Description
The addition of force measuring component in the YXI series permanent ground anchor differentiates it from the YX series. This allows the dispersion of internal stress in the anchor body meanwhile monitoring the internal force in each steel strand of the anchor. Furthermore, the bearing capacity of each anchor unit can be analyzed based on the measurements. The strain gauge is protected under the waterproofing state and this allows the intelligent anchor to possess great accuracy in force measurement and durable. At present, this kind of intelligent anchor can be manufactured at one time in the factory and the overall quality of the anchor is guaranteed.

Frequently asked questions

Q1: What is jet grouting?
A: The jet grouting process mainly adopts an improvised high-pressure rotary spray method to form an anchoring section of the rotary spray underreamed anchor on the bottom plate of the anchor.

① Unbonded tendon with wire;
② Free segments;
③ Hot melt anchors;
④ Bearing plate;
⑤ Anchoring section;
⑥ Anchor;
⑦ Base plate

Q2: 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.

Q3: 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.

Q4: How many cable structures can this product built up at most?
A: Using only this model, 6 cables can be built at most where the largest internal diameter of the anchor rod body is 205mm.

Q5: Is this product environmental friendly?
A: The materials used by the anchor consists of three types which is steel, wrapping layer of the steel strands covered in strong PE and PE. All these materials will not cause negative impact to the environment.

Q6: How well does this product resists to corrosion?
A: It is handled by SSPC—SP5 level anti-corrosive treatment.

Q7: What is the size of the casing used by this product?
A: This product adopts jet grouting process in construction instead of casing. For ground layer that is hard and direct advancement is not allowed, three-wings drilling bit is used to drill holes beforehand followed by jet grouting.
