Description

TECHNICAL FIELD

[0001] The utility model relates to bridge pushing construction technical field, concretely relates to a guide beam pier device for bridge pushing construction. BACKGROUND

[0002] The pushing method is a common bridge construction method for building across busy waterway, highway and railway, when the large-span bridge pushing construction, generally through the guide beam mode to effectively reduce the negative bending moment peak value at the front end support point of the pushing main beam, but due to the deadweight effect, the guide beam is in the cantilever state before the pier, and the front end will produce larger sag before the pier, so that the front end bottom surface height of the guide beam is lower than the height of the cushion block on the front end support pier, and the front end support pier cannot be mounted.

[0003] At present, in order to solve the guide beam pier difficulty in the bridge pushing construction, the main methods are to install cable tower on the beam body to lift the beam end, to use circular arc guide beam and ladder type guide beam. Among them, the ladder type guide beam needs manual copying cushion to cooperate to complete the guide beam pier.

[0004] In the traditional ladder type guide beam with manual copying cushion pier method, when the guide beam sag is large, it needs to copy the cushion repeatedly, consumes a lot of labor cost and construction period, and has the following defects: 1, manual copying cushion work needs to stack cushion on temporary support and three-way top in turn, because the cushion is small in size to adapt to manpower, the help of each time to jacking is limited. 2, manual copying cushion needs many workers to work on the pier for a long time, the working environment is relatively poor, and the safety hidden danger is increased. 3, copying cushion work is an intermediate process of bridge pushing construction, workers need to carry the cushion to the jack and temporary support before the guide beam pier, and need to remove the cushion placed after the pier, and constantly circulate this process, causing a lot of resource waste.

[0005] According to the search, the announcement number CN117144816A discloses a stepped guide beam, a pushing device and a guide beam automatic piling method. The method realizes the automatic piling of the guide beam by setting two groups of independently working three-way jacks and a stepped guide beam with a specific gradient, can save the intermediate step of manual cushioning: after each jacking of the jack, a layer of cushion block is stacked on the temporary support and the jack surface in turn, and after the total height of the cushion block can make the next step piling, the cushion block is removed and the work is repeated. The method limits the step height and length of the guide beam, so that the guide beam is jacked and piled step by step during the forward pushing process, greatly saving the labor cost and construction period. The method also has the following disadvantages: 1. The front nose of the guide beam needs to be provided with multiple steps, which is relatively complex in structure and manufacturing, increasing the difficulty and cost of manufacturing the guide beam; 2. The two groups of three-way jacks need to be alternately jacked during the piling process, and the jacking of one group of three-way jacks needs to be manually switched to the work of the other group. The switching needs to terminate the forward pushing process of the bridge to be completed, and the forward pushing process can continue after the switching is completed. The height of the cushion block needs to be manually replaced after each jacking; 3. After the jacking of one group of three-way jacks is completed, the three-way jacks need to be reset to the initial position, and the resetting process needs to be manually completed. Therefore, it is particularly important to improve the existing guide beam piling device and design a new guide beam piling device for bridge pushing construction to solve the above technical defects and improve the practicality of the overall guide beam piling device.
