    摘要： The aim of this invention is to present a method in which holes (1) are drilled into the ground for the injection of highly expansive grouts (5), so that the subsoil is void filled and compacted and thus the liquefaction potential under earthquake and vibration forces are reduced.

    摘要： The present invention provides a head for injecting a fluid under pressure for breaking up the ground from a borehole and mounted at the end of a string of rods. The body of the drilling head has a bottom wall for mounting a mechanical drilling tool having a feed pipe, at least one injection nozzle, and duct-forming means for connecting the feed pipe with liquid at the inlet of said nozzle, the duct-forming means presenting a mean line having a radius of curvature that varies continuously, the right section of said duct-forming means decreasing regularly over at least half its length from its first end towards its second end. The injection head further comprises at least one pipe for feeding said mechanical tool, said pipe being connected at a first end to said duct-forming means and at a second end to a chamber disposed at the bottom end of said injection head and fitted with a controllable shutter member interposed between said chamber and the pipe for feeding said mechanical tool.

    摘要： Compacted granular or stone columns are constructed in soil to increase the load-bearing capacities of the native soil. The upper portion of the compacted granular column is provided with a rigid central core such that vertical loads imposed on the composite column are transferred to a deeper level on the compacted column where the column operates more efficiently. A probe is centrally penetrated downwardly into the compacted granular column, and the resulting cavity is filled with cementitious grout to form a solid core after hardening. The grout may be injected into the cavity so formed in the compacted column at the bottom of the probe as the probe is being withdrawn in predetermined quantities metered in synchronization with the rate of withdrawal of the probe from the core cavity.

    摘要： Consolidation construction for soft, unstable foundation for improving the bearing strength in order to fill earth thereon as in land reclaiming or to build structural construction thereon including dikes and roads. Examples of such unstable foundation requiring consolidation are: sea bottom with soft unsolid sedimentation heap as often referred to recently in Japan as HEDORO, muddy swamp land, layer of slimy industrial waste sludge of much water content and the like. Consolidation is effected on the spot by admixing hardening agent, such for instance as cement, with the slimy mud heap constituting the soft, unstable foundation. The construction is featured by a large number of consolidated walls juxtaposed one after another, each extending along the direction coinciding with the direction in which the maximum sliding, shearing rupture stress appears under the gravity load of the superstructure, namely the fill-soil or the edifice, built on the soft, unstable foundation improved by this consolidation construction; and ensures dynamically very stable consolidation effect, with quite large bearing strengths both for the vertical gravity load from the above and for the sliding, shearing rupture stress.
