Dismantling method of river-crossing double-cantilever aqueduct structure
The invention provides a dismantling method for a river-crossing double-cantilever aqueduct structure. The dismantling method comprises the following steps that firstly, blasting sections are divided; the aqueduct structure is divided into a left blasting section, a river-crossing blasting section and a right blasting section from left to right; 2, dividing blasting areas of all the blasting sections; thirdly, blast holes in all the blasting areas are constructed; step 4, charging explosives in each blast hole and installing a detonating element; 5, mounting a detonating network of each blasting section; step 6, detonating; the river-crossing blasting section is firstly detonated, then the left blasting section and the right blasting section are detonated by adopting a delayed detonating technology, the detonating direction of the left blasting section is from left to right, and the detonating direction of the right blasting section is from right to left; and 7, checking after explosion. According to the method, the construction efficiency of dismantling the river-crossing double-cantilever aqueduct structure is improved.
本发明提供了一种跨河双悬臂渡槽结构的拆除方法，其包括如下步骤：步骤一：爆破段划分；将渡槽结构从左至右划分为左侧爆破段、跨河爆破段和右侧爆破段；步骤二：各爆破段的爆破区划分；步骤三：各爆破区炮孔施工；步骤四：在各炮孔内装药并安装起爆元件；步骤五：各爆破段起爆网路安装；步骤六：起爆；先起爆跨河爆破段，然后采用延时起爆技术起爆左侧爆破段和右侧爆破段，左侧爆破段的起爆方向为从左至右，右侧爆破段的起爆方向为从右向左；步骤七：爆后检查。本发明提高了跨河双悬臂渡槽结构拆除的施工效率。
