Problems solved by technology

[0005] The conventional pile foundation construction process changes more, and the construction period is longer. When the natural conditions of wind, waves, and currents are harsh in the open sea, the construction quality and efficiency will face a greater test

Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] Such as Figure 1-Figure 6 A pile box hydraulic structure is shown, which includes a caisson 1, and the caisson 1 includes a top plate 1.1 and a bottom plate 1.2, and the edges of the top plate 1.1 and the bottom plate 1.2 are connected by a side wall 1.3, and the top plate 1.1, the bottom plate 1.2 and the side wall 1.3 encloses a compartment, which is provided with a partition wall 1.6 that divides the compartment into multiple small compartments, and the top plate 1.1 and the bottom plate 1.2 are provided with a reserved hole 1.4 along the vertical direction, and steel pipes are installed in the reserved hole 1.4 Pile 2, the steel pipe pile 2 is fixedly connected with the caisson 1.

[0047] In this example:

[0048] The steel pipe pile 2 is fixedly connected with the top plate 1.1 of the caisson 1 through the locking devi...

Abstract

The invention discloses a pile box hydraulic structure object and a building method thereof. A sinking box and a steel pipe pile are manufactured onshore together and are conveyed to a construction site in a floating mode, temporary anchoring placing taking is carried out, the steel pipe column is placed in a sinking mode with the sinking box as a construction platform, the sinking box and the steel pipe pile are fixed through a locking device, an on-water temporary construction platform with pile-box combination is formed, bottom plate water stopping of the sinking box is carried out through a water stopping device, dry construction is carried out in the sinking box, post-pouring concrete is cast, and a whole stress structure is formed. Underwater working such as foundation processing is of no need at an early stage, the object can be adaptive to bad wave environment and complex geological conditions at sea, and the object and the method have the advantages of being quick in site construction and low in safety risk.

Description

technical field [0001] The invention relates to the field of hydraulic structure foundation design and construction, in particular to a pile box hydraulic structure and a construction method thereof. Background technique [0002] The pile foundation is composed of piles and pile caps connected to the top of the piles. It has the characteristics of high bearing capacity, small and uniform settlement, and can be applied to almost all kinds of engineering geological conditions and various types of projects. It is especially suitable for Heavy buildings (structures) on weak foundations. Therefore, pile foundations are widely used in various buildings (structures). [0003] The pile foundation can be roughly divided into friction piles and end-bearing piles according to the stress principle of the foundation, and can be divided into prefabricated piles and cast-in-place piles according to the construction method. Among them, prefabricated piles include concrete piles and steel ...
