Self-anchored overwater operation platform and operation method

Abstract

The invention discloses a self-anchored overwater operation platform and an operation method. The self-anchored overwater operation platform is characterized in that an assembled bearing buoyancy tank comprises a left steel buoyancy tank and a right steel buoyancy tank which are fixedly connected through a fixed steel frame; a rail sliding device is formed by parallelly fixing two pieces of square steel at the tops of the left steel buoyancy tank and the right steel buoyancy tank; an annular drilling machine comprises a supporting base which is finely adjusted through sliding of a roller and a drill bit which is arranged in the center of the supporting base and penetrates through a drill hole downwards; the bottom of the roller is movably arranged on a rail sliding system for fine adjustment, and the top of the roller movably supports the base; and a self-anchoring device comprises at least two hydraulic telescopic positioning devices, and each hydraulic telescopic positioning device is telescopically inserted into a riverbed and arranged on the outer side of the left steel buoyancy tank and the outer side of the right steel buoyancy tank. According to the working platform and the method thereof, it is guaranteed that equipment such as a river channel water cross section, a reinforcement cage and a ring drilling machine and auxiliary materials are convenient and fast to move and place, the investment of manpower, machines and materials is reduced, the working efficiency is improved, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of water work equipment, in particular to a self-anchored water work platform and an operation method. Background technique [0002] In the process of bridge pile foundation construction, the conventional bored pile operation platform in water, the water flow is gentle, and the water depth is less than 5m. When constructing bridge piles in rivers with a water depth of less than 5m, two platforms are commonly used. One of them is to use the island building platform, which occupies a large area of ​​the river, and it is inconvenient to move during use; the other is to use a steel structure platform, which is easy to solve in terms of durability and movement. But the disadvantage is that the manufacturing cost is higher. Even if the cost is ignored to carry out water operations, it is still a technical problem to ensure the quality of the pile head and remove the casing during the construction of bored piles o...

Problems solved by technology

[0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a method of using the principle of buoyancy balance to solve the drilling rig, auxiliary accessories and construction loads when piles are formed on the river bed. It is a self-anchored water work platform and operation method that ensures the cross-section of the river, the steel cage, ring drilling rig and other equipment and auxiliary materials are convenient and quick to move and place, reduces the investment of manpower, machinery and materials, improves work efficiency and saves costs
