Mechanical Research and Optimization of the Design of an Umbrella-Shaped Enlarged-Head Hollow Grouting Bolt with an Expansion Pipe

Mechanical Research and Optimization of the Design of an Umbrella-Shaped Enlarged-Head Hollow Grouting Bolt with an Expansion Pipe

In geotechnical engineering, traditional anchor bolts often have problems such as an insufficient bearing capacity, their ease of loosening, and an unsatisfactory support effect under complex geological conditions (such as soft soil or broken surrounding rock), resulting in it being difficult to gua...
