Abstract
The utility model relates to an embedded major diameter many bays section of thick bamboo and pile foundation combination formula artificial island, basic constitutional unit are many bays section of thick bamboo and are located the pile foundation of many bays section of thick bamboo below, many bays section of thick bamboo include major diameter drum, inner baffle includes main baffle and vice baffle, the two crossing department is provided with the pipe that is used for beating the pile foundation of establishing. The utility model is suitable for a soft soil foundation and deep water condition, construction are convenient.
Description
Technical Field
The utility model relates to a harbour coast and coastal waters engineering field specifically are artificial island engineering.
Background
The pipe pile foundation type structure (such as an inverted T-shaped pipe wall pile foundation breakwater, published as CN101314942) is suitable for deep water and soft soil foundations, and has the advantages of light dead weight, high bearing capacity and convenient construction. The large-diameter cylinder structure (such as a steel cylinder with a wide mortise device, with the publication number of CN104099940A) is a large-diameter cylinder made of steel or reinforced concrete, and is divided into a sitting bed type and a sinking type, the structure has good stress characteristic, is convenient and fast to construct, and can be used for quickly building an artificial island. When foundation soil is weak, a large submerged cylinder structure with deep soil penetration depth is needed, and construction difficulty is increased; on the other hand, in the application of the cylindrical structure, the backfill in the cylinder is usually needed to increase the structural rigidity, but the self weight of the backfill is too large to affect the bearing capacity of the cylindrical structure.
SUMMERY OF THE UTILITY MODEL
The utility model aims at combining the advantages of the island can become fast with major diameter drum structure and pipe pile foundation formula structure bearing capacity is strong, the dead weight is light, provides the artifical island structure that is applicable to soft soil foundation and deep water condition, construction convenience. The technical scheme is as follows:
the combined artificial island is characterized in that the multi-compartment cylinder comprises a large-diameter cylinder and an inner partition plate, the inner partition plate comprises a main partition plate and an auxiliary partition plate, and a conduit for driving the pile foundation is arranged at the intersection of the main partition plate and the auxiliary partition plate.
Soft soil foundations are widely distributed in Bohai gulf, Yangtze river mouth, Zhujiang river mouth and Zhejiang and Min coastal areas with active economic development in China, and the thickness is different from several meters to dozens of meters; at present, port, coast and offshore engineering gradually develop to deep water, and so do artificial island construction. In the combined artificial island structure of the sinking type large-diameter multi-bay barrel and the pile foundation, the sinking type large-diameter barrel blocks and retains water, the internal bay of the barrel increases the structural rigidity and forms a conduit at the same time, and the pile foundation in the conduit can increase the vertical bearing capacity and the anti-sliding and anti-tilting stability of the structure; the structure has good bearing property, high construction speed and small material consumption, and has wide application prospect in the muddy coast of China.

Detailed Description
The basic component unit of the combined artificial island structure of the sinking type large-diameter multi-compartment cylinder and the pile foundation consists of a large-diameter cylinder 1, an inner partition plate and the pile foundation. When steel is adopted to manufacture the multi-bay cylinder, the large-diameter cylinder is connected with the inner partition plate in a welding way; when the reinforced concrete multi-bay cylinder is adopted, the large-diameter cylinder and the inner partition plate are respectively prefabricated, and cast in situ during construction to be connected into a whole. The inner partition board is divided into a main partition board 3 and an auxiliary partition board 2, and a pipe is formed at the intersection of the main partition board and the auxiliary partition board for driving a pile foundation. And a water stopping device is arranged between the two adjacent groups of structures.
The main construction process of the sinking type large-diameter multi-compartment tube and pile foundation combined artificial island structure comprises the following steps: when the steel cylinder is adopted, the multi-bay cylinder is prefabricated on land, and is transported out integrally, transported to a construction site in a floating manner and sunk to a specified depth; when the reinforced concrete cylinder is adopted, the cylinder and the main and auxiliary inner partition plates are prefabricated respectively, transported to a construction site in a floating mode, the cylinder is firstly sunk to a specified depth, then the inner partition plates are arranged, and a joint is cast in situ; and finally, placing the pile foundation in the guide pipe, and driving the pile into a specified depth by adopting equipment such as a piling ship and the like.
