The Technology of Ground Anchor System

The Technology of ground anchor system mainly refers to anchor bolt in stratum linking structures with rock soil body, transmitting structures’ tensile force or reinforcing rock soil body by relying on anti-shearing strength to keep stable of structures and rock soil body. Comparing with traditional methods of totally relying self intensity and gravity to make […]

Mechanical Behavior of Self Drilling Rock Bolt’s Load Transfer

The main function of self drilling rock bolt in concrete structure is bear tensile force to cover poor performance of tensile strength and shortage of ductility. Structurally, self drilling rock bolt is divided into anchorage section in rock body, free section between rock body and free section in concrete. Intense water pressure between concrete and […]

Geotechnical Engineering Investigation of Subway

Subway is short for underground railway, referring to urban rail transport system working underground. While in actual, some lines of subway will be laid ground because of construction environment. The purpose of investigating geotechnical engineering is to ascertain engineering geological condition and hydrogeological condition along the subway and auxiliary project, helping to provide basic data […]

Applicable Strata and Advantages of Hollow Bar Anchor

Generally speaking, hollow bar anchor is suitable for all the strata that retaining wall and soil nail wall and also the prestressed cable bolt can apply to . For the anchoring technology which has drilling operation requirements, drilling is usually the most critical process and directly affect the bearing capacity of the hollow bar. Drilling […]
