Abstract

The invention relates to a construction method for anchoring, separating and positioning a submarine hammer body of an anchor body. The construction method comprises the steps as follows: a windlass is released and goes into a neutral position, so as to enable the hammer body and the anchor body on the windlass to be in a an exile state; an upper solenoid valve at the upper end of the hammer body is opened immediately, and gas injection is performed by a high-pressure power assisting jet head by utilizing the high-pressure gas of the hammer body, so as to enable the hammer body and the anchor body to be fast inserted into a sea bed; after the anchor body is inserted into the sea bed, a vibroflotation mechanism of the hammer body and a high-pressure spout of the anchor body are opened, a gas-supply solenoid valve of the hammer body is opened, and the high-pressure spout of the anchor body gets into a high-pressure gas injection state; and after the anchor body enters the sediment layer of the sea bed to the required depth, the hammer body is pulled by the windlass so as to release a locking and separating mechanism for the hammer body and the anchor body, the anchor body is inserted into the sea bed, and the hammer body is pulled out of the sea for reuse. The construction method is simple and convenient to operate, can finish marine anchoring, separating and positioning of the hammer body very well, fills a gap in the domestic and foreign anchoring and positioning technology, and has very high popularization and utility values.

Description

Anchor body slips into the hammer body anchoring separation in seabed and the construction of location

Technical field

the present invention relates to a kind of construction in the fixing seabed of anchor body in ocean operation, especially a kind of anchor body slips into the hammer body anchoring separation in seabed and the construction of location.

Background technology

at present, ocean exploitation is just in the ascendant, the wherein location of cage culture, offshore platform location and the afloat location of buoyancy aid trestle of diposits of petroleum exploitation, invariably need the construction of hammer body anchor and position, under current engineering technology level, the application of the anchor and position technology of extra large lower hammer and universal at home and abroad or a very large blank, still need to drop into larger manpower and materials and develop.

Summary of the invention

in order to solve the problem that better realizes hammer body anchor and position in current Offshore development, the invention provides a kind of anchor body and slip into the hammer body anchoring separation in seabed and the construction of location, this construction method is easy and simple to handle, construction is quick, reliable, Yi Hang, can well complete marine hammer body anchoring and separate and locate.

the technical solution adopted for the present invention to solve the technical problems is:

(1) open winch and enter neutral gear, make hammer body, anchor body on winch enter the state of banishing, enter fast sea;

(2) open immediately the upper electromagnetic valve of hammer body upper end, utilize the high pressure gas of hammer body itself to carry out high pressure power-assisted shower nozzle jet, by jet antagonistic force, make in hammer body and anchor body quick insertion sea bed;

(3) anchor body inserts after sea bed, open the high pressure spout of shake punch mechanism and the anchor body of hammer body, the punch mechanism that shakes comprises axial vibration mechanism and lateral vibration mechanism, there is downward impulsive force and the vibration reaming power to surrounding, when this masterpiece is used for hammer body, pass to anchor body, make hammer body and anchor body downwards when percussive drilling creeps into, vibrate reaming to surrounding, more creep into depths to sea bed, simultaneously, open the gas supply electromagnetic valve of hammer body, enter high pressure gas blowout state by the high pressure spout of anchor body, make hammer body, anchor body and soft silt around upwards erupt and scrub silt along the reaming soft formation of hammer body and anchor body, to reduce hammer body, the resistance that the flank of anchor body and anchor body creeps into downwards, accelerate the speed that anchor body creeps into downwards,

(4) enter after the degree of depth of sea bed silt layer requirement at anchor body, pull hammer body with winch, can remove the locking separation device of hammer body and anchor body, impel hammer body to separate with anchor body, anchor body is inserted in sea bed; Hammer body pulls out sea by winch and reuses, and utilizes anchor body connection cord can reach the sea carrier object of location fast; When the degree of depth of creeping into sea bed when anchor body reaches 5m, its inclination pulling force can reach 50T, when the degree of depth of creeping into sea bed when anchor body reaches 10m, more than its inclination pulling force can reach 100T, its particular case is determined according to the consolidation degree of mud bed, and in addition, the angle of its pulling force is also the key factor that affects pulling force size.

the invention has the beneficial effects as follows, this construction method is easy and simple to handle, and quick when construction, reliable, Yi Hang can well complete marine hammer body anchoring and separate and locate, and have filled up the one blank of domestic and international anchor and position technology, have very large popularization practical value.

Brief description of the drawings

below in conjunction with drawings and Examples, the invention will be further described.

fig. 1 is structural principle schematic diagram of the present invention.

in Fig. 1,1. hammer body connection cable, 2. high pressure power-assisted shower nozzle, 3. anchor body connection cord, 4. goes up jet pipe, 5. guide pipe, the punch mechanism that 6. shakes, 7. high-pressure air pipe, 8. hammer body, 9. locking separation device, 10. flank, 11. anchor bodies, 12. high pressure spouts, 13. sea beds.

Detailed description of the invention

open winch and enter neutral gear, make hammer body 8, anchor body 11 on winch enter the state of banishing, enter fast sea;

(2) open immediately the upper electromagnetic valve of hammer body 8 upper ends, utilize the high pressure gas of hammer body 8 itself to carry out high pressure power-assisted shower nozzle 2 jet, by jet antagonistic force, make in hammer body 8 and anchor body 11 quick insertion sea beds 13;

(3) anchor body 11 inserts after sea bed 13, open the high pressure spout 12 of shake punch mechanism 6 and the anchor body 11 of hammer body 8, the punch mechanism 6 that shakes comprises axial vibration mechanism and lateral vibration mechanism, there is downward impulsive force and the vibration reaming power to surrounding, this masterpiece is for hammer body 8 time, pass to anchor body 11, make hammer body 8 and anchor body 11 downwards when percussive drilling creeps into, vibrate reaming to surrounding, more creep into depths to sea bed, simultaneously, open the gas supply electromagnetic valve of hammer body 8, enter high pressure gas blowout state by the high pressure spout 12 of anchor body 11, make hammer body 8, anchor body 11 and soft silt around upwards erupt and scrub silt along the reaming soft formation of hammer body 8 and anchor body 11, to reduce hammer body 8, the resistance that the flank 10 of anchor body 11 and anchor body 11 creeps into downwards, accelerate the speed that anchor body 11 creeps into downwards,

(4) enter after the degree of depth of sea bed silt layer requirement at anchor body 11, pull hammer body 8 with winch, can remove the locking separation device 9 of hammer body 8 and anchor body 11, impel hammer body 8 to separate with anchor body 11, anchor body 11 is inserted in sea bed 13; Hammer body 8 pulls out sea by winch and reuses, and utilizes anchor body connection cord 3 can reach the sea carrier object of location fast; When the degree of depth of creeping into sea bed 13 when anchor body 11 reaches 5m, its inclination pulling force can reach 50T, when the degree of depth of creeping into sea bed 13 when anchor body 11 reaches 10m, more than its inclination pulling force can reach 100T, its particular case is determined according to the consolidation degree of mud bed, in addition, the angle of its pulling force is also the key factor that affects pulling force size.
