HohhotHouse demolition and reconstruction servicesStatic blasting demolition: Blast the surface of the supporting beam with a pneumatic hammer, cut the stirrups, then drill holes in the beam with an expansion agent added. After reaction, it expands to crack the beam, then blast and fragment it, and finally clean up. Advantages include minimal restrictions, safety, easy cleanup, and moderate costs; disadvantages are slow construction speed and the need for a large workforce. Cutting: Cut the supporting beam into blocks using cutting methods, hoist them down to the edge of the foundation pit or transport to the location, and recycle the broken steel bars. The limitation of cutting removal is that a large crane can be placed around the foundation pit. Its advantages are fast construction speed, cost-effectiveness when using accelerated construction methods, and the ability to place a large crane; disadvantages include high site requirements (where cranes need to be placed) and difficult transportation (if not able to be stacked and crushed on-site).

Inner MongoliaDemolition of破碎房屋servicesCombination of Cutting and Static Crushing Demolition: For foundation pits where large cranes can be partially placed but with local limitations, the simultaneous execution of mechanical cutting and static crushing can be adopted. This method not only shortens the construction period but also has low requirements for the number of personnel in the cutting and crushing shifts. Beam Removal: Generally, it is recommended to use the static method for beam removal, as the beam is connected to the continuous wall on one side. If the cutting method is used, the cost will be high.
