Blasting demolition method for frame structure with small height-width ratio
The invention discloses a blasting demolition method for a small-aspect-ratio frame structure, which comprises the following steps of: marking mechanical broken parts of the last row of upright posts of the small-aspect-ratio frame structure, and dividing the upright posts into a damaged area and a reserved area; the concrete protection layer in the stand column damage area is broken, and the steel bars are exposed; the steel bars exposed in the damaged area are cut off; the remaining core concrete in the damaged area of the stand column is broken till the marked damaged area on the stand column is completely broken through; a trapezoidal or triangular blasting notch is formed in the frame structure with the small aspect ratio in the dumping direction with the position where the second last row of stand columns are located as the supporting point of structure dumping, and blast holes are formed in the stand columns, cross beams and other components within the range of the notch. And charging and detonating in the blast hole. According to the method, the workload of blasting demolition pretreatment can be reduced, the use amount of blasting materials in blasting engineering is reduced, blasting vibration is reduced on the premise that the engineering quality is ensured, the blasting cost is reduced, the construction period is shortened, and the method is suitable for frame structures made of various materials and used for multiple purposes.
本发明公开一种小高宽比框架结构的爆破拆除方法，标出小高宽比框架结构最后一排立柱机械断开部分，将立柱分为破坏区域及保留区域；破碎立柱破坏区域内的混凝土保护层，暴露出钢筋；割断破坏区域内暴露出的钢筋；破碎立柱破坏区域内剩余的核心混凝土，直至立柱上标出的破坏区域被完全打通；在小高宽比框架结构内，沿倾倒方向，以倒数第二排立柱所在位置为结构倾倒的支点设置梯形或三角形爆破切口，并在切口范围内的立柱、横梁等构件上布置炮孔；在炮孔内装药起爆。本发明能够减少爆破拆除预处理工作量，降低爆破工程中爆破器材使用量，在确保工程质量的前提下减小爆破振动、降低爆破成本、加快工期，而且适用于多种材质、多种用途的框架结构。
