Description
Technical field
The utility model relates to a kind of erecting equipment, particularly relates to the erecting equipment of suction anchor in a kind of deep water.
Background technology
The suction anchor technology is to put forward the sixties in 20th century, just begin the beginning of the eighties to be applied in century in engineering, because the construction of suction anchor technology is simple, and can reclaim reusable characteristics, enjoy people's favor, therefore, domestic each research and unit in charge of construction extraordinarily pay attention to the suction anchor technology.
Suction anchor is exactly a kind of rigidity stub in fact, and its basic structure is the cylinder of a kind of upper end closed, lower ending opening, and has the pump interface that connects pumping system at its top, during installation, utilizes hydraulic pressure that suction anchor anchor cylinder is pressed in the water-bed earth.
The principle of suction anchor pile sinking (suction anchor draining) is: the suction anchor submerged, and the initial penetration into mud that utilizes its deadweight to produce certain depth of penetration forms a bounded system; Use the water in the pumping system suction anchor cylinder, make to produce in the anchor cylinder to be lower than the outer hydraulic pressure of anchor cylinder, utilize the inside and outside Negative Pressure Difference in anchor cylinder top that the anchor cylinder is pressed in the mud.
The principle that suction anchor plays stake (suction anchor water filling) is: by pumping system water filling in the anchor cylinder, utilize the inside and outside positive differential pressure in anchor cylinder top that the anchor cylinder is ejected the mud face.
Suction anchor is widely applied in many ocean engineerings, except reclaiming the repeated usage, has technically and economically outstanding feature:
1) is convenient to install and transport;
2) engineering time short, be convenient at sea relatively atrocious weather gap construction;
3) in place, the position degree of construction and installation, levelness geometric ratio are easier to accurate adjustment, and setting accuracy is high;
4) save material and cheap for manufacturing cost.
Therefore the suction anchor technology is the technology that relatively is worthy of popularization.
