The specific embodiment
For further understanding summary of the invention of the present utility model, feature and effect, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Figure 1, the present embodiment has disclosed a kind of novel marine ground investigation platform, mainly by foundation structure 1, auxiliary floating caisson 3, operating platform 4 and connect the above-mentioned some supports 2 that connect and form.
As shown in Figure 2, foundation structure 1 is circular hollow steel design, and its circular internal diameter is 8～13m, and circular external diameter is 10～15m, and the height of foundation structure 1 is 1～3m.In foundation structure 1, be provided with water inlet system and drainage system.
As shown in Figure 3, auxiliary floating caisson 3 is circular hollow steel design, and its circular internal diameter is 5～9m, and circular external diameter is 6～10m, and the height of auxiliary floating caisson 3 is 1～3m.On auxiliary floating caisson 3, be provided with water inlet system and drainage system.
As shown in Figure 4, operating platform 4 is steel work, and on it, being provided with diameter is the exploratory hole 5 of 0.3～1m, and operating platform 4 peripheries are also provided with the safeguard procedures such as railing.
Support 2 is steel pipe or formed steel construction, and the upright projection height of support 2 is 5～50m.The uniform support 2 of some hoops links together foundation structure 1, auxiliary floating caisson 3 and operating platform 4, and wherein foundation structure 1 is positioned at the bottom of support 2, and operating platform 4 is positioned at the top of support 2, and auxiliary floating caisson 3 is positioned at the middle part of support 2.Support 2 and foundation structure 1, auxiliary floating caisson 3, operating platform 4 respectively by welding, bolt is connected or snap ring connects.
The overall height of marine ground investigation platform is definite according to the depth of water situation in required exploration marine site, and general operation platform 4 end faces are than the high 3～5m of design peak level of exploration sites.The position of auxiliary floating caisson 3 on support 2 also will be determined according to the design maximum water level of exploration sites, generally should guarantee that novel marine ground investigation platform sinking is to sea bed, in the scope of the waterline of exploration sites between the structure centre line of the extremely auxiliary floating caisson 3 of end face of auxiliary floating caisson 3.
