Method and device for burying a conduit under water
First Claim
1. A method for use of a penetrating body having a leading edge and an inclined ground contacting surface extending upwardly therefrom, into a porous ground material with pores being at least partially filled with water, said method comprising the steps of applying a driving force to said penetrating body in the direction of penetration, and discharging from said penetrating body at least one flow of gas to said inclined surface so as to facilitate the penetration of the body, the gas having a pressure adapted to exceed the pressure of the surrounding environment.

Abstract
A method for the penetration of a body (8), having a leading edge (21) and an inclined ground contacting surface (C, D, E) extending upwardly therefrom, into a porous ground material, the pores of the ground material being at least partially filled with water. The method comprises applying a driving force to the penetrating body in the direction of penetration, and discharging from the penetrating body (8) at least one flow of high-pressure gas to the inclined surface so as to facilitate the penetration of the body. Moreover, a penetrating body (8) and a plough assembly both of which can be used in the method. The method and equipment may e.g. be used for embedding drain tubes, pipes, cables or similar objects into a ground material also at a relatively great depth larger than 100 cm. Moreover, the embedding can be performed by employing a relatively high speed and can be performed at a relatively low energy consumption.

- 14. A body for penetrating into a porous ground material and comprising a leading edge and an inclined ground contacting surface extending upwardly therefrom, means for receiving a driving force so as to cause the penetration, means for supplying a pressurized gas to a cavity defined within the body, and gas discharging means communicating with the cavity for discharging the pressurized gas to at least one opening defined in the ground contacting surface and into the ground material surrounding the body so as to facilitate the penetration.
