Slurry Shield Method of Constructing Underwater Slope Foundation
In the past few years, the slurry shield method has become increasingly popular with engineers constructing underground slope foundations. This method, also known as sprayed concrete or shotcrete, uses a pressurized series of pumps ......
radioactive prospecting
Introduction
Radiological exploration is a technique used to analyze and assess the composition of soils and bedrock underlying the surface. It is a non-destructive method that can be used to identify the hydrological, geological and geophysical characteristics of the subsurface. There are variou......
rock drillability
Rock Drillability Rock drillability is the ability of rocks to be drilled or mined using a drilling machine, such as a jackhammer or rotary drill. It is an important property that affects rock fragmentation, excavation methods, drilling and blasting operations, and other applications in the mining ......
Trough construction
Mining Ponds Construction
Mining ponds are essential for the safety, performance and environmental protection of a mine. The construction process needs to ensure that all the environmental and safety regulations are followed, and that any potential impacts on the neighboring communities and resou......
Polymer heavy metal trapping and precipitating agent--Dtcr
Polymer Metal-Chelation Precipitant Dtcr
Polymer Metal-Chelation Precipitant Dtcr (Dtcr) is an effective and robust approach to capture and remove metal ions from aqueous solution streams prior to treatment or final discharge. By forming nano-sized chelates, Dtcr offers superior removal of trace ......

Concrete pump can not pump the treatment
Concrete Pumping: What You Can’t Pump
Concrete pumping is a convenient and efficient way to transport concrete quickly and effectively over long distances. It is also one of the safest and most cost-effective methods available, as it requires less manpower and a minimal amount of material handli......
Deep foundation pit support
Deep Foundation Pit Support
DEEP foundation pit support involves a range of techniques used to reinforce the sides of deep excavation sites. Under certain geological conditions, the soil around the sides of an excavation can become unstable, leading to caving and other structural supports. To avo......
