Description

Engineering pile foundation pile casing Technical Field The application relates to an engineering pile foundation casing, and belongs to the technical field of constructional engineering. Background In the field of constructional engineering, a pile foundation is used as a core support form for guaranteeing the stability and safety of a building structure, and is widely applied to various large projects, and a pile casing in pile foundation construction is a key element for guaranteeing the smooth pushing and pile forming quality of construction. In actual engineering, different projects have various requirements on pile foundation specifications, and different requirements on the inner diameter and the height of the pile casing can be met in the same project due to factors such as geological differences, design changes and the like. The fixed specification of the traditional pile casing makes the traditional pile casing difficult to adapt to the complex and changeable construction scene, so that the applicability is greatly reduced. During construction, the unmatched inner diameter and height also influence construction safety and efficiency, such as the situations that the improper inner diameter can cause material waste and increased installation difficulty and a pile casing suitable for the pile diameter needs to be manufactured again, and the unmatched height can influence the protection range of the pile head during loading and easily cause the pile head splitting phenomenon during loading. Therefore, the engineering pile foundation casing with the inner diameter and the height capable of being flexibly adjusted is developed, and has important practical significance for improving the universality, the adaptability and the economy of pile foundation construction. Disclosure of utility model According to one aspect of the present application, an engineered pile foundation casing is provided that can be adjusted in height and inside diameter to suit different engineering scenarios. An engineering pile foundation casing, comprising: The cylinder body comprises at least 2 cylinder protection units, wherein adjacent cylinder protection units are spliced along the height direction of the cylinder body, so that the height direction of the cylinder body is adjusted; the pile casing unit comprises a pile casing part and an adjusting part, the pile casing part and the adjusting part are connected to form a cylindrical structure, and the connecting end of the pile casing part and the adjusting part moves circumferentially on the adjusting part so as to adjust the inner diameter of the pile casing unit; the pile casing part and the adjusting part are of semi-surrounding structures. Further, one end of the pile casing unit is provided with a plurality of clamping parts, the clamping parts extend outwards along the height direction of the pile casing unit, and the clamping parts are uniformly and circumferentially distributed at the end part of the pile casing unit; The other end of the pile casing unit is provided with a plurality of clamping grooves which are matched with the clamping parts.
