Intelligent cantilever assembling type long-span bridge wet joint pouring device

Abstract

The invention relates to a cantilever-assembled large-span bridge wet joint pouring intelligent equipment, comprising a bottom plate, a pouring device is arranged at the front end of the bottom plate, a vibrating compaction device is arranged at the rear end of the bottom plate, and the pouring device includes a pouring support frame installed In the perfusion storage box on the bottom plate, a discharge port is arranged on the lower side of the front end of the perfusion storage box, and a perfusion adjustment mechanism is installed on the front end of the bottom plate. The present invention can solve the instability of artificially conveyed and poured concrete existing in the existing wet joint concrete pouring process, and it is easy to make the concrete splash to the position other than the connecting joint. Manual conveying of concrete cannot ensure the uniformity of concrete pouring, and manual use of existing vibration is required. The equipment vibrates and compacts the poured concrete. During the vibration process of wet joint concrete pouring, it is necessary to avoid the reinforcement cage. The operation is complicated, and the concrete cannot be fully vibrated manually, and the compactness of the concrete cannot be ensured, and the concrete will have holes. .

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to intelligent equipment for pouring wet joints of cantilever-assembled large-span bridges. Background technique [0002] Wet joints refer to the joints where prestressed concrete beams are prefabricated in blocks, cantilevered into large-span continuous beams, and cast-in-place concrete is used between the beams to connect the beams into a whole. In the process of wet joint construction, it is necessary to chisel the position of the joint, and weld the reinforcement cage to the position of the joint, so as to improve the construction quality of the wet joint, and then carry out the concrete pouring operation, which is an important part of the wet joint construction. In the process of concrete pouring for wet joints, manual delivery of concrete cannot guarantee the uniformity of concrete pouring. It is necessary to vibrate and compact the poured concrete manually with th...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a cantilever-assembled large-span bridge wet joint pouring intelligent equipment, which can solve the problem of manual conveying and pouring concrete instability in the existing wet joint concrete pouring process, and it is easy to cause concrete to splash onto the joints. At positions other than the joints, manual delivery of concrete cannot guarantee the uniformity of concrete pouring, and it is necessary to vibrate and compact the poured concrete manually with the help of existing vibration equipment. During the vibration of wet joint concrete pouring, it is necessary to avoid reinforcement cages, and the operation is complicated. The concrete cannot be fully vibrated manually, and the compactness of the concrete cannot be ensured. There will be holes in the concrete, which will affect the quality of the project, and there will be safety hazards and other problems. There are safety hazards, it can ensure the uniformity of concrete pouring, and it has the advantages of simple operation, stable work, resource saving, low labor intensity and high work efficiency.
