Loess heavy hill terrain square pile hole-forming construction method and construction device
The invention relates to the technical field of pile foundation construction, in particular to a loess heavy hill terrain square pile hole forming construction method and device. Comprising the following steps that S1, a guide cylinder meeting the requirement is manufactured according to a to-be-constructed square pile pore-forming structure; s2, the manufactured guide cylinder is buried in the construction position of the square pile; s3, drilling and coring are conducted in the guide cylinder through a rotary drill; s4, after drilling and core drawing operation in the guide cylinder is completed, a pin plate is loaded by the pile driver to conduct inserting, beating and edge cutting on the inner wall of the guide cylinder; s5, sediment cleaning is conducted on the hole bottom of the inner side of the guide cylinder; and S6, the formed hole is rechecked, if the design requirement is not met, operation is conducted again according to the steps S3-S5 till the formed hole meets the design requirement, and square pile hole forming construction is completed. The method for conducting square pile hole forming construction on the loess heavy hill terrain is very simple, holes can be rapidly formed through simple equipment, the field operation capacity is high, the construction period occupied by multi-hole flow production is short, and the field practical operation efficiency is effectively improved.
本发明涉及桩基施工技术领域，具体地指一种黄土重丘地形方桩成孔施工方法及施工装置。包括以下步骤：S1、根据待施工方桩成孔结构制作符合要求的引筒；S2、将制作好的引筒埋设至方桩施工位置；S3、利用旋挖钻在引筒内进行钻孔掏芯；S4、待完成引筒内的钻孔掏芯作业后，打桩机装载插销板对引筒内壁进行插打削边；S5、对引筒内侧孔底进行沉渣清理；S6、对成孔进行复核，若不满足设计要求，则重新按照步骤S3～S5进行操作直至成孔满足设计要求，完成方桩成孔施工。本申请在黄土重丘地形进行方桩成孔施工的方法非常的简单，利用简单设备即可快速成孔，现场操作能力强，多孔流水作业占用工期短，有效提高现场实操工效。
