Construction method of 610 full pile casing bored pile in deep sand layer
The invention discloses a construction method of a 610 full pile casing bored pile in a deep sand layer, which specifically comprises the following steps of geological drilling before construction, construction preparation, survey setting-out, drilling, hole cleaning, I-shaped steel placing, grouting and pile foundation detection. The drilling comprises the steps of steel casing machining, drilling machine in-place, soil layer drilling, deep sand layer drilling, rock layer drilling and perpendicularity detection. The construction method is suitable for pile foundation construction under complex and weak geological conditions, especially municipal pile foundation engineering with dense buildings, narrow construction site, limited clearance and high environmental protection requirements under deep and thick sand layer geological conditions, and it is guaranteed that the cement paste is lost in the deep and thick sand layer geology without pulling out the steel sleeve in the grouting process; under the geological condition of a sand layer, an environment-friendly drill bit is adopted to drill and form a hole with a steel casing, slurry wall protection is not needed, the influence on the surrounding environment in the construction process is small, the monitoring settlement of the surrounding earth surface is small, and the environment-friendly performance is good.
本发明公开了一种610全护筒钻孔桩在深厚砂层中的施工工法，具体包括如下步骤：工前地质钻探→施工准备→测量放样→钻孔→清孔→安放工字钢→注浆→桩基检测，钻孔包括钢护筒加工、钻机就位、土层钻孔、深厚砂层钻孔、岩层钻孔和垂直度检测。本发明适用于复杂软弱地质条件下的桩基施工，特别是深厚砂层地质条件下的建筑密集、施工场地狭小、净空受限、环保要求高的市政桩基工程，在注浆过程中不拔除钢套筒来保证实现水泥浆在深厚砂层地质中的流失，节约了大量水泥浆的材料费用及注浆时的人工机械成本，在砂层地质条件下，采用环保钻头带钢护筒钻进成孔，无需泥浆护壁，施工过程对周边环境影响少，周边地表监测沉降小，环保性能好。
