Trenchless technology has gained significant recognition and application in the construction of urban underground pipelines in China, driven by both market demand and the economic and social benefits it offers. This technology allows for the installation and repair of underground utilities without the need for traditional excavation, making it ideal for busy urban environments where road disruption is undesirable.
The development of trenchless technology in China can be divided into three key phases. In the early 1970s and mid-1980s, special situations often prevented road excavation, such as on Beijing’s East and West Chang’an Street. These circumstances forced construction companies to adopt non-excavation methods for pipeline installation, which helped lay the foundation for modern trenchless technology in the country.
The second phase, from the mid-1980s to the mid-1990s, marked the introduction of specialized equipment. As China's economy grew rapidly due to reform and opening up, investment in urban infrastructure surged. The demand for communication cables, fiber optics, and TV lines increased significantly, leading to a surge in pipeline projects. To meet these challenges, China began importing trenchless technology and equipment from abroad, marking a major step forward in the industry.
The third phase, starting in the early 1990s, saw the rise of independent development. As trenchless technology became more widely known, the domestic market began to show optimism, leading to increased R&D efforts for small and medium-sized equipment. Companies started exploring various applications of this technology, and specialized engineering firms focused on trenchless pipeline construction began to emerge.
Experts emphasize that the development of the trenchless industry involves two critical components: trenchless pipeline construction techniques and the associated equipment. Research into construction methods not only shapes the direction of equipment development but also defines the essential performance requirements for such tools. It serves as the material basis for implementing innovative technologies and processes.
After initial project development, engineering demonstrations, and market cultivation, China has begun to establish a new industrial prototype for trenchless technology. Companies are now setting up their own design and development bases, producing a range of equipment. Major construction machinery is being developed comprehensively, and specialized engineering firms have emerged, entering various fields of trenchless pipeline engineering.
However, compared to global standards, China's trenchless industry is still in its early stages. First, trenchless technology has been well-established and supported by governments abroad, becoming a high-tech sector with broad societal acceptance. Second, China's development remains uneven, particularly in areas like pipeline replacement. Third, there is a lack of sufficient investment in new equipment development, and the scope of research is still limited.

Buffer ring is a common Machine element, which is used to reduce the vibration and noise generated during the operation of the machine. Buffer rings are mainly divided into two types: rubber buffer rings and spring buffer rings. Rubber buffer rings are suitable for low-frequency vibration and impact, while spring buffer rings are suitable for high-frequency vibration and impact. Buffer ring is an important Machine element, which is widely used in automobile, machinery, electronics and other fields.
