What are the steps to install the double expansion anchor

During the installation of Double Expansion Anchor, adequate preparation is the key to ensure successful installation. The following are the detailed steps for preparatory work before installation, determination of drilling parameters, hole drilling, hole cleaning and anti-rust treatment, and insertion and fixing of anchor bolts.

Preparatory work before installation
Design and scheme confirmation
According to the specific structure and force requirements of the project, a detailed design scheme is confirmed. The professional engineers of Yuyao Nanshan Development Co., Ltd. will provide technical support to ensure that the installation position, quantity, specifications and other parameters of the anchor bolts meet the design requirements. The accuracy of this link directly affects the safety and effectiveness of subsequent construction.
Material preparation and inspection
Before installation, the required Double Expansion Anchor materials, including the anchor bolt body, drill bit and corresponding supporting tools, must be prepared. All materials are strictly inspected to ensure that their quality meets the standards and to avoid defects such as rust and cracks. The anchor bolt products provided by Yuyao Nanshan Development Co., Ltd. have undergone strict quality inspections to ensure their reliability during use.
Construction site survey
Conduct a comprehensive survey of the construction site to understand the geological conditions, existing facility structures and other related factors in order to develop a reasonable construction plan. Special attention should be paid to factors such as temperature and humidity in the construction environment, which will affect the installation effect of the anchor bolts.

Determine drilling parameters and hole excavation
Determine the diameter and depth of the hole
According to the specifications and models of the Double Expansion Anchor to be installed, clarify the diameter and depth of the hole. The diameter of the hole should be slightly larger than the diameter of the anchor bolt to ensure that the anchor bolt can be inserted smoothly. The drilling depth should meet the design requirements to ensure that the anchoring depth of the anchor bolt reaches the expected effect.
Hole excavation
Use professional equipment to excavate the hole to ensure that the hole position is accurate and the hole wall is smooth. The professional drilling tools and construction guidance provided by Yuyao Nanshan Development Co., Ltd. will ensure the safety and efficiency of the hole excavation process.

Clean the dust in the hole and rust prevention treatment
Clean the dust in the hole
After the hole excavation is completed, the hole must be thoroughly cleaned to remove dust, debris and other debris in the hole. This process is essential to improve the stability of the anchor installation.
Anti-rust treatment
Before installing the Double Expansion Anchor, the anchor needs to be treated with anti-rust treatment. Yuyao Nanshan Development Co., Ltd. provides a variety of anti-rust treatment methods, including electroplating and painting, to ensure that the anchor is not affected by corrosion during use, thereby extending its service life.

Anchor insertion and fixation
Anchor insertion
Insert the treated Double Expansion Anchor into the hole to ensure that the expansion part of the anchor can be fully expanded.
Apply external force
Use a special installation tool to apply external force to the anchor so that the expansion part expands in the hole and fits tightly with the hole wall. The installation tools provided by Yuyao Nanshan Development Co., Ltd. are efficient and stable, which can ensure the fixing effect of the anchor and thus improve the safety of the overall structure.
