Generally, the micropile shaft is both driven or drilled into posture. Some sort of bearing component has to be established if the required pile potential can't be attained in end bearing and side friction along the pipe. This may entail drilling a rock socket, filling it with grout, and putting in an entire duration, significant-strength threaded bar In case the idea is roofed in rock.
A substantial-energy metal casing is often drilled down to the design depth in the course of the installation procedure. A reinforcing bar is put into the casing, and large-toughness cement grout is poured into it.
Cementitious grout in addition to strain is fed in to the minipile casing and rock socket. Right after Tremie grouting, accomplish a force grouting by means of preinstalled grouting tubes.

All through the construction in the micropile, the drilling penetration rate is often monitored as a sign from the stratum currently being drilled. Grout should be sampled for subsequent compressive strength screening.
Drill rod is withdrawn and the metal casing remains. On achieving the saturation degree the drilling little bit is รับตอกเสาเข็มไมโครไพล์ นนทบุรี withdrawn with casing still left throughout the bore-gap.
Principal grout is completed under pressure and soon after coagulation, secondary grout is concluded by way of put in sleeve ports.
Grouting Process: Engineers บริการตอกเสาเข็ม ราคา use pressure grouting to boost bond strength in between the pile and surrounding soil or rock.
