#Fully automatic control of dust-proof canopy of foundation pit#

Foundation pit dust-proof canopy is an innovative and efficient new construction dust control method, which effectively solves the contradiction between construction and environmental protection, not only facilitates construction operations, but also meets environmental protection requirements, and improves the working environment of the construction site.

In the construction work area, a "dust-proof sky curtain" system is formed by steel columns, steel wire ropes, motors and dust-proof nets, so as to achieve the effect of shielding dust. In addition to spraying, automatic cleaning, tight coverage, effectively reducing dust and noise and other pollution, this system has another outstanding feature: fully automatic and intelligent.

The opening and closing of the "dust-proof sky curtain" can be automatically controlled by electric buttons, instead of the traditional form of artificial covering net for dust coverage, and the remote control device can automatically open or close, and the entire foundation pit can be exposed in one minute.

At the same time, it has a self-balancing function, which is still safe and reliable in extreme weather such as strong winds and heavy rains. Because heavy storms and rains will increase the dynamic load of the dust screen support system, there are potential safety hazards, and the dust screen automatic control system can automatically retract in conjunction with strong winds and heavy rains.

There is about 10cm wide gap between each structural unit to avoid touching each other during the opening and closing process to prevent twisting and friction. At the same time, the canopy is raised by the steel structure supporting column, which provides a sufficiently high working space for the excavator to enter the construction site.

The single structural unit of the dust-proof sky curtain system is fixed on the foundation by the wire rope oblique pulling, with the wire rope as the slide, the wire ropes at both ends are the fixed wire ropes, through the semi-automatic device, the motor provides traction to control the rotation of the sliding wire rope, and the dust net is made of PVC The tube support is unfolded and connected with the steel wire rope through the sliding buckle, and finally the opening and closing of the dust-proof canopy is controlled by the motor, and each opening and closing takes only 40 seconds.

The application of the “foundation pit dust-proof sky curtain” system eliminates dust on the construction site, improves the construction standards of construction enclosures, strengthens civilized construction management, and continuously improves the level of construction refinement.

Above the foundation pit, the green dust screen forms a huge ceiling. There are several tow bars in the middle of these dust-proof screens, which can make the giant screen stretchable and retractable. When unfolded, the dust screen can tightly cover the top of the foundation pit, and after retracting, it can be completely unimpeded.
