The invention relates to a hydraulic mechanic 26 - with an end portion of a waste

intended for subsea pipeline 20 containing a descending

soil excavation. under the water a rotary nozzle 40 with the purpose of the invention is to raise the tip 41.

suction dredger performance yesLift and lower end section

by increasing the dewatering of the soil. 5 of the suction pipe 1 and the end

The drawing shows schematically the ground part 40 of the discharge pipeline 20; a polar-projectile projectile is driven by two cable lobes; The projectile projectile contains a suction dock 42.

with the receiving chamber 3, the receiving nozzle on the horizontal conveyor 44.

com 4, an ejector 5 with a discharge nozzle-Operation of a suction suction projectile 6 and a separation chamber 7, is performed as follows,

in the form of a transition diffuser

into the confuser, with the outlet pipe 8, the main 7 and the additional 16 sectioned perforated pipe 9 and the pipe branch chambers and the discharge pipe 20

com 10, connected to the groundwater, 15 flows through two streams. The first stream is sate 2. On the pressured Ibirats subsoil pipeline from the reservoir along the suction

the camera 12 is located with the receiving pipe-pipe 1 by a ground pump 2, and

room 13, the ejector 14 with a pressure pipe-second - through the suction pipe

com 15 and additional separator 30 water pump 29.

camera 16, made in the form of diffuse. In the process of operation, both flows of the mixture passing into the confuser are discharged from the receiving chamber 3, and then

the pipe 17, the perforated pipe are separated in the chamber 7. One stream with

The separating chamber 7 pressure pat-and the inlet 13 is directed

The wheel 6 is attached to the pressure pipe in the additional separation chamber 16.

the wire 27 with the shut-off valve 28 of the water 30; Both flows in the chamber 12 are mixed,

the pump 29 with the suction pipe is then separated in the chamber 16. Wherein
