Description
Technical field
The present invention relates to a kind of anchorage equipment and the technology of water conservancy and boats and ships field of ocean engineering, particularly, relating to a kind of interior note of anchor body mercury that relies on provides super large deadweight sinking the buried fixed anchor of Zi Luochong that bury, that can be consolidated with anchor body surrounding soil in riverbed or sea bed.
Background technology
Anchoring system is for most important by the safety and stability of mooring thing.Except boats and ships, ocean structure is as drilling platform, buoy, underwater monitoring system, preventing deep water breeding net case etc., these by the anchoring system of mooring thing reliably whether, be to guarantee its key in the normal safe operation of assigned address.
The grip of anchor is mainly determined by structure and the weight of anchor.Traditional anchor is such as high holding power anchor is to rely on the weight of anchor chain and anchor that restoring force is provided, and restriction is by the movement of mooring object.But, if while meeting with strong wind or billow, because anchor chain falls short of, anchor does not have enough weight, causes anchor force inadequate, and the phenomena of drag of anchor will occur, jeopardize by the safety of the normal operation of mooring object and its surrounding environment.
At present ocean engineering is marching to deep-sea, and owing to being subject to the restriction of the depth of water and deck load etc., traditional marine anchor can not adapt to this service conditions, and novel vertical anchor is employed, as Rocket anchor, and suction anchor caisson, torpedo anchor, and plate anchor, piled anchor etc.Vertical anchor can bear vertical load, can only rely on the deadweight of anchor chain and anchor that the reply pulling force of horizontal direction is provided, thereby the anchor chain of this vertical anchor can adopt wirerope or lighter composition fiber, reduces taking buoyancy aid buoyancy unlike traditional marine anchor.For vertical anchor, the length of embedment of anchor and the degree of consolidation of its surrounding soil have determined its resistance to plucking ability.And existing vertical anchor needs power to help it to imbed conventionally, there are in the use many restrictions, with the develop rapidly of China's ocean engineering, need the more rational novel anchoring system of searching badly.
Find by prior art documents Chinese Patent Application No. publication number: 86105227, patent name is: rocket-laid anchor, this patent comprises: anchor cone, anchor fin, anchor body and anchor chain, is characterized in that anchor body is one or several solid propellant rocket.In the time that anchor body is launched, solid propellant rocket as anchor body can burn self-contained powder charge rapidly, generate 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 of utilizing this jet-flow to produce is come in to promote anchor body and is poured in stratum, waters.Its main weak point is: 1) rocket-laid anchor effect increases with the depth of water and significantly reduces, and when the depth of water is larger, rocket thrust requires high.2) the complete rear anchor body of powder burning forms cavity, weight saving, and bed material can not backfill, 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.The bottom that it is characterized in that gravity anchor adopts turbination structure, can be easy to enter in water-bed mud, thereby provide in vertical direction larger grip, on the anchor body of gravity anchor, be fixed with transverse arresting apparatus, can prevent that gravity anchor from larger lateral displacement occurring, the upper lift ring of gravity anchor and side suspension ring are all embedded in anchor body, are connected firmly, and have increased the service 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 depends on the turbination structure of bottom that enough large vertical grip can not be provided.
In addition, Chinese Patent Application No. is: 200810038546.0, and patent name is: with the power burial anchor of high frequency micro breadth oscillation, this patent comprises: anchor head, anchor pole, the anchor wing, anchor chain, built-in motor, motor cable.In cloth anchor process, starter motor, bed material liquefaction around anchor body makes under motor high frequency micro breadth oscillation, the disturbance force of anchor utilization deadweight and motor is imbedded rapidly in earth.Its main weak point is: for permanent anchoring system, after anchor installs, motor has to be trapped in anchor body, and cost is high.Therefore, need the more practical higher novel anchor of cost performance of development.
Chinese Patent Application No. is 201210153612.5, publication number is 102673737A, name is called: fixed type anchor and the installation method thereof of super holding power to weight ratio, this patent provides a kind of fixed type anchor of super holding power to weight ratio, it is characterized in that this fixed type anchor is mainly by housing, be arranged at the container of enclosure interior, nozzle, anchor ring, expanding material, curing materials composition, movably dividing plate is set in container, described dividing plate is separated into container cavity, lower two supply chambers, on described, in lower two supply chambers, arrange respectively expanding material and can with the curing materials of soil body generation consolidation, the nozzle being connected with container is set on the external wall of anchor.There is following deficiency in the disclosure technology: the anchor body proportion of the disclosure technology can only approach at most 7.8 tons/cubic meter compared with the present invention, and anchor body proportion of the present invention approaches 13 tons/cubic meter, under identical execution conditions, kinetic energy when anchor body of the present invention is invaded the soil body than the anchor body of the disclosure technology will exceed 1 times of left and right, the degree of depth that can invade the soil body is much bigger, and the resistance to plucking providing is exerted oneself and will be exceeded more than 1 times.
Summary of the invention
