RZI series temporary removable strand anchor combined the real-time internal force measurement and recoverable function. It is mainly used in large scale foundation pit and slope project which allow anchor to be recovered and real-time measuring to ensure safety. The strain gauge is located at the tip of the anchoring section which wrapped in filler. As compared to the conventional anchor that equipped with strain gauge, the strain gauge is protected under the waterproofing state and this allows the intelligent anchor to be more durable and possess great accuracy in force measurement. The recoverable property solves the problem of leftover tendon residue in the soil effectively. Traditionally, tendon remains in the soil layer which results in material waste, soil pollution and creating more obstacles in the soil which increases the difficulty in future development of the surrounding underground space. Higher cost has to be spent to remove these obstacles as well. However, with the use of hot melt removable technology, all the tendons can be removed or recovered after the bracing project completed.

Features
  • Allow real-time monitoring of the anchor bearing capacity. It can monitor up to the internal force of each steel strand in the anchor and thus having greater accuracy.
  • Removable anchor suitable for use in temporary construction project
  • Allow multiple combinations and thus forming stress-dispersive structure
  • Handled by SSPC-SP5 anti-corrosive treatment
Frequently asked questions

Q1: Is the intelligent force measurement of this product measuring each anchor?
A: The accuracy of the intelligent anchor measurement measures up to each steel strand.

Q2: How is the measured data observed?
A: Real-time observation can be made via mobile gadgets, computer and so on as the data is transmitted to the device via wireless transmission after on-site measuring.

Q3: How is the safety level of this product?
A: The static load coefficient of the hot melt removable anchor reached 96% which is nearly the same as the strength of steel strand. Besides, it satisfies the large fatigue test up to 2 million times and therefore it is applicable in permanent structure.

Q4: How is the recovering speed?
A: With the use of fully automatic recovering equipment, taking 6 anchors with length 25 meters as an example, a group of 2 people in assembly line can complete the recovery of 90 anchors.

Q5: How much is the recovery rate of the anchor?
A: The rate is higher than 95% normally. Approaches can be made to realize 100% recovering rate.

Q6: How many cable structures can this product built up at most?
A: Using only this model, 5 cables can be built at most where the largest internal diameter of the anchor rod body is 100mm. If you wish to increase the quantity of the cable, please refer to the combination of grouting anchor.
