Difference between pipe seam anchors and ordinary anchorsPipe seam anchors and ordinary anchors differ in structure, construction and application. Pipe seam anchors are mainly composed of anchor rods, anchor tubes and endurance tubes. The anchor rods are made with smooth surfaces and slits are cut in the anchor tubes, while the structure of ordinary anchors is more diversified.

Principle analysis of the collapse reduction effect of left-handed anchorsIf the unstable rock layer of the vault is regarded as the combined beam (plate) supported by the side wall, because the anchor hanging on the stable surrounding rock can be regarded as the fulcrum, the installation of left-handed anchor without longitudinal ribs is equivalent to adding the fulcrum, reducing the support span, and then reducing the bending stress and deflection of the support to maintain the stability of the support and the rock, so that the rock is not easy to deform and damage.

33mm Split Tube Seam Anchor AdvantagesAs a kind of rock support equipment used in underground mining and civil engineering projects, 33 mm pipe seam anchor shows many advantages in engineering practice. First of all, its high load-bearing capacity is one of the main features of this anchor.

Factors affecting the quality of anchor tray determinations(1) Environmental temperature change, due to thermal expansion, the balance of the unequal arm and other reasons, will make the balance of the zero point and the equilibrium point of change, the value of the occasional deviation can be up to a number of times the balance of the sensibility. Thus, the balance room should be a constant temperature, first-class, second-class standard balance and first and second-class laboratory balance should be 20 ℃ ± 2 ℃ under the conditions of work, the accuracy of a little lower to reach 20 ℃ ± 5 ℃.

Common sense maintenance of right-handed equal-strength threaded anchorsTo introduce you to the maintenance of right-handed equal-strength threaded anchors: Mining anchors have irreplaceable advantages compared with traditional metal anchors.

Difference between left-handed anchor and right-handed anchorCharacteristics of left-hand anchor:Left-hand threaded steel anchor without longitudinal rib resin anchor anchor high strength, reasonable structure, preload, can automatically adjust the direction of force, increase the binding force on the surrounding rock, can realize the mechanization of rapid installation of the left-hand anchor Advantages of left-hand anchors:High strength of the anchor, reasonable structure, preload, can automatically adjust the direction of force, increase the binding force on the surrounding rock, can realiz

Shandong anchor manufacturer produces anchor is a kind of anchor, active reinforcement of the surrounding rock of the new anchor. Before hitting the anchor, we Should knock on the gang to ask the top, the loose rock block block diao exhaust, deal with the dangerous rock. Check whether the width and height of the roadway meet the requirements, and the undigging roadway that does not meet the requirements should be reworked to meet the requirements before anchoring.

Ruiyu Company Organizes Emergency Rescue Knowledge TrainingIn order to protect the safety of employees and pay attention to their health condition in real time, Rayou Company has equipped workshops with special first-aid medicine boxes, blood pressure monitors, patchouli, quick-acting heart pills and other medical and healthcare supplies, and has established a relevant medical apparatus management system and processing procedures to facilitate the workshops to make temporary rescue treatment when the employees' health emergencies occur.
