Anchor support is a fundamental reinforcement method utilized in various surface and underground construction projects. This technique enhances the stability of structures like slopes, deep foundation pits, tunnels, and stops by integrating the support system into the surrounding rock mass.
The installation can achieve drilling and grouting simultaneously. The unique design of the anchor's head, body, and optional tail support plate, or adhesive bonding, synergizes with the stable rock mass to provide suspension, composite beam effects, and reinforcement.
If you're wondering how to install self-drilling anchor or seeking guidance on self-drilling anchor installation, these versatile fasteners offer a convenient solution for your construction needs.
In this step-by-step guide, we will explore the benefits of using self-drilling anchors and provide valuable tips and tricks to ensure successful self-drilling anchor installation.

A Step-by-Step Guide on How to Use Self Drilling Anchors for Easy and Secure Installation
Necessary Tools for Self-Drilling Anchor Installation
Before you start installing self-drilling anchors, it is important to gather all the necessary tools and equipment to ensure a smooth installation process. Here are the tools you will need: Power Drill: A power drill is essential for drilling holes in the material. Make sure to use a drill with sufficient power and the appropriate drill bit size for the self-drilling anchor you are using. Hammer: A hammer is needed to gently tap the self-drilling anchor into the pre-drilled hole, ensuring a tight fit. Setting Tool: Some types of self-drilling anchors, such as drop-in anchors, require a setting tool to expand the anchor and secure it in place. Make sure to use the appropriate setting tool for the anchor you are using. Safety Equipment: It is important to wear safety goggles and gloves during the installation process to protect yourself from any potential hazards.Guide on How to Install Self-Drilling Anchor
The following instructions will help you master the art of self-drilling anchor installation: Self-drilling hollow grouting anchor bar roll forming technology to form full-length threads on its surface, and cooperates with various components to achieve the integration of anchor drilling, grouting, anchoring and other functions. 1. There is an alloy drill bit with strong penetrating power in front of the anchor bar, which can easily penetrate all kinds of rocks under the action of rock drilling tools. 2. The anchor bar with continuous corrugated threads (international R&T standard), could be used as a drill rod to complete drilling with a drill bit. 3. The anchor body as a drill rod does not need to be pulled out, and its hollow space can be used as a grouting channel from the inside to the outside. 4. The high-strength connecting coupling enables the self-drilling anchor bar to have the characteristics of lengthened drilling, which can be applied to a narrow construction space and realize the ideal design of extra-long anchor rod to strengthen the surrounding rock. 5. The self-drilling anchor bar has three-in-one function, can form anchor holes and ensure anchoring and grouting effects without casing wall protection, pre-grouting and other special techniques when constructing under various surrounding rock conditions. By following these detailed steps and guidelines, construction projects can leverage the full benefits of anchor support. This method offers cost-effectiveness, operational ease, flexibility, and minimal space requirements, making it an ideal choice for reinforcing structures in challenging environments.Construction technology
1) Drilling: Use anchor trolley or hand-held drill rig to drill the anchor bar with drill bit, and drill the designed depth. (If the anchor bar needs to be lengthened, it can be connected with a coupling.) 2) Remove the drill rig, install grout stopper on the anchor bar, 25cm away from the hole opening. In special circumstances, when the grouting pressure is high or the surrounding rock is too broken, could be resin to seal the holes. 3) Connect the exposed end of the anchor bar to the grouting machine through a quick grouting joint. 4) Start grouting and stop when the grouting is full and the pressure reaches the design value. The grouting pressure is determined based on the design parameters and grouting machine performance. Water-cement ratio reference value: (0.35~0.45):1. 5) Install backing plates, nuts, etc. according to design.Common Mistakes to Avoid During Self-Drilling Anchor Installation
While using self-drilling anchors can simplify the installation process, there are some common mistakes that you should avoid to ensure a successful installation: Incorrect anchor size: Using the wrong size of self-drilling anchor can compromise the strength and stability of the installation. Always refer to the manufacturer's guidelines and select the appropriate anchor size for your specific application. Insufficient drilling depth: It is important to drill the holes to the recommended depth specified by the manufacturer. Insufficient drilling depth can result in a weak and insecure connection between the anchor and the material being fastened. Over-tightening the anchors: While it is important to tighten the self drilling anchors securely, over-tightening can lead to damage or failure of the anchor. Follow the manufacturer's guidelines for the specific anchor type to ensure proper tightening.ONTON: Your Trusted Source for High-Quality Self-Drilling Anchor Bolts
