Description
Technical field
Gravity anchor is the utility model is related to, more particularly to a kind of gravity for being distributed widely in the pipe laying barge mooring of calcic rock marine site
Anchor, belong to Offshore Engineering field.
Background technology
Pipe laying barge is a kind of Large marine equipment for being used to lay submarine oil-transportation, gas transmission and aqueduct.According to operation
The depth of water in marine site, pipe laying barge can be divided into deep water pipe laying barge and shallow water pipe laying barge, can be divided into again according to the operational capabilities of pipe laying barge
It is divided into self-propulsion type and non-self-propulsion type pipe laying barge.
For the marine site of widely distributed calcic rock, because the depth of water is generally smaller, so use shallow water pipe laying barge more.Shallow water is spread
Pipe ship is mostly non-self-propulsion type, is positioned by mooring system, i.e.,:Pipe laying barge is before operation is originated, it is necessary to first pass through anchoring system
System by its mooring at sea presumptive area, after the laying of submarine pipeline is completed by loop wheel machine and pipelaying work line etc..Therefore, rationally
The anchorage form of ground selection mooring system is pipe laying barge on the basis of the stable operation in this kind of marine site.
At present, conventional shallow water pipe laying barge anchor type is mainly embedded anchor, suction anchor and flat board anchor etc..Wherein,
Because construction costs is higher, installation difficulty is larger, relatively low for small-sized anchoring system cost performance for suction anchor and flat board anchor;Towing
Embedded anchor is by providing horizontal bearing capacity in anchor insertion soil, still, because its vertical bearing capacity is poor, it is difficult to adapt to heaving pile
Operating mode when vertically tension force is larger.
Utility model content
Main purpose of the present utility model is to overcome disadvantages mentioned above existing for prior art, and provides a kind of widely distributed
In the gravity anchor of calcic rock marine site pipe laying barge mooring, it can not only rely on itself anchor weight and carry with the interaction of anchor subsoil
For anchor force, solve the problems, such as that vertical bearing capacity is poor under the conditions of calcic rock soil matter, substantially increases the anchor of gravity anchor
Gu power;Moreover, it can also make coupled whole mooring system held stationary, and repeatable utilization, it is upper ocean work
The normal work of journey works lays the foundation.
The purpose of this utility model is realized by following technical scheme:
A kind of gravity anchor for being distributed widely in the pipe laying barge mooring of calcic rock marine site, it is characterised in that:Including:One casing, hang down
Straight main hanger and auxiliary hanger on roof box, wherein, hanger in place, casing are installed on the flat board of casing surrounding
Bottom plate on several shear connectors are equably installed.
The inside of the casing is provided with reinforcing plate, and both ends and the flat board of reinforcing plate link together.
The main hanger is trapezoidal, and the centre of main hanger, which is provided with, strengthens area, and several run through is symmetrically arranged with area is strengthened
The lifting hole(eyelet) of thickness of slab.
The auxiliary hanger is arranged symmetrically on the top plate of main hanger both sides, and perpendicular with the direction of main hanger;Auxiliary
Hanger is provided with a lifting hole(eyelet), and is provided with local thickness around lifting hole(eyelet) and strengthens area.
The hanger in place is symmetrically mounted on the both sides of casing;Hanger in place is provided with a lifting hole(eyelet), and around lifting hole(eyelet)
There is local thickness to strengthen area.
The section of the shear connector is in inverted trapezoidal, and the thickness direction of length direction and main hanger is parallel to each other.This practicality is new
The beneficial effect of type:The utility model due to using above-mentioned technical proposal, its can not only rely on itself anchor weight and with anchor subsoil
Interaction anchor force is provided, solve the problems, such as that vertical bearing capacity is poor under the conditions of calcic rock soil matter, carries significantly
The high anchor force of gravity anchor;Moreover, it can also make coupled whole mooring system held stationary, and repeatable profit
With being laid the foundation for the normal work of upper ocean engineering structure.
