Pile casing device for cast-in-place pile construction and rotary drilling rig
The invention firstly provides a pile casing device for cast-in-place pile construction. The pile casing device comprises a driving sleeve, one or more pile casings, a boot and a connecting pin, the connecting pin is used for connecting the driving sleeve, the pile casings and the boot in the vertical direction, the connecting pin comprises a threaded section located on the radial outer side of the pile casing device and a circular truncated cone section located on the radial inner side of the pile casing device, and a fastening hole is formed in the radial center of the threaded section. And the fastening hole is used for fixedly arranging the connecting pin in a through hole of a driving sleeve, a pile casing or a boot. The invention further provides a rotary drilling rig comprising the pile casing device for cast-in-place pile construction. The construction method and the pile casing device which are economical, practical, efficient and energy-saving are provided for construction of a construction site, the construction cost is reduced, more benefits are created for users, and meanwhile construction is safer and safer.
本发明首先提供一种用于灌注桩施工的护筒装置。所述护筒装置包括驱动套、一节或多节护筒、筒靴以及连接销，所述连接销用于在上下方向连接驱动套、护筒和筒靴，所述连接销包括处于护筒装置径向外侧的螺纹段和径向内侧的圆台段，且在所述螺纹段的径向中心位置设置有紧固孔，所述紧固孔用于将所述连接销固定设置在驱动套、护筒或筒靴的通孔中。本发明还提供一种包含该用于灌注桩施工的护筒装置的旋挖钻机。本发明给工地施工提供了一种经济实用、高效节能的施工方法和护筒装置，在降低施工成本，为用户创造更多利益的同时，让施工更安全、安心。
