Description

Torpedo anchor foundation containing grouting plate knot body and construction method thereof

Technical Field

The invention relates to the technical field of deepwater net cage anchoring foundations, in particular to a torpedo anchor foundation comprising a grouting plate knot body and a construction method thereof.

Background

At present, offshore culture in China has the problems of over-development near shore and insufficient utilization in deep water areas. The offshore culture area is mainly concentrated in the shallow gulf of the sea within the deep line of 15 meters and the like, the area is too saturated, and the utilization rate of the sea area with the depth of more than 20 meters is still less than 1 percent and is far lower than the level of developed countries such as the United states, Japan and Norway. Therefore, the development of offshore deep-water cage culture becomes a long-term strategy for guaranteeing food supply and safety in China, and becomes a necessary choice for expanding food production space.

The anchoring system is the foundation of the net cage in water, and the uplift bearing capacity of the anchoring system directly influences the safety of the net cage. Under the severe weather condition, the cases that the net cage is damaged by wind waves and is sunk due to the failure of the anchoring system are not enough. China is attacked by a plurality of superstrong typhoons in coastal years, and seawater net cages within the influence range of typhoon paths are seriously damaged, so that the seawater net cage culture industry is in a state of eating by the weather to a certain extent. For example, the deepwater net cage aquaculture industry in Hainan province suffers devastating attack and loss in the annual ultra-strong typhoon, wherein most of the disaster-stricken deepwater net cages are blown away and damaged due to the damage of anchoring foundations. Although the cost of the anchoring foundation is not large in proportion to the total price of the whole net cage system, the whole net cage system is completely covered after the anchoring foundation fails, and the anchoring foundation has an important function of controlling the overall stability of the net cage.

The common net cage anchoring foundation forms include an iron anchor, a wood pile anchor, a cement pier anchor and the like, but the anchoring foundation can hardly meet the requirements of large-scale deep water net cages and single-point anchoring. With the development of technology, torpedo anchors are also gradually introduced into the anchoring base of net cages. The fish-thunder anchor is one of power penetration anchors, and the shape of the anchor is similar to a fish-thunder, so the fish-thunder anchor is named. The torpedo anchor can be divided into two types, namely a tail wing type and a tailless wing type, and the anchor body with the tail wing type is generally provided with 4 tail fins. The torpedo anchor is cylindrical in shape, hollow inside, can be filled with high-density materials such as concrete, waste metal and the like to increase the self weight and reduce the center of gravity of the anchor so as to maintain the stability of the torpedo anchor, and the lower end part of the torpedo anchor is conical so as to be conveniently penetrated into seabed soil, as shown in figure 1. The torpedo anchor is fast and convenient to install, does not need any external force during installation, only needs to be vertically released at a position which is high enough away from the seabed so that the torpedo anchor falls down by the gravity of the torpedo anchor, and penetrates through the seabed to a certain depth by the huge inertia force caused by high acceleration when the torpedo anchor collides with the seabed. The release height is usually such that a final collision velocity of 17m/s is reached at a distance of 30m from the seabed, a penetration depth of about 7m, and above 30m/s at 150m, a penetration depth of about 20 m.

The method is characterized in that ① has a relatively shallow water depth and a limited height when the torpedo anchor is freely dropped compared with a deep sea floating platform, the torpedo anchor is difficult to penetrate into a deeper seabed, the size and the weight of ② torpedo anchors (otherwise, the cost is too high to popularize) are greatly reduced when the torpedo anchor is used as a foundation of the anchoring of the net cage, the weight reduction of the torpedo anchors also causes the torpedo anchors to be difficult to penetrate into the deeper seabed, ③ has a relatively small frictional resistance between the torpedo anchors and the seabed if the surface soil body of the seabed is thick mucky soil, the strength is low, although the torpedo anchors can penetrate into the seabed with a large depth by means of self weight, the four circles of the torpedo anchors are surrounded by the mucky soil, the torpedo anchors have a relatively small frictional resistance with the seabed, the torpedo anchors have a relatively small frictional force, the requirement for meeting the requirement that the requirement of ④ for the requirement of the relatively high strength, and the requirement of the lower strength of the torpedo anchors for gradually restoring the original ground soil body of the torpedo anchors, and the upper part of the torpedo anchors can be restored by the relatively shallow soil body, and the upper part of the torpedo anchors in the seabed.

The problems concerned by the present invention are: in the sea area with the water depth of 20-40 m, the strength of the soil body on the surface layer of the seabed is relatively low (if the soil body on the surface layer of the seabed is deep mucky soil, or the strength of the soil body on the surface layer of the seabed is relatively high but is low because the fish torpedo anchor is scoured and damaged in the process of penetrating into the net cage, how to enable the fish torpedo anchor to have larger uplift-resistant bearing capacity is adopted.

Detailed Description

Referring to the attached drawings, the torpedo anchor foundation comprising the grouting plate knot body comprises a torpedo anchor 1 and a steel bar net piece 2, an anchor chain 5 is connected to the upper end of the torpedo anchor 1, the steel bar net piece 2 is of a concave shape with a low middle part and a high periphery and is positioned above the torpedo anchor 1, a plurality of construction ropes 3 are respectively connected to the periphery of the steel bar net piece 2, one sides of the construction ropes 3 are respectively connected with a grouting pipe 4, the upper part of the torpedo anchor 1 and the outer part of the steel bar net piece 2 are wrapped with the grouting plate knot body 6, and the anchor chain 5 penetrates through the steel bar net piece 2 and the grouting plate knot body 6 and extends out of the upper end of the grouting plate knot.

The above-mentioned terms of orientation such as "upper portion", "inner portion", etc. are determined based on the attitude of the torpedo anchor at the time of construction. During construction, the torpedo anchor 1 vertically penetrates into the seabed and the reinforcing mesh 2 is in flat contact with and sinks into the soil body of the seabed, as shown in figure 5. 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 above-described orientations or positional relationships are based on the orientations or positional relationships shown in the drawings and are for convenience of description only, and are not intended to indicate or imply that the referenced devices or components must have a particular orientation, configuration and operation, and therefore should not be construed as limiting the present invention.

The above mentioned torpedo anchor is one of the power penetration anchors, and the shape of the anchor itself is similar to torpedo, so that it is named torpedo anchor. The torpedo anchor can be divided into two types, namely a tail wing type and a tailless wing type, and the anchor body with the tail wing type is generally provided with 4 tail fins. The torpedo anchor is cylindrical in shape, hollow inside, can be filled with high-density materials such as concrete, waste metal and the like to increase the self weight and reduce the center of gravity of the anchor so as to maintain the stability of the torpedo anchor, and the lower end part of the torpedo anchor is conical so as to be conveniently penetrated into seabed soil, as shown in figure 1. The torpedo anchor is fast and convenient to install, does not need any external force during installation, only needs to be vertically released at a position which is high enough away from the seabed so that the torpedo anchor falls down by the gravity of the torpedo anchor, and penetrates through the seabed to a certain depth by the huge inertia force caused by high acceleration when the torpedo anchor collides with the seabed.

In the invention, the reinforcing mesh 2 is formed by binding circumferential and radial reinforcing steel bars, and the center of the bottom of the reinforcing mesh 2 is provided with a hole 7 for the anchor chain 5 to pass through. Fig. 2 shows only one structural schematic diagram of the steel mesh sheet 2, and the steel mesh sheet 2 may be designed into other shapes according to actual use requirements.

The construction ropes 3 are distributed symmetrically at equal intervals and are bound around the reinforcing mesh 2.

The grouting plate body 6 comprises aggregate and slurry which are formed by consolidation, the aggregate comprises rock blocks, gravels, broken stones or construction waste, and the particle size of the aggregate is larger than the gaps between the steel bars on the steel bar net piece 2.

A construction method of a torpedo anchor foundation comprising a grouting plate knot body specifically comprises the following steps:

(1) and the torpedo anchor penetrates into the seabed: mooring the anchor chain 5 at the upper end of the torpedo anchor 1, namely on the tail boom of the torpedo anchor 1, hoisting the torpedo anchor 1 based on the anchor chain 5 in a specified sea area, releasing the anchor chain 1, and allowing the torpedo anchor 1 to rapidly sink and penetrate into the seabed under the action of self-weight, as shown in fig. 4.

If the soil body on the surface layer of the seabed is deep mucky soil, the strength is low, although the torpedo anchor 1 can penetrate into the seabed with a large depth by means of self weight, the periphery of the torpedo anchor 1 is surrounded by the mucky soil, the frictional resistance between the torpedo anchor 1 and the soil body of the seabed is relatively small, so that the anchoring force of the torpedo anchor 1 is small, and the requirement is difficult to meet.

If the surface layer of the seabed has relatively high strength and the lower part of the seabed has mucky soil with relatively low strength, namely the seabed has a soil layer structure form of hard top and soft bottom, the seabed soil body with relatively high shallow strength prevents the penetration construction of the torpedo anchor 1. If the method is adopted to scour and destroy the seabed soil with relatively high shallow layer strength, although the torpedo anchor 1 is beneficial to being penetrated into a seabed with a large depth, the seabed soil body scoured and destroyed on the upper part of the torpedo anchor 1 has low strength, can be gradually restored after a long time, and cannot be restored to the original state before construction, so that the frictional resistance is small, and the total uplift bearing capacity of the torpedo anchor 1 is limited.

The construction method is not different from the construction of the traditional fish-stone anchor.

(2) And sleeving a steel bar mesh: a plurality of construction ropes 3, generally not less than three, are symmetrically bound around a pre-prefabricated reinforcing mesh 2 at equal intervals, grouting pipes 4 are respectively bound on the plurality of construction ropes 3, and an anchor chain 5 is sleeved in the reinforcing mesh 2 based on a hole 7 at the bottom of the reinforcing mesh, so that the reinforcing mesh 2 slowly sinks along the anchor chain 5 and contacts the seabed; the connection of the plurality of construction ropes 3, the grouting pipe 4 and the steel mesh 2 is shown in fig. 3.

The plurality of construction ropes 3 can control the reinforcing mesh 2 to sink and contact the seabed in a required posture on one hand, and play a role in guiding and fixing the grouting pipe 4 during subsequent water spraying and grouting operation on the other hand.

The grouting pipe 4 is generally a hollow, flexible and seamless plastic pipe, is low in price and does not need to be recycled after construction. The inner diameter of the grouting pipe 4 can be comprehensively set according to specific conditions. The grout pipe 4 should have sufficient strength so that breakage and breakage do not occur during construction.

(3) And jetting, scouring and throwing the aggregate: connecting each grouting pipe 4 with a high-pressure water pump, starting the high-pressure water pump to enable high-pressure water flow to be sprayed out from the lower end of each grouting pipe 4, scouring seabed soil bodies inside and outside the steel bar mesh 2, throwing aggregate into the steel bar mesh, namely, rock blocks, gravels, broken stones or construction waste, enabling the steel bar mesh 2 to sink into the seabed soil bodies under the combined action of water spraying scouring and the self weight of the aggregate, and stopping the spraying scouring and the throwing of the aggregate until the steel bar mesh 2 sinks to the upper end of the torpedo anchor 1 and the volume of the thrown aggregate meets the requirement, as shown in fig. 5.

Aggregates such as rock blocks, gravels or construction wastes are thrown into the reinforcing mesh 2, so that on one hand, the weight of a subsequent grouting slab is increased by using the self weight of the aggregates, on the other hand, the use amount of the grout can be reduced, and the manufacturing cost is reduced. The particle size of the aggregate needs to be larger than the gap between the steel bars on the steel bar mesh 2, but the particle size of the aggregate is not too large, too large and too heavy aggregate is blocked, and the grouting pipe 4 is easy to press, so that subsequent slurry cannot pass through the grouting pipe 4.

In the construction process, based on the high-pressure water-spraying scouring operation of the grouting pipe 4, on one hand, the soft seabed soil around the reinforcing mesh 2 is scoured and blown away, which is beneficial to further sinking of the reinforcing mesh 2, and on the other hand, the subsequent grouting hardened body has less sand (mud) content and higher overall strength.

The clay layer is under the high-pressure rivers scouring action, and small glutinous grain is at first washed away, runs off, and after small glutinous grain rate destroys, the connection of follow-up great skeleton glutinous grain each other takes place to destroy, and finally cohesive soil takes place the wholeness disturbance and destroys, and loose back water content increases, and intensity sharply reduces. The sandy soil layer can be damaged like liquefaction under the action of high-pressure water flow scouring.

The grouting pipes 4 are not only channels for high-pressure water flow, but also channels for grout during grouting, the number of the grouting pipes is multiple (generally not less than three), if an emergency that a certain grouting pipe fails occurs, grouting work can be completed through the rest grouting pipes, and grouting efficiency and safety are improved.

In the construction process, the reinforcing mesh 2 is sunk to the upper end of the torpedo anchor 1, namely the tail parts of the torpedo anchor 1 and are contacted with each other. If the steel mesh 2 sinks too small to be far away from the tail of the torpedo anchor 1, other known technical means can be adopted to promote the steel mesh 2 to further sink until the requirements are met.

The volume of the aggregates required for throwing the aggregates is estimated according to the concave volume of the reinforcing mesh 2. Generally, more and less aggregates are thrown in, and the thrown aggregates are sunk in the reinforcing mesh 2 by using an auxiliary means in the construction process.

(4) Grouting: the high-pressure water pump is removed to connect each grouting pipe 4 with the grouting system, the grouting system is started to enable grout to flow out from the lower end of each grouting pipe 4, the grout gradually fills the inside and the outside of the steel mesh 2, aggregate in the steel mesh 2 is gradually wrapped by the grout, the grouting is stopped after the volume of the injected grout reaches a design value, the grout solidifies or bonds the aggregate and seabed soil and is hardened after wrapping the upper part of the torpedo anchor 1 and the steel mesh 2, a grouting plate knot body 6 is formed on the upper part of the torpedo anchor 1, and the torpedo anchor 1 and the grouting plate knot body 6 on the upper part of the torpedo anchor 1 are combined together to form an anchoring foundation, as shown in fig. 6.

The curing and hardening of the grout needs a certain time, so the anchoring foundation can be put into use after the grout is fully cured and hardened to meet the requirements.

The slurry is gushed out from the lower end of the grouting pipe 4 and is firstly filled to the periphery and the lower part under the action of gravity; after the lower part is filled fully automatically, the slurry is gradually piled up and developed upwards, the slurry is gradually filled in the reinforcing mesh 2 and wraps the periphery of aggregate such as stone, gravel or construction waste, and finally is hardened to form an irregular geometric body. Such irregular geometry is difficult to graphically represent, so the slip sheet structure 6 in a symmetrical state in fig. 6 does not actually exist, and is merely a simple schematic diagram of the slip sheet structure 6, and does not represent an actual situation.

Because the reinforcing bar net piece 2 is close to the tail of the torpedo anchor 1, the slurry extruded and gushed in the reinforcing bar net piece 2 flows to the position near the tail of the torpedo anchor 1, and the tail of the torpedo anchor is wrapped. Therefore, as long as the grouting volume is large enough, the grout can connect the reinforcing mesh 2 and the tail part of the torpedo anchor 1 to form a whole, and the anchor chain 5 penetrates out of the reinforcing mesh 2, so that the torpedo anchor 1 and the grouting concrete slab 6 are stressed together, and the uplift bearing capacity is high.

The grouting volume should be sufficiently large, so that the reinforcing mesh 2 and the aggregate can be completely wrapped under the condition that the grouting liquid flows around. If the grouting amount is too small, the reinforcing mesh 2 and the aggregates cannot be completely wrapped, the exposed part of the reinforcing mesh 2 is corroded under the corrosion action of subsequent seawater, the aggregates which are not hardened into blocks are likely to be washed away by ocean currents, and the bearing capacity and the service life of the anchoring foundation are reduced.

The size and the weight of the fish-thunder anchor 1 can be reduced in the design, and the grouting plate body 6 with large size is adopted, so that the overall cost is low, and the fish-thunder anchor can be popularized and applied to the mariculture net cage with the water depth of 20-40 m.

The grouting plate body 6 is hardened cement mortar, cement paste, concrete paste, steel fiber concrete paste or chemical adhesive. The concrete components of the grout used for grouting can be selected according to the strength requirement of the anchoring foundation, the construction convenience, the construction cost and other factors.

The grouting method of the grouting system is static pressure grouting, pulse grouting, high-pressure jet grouting, electric chemical grouting, compaction grouting, sleeve valve pipe static pressure grouting or directional grouting. The proper grouting method can be selected according to the factors of construction resistance, construction cost and the like of the anchoring foundation.

The grouting slab knot body 6 contains a steel bar net piece, is similar to a reinforced concrete structure, has good integrity and high strength, and is not easy to damage and lose efficacy when in a working state.

The torpedo anchor 1 and the grouting hardened body 6 formed by grouting the upper part of the torpedo anchor form an anchoring foundation together, and the dead weight of the torpedo anchor 1 and the grouting hardened body 6 and the frictional resistance between the torpedo anchor and the seabed soil body form an anti-pulling bearing capacity together, so that the anchoring force of the torpedo anchor is greatly improved. The construction method is simple and convenient to operate, people do not need to be sent to launch, the offshore operation time is short, and the comprehensive cost is low.

The attached drawings only show the conditions of partial shapes and partial connection modes of the torpedo anchor and the reinforcing mesh, according to the proposed idea, the shapes and the connection modes of all the components can be changed to form other related types of torpedo anchor foundations containing grouting plate knots, which all belong to equivalent modifications and changes of the invention, and are not described again here.
