Grouted Bolts-manufacture,factory,supplier from China

Background on Hollow AnchorsTo better understand the mechanics involved in load transfer between anchors and mine rock, the Bureau of Mines initiated a program to study the load transfer mechanics of passive, fully grouted hollow anchors. This work was accomplished in support of the Bureau's goal of improving the underground safety of the nation's miners. The first phase of the study was conducted in the laboratory to examine the linear, nonlinear, and time-dependent behavior of anchor rods under varying load conditions.

Ruiyu Company Held a Lecture on Rebar Anchor and Mining Anchor BoltsIn order to further promote the in-depth development of the activity of “Year of Improving the Grassroots Basis of Safety Production”, enhance the awareness of life safety of the whole staff, and create a strong safety propaganda atmosphere, Ruiyu held a speech contest with the theme of “Fear of Life, Safe Development, Starting from Me” on the morning of Nov. 26th. On the morning of Nov. 26, Ruiyu Company held a speech contest with the theme of “Respect Life, Safe Development, Starting from Me”.

Promote the greening of the manufacturing industryBy 2030, the output value of green factories at all levels will account for more than 40% of the total output value of the manufacturing industry; by 2030, the recycling volume of major renewable resources will reach 510 million tons, and the comprehensive utilization rate of bulk industrial solid wastes will reach 62% ......

The company is about to participate in the International Mining Exhibition in Novokuznetsk, Russia, June 4-7, 2024

Shandong Ruiyu Company Solidly Carries Out “Safety Production Month” ActivitiesRuiyu Company closely follows the theme of “Strengthening Red Line Awareness and Promoting Safe Development”, increases safety publicity and education, strengthens the awareness of “red line”, and strictly abides by the “bottom line”.

2024 Autumn Expansion “Group Building Activity”On October 28th, Ruiyu Branch carried out the “2024 Autumn Expansion” group building activity, which was held in Ruyi Valley with the intention of relaxing oneself, adjusting the body and mind, and working together to help each other in the activity, promoting the relationship and cooperation ability of each department, and achieving the future together with an open and enthusiastic mind.Fun GamesIn the team game, everyone randomly formed a group to get points for their own team.

Shandong Ruiyu Company Solidly Carries Out the Activities of Rule of Law Awareness MonthFrom April 1 to 22, Ruiyu Company organized and carried out rule of law publicity and education activities with the theme of “enhancing the concept of rule of law and promoting the rule of law”.Firstly, by posting cartoon version of the Constitution publicity wall charts on the bulletin boards, the company publicized the concept of supremacy of the Constitution and rule of law according to the Constitution in an easy-to-understand way, publicized the basic rights and obligations of citizens, safeguarded the

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.

The main factors of integrity and stability of anchor supportThe put into use of anchor rods eliminates the hidden dangers in safety production to a certain extent and reduces the labor intensity of workers.

Linkage between pullout force and distance distribution of anchor disk with anchorsGeotechnical anchoring skill is an important part in the field of geotechnical engineering, and it has a wide range of applications in the fields of hydraulic construction, towering structure, underground engineering, anti-slip engineering and slope engineering.
