Rotary excavating cast-in-place pile construction technology and system
The invention discloses a rotary excavating cast-in-place pile construction technology. The rotary excavating cast-in-place pile construction technology combines a high-sulfur-resistant concrete technology and a steel casing hole-forming technology on the basis of a traditional rotary excavating cast-in-place pile process through operation steps which are sequentially implemented, the problems that mud protection walls cannot be adopted in a sludge stratum, precast piles are not suitable to be adopted under the high-corrosion geological condition, and rotary excavating cast-in-place pile bodies are difficult to form are effectively solved, meanwhile, the high-sulfur-resistant concrete construction technology is adopted, the construction benefit can be effectively improved, the adopted steel pile casing hole forming technology has the obvious effect on the pile body concrete forming quality, the pile body quality problems such as hole collapse and necking down are basically eliminated, the feasibility of pile foundation construction under the strongly corrosive soft geological conditions of a coastal area is ensured, and the pile foundation construction quality and structural strength under the strongly corrosive soft geological conditions of the coastal area and the like are effectively ensured.
本发明公开了一种旋挖灌注桩施工工艺，其通过依次实施的各操作步骤，在传统的旋挖灌注桩工艺基础上，结合高抗硫混凝土技术和钢护筒成孔技术，有效的解决了淤泥质地层中无法采用泥浆护壁、强腐蚀性地质条件下不宜采用预制桩、旋挖灌注桩桩身成型困难等问题，同时采用高抗硫混凝土施工技术亦可有效提高施工效益，采用的钢护筒成孔工艺对桩身混凝土成型质量效果明显，基本消除塌孔、缩颈等桩身质量问题，确保在滨海地区强腐蚀性软弱地质条件下桩基施工的可行性，并有效保证了滨海地区等强腐蚀形软弱地质条件下的桩基础施工质量和结构强度。
