[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example

[0018] Reference Figure 1 As shown, this utility model discloses an intelligent circulating water dust prevention and noise reduction water curtain system, including: a dewatering well 1, an intelligent controller 2, a multi-stage filter 3, a water curtain control system 4, and a terminal spraying device 5; the dewatering well 1, the multi-stage filter 3, and the water curtain control system 4 are connected in sequence; the dewatering well 1 collects groundwater in the foundation pit of the subway station and transports it to the multi-stage filter 3 for filtration and purification through a water supply pipeline; the water curtain control system 4 transports the filtered and purified groundwater to the terminal spraying device 5 for spraying; the water curtain control system 4 is connected to the intelligent controller 2.

[0019] In this embodiment, the water curtain system also includes a dust monitoring system 6; the dust monitoring system 6 is installed on the top of the first-floor support beam of the foundation pit; the dust monitoring system 6 is connected to the intelligent controller 2; during use, the dust monitoring system 6 monitors the real-time dust situation of the foundation pit and is linked with the intelligent controller 2. When the dust exceeds the standard, the intelligent controller 2 sends a signal to the water curtain control system 4 to start the water curtain control system 4. The water flows through the water supply pipe into the multi-stage filter 3, and the filtered water is transported to the end spraying device 5 through the water curtain control system 4 for spraying, forming a water mist that covers the foundation pit and suppresses dust by sinking due to its own weight.

[0020] In this embodiment, the end spraying device 5 includes an end water pipe and nozzles; the end water pipe is installed on the support beam of the foundation pit; multiple nozzles are evenly distributed on the end water pipe; through the end water pipe and nozzles, an all-round water curtain is achieved.

[0021] In this embodiment, two adjacent nozzles are spaced 2 meters apart.

[0022] In this embodiment, the water curtain control system 4 includes a pressure valve; during use, the water supply pressure is adjusted by the pressure valve, thereby adjusting the range of water mist sprayed by the nozzle, and thus achieving the coverage range of the water curtain effect.

[0023] In this embodiment, the nozzle's radiation range is 3-4m.

[0024] In this embodiment, a high-pressure copper nozzle is used.

[0025] In this embodiment, the end water pipe is made of high-pressure resistant stainless steel.

[0026] In some other embodiments, the intelligent controller 2 is controlled by a digital chip.

[0027] This invention utilizes groundwater collected from dewatering wells within the foundation pit to provide a fine water curtain in real time during the excavation process, achieving dust suppression and cooling effects. During the later main structure construction phase, it can increase the humidity within the foundation pit, which is beneficial for structural curing and promotes concrete strength formation. Compared to traditional dust suppression measures such as manual watering and fog cannons, this water curtain system has advantages such as low investment, low cost, low carbon footprint, zero noise, wide coverage, and high dust suppression efficiency. It also solves construction problems such as poor air circulation and high working surface temperature within the foundation pit.
