Characteristics of non-excavation works Compared with other technologies, non-excavation technology started relatively late. However, it is worth noting that in the past 20 years, the non-excavation technology has developed significantly both in theory and in construction technology. Non-excavation technology is a very important construction method for urban paving pipelines. The use of non-excavation technology to lay pipelines has several unique advantages.
Non-excavation technology has been widely used abroad and is gradually becoming popular in China. It is a construction method that can safely and effectively carry out environmental protection without digging the ground, passing through roads, railways, rivers, and even under the building.
The non-excavation technology does not excavate the ground, so the upper soil layer of the pipe to be laid is not disturbed, and the pipe joint end of the pipe is not easy to produce step deformation, and the pipe life is also greater than that of the excavation method.
The use of under-stolen trenchless technology can save a large amount of land acquisition and demolition costs, reduce the use of relocated houses, shorten the length of pipelines, and has great economic benefits.

The main purpose and scope of application of the shackle: The shackle can be used for the end fittings of the rigging, and is directly connected to the object to be lifted during the lifting operation. Shackles can be used between rigging and end fittings, only for connection. When the rigging is used in conjunction with the beam, the shackle can be used to connect the rigging with the lug plate at the lower part of the beam instead of the lifting ring, which is convenient for installation and disassembly. Shackles are widely used connection tools in lifting operations, and are mainly used for connection parts that are often installed and disassembled in hoisting. D-type shackle is mainly used for single-limb rigging; B-type shackle is mainly used for multi-limb rigging.
