Product Description

Application

The casing are designed to perform cased holes. Especially for the construction of bored piles by rotary drilling rigs the casing joints due to the machning accuracy guarantee a fast placement and bolting of the casing as welll as best force transmisssion


Specification

Double-wallled casing can be used universally,as they are designed especiallly for transmitting high rotational annd vertical forces as created by the ratary drives and oscilllators. The use of double-walled casing ensures a flush drill string. Single-walled casings can be used for appllications where weight reduction is importannt.


Features of Casing Rotary Drilling Method:


1-High efficiency construction: Oscillator drive the casing (Protect wall during drilling and cast in place ). Rotary rig takes out soil from casing (High-efficiency drilling).
2-Safty construction: Double isolated by casing during drilling and cast-in-place, no disturbance to surrounding building foundation (near subway and high-rise building construction).
3-Environmentally friendly construction: No mud discharge, dry drilling, and the drilled rock and soil can be recycled.
4-Broad-spectrum construction: suitable for all kinds of complicated formations, gravel layers, strongly weathered rock formations; casing drilling ahead in the soft layer, drilling tools ahead in the hard layer.
5-Casing verticality: Rotary rig controls verticality in a shallow layer, and the oscillator controls verticality in the deep layer.
6-Power pack of oscillator: Independent power pack(Oscillator and Rotary rig operate independently, do not interfere with each other), or use the power from the rotary rig).
