Like an aircraft carrier, it can only ride on the ocean, not in the pond. In the process of bridge support replacement, it is necessary to carry out a comprehensive inspection on the bridge according to the foundation, pier, main beam, bridge deck system and affiliated works one by one, and make good records and photos. For the foundation, pier existing disease should be treated first, and then treatment of the main beam. If the support needs to be replaced, it shall be decided whether the bridge deck system and auxiliary works should be reserved or completely removed according to the specific situation of the bridge deck system and auxiliary works; If it needs to be retained, the longitudinal connection of the bridge holes should be lifted in advance, and the bearing replacement construction should be carried out finally. In traditional construction methods, jacking supports are required to be set up on available extended foundations or caps, but the jacking point should be as close to the original fulcrum as possible. If there is no expanded foundation or cap that can be used, it is necessary to re-cast the temporary bearing foundation, and then set up the jacking support to implement the operation. This situation occurs in the pier or solid pier structure of the column pile butt.

Deep water foundations are more difficult. According to the construction experience and actual situation, under the condition that the pier structure has no disease, jacking can be carried out directly on the top surface of the cover beam and under the flange plate of the hollow slab beam, but the height of the jack is not more than 3cm. For this purpose, "ultra-low height air bag jack" can be used to implement. The operation platform is set up at the pier position, and the bracket is set up for the waterless area, and ordinary scaffold steel pipe and fastener can be connected; For piers in the water, a boat is used to build brackets. The strength and stability of the support should meet the requirements of operation safety. After the completion of the support, the pier support for a comprehensive inspection, and do a good record and number. According to the inspection situation, determine the replacement parts, and number of bridge spans, according to the traffic run "green condition, make best bearing replacement plan. Deal with jack put place to clean up before operation, to facilitate the jack and the plate was stable. At the same time determine the plate used by jack, plate USES the steel plate (10 mm) thick.

The size shall not be less than 14cm×14cm, and it shall be placed in front of the corresponding plate bearing, and a certain number of thin steel plates or wedge-shaped steel plates shall be prepared to facilitate the over-cushion wedging in the process of plate beam lifting. Load test should be carried out on air bag jacks, air pipes and gates before use to verify the effectiveness of each device. 3.4 Test roof support frame, operating platform and jack can be tested after installation. (1) The layout and number of temperature measuring holes shall be drawn. Generally speaking, the process of bridge reinforcement: steel plate production ~ concrete surface and steel plate surface treatment ~ dispensing glue ~ gluing ~ drilling, riveting fixed steel plate ~ inspection. Exists in our life is the most important projects, the construction of a unified maintainers must first pay attention to regular maintenance process, thus effectively guarantee the safety protection of the build system used in unity, first of all take the current various professional departments on the bridge bearing replacement, the project is in smooth type to pay attention to the important factors in the use, First of all, it is necessary to attract our common attention.

So today we will learn about the problems that should be paid attention to in daily maintenance of the bridge bearing replacement. Bridge bearing replacement in each overhaul link should pay attention to the related issues, this aspect should be unified first cause we are all common concerns, and also can effectively improve the operating projects in the future development of substantial present sex, so today in the following we will come together to learn about, about the bridge bearing replacement in the daily maintenance and repair work should pay attention to the related issues. Different jacking methods should be adopted for different types of Bridges. For the section form composed of T beam or I-beam, generally can be placed under the beam body plate directly with the method of jacking up; But when lifting the core plate and box girder, it is necessary to pay attention to the lifting part, avoid directly lifting the bottom of the beam body, but easy to choose in the ribs and box girder web part, to prevent the damage to the beam body. Due to the influence of side beam itself weight and bridge deck auxiliary facilities (such as guardrail, connector).
