Hydraulic wire saws feature the following notable characteristics: reduced labor intensity, safe and reliable operation, overload protection, powerful power, enhanced cutting capability, and increased labor productivity. They are advanced equipment commonly used in demolition and dismantling construction projects. 1. Blasting Demolition: Drills holes in support beams using a pneumatic drill, sets explosives for blasting, and then manually and mechanically chisels and clears the concrete blocks. The advantages include fast construction speed, simple cleanup, and lower cost; however, the disadvantages include difficulties in handling related permits, significant impact on surrounding areas, and certain limitations.

Cutting and Demolition: Support the beams, then cut the beam into sections using a cutting method, and lift them with a crane to the foundation pit edge for crushing or transport to a designated location for crushing and steel recovery. The limitation of cutting and demolition is that there must be space for large cranes around the foundation pit. The advantages include rapid construction speed, suitability for projects with tight schedules, and relatively lower costs when large cranes can be used. The disadvantages are higher site requirements (a space for cranes is needed) and difficult transportation with high costs (if on-site storage and crushing are not possible).
