Cement mixing pile construction method
The invention provides a cement mixing pile construction method. The cement mixing pile construction method comprises the following steps: leveling a site; carrying out surveying and setting out, and determining a pile position; positioning and centering a stirrer; preparing mixed cement slurry: carrying out pre-stirring and sinking: spraying slurry, and performing stirring and lifting; repeatedly stirring; and enabling the mixed cement slurry to realize rapid setting through heating to form a cement mixing pile. According to the technical scheme, the lubricating liquid is injected into the underground soil body in the pre-stirring sinking stage, the lubricating liquid plays a role in lubricating and cooling a drill rod, abrasion of the drill rod is reduced, the service life of the drill rod is prolonged, the lubricating liquid further infiltrates the underground soil body, drilling of the drill rod is easier, the construction progress is accelerated, and the construction period is shortened; and heat conduction wires are mixed in the mixed cement slurry, the top face of the cement mixing pile is heated after initial setting forming of the cement mixing pile, the setting forming process of the cement mixing pile is accelerated, all components in the cement mixing pile are tightly connected and rapidly set to the expected strength, the construction period is shortened, and the construction efficiency is improved.
本发明提供了一种水泥搅拌桩施工方法，包括以下步骤：平整场地；测量放线，并确定桩位；使搅拌机就位对中；制备混合水泥料浆：预搅下沉：喷浆搅拌提升；重复搅拌；通过加热使混合水泥料浆快速凝结形成水泥搅拌桩。采用本发明的技术方案，通过在预搅下沉阶段向地下土体内注入润滑液，润滑液对钻杆起到润滑和冷却作用，减少了钻杆磨损，延长了钻杆使用寿命，润滑液还将地下土体浸润，使钻杆更容易钻进，加快了施工进度，缩短了施工工期，通过在混合水泥料浆内掺入导热丝，在水泥搅拌桩初凝成形后对其顶面进行加热，加快了水泥搅拌桩的凝固成形过程，使水泥搅拌桩内各组分紧密连接并快速凝固至预期强度，缩短了施工工期，提高了施工效率。
