Description

Technical Field

[0001] The utility model relates to a tunnel drainage system, in particular to a tunnel drainage dredging device. Background Art

[0002] Tunnel engineering occupies an important position in modern transportation infrastructure, and with the increase in tunnel length and complexity, the design and management of drainage systems have become particularly critical. The reliability of the drainage system directly determines the operational safety of the tunnel project. Generally speaking, the tunnel drainage system is mainly composed of circumferential drainage pipes, longitudinal drainage pipes, transverse drainage pipes, and central drainage ditches behind the secondary lining. The accumulated water behind the secondary lining is drained to the central drainage ditch through the circumferential drainage pipes, longitudinal drainage pipes, and transverse drainage pipes, so as to reduce the water pressure behind the secondary lining and improve the durability of the lining structure. There are two main types of blockages in tunnel drainage systems: one is caused by sediment; the other is caused by chemical crystallization. In the groundwater behind the secondary lining of tunnels in karst areas, there is a lot of sediment. as well as The content is high, while the primary support shotcrete of the tunnel contains a lot of Ca 2+ When groundwater passes through the primary branch, it forms a large number of carbonate crystals, leading to crystal blockage in the tunnel drainage system. Crystal blockage is one of the most common problems in tunnels located in karst areas. This often causes cracking in the tunnel lining, water leakage, pavement bulging, and flooding, seriously impacting tunnel safety. Furthermore, because tunnel drainage systems are typically concealed, the transverse drain pipes behind the secondary lining are particularly prone to blockage due to their shallow longitudinal slope, making them extremely difficult to clean and maintain on a daily basis. If appropriate measures are not taken to clean transverse drain pipes in tunnels with recrystallization zones, their normal service life is extremely short. The tunnel typically operates for 3-5 years before the drainage system behind the secondary lining becomes essentially ineffective. To address this problem, a type of equipment has emerged. Its structure generally consists of a drill bit at the front and a running mechanism at the back. However, the drill bit diameter is much smaller than the transverse drain pipe diameter, which can easily cause the equipment to become stuck in the crystals. Furthermore, such equipment cannot completely remove the crystals within the transverse drain pipes. Utility Model Content

[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention and are not intended to limit the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1-4 As shown, a tunnel drainage dredging device includes a fixed block 1, which is a rectangular parallelepiped. A rotating motor 6 is fixed to the rear end of the fixed block 1 by bolts. The rotating motor 6 is coaxial with the fixed block 1. A through hole is provided on the fixed block 1 corresponding to the output shaft of the rotating motor 6. The output shaft of the rotating motor 6 is connected to the rotating shaft 7 in the through hole. An electric telescopic rod 2 is vertically arranged in the middle of each side of the fixed block 1. The execution end of the electric telescopic rod 2 is provided with a moving wheel. The moving wheel includes a U-shaped mounting frame 3. A shaft is rotatably provided between the two sides of the U-shaped mounting frame 3. A roller 4 is fixed on the shaft. A drive motor 5 is fixed to the mounting frame 3 by bolts. The output shaft of the drive motor 5 is connected to the shaft. The free end of the rotating shaft 7 is connected to a cone 8 with the tip facing forward. A plurality of stirring members are evenly spaced along the length direction of the rotating shaft 7. The stirring members include a mounting ring, which is fixed to the rotating shaft 7 by screws 12. A plurality of outer tubes 9 are evenly spaced circumferentially provided on the mounting ring. A movable rod 10 is slidably provided in the outer tube 9. One end of the movable rod 10 is exposed to the outer tube 9. A through hole is vertically provided on the outer tube 9. A tightening screw 11 is provided in the through hole for tightening the movable rod 10, so that the length of the stirring rod formed by the outer tube 9 and the movable rod 10 is adjustable. The lengths of the stirring rods of the plurality of stirring members increase successively from front to back. The free end of the stirring rod of the frontmost stirring member protrudes from the large end of the cone 8. The free end of the stirring rod of the rearmost stirring member is flush with the side of the moving wheel away from the electric telescopic rod 2. The free end of the stirring rod of the rearmost stirring member is vertically connected to a cleaning rod 13 extending forward. The device is powered by AC power, that is, the device is connected to AC power through a power cord, and the power cord supplies power to the rotating motor 6, each drive motor 5 and the electric telescopic rod 2.

[0028] When the device is used, first, start the electric telescopic rod 2 and adjust the length of the electric telescopic rod 2 according to the size of the transverse drain pipe, loosen the tightening screw 11 to adjust the length of the stirring rod, and lock the tightening screw 11 after adjustment, so that the cone 8 faces forward and the device is placed in the transverse drain pipe from one end of the transverse drain pipe. Each moving wheel contacts the inner wall of the transverse drain pipe, and the rotating motor 6 is started. The rotating motor 6 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the cone 8 and the stirring rod thereon to rotate to break the crystals on the wall of the transverse drain pipe. When the rotating motor 6 is started, each driving motor 5 is started at the same time. The driving motor 5 drives the shaft to rotate, so that the roller 4 on the shaft rolls on the inner wall of the transverse drain pipe. The rolling of the roller 4 moves the device forward, and finally realizes that the device moves forward in the transverse drain pipe while breaking the crystals in the transverse drain pipe until it reaches the other end of the transverse drain pipe. At this time, the power cord is removed from the mains and the device is taken out from the transverse drain pipe.

[0029] The device's cone 8 and the agitating rods of the multiple agitating elements form a large, tapered drill bit. The large end of the drill bit rests against the inner wall of the horizontal drain pipe, effectively breaking up crystals within the pipe without causing any jamming. The provision of a cleaning rod 13 ensures the device is fully capable of breaking up crystals within the pipe. The provision of an electrically operated telescopic rod 2 and the adjustable length of the agitating rod allow the device to accommodate pipes of varying diameters.

[0030] Example 2

[0031] like Figure 1-4 As shown, the difference from Example 1 is that the fixed block 1 is a hollow structure, and a battery and a controller are provided in the fixed block 1. The battery supplies power to the device. The device is connected to a pull rope through a tension sensor, and the other end of the pull rope is connected and wound around a winding reel. The length of the pull rope is just enough to enable the device to reach the other end of the transverse drainage pipe from one end of the transverse drainage pipe. The tension sensor is connected to the controller, and the controller is connected to the drive circuit of the rotating motor 6 and the drive circuit of each drive motor 5. Each drive motor 5 is a forward and reverse motor.

[0032] The device will pull the pull rope when moving in the horizontal drain pipe and breaking crystals. After the pull rope is unloaded from the winding drum, when the tension detected by the tension sensor reaches the set value, the controller controls the rotating motor 6 to stop, controls each driving motor 5 to reverse, and slowly winds the pull rope around the winding drum, so that only one end of the horizontal drain pipe needs to be opened without opening the other end.

[0033] Example 3

[0034] like Figure 1-4As shown, the difference from the first embodiment is that a fixed cylinder 14 is fixedly provided on the front side of the fixed block 1, and the fixed cylinder 14 is coaxially sleeved on the outside of the rotating shaft 7. A first annular cavity is provided in the wall of the fixed cylinder 14, and the first annular cavity is coaxial with the rotating shaft 7. A ring-shaped communicating port is provided on the front side of the fixed cylinder 14, and the annular communicating port is connected to the first annular cavity. A ring-shaped connecting port is provided on the front side of the fixed cylinder 14, and the connecting port is T-shaped in the longitudinal cross-section in the front-to-back direction. The first annular cavity is connected to the water source through a pipeline and a pump. A rotating cylinder 15 is provided on the front side of the fixed cylinder 14, and the rotating cylinder 15 is coaxially fixedly sleeved on the outside of the rotating shaft 7. A second annular cavity is provided in the wall of the rotating cylinder 15, and the second annular cavity is coaxial with the rotating shaft 7. An annular connector is provided on the rear side of the rotating cylinder 7 to connect The head is T-shaped in the longitudinal cross-section in the front-to-back direction, the annular connecting head corresponds to and fits with the annular connecting port, the annular connecting head can be rotatably located in the annular connecting port, the rotating cylinder 15 is provided with a connecting port corresponding to the connecting port of the fixed cylinder 14, the connecting port of the rotating cylinder is connected to the second annular cavity, the second annular cavity is provided with a plurality of water holes evenly spaced along its circumference facing the side of the rotating shaft 7, the rotating shaft 7 is a hollow structure, the rotating shaft 7 in the rotating cylinder 15 is provided with a water inlet 16 corresponding to each water hole, and the rotating shaft 7 in front of the rotating cylinder 15 is provided with a plurality of water outlets 17, and the plurality of water outlets 17 are respectively arranged between adjacent stirring members and between the stirring members and the cone, each group of water outlets 17 includes a plurality of water outlets, and the plurality of water outlets are evenly spaced along the circumference of the rotating shaft.

[0035] A connecting rod 18 is vertically connected to the lower side of the fixed cylinder 14. The connecting rod 18 is connected to the fixed cylinder 14 by bolts. The free end of the connecting rod 18 is connected to a vertical cleaning plate 19. The lower side of the cleaning plate 19 is an outward-protruding arc. The cleaning plate 19 is crescent-shaped as a whole, and the front of the lower side of the cleaning plate 19 is beveled. For horizontal drainage pipes of different diameters, the fixed cylinders are connected with connecting rods 18 of different lengths and cleaning plates 19 of different sizes.

[0036] The arrangement of fixed drum 14, rotating drum 15, and hollow shaft 7 enables the device to spray water onto the inner wall of the transverse drain pipe, moistening the crystals and enabling smoother crystal removal. The presence of cleaning plate 19 prevents large amounts of crystals from falling and accumulating at the bottom of the transverse drain pipe. The beveled shape of the cleaning plate on its lower front side facilitates cleaning and provides a more consistent fit.
