摘要： A concrete variable cross-section prefabricated square pile, comprising pile bodies of large cross-section sections and small cross-section sections alternately arranged along a longitudinal direction. Lateral transition surfaces are formed between side surfaces of the large cross-section sections and adjacent small cross-section sections; at least part of the lateral transition surfaces have a front edge and/or a rear edge that are offset from a vertical direction in a lateral projection, and a vertical projection of an intersection line between the lateral transition surface and a first horizontal plane is located outside a vertical projection of an intersection line between the lateral transition surface and a second horizontal plane; the first horizontal plane is a horizontal plane located above in any two horizontal planes, and the second horizontal plane is a horizontal plane located below in any two horizontal planes; one or both side surfaces of the small cross-section section are perpendicular to the bottom surface of the small cross-section section or are laterally inclined by a set angle. According to the prefabricated pile, the phenomenon that the middle section is easy to damage can be avoided, the breakage rate of the variable cross-section prefabricated square pile is reduced, and the product quality of the variable cross-section prefabricated square pile is more stable and reliable.

摘要： The invention relates to building bearing reinforced concrete elements. The novelty of the method for mounting reinforced concrete column and of the design structure of the column mounted in a ground excavation lies in that said column is embodied within a non extractable timbering (2) in a one or multi-slotted ground excavation. The projection of the geometric centre of the cross section of said non-extractable timbering is superimposed with the projection of the geometric centre of the cross section on the lower part of a reinforcement cage (6). The sizes of the branches of the lower part of said reinforcement cage and the ground excavation sizes are defined according to certain dependencies. The aim of said invention is to improve the accuracy for vertical mounting a support foundation and bearing elements of a building and to make it possible to build simultaneously structure upwards and downwards below a ground level.

摘要： Foundation systems and methods using in-situ shaped pile-anchors that are particularly adapted for use in aquatic environments. The shaped pile-anchor of the invented foundation includes a concrete filled tubular metal casing, the bottom end of which is positioned at a predetermined depth in the ground (e.g., aquatic-floor soil) and the top end of which protrudes above the water or soil surface. Concrete fills the inside the metal casing, substantially all the way to the top end of the casing, forming an upper portion of a concrete column. The lower portion of the concrete column extends down below the bottom end of the metal casing and further into the ground. The lower portion is shaped to have a cross-section greater than the cross-section of the upper portion, which equals to the inner diameter of the tubular metal casing. A platform is coupled to one of more of the shaped pile-anchors to support a structure above.

摘要： The present invention provides a method for the construction of composite under-reamed pile, comprising: 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 comprises 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.
