Building foundation pit guardrail realizing spraying dust reduction
The invention discloses a building foundation pit guardrail realizing spraying dust reduction. The building foundation pit guardrail realizing spraying dust reduction comprises a vertical rod fixedlyconnected to the upper end of a base, a plurality of trumpet-shaped air suction cavities are evenly formed at the upper end of the vertical rod, vibration sheets are fixedly connected to the inner walls of the air suction cavities, a plurality of air storage cavities with the number equal to that of the air suction cavities are evenly formed in the inner wall of the vertical rod, the inner walls of the air suction cavities are connected with the air storage cavities through one-way air outlet cavities, and a one-way air suction pipeline communicating with the upper end of the vertical rod is arranged on the inner wall of each air suction cavity. The vibration sheets can protrude to different degrees under the action of sounds of different frequencies generated when facilities around a foundation pit work, then air in the air suction cavities enters the air storage cavities to be stored, when the pressure intensity of the air stored in the air storage cavities reaches the pressure valueof each pressure relief valve, high-pressure air can be sprayed out of air outlet pipelines, thus water in each capillary tube is extruded into each air outlet pipeline and torn into water mist to besprayed out, and then dust in the air is reduced.
本发明公开了一种喷雾降尘式建筑基坑护栏，包括固定连接在底座上端的立杆，所述立杆上端均布开设有多个呈喇叭状的吸气腔，所述吸气腔内壁固定连接有振片，所述立杆内壁均布开设有多个与吸气腔数量相等的储气腔，所述吸气腔内壁与储气腔通过单向出气腔连接，所述吸气腔内壁开设有与立杆上端连通的单向吸气管道。本发明通过振片可在基坑周边设施工作时产生不同频率音响的作用下做不同程度的凸起，使得吸气腔内的气体进入储气腔中储存，当储气腔内存储的气体压强达到泄压阀的压力值时，高压气体会从出气管道喷出，使得毛细管内的水分被挤压至出气管道中并被撕裂呈水雾喷出，对空气中的灰尘进行降尘。
