In order to mitigate pressure or impact generated by demolition, provided is an expanding boom for a demolition water fire engine, which includes: a boom assembly where a plurality of booms formed in a tank type respectively is installed to be overlapped multiply; a support rail which is fixed and installed at an inner ceiling of a front side of a boom located at an outer side among a pair of booms adjacent internally and externally; a buffering block which is formed in a block shape, and has a combining groove combined and supported to be able to be slid along the support rail on an upper plane, and is installed to absorb impact between the inner ceiling of the front side of the boom located at the outer side and an upper plane of an outer side of the boom located at an inner side among the pair of booms adjacent internally and externally; and a slip member which is installed to reduce friction between a bottom of the buffering block and the upper plane at the outer side of the boom located at the inner side.
파괴에 의해 발생하는 압력이나 충격 등을 완화하는 것이 가능하도록, 각각 통형상으로 형성된 복수의 붐이 다중으로 중첩되어 설치되는 붐조립체와, 내외로 인접하는 한 쌍의 붐 중 바깥쪽에 위치한 붐의 선단쪽 내부 천정에 고정 설치되는 지지레일과, 블록형상으로 이루어지고 윗면에는 지지레일을 따라 슬라이드운동가능하게 결합되며 지지되는 결합홈이 형성되며 내외로 인접하는 한 쌍의 붐 중에서 바깥쪽에 위치한 붐의 선단부 내측 천장과 안쪽에 위치한 붐의 외측 윗면 사이에서 충격을 흡수하도록 설치되는 완충블록과, 완충블록의 저면과 안쪽에 위치한 붐의 외측 윗면 간에 마찰을 감소시키도록 설치되는 슬립부재를 포함하는 파괴 방수형 소방차용 신축붐을 제공한다.
