摘要: Extensible shells and related methods for constructing a support pier are disclosed. An extensible shell can define an interior for holding granular construction material and define a first opening at a first end for receiving the granular construction material into the interior and a second opening at a second end. The extensible shell can be flexible such that the shell expands when granular construction material is compacted in the interior of the shell. A method may include positioning the extensible shell in the ground and filling at least a portion of the interior of the shell with the granular construction material. The granular construction material may be compacted in the interior of the extensible shell to form a support pier.

摘要: The disclosure discloses a high-performance liquefaction mitigation method forstone columns for protecting the existing buildings during earthquakes. Specifically, a small equipment is used to dig trenches in the soil around the existing building. Then, a spiral driller is used to drill a series of boreholes in the trenches according to the optimized borehole design. Next, two or three layers of optimized gravel material with high permeability are filled into the boreholes to work as the inverted layer. Finally, geotextile is arranged around the trench and the trench is filled with the optimized gravel. Compared with current liquefaction mitigation methods for existing buildings, the disclosure is suitable for liquefaction mitigation in large cities, and has the advantages of low disturbance to the overlaid building, simple construction process, high construction efficiency, low construction cost, long service life and the construction material could be easily obtained.

摘要: Soil inclusions (30) comprising an elongated, cured cementitious columnar body (72) are located within the soil (32) and include a tubular perforate structural reinforcement (56a, 56b) embedded within the body (72), with portions of the body exuded through the perforations (57) of the structural reinforcement (56a, 56b). The inclusions (30) are formed by driving a tubular mandrel (44) through vibratory means into the soil (32), with a flexible, tubular, perforate reinforcement (56a, 56b) about the exterior surface of the mandrel (44). When the mandrel (44) is fully driven, it is withdrawn, and simultaneously cementitious material (70) is injected into the mandrel (44). The material (70) exudes through the perforations (57) to complete the inclusion (30), which is deformation compliant. The inclusions may be installed in vertical or non-vertical orientations.

摘要: A mallet is described that has at least one cleft, in such a structure that the stress wave created during impact has longer travel way than the length of the mallet as measured along the impact line. This mallet induces longer-lasting and weaker stress wave(s) in the anvil as compared to a solid mallet having the same outer dimensions and more or less the same weight. The Cleft-Mallet increases the effectiveness of the strike, while decreasing the stresses in the anvil.
