Construction method of cement reinforced soil pile
The invention discloses a construction method of a cement reinforced soil pile. The construction method comprises the following steps that S1, a mixture is put into a slurry spraying pile machine, and holes are punched with the diameter of 400-600mm and the depth of 7-12m at the interval of 2-3m; S2, the punched holes are tamped in rows, the thickness of the mixture filled in each hole every time is 60-70 cm, tamping is carried out for 15-30 times, tamping is carried out in sequence till the distance between the hole and the pile top is 30-80 cm, and the holes are tamped and sealed to the pile top with a premixed material; and S3, after pile forming of the first-order holes is completed, pile forming operation of the second-order holes is started, accumulated water and hole shrinkage conditions in the second-order holes are checked firstly, accumulated water in the holes is discharged, if hole shrinkage is carried out, hole expanding treatment is carried out, hole expanding is carried out till the diameter is 140-160 mm, then tamping pile forming operation is carried out, the pile forming operation is the same as that of the first-order holes, and the cement reinforced soil pile is manufactured. According to the construction method of the cement reinforced soil pile, the foundation bearing capacity can be effectively improved, the foundation settlement amount is reduced, and engineering benefits are quite remarkable.
本申请公开了一种水泥加固土桩的施工方法，S1，将混合料放入浆喷桩机，采用2～3m为间距打孔，孔直径为400～600mm，孔深7‑12m；S2，对所打孔采用隔排夯实作业，每孔每次填混合料厚度为60～70cm，夯击15～30次，依次夯击至距离桩顶30～80cm，用预拌料夯实封孔至桩顶；S3，第一序孔成桩完毕后，开始第二序孔的成桩作业，先检查第二序孔内的积水和缩径状况，将孔内积水排出，如果缩径，进行扩孔处理，扩孔至直径为140～160mm，然后进行夯实成桩作业，成桩作业同第一序孔，制成水泥加固土桩。该施工方法能够有效提高地基承载力，减小地基沉降量，工程效益十分显著。
