Description

The buried consolidation anchor of the Zi Luochong of oceanographic engineering
Technical field
The present invention relates to a kind of anchor heavy stone used as an anchor of water conservancy and boats and ships field of ocean engineering equipment and technology, specifically, it relates to a kind of relying on notes the buried consolidation anchor of Zi Luochong that the super big deadweight sinking of mercury offer is buried, that can be consolidated in riverbed or sea bed with anchor body surrounding soil in anchor body.
Background technology
Mooring system is for most important by the safety and stability of mooring thing. Except boats and ships, marine structure is such as drilling unit, buoy, underwater monitoring system, deep water aquaculture net cage etc., and whether reliable these are by the mooring system of mooring thing, is the key ensureing that it runs at specified location normal safe.
The grip of anchor determines primarily of structure and the weight of anchor. Traditional anchor such as high holding power anchor relies on the weight of anchor chain and anchor to provide restoring force, limits by the movement of mooring object. But, if when meeting with strong wind or billow, owing to anchor chain is long not, anchor does not have enough weight, cause anchor force inadequate, the phenomena of drag of anchor will occur, jeopardize by the safety of the normal operation of mooring object He its surrounding environment.
Current oceanographic engineering is marching to deep-sea, and owing to being subject to the restriction of the depth of water and deck loading etc., traditional anchor peculiar to vessel can not adapt to this kind of working conditions, and novel erecting then is employed to anchor, such as Rocket anchor, and suction anchor caisson, torpedo anchor, and plate anchor, stake anchor etc. Erecting can bear to anchor erects to load, the deadweight of anchor chain and anchor can not only be relied on to provide the reply pulling force of horizontal direction as traditional anchor peculiar to vessel, and thus, this kind erects the conjugated fibre that can adopt wirerope or lighter to the anchor chain of anchor, reduces taking buoyancy aid buoyancy. For erecting to anchor, the consolidation degree of the length of embedment of anchor and its surrounding soil determines its breakout capacity. And existing erecting needs power to help it to imbed to anchor usually, on using, there are many restrictions, with the develop rapidly of China's oceanographic engineering, need badly and find more reasonably novel mooring system.
Finding by prior art documents, Chinese Patent Application No. publication number: 86105227, patent name is: rocket-laid anchor, and this patent comprises: anchor cone, anchor fin, anchor body and anchor chain, it is characterised in that anchor body is one or several solid propellant rocket. When anchor body is launched, solid propellant rocket as anchor body can by self-contained powder charge rapid combustion, generating a large amount of high-temperature high-pressure fuel gas, be transformed into high-temperature fuel gas jet by jet pipe, the very strong driving force utilizing this kind of jet-flow to produce comes in promote anchor body to pour in stratum, waters. Its main weak point is: 1) rocket-laid anchor effect increases with the depth of water and significantly reduces, when the depth of water is bigger, and rocket thrust requirements height. 2) the complete rear anchor body of powder burning forms cavity, weight saving, and bed material can not backfill, and anchor body can not provide enough anchor force.
Chinese Patent Application No.: 201210550429.9, patent name is: a kind of gravity anchor and manufacture method thereof, this patent comprises: anchor body, upper lift ring and transverse arresting apparatus. Upper lift ring is fixed on the top of anchor body, and transverse arresting apparatus is fixed on the bottom of anchor body. It is characterized in that the bottom of gravity anchor adopts turbination structure, can be easy to enter in water-bed mud, thus bigger grip is provided in vertical direction, the anchor body of gravity anchor is fixed with transverse arresting apparatus, can prevent gravity anchor from bigger lateral displacement occurring, upper lift ring and the side suspension ring of gravity anchor are all embedded in anchor body, are connected firmly, add the work-ing life of gravity anchor. Its main weak point is the limited from ponderomotive force of gravity anchor, and anchor can not entirety be buried in the earth, and only the turbination structure in portion can not provide enough big vertical grip on the lower.
In addition, Chinese Patent Application No. is: 200810038546.0, and patent name is: the power embedment anchor of band high frequency micro breadth oscillation, and this patent comprises: anchor head, anchor pole, the anchor wing, anchor chain, built-in motor, motor cable. In cloth anchor process, start motor, anchor body make under motor high frequency micro breadth oscillation around bed material liquefaction, anchor utilizes deadweight and the exciting force of motor to imbed rapidly in earth. Its main weak point is: for permanent mooring system, after anchor installs, and motor has to be trapped in anchor body, cost height. Consequently, it is desirable to develop the novel anchor that more practical cost performance is higher.
Chinese Patent Application No. is 201210153612.5, publication number is 102673737A, name is called: the consolidation type anchor of super holding power to weight ratio and installation method thereof, the patent provides the consolidation type anchor of a kind of super holding power to weight ratio, it is characterized in that this consolidation type anchor is primarily of housing, it is arranged at the container of enclosure interior, nozzle, anchor ring, expanding material, solidify material forms, moveable dividing plate is set in container, container cavity is separated into by described dividing plate, lower two storing chambers, on described, arrange respectively in lower two storing chambers expanding material and can with the solidify material of soil body generation consolidation, the external wall of anchor arranges the nozzle being connected with container. there is following deficiency in the disclosure technology: the anchor body proportion of the disclosure technology at most can only close to 7.8 tons/cubic metre compared with the present invention, and the anchor body proportion of the present invention is close to 13 tons/cubic metre, under identical execution conditions, kinetic energy when the anchor body of the present invention invades the soil body than the anchor body of the disclosure technology to be exceeded about 1 times, the degree of depth that can invade the soil body is much bigger, it is provided that the anti-power of extracting to be exceeded more than 1 times.
