Description of drawings
Combine the description of its accompanying drawing through following embodiment, can further understand and use novel purpose, specific structural features and advantage in fact the utility model.Wherein, accompanying drawing is:
Fig. 1 be the utility model the jacking counterforce device install and use sketch map;
The specific embodiment
The utility model is jacking, the support system that is applied to building jacking engineering, especially a kind of bridge jacking engineering support system.Be to existing jacking, support system, comprise the significant improvement of making on the basis of shortcoming of bracing or strutting arrangement and method for supporting, have very important practice significance.
Below in conjunction with accompanying drawing and embodiment utility model is further specified:
The utility model provides a kind of bridge jacking device and raising method; Said bridge jacking device mainly comprise with PLC Hydraulic Synchronizing jacking control system, under the allotment of PLC Hydraulic Synchronizing jacking control system jack group and match with PLC Hydraulic Synchronizing jacking control system and to be combined into the jacking counterforce device 10 that jack 20 provides support.
Said jacking counterforce device 10 is for to plant reinforcing bar at original bridge bent cap (pier stud or abutment); Also can make concrete, jacking counterforce device or the metal construction suspension member basic as the jacking counter-force are installed in the jacking counterforce device that bent cap (pier stud or abutment) is gone up carrying jacking counter-force; The jacking counterforce device directly is installed or is used for fixing the jacking counterforce device at bridge bent cap (abutment or pier stud) end face in bridge bent cap (abutment or pier stud) side bar planting.Being installed in the last jacking counterforce device that carries the jacking counter-force of bent cap (pier stud or abutment) with the metal construction suspension member in the present embodiment serves as that the master carries out detailed description to jacking counterforce device 10:
The jacking counterforce device 10 of said metal construction suspension member can be any metal with strong hardness; For example steel, iron etc.; It is example that the utility model adopts the jacking counterforce device 10 of steel work suspension member; It is mounted on the abutment and carries the jacking counter-force, and its plate seam that is arranged in two adjacent plate-girders and is connected with bent cap (pier stud or abutment) through bar planting down.Certainly, this bracket is applicable to the jacking of different types of rridges, is not limited to slab and girder, and its position is also not only in the plate seam of adjacent plate-girder.Wherein, The similar bracket of jacking counterforce device 10 shapes; In the industry cycle also often be called as the jacking of bracket counter-force, be provided with in the middle and lower part of jacking counterforce device 10 one with the load plane 101 of the moulding of jacking counterforce device 10 one, be used for specifically carrying jack 20 and its.
In concrete jacking process, promptly be the raising method of main example with the bridge, wherein its jacking step is following:
