The soil nailing wall is a kind of technology for supporting and strengthening the in-situ soil. The soil nails are integrated with the soil around tightly, so that they can form into a type of composite soil, relying on the frictional force of contact surface. Based on the analysis of the constructional scheme of the national stadium, the key factors for controlling the quality of the construction were found. The quality system during the project should be managed strictly. And the diameter, length and strength of the anchorage ought to be executed exactly. This scheme provided reasons for the national stadium’s soil nailing wall’s safety and quality assurance.

Sinorock focuses on every detail to assure that their products are high quality soil nailing systems.

Details in material

To produce high quality soil nailing 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.
