Immersed tube and cast-in-place pile construction method of immersed tube
The invention relates to the field of cast-in-place pile construction, in particular to an immersed tube and a cast-in-place pile construction method of the immersed tube, the immersed tube comprises a plurality of vertically stacked assembly tube bodies, in every two vertically adjacent assembly tube bodies, a jacking groove is vertically formed in the outer side wall of the assembly tube body with the higher height, and an inserting groove is formed in the assembly tube body with the lower height; the bottom of the assembly pipe body at the high position is matched with the assembly pipe body at the low position in an inserted connection mode through the inserted connection groove, and the assembly pipe body at the low position is in threaded connection with a fastening bolt abutting against the interior of the jacking groove. A proper number of splicing pipe bodies are selected, and the multiple splicing pipe bodies are assembled into the whole immersed pipe through insertion connection of every two adjacent splicing pipe bodies and cooperation of fastening bolts; a vibratory hammer is installed at the top of the immersed tube to hammer the immersed tube to compact surrounding soil, and after the immersed tube is driven into the designed depth, concrete is poured into the immersed tube from a funnel at the top of the immersed tube. The immersed tube has the advantages that the overall length of the immersed tube is flexibly adjusted, and then the immersed tube is suitable for pouring cast-in-place piles with different depths.
本申请涉及灌注桩施工领域，尤其是涉及一种沉管及该沉管的灌注桩施工方法，包括多个竖向堆叠的拼装管体，竖向相邻两个拼装管体中，高度较高处拼装管体的外侧壁上竖向开有顶撑槽，高度较低处拼装管体上开有插接槽，高度较高处拼装管体的底部通过插接槽与高度较低处的拼装管体插接配合，高度较低处的拼装管体上螺纹连接有抵紧于顶撑槽内的紧固螺栓；选取合适数量的拼装管体，通过相邻两个拼装管体的插接并配合紧固螺栓，将多个拼装管体组装成为整根沉管；沉管顶部安装振动锤锤击沉管使周围土体挤密，当沉管打入设计深度后，从沉管顶部的漏斗处灌入混凝土。本申请具有灵活调节沉管整体长度，进而适用于浇筑不同深度灌注桩的优点。
