Clump anchor bottom surface is difficult to fully contact with scraggly hard sea bed, and coefficient of friction between clump anchor bottom surface and hard sea bed is less, therefore, provides larger anchor force to clump anchor, fully can only improve volume and the weight of clump anchor.As still adopted traditional single clump anchor, then causing clump anchor volume very large, being difficult to prefabricated, construction, transport and lifting.So take the thinking of " breaking the whole up into parts ", by multiple component superposition, be assembled into the larger anchor system of weight.And the volume of each component and quality less, adopt conventional method just can prefabricated, transport with lift.This is the thinking of assembled anchor system.
The present invention at sea work progress is as follows:
Each component is transported to the marine site, hard seabed of specifying, determine seabed more smooth, without in the situation of slope, on crane gear suspension hook, the cable wire portion of tiing 5 tangled in main cement anchor main body 1 hangs and stands on predetermined sea, slowly drop in seawater, until the solid cylindrical base plate bottom surface of cement anchor main body 1 steadily contacts seabed, untie cable wire, auxiliary part is mixed again on main for crane gear suspension hook, its cable wire end portion is made to solve 4 secondary suspension hooks, secondary suspension hook is tangled respectively 4 suspension ring 6 of first order balancing weight 2 side, the rope length adjusting each secondary suspension hook guarantees that first order balancing weight 2 level is sling, slowly drop in seawater, take measures the top hollow cylinder making first order balancing weight 2 inner void aim at, entangle the cylinder of cement anchor main body 1, slowly decline until the complete solid cylindrical base plate entangling cement anchor main body 1 of the interior grooves of first order balancing weight 2 again, and the bottom annulus of first order balancing weight 2 steadily contacts with sea bed.After confirming that first order balancing weight 2 entangles the cylinder of cement anchor main body 1 without inclination, exact level, untie cable wire; Repeat said process again, second level balancing weight 3, third level balancing weight 4 installation in position.Confirm each component without inclination, without after warpage, the mutual flat contact of each component, namely whole anchor system has been assembled.
The inner void diameter of the top hollow cylinder of first order balancing weight 2, the inner void diameter of second level balancing weight 3 are identical with the inner void diameter three of third level balancing weight 4, and be greater than the outer dia of the upper cylinder of cement anchor main body 1, this waves in order to what unavoidably occur when declining to component in assembling process, rock and tilt to leave appropriate space, facilitates offshore construction operation.
Each component of anchor system of the present invention, is reinforced concrete prefabricated forming, and the volume of each component and quality are relatively little, facilitates prefabricated, transport and lifts, therefore assembling process is without the need to special transport and crane gear.
In anchor system assembling process of the present invention, do not require that each component strictly, is accurately piled up, as long as the mutual flat contact of each component, without inclination, without warpage.Each component is put in the level of guarantee, in the situation that contacts with each other, if there is the mutual changing of the relative positions, irregular shift phenomenon, it does not affect the normal work of anchor system.The design of each scantling should adapt to offshore construction need for environment in place, makes the physical dimension of each component in assembling, stacking process not occur inclination, warping phenomenon in theory.
