Description

Technical Field

[0001] The present invention relates to the technical field of temporary bridge support foundations, and in particular to an intelligent installation device and a construction method for temporary bridge support foundations. Background Art

[0002] A bridge generally refers to a structural structure built across rivers, lakes, and seas to allow vehicles, pedestrians, etc. to pass smoothly. In order to adapt to the rapid development of modern transportation industry, bridges are also extended to refer to buildings that are built to cross mountain streams, poor geological conditions or meet other transportation needs to make travel more convenient. Among them, the main beam refers to the beam in the superstructure that supports various loads and transmits them to piers and abutments. It is one of the main load-bearing structures of the bridge. In the construction of the main beam of a bridge, for a river-crossing bridge, when the river channel is an important transportation channel, the suspended casting method is usually adopted to ensure its navigation capacity is not affected. For approach bridges and overpasses, when the foundation is good, the support cast-in-place method is usually adopted. When it is too costly to treat the foundation, precast beams are usually used, that is, precast beams are prefabricated in the beam yard and transported to the installation location by transportation equipment after prefabrication. After the beam casting is completed or before installation, the beam needs to be placed on a temporary support to dry, solidify and rotate. To support the temporary support, the support foundation is a reusable support foundation support block formed by casting a steel support foundation. When in use, the temporary support foundation needs to be moved and rotated according to the change of the placement position of the beam body.

[0003] Since the gantry crane is limited by its working range during use, the turnover of the support foundation currently used generally adopts equipment such as cranes and vehicle-mounted cranes for turnover and transfer. However, in actual use, although the crane can complete the transfer of the support foundation well, the crane has a large radius of action during use and has high requirements for the surrounding environment. The beam yard and the bridge to be assembled have many equipment, which cause serious interference to the crane's lifting. As a result, it often cannot play its function to the maximum extent during the lifting process, resulting in low work efficiency. In particular, there is not enough space for the crane to be deployed on the bridge to be assembled. The vehicle-mounted crane adopts the rear-mounted crane setting mode when in use, and the load on the front wheel is small. It is easy to oversteer and roll over when turning, and it requires manual driving, which cannot guarantee the safety of use. At the same time, the turnover rate is low, which is not convenient for use in the beam yard and the bridge to be assembled.

[0004] In view of the above problems, it is urgent to design a new type of intelligent installation device and construction method for temporary bridge support foundation to solve the problems existing in the above-mentioned prior art. Summary of the Invention
