Drill rod is withdrawn plus the metal casing continues to be. On achieving the saturation stage the drilling little bit is withdrawn with casing left throughout the bore-gap. A reinforcement load bar is decreased in the casing.
Grouting: The casing is full of large-power grout to protected it set up, making certain stability and reinforcing the pile’s energy.
They can be place in on The รับตอกเสาเข็มไมโครไพล์ ราคาถูก purpose of present partitions with limited headroom and engorged website ailments.
Reinforcing steel, ordinarily an all-thread bar is inserted in the casing. Substantial-power cement grout is then รับตอกเข็มไมโครไพล์ pumped in to the casing. The casing may extend to the total depth or close higher than the bond zone, While using the reinforcing bar extending to the entire depth.
The grouting for that team A micropiles is ready less than gravity. In group B, grout is injected under pressure into the opening, but the strain is constrained to prevent hydrofracturing of your close by soil. Team C micropiles are set up in two methods: initial, a Key grout is force-applied to hydrofracture the surrounding floor, and then, just before the main grout sets, a secondary grout is injected via a manchette tube.
