Construction method of iron tower hole digging foundation
The invention relates to the technical field of building foundation construction, in particular to an iron tower hole digging foundation construction method which comprises the following steps: digging a foundation pit; a grouting channel in the vertical direction is excavated in the side wall of the foundation pit; the side face of the grouting channel communicates with the foundation pit. The at least two grouting channels are arranged in an array by taking the foundation pit as a center; a grouting pipe is pre-buried in the grouting channel; the upper end of the grouting pipe is used for feeding grout, and the lower part is used for discharging grout; mounting a retaining wall structure in the foundation pit; grouting holes are reserved in the side wall of the retaining wall structure; the grouting holes are communicated with the inner side and the outer side of the retaining wall structure; the mud jacking pipe is located on the outer side of the wall protecting structure. Concrete pouring is conducted in the retaining wall structure; after the poured concrete meets the preset requirement, pressure grouting treatment is conducted from bottom to top in a layering mode through a grouting pipe; and grouting treatment is conducted on the inner side of the retaining wall structure. The stability of the iron tower hole digging foundation is improved, the bearing capacity of the hole digging foundation is improved, the settling volume is reduced, and the construction cost is reduced.
本发明涉及建筑基础施工技术领域，尤其涉及一种铁塔挖孔基础的施工方法，其包括以下步骤：基坑掏挖；在基坑的侧壁挖掘竖直方向的灌浆通道；灌浆通道的侧面与基坑连通；至少两个灌浆通道以所述基坑为中心阵列设置；在灌浆通道内预埋压浆管；压浆管的上端用于进浆，下部用于出浆；在基坑内安装护壁结构；护壁结构的侧壁上预留有灌浆孔洞；灌浆孔洞连通护壁结构的内侧和护壁结构的外侧；压浆管位于护壁结构的外侧；对护壁结构内进行混凝土浇筑；浇筑的混凝土达到预定要求后，通过压浆管由下向上分层进行压力灌浆处理；对护壁结构的内侧进行灌浆处理。采用本发明提升铁塔挖孔基础的稳定性，增加挖孔基础承载力，减小沉降量，降低施工成本。
