介绍了玻璃钢锚杆材质的性能和锚杆的结构特点试验情况。
he bolt body can be wood,steel,bamboo and steel cable.But it can also be a resin fibre bolt body.The resin body will have a lower special gravity and higher tensile strength than a steel body.The resin body is acid resistant、corrosion resistant and rust free and can be used instead of a steel bar body.After test,an anchorage strength of the draw pressed resin fibre bolt body with a diameter of 16mm can be over 40～50 kN which could meet with the requirement of bolt support in mine rock roadway and seam roadway.The resin body is made of glass fibre and unsaturated polyester resin.The unsaturated polyester resin can be bond with glass fibre under a certain condition and the glass fibre has a reinforce function.Due to a mechanical production of the resin bolt body,the length of the body can be variable.The resin body has a high mechanical strength and a high glass fibre content over 70%.The head of the resin body can be drilled and fitted with iron wire.The end of the resin bolt body can be used with a wedge block or screw nut.Both will have a anchorage strength over 50kN.
