DETAILED DESCRIPTION OF THE INVENTION

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Referring to Figures 1-4 , a safety risk control device during the construction period of rail transit, including a foundation pit 1 and a subway pipeline 2 buried in the foundation pit 1. A base 3 is embedded at the bottom of the subway pipeline 2. A protective cavity 4 is provided inside the inner wall of the subway pipeline 2. A first annular plate 5 and a second annular plate 6 are provided inside the protective cavity 4. The first annular plate 5 is attached to the inner wall of the protective cavity 4 away from the subway pipeline 2, and the second annular plate 6 is attached to the inner wall of the protective cavity close to the subway pipeline 2. Installation cavities 7 are provided on the left and right sides of the base 3. The first annular plate 5 and the two installation cavities 7 are provided with the same diversion assembly. The second annular plate 6 and the two installation cavities 7 are provided with the same drying assembly. The second annular plate 6, the first annular plate 5, the protective cavity 4, and the subway pipeline 2 are provided with the same control mechanism.

[0025] Among them, the diversion assembly includes an annular diversion pipe 8 embedded in the first annular plate 5. A plurality of water seepage pipes 9 are communicated with the annular diversion pipe 8. The plurality of water seepage pipes 9 are arranged in an array centered on the center of the first annular plate 5. Water collecting dishes 10 are fixedly installed at the bottoms of the two installation cavities 7. The water collected in the water collecting dishes 10 can be used for fire protection purposes. The two water collecting dishes 10 are symmetrically arranged. The bottom of the annular diversion pipe 8 is communicated with two inclined pipes 11. The two inclined pipes 11 are symmetrically arranged. The two inclined pipes 11 are respectively inserted into the two corresponding water collecting dishes 10.

[0026] Among them, the drying component includes a drying chamber 12 provided inside the second annular plate 6. Two hoses 13 are connected to the bottom of the drying chamber 12. The two hoses 13 are symmetrically arranged. Bearing plates 14 are fixedly installed in both installation cavities 7. Drying boxes 15 are fixedly installed on both bearing plates 14. Drying soil is filled in the drying boxes 15. The two hoses 13 are respectively inserted into the corresponding drying boxes 15. A plurality of cotton cores 16 are fixedly installed in the nozzles of the hoses 13 located inside the drying boxes 15. The setting of the cotton cores 16 involves the principle of osmosis. Since the drying soil is placed in the drying boxes 15, the inside of the drying boxes 15 is in a dry state. The cotton cores 16 can absorb the water seeping into the drying chamber 12. When the seeping water reaches the absorption load of the cotton cores 16, the water gradually detaches from the cotton cores 16 and enters the drying boxes 15.

[0027] More specifically, the control mechanism includes an annular water stop strip 17 and an annular airbag 18 arranged in the space of the protective cavity 4 between the second annular plate 6 and the first annular plate 5. The annular airbag 18 is filled with a gas that is brightly colored, non-toxic and harmless, and is easily detectable when discharged into the air. The annular water stop strip 17 is arranged in contact with the first annular plate 5, and the annular airbag 18 is arranged in contact with the second annular plate 6. A safety pipe 19 is connected to the annular airbag 18. A control valve is fixedly installed at the air outlet end of the safety pipe 19. A glass plate 20 and a rubber plate 21 are fixedly installed on the top surface of the inner side wall of the subway pipe 2. Two symmetrically arranged sliding rods 22 are fixedly installed on the side of the annular water stop strip 17 close to the annular airbag 18. Both sliding rods 22 slide through the protective cavity 4 and the top surface of the inner side wall of the subway pipe 2 and extend into the subway pipe 2. A silk sheet 23 is attached to the surface of the left sliding rod 22, and a fur sheet 24 is attached to the surface of the right sliding rod 22. The silk sheet 23 is arranged in contact with the glass plate 20. When the silk sheet 23 rubs against the glass plate 20, positive charges will be generated. At this time, negative charges will appear on the induction plate 26 in contact with the glass plate 20 due to charge induction. The fur sheet 24 is arranged in contact with the rubber plate 21. When the fur sheet 24 rubs against the rubber plate 21, negative charges will be generated. At this time, negative charges will appear on the induction plate 26 in contact with the rubber plate 21 due to charge induction. The glass plate 20 and the rubber plate 21 are fixedly installed with the same air collecting hood 25. Induction plates 26 are installed on the inner walls on the left and right sides of the air collecting hood 25. It should be noted that the two induction plates 26 are respectively arranged in contact with the glass plate 20 and the rubber plate 21. Then, according to the principle of charge induction, negative charges will be generated on the left induction plate 26, and positive charges will be generated on the right induction plate 26. Conductive needles 27 are fixedly installed on the opposite sides of the two induction plates 26. The opposite sides of the two conductive needles 27 have sharp tips. The charges accumulated on the induction plates 26 are finally transmitted to the tips of the conductive needles 27. When the charges at the tips of the two conductive needles 27 accumulate to a certain extent, a corona discharge phenomenon can occur, producing a flash effect. The air collecting hood 25 is filled with rare gases.

[0028] In the present invention, when water seepage occurs in the foundation pit 1 belonging to the subway pipeline 2, when water seeps into the protection cavity 4 from the outer side wall of the subway pipeline 2, first, the water penetrates into the first annular plate 5, and a plurality of water seepage pipes 9 in the first annular plate 5 divert the water into the annular diversion pipe 8, and then flow to the water collecting dish 10 in the installation cavity 7 of the base 3, thus completing the recovery of water. The recovered water can be pumped away by external equipment and used for fire extinguishing purposes, thus completing the preliminary treatment of the seepage water. When the seepage water enters between the first annular plate 5 and the second annular plate 6 in the protection cavity 4, the seepage water reacts with the annular water stop strip 17, so that the water is absorbed by the annular water stop strip 17, and the annular water stop strip 17 itself will also expand, thus completing the absorption treatment of the seepage water. When the seepage water penetrates into the second annular plate 6, at this time, most of the seepage water has decreased compared with when it just entered the outer wall of the subway pipeline 2. The seepage water penetrates into the drying cavity 12 in the second annular plate 6. At this time, due to the gravity of the water, the seepage water flows into the hose 13. When the plurality of cotton cores 16 in the hose 13 reach the saturated state of absorption, due to the seepage principle, the dry environment of the dry soil in the drying box 15 causes the water absorbed in the cotton cores 16 to gradually separate, thus completing the drying treatment of the water seeping into the second annular plate 6, thereby preventing the water from seeping into the subway pipeline 2 and affecting the construction safety. Since the annular water stop strip 17 expands, it will squeeze the annular airbag 18, so that the non-toxic, harmless and brightly colored gas inside it is discharged through the safety pipe 19, emitting a warning signal to remind the constructors in the pipeline that there is water seepage, so as to do a good job in prevention. Moreover, the expansion of the annular water stop strip 17 causes the two slide bars 22 to move downward synchronously. Due to triboelectrification, when the left slide bar 22 moves downward, the silk piece 23 on the surface of the left slide bar 22 rubs against the left glass plate 20, thus generating positive charges. When the right slide bar 22 moves downward, the fur piece 24 on the surface of the right slide bar 22 rubs against the rubber plate 21, generating negative charges. Since the glass plate 20 and the rubber plate 21 are in contact, according to the charge induction principle, negative charges will be generated on the left induction plate 26 and positive charges will be generated on the right induction plate 26 on the inner walls of the left and right sides of the air collecting hood 25. A large amount of charges are accumulated on the conductive needles 27 on the left and right sides. When a certain degree is accumulated, tip discharge can occur at the tips on the opposite sides of the two conductive needles 27, thus breaking down the rare gas in the air collecting hood 25 and producing a flash effect, and reminding the constructors in the pipeline again, thus completing the safety risk control during the track construction process.

[0029] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
