Description

Technical Field

[0001] The invention relates to a tunnel lining structure joint water-stopping device, in particular to a reinforced deformed embedded water-stopping strip structure. Background Art

[0002] Tunnel leakage is an important reason for the decrease in the bearing capacity of the tunnel lining. Since deformation joints and construction joints are inevitably left during tunnel construction, these gaps will become seepage channels for groundwater, posing a safety hazard to tunnel operation. During construction, waterstop strips are generally set at the gaps to effectively seal the groundwater in the gaps.

[0003] However, the deformation capacity of existing ordinary waterstops is limited. When encountering earthquakes or other strong natural disasters, the ordinary waterstops fixed in the construction joints will also produce corresponding displacements due to the displacement of the lining to the sides or tangential displacement. This displacement may be unbearable for ordinary waterstops and may cause them to break. At the same time, during the use of ordinary waterstops, groundwater will be stored behind the waterstop structure, which will produce pressure on the waterstops. Groundwater may seep out from the connection gaps between the waterstops, thereby affecting the tunnel lining structure.

[0004] Therefore, it is necessary to propose new measures to overcome the above-mentioned defects. Summary of the invention

[0052] Embodiment 1:

[0053] In this embodiment, the structure includes a water stop portion 300 and a compression module 500 .

[0054] The water stop portion 300 is located in the deformation joint area 200 of the tunnel lining portion 100, and includes a first water stop strip 301 and a second water stop strip 302 arranged on the left and right and in close contact. The first water stop strip 301 and the second water stop strip 302 are connected as a whole at the top and separated at the bottom. Both contact surfaces are provided with transverse protrusions and are plugged into each other to form a non-linear square tooth contact form.

[0055] There is a cavity between the upper parts of the first water stop 301 and the second water stop 302, and a rubber block 304 is placed therein, which can seal the upper part of the contact surface of the first water stop 301 and the second water stop 302 to prevent water from penetrating. The cavity is located below the part where the top of the first water stop 301 and the second water stop 302 are connected as an integral part, and a second extrusion bag 504 is arranged on the upper part of the rubber block 304 in the cavity. A vertical first air channel 5021 is arranged in the first water stop 301 and the second water stop 302, and a second air channel 503 connecting the first air channel 5021 and the second extrusion bag 504 is arranged. The compression module 500 includes a first extrusion bag 501, and a groove is arranged on the top surface where the top of the first water stop 301 and the second water stop 302 are connected as an integral part, which is a semicircular concave shape. The first extrusion bag 501 is located in the groove, and the tops of the first air channels 5021 on both sides are connected to the first extrusion bag 501. The first air channel 5021 and the second air channel 503 are collectively referred to as the air groove 502, and the second air channel 503 is Z-shaped.

[0056] When the top of the water stop portion 300 is subjected to pressure, the water stop portion 300 is deformed, the tops of the first water stop 301 and the second water stop 302 are pressed downward, the upper parts move toward each other, and the lower parts move outward to the left and right sides respectively, and expand outward to present an eight-shaped shape. At the same time, the first extrusion bag 501 is squeezed, and the internal gas enters the second extrusion bag 504 through the first air channel 5021 and the second air channel 503. The second extrusion bag 504 expands and squeezes the rubber block 304 downward, thereby strengthening the sealing effect between the first water stop 301 and the upper part of the second water stop 302.

[0057] In this embodiment, an extension plate is provided on the outer side of the bottom of each of the first water stop 301 and the second water stop 302 , and a fixing member 303 is provided on the extension plate.

[0058] Embodiment 2:

[0059] This embodiment adds a rubber bellows 305 on the basis of the embodiment 1.

[0060] The transverse convex end surface of the first water stop 301 is provided with an indented hole, and a rubber bellows 305 is provided in the indented hole. The transverse ends of the rubber bellows 305 are respectively fixed to the bottom of the indented hole and the second water stop 302, and transverse air passages connecting the first air passage 5021 and the rubber bellows 305 are provided in the first water stop 301 and the second water stop 302.

[0061] When the top of the water stop portion 300 is subjected to pressure, the lower parts of the first water stop strip 301 and the second water stop strip 302 will move outward to the left and right sides respectively, and the rubber bellows 305 is connected between the two to limit the continuous increase of the distance between the two.

[0062] Embodiment 3:

[0063] This embodiment adds a connection module 600 on the basis of Embodiment 2.

[0064] The connection module 600 includes a connection rope 601, a gravity ball 603 and a rubber rod 602. The portion where the first water stop 301 and the second water stop 302 are connected as one is provided with a connection rope groove, which is located below the first extrusion bag 501 and is connected to the first air passages 5021 on both sides. The connection rope 601 is located in the connection rope groove and is Y-shaped. The outer diameters of the two ends of the connection rope 601 are smaller than the outer diameter of the middle, and the two ends are thin and the middle is thick. The gravity ball 603 is located at the top of the first air passage 5021, and the connection rope 601 is intercepted below the gravity ball 603. A vertical connecting hole is arranged between the middle of the connecting rope groove and the cavity between the first waterstop 301 and the upper part of the second waterstop 302, a closed hole is arranged at the position of the second extrusion bag 504 corresponding to the connecting hole, a plug hole is arranged at the position of the rubber block 304 corresponding to the connecting hole, and the rubber rod 602 is located in the connecting hole, the closed hole and the plug hole; the top of the rubber rod 602 is connected to the connecting rope 601, and the bottom is connected to the rope, the rope passes through the horizontal protrusion of the first waterstop 301, and passes through the horizontal airway and the rubber corrugated bag 305 to be connected to the second waterstop 302.

[0065] When the top of the water stop 300 is under pressure, the lower parts of the first water stop 301 and the second water stop 302 will move outward to the left and right sides respectively, and the second water stop 302 pulls the rope to the right, pulling the rubber rod 602 downward, thereby pulling the connecting rope 601 downward, and both ends of the connecting rope 601 move toward the center. When the thinner part moves to the position of the gravity ball 603, the connecting rope 601 no longer blocks the gravity ball 603, and the gravity ball 603 falls into the first airway 5021. The inner diameter value of the transverse airway is smaller than the inner diameter value of the first airway 5021, so the gravity ball 603 will not enter the transverse airway. The fall of the gravity ball 603 increases the weight of the lower parts of the first water stop 301 and the second water stop 302, which can limit the two from continuing to move outward to both sides. When the connecting rope 601 is not pulled, it will block the gravity ball 603, so that it stays at the top of the first airway 5021.

[0066] In this embodiment, retaining rings 5022 are installed on both the upper and lower sides of the inner cavity of the first airway 5021, and the inner diameter of the upper retaining ring 5022 is greater than the inner diameter of the lower retaining ring 5022. When the gravity ball 603 falls from the inside of the first airway 5021, it will pass through the two retaining rings 5022 in sequence, and the two retaining rings 5022 will distribute the gravity ball 603 in three areas on the first airway 5021. The number of gravity balls 603 can be three, and the sizes of the three gravity balls 603 are different, increasing from bottom to top.

[0067] In this embodiment, an extension plate is also provided on the outer side of the top of the first waterstop 301 and the second waterstop 302, and the connecting rope 601 and the connecting rope groove both extend into the extension plate.

[0068] Embodiment 4:

[0069] This embodiment is based on the third embodiment, and a pulling component 700 is added.

[0070] The transverse protrusion of the second water stop 302 is provided with a transverse through hole, which is connected to the first air channel 5021 in the second water stop 302, and a pulling assembly 700 is provided in the transverse through hole. The pulling assembly 700 includes a clamping rod 701, and a pushing protrusion is provided at a position of the first air channel 5021 corresponding to the clamping rod 701.

[0071] When the gravity ball 603 falls into the first air channel 5021 , the weight of the lower parts of the first waterstop 301 and the second waterstop 302 increases and both move inward, pushing the protrusion to push the clamping rod 701 to the left, causing it to move to the left and be clamped into the interior of the first waterstop 301 .

[0072] Embodiment 5:

[0073] This embodiment optimizes the structure of the pulling component 700 on the basis of the fourth embodiment.

[0074] The opening of the transverse through hole connected to the first airway 5021 is provided with a tapered circular tube 705, and the inner end of the tapered circular tube 705 has an opening, and the stop rod 704 is inserted into the opening. The end of the clamping rod 701 close to the stop rod 704 has an enlarged head, and the enlarged head is clamped by the L-shaped stop rod 703. The L-shaped stop rod 703 is located in a rod groove with a margin set in the horizontal line protrusion, and is hinged in the rod groove at the corner. The outer end of the L-shaped stop rod 703 is located in the transverse through hole, and is horizontally opposite to the stop rod 704. The outer periphery of the clamping rod 701 is covered with a spring 702, and the two ends of the spring 702 are respectively connected to the transverse through hole and the enlarged head. The end of the clamping rod 701 is tapered and provided with a backward barb.

[0075] When the conical tube 705 is squeezed by the gas in the first air channel 5021 and the gravity ball 603, the rod 704 inside it is pushed to move to the left, squeezing the L-shaped blocking rod 703, forcing the L-shaped blocking rod 703 to release the fixation of the clamping rod 701, and the clamping rod 701 is quickly driven to be clamped into the first water stop 301 by the elastic force of the spring 702. The barbs will simultaneously enter the first water stop 301 to achieve the connection with the first water stop 301.

[0076] Embodiment 6:

[0077] In this embodiment, based on the fifth embodiment, a water sensor 400 is disposed between the lower parts of the first water stop 301 and the second water stop 302 .

[0078] The structure of the present invention has the following technical features:

[0079] 1. The present invention strengthens the deformation capacity of the waterstop part and avoids the phenomenon of water infiltration through the coordination of structures such as the waterstop part and the compression module. When the groundwater is continuously pressurized, the top ends of the first waterstop and the second waterstop move towards each other and simultaneously squeeze the first extrusion bag, causing the internal gas to enter the interior of the second extrusion bag through the first air channel and the second air channel, and forcing the second extrusion bag to expand and squeeze the rubber block, thereby increasing the sealing effect on the top ends of the first waterstop and the second waterstop. The snap-fit ​​design of the first waterstop and the second waterstop increases the sealing performance of the deformation joint area and strengthens the deformation capacity of the first waterstop and the second waterstop.

[0080] 2. The present invention increases the tightness of the fit between the first waterstop and the second waterstop and improves the deformation sealing effect through the coordination of structures such as rubber rods and rubber bellows. When the lower ends of the first waterstop and the second waterstop are deformed and pulled in an eight-shape away from each other, the rubber bellows are simultaneously pulled into an unfolded state to connect the first waterstop and the second waterstop to avoid gaps. At the same time, the connecting rope is pulled to release the obstruction to the gravity ball, causing it to fall through the retaining ring in the inner cavity of the first airway, resulting in the three gravity balls being located in the upper, middle and lower areas respectively, providing downward gravity and increasing the resistance of the first waterstop and the second waterstop to deformation caused by being pulled.

[0081] 3. The present invention cooperates with structures such as a pulling component and a water immersion sensor, so that the adjacent ends of the first waterstop and the second waterstop are pulled toward each other after deformation, thereby minimizing the effect of water penetration and detecting the damaged position. When the gas and the gravity ball fall inside the first airway, they will contact the resistance rod through the raised arc surface of the inner wall, causing it to push the L-shaped barrier rod to flip and release the fixation of the clamping rod, so that it can be quickly inserted from the inside of the second waterstop to the inside of the first waterstop, thereby increasing the relative pulling force between the first waterstop and the second waterstop. When the first waterstop and the second waterstop are damaged and water unfortunately penetrates, the water immersion sensor will monitor the water flow, find the leakage position, and perform repairs.

[0082] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
