Abstract

A jetting type embedded plough for paving composite hoses on a shallow sea comprises a plough body, a slipper, a jet pump, a valve, a flared opening, a lug, a sonar, a traction board, a ground breaker and a nozzle. A traction rope is arranged on the traction plate; the embedded plough is hoisted to the superior position of the embedded plough and then is lowered to be near to a mud surface; a diving jet pump is started, then a ship is started to advance, and simultaneously, a pipe placing system on a deck synchronously places pipes; and a ground breaking plate on the embedded plough is used for breaking the ground so as to prevent hard stones from scratching the nozzle. The jet pump of the jetting type embedded plough is placed on a water embedded plough instead of the construction ship, and a starting switch of a controlling pump is placed on the construction ship. When the embedded plough is used for paving the small-bore high-pressure steel belt composite hoses on the shallow sea, the composite hoses can be successfully paved 2 meters below the mud surface at the bottom of the sea, and can be embedded, so that sea pipelines can be prevented from wandering.

Description

A kind of injecting type that is used for shallow sea composite soft tube laying is buried plough underground

Technical field

The utility model relates to the innovation of a kind of ocean flexible pipe laying apparatus.

Background technology

Along with the appearance of ocean, domestic shallow sea composite soft tube, drawn and how the problem of composite soft tube laying has been launched discussion, generally all require to carry out pipe laying for the shallow sea flexible pipe and lay, to prevent that pipe is in the seabed drift.At present domestic shop cable machine at cable laying is more, aboard ship places but majority all is a water pump, buries the cable machine under water, between carry out transporting water by high-pressure rubber pipe.

Summary of the invention:

The technical problem that the utility model solves provides a kind of injecting type and buries plough underground, buries the used water jet pump of plough underground and is not placed on the construction boats and ships, buries underground on the plough and be placed on water, and the starting switch of control pump is placed on the construction boats and ships.

The utility model technology contents is, a kind ofly is used for the injecting type that the shallow sea composite soft tube lays and buries plough underground, comprises plough body, piston shoes, water jet pump, valve, horn mouth, hanger, sonar, drawing plate, break ground, nozzle.Pulling rope is installed above the drawing plate, to bury the plough lifting underground with loop wheel machine and bury upward position of plough underground, transfer near the mud face, start the diving water jet pump, the unlatching boats and ships move ahead, simultaneously the guard system of putting on the deck is put pipe synchronously, and the plate of burying underground on the plough that breaks ground is used for breaking ground, and prevents that hard stone from will bury the nozzle scratch on the plough body underground.

The beneficial effects of the utility model are, when using this device to carry out that the small-bore high pressure steel strip-plastic composite hose in shallow sea is marine to be laid, can effectively composite soft tube be laid on smoothly about the following 2m of seabed mud face, and bury underground, prevent extra large pipeline drift.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 2 buries the plough lateral view underground for the injecting type that the shallow sea composite soft tube is laid

Fig. 3 buries the plough vertical view underground for the injecting type that the shallow sea composite soft tube is laid

1-plough body wherein; The 2-piston shoes; The 3-water jet pump of diving under water; The 4-valve; The 5-horn mouth; The 6-hanger; The 7-sonar; The 8-drawing plate; The 9-plate that breaks ground; The 10-nozzle.

The specific embodiment:

As shown in Figure 1, when carrying out composite soft tube sea laying construction, pulling rope is installed above the drawing plate 8, by burying the hanger 6 on the plough underground, utilize loop wheel machine will bury the plough lifting underground, monitor by sonar 7, bury underground plough transfer to piston shoes 2 during mud, stop to transfer and bury plough underground, the plate of burying underground on the plough 9 that breaks ground is used for breaking ground, diving water jet pump 3 is installed on the piston shoes, transfer after in the sea, by diving water jet pump 3 seawater is sucked, behind motor rotation in the pump, seawater is changed into the high pressure sea water that has pressure, and with these high pressure sea waters, enter in the plough body 1 by the pipeline of burying underground on the plough, pass through the multichannel nozzle 10 on the plough body 1 again, eject, the mud in seabed is washed away grooving.Flexible pipe enters from horn mouth 5, through plough body 1, goes out from plough body 1 end, enters in the ditch of injection molding, and the final backfill of the mud that ejects is buried pipe underground on pipe.In order to improve the safety of laying, diving water jet pump 3 is provided with two, strengthens water spray pressure, is used for controlling injection flow with two valves 4 respectively.

Claims

1. an injecting type that is used for shallow sea composite soft tube laying is buried plough underground, by plough body, piston shoes, the diving water jet pump, valve, horn mouth, hanger, sonar, drawing plate, plate breaks ground, nozzle is formed, it is characterized in that, the plate of burying underground on the plough that breaks ground is used for breaking ground, prevent that hard stone from will bury the nozzle scratch on the plough body underground, the diving water jet pump is installed on the piston shoes, the diving water jet pump sucks seawater, behind motor rotation in the pump, seawater is changed into the high pressure sea water that has pressure, and these high pressure sea waters are entered in the plough body by the pipeline of burying underground on the plough, go out through the multichannel nozzle ejection on the plough body, the mud in seabed is washed away grooving, the diving water jet pump is provided with two, strengthen water spray pressure, respectively with two valves to control injection flow.
