Description

Technical Field

[0001] This utility model relates to the field of shaft technology, and in particular to a zoned flexible seismic lining structure for cross-fault shafts. Background Technology

[0002] In water conservancy, mining, transportation and other engineering projects, vertical shafts are key structures connecting the surface and underground space. When seismic activity causes fault displacement, the lining of the vertical shaft spanning the fault will be subjected to huge shear and tensile and compressive deformation, which is very easy to cause brittle failure, leading to shaft collapse, loss of function, and even secondary disasters. Existing shaft linings mostly adopt an integral rigid structure design, using high-strength concrete, steel mesh, and other materials to enhance the structural load-bearing capacity. However, this type of rigid lining structure has the following shortcomings: 1. The rigid structure has poor deformation capacity. When encountering geological disasters such as earthquakes, the relative displacement on both sides of the fault zone will be directly transmitted to the lining structure, causing cracks, spalling, or even overall collapse of the lining, seriously affecting the normal use of the shaft and the safety of surrounding projects; 2. The integral rigid structure is difficult to adapt to the long-term micro-deformation of the fault zone, and is prone to structural fatigue damage due to stress concentration, reducing the service life of the lining; 3. The waterproofing and seismic design of traditional linings are independent. During fault activity, the rigid connection parts are prone to sealing failure, causing groundwater leakage and further aggravating structural corrosion and damage. In view of the above, this application proposes a zoned flexible seismic lining structure for cross-fault shafts. Summary of the Invention

Multiple connecting reinforcing bars are fixedly connected to the side of the vertical reinforcing bars away from the steel rings. The multiple connecting reinforcing bars are welded and fixed to the inside of the composite waterproof ring. A second concrete is provided on the inside of the composite waterproof ring. The multiple vertical reinforcing bars, multiple steel rings and multiple connecting reinforcing bars are all embedded in the second concrete.

[0007] Preferably, the transition zone lining includes a first carbon fiber reinforced mesh ring and a second carbon fiber reinforced mesh.

The multiple vertical prestressed steel bars are arranged in a ring, and the multiple horizontal prestressed steel bars are respectively fixed to both sides of the corresponding vertical prestressed steel bars. The ends of two opposing horizontal prestressed steel bars that are far apart from each other are welded and fixed to the inner side of the first carbon fiber reinforced mesh ring and the outer side of the second carbon fiber reinforced mesh ring, respectively. A rubber waterproof ring is adhesively fitted inside the second carbon fiber reinforced mesh ring.

[0008] Preferably, the flexible connection area includes two stainless steel corrugated pipes, with an elastic foam layer filling the space between the two stainless steel corrugated pipes.

[0009] Preferably, the sealing connection mechanism includes connecting rings. The sides of the two connecting rings that are close to each other are welded and fixed to the top and bottom ends of the two stainless steel corrugated pipes, respectively. The sides of the two connecting rings that are far apart from each other are bonded and fixed with sealing rings.

[0012] Compared with existing technologies, the beneficial effects of this utility model are: 1. Through the zoning design of "rigid zone - transition zone - flexible connection zone", the stainless steel corrugated pipe and elastic foam layer in the flexible connection zone bear the relative displacement of the fault. The external impact is offset by adaptive deformation and energy dissipation. At the same time, the transition zone uses carbon fiber mesh and prestressed steel bars to achieve stable stress transfer, avoid structural brittle failure caused by stress concentration, effectively resist the damage to the lining caused by geological disasters such as earthquakes, and ensure the normal use of the shaft and the safety of surrounding projects. 2. The fiber-reinforced concrete and carbon fiber mesh in the transition zone have excellent toughness and can undergo slight elastic deformation with minor deformation of the fault without permanent damage. The elastic foam layer in the flexible connection zone can also adapt to long-term deformation through continuous compression and rebound, avoiding fatigue cracks caused by repeated stress on the structure and significantly extending the service life of the lining structure. 3. The rigid zone is constructed with a high-strength load-bearing system through shear-resistant steel mesh, pre-cast reinforcement layer and X-shaped reinforcing bars to ensure the load-bearing capacity of the structural foundation; the transition zone and flexible connection zone, through material properties and structural design, achieve deformation adaptation without weakening the overall load-bearing stability, and achieve the synergistic unity of "rigid load-bearing" and "flexible deformation resistance" to meet the comprehensive requirements of cross-fault shaft for structural performance. 4. A three-layer waterproof barrier is formed by the rigid zone composite plate waterproof ring, the transition zone rubber waterproof ring, and the flexible connection zone sealing ring. The sealing connection mechanism is tightened with bolts and elastically fits the sealing ring to ensure the waterproof sealing of the connection part, effectively blocking the infiltration of groundwater and avoiding structural corrosion and strength reduction caused by water seepage, and further ensuring the long-term stable operation of the lining structure. This utility model adopts a partitioned design of "rigid zone - transition zone - flexible connection zone". The rigid zone ensures the foundation bearing capacity, the transition zone smoothly transmits force, and the flexible connection zone adaptively deforms to offset fault misalignment and avoid structural damage. At the same time, it can adapt to long-term micro deformation to extend the service life. In addition, it blocks water seepage through a multi-layer waterproof system, effectively solving the core defects of existing rigid linings and taking into account both rigid bearing capacity and flexible deformation resistance requirements.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 A partitioned flexible seismic lining structure for cross-fault vertical shafts includes a partitioned flexible seismic lining structure main body installed in the fault zone of vertical shaft 100. The partitioned flexible seismic lining structure main body includes two rigid zone linings 1, two transition zone linings 2, and a flexible connection zone 3. The flexible connection zone 3 is located between the two transition zone linings 2, and the two transition zone linings 2 are located between the two rigid zone linings 1. The rigid zone linings 1, transition zone linings 2, and flexible connection zone 3 are arranged along the axis of vertical shaft 100. The top and bottom of the flexible connection zone 3 are fixedly connected to the sides of the two transition zone linings 2 that are close to each other by a sealing connection mechanism. The rigid lining 1 includes a shear-resistant steel mesh 101, within which a pre-cast reinforcement layer is provided. A composite waterproof ring 102 is fixedly fitted onto the outside of the pre-cast reinforcement layer to block groundwater infiltration. Multiple X-shaped reinforcing ribs 106 are fixedly connected between the outer side of the composite waterproof ring 102 and the inner wall of the shear-resistant steel mesh 101. A first concrete 107 is poured between the outer side of the composite waterproof ring 102 and the inner wall of the shear-resistant steel mesh 101. All reinforcing bars 106 are pre-embedded in the first concrete 107. The setting of multiple X-shaped reinforcing bars 106 is used to enhance the bending resistance. The top left side of the shear steel mesh 101 is fitted with a first L-shaped pouring pipe 108. The right side of the first L-shaped pouring pipe 108 is located between the composite waterproof ring 102 and the shear steel mesh 101. The first concrete 107 can be poured between the composite waterproof ring 102 and the shear steel mesh 101 through the first L-shaped pouring pipe 108 to ensure that the first concrete 107 is densely filled. The precast reinforcement layer includes multiple vertical steel bars 103 and multiple steel rings 104 arranged in a ring. The multiple vertical steel bars 103 are all welded and fixed to the outside of the multiple steel rings 104. Multiple connecting steel bars are fixedly connected to the side of the vertical steel bars 103 away from the steel rings 104. The multiple connecting steel bars are all welded and fixed to the inside of the composite waterproof ring 102. The inside of the composite waterproof ring 102 is provided with a second concrete 105. The multiple vertical steel bars 103, multiple steel rings 104 and multiple connecting steel bars are all embedded in the second concrete 105. The transition zone lining 2 includes a first carbon fiber reinforced mesh ring 201 and a second carbon fiber reinforced mesh 202. Fiber-reinforced concrete 205 is filled between the first carbon fiber reinforced mesh ring 201 and the second carbon fiber reinforced mesh 202. A second L-shaped pouring pipe 207 is embedded and fixed at the top left side of the first carbon fiber reinforced mesh ring 201. The right side of the second L-shaped pouring pipe 207 is located between the first carbon fiber reinforced mesh ring 201 and the second carbon fiber reinforced mesh 202. Fiber-reinforced concrete 205 is poured through the second L-shaped pouring pipe 207 to ensure full filling of the fiber-reinforced concrete 205. Multiple vertical prestressed steel bars 203 and multiple horizontal prestressed steel bars 204 are pre-embedded in the 05. The multiple vertical prestressed steel bars 203 are arranged in a ring. The multiple horizontal prestressed steel bars 204 are respectively fixed on both sides of the corresponding vertical prestressed steel bars 203. The ends of two opposite horizontal prestressed steel bars 204 that are far apart from each other are welded and fixed to the inner side of the first carbon fiber mesh ring 201 and the outer side of the second carbon fiber mesh 202, respectively. A rubber waterproof ring 206 is bonded and sleeved inside the second carbon fiber mesh 202 to achieve a secondary seal. The flexible connection area 3 includes two stainless steel corrugated pipes 301, and an elastic foam layer 302 is filled between the two stainless steel corrugated pipes 301. Utilizing the elastic properties of the stainless steel corrugated pipes 301, they can adapt to deformation. The setting of the elastic foam layer 302 can absorb deformation energy through compression / rebound, and jointly offset the relative displacement of fault slip to avoid structural damage. The sealing connection mechanism includes connecting rings 303. The sides of two connecting rings 303 that are close to each other are welded and fixed to the top and bottom ends of two stainless steel bellows 301, respectively. Sealing rings 304 are bonded and fixed to the sides of two connecting rings 303 that are far from each other. The sides of two sealing rings 304 that are far from each other are in close contact with the sides of two transition zone linings 2 that are close to each other. Connecting sleeves 305 are welded and fixed to the sides of two first carbon fiber reinforced mesh rings 201 that are close to each other. Annular grooves are formed on the sides of two connecting rings 303 that are far from each other. The connecting sleeves 305 are movably fitted into the corresponding annular grooves. Multiple threaded grooves are formed on the outer side of the connecting sleeves 305 in an annular shape, and T-shaped fixing bolts are threaded into the threaded grooves. 306. The connecting ring 303 is threaded onto the corresponding multiple T-shaped fixing bolts 306. T-shaped bolt holes are opened on the outer wall of the annular groove. The T-shaped bolt holes are in contact with the corresponding T-shaped fixing bolts 306. The inner wall of the connecting sleeve 305 is in contact with the outer side of the corresponding sealing ring 304. Through the cooperation of the T-shaped fixing bolts 306, the connecting sleeve 305 and the connecting ring 303, a sealed connection between the transition zone lining 2 and the flexible connection zone 3 can be achieved. The sealing ring 304 expands when exposed to water, which can enhance its sealing characteristics. The sealing ring 304 can maintain the basic seal in a dry state and can further fill the gaps through expansion when groundwater seeps in, avoiding the sealing failure of the flexible connection zone due to deformation. This utility model adopts a partitioned design of "rigid zone - transition zone - flexible connection zone". The rigid zone ensures the foundation bearing capacity, the transition zone smoothly transmits force, and the flexible connection zone adaptively deforms to offset fault misalignment and avoid structural damage. At the same time, it can adapt to long-term micro deformation to extend the service life. In addition, it blocks water seepage through a multi-layer waterproof system, effectively solving the core defects of existing rigid linings and taking into account both rigid bearing capacity and flexible deformation resistance requirements.

[0017] It should be noted that the first carbon fiber reinforcing mesh 201 and the second carbon fiber reinforcing mesh 202 have the characteristics of "high strength + high toughness + corrosion resistance". Compared with traditional steel bars, their tensile strength is 3-5 times that of ordinary steel bars, and they are not easy to break after deformation. They can meet the requirements of "force transmission + micro-deformation" in the transition zone. The stainless steel corrugated pipe 301 can preferably be made of 316L corrosion-resistant corrugated pipe to avoid long-term erosion by groundwater that could cause the stainless steel corrugated pipe 301 to fail, while ensuring its durability under repeated deformation. The elastic foam layer 302 is preferably made of closed-cell EPDM rubber foam or polyurethane closed-cell foam. These materials not only have stable compression and resilience performance and can absorb deformation energy for a long time, but also block water penetration, preventing the foam from losing elasticity after absorbing water, and ensuring the dual function of "deformation + waterproofing" in the flexible area.

[0018] Working principle: When the fault zone shifts due to earthquakes or other reasons, the deformation force of the surrounding rock around the shaft 100 is first transferred to the outer rigid lining 1. The outer shear-resistant steel mesh 101 acts as a rigid skeleton to provide shear resistance. The inner layer, composed of vertical steel bars 103, steel rings 104, and second concrete 105, forms a dense compressive core. The X-shaped reinforcing bars 106 between the outer side of the composite waterproof ring 102 and the shear-resistant steel mesh 101 are embedded in the first concrete 107 to enhance bending resistance. The composite waterproof ring 102 blocks groundwater infiltration, the first L-shaped pouring pipe 108 ensures the dense filling of the first concrete 107, and the rigid zone receives and initially disperses external forces; undispersed stress is transferred to the transition lining 2. The first carbon fiber mesh ring 201 and the second carbon fiber mesh 202 form a double-layer skeleton with high toughness. The fibers in the fiber concrete 205 block crack propagation, and the pre-embedded vertical prestressed steel bars 203 and horizontal prestressed steel bars 204 offset tensile and compressive stresses through tensioning, achieving "rigid orientation". The "flexible" stress transition is smooth, while the rubber waterproof ring 206 forms secondary waterproofing. The second L-shaped casting pipe 207 is used to ensure that the fiber concrete 205 is fully filled. Finally, the stress is transferred to the flexible connection zone 3. The two stainless steel corrugated pipes 301 adaptively deform along the axis and radial direction. The intermediate elastic foam layer 302 absorbs deformation energy through compression / rebound, and together offsets the relative displacement of the fault to avoid structural damage. At the same time, the connecting sleeve 305 in the transition zone of the sealing connection mechanism is embedded in the annular groove of the flexible zone connecting ring 303. It is uniformly fixed circumferentially by the T-shaped fixing bolt 306 to prevent detachment. The connecting ring 303 and the sealing ring 304 in the transition zone are elastically compressed under the bolt tightening force, tightly filling the gap and maintaining fit with slight deformation. Together with the rigid zone and the transition zone waterproof structure, a three-layer waterproof system is formed, which ultimately achieves the coordinated work of "rigid bearing - transition buffer - flexible deformation - sealing waterproofing", thereby realizing the adaptive seismic resistance and waterproofing function for the geological activity of the fault zone and ensuring the stable operation of the cross-fault shaft 100.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
