Dust fall system for urban long and narrow type support-free deep foundation pit excavation construction
The invention discloses a dust fall system for urban long and narrow type support-free deep foundation pit excavation construction. A foundation pit body is included. At least one of the two sides ofthe outer edge of an opening of the foundation pit body is provided with a shielding mechanism for pavement of dustproof net cloth towards the other side of the outer edge of the opening in the lengthdirection of the foundation pit body, a negative-pressure area for improving flow of air in the foundation pit body is formed between the dustproof net cloth and the outer edge of the opening of thefoundation pit body, guide rail assemblies which are in moving fit connection with the shielding mechanism are laid on the two sides of the foundation pit body in the length direction of the foundation pit body, and after the dustproof net cloth is laid and shielded, the two sides of the foundation pit body in the length direction of the foundation pit body are provided with a plurality of dust fall mechanisms for adsorbing and settling of raise dust in the foundation pit body, wherein the dust fall mechanisms are adaptive to the guide rail assemblies. According to the dust fall system, through the comprehensive means of shielding, adsorbing and settling, generation of raise dust is reduced to the maximum degree.
本发明公开了一种用于城市狭长型无支护深基坑开挖施工的降尘系统，包括基坑主体，在基坑主体的开口外缘两侧至少一侧设置有沿基坑主体长度方向向开口外缘另一侧铺设防尘网布的遮盖机构，在防尘网布与基坑主体的开口外缘之间形成一用于提高基坑主体内空气流动的负压区，沿基坑主体的长度方向在基坑主体的两侧分别铺设有与所述遮盖机构移动配合连接的导轨组件，以及与导轨组件适配的在防尘网布铺设并遮盖完成后，沿基坑主体的长度方向在基坑主体的两侧分别设置有多个用于对基坑主体内的扬尘进行吸附及沉降的降尘机构。本发明通过“遮盖+吸附+沉降”的综合手段，最大程度的降低了扬尘的产生。
