摘 要:某地下室改造项目有大量的砌体工程,由于没有地下室汽车跑道,砌块等散状物料无法直接用车辆运输至地下室,必须进行二次转运。常规的人工搬运、或机械吊运、或斜坡溜槽等方法均费时费工,易扬尘,砌块破损率较高。本文阐述了项目研发的一种防碎裂的垂直运输装置施工技术,利用能就地取材的钢管和扣件搭设支撑架体,将柔性橡胶波纹管固定安装在支撑架体上,柔性橡胶波纹管一端穿过地下室顶板洞口作为进料口,另一端作为出料口,且可通过调整柔性橡胶波纹管的弧度和在出料口箍绑防冲击麻袋,对砌块等散状物料滑出出料口的速度和冲击力起到缓冲作用,从而降低砌块的破损率。这种防碎裂的垂直运输装置施工技术的成功应用,加快了地下室改造的施工进度,抑制了扬尘现象,降低了材料运输的损耗,节约了施工成本,值得在类似工程项目中进行推广应用。A basement renovation project has a large number of masonry works,because there is no basement car track,the bulk materials such as blocks cannot be directly transported to the basement by vehicle,and secondary transport must be carried out.Conventional manual handling,mechanical lifting,or slope chute and other methods are time-consuming,easy to dust,and the block breakage rate is high.This paper describes an anti-fracture vertical transportation device construction technology developed by the project.Supporting frame body is set up by using locally available steel pipes and fasteners,and flexible rubber bellows are fixed on the supporting frame body.One end of the flexible rubber bellows passes through the roof hole of the basement as the inlet,and the other end serves as the outlet.By adjusting the curvature of the flexible rubber bellows and tying the anti-impact sack in the discharge port,the speed and impact force of the loose materials such as blocks sliding out of the discharge port can be buffed,so as to reduce the breakage rate of blocks.The successful application of a kind of anti-fragmentation vertical transportation device construction technology speeds up the construction progress of basement reconstruction,inhibits the dust phenomenon,reduces the loss of material transportation,and saves the construction cost.It is worth popularizing and applying in similar projects.
