Foundation construction platform for intertidal zone or offshore zone

Abstract

The invention discloses a foundation construction platform which is used for foundation construction of an intertidal zone or an offshore zone. The foundation construction platform comprises a platform body (1), support legs (5) as well as a first hoisting frame (11) and a first slide rail (21), wherein the support legs (5) are installed at the bottom of the platform body (1); the first slide rail (21) is arranged along the longitudinal direction of the platform body (1); and a first cross beam (111) of the first hoisting frame (11) is installed with a first hoisting part (31), and the first hoisting frame (11) can slide along the first slide rail (21). Therefore, without additionally provided auxiliary equipment, such as a crane and the like, the foundation construction platform can realize the operations of pile taking, pile rotation and the like and reduces the auxiliary construction equipment for the foundation construction platform so that the operation cost of the foundation construction platform is reduced. The invention also provides a foundation construction platform comprising a hoisting device.

Description

technical field [0001] The invention relates to the technical field of tidal flats or offshore construction equipment, in particular to a foundation construction platform for tidal flats or offshore areas. Background technique [0002] With the rapid development of my country's economic construction and the extensive development of offshore resources, various construction equipment used in tidal flat areas have been more and more widely used. [0003] Tidal flat areas generally include areas where water and land intersect, such as inner lakes, inland rivers, and coastal waters. Due to their proximity to water bodies, the foundation bearing capacity of tidal flat areas is relatively poor. In the process of large-scale infrastructure construction, special consideration should be given to foundation construction issues . [0004] In the process of tidal flat or water foundation construction, the infrastructure platform used for piling operations plays a vital role. The quality...

Problems solved by technology

[0005] In a typical foundation construction platform, the platform part is supported on the riverbed or tidal flat by outriggers, the pipe piles are placed on the appropriate position of the platform, and the pipe piles are lifted by a crane (usually a crawler crane) additionally equipped on the platform. After transporting to the construction site and carrying out piling work, the crane can lift another pipe pile again after the whole process from lifting to piling of one pipe pile is completed; The auxiliary working time is long, which seriously affects the work efficiency of piling construction; at the same time, in this typical foundation construction platform, it is necessary to use a crane to perform operations such as picking up piles and turning piles, thereby increasing the number of auxiliary construction equipment and making the foundation construction platform In addition, the tonnage of auxiliary equipment such as cranes used in construction is relatively large, so the overall weight of the foundation construction platform is increased, and the requirements for the carrying capacity of the platform part are relatively high.

[0006] Moreover, the foundation of the outriggers of the above-mentioned foundation construction platform is a flat foundation, which cannot provide sufficient bearing capacity in soft soil foundations in areas such as tidal flats, and is difficult to pull out when it is trapped in the mud layer during the construction process, so it cannot achieve a more flexible construction. Movement, which limits the improvement of the transition speed of the foundation construction platform
