Self Drilling Anchor Bar
Self Drilling Anchor Bar is a new type of anchoring material. It can drill holes by itself, which greatly reduces the difficulty and labor intensity of installation. Since the self-drilling anchor uses a hydraulic arm to drill deep into the soil layer and then tensions the anchor, it generates self-stress, which greatly improves the bearing capacity of the anchor. The anchoring area of the self-drilling anchor is larger than that of ordinary anchors, and the bearing capacity is higher.
Description
Self Drilling Anchor Bar can be divided into Self Drilling Anchors Bolts T Thread and Self Drilling Anchor Hollow Bar R Thread.
Features of Self Drilling Anchor Bar
Self Drilling Anchor Bar is a new type of anchoring material, and its main features are as follows:
1. Strong self-drilling: Self-Drilling Anchor Bolts can drill holes by itself, which greatly reduces the difficulty and labor intensity of installation.
2. Self prestressing: Since Self Drilling Anchor Bar uses a hydraulic arm to drill into the depth of the soil layer, and then tensions the anchor rod, it generates self-stress, which greatly improves the bearing capacity of the anchor rod.
3. High bearing capacity: The anchoring area of Self Drilling Anchor Bar is larger than that of ordinary anchor rods, and the bearing capacity is higher.
4. Easy to use: No excavation equipment is required during the installation process, which is suitable for occasions with small construction space.
Application fields of Self Drilling Anchor Bar
1. At present, Self Drilling Anchor Bar has been widely used in earthwork engineering, tunnel engineering, basement and mining engineering.
2. It can be used to reinforce soft foundations and resist the sliding and settlement of soil;
3. it can also be used to enhance the stability of tunnels, basements and mines. In addition, in water conservancy and environmental protection projects, Self Drilling Anchor Bar can also be used to reinforce river channels and fixed equipment in petrochemical plants.
In short, Self Drilling Anchor Bar has the characteristics of self-drilling, self-prestressing, high load-bearing, and easy to use. It is an efficient, easy-to-construct, economical and practical anchoring material. It has broad application prospects in engineering construction.
