Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a reverse slope drainage device for tunnel construction. Background Technology

[0002] Tunnel drainage is one of the important procedures in tunnel construction. During tunnel construction, in addition to construction water, we often encounter fissure water, rainwater, and pipe water. During tunnel construction, drainage devices are often required to drain water from the tunnel. Especially when tunnels are constructed on reverse slopes, the tunnel entrance is usually higher than the ground level inside the tunnel due to the tunnel's inclination. In this case, drainage is more difficult than in normal tunnel construction. Furthermore, because the water contains mud and sand, large amounts of mud and sand often adhere to the drainage pipes, thus hindering drainage work and reducing drainage efficiency.

[0003] In the prior art, such as the reverse slope tunnel construction drainage device disclosed in CN213205754U, there is a reverse slope tunnel drainer, which includes a water pump. The water pump has a connection port on its right side, and the inner wall of the connection port is threaded. The connection port is connected to a drain pipe through the thread. The left end of the outer side of the drain pipe has a threaded rod. The device cleans the soil and gravel located on the left end of the inner wall of the circular perforation through a circular block and a wedge-shaped groove. When the left side of the circular block comes into contact with the soil and gravel, the surface soil is cleaned through the wedge-shaped groove, causing it to move along the track of the wedge-shaped groove and adhere to the inner wall of the wedge-shaped groove. At this time, the spring block is in a stretched state. In this way, the soil on the inner wall of the drain pipe is cleaned. However, when using this device, it is necessary to disassemble the device and then clean the inner wall of the drain pipe, which makes it difficult to clean the inner wall quickly during the entire drainage process.

[0004] Therefore, there is an urgent need for a drainage device that solves the problem that when cleaning the inner wall of a drainage device, it is necessary to disassemble the device first, and after cleaning, it is necessary to spend a lot of time reinstalling it, resulting in a slow overall drainage efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a reverse slope drainage device for tunnel construction to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A tunnel construction reverse slope drainage device includes a connecting pipe, one end of which is connected to a water pump, and a filter element with a diameter adapted to the inner diameter of the connecting pipe; a drainage pipe, one end of which is detachably connected to the other end of the connecting pipe; two pulley components, each located on the end face of the drainage pipe away from the connecting pipe, and arranged symmetrically; a mounting platform, located on the outer wall of the drainage pipe, with two winding components at one end, each located vertically above the two pulley components, the winding components being wound with connecting ropes, and the connecting ropes of the two winding components entering the two pulley components vertically and then horizontally into the drainage pipe; and a cleaning ring, detachably installed inside the drainage pipe, with a diameter adapted to the inner diameter of the drainage pipe. When the cleaning ring is installed in the drainage pipe, one end of each of the two connecting ropes entering the drainage pipe is detachably connected to the cleaning ring, and the connecting ropes entering the drainage pipe are parallel to the axial direction of the drainage pipe, the two connecting ropes driving the cleaning ring to move axially along the drainage pipe.

[0010] In some embodiments, the axis of the rope groove, the arc end, and the drain pipe are located in the same plane, and the groove between the two ends of the rope groove faces the axis of the drain pipe.

[0011] In some embodiments, the arc-shaped inner wall surface of the limiting slide is provided with a column adapted to the rope groove, and the column extends along the axial direction of the drain pipe.

When the cleaning ring is installed on the drain pipe, the limiting boss is inserted into the limiting slide, and the column is inserted into the rope groove. One end of the connecting rope provided in the rope groove is detachably connected to the end face of the column.

[0012] In some embodiments, the pulley component includes a connecting plate and a pulley. The connecting plate has an L-shaped structure and includes a horizontal plate and a vertical plate that are perpendicular to each other. The end face of the vertical plate is fixedly connected to the end face of the drain pipe. The side face of the horizontal plate is parallel to the end face of the drain pipe. The pulley is disposed between the end face of the drain pipe and the side face of the horizontal plate. The side face of the horizontal plate is provided with two opposing support plates. The pulley is disposed between the two support plates and is rotatably connected to the two support plates. The connecting rope enters the pulley in the vertical direction and leaves the pulley in the horizontal direction.

[0013] In some embodiments, the connecting rope disposed in the rope groove extends axially along the drain pipe to the bottom of the pulley and winds around a quarter circumference toward the outer wall to one side of the pulley.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0050] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0051] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0052] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0053] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0055] It should be understood that during the construction of reverse slope tunnels, the presence of sand and soil leads to a large amount of soil and sand adhering to the inner wall of the drainage pipe, affecting drainage efficiency. Furthermore, in existing technologies, the drainage device needs to be disassembled when cleaning the soil and sand, and then reinstalled after cleaning, which takes a lot of time.

[0056] To improve the above problems, this embodiment provides a tunnel construction reverse slope drainage device, which mainly includes a connecting pipe 1, a drainage pipe 2, two pulley components 3, a mounting platform 4, and a cleaning ring 7.

[0057] In this embodiment, as Figures 1-2 As shown, the connecting pipe 1 has a cylindrical structure and an external thread at one end for connecting to the water pump. The connecting pipe 1 contains a filter element 11 with a diameter that matches the inner diameter of the connecting pipe 1, thereby filtering out some of the sediment in the water. The other end is connected to the drain pipe 2 for drainage.

[0058] The filter element 11 can be a filter screen or other filter device.

[0059] In this embodiment, as Figures 1-2 As shown, the drain pipe 2 has a cylindrical structure, and one end is detachably connected to the other end of the connecting pipe 1. Specifically, four fixing blocks 9 are provided on the circumferential outer wall of one end of the drain pipe 2. The four fixing blocks 9 are arranged alternately along the circumferential outer wall of the drain pipe 2 and are evenly distributed at the four ends of the circumferential outer wall of the drain pipe 2. Four fixing blocks 9 are also provided on the circumferential outer wall of one end of the connecting pipe 1. The four fixing blocks 9 are arranged alternately along the circumferential outer wall of the connecting pipe 1 and are evenly distributed at the four ends of the circumferential outer wall of the connecting pipe 1. The four fixing blocks 9 of the connecting pipe 1 and the fixing pipe correspond one-to-one, and one side of each of the four fixing blocks 9 of the connecting pipe 1 is... The end face of the connecting pipe 1 facing the drain pipe 2 is on the same plane as the end face of the drain pipe 2 facing the connecting pipe 1. One side of each of the four fixing blocks 9 of the drain pipe 2 is on the same plane as the end face of the drain pipe 2 facing the connecting pipe 1. When the connecting pipe 1 is connected to the drain pipe 2, the sides of the four fixing blocks 9 of the drain pipe 2 abut and fit against the sides of the four fixing blocks 9 of the connecting pipe 1. Each of the eight fixing blocks 9 is provided with a fixing hole 91. When two fixing blocks 9 abut against each other, the fixing holes 91 of the two fixing blocks 9 are opposite and connected. Then, the bolts can be bolted together by passing the bolts 10 through the two fixing holes 91, making the connection between the connecting pipe 1 and the drain pipe 2 simple and stable.

[0060] The joint between the connecting pipe 1 and the drain pipe 2 can be sealed with a sealing gasket, which is existing technology and will not be elaborated further.

[0061] In this embodiment, as Figures 6-11As shown, the cleaning ring 7 adopts a cylindrical structure, and its diameter is adapted to the inner diameter of the drain pipe 2. The cleaning ring 7 is detachably installed inside the drain pipe 2, and the axis of the cleaning ring 7 coincides with that of the drain pipe 2. Specifically, the outer circumferential wall of the cleaning ring 7 is provided with four limiting grooves 71. The four limiting grooves 71 are opened along the axial direction of the cleaning ring 7, and the four limiting grooves 71 are arranged sequentially at intervals along the circumference of the cleaning ring 7. The angle between any two adjacent limiting grooves 71 is the same. The end slots are respectively set on the same plane as the end faces of the two ends of the cleaning ring 7. The inner wall of the drain pipe 2 is provided with four limiting protrusions 21. The extension direction of the four limiting protrusions 21 is consistent with the axial direction of the drain pipe 2, and they are respectively adapted to the four limiting grooves 71. The four limiting protrusions 21 pass through the four limiting grooves 71, so that the cleaning ring 7 can be displaced along the axial direction of the drain pipe 2 and the direction is stable. Then, the mud and sand on the inner wall of the drain pipe 2 are scraped out by the cleaning ring 7, thereby cleaning the inner wall of the drain pipe 2.

[0062] In this embodiment, for ease of description, the drain pipe 2 is placed horizontally on the ground, and one of the limiting protrusions 21 on the inner wall of the drain pipe 2 is located at the top of the inner wall of the drain pipe 2. In this embodiment, as shown... Figures 1-5 As shown, two pulley components 3 are provided on the end face of the drain pipe 2 away from the connecting pipe 1. The two pulley components 3 are arranged opposite each other at both ends of the end face of the drain pipe 2. Specifically, the pulley component 3 includes a connecting plate 31 and a pulley 32. The connecting plate 31 adopts an L-shaped structure and includes a horizontal plate 311 and a vertical plate 312 that are perpendicular to each other. The end face of the vertical plate 312 is fixedly connected to the end face of the drain pipe 2, thereby forming an L-shaped structure. The side of the horizontal plate 311 is parallel to the end face of the drain pipe 2, and the pulley 32 is arranged at the end of the drain pipe 2. Between the side of the horizontal plate 311 and the side of the horizontal plate 311, there are two opposing support plates 313 on the side of the horizontal plate 311 facing the drain pipe 2. The two support plates 313 have a rectangular structure, with one end facing the drain pipe 2 and the other end set on the horizontal plate 311. The upper and lower sides of the two support plates 313 are parallel to the horizontal ground. The pulley 32 is set between the two support plates 313 and is rotatably connected to the opposite side of the two support plates 313. The axis of the pulley 32 is perpendicular to the opposite side of the two support plates 313.

[0063] Among them, such as Figures 1-4As shown, the mounting platform 4 is set on the outer wall of the drain pipe 2, and one end is provided with two winding parts 5. The two winding parts 5 are respectively set on the vertical upper side of the two pulley parts 3. The winding parts 5 are wound with connecting ropes 6. After the connecting ropes 6 of the two winding parts 5 enter the two pulley parts 3 vertically, they leave the pulley 32 horizontally and enter the drain pipe 2. One end of the two connecting ropes 6 entering the drain pipe 2 is detachably connected to the cleaning ring 7. The connecting ropes 6 entering the drain pipe 2 are parallel to the axis of the drain pipe 2. The two connecting ropes 6 drive the cleaning ring 7 to move along the axis of the drain pipe 2, so that the cleaning ring 7 cleans the inner wall of the drain pipe 2.

[0064] In this embodiment, as Figure 1 , Figure 3 , Figure 8 and Figure 10 As shown, the limiting boss 21 has an arc end 22 facing the axis of the drain pipe 2. The cross section of the arc end 22 adopts a hemispherical structure. The arc end 22 has a rope groove 221 along the axis of the drain pipe 2. The rope groove 221 is adapted to the connecting rope 6, and the connecting rope 6 that passes through the drain pipe 2 is set in the rope groove 221, thereby making the position of the connecting rope 6 stable and not easily impacted by the drainage.

[0065] Among them, the grooves at both ends of the rope groove 221 are respectively set on the end faces of the limiting boss 21. The end face of one end of the limiting boss 21 and the end face of the drain pipe 2 away from the connecting pipe 1 are located on the same plane. The limiting slide 71 is adapted to the limiting boss 21, and the inner wall of the limiting slide 71 adopts an arc surface structure.

[0066] In this embodiment, the rope groove 221, the arc end 22 with the rope groove 221, and the axis of the drain pipe 2 are all located in the same plane. When the drain pipe 2 is placed on a horizontal ground, the plane containing the rope groove 221 and the arc end 22 with the rope groove 221 is parallel to the horizontal ground, and the groove opening between the two ends of the rope groove 221 faces the axis of the drain pipe 2. This makes the force on the cleaning ring 7 more uniform and stable, and thus makes the displacement of the cleaning ring 7 more stable.

[0067] In this embodiment, as Figures 6-11As shown, two of the four limiting grooves 71 have arc-shaped inner wall surfaces that are adapted to the rope groove 221. The column 72 extends along the axial direction of the drain pipe 2. The length of the column 72 is consistent with the axial length of the limiting groove 71 and the drain pipe 2. The outer wall of the column 72 facing the axis of the cleaning ring 7 coincides with the arc-shaped inner wall surface of the limiting groove 71. The shape and size of the coincidence are consistent with the shape and size of the groove between the two ends of the rope groove 221. When the cleaning ring 7 is installed on the drain pipe 2, the limiting boss 21 is inserted into the limiting groove 71, and the column 72 is inserted into the rope groove 221. One end of the connecting rope 6 in the rope groove 221 is detachably connected to the end face of the column 72. The end face of the column 72 connected to the connecting rope 6 is provided with a connecting ring 721. One end of the connecting rope 6 is detachably connected to the connecting ring 721.

[0068] One end of the connecting rope 6 is connected to the connecting ring 721 by binding.

[0069] In this embodiment, the connecting rope 6, located in the rope groove 221, extends axially along the drain pipe 2 to the bottom of the pulley 32 and wraps around the outer wall of the pulley 32 to the side away from the drain pipe 2. One end of the connecting rope 6 enters the winding member 5 on the upper side of the pulley 32 along the side of the pulley 32 away from the drain pipe 2. When the drain pipe 2 is placed on a horizontal surface, and the plane of the rope groove 221, the limiting boss 21, and the axis of the drain pipe 2 is parallel to the horizontal surface, the connecting rope 6 enters horizontally along the axis of the drain pipe 2 to the bottom of the pulley 32 and enters the winding member 5 in a direction perpendicular to the horizontal surface. The plane of the connecting rope 6 on the lower side of the pulley 32 and the connecting rope 6 on one side of the pulley 32 is perpendicular to the axis of the pulley 32 and parallel to the axis of the drain pipe 2. This allows the two connecting ropes 6 to be connected to the cleaning ring 7, which can pull the two ends of the cleaning ring 7, thereby driving the cleaning ring 7 to move stably along the axis of the drain pipe 2 and cleaning the drain pipe 2.

[0070] Among them, such as Figure 1 and Figure 12 As shown, the inner wall of the drain pipe 2 near the connecting pipe 1 is provided with multiple limiting blocks 23. The multiple limiting blocks 23 are arranged sequentially and spaced apart along the circumference of the inner wall of the drain pipe 2, and are attached to and abut against the side of the cleaning ring 7 facing the connecting pipe 1, thereby limiting the cleaning ring 7 and preventing the cleaning ring 7 from exceeding the preset position during installation. At the same time, when the cleaning ring 7 is moved to the end of the drain pipe 2 near the pulley 32 to complete cleaning, the cleaning ring 7 is moved along the limiting boss 21 to the limiting block 23, thereby limiting the displacement of the cleaning ring 7.

[0071] Among them, such as Figure 4 , Figure 6 , Figure 11 and Figure 13As shown, the device also includes four plug-in rods 20, one end of which is provided with an external thread. The outer wall of the cleaning ring 7 is provided with four stabilizing holes 73 that are adapted to the plug-in rods 20. The outer wall of the drain pipe 2 is provided with four plug-in holes 24 that are adapted to the plug-in rods 20. The four plug-in holes 24 are respectively located between the four connecting blocks, and the spacing between two adjacent plug-in holes 24 is consistent. When the cleaning ring 7 is installed in the drain pipe 2, the side of the cleaning ring 7 abuts against the side of multiple limiting blocks 23. The four stabilizing holes 73 are connected to the four plug-in holes 24. After the four plug-in rods 20 are inserted into the four plug-in holes 24 respectively, they are then inserted into the four stabilizing holes 73 and abut against the bottom inner wall of the stabilizing holes 73. One end of the plug-in rod 20 is connected to a nut, thereby making the cleaning ring 7 stably installed in the drain pipe 2. The disassembly and installation are relatively simple.

[0072] In this embodiment, as Figures 1-4 As shown, the lower surface of the mounting platform 4 is provided with a groove 41 adapted to the drain pipe 2. The plane containing the connecting rope 6 on the lower side of the pulley 32 and the connecting rope 6 on one side of it is perpendicular to the upper surface of the mounting platform 4. When the drain pipe 2 is placed on the horizontal ground in the above position, the upper surface of the mounting platform 4 is parallel to the horizontal ground. One end of the mounting platform 4 extends along the axial direction of the drain pipe 2 and is located on the vertical upper side of the pulley 32. Two cable winding parts 5 are respectively set on the end face of the mounting platform 4 away from the connecting pipe 1 and are respectively set on the upper side of the two pulleys 32. Specifically, the end face of the mounting platform 4 located on the upper side of the pulley 32 is provided with two cable winding grooves 42, and the two cable winding grooves 42 are opposite to each other. The mounting platform 4 is equipped with two slots located vertically above the two pulleys 32. The cable winding slot 42 has two slots located on the upper surface of the mounting platform 4 and the end face of the mounting platform 4 located at one end of the pulley 32. The cable winding component 5 includes a drive motor 52 and two spools 51. The two spools 51 are respectively located in the two cable winding slots 42, and their two ends are perpendicular to the two groove walls opposite to the cable winding slots 42. The two connecting ropes 6 leave the two pulleys 32 and enter the two spools 51 in a direction perpendicular to the ground. The two drive motors 52 are respectively located on both sides of the mounting platform 4 and connected to the spools 51, thereby driving the spools 51 to rotate.

[0073] In this embodiment, a control component 8 is provided on the upper surface of the mounting platform 4. Both drive motors 52 are electrically or wirelessly connected to the winding component 5. The control component 8 controls the two drive motors 52 to start and stop simultaneously, thereby making the cleaning ring 7 subjected to uniform force and stable displacement. At the same time, the speed of the drive shaft 51 of the two drive motors 52 can be preset by the control component 8, thereby making the speed of the drive shaft 51 of the two drive motors 52 consistent.

[0074] The control method between the control component 8 and the drive motor 52 is an existing technology, such as PLC, CNC, and module control, which will not be elaborated further.

[0075] In this embodiment, as Figure 3 and Figure 13 As shown, the upper side wall of the drain pipe 2 has a bolt hole 25, and the mounting platform 4 has a through hole 43. When the mounting platform 4 is installed on the drain pipe 2, the bolt hole 25 is connected to the through hole 43, so that the drain pipe 2 and the mounting platform 4 can be bolted together through the bolt hole 25 and the through hole 43.

[0076] In this embodiment, as Figure 1 as well as Figures 13-15 As shown, the lower side of one end of the mounting platform 4 extends downward along the direction perpendicular to the upper surface of the mounting platform 4, thus forming a baffle 44. The baffle 44 adopts an arc surface structure, and multiple positioning posts 441 are provided on the side facing the drain pipe 2. The multiple positioning posts 441 are arranged sequentially and spaced apart along the curvature direction of the arc surface of the baffle 44. The end face of the drain pipe 2 is provided with multiple positioning holes 26, which are arranged sequentially and spaced apart along the curvature direction of the end face of the drain pipe 2. The multiple positioning posts 441 are respectively adapted to the multiple positioning holes 26.
