Complex geology cast-in-situ bored pile guide drilling construction method
The invention relates to a complex geology cast-in-situ bored pile guide drilling construction method. The method comprises the following steps that S1, a steel casing is arranged; S2, a three-sectiondie with a reserved groove is installed on the upper portion of the outer side of the steel casing; S3, small holes allowing grouting pipes to be inserted are reserved in a prefabricated plate and afirst steel plate correspondingly, and the grouting pipes are inserted into a reinforced soil area of the side wall of the bottom of the steel casing from the earth surface through the small holes reserved in the prefabricated plate and the first steel plate; S4, I-shaped steel and split bolts are adopted for manufacturing longitudinal stocks; S5, the longitudinal stocks and transverse inner supports are arranged around a drilled hole; S6, a drill bit is manufactured, and a drill cylinder is arranged around the outer side of the drill bit; S7, a drill bit stabilizer is installed at the upper portion of the drill cylinder, and a drill rod stabilizer is installed at the upper portion of the drill bit stabilizer; S8, an adjusting ring is mounted on a drill rod; and S9, the drill bit is connected with the drill rod, and a drilling machine is used for drilling in the steel casing. The method has the beneficial effects that the steel casing is fixed through limiting rods I longer than the steel casing, so that the steel casing can be better prevented from deflecting.
本发明涉及复杂地质钻孔灌注桩导向钻孔施工方法，包括步骤：S1、打设钢护筒；S2、在钢护筒外侧上部安装预留有凹槽的三瓣模；S3、预制板及钢板一均留有插入注浆管的小孔，注浆管从地表经过预制板及钢板一所预留小孔内插至钢护筒底部侧壁的加固土区域；S4、采用工字钢和对拉螺栓制作纵向砧木；S5、纵向砧木和横向内撑布置在钻孔周围；S6、制作钻头，在钻头外侧一周设置钻筒；S7、钻筒上方安装钻头稳定器，钻头稳定器上方安装钻杆稳定器；S8、在钻杆上安装调节环；S9、将钻头连接钻杆，利用钻机在钢护筒内钻进。本发明的有益效果是：本发明通过比钢护筒长的限位杆一固定钢护筒，可更好的防止钢护筒偏斜。
