Description

Technical Field

[0001] This utility model relates to sewage treatment equipment, specifically a water treatment device for water gushing during tunnel construction. Background Technology

[0002] With the increasing prevalence of tunnel construction in cities, the geological conditions during tunnel construction are often unstable, sometimes consisting of mud, sometimes gravel, cinders, and various ores. As tunnels are constantly being built, waterways can only be extended and constructed as open ditches. Construction water, flowing out along these ditches, occasionally carries branches, shrubs, and various types of waste from production and daily life. This severely impacts the normal operation of wastewater sedimentation reactors, sometimes even clogging the entire dosing area with mud, gravel, and debris, which then spreads to the sedimentation area. The mixer and scraper trip due to excessive resistance, causing the entire treatment system to shut down. Wastewater overflows from the ditches, polluting nearby farmland, orchards, and water sources. Furthermore, the treatment systems for tunnel construction water are all temporary facilities. Currently, sedimentation reactors are generally used to treat tunnel construction water. While these reactors are very effective initially, sudden geological changes and waste pollution can paralyze the system. When additional temporary land cannot be allocated, the sedimentation reactors must be modified to adapt to the changing conditions. Currently, there is no integrated, complete system for treating tunnel construction water. Therefore, it would be very beneficial to invent a water treatment device for water gushing during tunnel construction. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing sedimentation reactors for treating water inflow during tunnel construction by providing a water treatment device for water inflow during tunnel construction, thereby overcoming the deficiencies of existing wastewater treatment equipment.

The bar screen 1 has an inlet 4 on one side and a sludge outlet 5 at the bottom. The bar screen 1 is characterized by having a bar screen 6 inside. One side of the bar screen 1 is connected to the mixing chamber 2 through a first overflow plate 7. One side of the mixing chamber 2 is connected to the sludge remover 3 through a second overflow plate 9. A sand-water separator 10 is provided at the top of the mixing chamber 2, and the bottom of the sand-water separator 10 is connected to the mixing chamber 2.

[0005] A preferred technical solution of this utility model is as follows: The mixing chamber 2 is equipped with a frame mixer 8. The desliming device 3 is equipped with a scraper 11, and an inclined pipe 12 is arranged obliquely in the middle of the desliming device 3. A water collection tank 13 is provided at the upper part of the desliming device 3. A desliming outlet 14 is provided at the bottom of the desliming device 3, and a screw conveyor pump 15 is provided at the desliming outlet 14. The outlet of the screw conveyor pump 15 is connected to the inlet of the sand-water separator 10 through a circulation pipe 16.

[0006] This invention has the advantages of simple structure and small footprint, and it can efficiently handle water inrush during tunnel construction. Attached Figure Description
