The steel hanging box is generally assembled into a whole on the ground or a drilling platform, and the whole is placed down to the periphery of a bearing platform construction area after pile foundation construction is completed. Since the steel hanging box is impacted by water flow and waves when being lowered, the position is easy to deviate, and therefore, a guide limiting device is required to be arranged.
As shown in fig. 1, the steel hanging box lowering mode adopted at present is that steel or a steel support 7 is welded at the positions, which are opposite to pile foundation construction steel pile casings 6, on the four inner walls of the steel hanging box 5 to serve as a guiding and limiting structure, and when the steel hanging box is lowered, the steel or the steel support 7 clings to the steel pile casings 6, so that the steel hanging box can be prevented from generating horizontal positions. However, the requirements of the structure on the size and the welding position precision of the guide steel or the steel support are higher, if the welding position has deviation or is smaller in size, the guide steel cannot be clung to the steel pile casing, the lowering precision of the steel hanging box can be influenced, and if the width of the steel or the steel support is larger than the design distance between the steel hanging box and the steel pile casing, the steel hanging box cannot be normally lowered. In addition, once deviation of the guide structure is found when the steel hanging box is lowered, on-site adjustment cannot be performed, and only the steel hanging box can be hung back to the platform for reworking, so that the construction progress is affected.
Disclosure of Invention
The utility model aims to solve the problems and provides a steel hanging box lowering guide limiting structure convenient to install and adjust, and the lowering precision and the construction progress of the steel hanging box are guaranteed.
The technical scheme of the utility model is as follows:
the utility model provides a steel hanging box descends direction limit structure, steel hanging box is used for transferring to the aquatic cushion cap construction district periphery, and aquatic cushion cap construction district is equipped with a plurality of pile foundation construction steel and protects a section of thick bamboo, and the design has certain interval, its characterized in that between steel hanging box inner wall and the steel protection section of thick bamboo: the steel hanging box is characterized in that a group of guiding limiting devices are arranged on the inner wall of each side of the steel hanging box and correspond to at least one pile foundation construction steel pile casing respectively, each group of guiding limiting devices comprises two rows of supporting rods which are horizontally arranged, each row of supporting rods comprises at least two supporting rods which are vertically distributed along the side wall of the steel hanging box, a connecting plate is welded at the rear end of each supporting rod, the connecting plate is fixedly connected with the side wall of the steel hanging box through bolts, a guiding limiting steel pipe is welded at the front end of each row of supporting rods, the distance between the two guiding limiting steel pipes is smaller than the diameter of the steel pile casing, and the distance between the guiding limiting steel pipes and the side wall of the steel hanging box is larger than the design distance between the steel pile casing and the side wall of the steel hanging box.
The steel box guide device is simple in structure and convenient to install, the distance between the two guide limit steel pipes of each group of guide devices can be adjusted, the guide steel pipes can be ensured to be clung to the steel casing, and the lowering precision and the construction progress of the steel box are ensured.

Detailed Description
As shown in fig. 1, 2 and 3, the underwater bearing platform construction area is provided with a plurality of pile foundation construction steel pile casings 6, the steel hanging box 5 is to be lowered to the periphery of the underwater bearing platform construction area, and a certain distance is designed between the inner wall of the steel hanging box 5 and the steel pile casings 6. The steel hanging box 5 is provided with a group of guiding limiting devices corresponding to at least one pile foundation construction steel pile casing on each side inner wall respectively, each group of guiding limiting devices comprises two rows of supporting rods 1 which are horizontally arranged, each row of supporting rods comprises at least two supporting rods which are vertically distributed along the side wall of the steel hanging box, a connecting plate 2 is welded at the rear end of each supporting rod 1, the connecting plate 2 is fixedly connected with the side wall of the steel hanging box 10 through bolts 3, a guiding limiting steel pipe 4 is welded at the front end of each row of supporting rods 1, the distance between the two guiding limiting steel pipes 4 is smaller than the diameter of the steel pile casing 20, and the distance between the guiding limiting steel pipes 4 and the side wall of the steel hanging box 10 is larger than the design distance between the steel pile casing 20 and the side wall of the steel hanging box 10.
In the concrete implementation of the utility model, in order to avoid the steel casing from expanding the two rows of supporting rods, the two rows of supporting rods 1 of each group of guiding limiting devices can be arranged in a splayed shape according to the plane, and the distance between the rear ends of the two rows of supporting rods is larger than the distance between the front ends.
When the utility model is embodied, the lower end of one side of each guiding limit steel pipe 4 facing the steel casing 20 can be cut into a groove structure, and when the steel hanging box starts to be put down, a certain distance is reserved between the groove of the lower end of the guiding limit steel pipe and the steel casing, so that the guiding effect on the steel hanging box is realized.
