Drawings
Fig. 1 is a schematic structural view of a foundation trench construction dust-settling device of the utility model;
the device comprises a sliding rail 1, an arched beam 21, an upright column 22, a spherical end 221, a through long connecting rod 23, a shear support 24, a tarpaulin 25 and a spray fan 3.
Detailed Description
As shown in fig. 1, a foundation trench construction dust-settling device comprises two slide rails 1 which are respectively arranged at two sides of a foundation trench along the length direction of the foundation trench, and a sunshade which is slidably arranged on the two slide rails 1;
the sunshade comprises an upright post 22 arranged on the sliding rail 1 in a sliding way, an arch beam 21 erected on the upright post 22 and tarpaulin 25 covered on the arch beam 21, wherein spray fans 3 with outlets facing to the base groove are respectively arranged below the arch beam 21 and on the inner side of the upright post 22, and the spray fans 3 are communicated with a water supply network through pipelines; the atomizing fan 3 is a common outdoor labor protection cooling article, fine water mist is sprayed out through an atomizing nozzle, then the fan blows the water mist to workers in the labor, the air containing fine mist drops is kept at the wet bulb temperature which is lower than the air temperature, and therefore the heatstroke prevention cooling effect is achieved. Meanwhile, air containing fog drops can be adhered with dust, and the effect of dust fall is achieved.
The sunshade and the working surface of the base groove are arranged above the working surface in a one-to-one correspondence manner. Because the foundation ditch is interior for the construction progress, probably need two-way or even multidirectional construction, have a plurality of working faces, for heatstroke prevention cooling and dust fall, all should set up the sunshade on every working face.
The arched beams 21 are truss beams and are arranged at intervals along the length direction of the slide rails 1, and two ends of each truss beam are respectively erected on the two slide rails 1 through upright posts 22; the slide rail 1 is a channel steel with an upward opening, and the lower end of the upright post 22 is arranged in the channel steel opening in a sliding manner; the upper ends of the upright posts 22 positioned at the same side of the base groove are respectively and fixedly connected with a through long connecting rod 23 parallel to the slide rail 1. The truss girder is a light steel truss girder, has higher strength than a ceiling of a conventional awning, and can meet the requirements of hoisting the spray fan 3 and the water pipe. The wind end plates can be arranged at the two ends of the channel steel to prevent the awning from being separated from the two ends of the slide rail 1.
The spraying fans 3 are arranged at intervals along the length direction of the upright posts 22 and the arched beams 21, and the distance between two adjacent spraying fans 3 is not more than two meters. If the distance is too large, dust may overflow from the gap.
And a cross brace 24 is arranged between the adjacent upright posts 22 positioned on the same side of the base groove, and the cross brace 24 is fixedly connected with the two adjacent upright posts 22 respectively so as to enhance the rigidity of the whole sunshade and prevent the sunshade from deforming.
The spherical end 221 is anchored at the lower end of the upright post 22, the teflon coating is coated on the inner surface of the slide rail 1, and the wheel is not arranged at the lower end of the upright post 22, so that various impurities can enter the slide rail 1 to influence the movement of the wheel in the construction process of a construction site, and if the wheel is adopted, the wheel with a larger diameter is used, the wheel shaft of the wheel is higher than the slide rail 1, and the bearing on the wheel shaft is a sealed bearing.
The slide rail 1 is fixedly connected with the supporting structure of the foundation trench to strengthen the supporting structure of the foundation trench and prevent the slide rail 1 from moving randomly.
The utility model relates to a foundation trench construction dust device, its use includes following step:
the method comprises the following steps: after earth excavation of a shallow layer of the foundation trench and construction of a supporting system are finished, installing sliding rails 1 on two sides of the foundation trench and connecting the sliding rails with the supporting system of the foundation trench;
