Slate belongs to the metamorphic rocks in the three major rock
types. It is generally formed by the metamorphism of mudstone of sedimentary
rocks. It has a plate-like structure a...
Soil nailing is a new technology used for foundation pit excavation
and slope reinforcement. Economical, reliable, quick, and easy construct, it
has been rapidly promoted and use...
In projects using self-drilling hollow bolts, it is inevitable to encounter geological conditions with soft and broken covering layers and hard rock layers. Under such geological c...
In recent years, self-drilling hollow grouting bolts have been more and more widely used in foundation and foundation engineering, tunnel and underground engineering, and slope eng...
The geographical restrictions of the deep foundation pit support
project are relatively large. When the deep foundation pit encounters a soft
soil layer, it will increase the pos...
A tunnel is a construction that is built underground, underwater, or
in the mountain by laying a railway or highway to let motor vehicles pass
through. Based on the site selectio...
For a long time, ordinary mortar bolts have
been widely used in geotechnical anchoring fields such as tunnels and slopes
due to their low cost. The advantages of the field are gr...

In
recent years, accidents occur frequently due to slope collapse, open-pit mine landslides,
and high slopes of highway engineering. So how to maintain the stability of the
slop...
The soil nail retaining wall is composed of the
reinforced soil body, the soil nail body placed in the soil, the protective

Rock bolt support is a very commonly used support method. Most of
its materials are steel materials. When supported, it is buried in the rock and
soil layer, so it will inevitabl...
In the construction of tunnels, some complex geological conditions, such as water-bearing rock masses, are sometimes encountered. If the water content of this rock mass is relative...
The stability of the high slope is mainly determined
by the geological conditions of the slope formed in the natural environment, as
well as the acquired artificial transformatio...
Weak and broken surrounding rocks are often encountered during
construction in tunnel engineering. Due to the nature of the rock mass itself,
the weak and broken surrounding rock...
