Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and more specifically, to a collection device for studying tunnel fissure water. Background Technology

[0002] Excessive accumulation of fissure water poses a significant safety hazard during tunnel construction, easily triggering severe geological disasters such as collapses and water inrushes. To effectively address this challenge, in-depth research into the characteristics of fissure water is crucial. Through precise analysis of fissure water, we can scientifically determine the optimal burial depth and reasonable orientation of the tunnel, while accurately predicting potential geological hazard risks, providing timely and reliable early warning information for construction units. Therefore, a special collection device for tunnel fissure water research has been designed to efficiently collect fissure water samples, facilitating subsequent in-depth research and treatment. This will help construction units take targeted measures, significantly reduce the incidence of construction accidents, and ensure the safe and smooth progress of tunnel engineering.

[0003] A search revealed Chinese patent application number 201920760161.9, which discloses a fissure water collection device. The device includes a closed collection tank, with a gooseneck hose connected to the upper part of the tank and communicating with its interior. The free end of the gooseneck hose has a fissure water collection nozzle. A drain pipe with a drain valve is located at the bottom of the collection tank. This invention is characterized by its ease of fixation, resistance to breakage, and prevention of contamination of the collected fissure water, making it suitable for research. Furthermore, it has a wide range of applications and is convenient to use.

[0004] The above patent still has the following shortcomings: (1) It is not convenient to fix the position. Due to the differences in the distribution, size, shape and other characteristics of cracks in different tunnels, and the fixed shape and size of some collection devices, there is a lack of sufficient adaptability. They cannot be adjusted and optimized according to specific circumstances, which leads to unstable fixed position.

[0005] (2) The pipe is prone to blockage. Since the tunnel fissure water usually carries a certain amount of mud and gravel, it is impossible to accurately collect data such as the water volume and water quality of the tunnel fissure water, which affects the comprehensive understanding and accurate analysis of the tunnel hydrogeological conditions.

[0006] Therefore, there is an urgent need for a collection device for tunnel fissure water research to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to address the current shortcomings of the inconvenience of fixing the position. Due to the differences in the distribution, size, and shape of cracks in different tunnels, and the fact that some collection devices have fixed shapes and sizes, they lack sufficient adaptability and cannot be adjusted and optimized according to specific circumstances, thus leading to the problem of unstable fixing position.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A collection device for tunnel fissure water research includes a collection tank and further includes:

[0010] A valve is installed at the bottom end of one side of the drain pipe, and a drain pipe is installed on one side of the valve;

[0011] The handle is rotatably connected to the top of both sides of the collection tank, and both sides of the collection tank are fixed with a mounting base.

[0012] A can lid is threaded onto the top of the collection tank, and a corrugated pipe is connected to the top of the can lid.

[0013] A filter structure is installed at the bottom of the bellows to filter the fissure water that enters the bellows.

[0014] A connecting pipe is installed at the bottom of the filter structure, and a plug is threaded to the bottom of the connecting pipe. A water inlet is opened inside the bottom of the plug, and a baffle is fixed to the outside of the bottom of the plug.

[0015] An expansion structure is provided on the outside of the connecting pipe. The expansion structure includes a connecting piece rotatably connected to the outside of the connecting pipe, a rubber sleeve sleeved on the outside of the connecting piece, and an adjustment component provided on the outside of the connecting pipe.

[0016] As a preferred technical solution of this application, the adjustment assembly includes a threaded tube connected to the outside of the connecting pipe, a push ring fixed to the bottom end of the threaded tube, and a retaining ring fixed to the outside of the rubber sleeve.

[0017] As a preferred technical solution of this application, the connecting pieces are arranged in several groups on the outside of the connecting tube, and the several groups of connecting pieces are distributed at equal intervals on the outside of the connecting tube.

[0018] As a preferred technical solution of this application, the frontal cross-section of the push ring has a funnel-shaped inclined structure, and the retaining rings are evenly distributed on the outside of the rubber sleeve.

[0019] As a preferred technical solution of this application, the filter structure includes a first rotating sleeve rotatably connected to the top of the connecting pipe, a cover fixed to the top of the first rotating sleeve, a filter screen fixed inside the cover, a second rotating sleeve fixed to the top of the cover and rotatably connected to the corrugated pipe, a drain outlet fixed to one side of the cover, and a debris shell threaded to the outside of the drain outlet.

[0031] 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, not all, of the embodiments of this utility model.

[0032] like Figure 1-5 As shown, the tunnel fracture water collection device proposed in this embodiment includes a collection tank 1, and further includes:

[0033] Valve 9 is installed at the bottom end of one side of drain pipe 10, and drain pipe 10 is installed on one side of valve 9;

[0034] The handle 7 is rotatably connected to the top of both sides of the collection tank 1, and the two sides of the collection tank 1 are fixed with a fixing seat 3.

[0035] The lid 8 is threaded to the top of the collection tank 1, and the top of the lid 8 is connected to a bellows 11.

[0036] The filter structure 6 is located at the bottom end of the bellows 11 and is used to filter the fissure water that enters the bellows 11.

[0037] The connecting pipe 4 is set at the bottom of the filter structure 6, and the bottom end of the connecting pipe 4 is threadedly connected to the insertion pipe 2. The bottom end of the insertion pipe 2 is provided with an inlet 13, and the bottom end of the insertion pipe 2 is fixed with a baffle 12.

[0038] An expansion structure 5 is disposed on the outside of the connecting pipe 4. The expansion structure 5 includes a connecting piece 503 rotatably connected to the outside of the connecting pipe 4, a rubber sleeve 502 sleeved on the outside of the connecting piece 503, and an adjustment component disposed on the outside of the connecting pipe 4.

[0039] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the adjusting assembly further includes a threaded tube 501 threaded to the outside of the connecting tube 4, a push ring 505 fixed to the bottom end of the threaded tube 501, and a retaining ring 504 fixed to the outside of the rubber sleeve 502. Several sets of connecting pieces 503 are arranged on the outside of the connecting tube 4, and these sets of connecting pieces 503 are evenly distributed on the outside of the connecting tube 4. The front cross-section of the push ring 505 has a funnel-shaped inclined structure, and the retaining rings 504 are evenly distributed on the outside of the rubber sleeve 502. By placing the rubber sleeve 502 at the tunnel fissure opening, and then rotating the screw tube 501, the screw tube 501 moves towards the connecting piece 503 through the threads on the surface of the connecting tube 4. At the same time, the push ring 505 pushes the connecting piece 503 to flip outward, so that the connecting piece 503 opens the rubber sleeve 502 and makes the rubber sleeve 502 contact the rock wall. The rubber sleeve 502 abuts against the rock wall to fix the position of the connecting tube 4 and the insertion tube 2. The retaining ring 504 increases the friction between the rubber sleeve 502 and the rock wall, so that the rubber sleeve 502 is fixed firmly.

[0040] like Figure 4As shown, in a preferred embodiment, based on the above method, the filter structure 6 further includes a first rotating sleeve 603 rotatably connected to the top of the connecting pipe 4, a cover 605 fixed to the top of the first rotating sleeve 603, a filter screen 604 fixed inside the cover 605, a second rotating sleeve 606 fixed to the top of the cover 605 and rotatably connected to the corrugated pipe 11, a drain port 602 fixed to one side of the cover 605, and a debris shell 601 threaded to the outside of the drain port 602. The connecting pipe 4 and the corrugated pipe 11 are connected through the cover 605. The front cross-section of the filter screen 604 has an inclined structure. By pulling the cover 605, the first rotating sleeve 603 is driven... 3 and the second rotating sleeve 606 rotate outside the connecting pipe 4 and the corrugated pipe 11, so that the debris shell 601 is located below the cover 605. When the fissure water inside the connecting pipe 4 is introduced into the interior of the cover 605, it is filtered through the filter screen 604, causing the gravel and silt to accumulate on one side of the filter screen 604. At the same time, due to the inclined design of the filter screen 604, the gravel and silt attached to the surface of the filter screen 604 are easily affected by the water flow and gravity and fall into the interior of the debris shell 601, so that the filter screen 604 can remain unobstructed. After collection, the debris shell 601 is rotated to separate the debris shell 601 from the drain outlet 602, so as to facilitate the discharge or treatment of the gravel and silt.

[0041] Specifically, when using the tunnel fissure water collection device: hold the connecting pipe 4 and insert the insertion pipe 2 horizontally or with the tail end downward into the tunnel fissure, so that the insertion pipe 2 is in direct contact with the tunnel fissure water. Rotate the expansion structure 5 against the rock wall and fix the connecting pipe 4 at the outlet of the tunnel fissure. Place the collection tank 1 below the insertion pipe 2. Guide the tunnel fissure water into the interior of the insertion pipe 2 through the inlet 13. At the same time, the baffle 12 prevents large-volume gravel from blocking the inlet 13 and guides the tunnel fissure water on the outside of the inlet 13 so that it enters the interior of the inlet 13. Then, the tunnel fissure water enters the interior of the corrugated pipe 11 through the connecting pipe 4 and the filter structure 6. The filter structure 6 filters the foreign matter in the tunnel fissure water. The tunnel fissure water is collected through the collection tank 1. Opening the valve 9 can discharge the tunnel fissure water.

[0042] When fixing the device, the rubber sleeve 502 is placed at the tunnel fissure opening, and then the screw tube 501 is rotated so that the screw tube 501 moves through the thread on the surface of the connecting tube 4 toward the connecting piece 503. At the same time, the push ring 505 pushes the connecting piece 503 to flip outward, so that the connecting piece 503 opens the rubber sleeve 502 and makes the rubber sleeve 502 contact the rock wall. The position of the connecting tube 4 and the insertion tube 2 is fixed by the rubber sleeve 502 against the rock wall. The retaining ring 504 increases the friction between the rubber sleeve 502 and the rock wall, so that the rubber sleeve 502 is fixed firmly.

[0043] By pulling the cover 605, the first rotating sleeve 603 and the second rotating sleeve 606 rotate outside the connecting pipe 4 and the corrugated pipe 11, so that the debris shell 601 is located below the cover 605. When the fissure water inside the connecting pipe 4 is introduced into the interior of the cover 605, it is filtered by the filter screen 604, causing the gravel and silt to accumulate on one side of the filter screen 604. At the same time, due to the inclined design of the filter screen 604, the gravel and silt attached to the surface of the filter screen 604 are easily affected by the water flow and gravity and fall into the interior of the debris shell 601, so that the filter screen 604 can remain unobstructed. After collection, the debris shell 601 is rotated to separate the debris shell 601 from the drain outlet 602, so that the gravel and silt can be discharged or studied and treated.

[0044] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
