The invention has the advantages of high rigidity and good durability.
Description
Technical Field
The utility model relates to a deep water wharf structure, specifically speaking are whole prefabricated formula wharf structure off shore that combines suction bucket and circle caisson.
Background
With the gradual development of coastlines in China, large deepwater wharfs gradually become a development trend, but face two problems in the construction process. On one hand, the wharf is in open sea, the shielding is less, and the wave force directly acting on the wharf structure is larger; on the other hand, a plurality of seabed places have thick soft soil layers, the bearing capacity of the foundation is low, and special requirements are made on the bearing characteristics of the wharf structure type.
The structural forms which can be adopted in the deep water wharf mainly comprise a gravity type structure, a pile foundation type structure, a submerged large-diameter thin-wall structure and the like, wherein the gravity type structure has good durability, but has a large self weight, has higher requirement on the bearing capacity of a foundation and is not suitable for a soft foundation; although the pile foundation structure can solve the problem of soft soil foundation to a certain extent, the pile foundation structure is easy to displace in deep water and may influence the use of a wharf to a certain extent; the immersed large-diameter thin-wall structure can fully utilize the bearing capacity of a soil body on the premise of not excavating a soft foundation, and is better suitable for various bad foundations, but the existing immersed large-diameter thin-wall structure also has the defect of poor integral rigidity and needs to be improved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a higher wharf structure of bulk rigidity. The utility model discloses a combine together the bucket form basis of suction type and circle caisson structure, make full use of gravity type caisson integral rigidity is big, the advantage that the durability is good when the good characteristic of bearing on the soft soil foundation of performance suction bucket. The technical scheme is as follows:
a construction method of an offshore wharf with a suction barrel and a round caisson integrally prefabricated, wherein the constructed wharf comprises at least one unit, and each unit comprises a wharf cover plate, a suction barrel and a round caisson; the suction barrel comprises a lower inner barrel, a lower outer barrel and a lower cross-shaped inner partition plate, the round caisson comprises an upper inner barrel, an upper inner barrel and an upper cross-shaped inner partition plate, the lower inner barrel and the upper inner barrel are consistent in size and correspond in position, and the lower outer barrel and the upper outer barrel are consistent in size and correspond in position.
Preferably, the upper outer drum is provided with a groove on one side and a cooperating lug on the other side, and when the dock is formed of a plurality of units, adjacent grooves and lugs form a cavity when two adjacent units are butted.
A section of the outer barrel wall from a designed low water level to the top end of the upper outer barrel is provided with a local thickened part, and the local thickened part and the side surface of the wharf cover plate form a plane.
A wave wall and a wheel protecting bank are arranged on the wharf cover plate.
The suction bucket and the novel offshore deep water wharf structure integrally prefabricated with the round caisson are relatively uniform in overall stress, and if the upper bucket wall is appropriately perforated, the suction bucket can be made into a through type, so that the wave force is reduced. If no hole is formed, the wharf berth can be arranged on the side of the wharf close to the shore, and the side close to the sea also serves as a breakwater, so that the mooring stability of the ship in the berth is greatly improved, the respective advantages of a thin-wall submerged foundation and a round caisson are effectively combined, and the method has a good application prospect in a muddy coast. Meanwhile, the operation time on the offshore site is relatively short because the main body part of the structure is integrally prefabricated in a prefabrication field.

Detailed Description
The present invention will be described with reference to the accompanying drawings and examples.
The utility model discloses a suction bucket and the whole novel off-shore deep water wharf structure of prefabricated formula of round caisson every group structure comprises reinforced concrete cask 1, interior round bucket 2, cross inner baffle 3, basic apron 4, wharf apron 5, wave wall 6, fender bank 7 and pier upper portion facility. The lower suction barrel (including the parts 1, 2 and 3 below 4) sinks into the soft soil foundation to provide bearing capacity; the base deck 4 and above is a round caisson ( sections 1, 2 and 3 above 4) that provides a platform for quay operations and vessel berthing. To facilitate the docking and installation of the quay crash, a section of the outer barrel wall from the design low water level to the top of the barrel is thickened appropriately to form a local thickened portion 9, which is made planar with the side of the quay cover 5. The indirect seam of the adjacent upper outer barrel 1 is treated, groove lugs 8 are arranged on two sides of the upper part of the outer barrel 1, the adjacent groove lugs 8 are butted to form a cavity, and concrete or filling block stones are poured in the cavity.
This new structure can be prefabricated and constructed in the following order: firstly, a transportation bottom plate is manufactured and simultaneously used as a platform die for integral prefabrication of a structure, then a prefabrication and delivery method of a large caisson is used for reference, an inner barrel, an outer barrel and a cross-shaped inner baffle plate 3 at the lower part are integrally prefabricated on the transportation bottom plate by adopting a sliding type template technology, then a foundation cover plate 4 is cast in place, an inner barrel, an outer barrel and a cross-shaped inner baffle plate 3 at the upper part are integrally prefabricated by adopting the sliding type template technology again, the inner barrel, the outer barrel and the cross-shaped inner baffle plate 3 at the upper part are integrally delivered from a prefabrication field by adopting construction technologies such as air bag jacking and delivery, the structure is delivered to a construction site by referring to a towing mode of the round caisson, then the structure is submerged by utilizing a negative pressure sinking process, and then a wharf cover plate 5, a wave wall 6, a wheel guard 7 and facilities at the.
