摘要： This invention is detailing a construction method for a cast in-situ pile having an upper section with a larger diameter and at least one subsequent section with a smaller diameter, and a drilling device equipped with continuous flights which allows the construction of one pile having multiple diameters using the innovative construction method in a single continuous drilling phase while each drilling tool is penetrating through the soil in one pass.
The drilling tool according to the invention has a central hollow space that allows accommodation through it of at least one another smaller diameter drilling tool that can drill continuously and can be coupled by means of a coupling-decoupling device in a specific manner to the other drilling tool in order to act as a fixed assembly, at any given position in relation to the smaller drilling tool length and rotating position.

摘要： A method for the construction of composite under-reamed pile, including: implementing a jet grouting and agitation at a pre-designed position to form a composite cemented-soil foundation; constructing the pile hole with a drilling rig, during which bulb cavities are formed when the pile structure includes bulbs; cleaning the pile hole, lifting down a reinforcing cage, lowering a concrete pouring conduit to the pile hole, and lifting the pouring conduit while pouring the concrete; the hardened concrete becoming a pile stem in the pile hole and a bulb in the bulb cavity. Thus, this construction method can completely eliminate the hole collapse risk at the bulb cavity position during drilling; the combined structure of the bulb and the composite cemented-soil foundation can greatly improve the bearing capacity of pile foundation, significantly reduce the settlement risk and the cost of the pile foundation, as well as shorten construction period.

摘要： A woodpile connector has a tubular body defined by an open-end lower portion and an open-end upper portion. The upper portion and the lower portion are fixedly connected, at their free ends, to a separating plate, which is secured between an inner surface and an outer surface of the tubular body. The open ends of the connector body have beveled edges to facilitate compression of the wood being forced into the connector body. By aligning the connector portions in relation to the pile sections, while forcing the connector portions into the ends of the adjoining pile sections, alignment of the pile sections is achieved even when the pile sections do not have evenly cut connecting surfaces.

摘要： A reinforced-concrete column contains reinforcing cage and inserts made monolithic with concrete mix and comprises the upper bearing and lower foundation parts. The method of construction of the column includes operations of manufacture of the column reinforcing cage with inserts, placement of concrete in the non-removable casing in the project position in single- or multi-slit pit with the column making monolithic. The column reinforcing cage is loaded vertically into the pit, centered vertically, and the upper part is fixed from horizontal displacements, the lower foundation part of the column and the inner part of the non-removable casing with the closed-type casing in the upper bearing part of the column are made monolithic with concrete from down to top. After making monolithic, the soil base is widened and cemented via the process pipeline placed inside the reinforcing cage; the space between the non-removable casing and the pit walls in the upper bearing part is filled with granular material.

摘要： A method of constructing foundation piles provides improved hole stability and bearing characteristics. A boring a hole is initially formed by drilling. A horizontal pressure is then applied to the inner walls of the hole over a vertical portion of predetermined height until a desired degree of compression is attained. Horizontal pressure is then applied over a subsequent vertical portion of an inner circumferential surface of the hole vertically adjacent to a vertical portion pressed in a preceding step of applying horizontal pressure. The steps of compression are continued until a contiguous vertical expanse of the hole is compressed to a desired degree. Alternatively, the depth of the hole may be increased sequentially following a compression operation, and the subsequently formed hole depth then horizontally compressed. In a further embodiment, vertical pressure is applied over a circumferential annular surface area at a bottom of the hole, and also over a central circular area surrounded by, and adjacent to, the circumferential annular surface area.
