Description
Technical field
It is especially a kind of to carry all kinds of construction machineries the present invention relates to the floating platform of multi-functional linkage in a kind of well, spin
Turn the operating platform waterborne of construction space in covering well.
Background technology
Open caisson is to make pit shaft on a kind of ground, and the underground for sinking down into underground desired depth knot is allowed to by being fetched earth in well
Structure.During non-drainage subsidence method is well sinking, controlling in well water level to keep in well, water and soil is stable, is fetched earth under water
Method for sinking.After well sinking depth down, the outer Water And Earth Pressures of well gradually increase, for ensure open caisson surrounding enviroment it is impacted compared with
It is small, it is necessary to using non-drainage subsidence method, Water And Earth Pressures inside and outside stable open caisson, to reduce the outer soil body of well and pour in.
When using non-drainage subsidence, suction dredger equipment can not be constructed on the water surface, be put down according to Jing Ding is set up
The support bracket fastened form of platform, cost is larger, and fixed support is larger by well sinking bias effect, it is difficult to is all kinds of constructions
Plant equipment provides a basis firm level, the workbench not influenceed by SEA LEVEL VARIATION in well.
The content of the invention
The present invention is to provide for the multi-functional floating platform of linkage in a kind of well, is not arranged in open caisson for solving all kinds of plant equipment
It is underwater heavy when abolishing the shaft bottom soil body, equipment firm horizontal base on the water and whole spaces in well central rotation covering well
Demand.
To solve the above problems, the technical scheme is that：The multi-functional floating platform of linkage in a kind of well, by seven differences
The floating box of construction, two sections of main guide rails, four sleeve fixture mechanisms, four sets of active tourelle compositions, seven different configurations
The first to the 5th floating box in floating box forms main floating box, and main floating box both sides are respectively fixedly connected with the 6th floating box and the
Seven floating box, are provided with steel guide rail on the main floating box, reserved mechanical execution groove among steel guide rail, construction machinery is utilized steel
Guide rail is realized from walking on platform, and utilizes middle reserved mechanical execution groove, and broken fetch earth is carried out to the shaft bottom soil body；The master
Active tourelle and fixing device are respectively equipped between floating box and the 6th floating box and the 7th floating box and the borehole wall, makes buoyancy tank
Body realizes convolution waterborne in well by active tourelle, and prevents floating put down using fixing device after specified location is rotated to
Platform, which further rotates, to be rocked.
It is fixedly connected between the floating box of seven different configurations by pin.
Four sets of actives tourelle synchronous rolling, make floating box around well central rotation, mechanical execution groove revolving coverage method
Fetched earth inside whole well space.
The beneficial effects of the invention are as follows：Open caisson is constructed using non-drainage subsidence, when all kinds of plant equipment of needs are to shaft bottom soil
When body carries out effectively broken remove, the multi-functional floating platform of linkage can provide well firm carrying construction platform in well, ensure
Plant equipment all-the-time stable, and can realize that plant equipment is complete to shaft bottom around well central rotation according to the needs of plant equipment, platform
Space overlapping operation；Simultaneously because platform is equipped with active tourelle and fixing device, platform can realize equipment to shaft bottom
Space is accurately positioned；Because platform is made up of polylith casing, platform construction influenceed by water level discrepancy in elevation change in well it is smaller, and can
With the difference according to different caisson structures, reasonable combination change is carried out, changes planform shape to match construction needs.
Brief description of the drawings
Fig. 1 is the structural representation of the multi-functional floating platform of linkage in the well of the present invention.
Embodiment
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the multi-functional floating platform of linkage in a kind of well, by the floating box of 7 different configurations, 2 sections of main guide rails 8,4
9,4 sets of active tourelles 10 of sleeve fixture mechanism form, and are connected between the floating box of different configuration using pin, wherein, first
Main floating box is formed to the 5th floating box 1,2,3,4,5, it is floating that main floating box both sides are respectively fixedly connected with the 6th floating box 6 and the 7th
Casing 7, is provided with steel guide rail 8 on main floating box, and reserved mechanical execution groove among steel guide rail 8, construction machinery is using on floating box
The steel guide rail 8 of placement is realized from walking on platform, and the mechanical execution groove reserved using platform centre is floated, to the progress of the shaft bottom soil body
It is broken to fetch earth.Floating platform realizes convolution waterborne in well by active tourelle 10, and using solid after specified location is rotated to
Determining device 9 ensures that position skew no longer occurs with the borehole wall for platform casing.
Floating platform is made up of the floating box of multiple different configurations, and planform shape construction can be adjusted according to well body structure,
Platform construction can not influenceed by the change of well sinking absolute altitude substantially.
Active tourelle 10 answers synchronous rolling, makes floating platform whole around well central rotation, mechanical execution groove revolving coverage method
Fetched earth inside well 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.Suction mud equipment of breaking ground is realized on platform from walking by steel guide rail 8, is actively rolled
Dynamic device 10 realizes that platform ensures the relative position relation of platform and well inwall around well central rotation, fixing device 9, so that it is guaranteed that
Plant equipment can be realized to any one position of shaft bottom inside and is accurately positioned, so as to smoothly solve all kinds of plant equipment in open caisson
When non-drainage subsidence abolishes the shaft bottom soil body, equipment firm horizontal base on the water and in well central rotation covering well it is all empty
Between 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 circular reinforced concrete structure,
Two caisson structures are identical, open caisson external diameter 17.6m, cutting shoe bottom absolute altitude -33.0m, submergence depth 41.2m, heavy rank eventually of sinking
Section meets with 5. silty clay, characteristic load bearing capacity and reaches 260KPa, and 2m is horizon d below cutting shoe absolute altitude.Due to high water head pressure
The presence of power causes this engineering open caisson to use non-drainage subsidence construction technology, and the shaft bottom difficulty of construction that fetches earth is larger, it is necessary to phase
Plant equipment is answered effectively to abolish the soil body under cutting shoe and bottom girder.By using the present invention, effectively carried for all kinds of plant equipment
Supplied integrated construction platform waterborne in well, realized to soil body space all standing in well, and be always ensured that various kinds of equipment be in it is stable,
In safe and reliable working environment, the construction of open caisson non-drainage subsidence is well realized.
