Generally speaking, micropiles are a kind of concrete pile adopting the construction technology of drilling, strong reinforcement and pressure grouting, less than 400mm pile diameter and over 30 slenderness. Its construction equipment is rather small, suitable for narrow construction sites; low noise and consumable items while high capacity, suitable for urban construction.
Micropiles have closer relationship with people and its design, construction and monitoring technology have become a technical problem gradually. It can not only make foundation construction safe and stable, but also prevent deformation, soil body moving, which keep the normal operation of surrounding buildings, roads and underground pipelines. Nowadays, supporting structures are perfecting gradually. Sinorock® Self Drilling Anchor Bar, as a new way of supporting deep foundation, is widely used increasingly.
1. Offer underpinning brackets for compression foundation remediation and floors remediation applications.
