Dismantling method for concrete-filled steel tube arch bridge
The invention provides a dismantling method for a concrete-filled steel tube arch bridge. The dismantling method comprises the following steps that firstly, a blasting part is divided; 2, dividing blasting areas of all the blasting parts; thirdly, manual cutting is conducted; fourthly, blast holes in all the blasting areas are constructed; 5, charging each blast hole and installing a detonating element; sixthly, a transverse cutting rope is installed; a plurality of transverse cutting ropes are installed on the side walls of the third blasting area, the fourth blasting area, the fifth blasting area and the sixth blasting area; 7, mounting a detonating network; eighthly, transverse cutting ropes are used for cutting; ninthly, detonating is conducted; sequentially detonating from left to right or from right to left by adopting a delayed detonating technology; and 10, checking after explosion. The dismantling efficiency and safety of the concrete-filled steel tube arch bridge are improved.
本发明提供了一种钢管混凝土拱桥的拆除方法，其包括如下步骤：步骤一：爆破部分划分；步骤二：各爆破部分的爆破区划分；步骤三：人工切割；步骤四：各爆破区炮孔施工；步骤五：在各炮孔内装药并安装起爆元件；步骤六：安装横向切割索；在第三爆破区、第四爆破区、第五爆破区、第六爆破区的侧壁上安装多道横向切割索；步骤七：起爆网路安装；步骤八：横向切割索切割；步骤九：起爆；采用延时起爆技术从左至右或从右至左依次起爆；步骤十：爆后检查。本发明提高了钢管混凝土拱桥拆除的效率和安全性。
