Description
Technical field
The present invention relates to off-shore structure engineering, relate in particular to a kind of multilayer spider structure and construction method thereof.
Background technology
In the structure types on ocean engineering basis, jacket, pile foundation support table, single pile, individual layer spider structure are all the most frequently used foundation structure forms.
Jacket is generally steel truss structure, is generally the little taper stand in large upper end, lower end, and rigidity is large, good stability, with material, save, but that jacket structure rod member connects is comparatively complicated, makes trouble relatively, and processing charges is high.It is supporting and fixed structure that jacket be take the pile foundation that stake top is positioned at below the water surface, and piling construction needs pile follower under water, and difficulty of construction is larger, high to equipment requirement; If in the time of need making Pile, need to drive piles in addition and set up working platform for Pile, thereby increasing more duration and expense.In addition, if adopt the construction technology of after first pile sinking, jacket being installed, face jacket contraposition difficulty.Also have, while if desired cutting stake, the adjustment of jacket verticality under water, these working procedures all will complete under water, can increase more multiplex's phase and expense.
Pile foundation support table structure consists of pile foundation and concrete pier, and stressed comparatively clear and definite, the globality of structure is better.But pile foundation drift is longer under cushion cap, soil rigidity depends on quantity, slope and the pile body stiffness of pile foundation, so general stake number is more.Simultaneously due to the suffered wave lift of the cushion cap of entity and wave force very large, the horizontal force resistant of pile foundation and resistance to plucking ability have been proposed to requirements at the higher level.Building on the water reinforced concrete pile cap needs the equipment such as Large Steel template, mixer ship waterborne, affected greatly by operating mode, and man-hour is long, expense is high.If basic pile foundation uplift resistance does not meet the demands, need the construction of embedding rock, its embedding rock difficulty of construction is larger, long construction period, engineering cost is quite high.
Single pile form of structure is the simplest, and speed of application is fast, and aquatic work amount is little, but thicker for meeting the selection of requirement of strength pile body, thereby need to bear larger horizontal wave force effect.The jib-length of single-pile foundation structure is long, and soil rigidity is relatively less than normal, and free segment displacement is relatively large, is not suitable for deep water area.Single pile structure section is large, wall thickness is large, and from great, rolled steel dosage is large, and large diameter steel pipe pile is had relatively high expectations to lifting, pile driving equipment, and operating expenses is higher.Single pile structure is not adapted at needing the area of pile foundation embedding rock construction at present, because Big-Diameter Rock-Embedded Pile difficulty of construction is large, and construction machinery seldom, and operating expenses is very high.
Individual layer spider structure is the steel rod elements structure that foundation pile and multiway frame form, and foundation pile number is relatively less, and batch production degree is higher, and over-water construction workload is also less, and speed of application is very fast.But structure stress transmits relative complex, and pile foundation drift is large, is not suitable for the region that the depth of water is large.The steel structural rod piece junction factor of stress concentration is larger, and corresponding fatigue resistance is poor, and spider structure is higher for the construction requirement of node processing simultaneously, and leveling difficulty is large, and difficulty of construction and required precision are very high.In the smaller area of bearing stratum cladding thickness, being not too applicable to using this structure, is mainly because need other injection auxiliary pile and erection construction platform to carry out Pile, can cause long in time limit, expense is high.
According to type and the feature of the shallow sea foundation structure forms such as current jacket, highrise pile cap, single pile, individual layer spider structure, respectively there is advantage separately on various bases, also have the following disadvantages, and are summarized as follows:
1, the major advantage of jacket: batch production degree is high, be subject to that wave force is little, structural integrity good, adapt to different water depth region, save material, the duration is short; Its major defect: the difficulty of contraposition under water, verticality are adjusted difficulty, and underwater grouting connection request is high, not too meets the needs of the geological condition of pile foundation embedding rock.
2, the major advantage of highrise pile cap: construction equipment is alternative greatly, structural integrity is better, homogeneous structure greater experience; Its major defect: batch production degree is low, stake number is many, be subject to that wave force is large, reinforced concrete pile cap construction difficulty, over-water construction operation are many, long in time limit, not too meets the needs of the geological condition of pile foundation embedding rock.
3, the major advantage of single-pile foundation: high, the marine operation of batch production degree is few, offshore construction is fast, the duration is short; Its major defect: be not suitable with the darker sea area of the depth of water, be subject to that wave force is large, operating period distortion is large, material usage is large, need large-scale lifting and pile driving equipment, the inapplicable geological condition that needs pile foundation embedding rock.
4, the major advantage of individual layer spider: high, the marine operation of batch production degree is relatively less; Its major defect: piling required precision is high, installation is difficult, leveling difficulty is large, not too meets the needs of the geological condition of pile foundation embedding rock.
Summary of the invention
