Problems solved by technology

The construction of this temporary operation platform takes a long time to dismantle. After the dismantling, the thin steel pipes must be cut off, and the anti-corrosion process should be carried out on the welding parts.
Not only is it time-consuming, but also the safety protection measures are not comprehensive, and the cost of chartering labor hours is relatively high

Embodiment Construction

[0018] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.

[0019] Such as Figure 1-2 As shown, the special operating platform suitable for independent pile offshore construction includes an independent pile tube 1 and a platform bottom plate 3. The platform bottom plate is two semicircular platform bottom plates surrounding the periphery of the independent pile pile tube. The ring edge is hung on the outer wall of the independent pile pipe, and the outer ring edge of the platform bottom plate is provided with railings 6 . The inner ring edge of the bottom plate of the platform is welded with a lifting lug hook 4 through channel steel, and the outer wall of the independent pile pipe is welded with an inner hole hanging block 2, and the lifting lug hook is hung on the inner h...

Abstract

The invention provides a special operation platform suitable for single pile offshore construction. The platform comprises a single pile pipe and two platform bottom plates which are semicircular and surround the periphery of the single pile pipe, the inner ring edges of the platform bottom plates are hung on the outer wall of the single pile pipe, and railings are arranged on the outer ring edges of the platform bottom plates. Lug hooks are welded to the inner ring edges of the platform bottom plates through channel steel, inner hole hanging blocks are welded to the outer wall of the single pile pipe, lugs are arranged on the railings, and each lug is located between every two corresponding lug hooks which are in the same horizontal plane. By means of the operation platform, time for erecting or dismantling a temporary operating platform with piles arranged in the sea is greatly reduced, a lot of construction cost is reduced, and construction safety is guaranteed.

Description

technical field [0001] The invention relates to an operation platform, in particular to a special operation platform suitable for offshore construction of independent piles. Background technique [0002] Among the platforms developed and constructed in shallow sea oilfields, there are many small fixed platforms, which are usually supported by a steel pipe independent pile. The independent pile has the advantages of simple structure, flexible layout, short construction period, low investment, and quick results. It is widely used in the design of torch support piles, trestle support and riser piles and other projects. [0003] During the construction of independent piles, first use the sea fishing boat to hang the steel pipes of the independent piles on the construction site, and after using the pile driver to drive the steel pipes of the independent piles into the seabed to a certain depth, use the gas cutting equipment to pierce the end of the independent pile pipes above th...
