The above-mentioned terms of orientation such as "bottom", "outside", "lower", "upper", etc. are determined based on the attitude of the lifted anchoring base at the time of construction. The anchoring base is suspended above the seabed during construction and is in plumb state, as shown in fig. 9. In this posture, the specific direction of each directional word is determined, and directional words mentioned elsewhere in the specification are also estimated according to this posture. The "outer side" of the rotating tail 4 refers to the side farthest from the sleeve 6. The above-described orientations or positional relationships are based on the orientations or positional relationships shown in the drawings and are only for convenience of description and simplicity of description, but are not intended to indicate or imply that the referred devices or components must have a specific orientation, configuration and operation and therefore should not be construed as limiting the present invention.
The three rotating tail wings 4 are evenly and symmetrically welded on the outer side of the hollow sleeve 6, and the included angle between every two adjacent rotating tail wings 4 is 120 degrees. The three fixed tail fins 3 are evenly and symmetrically welded on the outer side of the central round steel 1, and the included angle between every two adjacent fixed tail fins 3 is 120 degrees.
The inner part of the trepanning 2 is in a round hollow shape, and the upper end surface of the trepanning 2 welded on the upper part of the outer side of the fixed tail wing 3 is flush with the top surface of the fixed tail wing 3, as shown in fig. 4. The rotary tail fin 4 rotates around the central round steel 1 based on the sleeve 6, and the posture of the rotary tail fin 4 can be adjusted to enable the trepanning 2 on the rotary tail fin 4 to be coincident with the two trepanning 2 on the fixed tail fin 3 in axis, as shown in figure 3. The trepanning 2 is used for the anchor body 7 to pass through, so that the anchor body 7 can penetrate the lifted anchoring foundation into the seabed. The upper end surface of the trepanning 2 at the upper part is flush with the top surface of the fixed tail wing 3, so that the end 9 of the anchor body 7 can be positioned on the top surface of the fixed tail wing 3, and the anchor body 7 can conveniently penetrate the anchoring foundation into the seabed.
The two trepanning 2 of the fixed tail fin 3 upper portion and lower portion do not have the same function: the load of the upper end 9 of the anchor body 7 directly acts on the upper trepanning 2, namely the upper trepanning 2 needs to bear impact load; while the lower trepanning 2 only serves to ensnare and position the anchor body 7 and does not carry the impact load. Therefore, the height of the lower trepanning 2 can be smaller, and the material used is smaller; the upper trepanning 2 needs to be higher, and the lower end surface of the upper trepanning 2 is in an inclined plane shape, so that the welding length between the upper trepanning 2 and the fixed tail wing 3 is increased, as shown in fig. 3 and 4.
The trepanning 2 on the rotary tail 4 only plays a role in sheathing and positioning the anchor body 7. After the two trepanning 2 on the fixed tail wing 3 and the trepanning 2 on the rotary tail wing 4 are simultaneously sleeved on the anchor body 7, the position of the rotary tail wing 4 is limited and fixed, and the rotary tail wing 4 cannot rotate, as shown in figure 9, so that the integral stability in the construction process is ensured.
The size of the gap on the fixed tail wing 3 is just equal to the size of the outer contour of the rotating tail wing 4, and the rotating tail wing 4 rotates to the gap during construction, so that the fixed tail wing 3 and the rotating tail wing 4 can be spliced into a whole-like plate, and the plate can conveniently penetrate into the seabed due to the friction force between the plate and the seabed soil body, as shown in fig. 3 and 9.
The inner diameter of the sleeve 6 is larger than the outer diameter of the central round steel 1 at the gap of the fixed tail wing 3, and the length of the sleeve 6 is slightly smaller than that of the central round steel 1 at the gap of the fixed tail wing 3. The sleeve 6 is rotatable around the center round steel 1, and lubricating oil (lubricant) may be applied to the inside of the sleeve 6 in order to reduce friction therebetween.
The lifted anchoring foundation is constructed by adopting a fishbolt without a tail wing, and the construction penetration structure comprises an anchor body 7; the interior of the anchor body 7 is hollow, a conical anchor head 8 is arranged at the lower end of the anchor body 7, an end head 9 is arranged at the upper end of the anchor body 7, the outer diameter of the end head 9 is larger than that of the anchor body 7, and a mooring rod 10 is arranged in the end head 9; the outer diameter of the anchor body 7 is smaller than the inner diameter of the trepan boring 2, and the outer diameter of the head 9 is larger than the inner diameter of the trepan boring 2, as shown in fig. 7 and 8. The interior of the anchor body 7 is hollow, a filler 11 is filled in the hollow part, and the filler 11 can be made of high-density materials such as concrete, waste metal and the like, so that the self weight of the torpedo anchor is increased, the gravity center of the torpedo anchor is reduced, and the stability and the verticality of the torpedo anchor in the process of penetrating into a seabed are maintained.
As shown in fig. 11 and 12, the construction method of the lifted anchoring foundation is as follows:
1) the position of the rotary tail wing 4 is adjusted to ensure that the axes of the trepanning 2 on the rotary tail wing 4 and the two trepanning 2 on the fixed tail wing 3 are coincident, as shown in figure 3. The anchor bodies 7 of the three fishstone anchors without the tail wings penetrate through and are sleeved into three rows of trepanning holes 2, a steel cable 13 for construction is bound on a mooring rod 10 at the upper end of each fishstone anchor without the tail wings, one end of an anchor chain 12 is connected to a mooring hole 5 on a mooring foundation, and each anchor body 7 is tightly connected with the trepanning hole 2 by using subsequent releasable auxiliary measures, so that the mooring foundation cannot fall off when the anchor bodies 7 are lifted. The whole is vertically suspended above the seabed based on the stable hoisting anchoring foundation of the three steel cables 13, as shown in fig. 9.
2) The lowering of the anchor chain 12 is carried out for a certain length to make it in a relaxed state and to minimize the influence on the rapid sinking of the anchoring base, and then the synchronous release of the steel cables 13 is carried out to make the anchoring base rapidly sink and penetrate into the seabed under the self-weight action of the torpedo anchor, as shown in fig. 10.
3) The steel cable 13 is synchronously tensioned upwards, the subsequent releasable auxiliary measures are disabled and destroyed in the tensioning process, the anchor body 7 is gradually separated from the trepanning 2, and finally each anchor body 7 is pulled up and removed. The attitude of the mooring foundation after the anchor body 7 is removed is shown in fig. 11, and the construction is finished. Subsequently, under the action of the tension of the anchor chain, the anchoring foundation deflects and displaces correspondingly, and a schematic diagram of the possible working state of the anchoring foundation is shown in fig. 12.
The lifted anchoring foundation is formed by welding the fixed tail wing and the rotating tail wing at an included angle of 120 degrees, the whole anchoring foundation is in a symmetrical state, the structure is simple, the manufacture is convenient, and the whole anchoring foundation has higher strength and rigidity and can bear larger load; during construction, three fishmine anchors without tail wings are sleeved into the trepanning of the lifted anchoring foundation, the lower part of the anchoring foundation is pointed, the anchoring foundation can be penetrated into a deeper seabed under the action of larger dead weight of the torpedo anchor, the installation is convenient, the construction time is short, and the method is very suitable for the construction environment on the sea; the mooring holes are arranged on the rotary tail wing, so that the lifted mooring foundation is in an eccentric state under the action of the anchor chain after penetrating into the seabed, the rotary tail wing can correspondingly rotate under the action of the tension of the anchor chain, the fixed tail wing can be in close contact with the soil body of the seabed as much as possible, the whole body is always in the best state of coping with the tension of the anchor chain by adjusting the posture of the rotary tail wing, and the uplift bearing capacity of the mooring foundation is improved.
