Mixing pile process: prepare cement → put pile driver in place → drill hole (add water while drilling and put cement powder for mixing) → form pile → conduct light penetration inspection three days later to inspect the data of mixing pile: construction records The items submitted for inspection of mixing pile include cement, cement soil test pieces and reinforcement..
Pile foundation process Engineering pile (static pile pressing) process: joint review of drawings – pile location number – preparation of pile driver’s walking line diagram – preparation of pile foundation construction plan – pile driver mobilization – personnel mobilization – pipe pile and pile tip sunrise and material review – quality and technical disclosure – measurement and setting out (positioning and project baseline review) – commencement application report – pile testing – piling – pile foundation detection (bearing capacity: high strain, static load) – earthwork excavation – pile cutting (up to the design pile top height) -After earthwork excavation, the pile foundation shall be rechecked and the corresponding pile position deviation diagram shall be drawn – pile foundation inspection (integrity: small strain) – inspection If there is no Class III pile, the pile can be accepted, and if there is Class III pile, the pile shall be supplemented – after the inspection is qualified and the test report is issued – the pile foundation acceptance, measurement, setting out, application for inspection (baseline review), project baseline review form, commencement report (unit project), project commencement, Resumption report Form Commencement application report of unit project Commencement report (pile foundation sub divisional project) Commencement of project, Resumption report Form Commencement application report of pile foundation sub divisional project, pipe pile and pile tip mobilization: 1.
