Construction technology for reducing concrete diffusion condition of karst cave part through rotary excavating of cast-in-place pile
The invention relates to the technical field of civil engineering pile construction, in particular to a construction technology for reducing the concrete diffusion condition of a karst cave part through a rotary excavating cast-in-place pile, and the construction technology comprises the following steps: S1, detecting karst cave data at a construction part; s2, rotary drilling forming of a pile hole is carried out; s3, drainage is conducted on the pile hole; s4, a reinforcement cage is manufactured, and the reinforcement cage is sleeved with an isolation net capable of isolating concrete from diffusing outwards according to the karst cave data recorded in the step S1 and the step S2; s5, a reinforcement cage is lowered, and the separation net blocks the karst cave; and S6, pouring forming of a cast-in-place pile is conducted on the pile hole. In the pouring forming process of the cast-in-place pile, the separation net can block the karst cave position, the concrete diffusion situation of the karst cave position can be reduced, the concrete consumption is reduced, and then the engineering cost can be further reduced.
本申请涉及土木工程桩施工技术领域，尤其是涉及一种旋挖灌注桩用于减少溶洞部位混凝土扩散情况的施工工艺，包括如下步骤：S1、探测施工处溶洞数据；S2、进行桩孔的旋挖钻孔成型；S3、对桩孔进行排水；S4、S4、制作钢筋笼，参照步骤S1、S2中所记录的溶洞数据，在钢筋笼套设能够隔离混凝土向外扩散的隔离网；S5、下放钢筋笼，使隔离网封堵于溶洞；S6、对桩孔进行灌注桩的灌注成型。本申请在灌注桩浇筑成型过程中，隔离网能够对溶洞位置处进行封堵，能够减少溶洞部位混凝土扩散情况，以节省混凝土用量，进而能够进一步降低工程成本。
