Description
Technical field
It is especially a kind of to carry all kinds of construction machineries, spin the present invention relates to the floating platform that links multi-functional in a kind of well
Turn the operating platform waterborne of construction space in covering well.
Background technique
Open caisson is to make pit shaft on a kind of ground, is tied by the underground for taking soil to be allowed to sink down into underground predetermined depth in well
Structure.During non-drainage subsidence method is well sinking, controls water level in well and water and soil in well is kept to stablize, carry out taking soil under water
Method for sinking.After well sinking depth down, the outer Water And Earth Pressures of well are gradually increased, for guarantee open caisson surrounding enviroment it is impacted compared with
It is small, it is necessary to use non-drainage subsidence method, stablize Water And Earth Pressures inside and outside open caisson, reduce the outer soil body of well and pour in.
When using non-drainage subsidence, suction dredger equipment can not construct on the water surface, flat according to Jing Ding is set up
The support bracket fastened form of platform, cost is larger, and fixed bracket is larger by well sinking bias effect, it is difficult to be all kinds of constructions
Mechanical equipment provides a basis firm level, the workbench not influenced by SEA LEVEL VARIATION in well.
Summary of the invention
The present invention is to provide for the multi-functional floating platform that links in a kind of well, does not arrange for solving all kinds of mechanical equipments in open caisson
It is underwater heavy when abolishing the shaft bottom soil body, equipment firm horizontal base on the water and whole spaces in the revolving coverage method well of well center
Demand.
To solve the above problems, the technical scheme is that multi-functional link floats platform in a kind of well, by seven differences
The floating box of construction, two sections of steel guide rails, four sleeve fixture mechanisms, four sets of tourelle compositions, the buoyancy tank of seven different configurations
The first to the 5th floating box in body forms main floating box, and main floating box two sides are respectively fixedly connected with the 6th floating box and the 7th and float
Cabinet is equipped with steel guide rail on the main floating box, reserves mechanical execution slot among steel guide rail, construction machinery is made to utilize steel guide rail
It realizes on platform from walking, and using intermediate reserved mechanical execution slot, the shaft bottom soil body is carried out broken to take soil；The main buoyancy tank
It is respectively equipped with tourelle and fixed device between body and the 6th floating box and the 7th floating box and the borehole wall, floating box is made to pass through rolling
Dynamic device realizes convolution waterborne in well, and prevents floating platform to further rotate using fixed device after rotating to designated position
It shakes.
It is fixedly connected between the floating box of seven different configurations by bolt.
Four sets of tourelle synchronous rollings, rotate floating box around well center, and mechanical execution slot revolving coverage method is entire
Native space is taken inside well.
The beneficial effects of the present invention are: open caisson is constructed using non-drainage subsidence, when all kinds of mechanical equipments of needs are to shaft bottom soil
When body carries out effectively broken remove, the multi-functional floating platform that links is capable of providing well firm carrying operation platform in well, guarantees
Mechanical equipment all-the-time stable, and can be rotated according to the needs of mechanical equipment, platform around well center, realize that mechanical equipment is complete to shaft bottom
Space covering operation；Simultaneously because platform can be realized equipment to shaft bottom space equipped with tourelle and fixed device, platform
Accurate positioning；Since platform is made of muti-piece cabinet, platform construction influenced by water level height difference variation in well it is smaller, and can root
According to the difference of different caisson structures, reasonable combination variation is carried out, changes planform shape to match construction needs.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the multi-functional floating platform that links in well of the invention.
Specific embodiment
The present invention is further illustrated with embodiment with reference to the accompanying drawing.
As shown in Figure 1, the multi-functional floating platform that links in a kind of well, by the floating box of 7 different configurations, 2 sections of steel guide rails 8,4
9,4 sets of tourelles 10 of sleeve fixture mechanism form, and are connected between the floating box of different configuration using latch, wherein first to the
Five floating box 1,2,3,4,5 form main floating box, and main floating box two sides are respectively fixedly connected with the 6th floating box 6 and the 7th floating box
7, steel guide rail 8 is installed on main floating box, reserves mechanical execution slot among steel guide rail 8, construction machinery on floating box using disposing
Steel guide rail 8 realize on platform from walking, and using mechanical execution slot reserved among floating platform, the shaft bottom soil body is crushed
Take soil.Floating platform realizes convolution waterborne in well by tourelle 10, and utilizes fixed device 9 really after rotating to designated position
No longer with the borehole wall positional shift occurs for platform cabinet of keeping tie.
Floating platform is made of the floating box of multiple and different constructions, and planform shape construction can be adjusted according to well body structure,
Platform construction can not influenced by the variation of well sinking absolute altitude substantially.
Tourelle 10 answers synchronous rolling, rotates floating platform around well center, in the entire well of mechanical execution slot revolving coverage method
Portion takes native space.
First to the 7th floating box 1,2,3,4,5,6,7 is responsible for providing platform floating force-summing device carrying platform basis, is real
Existing equipment over-water construction and rotational positioning it is basic.It breaks ground and inhales mud equipment by, from walking, rolling dress on the realization platform of steel guide rail 8
It sets 10 realization platforms to rotate around well center, fixed device 9 ensures the relative positional relationship of platform Yu well inner wall, so that it is guaranteed that mechanical
Equipment can realize any one of shaft bottom inside position and be accurately positioned, and not arrange to smoothly solve all kinds of mechanical equipments in open caisson
It is underwater heavy when abolishing the shaft bottom soil body, equipment firm horizontal base on the water and whole spaces in the revolving coverage method well of well center
Demand.
Application implementation example of the present invention:
Engineering is Zhengjiang City huge port water factory one phase water intake engineering, and water-fetching head engineering east, west line open caisson are round reinforced concrete
Structure, two caisson structures are identical, open caisson outer diameter 17.6m, blade foot bottom absolute altitude -33.0m, submergence depth 41.2m, sink eventually
The heavy stage meets with 5. silty clay, characteristic load bearing capacity and reaches 260KPa, and 2m below blade foot absolute altitude is horizon d.Due to Gao Shui
The presence of head pressure makes this engineering open caisson native difficulty of construction must be taken larger using non-drainage subsidence construction technology, shaft bottom, needs
Corresponding mechanical equipment is wanted effectively to abolish the soil body under blade foot and bottom beam.By using the present invention, effectively set for all kinds of machinery
It is standby to provide integrated construction platform waterborne in well, it realizes to soil body space all standing in well, and be always ensured that various kinds of equipment is in
In stable, safe and reliable working environment, the construction of open caisson non-drainage subsidence is well realized.
