GB/T 18365-2018Hot-extruded PE protection paralleled high strength wire cable for cable-stayed bridge (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 18365-2001 "Technical conditions for hot-stretched polyethylene high-strength steel cables for cable-stayed bridges". With GB/T 18365-

Compared with.2001, the main technical changes are as follows.

--- Added terms and definitions for built-in vibration dampers (see 3.1.6);

--- Increased the classification of cables (see 4.1);

--- Revised the model representation of cables and anchors (see 4.4,.2001 version 4.2);

--- Increased zinc-aluminum alloy coating steel wire material (see 5.2.1);

--- Increased high-strength steel wire strength level (see 5.2.1.3);

--- Removed no relaxation of steel wire and Class I relaxation requirements (see version 4.5.1.7 of the.2001 edition);

--- Modify the main performance indicators of high-density polyethylene sheath material (see 5.2.2, version 4.5.2 of the.2001 edition);

--- Increased anchorage filler strength definition (see 5.2.4.2);

--- Increased the definition and requirements of the cable attachments (see 5.2.6);

--- Modify the process performance requirements (see 5.4, Chapter 5 of the.2001 edition);

--- Increased material testing methods (see 6.2);

--- Increased cable tightness test (see 6.3.4);

--- Removed inspection of raw materials (see 6.1 in.2001 edition);

--- Increased the specific requirements of the inspection rules (see Chapter 7, Chapter 6 of the.2001 edition);

--- Removed other requirements (see Chapter 8 of the.2001 edition);
