Abstract

The invention discloses a deepwater open type wharf with a combined foundation. A foundation support system of the deepwater open type wharf comprises a caisson gravity structure system and a pile foundation structure system which are fixedly assembled and connected with each other, a caisson is fixed onto a submarine foundation bed in an implantation manner, the pile foundation structure system is of a concrete-filled steel pipe pile bundle structure comprising through long piles and non-through piles, steel pipe piles arranged along the insides of steel casings are driven into a rock-soil bearing stratum to form the through long piles, and the bottoms of the non-through piles are embedded into a top plate of the caisson to be fixedly connected with the top plate of the caisson, so that the wharf with the combined foundation which comprises an open type pile foundation and the gravity caisson is formed. The invention further provides a method for constructing the wharf. The method includes prefabricating the combined foundation on a land; processing the submarine foundation bed; positioning and sinking the combined foundation; manufacturing the through long piles; manufacturing an upper wharf face plate. The deepwater open type wharf and the method have the advantages that merits of the gravity structure and merits of a pile foundation structure are combined with one another, the problem of differential settlement is effectively solved, wharf apron mooring conditions are improved, and the wharf is high in bearing capacity and good in durability.

Description

technical field

[0001] The invention relates to a wharf and a construction method thereof, in particular to a deep-water wharf and a construction method thereof, which are applied to the construction of large deep-water wharves on soft soil foundations, and belong to the technical field of building structures of ports and water conservancy projects. Background technique

[0002] Oil, coal, ore and other bulk cargoes have large volumes and long distances. It is very economical to use large ships to transport them. However, the water depth of general ports is difficult to accommodate these large ships. In order to adapt to the large-scale ships, it is imperative to build a large deep-water offshore terminal. Due to the huge investment in the construction of breakwaters in deep waters, open piers are generally used. At present, most of the open wharves built in China are fixed wharves, and the structural forms are mainly two types: caisson gravity structure and pile foundation...
