Type RX Temporary Strand Anchor
Type RX temporary strand anchor is a removable anchor which forms an underreamed anchoring section at the bottom plate of the anchor using the jet grouting process and distributes the bearing plate over the anchoring section reasonably. Hence, the dispersion of the internal stress can be achieved. The anchor adopts the hot melt removable technology and thus all the tendon bodies can be removed after the bracing work completed. Clearly, this allows material saving and able to protect the soil at the same time providing a green construction environment for the adjacent underground space, effectively solving the problem of leftover tendon residue in the soil.

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 segment;
③ Hot melt anchor;
④ Bearing plate;
⑤ Anchoring section;
⑥ Anchor;
⑦ Base plate
Q2: 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.
Q3: 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.
