacked for many times from first to last, one or more supporting cushion blocks need to be supported below the jack after the jack finishes jacking every time, and therefore the laying height of the jack can be adjusted to enable the jack to meet the requirement of jacking next time. After the jack finishes jacking each time, the total thickness of the supporting cushion blocks supported below the jack is consistent with the jacking height of the jack last time, so that the number of the supporting cushion blocks required in the jacking process is large, and the function of the supporting cushion blocks in the jacking process is very important. In order to reduce the dead weight and facilitate installation, the thickness of the adopted support cushion blocks is generally 10 cm-20 cm, so that in the process of jacking the upper structure of the bridge, the number of the support cushion blocks supported below the jack is large, and a plurality of support cushion blocks are distributed from bottom to top to form a temporary vertical support structure.
At present, most of the supporting pads are steel pads or steel base plates. During actual construction, the existing supporting cushion block has the following problems: firstly, poor support stability: the supporting cushion blocks are easy to shift or incline, particularly when the number of the supporting cushion blocks supported below the jack is large, the vertical supporting structure formed by assembling the plurality of supporting cushion blocks from bottom to top is poor in stability and easy to shift or incline, and the bridge superstructure has great potential safety hazard due to huge weight after being integrally lifted; secondly, the support strength is not sufficient: the adopted supporting cushion blocks are common steel cushion blocks or steel cushion plates, but the weight of the whole bridge superstructure is huge after jacking, the vertical supporting structure formed by assembling a plurality of supporting cushion blocks from bottom to top can not effectively solve the bearing problem after jacking of the bridge superstructure, the supporting strength is low, and the supporting effect is unreliable; thirdly, the on-site cushion installation difficulty is high, the position of the supporting cushion is not easy to control, in order to meet the supporting requirement, the weight of the adopted supporting cushion block is increased, and the construction space below the jack is limited, so that the on-site construction difficulty is high, and the supporting cushion block is difficult to accurately install in place; and the fourth and later period need to be dismantled, so that the workload is large.
In addition, when the hydraulic jacking device is adopted to jack the bridge superstructure, an auxiliary supporting structure is required to be synchronously adopted so as to facilitate jack underpinning. The jack underpins refer to that after the jack finishes jacking, an auxiliary supporting structure is needed to support the jacked bridge superstructure, the jack is controlled to retract and support cushion blocks below the jack, and then the bridge superstructure is jacked next time through the jack. The auxiliary supporting structure is also called a follow-up supporting structure, and the follow-up supporting structure has a follow-up supporting and protecting function in the jacking process.
At present, the auxiliary supporting structure who adopts is interim bearing structure, and follow-up demolising is accomplished in the jacking construction, and the lip block is also the essential component of auxiliary supporting structure. During actual construction, the auxiliary supporting structure can only adopt the supporting cushion blocks, a plurality of supporting cushion blocks are assembled from bottom to top to form the supporting structure, and the supporting structure can also be matched with the jack to support and cushion a plurality of supporting cushion blocks below the jack. At present, the supporting cushion block adopted by the auxiliary supporting structure also has the problems of poor supporting stability, insufficient supporting strength, unreliable supporting effect, incapability of meeting the bearing requirement after jacking of the upper structure of the bridge, large difficulty in on-site padding, difficulty in controlling the position of the supporting cushion, large later-period dismantling workload and the like.
