Description
Technical field
The present invention relates to a kind of submarine pipeline buried depth construction secondary trenches molding machine, especially a kind of submarine pipeline trench digging
Machine mud-suction nozzle.
Background technology
Buriing work construction technology after seabed large-diameter steel pipe usually first applies（First pipeline laying on sea bed face, then use water
Lower fluting apparatus outputs groove along pipeline, and pipeline is sunk to by dead weight in groove）, according to maritime goal, state
Interior submarine pipeline buried depth tube top earthing ≮ 2m reaches φ 1420, submarine trench according to data check country seabed bore maximum pipeline
Groove depth reaches 3.42m.The equipment fluting principle of buried depth of pipeline be all often with the dilute seabed soil of high pressure water flushing, then soil from
It is sucked out in groove.
1st, since pipe diameter is bigger, groove is deeper, and the amount of breaking ground and suction mud amount are consequently increased, so slotting under underwater boiling water
The fluting of equipment slows.
Once the 2, fluting slows along with bigger pipeline, bending radius is bigger, and self weight of pipeline sinks to trench bottom
Plate distance is longer, and pipeline is in time for sinking to channel bottom not yet, and molding groove is according to according to sea situation and soil property
Situation is different, and groove returns what and landslide situation will be more serious, and will generate pipeline can not just sink to trench bottom.
3rd, the bigger groove landslide of groove depth is more serious, and mud-suction nozzle is easy to solidifying soil burial of being caved in, and seabed rubbish
Rubbish is more also easily to block mud-suction nozzle, and just the mud in groove can not be sucked out, and the row of also needing to diver carries out underwater after blocking
Blockage problem is removed, the interior cleaning blockage problem of groove is dangerous big again by diver, and the time is long.
Will be often long there are the construction time in the construction process according to above-mentioned 3 points, operating efficiency is low, and seabed is inhaled
Mud mouth is once to block cleaning inconvenient, the problems such as influencing buried depth of pipeline.
Invention content
In order to overcome the above-mentioned deficiency of existing mud-suction nozzle, the present invention provides a kind of submarine pipeline ditching machine mud-suction nozzle, the suction
Mud mouth is not only sturdy and durable, not damaged, and easily can quickly handle blockage problem, improves the molding construction efficiency of groove,
The soil that can be quickly sucked out in groove improves construction efficiency and safety.
The technical solution adopted by the present invention to solve the technical problems is：A kind of submarine pipeline ditching machine mud-suction nozzle, including
Mud-suction nozzle steel pipe inhales outsourcing seals successively from top to bottom below the mud mouth of mud main pipeline gas cabin and water tank room, the gas
Cabin connects pressure-air delivery pipe, and the mud-suction nozzle steel pipe tube wall upper edge perimeter positioned at gas cabin is evenly arranged multiple ventholes,
It sprays high pressure gas by venthole and realizes and inhale mud；The water tank room connects high-pressure water pipe, the water on the outside of mud-suction nozzle steel pipe
Cabin bottom is uniformly distributed there are four boron carbide nozzle, and boron carbide nozzle water outlet direction is opposite with the direction that soil is sucked out.
The outlet hole number is 100, a diameter of φ 5mm of venthole, and in 45 ° of inclinations.
The water tank room is 2.0Mpa by the pressure of high pressure water that boron carbide nozzle projects.
When mud suction mouth is buried in groove landslide, four boron carbide nozzles project high pressure water and landslide soil are broken up,
Make mud-suction nozzle working properly.
The invention has the advantages that the mud-suction nozzle is not only sturdy and durable, it is not damaged, and easily quickly can clearly inhale
Mud mouth buries blockage problem, improves construction efficiency and the safety of buried depth of pipeline.
Description of the drawings
Fig. 1 is the submarine pipeline ditching machine mud-suction nozzle structural main section view of the present invention；
The submarine pipeline ditching machine mud-suction nozzle structure that Fig. 2 is the present invention is bowed sectional view.
Specific embodiment
Invention is further illustrated with reference to the accompanying drawings and examples.
Such as Fig. 1, shown in 2, a kind of submarine pipeline ditching machine mud-suction nozzle, including mud-suction nozzle steel pipe 1, gas cabin 2, water tank room 3
Deng.Outsourcing seals successively from top to bottom below the mud mouth of mud main pipeline 1 gas cabin 2 and water tank room 3, gas cabin 1 is inhaled to connect
Pressure-air delivery pipe, the tube wall upper edge perimeter positioned at the mud-suction nozzle steel pipe 1 in gas cabin 2 are evenly arranged multiple ventholes 5, pass through
Venthole 5, which sprays high pressure gas and realizes, inhales mud；Water tank room 3 connects high-pressure water pipe, positioned at the water tank room 3 in 1 outside of mud-suction nozzle steel pipe
Bottom is uniformly distributed there are four boron carbide nozzle 4, and the water outlet of boron carbide nozzle 4 direction is opposite with the direction that soil is sucked out.Venthole 5
Quantity is 100,5 a diameter of φ 5mm of venthole, and in 45 ° of inclinations.The high pressure that water tank room 3 is projected by boron carbide nozzle 4
The pressure of water is 2.0Mpa.
When mud suction mouth is buried in groove landslide, four boron carbide nozzles 4 project high pressure water and landslide soil are broken up, and make suction
Mud mouth is working properly；If mud-suction nozzle is blocked by seabed rubbish, multiple switching high pressure water washes out rubbish, convenient and efficient.
Perimeter is evenly arranged 100 45 ° of φ 5mm ventholes outlet 5 on the tube wall of mud-suction nozzle steel pipe 1；It is inhaled by air
Mud principle inputs in gas cabin enough air on workboat and is allowed to the soil in groove that sea is sucked out；Water tank room 3 is collection
Middle 2.0Mpa high pressure waters, then 4 φ 8mm boron carbides nozzles 4 is divided to be discharged, direction that the direction of water outlet is sucked out with soil on the contrary,
Mud-suction nozzle steel pipe 1 is stainless-steel pipe.Gas cabin 2, water tank room 3 are made of 6 material of main part of steel plate.
The present invention is made of welding manner.Material stainless steel material, it is anticorrosive, it is suitable for using in the seawater.Gas chamber
For independent air chamber, and special setting air inlet and venthole respectively.
Flanged joint is responsible for, then connect supply air line and water supply pipe with spoil disposal when mud-suction nozzle is installed.Trench digging is set first
Standby start is started to work, and starts high pressure water, first the soil on mud-suction nozzle side is broken up, and restarts air feed equipment, it is former that air inhales mud
Sea is sucked out in soil in groove by reason, and when encountering groove landslide and being drawn onto rubbish blocking mud-suction nozzle, high-pressure hydraulic is realized at any time
Blockage problem is solved in time.
