Grouting (Injection Grout), also known as Grouting, mainly includes Static Pressure Grouting and High Pressure Jet Grouting, widely used in water conservancy and hydropower, transportation, construction, mines Rock and soil reinforcement and anti-seepage in engineering, as well as commonly used technical means for slope protection, sand slide protection, and water and soil conservation in geological disaster management and geological environmental protection. Trenchless technology (Trenchless Technology or No-Dig) is to detect, lay, repair or replace underground pipelines under the condition of micro-excavation or no excavation. It has many open-cut methods without damaging the surface environment and without affecting ground traffic. With incomparable technical advantages, it is an environmentally friendly new technology for underground pipeline construction with great development potential. Drilling & Tunneling, including two aspects of drilling/well (Drilling) and tunneling (Tunneling), is to break the rock and soil layer by mechanical, chemical and other means, so as to form a borehole or hole with specifications and quality in the rock and soil mass. Tunnels are used to explore and develop mineral resources (including natural gas hydrate, shale gas, oil shale and other unconventional energy sources), obtain rock (mine) cores and ice cores, disaster prevention and early warning, and implement engineering construction. Oil & Gas Storage and Transportation (Oil&Gas Storage and Transportation) is the link connecting oil and gas production, processing, distribution and sales, mainly including oil and gas field gathering and transportation, long-distance transmission pipelines, storage and handling, and urban transmission and distribution systems. Lifeline Engineering is an engineering system that is closely related to people's lives and has a significant impact on social life and production, such as transportation, communication, water supply, drainage, power supply, gas supply, and oil transportation. Underground Pipe Gallery (Underground Pipe Gallery), that is, the underground urban pipeline comprehensive corridor, is a structure and ancillary facilities built underground to accommodate two or more types of urban engineering pipelines.
