The construction cost of project.
Utility model content
A purpose of the present utility model is to solve at least the above, and provides the advantage that at least will be described later.
The utility model evades wave effect it is also an object that providing one kind, solves mini-plant construction ability not enough
Operation at sea platform.
In order to realize according to these purposes of the present utility model and further advantage, there is provided a kind of offshore operation at sea is put down
Platform, including：
The pile foundation on bank is fixed on, the top surface of the pile foundation sets the crossbeam extended on the water surface；And
Buoyancy tank submerged in water, one end away from pile foundation of its supporting crossbeam, the buoyancy tank and the crossbeam
Between be provided with many support bars.
Preferably, one end of the close described pile foundation of the crossbeam sets ballast box.
Preferably, the inside of the buoyancy tank has receiving space, and the receiving space is provided with water inlet and delivery port, described
Water inlet and discharge outlet connect the first water pump and the second water pump respectively.
Preferably, pressure sensor is set between the pile foundation and the crossbeam, and the pressure sensor is respectively at institute
State the first water pump and second water pump connection.
Preferably, the buoyancy tank is spherical.
The utility model at least includes following beneficial effect：
1st, it is very big by medium-term and long-term wave effect on existing crane barge equipment is bubbled through the water column, this offshore operation at sea one end branch
Support in land, the other end relies on buoyancy tank support, providing buoyancy by buoyancy tank is supported, and buoyancy tank is submerged in below the water surface, energy
It is enough effectively to evade wave effect.
When the 2nd, carrying out land construction using large scale equipment, construction cost is larger, and large scale equipment is located at breakwater temporary section
Levee crown, and need to carry out reinforcement treatment to levee crown, to meet the bearing capacity demand of large scale equipment.This job platform equipment from
Weigh in a basic balance with the ripple towing force plus buoyancy tank buoyancy acted on buoyancy tank, and carry out balancing equipment in bank side end increase counterweight and exist
The additional load produced in operation process.
3rd, during equipment runs to semi-girder leading portion and returns to land, by adjusting the buoyancy of buoyancy tank, job platform is made
Keep horizontal stable.
Further advantage of the present utility model, target and feature embody part by following explanation, and part will also pass through
Research of the present utility model and practice are understood by the person skilled in the art.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model offshore operation at sea platform.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation
Book word can be implemented according to this.
It should be noted that experimental technique described in following embodiments, unless otherwise specified, is conventional method, institute
Reagent and material are stated, unless otherwise specified, is commercially obtained；In description of the present utility model, term " transverse direction ",
" longitudinal direction ", " on ", D score, "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " etc. indicate
Orientation or position relationship be based on orientation shown in the drawings or position relationship, be for only for ease of description the utility model and letter
Change description, be not indicate or imply meaning device or element must with specific orientation, with specific azimuth configuration and
Operation, therefore it is not intended that to limitation of the present utility model.
As shown in figure 1, the utility model provides a kind of offshore operation at sea platform, including：
The pile foundation 5 on bank is fixed on, the top surface of the pile foundation 5 sets the crossbeam 2 extended on the water surface；And
Buoyancy tank 4 submerged in water, one end away from pile foundation 5 of its supporting crossbeam 2, the buoyancy tank 4 with it is described
Many support bars 3 are provided between crossbeam 2.
In another embodiment, one end of the close described pile foundation 5 of the crossbeam 2 sets ballast box 6.
In another embodiment, the inside of the buoyancy tank 4 has a receiving space, the receiving space be provided with water inlet and
Delivery port, the water inlet and discharge outlet connect the first water pump and the second water pump respectively.
In another embodiment, pressure sensor is set between the pile foundation 5 and the crossbeam 2, and the pressure is passed
Sensor is connected respectively at first water pump and second water pump.Pressure sensor is used for monitoring reaction of bearing, prevents crossbeam
Topple, if excessive by water side reaction of bearing, open the second water pump, by the water discharge part in buoyancy tank to increase buoyancy, if
Bank side reaction of bearing is big, is switched on the first water pump in filling a part of water to buoyancy tank, to reduce the buoyancy of buoyancy tank, and purpose is provided to
