Self-Drilling Anchor Support in Construction

by Una S. Website Marketing Specialist

Self-drilling anchor support can take full advantage of soil body’s self-bearing capacity. Compared to shotcrete support, it has characters of safety, high efficiency and convenience. It can be operated at small spaces, so under allowable conditions, the adopting self-drilling anchor can enhance efficiency largely.

1. Applicability

Generally speaking, self-drilling anchor is suitable for foundation pit support or slope reinforcement with artificial soil, clayey soil and weak cement sandy soil above underground water or after artificial precipitation.

2.  Engineering investigation

Engineering investigation is an essential work for ensuring projects’ safety and reliability. As for self-drilling anchor projects, two points should be noticed especially: underground pipelines and underground water. Distribution of underground pipelines and underground water should be listed in the investigation report in order to do design work in advance.

3. Design and monitor problems

Based on soil condition, soil deformation and stressed condition of self-drilling anchor, the distance and length of self-drilling anchor should be adjusted.

Correct and reasonable design is the precondition for ensuring construction quality, which directly influences engineering safety, duration and economic investment.

Monitoring work mainly includes horizontal deformation, settlement, stress force of self-drilling anchor and soil pressure. They can be chosen according to practical situations.
