    摘要： Apparatus including a digger for digging a trench to a predetermined level which is maintained by control apparatus responsive to a laser beam plane. The earth removed by the digger is directed into screening apparatus, and at least some of the fine particles therefrom are spread over the bottom of the trench to a predetermined depth. A roller unit follows the digger and presses a system of channels in the trench bottom. The coarser particles from the screening apparatus are then spread over the trench bottom and the channels. If desired, the apparatus may include means for directing a sealant over the surfaces of the channels before the coarse particles are directed thereover.

    摘要： A method of consolidating damp foundation soil, e.g., natural or synthetic clay or silt alone or mixed with sand, includes a number of cycles each including a dynamic force phase in which dynamic superimposed loads of at least 500 to 10,000 tons are applied to the soil to fluidize it, and a rest phase, possibly several days, during which the interstitial water escapes and the soil is restructured. Optimum parameters are ascertained by the use of a model testing rig comprising an expansible chamber to contain a sample of the soil, and means for applying static and dynamic pressure to the contents and measuring the relevant parameters.

    摘要： A method for consolidating impermeable soils. Mixes of binding materials are pressure injected into the subsoil through pipes alternately formed of blind wall sections and apertured wall sections, through the latter said binding mixes laterally pressing the soil and forming therein consolidation enlargements which are spaced apart from one another along the vertical axis of the guiding tube.
