Description

Technical Field

[0001] The utility model relates to the technical field of plug blasting, in particular to a charge installation device for plug blasting in a low-temperature environment. Background Technique

[0002] Plug blasting is a blasting technique used when constructing a tunnel water inlet below the normal water level of a reservoir or natural lake. This technique forms an inlet that meets the design requirements by blasting away the reserved rock (figuratively called a plug) at the water inlet part in one blast. The following is a detailed analysis of plug blasting: The plug blasting technique originated in the 19th century. In 1877, Chile first announced the use of the plug blasting technique. Since then, this technique has been widely used globally, especially in water conservancy project construction. The main advantage of plug blasting is that it can avoid building a construction cofferdam, making the construction period not restricted by seasonal and water level changes, thus improving construction efficiency. Excavating and lining the tunnel: First, carry out the excavation work of the tunnel and carry out lining during the excavation process to ensure the stability and safety of the tunnel. Reserved plug: Reserve a certain thickness of plug at the tunnel water inlet part as a water retaining structure to prevent water from flowing into the tunnel during construction. Construction of the tunnel body and gate shaft: After the completion of projects such as the tunnel body and gate shaft, the next blasting preparation work can be carried out.
