1. The insurance function of dual lines:

The technical performance difference between using two single lines together and the "double line structure design" is that when two single lines are used at the same time, they are prone to entanglement and breakage. When two single lines are auxiliary, they cannot achieve equal length and parallel use, and the distribution of tensile force points is uneven, which can lead to uneven order of fracture of the two single lines. The tensile strength can only reflect the strength of one line. The "double line structure design" has already glued two branch lines together. Due to structural changes, its technical performance has formed *, which can be used in equal lengths and parallel. The tensile force points are evenly distributed, forming a unified tensile strength technical index, breaking through the influence of low tensile strength of existing tracer wire products.

2. Convenient for simple on-site inspection and judgment of the quality of tracer wire laying.

Connection method of LYA-SZ3 tracer wire for buried PE pipes

The LYA-SZ3 tracer wire has protective joints for connecting lines, which are waterproof

A corrosion-resistant sealed chamber, where the exposed tracer wire head is placed inside the sealed chamber to protect the exposed tracer wire head from corrosion; The joint is made of PE material and has the ability of corrosion resistance and aging resistance.

The connection method of thin film tracing wire and wire tracing wire: Twist the two wire ends together, and generally use heat shrink tubing or waterproof tape as the joint treatment. The anti-corrosion and waterproof effects are determined by the material and construction effect of the heat shrink tubing.

Detection of buried PE pipe LYA-SZ3 tracer wire

LYA-SZ3 tracer wire: Conventional laying, effective detection distance above 1000 meters when buried depth ≤ 1.8 meters; When laid without excavation and buried at a depth of ≤ 4 meters, the effective detection distance is 500 meters; When laid without excavation and buried at a depth of ≤ 7 meters, the effective detection distance is 300 meters.

Thin film tracer wire: Conventional laying, effective detection distance within 150 meters when buried depth ≤ 1.8 meters; Cannot be used for non excavation laying.

The wire tracer wire is similar to LYA-SZ3, but non excavation laying requires wires with a cross-sectional area of more than 6 square meters, which is not cost-effective.

Application of Buried PE Pipe LYA-SZ3 Tracer wire in Non Excavation Crossing

Bundle the tracer wire onto the steel wire ring of the equipment support head and tighten it again with iron wire or snap ring.

Fix the tracer wire and PE pipe with tape every 5-8 meters.

After the pipe jacking is completed, connect the two wires at one end of the tracer wire together, and use a multimeter to measure the other end of the tracer wire to see if there is a pathway.
