Construction method of cast-in-situ bored pile
The invention discloses a construction method of a cast-in-situ bored pile. The construction method comprises the following steps of construction preparation; positioning a cast-in-situ bored pile hole and embedding a pile casing; preparing slurry; a drilling machine is in place; trial hole forming, hole drilling and hole cleaning; discharging slurry and muck; manufacturing a reinforcement cage and a latticed column; lowering and mounting the reinforcement cage and the latticed column; test splicing of the conduit and air tightness test; underwater concrete is poured; and pile hole backfilling. The method is easy and convenient to construct and high in stability, the hole forming problem in a complex geological area in engineering can be solved, the construction quality of the cast-in-situ bored pile can be guaranteed, and the purposes of reducing the construction cost and shortening the construction period can be achieved.
本发明公开了一种钻孔灌注桩的施工方法，包括以下步骤：施工准备；钻孔灌注桩孔定位及护筒埋设；泥浆制备；钻机就位；试成孔、钻孔及清孔；泥浆、渣土的排放；钢筋笼及格构柱制作；钢筋笼及格构柱下放安装；导管试拼及气密性试验；灌注水下混凝土；桩孔回填。本发明施工简便，稳定性高，可解决工程中复杂地质区域成孔问题，能够保证钻孔灌注桩的施工质量，且能达到既降低施工成本又节约工期的目的。
