Sinorock has strict material inspections for producing high quality anchor bolt system

Le 18 September 2016, 10:59 dans Humeurs 0

Sinorock, the most professional supplier in the geotechnical engineering and construction industries. We are eager to be the international leading anchor bolt manufacturer and supply a comprehensive range of anchoring system.

Except the main products: self drilling anchor bolt, anti-corrosion rock bolt,Sinorock also develops some related products, such as rock drill, anchor net, injection pump and so on. 

The products in Sinorock is powerful, reliable, excellent, professional and creative. They have the advantages of adapting to different rock conditions.

1.The self drilling anchor bolt is integrated with the functions of drilling, grouting and anchoring, it can ensure the anchoring for complex ground conditions.

2.The anti-corrosion rock bolt includes hot-dip galvanizing anchor bolt and stainless steel anchor bolt, they have the surfaces of good anti-corrosion materials and can prevent the chemical etching and rusting.

3.Rock drill, anchor net and injection pump are the complementary products which are combined with the anchor bolt and have better supporting effort.

If Sinorock want to be the leading anchor bolt manufacturer, the moment products are far from the times’ demands, what we should do is to improve our system, research and develop new technology, and perfect our service. Where there is faith, there is a way.

For improving the competitive power, Sinorock focuses on every detail to assure that their products are high quality anchor bolt systems.

To produce high quality anchor bolt system, the raw and processed material is one of the most important parts. Sinorock has a series of strict inspections for their raw materials when purchasing into their factory.

First, when purchasing agents buy seamless steel tubes back, godown keeper will check the material first, and purchasing agents fill in the arrival notice.

After seamless steel tubes are put in storage, inspectors will check the quality certificate of seamless steel tubes and steel rods.

Then, inspectors will sample and inspect these seamless steel tubes for these aspects: 

Surface and straightness. Check if the surface is smooth without burr fins, flaws or rubber adhesion. The sampling ratio is 50%.

Physical dimension. Measure external diameter, wall thickness and length with vernier calipers, wall thickness micrometer gauges and band tapes.

Mechanical property. Measure the extensibility and tensile strength with computer screen display hydraulic pull test machine.

The result of these measures should be filled in the arrival notice of seamless steel tubes. Only these tubes that are qualified can be put in storage.

In Sinorock, we have strict material inspections for producing high quality anchor bolt system.



Hollow self drill anchor system increased the stability in the working area

Feasible research, assessment and preliminary design will be also carried out. Construction quality ensures project security, so previous preparation work is necessary. Choosing suitable support measures to adapt for different geological conditions and guarantee project’s life time. Self drilling rock anchor is actually an effective one. It adopts different materials and processing technologies, with various sizes to suit for different geological conditions.

Hollow self drill anchor was also used for pre-support in in weak ground conditions. Hollow self drill anchor system increased the stability in the working area by transferring loads in the longitudinal direction and decrease excavation induced deformations. The system increased safety in the working area. Beside this standard usage, hollow self drill anchor is often applied to increase stability in portal sections and for the re-excavation of collapsed sections in underground construction. Another application area is ground improvement and waterproofing in combination with all tunnel construction methods.
