Interlocking Steel Pipes Curtain

Contiguous or Secant Piles are commonly used to construct continuous CURTAIN WALLS, and DTH Systems are very suitable for this applications, in difficult ground Conditions a/o when Rock socketing is required. Normally Cased drilling is required, in order to grant proper verticality and alignment of the curtain.
Maxa DTH Casing Systems are frequently utilized for this purpose.
MOREOVER MAXA HAS DEVELOPED A SPECIAL APPLICATION, CALLED “INTERLOCKING STEEL PIPES CURTAIN”, WHICH IT HAS PIONEERED YEARS AGO and then successfully implemented globally.
THIS TECHNOLOGY CONSISTS OF DRIVING STEEL PIPES OF UP TO 1.200MM DIAMETER BY MEANS OF DTH SPECIAL CASING SYSTEM, GRANTING A PERFECT INTERCONNECTION BETWEEN THE STEEL PIPES BY MEANS OF VERTICAL JOINTS WELDED ALONG THE SAME.
SIMULTANEOUSLY TO THE DRILLING (BY MEANS OF SPECIAL OVERSIZED DTH BIT SET, WHICH IS ALLOWING FOR THE REQUIRED EXTRA DRILLING SPACE REQUIRED FOR INCORPORATING THE JOINTS), THE M/F JOINTS ARE SLIDED INTO EACH OTHER AND THE CURTAIN IS COMPLETED.
IN ADDITION TO VERY HIGH PRODUCTIVE RATES, this solution allows to drill any required length of Rock Socketing, which is essential for an efficient static behavior of the Curtain.
THIS METHOD IS ALSO OVERCOMING ALL THE POSSIBLE PROBLEMS DUE TO LACK OF PRECISION IN CASE OF TRADITIONAL CONTIGUOUS OR SECANT PILES CURTAINS (gaps between the piles, causing leakage of material and inaccurate curtain alignement, requiring extra mending works, etc.).
Maxa is able to provide not only the MOST SUITABLE DRILLING SETS FOR THIS KIND OF APPLICATIONS, but also on request THE VERTICAL M/F JOINTS OF ITS OWN DESIGN and STEEL PIPES of the required diameter and Steel Grade. If you want a durable and dependable drilling equipment with powerful drilling penetration rate in competitive price, MAXA mark series is definitely your choice.
