Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a dust suppression system used for excavation construction of urban narrow and long unsupported deep foundation pits. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction regulations. For those with deep excavation and nearby buildings, the foundation pit wall support method, shotcrete retaining wall method, and large foundation pit even adopt methods such as undergroun...
