Foundation pit foundation treatment process and rotary drilling machine suitable for same
The invention discloses a foundation pit foundation treatment process and a rotary drilling machine suitable for the foundation pit foundation treatment process, and relates to the technical field of foundation construction. S2, pile casing burying and hole guiding; s3, pore forming; and S4, hole cleaning is conducted, specifically, after hole forming of the rotary drilling machine is finished, a gravel pile machine is provided with a vibroflot for hole cleaning, and the vibroflot is continuously lifted and sunk till the hole is reversed out of the hole and slurry becomes thin. S5, pile manufacturing is conducted, specifically, the density of filler in the pile casing is controlled by continuously filling the hole with the filler, and when the certain density is reached, filler is stopped, and the pile casing is pulled up; and S6, quality inspection and acceptance. By using the specific rotary drilling machine and replacing the tool bit, the foundation of the foundation pit is not prone to collapse.
本申请公开了一种基坑地基处理工艺及适用于该工艺的旋挖机，涉及地基施工技术领域，包括以下步骤S1、桩位测量放样；S2、护筒埋设及引孔；S3、造孔；S4、清孔：旋挖机造孔结束后，采用碎石桩机配备振冲器进行清孔，通过连续上提、下沉振冲器，直至孔口反出泥浆变稀。S5、制桩：通过不断向孔内填料，控制护筒内填料的密度，当达到一定的密度时，停止填料并拔起护筒；S6、质量检查与验收。本申请通过使用特定的旋挖机，并且通过更换刀头的方式，使得基坑地基不容易出现塌陷的情况。
