Concrete cast-in-place pile of sludge foundation and construction method of concrete cast-in-place pile
The invention provides a concrete cast-in-place pile of a sludge foundation and a construction method of the concrete cast-in-place pile. The concrete cast-in-place pile comprises a first pile body, asecond pile body and a plurality of third pile bodies which are sequentially arranged from top to bottom, and the first pile body, the second pile body and the third pile bodies are of an integratedstructure; the first pile body of the cylinder structure and the second pile body of the cylinder structure are coaxially arranged, the outer diameter of the first pile body is the same as that of thesecond pile body, the plurality of third pile bodies are arranged at the bottom of the second pile body in the axis direction of the second pile body in an extending mode, and the outer diameter of each third pile body is smaller than that of the second pile body. The method can effectively solve the problem of pile breakage in the cast-in-place concrete pile construction process under the sludgefoundation environment condition, and construction safety is guaranteed.
本发明提出了一种淤泥质地基的混凝土灌注桩及其施工方法，混凝土灌注桩包括自上而下依次设置的第一桩体、第二桩体和多个第三桩体，第一桩体、第二桩体和第三桩体为一体式结构；圆柱体结构的第一桩体与圆柱体结构的第二桩体同轴设置、且第一桩体和第二桩体的外径相同，多个第三桩体延第二桩体轴线方向延伸的设置在第二桩体的底部，第三桩体的外径小于第二桩体的外径；本发明能有效解决在淤泥质地基环境条件下混凝土灌注桩施工过程中的断桩问题，保证了施工安全。
