The technological process of installing self drilling bolt
The anchor bolt (including soil nailing) and prestressed anchor for on-site processing, its production method and process directly affect the quality.
The technological process is as follows: drilling and making self drilling anchor bolt, clear hole, install the self drilling anchor bolt, grouting and compensating grouting are applied, a prestress is fixed and an end is processed. The prestressed anchor cable by multi beam steel wire woven, prestressing requires specialized equipment, the construction quality is different, and
products for factory production, reduce the production and two processes of installation of anchor bolt, prestressed simply tighten the bolts can improve the bearing capacity of 25%,reliable quality, improve work efficiency.
