The mass data in whole process of physical model test were real-time recorded; and the implementing mechanisms, reinforcement efficiency, construction technology of new horizontal flexible reinforced grouting technology were studied with physical model test in field.

Combining two cases,the design and construction of dealing with defects in two different types of drilled piles with pressured grout and reinforcements are presented The improved results are also discusse

Grouting reinforcement design and construction of old roads;

Karst roadbed grouting reinforcement construction technology

In order to make clear the effect of grouting reinforcement of broken rocks,grouting reinforcement test of post-peak rock sample was made and then the sample was tested by adopting cement slurry and Malisan N,respectively.

This paper introduced the two-step coupled grouting method to consolidate the joint,and achieved better results.

Based on similar theory,the deformation properties of-440 pump with high rheological Surrounding Rock are studied by similar material experiment ungrouting and postgrouting at Wannian Coal Mine.

This paper analyses the disease origin in new subgrade of the sixth speeding-up in Jing-Guang Line,proposes the measure of static press grouting in subgrade projects,and introduces in detail the subgrade strengthening plan and construction techniques.

This paper presents blasting grouting consolidation technology and "U" Shaped conduction cave blasting drilling technology applied in fault zones, which result in a safe, quality and efficient effect in construction.

Combined with engineering example,the foundation was consolidated by deep layer agitating cement pile and grouting,its grouting consolidation technology and agitating pile consolidation technology were illustrated.
