Background technology
At present, marine engineering geological mapping probing is general adopts boats and ships to set up to become to float platform and two kinds of methods of hydraulic lifting fixed platform are carried out.The boats and ships platform adapts to the little marine site probing of stormy waves, the control of sea conditions such as its operating efficiency wind-engaging, wave, stream, and general effective operation rate is lower; Though the influence of hydraulic lifting fixed platform wind-engaging, wave, stream is less, the platform of 50-60 square metre of scale only adapts to than shallow water territory (being generally less than 7m) probing, and cost exceeds about one times of the utility model.If need to adapt to bigger depth condition, cost can significantly increase.Along with the construction needs of engineerings such as marine bridge, tunnel, harbour, navigation channel, the probing of marine engineering geological mapping also needs the drilling platform of utility model more.How to make that its accommodation is wider, the effective operation rate is higher, use cost is lower, become those of ordinary skills' technical problem anxious to be solved.
The utility model content
For addressing the above problem, the utility model proposes the marine assembly unit static pressure fixed drilling platform that adopts in a kind of engineering geologic investigation at sea, marine assembly unit static pressure fixed drilling platform in employing the utility model effectively raises the operating efficiency of offshore drilling, can not only adapt to the marine site prospecting requirement that the sea is rough, flow velocity is fast, and it is simple in structure, invest little, the work efficiency height.
The technical solution adopted in the utility model is as follows:
A kind of marine assembly unit static pressure fixed drilling platform, the Platform Deck and the lower support structure that comprise the top trussed construction, it is characterized in that: described lower support structure is made up of the vertical leg post and the anti-sinking gripper shoe of bucket foundation, the vertical leg post of described bucket foundation is fixedly installed on the Platform Deck bottom, described anti-sinking gripper shoe is fixedly installed on the vertical leg column bottom of described bucket foundation, and is supported on the mud face of seabed.
Described marine assembly unit static pressure fixed drilling platform, it is characterized in that: described Platform Deck has 4 cartridge type columns, on the cartridge type column locking device is housed, 4 cartridge type columns insert in 4 vertical leg posts, and by the locking of mortise lock structure, thereby form marine assembly unit static pressure fixed drilling platform.Wherein the diameter of cartridge type column depends on the diameter of vertical leg post.
Described marine assembly unit static pressure fixed drilling platform is characterized in that: the vertical leg post of described bucket foundation is made of the steel pipe of 4 diameters more than or equal to 600mm, and is unified into bucket foundation by the shaped steel welding; The vertical leg post hangs exploration sites by crane ship, is forced into the setting absolute altitude by the concrete ballast piece again.Leg post number, length and the leg column diameter of vertical leg post is by seabottom geology condition and load decision.Be provided with horizontal stand between the described vertical leg post, the number of plies of horizontal stand is decided according to the requirement of leg post slenderness ratio, in order to improve stability of structure.
Described marine assembly unit static pressure fixed drilling platform is characterized in that: described anti-sinking gripper shoe, and form by i iron and steel plate, and be arranged between the vertical leg post.Anti-sinking gripper shoe size is determined according to platform deadweight and platform load size and bearing capacity of foundation soil.Before vertical leg post lifting, install the anti-sinking gripper shoe, go into the seabed with vertical leg post static pressure again, and be supported on the mud face of seabed and steel pipe pile that the vertical leg post forms in the seabed plays together and supports and stabilization.
The beneficial effects of the utility model are: 1) good stability, self-supplying capacity are strong, and capacity of anti-storm is strong.2) accurate positioning can be because of the depth of water, flow velocity, rise ebb and stormy waves influence displacement.3) probing quality and duration progress have very big assurance.4) platform has easyly, firm, makes, installs, removes process operations such as displacement and make things convenient for, can be under rugged environment safe normal construction.Especially suitable stormy waves is big, tidewater anxious, the offshore drilling of short-term.

The specific embodiment
Below in conjunction with specific embodiment the utility model is described further:
As shown in the figure, the marine assembly unit static pressure fixed drilling platform of present embodiment comprises Platform Deck 1, vertical leg post 2 and anti-sinking gripper shoe 3.Vertical leg post 2 and anti-sinking gripper shoe 3 by the bucket foundation of superstructure Platform Deck 1, lower support structure are formed.The vertical leg post 2 of bucket foundation is fixedly installed on Platform Deck 1 bottom, and anti-sinking gripper shoe 3 is fixedly installed on vertical leg post 2 bottoms, and is supported on the mud face of seabed.Platform Deck 1 has 4 cartridge type columns 4, and 5,4 cartridge type columns of locking device 4 are housed on the cartridge type column 4 insert in 4 vertical leg posts 2, and by 7 lockings of mortise lock structure, thereby form marine assembly unit static pressure fixed drilling platform.
Arrange a cover drilling rig, aid, mud circulation cleaning equipment, personnel's work facility etc. on the Platform Deck 1.The size of Platform Deck 1 is by using technology to determine.The diameter of cartridge type column 4 depends on the diameter of the vertical leg post 2 that insert the bottom.
The vertical leg post 2 of bucket foundation is made of the steel pipe of 4 Φ 600mm, and is unified into bucket foundation by the shaped steel welding; Vertical leg post 2 hangs exploration sites by crane ship, is forced into the setting absolute altitude by the concrete ballast piece again.Leg post number, length and the leg column diameter of vertical leg post 2 is by seabottom geology condition and load decision.Be provided with horizontal stand 6 between the vertical leg post 2, the number of plies of horizontal stand 6 is decided according to the requirement of leg post slenderness ratio, in order to improve stability of structure.Anti-sinking gripper shoe 3 is made up of i iron and steel plate, and is arranged between the vertical leg post 2.Anti-sinking gripper shoe 3 is determined according to platform deadweight and platform load size and bearing capacity of foundation soil.Before vertical leg post 2 lifting, between vertical leg post 2 bottoms, install anti-sinking gripper shoe 3, go into the seabed with vertical leg post 2 static pressure again, and be supported on the mud face of seabed and steel pipe pile that vertical leg post 2 forms in the seabed plays support and stabilization together.
