Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
In order to illustrate the technical scheme of the utility model, the following description is made by specific examples.
As shown in fig. 1-3, the assembled pavement for open caisson construction provided by this embodiment includes an assembled unit block 1 for being assembled around an open caisson 2, wherein a plurality of transverse holes are formed in the assembled unit block 1, and each transverse hole is further penetrated with a lifting lug 3 in a shape of a Chinese character 'ji'.
The assembly unit blocks of the assembled pavement are prefabricated in a processing plant, are concrete prefabricated members and are transported to a field installation area, lifting operation is carried out by integrally connecting lifting lugs on the top of the assembled pavement through a lifting machine, and the assembly unit blocks are manually connected and installed to connect the assembled pavement unit blocks into a whole.
As an assembly mode, the assembled pavement is formed by assembling left and right rows of assembled unit blocks in a left-right mode and assembling the assembled unit blocks in a front-back mode. As shown in fig. 3, locking structures 4 are respectively arranged at four corners of the assembly unit block, wherein two locking structures 4 are positioned at two sides of one wide side of the assembly unit block, and the other two locking structures are respectively positioned at the ends of two long sides. And connecting and fixing the adjacent locking structures of the two adjacent assembling unit blocks.
When the open caisson is subjected to sand casting to cause the connection damage or partial damage of the assembly unit blocks of the assembly type pavement, a hoisting machine is adopted to be connected with lifting lugs of the assembly unit blocks through tool rigs, the assembly unit blocks at the damaged parts are lifted out, the new assembly unit blocks are replaced, and the annular construction pavement is quickly restored. After the open caisson construction is finished, the connection between the assembly unit blocks is manually released, a hoisting machine is adopted to be connected with the lifting lug through a tool, the assembly unit blocks are removed, and the assembly unit blocks are transported to a next construction area for repeated use.
