[0072] The environmental detection device is used to monitor the dust information at the construction site in real time.

[0073] Reference Figure 4 The system also includes a balancing device 600 for shock reduction of the first dustproof net assembly 320 and the second dustproof net assembly 420; the balancing device 600 includes a bracket 610, a container 620, a shock-absorbing rope 630, an elastic member 640, a connecting rod 650 and a limiting member 660, the bracket 610 is fixed to the first crown beam assembly 210; the container 620 is arranged on the top of the bracket 610; a through hole is opened at the bottom of the container 620, and the top is open; one end of the connecting rod 650 passes through the through hole and is fixedly connected to one end of the shock-absorbing rope 630, and the other end passes through the elastic member 640 and is fixedly connected to the limiting member 660.

[0076] Furthermore, a balancing device may also be provided on the second crown beam assembly 220, and the two balancing devices are connected by a shock absorbing rope 630, so as to further reduce the amplitude influence of the first dustproof net assembly 320 and the second dustproof net assembly 420 caused by the wind load, and the automatic balancing function is stronger.

[0077] The system also includes multiple water spraying devices, which are arranged around the sides of the foundation pit 30; the multiple water spraying devices are independently arranged and are all connected to the signal of the main control center, which can ensure that the site is moist during the large-scale excavation construction stage and effectively reduce the flying of dust.

[0078] A plurality of water spraying devices are arranged facing the earth excavation area, and each of the water spraying devices is arranged at equal intervals to form a water spraying and dust suppression system covering the entire foundation pit 30 .

[0080] Preferably, the spray device is a fog cannon.

[0081] In this embodiment, there are multiple groups of skylight devices; the multiple groups of skylight devices are arranged in parallel, and the multiple groups of skylight devices are arranged independently, so as to realize the skylight control above the corresponding area of ​​the foundation pit 30, which is highly flexible and easy to disassemble and replace.

[0082] The corresponding dust-proof net components are designed to be curtain-style. Once the corresponding dust-proof net components are damaged, the operator can stand at one end and gather them all at one end like pulling a curtain, and remove them to facilitate the replacement and repair of the dust-proof net.

[0083] In a preferred embodiment of the present application, the longitudinal center axis of the first dustproof net assembly 320 is arranged to be consistent with the longitudinal center axis of the second dustproof net assembly 420, so as to improve the accuracy of the two-way independent opening control, improve the extension and docking coverage of the relatively arranged first and second curtain mechanisms 300 and 400, and prevent misalignment from causing coverage deficiencies.

[0084] In a preferred embodiment of the present application, the transmission wire rope mechanism 500 includes two steel ropes, which are symmetrically arranged relative to the longitudinal center axis of the first dustproof net assembly 320, thereby improving the uniformity of the load on the first dustproof net assembly 320 and the second dustproof net assembly 420 and ensuring effective coverage area.

[0085] Specifically, the two steel ropes are connected to the first dustproof net assembly 320 and the second dustproof net assembly 420 by hanging wheels, and the two steel ropes are arranged close to both sides of the first dustproof net assembly 320 and the second dustproof net assembly 420 to prevent the corresponding dustproof net assemblies from opening and closing unevenly.

[0086] Furthermore, the system also includes a mobile terminal and a PC terminal connected to the main control center. Through the settings of the mobile terminal, operators can remotely control it through their mobile phones; specifically, click to start, and the corresponding dust screen component will slowly unfold; click to pause, and the corresponding dust screen component will immediately stop unfolding.

They are durable and flame-retardant. They can be recycled after the project is completed. After demolition, no construction waste is generated. They are low-carbon and environmentally friendly, reducing the pollution problem of conventional dust nets.

[0089] The implementation principle of a dustproof canopy system for foundation pits in the embodiment of the present application is as follows: during operation, the main control center controls the first canopy mechanism 300 and the second canopy mechanism 400 to move relative to each other, extend and dock based on the abnormal air information obtained by the environmental detection device to form a shielding curtain net; or controls the first canopy mechanism 300 and the second canopy mechanism 400 to move back to back and close based on the abnormal weather information obtained in the cloud. For example, when the strong wind is greater than level 5 or it rains heavily or snows, it will increase the dynamic load of the overall system and pose a safety hazard, so it will automatically retract at this time. The scheme disclosed in the present application can realize the two-way independent opening and closing control of the dustproof net above the foundation pit 30, with a fast covering rate and good dust shielding effect, effectively solving the problems of dust and nuisance caused by earthwork construction, beautifying the site environment, and realizing green construction; at the same time, it also greatly reduces the number of days of shutdown due to extreme weather such as haze and strong wind, increases the effective construction time, and shortens the delivery cycle.

[0090] Specifically, under conditions of severe air pollution due to haze or extremely severe pollution weather, the system disclosed in the present application can form an independent construction space in the foundation pit 30. The water spraying devices and spraying devices arranged on the surrounding sides can greatly improve the air quality in the foundation pit 30 covered by the system, comprehensively reduce the emission of floating dust from earth excavation at the construction site, further alleviate dust pollution, and effectively solve the problem that all work must be stopped due to severe air pollution due to "haze" or extremely severe pollution weather.

[0091] In hot weather, this application can effectively weaken solar radiation, reduce the adverse effects of high temperature on construction, create a good construction environment for workers participating in the 30th phase of foundation pit construction, and bring "coolness" to workers working outdoors in hot weather, which will promote shortening construction period and construction safety in hot seasons.

[0092] During night construction, the lighting during construction and the arc light generated by electric welding are blocked by the curtain net formed by the system. Only a soft halo can be shown outside, which will not directly shine on residential buildings, effectively alleviating the problem of light pollution. At the same time, the coverage of the curtain net can effectively reduce the noise from the construction of foundation pit 30. According to testing, the noise outside the system can be controlled below 55dB during night construction, meeting the requirements of GB12523-2011 "Environmental Noise Emission Standards for Construction Sites".

[0093] Furthermore, the system also includes a top spray device, which includes a suspended bearing assembly and a suspended spray assembly. The suspended bearing assembly is arranged at the bottom of the first dustproof net assembly 320 and the second dustproof net assembly 420; the suspended spray assembly is installed on the suspended bearing assembly.

[0094] There are multiple suspended bearing components; each suspended bearing component is provided with multiple suspended spray components; multiple suspended bearing components form a spray network covering the foundation pit. Through the setting of the top spray device and the surrounding water spray device and the spray device, a three-dimensional spray system covering the foundation pit is formed, which effectively reduces dust emissions and realizes green and environmentally friendly construction operations.

[0095] Preferably, the suspended load-bearing assembly comprises a steel wire rope.

[0096] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
