Common Sense Maintenance Of right-Handed Equal-Strength Threaded Anchors

Common sense maintenance of right-handed equal-strength threaded anchors

To introduce you to the maintenance of right-handed equal-strength threaded anchors: Mining anchors have irreplaceable advantages compared with traditional metal anchors. In the performance of the rod body is easy to cut, the coal mining machine cutter head to play a protective role; explosion-proof and anti-static, cutting does not produce sparks, the roadway construction is beneficial, especially suitable for high gas concentration areas; high strength and corrosion resistance, lightweight and easy to operate, the weight of the same specifications for the steel anchor rod 1/4. can be in the tunnels and coal mines, such as the use of small space, so that the construction of the construction is easier to reduce the labor intensity of the workers, the price is lower than the metal anchors. The price is lower than that of metal anchors, which can reduce the cost of anchor support by 10.

Mining anchor is a kind of anchor used for underground support of coal mine, this kind of anchor full-length equal strength, the length can be intercepted according to the demand, good anchoring performance, simple and reliable, high strength, construction and other advantages make it mainly used for underground support, can also be used for other projects support.

Attention matters:

(1)Pick the position where the rock and coal at the pallet is flat and no broken phenomenon;

(2) The pad should try to pick the flat and rigid one;

(3) The length of the anchor thread reveal is between 25~40mm, and the anchor should be perpendicular to the coal and rock surface; the centerline of the jack axis articulating rod anchor body is common;

(4) Pressurization should be viewed before the force gauge defect-free condition (operating medium pipeline pressure gauge twisting jack, etc.);

(5) anchor dynamometer pressurization should be uniform and slow, until the anchor loosening or pressure gauge readings to the anchor design anchorage force value that is aborted, generally not for destructive testing;

(6) jack unpressurized, slowly release the switch twist;

(7) Pressure test, the neighboring 3m of the tested anchor shall not be occupied;

(8) If the resin anchor is measured half an hour after the installation, the measured value should be multiplied by a factor of 1.3;
