Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a mobile spray dust suppression system for tunnel blasting construction. Background Technology

[0002] With the acceleration of urbanization and the continuous expansion of infrastructure construction, tunnel engineering plays a vital role in urban transportation and mountain road construction. However, during tunnel blasting construction, the explosion of explosives generates large amounts of dust and harmful gases. These substances not only pose a serious threat to the health of construction workers but may also pollute the surrounding environment, causing social and environmental problems.

[0003] In particular, during the period between tunnel blasting and muck removal, dust exhibits significant characteristics such as high concentration, wide particle size distribution, and localized accumulation. These characteristics necessitate that dust suppression measures be rapid, efficient, and targeted. However, existing dust suppression methods for tunnel blasting construction often suffer from limitations such as inconvenient equipment movement and poor adaptability, which restrict the environmental friendliness and construction efficiency of tunnel construction.

[0004] Furthermore, with increasingly stringent environmental regulations and heightened public awareness of health, stricter requirements have been placed on dust control during tunnel blasting operations. Therefore, developing a new type of dust suppression system for tunnel blasting is particularly urgent. This system should not only effectively reduce dust concentration but also possess good mobility and adaptability to meet the needs of different construction environments. Utility Model Content

[0013] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0014] See Figures 1-4 A mobile dust suppression spraying system for tunnel blasting includes a slide rail 6 fixed to the inner wall 1 of the tunnel, an arc-shaped spray pipe 4 slidably mounted on the slide rail 6, a water supply pipe 3 connected to the arc-shaped spray pipe 4, a water pump connected to the water supply pipe 3, and an integrated control system. An electric pulley 7 adapted to the slide rail 6 is installed on the arc-shaped spray pipe 4. The integrated control system is signal-connected to the electric pulley 7 and the water pump. Multiple water mist nozzles 5 are installed on the arc-shaped spray pipe 4. The end of the slide rail 6 should be close to the tunnel face 2 to enable immediate dust suppression after blasting.

[0015] Specifically, the water pump is a high-pressure pump, namely, a pump with ultra-high pressure (11 kg MAX), large flow rate (7 L / MIN), and high suction lift (1 meter). The high-pressure pump is responsible for drawing and pressurizing water from the water source to generate sufficient pressure to drive the sprinkler system. It can adjust the output water pressure according to the needs of the construction environment to adapt to the dust suppression requirements of different tunnel sections. The high-pressure pump ensures high-speed water flow. A water delivery hose connects the high-pressure pump and the sprinkler system, responsible for delivering the pressurized water to the nozzles. A slide rail 6 is installed inside the tunnel for easy movement. The dynamic sprinkler system provides guidance and support. Electric pulleys 7 are installed on the sprinkler system and work in conjunction with slide rails 6, allowing the sprinkler system to move smoothly on the slide rails 6. Arc-shaped sprinkler pipes 4 distribute water from the high-pressure water pump to various water mist nozzles 5. The water mist nozzles 5 atomize the water into fine droplets, which effectively combine with dust particles to achieve dust suppression. Multiple water mist nozzles 5 are evenly spaced on the arc-shaped sprinkler pipes 4, ensuring consistent dust suppression throughout the tunnel cross-section. The water mist nozzles 5 are adjustable in angle and particle size, with an adjustment range of 45° to 360° to adapt to different dust suppression needs. An integrated control system is used for remote control of the sprinkler system's start, stop, and movement. This system allows operators to remotely control the start and stop of the high-pressure water pump and the speed and direction of the sprinkler pipe movement, improving operational safety and convenience. This system is particularly suitable for the critical period after blasting and before slag removal in tunnel blasting construction, and can effectively deal with problems such as high dust concentration, wide particle size distribution and local accumulation.

[0016] The high-pressure water pump is the power source for the entire system, designed to operate at a pressure of 0.2-0.4 MPa. It is responsible for drawing and pressurizing water from the source to generate sufficient pressure to drive the spray system. The high-pressure water pump ensures that the water flows at high speed, thus forming a fine water mist upon spraying, which more effectively captures and settles dust. The formula for calculating the pump's operating pressure is as follows: In the formula, P Where is the spray working pressure, and Ke is the equivalent nozzle resistance coefficient. V Let g be the velocity of the liquid at the nozzle, and g be the acceleration due to gravity. ρ The density is the liquid density.

[0017] Preferred, such as Figure 2 and Figure 3 As shown, there are at least two slide rails 6, which are installed at intervals. There are also at least two electric pulleys 7, with each pair of electric pulleys 7 corresponding to one of the slide rails 6. The slide rails 6 can adapt to the construction needs of tunnels of different lengths. The electric pulleys 7 enable the smooth movement of the arc-shaped sprinkler pipe 4 on the slide rails 6, improving construction efficiency.

[0018] Preferred, such as Figure 4 As shown, a connecting rod 8 is fixed between the electric pulley 7 and the arc-shaped spray pipe 4. The slide rail 6 has a T-shaped groove along its length, and the electric pulley 7 is slidably installed in the groove. The connecting rod 8 extends out of the groove and is fixed to the arc-shaped spray pipe 4. The T-shaped groove restricts the sliding of the electric pulley 7 within the groove while connecting it to the arc-shaped spray pipe 4 via the extension rod. Specifically, the electric pulley 7 can be configured with two wheels rotatably connected to both ends of a rotating shaft, and the connecting rod 8 is connected to the rotating shaft, thereby achieving the installation of the connecting rod 8 and the electric pulley 7.

[0019] Preferably, there are two water supply pipes 3, which are respectively connected to the two ends of the arc-shaped spray pipe 4.

[0020] Preferably, the water pipe 3 is a flexible hose made of a synthetic material that is resistant to high pressure, wear, and chemicals, ensuring reliability under high pressure and harsh environments. The hose design gives the entire system a degree of flexibility, allowing it to adapt to different construction environments and locations.

[0021] This utility model relates to a mobile spray dust suppression system for tunnel blasting construction. Through the coordinated use of sliding rails and electric pulleys, it solves the technical problem of inconvenient equipment movement often found in existing dust suppression methods for tunnel blasting. The system's greatest advantage lies in its flexibility. Because of its mobile design, the system can be adjusted in position according to the on-site construction and dust distribution, improving dust suppression efficiency, protecting the health of construction workers, and achieving highly efficient and flexible dust suppression. Furthermore, the system's mobility and automated control further enhance construction efficiency and safety.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
