Jacking Pipes Cast-in Anti-Slide Steel Collar

G-Cast concrete jacking pipes with cast-in ANTI-SLIDE steel collar are innovatively designed in view to enhance the overall performance of the jacking pipes with a significantly improved joint design.

Normal cast-in steel collars for concrete jacking pipes are made of flat steel plate with welded anchorage bars for means of anchorage into concrete. The specially designed G-Cast ANTI-SLIDE steel collars are however made of steel plates that are not just flat but come with two all-round preformed groove lines. These additional groove lines give the steel collar a better rigidity, an additional means of positive bonding, anchorage and locking into concrete and also it helps to prevent collar from sliding off the concrete during jacking operation.
