Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a sinking fence used in a construction site. Background Art

[0002] At present, construction sites are mostly accompanied by a large amount of dust. This dust not only affects the appearance of the city, but also affects the health of our staff. If the dust density is too high, it will also affect the vision of the staff, which may cause accidents. At the same time, during construction on the construction site, most of the construction sites will be enclosed by fences to play a protective role. However, most of the fences currently used are formed by welding multiple horizontal columns and vertical columns. If the equipment is being transported and needs to pass through the fence, it can only pass through by giving way, which directly causes low efficiency. Utility Model Content

The water inlet connecting valve is communicated with one end of the water guide cavity, and each atomizing nozzle is communicated with the water guide cavity.

[0006] Furthermore, the length direction of the water-conducting cavity is consistent with the length direction of the bottom beam, and the atomizing nozzles are arranged in sequence along the length direction of the water-conducting cavity.

[0007] Furthermore, the water inlet connecting valve is connected to an external water source.

[0010] Furthermore, a valve installation hole is provided on the bottom beam, and the water inlet connecting valve is detachably sealed and arranged in the valve installation hole and is communicated with the water guiding cavity.

[0011] Furthermore, a plurality of nozzle mounting holes are provided on the upper surface of the bottom beam, each nozzle mounting hole corresponds to each atomizing nozzle one by one, and each atomizing nozzle is installed in the corresponding nozzle mounting hole.

[0012] The beneficial effects of the technical solution provided by the embodiments of the utility model are as follows: a sinking fence for a construction site of the utility model can be constructed by pulling out each railing, so that each railing can be directly pulled out when it is necessary to pass through the fence without taking a detour; at the same time, each atomizing nozzle can effectively remove dust on the construction site.
