Abstract
The utility model provides an offshore wind power is stake under water and is inserted shoulder formula casing structure, steel-pipe pile top adapter sleeve below the sea, sheathed tube top is located the sea and the bottom is equipped with inserts the point, the top surface of steel-pipe pile be equipped with insert sharp assorted recess, will insert the point during installation and insert in the recess with adapter sleeve and steel-pipe pile, then the pile driver is applyed the striking to sheathed tube top, wait that the steel-pipe pile is squeezed into and demolishs after the required degree of depth. Through the use of the offshore wind power underwater pile shoulder-inserting type pile casing structure, the pile driver can carry out required pile driving operation on the sea surface, so that the construction difficulty is reduced; meanwhile, the assembly and disassembly operation of the sleeve and the steel pipe pile is convenient and quick, the structure of the steel pipe pile is not damaged, and the construction efficiency and the stability can be effectively improved; and the sleeve can be recycled to reduce the consumption of materials.
Description
Technical Field
The utility model relates to an engineering pile construction assists utensil, especially relates to an offshore wind power is stake under water and is inserted shoulder formula and protect a section of thick bamboo structure.
Background
The pile top of the steel pipe pile in the deep sea area needs to be driven into the sea surface, however, in view of the geological conditions of some seabed, the pile foundation can encounter weathered rock geology many times in the installation process, so that the construction difficulty of the steel pipe pile is very large, and the pile is difficult to directly drive in place. The existing construction methods include welding an elongated steel pipe at the top of a steel pipe pile, piling the steel pipe after the elongated steel pipe is exposed out of the sea surface, and cutting the elongated steel pipe from the steel pipe pile by underwater cutting after the pile is driven in place. However, the construction method is complex, the reusability of the lengthened steel pipe is low, the underwater cutting difficulty is extremely high, the construction efficiency is low, the steel pipe pile structure is easy to damage during welding and cutting, and the construction stability is reduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a but reuse and offshore wind power of being convenient for construction operation insert shoulder formula under water and protect a section of thick bamboo structure to reduce the construction degree of difficulty and improve the efficiency of construction.
Offshore wind power is stake under water and is inserted shoulder formula and protect a section of thick bamboo structure, including pipy sleeve pipe, sheathed tube top is located the sea, sheathed tube bottom and steel-pipe pile's top interconnect, and the sheathed tube bottom surface is equipped with to the convex point of inserting of steel-pipe pile, the top surface of steel-pipe pile is equipped with undercut's recess, insert in the point inserts the recess and reciprocal anchorage.
The offshore wind power underwater pile shoulder-inserted pile casing structure of the utility model has the advantages that in the construction work of the steel pipe pile, the insertion tip of the sleeve is inserted into the groove of the steel pipe pile, and the sleeve and the steel pipe pile are fixed with each other, so that the top end of the sleeve is exposed out of the sea surface; and then the pile driver is used for driving the top end of the sleeve to the seabed, and after the steel pipe pile is driven to the required depth, the sleeve is taken down from the steel pipe pile. Through the use of the offshore wind power underwater pile shoulder-inserting type pile casing structure, the pile driver can carry out required pile driving operation on the sea surface, so that the construction difficulty is reduced; meanwhile, the assembly and disassembly operation of the sleeve and the steel pipe pile is convenient and quick, the structure of the steel pipe pile is not damaged, and the construction efficiency and the stability can be effectively improved; and the sleeve can be recycled to reduce the consumption of materials.

Detailed Description
The utility model provides an offshore wind power is stake under water and is inserted shoulder formula and protect a section of thick bamboo structure, includes pipy sleeve pipe 1, and sheathed tube top is located the sea, sheathed tube bottom and steel-pipe pile 2's top interconnect, and sheathed tube bottom surface is equipped with to the convex point 3 of inserting of steel-pipe pile, and the top surface of steel-pipe pile is equipped with undercut's recess, inserts in the point inserts the recess and reciprocal anchorage.
In the offshore wind power underwater pile shoulder-inserted pile casing structure, during the construction work of the steel pipe pile, the insertion tip of the sleeve is inserted into the groove of the steel pipe pile, and the sleeve and the steel pipe pile are mutually fixed, so that the top end of the sleeve is exposed out of the sea surface; and then the pile driver is used for driving the top end of the sleeve to the seabed, and after the steel pipe pile is driven to the required depth, the sleeve is taken down from the steel pipe pile. Through the use of the offshore wind power underwater pile shoulder-inserting type pile casing structure, the pile driver can carry out required pile driving operation on the sea surface, so that the construction difficulty is reduced; meanwhile, the assembly and disassembly operation of the sleeve and the steel pipe pile is convenient and quick, the structure of the steel pipe pile is not damaged, and the construction efficiency and the stability can be effectively improved; and the sleeve can be recycled to reduce the consumption of materials.
The offshore wind power underwater pile shoulder-inserted pile casing structure has the advantages that the diameter of the casing 1 is consistent with that of the steel pipe pile 2, so that the pile driving precision is guaranteed, and the transmission of force in the pile driving process is improved. In addition, the top surface of the steel pipe pile 2 is provided with an annular sheath 4 along the outer wall of the steel pipe pile, the inner side of the sheath is provided with a groove connected with the sleeve insertion tip, the connection strength is improved through the structure, the stability of force transmission is also improved, and therefore the construction precision and accuracy are improved. In addition, a sealing ring 5 is arranged between the inserting tip 3 of the sleeve 1 and the inner wall of the groove of the steel pipe pile, so that the sealing performance between the sleeve and the steel pipe pile is improved, the effect of isolating seawater is achieved, and the requirement of a slurry reverse circulation drilling process is met.
