Double-pile-casing drilling construction process of rotary drilling drill for sand-rich stratum in riverside area
A rotary drilling and double-pile-casing drilling construction process for a sand-rich stratum in a riverside area comprises the steps that S1, auxiliary supporting bases are poured, specifically, at least three auxiliary supporting bases are evenly arranged on the outer side of a pre-drilling position, all the auxiliary supporting bases are kept at the same horizontal height, stand columns are vertically fixed to the auxiliary supporting bases, and fixed pulleys are arranged at the tops of the stand columns; s2, arranging a winch on each auxiliary supporting base; s3, an outer pile casing and an inner pile casing are machined; s4, the outer pile casing is installed, in the construction process, the ends of traction cables on the winches are fixed to lifting lugs of the outer pile casing, in the outer pile casing installation process, the traction cables on all the winches are in a tensioned state, and the lengths from the lifting lugs of the outer pile casing to the winches are kept consistent; s5, the inner pile casing is installed, the inner pile casing is arranged in a vibration mode after the outer pile casing is installed and rechecked, and rechecking is conducted once every 3 m; and S6, concrete pouring is conducted, after pouring is completed and before initial setting of concrete, the inner pile casing is pulled out firstly, and then the outer pile casing is pulled out.
一种滨河地区富砂地层旋挖钻双护筒钻进施工工艺，包括S1、辅助支撑基浇筑，在预挖钻处的外侧均匀设置至少三处辅助支撑基，所有辅助支撑基保持同一水平高度，且在辅助支撑基上垂直固定立柱，在立柱的顶部设置定滑轮；S2、在每个辅助支撑基上设置卷扬机；S3、加工外护筒以及内护筒；S4、安装外护筒，在施工过程中将卷扬机上的牵引索的端部固定于外护筒的吊耳上，在安装外护筒过程中每个卷扬机上的牵引索处于张紧状态且由外护筒的吊耳至卷扬机之间的长度保持一致；S5、安装内护筒，外护筒安装完成且复核后振设内护筒，每3m进行复核一次；S6、混凝土浇筑，浇筑完成后在混凝土初凝前，先拔除内护筒，再拔出外护筒。
