Fig. 1 overlooks to the plane structure schematic diagram for a specific embodiment of the utility model.
Fig. 2 is that the A-A of Fig. 1 is to structural representation.
Fig. 3 is the distribution map of working region on this offshore boring island.
Each label title is respectively in the accompanying drawing: 1-lifting gear, 2-i iron guide rail and horizontal shift device, 3-spandrel girder, 4-steel caisson, 5-pin plate connector; I-master's platform area, II 1-assistance platform district, II 2-assistance platform district; A-drilling rod district, B-drill main body district, C-slush pump district, D-mud solid controlling and landwaste equipment for drying district, E-generating set and automatically controlled district, F-dry-mixed cement device and skid cementing equipment district.
The specific embodiment
Below with reference to accompanying drawing the utility model content is described further, but actual fabrication structure of the present utility model is not limited in following embodiment.
Referring to accompanying drawing, the legged offshore boring island that is used for marsh and beach area described in the utility model is made up of the steel caisson 4 of bringing outlet valve into of 70~84 (the accompanying drawing illustrated embodiment is 70) 3 meters * 3 meters * 12 meters, be divided into three platform area, wherein main platform area I is made up of 4 * 7 caissons 4, be interconnected to an integral body by pin plate between each caisson, two assistance platform district II 1, II 2Each is made up of 3 * 7 caissons 4, also is interconnected to an integral body by pin plate between each caisson.At two assistance platform district II 1, II 2On two i iron guide rails 2 longitudinally respectively are installed, every guide rail 1 is provided with the horizontal shift device that is made of the displacement fluid cylinder, the range of horizontal shift device is designed to 6~8 meters.All symmetry is equipped with 3 lifting gears 1 that are made of the lifting fluid cylinder on every i iron guide rail, and the maximum lift of lifting gear 1 is 1 meter, and a lift of each lifting gear 1 is more than 250 tons.At two assistance platform district II 1, II 2Three groups of corresponding lifting gears 1 that are provided with on respectively frame middle part that very big 3, the three horizontal spandrel girders 3 of horizontal spandrel girder of rigidity are housed all be connected to one with main platform area I by pin plate connector 5.On main platform area I, also be provided with the caisson feeding/discharging device that is used to adjust the automatic rackwork of rig level of rig unit horizontal level and is used to make caisson 4 water inlets and draws water in addition.
