Description
Technical field
The utility model relates to marine boring and coring technical fields.
Background technique
Port engineering build be unable to do without basement process, no matter reconnoitre or basement process after quality testing, it is often necessary into
The boring and coring operation of row sea.The turbulent river crashes its way through for operation on the sea, if water flow is not isolated with drilling rod, coring direction is just difficult to control
System, is especially taking a core, and when stake diameter is lesser, higher to vertical requirement.
Sea coring mainly transfers casing from boring and coring platform at present, and drilling rod is completely separated with water flow, guarantees drilling
The verticality of coring, but since casing is relatively large in diameter, when the depth of water is shallower, to the of less demanding of hanging device, it can satisfy brill
The requirement of hole coring, but when the depth of water is deeper, the casing for needing to transfer accordingly increases, and weight is consequently increased, to hanging device with
And the requirement of drilling platform also correspondinglys increase, and limits its applicability.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, when a kind of boring and coring at sea is provided, Bu Huiyin
Lead to the inclined marine boring and coring device of drilling rod for flow action.
A kind of sea boring and coring device, it is characterised in that：Including being fixed on the fixing pipe of the overhanging platform of hull, being placed on admittedly
In fixed pipe and bottom stretches out the vertically-guided pipe of fixing pipe nozzle, is placed in vertically-guided pipe and extends downwardly until insertion mud face
Casing, be cased with drilling rod in casing, drilling rod bottom is equipped with corer.
The overhanging platform of hull is the levelling bench parallel with the water surface, and fixing pipe is located at drilling machine perpendicular to overhanging mesa base
Underface.
Fixed bore is greater than 1~2cm of vertically-guided pipe outside diameter；Vertically-guided bore is greater than 1~2cm of sleeve outer；
Casing inner diameter is greater than 2~5cm of drilling rod outer diameter.
Fixed pipe outside diameter is 20~25cm, 12~20mm of wall thickness, 1.5~2.5m of length；Vertically-guided pipe be length 7~
9m, 8~12mm of wall thickness；Casing wall thickness 6mm~10mm.
Casing is formed by continued access above and below more piece tube unit, and the initial and end both ends of every section tube unit are equipped with connection screw thread.
There is baffle at vertically-guided tube top end, and baffle plate frame is set on fixing pipe nozzle.
The utility model carries out the measure of three-level water proof using fixing pipe, vertically-guided pipe, casing, is welded using fixing pipe
In hull, guarantee the Relative vertical of fixing pipe and hull, then be put into vertically-guided pipe in fixing pipe, due to diameter between two pipes
It differs smaller, ensure that the verticality of vertically-guided pipe, casing is finally placed into vertically-guided pipe up to mud face, by drilling rod
It is separated with water flow, and then guarantees the verticality of boring and coring.Since fixing pipe, vertically-guided pipe, the diameter of casing are relatively small,
The weight lifted when the depth of water is deeper is little, and the Lifting Capacity of drilling machine itself is just able to satisfy requirement, operability, adaptability
By force, convenient for popularization.The utility model passes through the measure of three-level water proof, progressive, increases the anti-pressure ability to water flow, relatively
In the casing of major diameter, and the overall volume and overall quality of water proof pipeline are greatly subtracted, have reduced to hull, hanging device
Performance requirement, have extremely strong operability and applicability.
Detailed description of the invention
Now in conjunction with Figure of description, the technical solution of the utility model is further described.
Fig. 1 is a kind of general illustration of marine boring and coring device；
Fig. 2 is vertically-guided pipe schematic diagram；
Fig. 3 is the schematic diagram of casing.
Wherein：Drilling machine 1, platform 2, hull 3, fixing pipe 4, vertically-guided pipe 5, casing 6, drilling rod 7, corer 8, the water surface 9,
Mud face 10, baffle 11, screw thread 12.
Specific embodiment
Below it is only the implementation example of the utility model, the scope of the utility model cannot be limited with this.I.e. in every case according to this
The variation of unsubstantiality made by utility model application the scope of the patents and modification, should still belong to the range that the utility model patent covers
It is interior.
As shown in Figure 1, protruding horizontally up overhanging platform outward from the ship side of hull 3, fixing pipe 4 is fixed on overhanging platform and position
Immediately below drilling machine.Fixing pipe extends downward vertically from the bottom of overhanging platform, and vertically-guided pipe 5 is placed in fixing pipe 4 and it
The bottom extended downwardly is lower than the bottom of fixing pipe 4.Casing 6 is placed in vertically-guided pipe 5, is extended up to vertically downwards from managing
It is inserted into mud face, is cased with drilling rod 7 in casing 6,7 bottom of drilling rod is equipped with corer.
Fixed pipe outside diameter is 20~25cm, 12~20mm of wall thickness, 1.5~2.5m of length, and fixed bore, which is greater than, vertically leads
To 1~2cm of pipe outside diameter.Vertically-guided pipe is 7~9m of length, 8~12mm of wall thickness, as shown in Fig. 2, there is gear at vertically-guided tube top end
Plate, baffle wedge prevent vertically-guided pipe from falling off out of fixing pipe in fixing pipe nozzle.Vertically-guided bore is greater than sleeve outer
1~2cm.Casing wall thickness 6mm~10mm, casing use the form of more piece tube unit continued access to extend its total length.Such as Fig. 3 institute
Show, the head end and tail end of tube unit are respectively equipped with external screw thread and internal screw thread, for the spiral shell between upper and lower more piece tube unit
