    摘要： METHOD AND APPARATUS FOR SUCTION DREDGING PARTICULATE MATERIAL SUCH AS SAND. A SUCTION PIPE IS INSERTED INTO A BODY OF SAND BELOW THE BOTTOM OF A BODY OF WATER TO WITHDRAW A WATER-SAND SUSPENSION HAVING A DESIRED CONCENTRATION OF SAND IN SUCH SUSPENSION. AT THE LOWER END OF THE PIPE, THE SAND IS DRAWN IN AT VERY HIGH CONCENTRATION AND AT SOME LEVEL ABOVE THIS POINT WATER IS SEPARATELY IN-

    TRODUCED AND THE DESIRED CONCENTRATION IS OBTAINED BY ADJUSTING THE LEVEL AT WHICH THE WATER IS INTRODUCED. THE CONCENTRATION OF THE RESULTING SUSPENSION IS MEASURED TO ENABLE THE LEVEL OF WATER INTRODUCTION TO BE ADJUSTED PROPERLY.

    摘要： The relatively hard layer of clay which covers an underwater body of sand is penetrated rapidly by forcing the lower end of a suction-dredging pipe assembly into the layer while drawing water through the pipe at a sufficiently rapid rate as to erode the clay and form a core of clay in the lower end of the pipe. This core may be removed either by crushing same so that the flowing water rapidly washes it away, or by periodically maintaining suction on the pipe to retain the core, withdrawing the pipe from the hole and expelling the core, whereafter the operation is repeated until the body of sand is reached.

    摘要： In the conventional method of loading a hold of a vessel with dredging spoil, in which a suspension of water and dredging spoil is admitted into the hold after the hold overflows until the required amount of dredging spoil is situated in the hold. Much dredging spoil flows into the outboard water. A more efficient filling operation is obtained when the suspension is deposited in a tube which is so kept in the hold that it is surrounded by the hold on all sides, and which is kept at such a depth in the hold that the bottom of the tube always remains above the level of the settled part of the spoil, while the tube penetrates into the liquid.

    摘要： In dredging sand, an inner pipe is movable longitudinally within an outer jacket so that the lower end of the inner pipe may be projected beyond the lower end of the jacket and retracted within the jacket. Suction is maintained on the inner pipe and water under pressure is supplied to the jacket so that, when retracted, the lower end of the inner pipe draws in a mixture of sand and water entering the lower end of the jacket to provide the desired suspension in the pipe. In intermediate positions, the lower end portion of the inner pipe blocks the lower end of the jacket but the lower end portion of the inner pipe is formed to communicate the lower end of the inner pipe with the water under pressure in the jacket.

    摘要： A method and apparatus for measuring the slurry concentration and velocity distribution in a pipeline wherein a first probe is used to determine the velocity at a predetermined position in the pipeline and a sample probe is then moved to the position and sampling rate adjusted until the velocity response to the two probes are equal. The local value of the velocity is obtained by dividing volume per unit of time of the sample by the cross-sectional area of the probe while the slurry concentration and particle size distribution are obtained by analysis.
