摘要： The present invention provides a tool for forming an underground cast-in-situ pile having an enlarged base, the tool comprising: a first pile-forming member having a first base- forming member; a second pile-forming member having a second base-forming member, the pile-forming members extending collinearly and being movable in a longitudinal direction relative to one another between: a digging state wherein the base- forming members are proximate to one another so that the pile-forming members can be driven underground; and a base-forming state wherein the base-forming members are spaced from one another so as to form an underground void between the first and second base-forming members, the void being tillable with a flowable fill to form the enlarged base of the underground cast-in-situ pile; and jack screw means, rotation of which causes relative longitudinal movement between the pile-forming members.

摘要： A grouting module may include a lower surface configured for connection to a screw pile component, an upper surface configured for connection to an upper hollow pile shaft, a body disposed between the upper surface and the lower surface, and an axial bore through the upper surface and at least a portion of the body. The body may include a flange configured to create an annular space around the upper adapter and one or more flow injection conduits configured for injecting grout received from the upper hollow pile shaft through the axial bore extension into the annular space while the pile is advanced downward into a substrate. Once the final pile tip elevation is reached, the pile extensions above the grouting module are counter- rotated slightly to realign the ports in the grouting module from side to bottom discharge and allow post-grouting of the lead pile extension.

摘要： This invention deals with a device and a method for an improved concrete pile casting in swelling soils by substantially lowering or eliminating heave forces created in active soils from affecting said piles by surrounding selectable parts of the pile by an easily deformable material for lowering the horizontal and the vertical soil movement effect, and by providing a low friction surface for further lowering vertical forces effect. This inventive device and method further facilitates subsequent operations by permitting an easy and seamless casting of coloumns and by ensuring a clean and smooth pile surface for a better adhesion of new concrete to an old one, as well as preventing cement dough sepage to surrounding soil and concrete segregation.

摘要： The invention relates to a method and an arrangement for concreting vertical shafts having a depth of e.g. 500 m or more. The concrete is conveyed to a low-lying application location (20) in the shaft by means of a concrete column that is situated in a downpipe (30). The aim of the invention is to guarantee demixing- and destruction-free concrete work. The concrete is removed in portions from the succeeding concrete column on the output end of the downpipe (30), is separated from the concrete column and depressurised and is subsequently conveyed to the application location.

摘要： A boom structure comprises a skirt (1) of impervious fabric, elongated floating means (2) in the form of pipes, and spacers (3) which are attached to the floating means and to the upper and lower edges (6, 8) of the skirt for keeping the skirt extended. The floating means (2) are constituted by two adjacent plastic pipes held together by lashings (5). The spacers are constituted by short pieces of pipe (3), also of plastic material, with the axial direction transversely of the longitudinal direction of the boom. The spacers are attached to the floating means (2) by means of the same lashings (5), which may be constituted by belts provided with buckles. The supporting structure of the boom consisting of the lashed pipes (2) and pieces of pipe (3) give the boom good sideways stability and also sufficient flexibility in the vertical plane.
