In the controlled demolition of a reinforced concrete water tower, the method consists of opening window (including directional window), cutting reinfovced bars, keeping strut pieces and then demolishing it totally,The method has many adventages——increased free surface, ensuring the tower to be collapsed in proper direction, controlled fly rocks and reduced vibration. For weakened area of load-bearing, steady ability should be calculated to ensure safety in construction practice.At the same time,...

In the controlled demolition of a reinforced concrete water tower, the method consists of opening window (including directional window), cutting reinfovced bars, keeping strut pieces and then demolishing it totally,The method has many adventages——increased free surface, ensuring the tower to be collapsed in proper direction, controlled fly rocks and reduced vibration. For weakened area of load-bearing, steady ability should be calculated to ensure safety in construction practice.At the same time, it is necessary to examine overturn and anti-overturn to define cutting-mouth parameters correctly.

采用“开窗口(包括定向窗)、切钢筋、留支撑块”方法进行钢筋混凝土水塔定向爆破拆除,可增加爆破临空面,保证倒塌方向准确。对控制飞石、震动起到一定作用。但因承载截面减弱,必须进行稳定性计算,确保施工安全。同时还应进行倾复与抗倾复检算,以确定切口参数选择正确。

A 53m high chimney with two layers of lining,situated on a hill in the city, is slanting due to its rupture at the upper end. A dierctional controlled blasting was used to demolish the chimney through reasonably selecting the collapse direction and pre demolishing the insulating layer and lining, the technological programs of opening a directional window and blasting the wall and lining at once are adopted.
