Technical Field
The invention relates to bridge support replacement, in particular to a construction auxiliary device for a beam bottom wedge block and a using method thereof.
Background
The bridge support has the functions of smoothly and safely transferring the load of the upper structure of the bridge to the bridge abutment, ensuring the free deformation of the upper structure under the action of factors such as load, temperature change, concrete shrinkage and creep and the like, and protecting the beam body and the abutment from being damaged. The bearing diseases are found to be very common in the daily inspection, regular inspection and special inspection processes of the bridge. The plate-type rubber support of the medium-small span bridge has the characteristics of prominent and typical diseases, and is particularly characterized by support void, local pressure bearing, overlarge shear deformation, support aging, support cushion stone and beam bottom wedge-shaped block cracking, breakage and the like. Once the support has the above-mentioned diseases, the functions of transferring the load of the upper structure and following the deformation of the beam body gradually decline and even lose, which directly affects the stress safety of the bridge structure. Therefore, reasonable and effective measures are adopted to timely replace the damaged support under the condition of not causing damage to the bridge structure so as to recover the original function of the damaged support, and the operation safety of the bridge is ensured. Therefore, the bridge support replacing technology is developed.
The existing bridge support replacing method comprises a sleeper full-cloth type support method, a saddle type support method, a steel carrying pole beam method and a direct jacking method.
