Reinforcing steel, generally an all-thread bar is inserted into your casing. Large-strength cement grout is then pumped to the casing. The casing may perhaps lengthen to the entire depth or finish previously mentioned the bond zone, with the reinforcing bar extending to the total depth.
Alternatively some other acceptable process such as filling the bore with coarse aggregate upto specified height of about 1m and filling it subsequently with cement grout can also be proposed.
Grouting Process: Engineers use force grouting to รับตอกเสาเข็มไมโครไพล์ นนทบุรี further improve bond energy concerning the pile and surrounding soil or rock.
The hollow threaded rebar technique is also known as a self-drilling hollow bar technique. In This method, the hollow bar can function for a sacrificial drill bit. It will get transformed to the central reinforcement. It may also be accustomed to flush out the particles. This technique can do away with pre-drilling and Recurrent removal of pipes and drills.
