Abstract

The invention discloses a micro-control device for reducing the plate anchor burial depth loss and a construction method of the micro-control device. The micro-control device comprises a plate anchorand a barrel-shaped foundation. The two sides of the upper portion of the plate anchor are connected with steel rods. The steel rods are connected with the plate anchor through steel cables. In the assembling process, the steel rods are inserted in sleeves on the outer wall of the barrel-shaped foundation, in the construction process, after the plate anchor penetrates into the seabed at the designdepth, the barrel-shaped foundation floats up, an anchor plate of the plate anchor is completely separated from an anchor plate clamping opening of the barrel-shaped foundation, the upper portions ofthe steel rods are still located in the sleeves, the plate anchor is dragged and restrained by the steel rods embedded in the sleeves, and the burial depth loss of the plate anchor in the rotation process is reduced. The rotation process of the plate anchor is actually restrained to a certain degree through the large strength and the large rigidity of the barrel-shaped foundation, rotational motion of the plate anchor can be achieved, too large upward displacement can be avoided, so that the burial depth loss is greatly reduced, and finally the bearing capacity of the plate anchor is improved. The construction method is simple in operation, construction difficulty and consumed hours are not increased, and the performance cost ratio is high.

Description

technical field [0001] The invention relates to the technical field of anchoring of deep-sea floating platforms, in particular to a micro-control device and a construction method for reducing the burial depth loss of flat anchors. Background technique [0002] In recent years, Suction embedded plate anchor, a new type of foundation form, has been widely used in the Gulf of Mexico and African waters. Its main advantages are low cost, accurate positioning and simple construction. The planar shape of the plate anchor is rectangular, and it is fixed vertically in the suction type during installation, and the caisson penetrates to a predetermined depth under the action of its own weight and the negative pressure caused by pumping. The caissons were pulled out after separation from the slab anchors for future reuse. The plate anchor left in the clay seabed is rotated under the traction of the anchor chain until the plate surface is nearly perpendicular to the anchor chain or the ...
