Abstract
The invention discloses a multi-base gravity type base structure which comprises a primary gravity base and more than three secondary gravity bases, wherein the secondary gravity bases are connected through a horizontal carriage to form a polygon; the primary gravity base is located in the polygon; the primary gravity base is connected with the secondary gravity bases through the horizontal carriage; and an inclined carriage is fixed on the secondary gravity bases. According to the invention, a single past gravity type base is divided into a plurality of gravity type bases, so that the contact area of the bases and the foundation is increased, the acting force from the bases to the foundation is decreased and the adaptive capacity and the stability of the gravity type bases to the foundation are improved.
Description
Technical field
The present invention relates to a kind of basis of high-rise structure, particularly a kind of gravity type foundation structure of many pedestals.
Background technology
For natural soft soil foundation, the bearing capacity of ground is often difficult to the requirement meeting works, usually needs to build special structural element.
The foundation structure pattern of ocean engineering mainly comprises: single-pile foundation, gravity type foundation, suction type foundation, many pile foundations and floatation type basis.The domestic single gravity type foundation structure generally adopted at present, because himself huge weight can holding structure thing stable, structure is simple, good stability, is widely used in the ocean engineering such as harbour, harbour.As shown in Figure 1, because single gravity type foundation weight is huge, the bearing capacity of sea bed is difficult to meet the demands, and needs to carry out the supporting capacity that jackstone process improves ground.When the depth of water is larger, be all difficult to carry out construction operations such as the dredging operation of sea bed, foundation trench excavation, fill block stone throwing and compactions in layers, huge monomer basis weight also makes transport mounting cost significantly increase.The foundation structure of land wind power generating set also mainly adopts gravity type foundation.For soft foundation, needing adopts various measures carries out weak soil punishment, and working procedure is complicated, and cost is higher, and the single gravity type foundation scale of construction is huge.
Summary of the invention
Technical problem to be solved by this invention is, not enough for prior art, a kind of gravity type foundation structure of many pedestals is provided, improves gravity type foundation to the adaptive capacity of ground and stability, enable gravity type foundation resist larger extraneous moment of torsion, strengthen the resistance to capsizing of gravity type foundation.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of gravity type foundation structure of many pedestals, comprise main gravity base, also comprise multiple secondary gravity base, described secondary gravity base is connected to form a polygon by horizontal shore, described main gravity base is positioned at polygon, and main gravity base is connected by horizontal support bar with each secondary gravity base, and described secondary gravity base is fixed with skewed horizontal load frame.
Preferably, described secondary gravity base quantity is three, and three secondary gravity bases are connected between two by three horizontal shores, form an equilateral triangle, and described main gravity base is positioned at equilateral triangle center.
Preferably, polygon symmetrical centered by described polygon, described main gravity base is positioned at polygon symmetrical centre.
One end of described horizontal support bar is connected with the center of secondary gravity base, and the other end is connected with the center of main gravity base.
Preferably, described skewed horizontal load frame and horizontal plane angulation are 30
0~ 60
0.
Secondary gravity base weight is generally not less than 20% of main gravity base weight.
Compared with prior art, the beneficial effect that the present invention has is: gravity pedestal single for gravity type foundation is in the past split as multiple gravity pedestal by the present invention, increase the contact area of basis and ground, reduce the active force of basis to ground, improve gravity type foundation to the adaptive capacity of ground and stability; When using the gravity type foundation structure of many pedestals of the present invention, the secondary gravity base of varying number can be configured according to engineering geological conditions, the length of adjustment horizontal support and skewed horizontal load, change the distance of secondary gravity base and main gravity base, enable gravity type foundation resist larger extraneous moment of torsion, enhance the resistance to capsizing on basis; The present invention can be used as the basis of the tower-type works such as offshore wind turbine and tidal power generating unit, land wind power generating set.

Detailed description of the invention
As shown in Figures 2 and 3, one embodiment of the invention comprises main gravity base 1, also comprise three secondary gravity bases 2, three secondary gravity bases 2 are connected to form an equilateral triangle between two by three horizontal shores 3, main gravity base 1 is positioned at equilateral triangle center, respectively be connected by a horizontal support bar 7 between main gravity base 1 with three secondary gravity bases 2, one end of described horizontal support bar 7 and the connection of secondary gravity base, the connection of the other end and main gravity base; Three secondary gravity bases 2 are respectively provided with a skewed horizontal load frame 4, and skewed horizontal load frame 4 and horizontal plane angulation are 45
0, the tower cylinder 6 of works is fixed on main gravity base 1 by flange or socket joint component 5, and secondary gravity base 2 is connected by flange or socket joint component 5 with skewed horizontal load frame 4 one end, and skewed horizontal load frame 3 other end is connected with tower cylinder 6 by flange or socket joint component 5.
Secondary gravity base weight is generally not less than 20% of main gravity base weight.
Main gravity base, secondary gravity base, skewed horizontal load frame and horizontal shore can be the component that steel work, reinforced concrete structure or other materials are made.
The gravity type foundation structure Attention problems transportation of many pedestals is: the main gravity base of processing and fabricating, secondary gravity base, horizontal shore, skewed horizontal load frame and the combiner such as flange or socket joint component on land; In special coastal waters, harbour is assembled into entirety; Hang transportation by driving air bag in each secondary gravity base side, make the gross buoyancy of transportation by driving air bag be greater than the total force of gravity type foundation; With tugboat by gravity type foundation integrally dragging to infield, with location barge or anchorage hawser location, regulate the burst size of gas in transportation by driving air bag, control the buoyancy size of transportation by driving air bag, make gross buoyancy be slightly less than total force, thus ensure that basis steadily, evenly declines.
