Description

Technical Field

[0001] This invention relates to the field of channel technology, specifically to a submerged water plant channel system and a seismic control method. Background Technology

[0002] Submerged water treatment plants (or sewage treatment plants) are a new type of underground space structure developed in recent years. They are generally divided into two underground levels. The channel is located at the top of the second basement level of the submerged water treatment plant. It is a rectangular pipe gallery structure constructed with reinforced concrete, consisting of the pool walls and surrounding beams and slabs, forming an integrated reinforced concrete structure.

[0003] Typically, the channel's sidewalls extend to the top, connecting to the top beam slab. The top of the channel is the top beam slab, and the main body of the channel is enclosed by the channel bottom, sidewalls, and the top beam slab of this level. Manholes are installed in the top beam slab as needed. The main load of the channel is transferred to the top beam slab, generally in a suspended load-bearing manner.

[0004] Existing reinforced concrete channel structures have many problems in design, construction, and subsequent renovation. For example:

[0005] (1) The reinforced concrete channel structure is solidified, the space is compact and limited, and the conditions for renovation are restricted. It usually requires demolition and reconstruction of the reinforced concrete channel, which can easily damage the structure of the joint area and affect the calculation model of this area, making it difficult for the original structure to pass the verification. Renovation or maintenance requires water to be shut off, and the concrete curing period is long, making it impossible to quickly restore water flow, resulting in high renovation and maintenance costs.

[0006] (2) The channel is the connecting passage and important component of the water plant. Damage to it will directly lead to the shutdown of the water plant. Compared with the pool, the channel area is a structurally weak part and is easily damaged during earthquakes. However, there is no mature earthquake-resistant design for the channels of the existing submerged water plant. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a submerged water plant channel system and a seismic control method. The channel system is divided into frame support modules and lightweight channel modules. The frame support modules provide load-bearing and primary seismic resistance, while the lightweight channel modules reduce their self-weight load through lightweight design. The overall structure is simplified and relatively independent of adjacent structures such as the top beams and slabs. The channel is placed on the frame support modules, resulting in a clear force transmission path and a reasonable stress distribution, thus improving the channel system's load-bearing and seismic performance. The system's modification, reconstruction, and repair have minimal impact on surrounding structures. New construction and renovation can be more flexible and diverse in layout, reducing concrete curing and allowing for uninterrupted or rapid restoration of water supply. Construction is convenient, fast, and cost-effective. The lightweight channel modules can be prefabricated and assembled, making installation and replacement easier. This seismic control method can drain water from the channel before or during an earthquake, mitigating or avoiding complex "solid-liquid" seismic responses and thus reducing earthquake damage to the channel system.

[0008] The technical solution adopted in this invention is as follows:

[0009] A submerged water plant channel system includes a frame support module and a lightweight channel module;

[0010] The frame support module includes horizontally arranged beam members and vertically arranged column members; the beam members and the column members form a frame channel; or, the beam members, the column members, and the pool sidewall form a frame channel.

[0011] The lightweight channel module includes one channel or multiple channels arranged in parallel, the channel being composed of several lightweight channel segments connected together; the channel is detachably installed within the frame channel.

[0012] In one embodiment of this application, the beam member includes a main beam and a secondary beam:

[0013] The main beam is arranged along the length of the channel;

[0014] The secondary beam is arranged perpendicular to the length direction of the channel, and the secondary beam connects to the main beam, or the secondary beam connects the main beam and the pool sidewall;

[0015] The column components include main columns and secondary columns:

[0016] The main column is vertically installed below the beam member, with its lower end connected to the bottom of the pool and its upper end connected to the main beam, serving as a support;

[0017] The secondary column is vertically arranged above the beam member, with its lower end connected to the main beam and its upper end extending to connect to the top beam plate, or its upper end extending but not connected to the top beam plate.

[0021] In one embodiment of this application, a vibration damping and isolation module is further included, the vibration damping and isolation module comprising: a first vibration damping and isolation support disposed at the bottom of the channel, a second vibration damping and isolation support disposed on both sides of the channel, and a third vibration damping and isolation support disposed at the upper part of the channel.

[0022] In one embodiment of this application, the first vibration damping and isolation bearing is a sliding friction bearing, including an upper bearing plate, a crown body and a lower bearing plate, wherein the upper bearing plate and the crown body, and the lower bearing plate and the crown body are in sliding surface engagement.

[0023] The second vibration damping support is a helical spring support, which is set along the horizontal direction of the channel cross-section, with one end connected to the side wall of the channel and the other end connected to the column member or the side wall of the pool.

[0024] The third seismic isolation bearing is a buckling-restrained bearing, which is set in an oblique upward direction along the cross-section of the channel, with one end connected to the upper part of the side wall of the channel and the other end connected to the top beam plate.

[0025] In one embodiment of this application, a channel support plate is further included, the channel support plate being located between the beam member and the channel;

[0026] The upper seat plate is located at the bottom of the channel, and the lower seat plate is located on the upper side of the channel support plate. The upper seat plate and the lower seat plate are respectively provided with arc-shaped corrugated grooves. The grooves of the arc-shaped corrugated grooves are parallel to each other and are arranged perpendicular to the length direction of the channel.

[0027] The crown is a cylindrical crown, which is located in the groove of the arc-shaped corrugated groove and slides against the upper seat plate and the lower seat plate.

[0028] In one embodiment of this application, the upper seat plate, the lower seat plate, and the crown are made of chromium-containing stainless steel.

[0029] The contact surfaces of the arc-shaped corrugated groove and the crown are coated with polytetrafluoroethylene.

[0030] In one embodiment of this application, a baffle plate is provided in the channel, and the connection position of the second vibration damping support to the channel corresponds to the position of the baffle plate and is located in the same cross-section;

[0032] In one embodiment of this application, a drainage hole is provided on the side wall of the channel, and a quick-opening gate is installed in the drainage hole; a quick-closing gate is provided at the inlet of the channel; both the quick-opening gate and the quick-closing gate are electrically connected to and associated with the controller.

[0033] Alternatively, the channel may have an overflow port on the end sidewall and / or top wall, the overflow port being set above the normal water level and equipped with a reversible cover.

[0034] The present invention also provides a seismic control method for a channel system, comprising a submerged water plant channel system as described in any of the above claims, wherein the controller of the channel system is connected to an earthquake early warning system, and the method comprises the following steps:

[0035] The controller receives earthquake early warning information from the earthquake early warning system via wired and / or wireless means;

[0036] When the controller does not receive earthquake early warning information, the channel system operates normally;

[0037] When the controller receives earthquake early warning information, it determines whether to perform adjustment actions based on the earthquake early warning information. If yes, it controls the quick-closing gate at the channel inlet of the lightweight channel module to close and controls the quick-opening gate at the channel drainage outlet of the lightweight channel module to open; otherwise, the channel system operates normally.

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0039] 1. The sunken water plant channel system of this application is divided into frame support modules and lightweight channel modules. The frame support structure is simple and the channel is formed by assembling lightweight prefabricated channel sections. This avoids the complex support and dismantling work of narrow and long concrete channels with complex spatial changes, reduces construction difficulty, ensures construction quality, and saves project time. During operation, maintenance can be carried out in open space, avoiding the safety hazards of working in closed space.

[0040] 2. The frame support modules of the channel system serve as load-bearing and seismic resistance components, while the lightweight channel modules, through their lightweight design, reduce self-weight loads and related seismic effects. The channel, placed on the frame support modules, forms a separated structural system with a clear force transmission path and a reasonable stress distribution, resulting in better load-bearing and seismic performance of the channel system. The frame support modules and lightweight channel modules can respectively achieve the design objectives of "no collapse under major earthquakes" and "repairable under major earthquakes."

[0041] 3. The channel system offers excellent adaptability with minimal limitations in terms of space, design, and construction. The modular design allows for flexible spatial arrangement. The relatively independent nature of the channel system minimizes the impact on existing civil engineering structures during renovation and repair. Temporary supports can be used for the frame-support modules, and lightweight channel modules can be quickly assembled and replaced. During post-earthquake repairs or process modifications, the channel system can maintain or quickly restore water supply.

[0042] 4. Based on the characteristics of structural seismic response, this application sets up a seismic isolation bearing module between the frame support and the channel. This module is a reasonable combination of "sliding friction bearing + spring bearing + buckling restraint bearing", which respectively and in coordination / coupledly respond to the seismic forces in the three-phase vector direction, absorb and consume seismic energy during earthquakes, and reduce or avoid the damage caused by earthquakes to the channel system.

[0043] 5. Seismic control methods: By setting up quick-opening and quick-closing gates, earthquake early warnings are received before the arrival of seismic waves. This allows water in the channel to be discharged and prevents water from entering, which can reduce or avoid complex "solid-liquid" seismic responses. This reduces the damage caused by earthquakes to the channel system and also avoids the risk of water continuously overflowing from the damaged parts of the channel. Attached Figure Description

[0069] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention.

[0070] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0071] Example 1

[0072] This invention provides a sunken water plant channel system, which is installed on top of the underground space of a water plant or sewage treatment plant. It includes mutually separate frame support modules 100 and lightweight channel modules 200, etc.

[0073] like Figures 1 to 6 As shown, the frame support module 100 includes horizontally arranged beam members 110 and vertically arranged column members 120. The beam members 110 and column members 120 are assembled into a linear frame. When the frame support module 100 is directly located below the top beam slab 31 and does not contact the pool sidewall 32, the beam members 110 and column members 120, or the beam members 110, column members 120, and top beam slab 31, enclose a frame channel (not shown in the figure) that accommodates the lightweight channel module 200. When the frame support module 100 is located on the pool sidewall 32, as... Figure 1 As shown, beam member 110, column member 120 and pool side wall 32, or beam member 110, column member 120, pool side wall 32 and top beam slab 31 enclose a frame passage.

[0074] The lightweight channel module 200 can be one channel 210 or multiple channels 210. When there are multiple channels 210, they are arranged in parallel, and the multiple channels 210 can be arranged horizontally or vertically. Each channel 210 is composed of several lightweight channel segments connected together; all channels 210 can be detachably installed within the frame channel. Correspondingly, the frame channel can be divided into multiple channels according to the number of channels 210, with each channel accommodating one channel 210.

[0075] In one implementation, such as Figures 1 to 5 As shown, the beam member 110 includes several main beams 111 and secondary beams 112. The main beams 111 are arranged along the length of the channel 210, and their ends are connected to the pool sidewall 32 or the main columns 121 in the column member 120. The secondary beams 112 are arranged perpendicular to the length of the channel 210. When the frame support module 100 is directly located below the top beam slab 31 and does not contact the pool sidewall 32, the secondary beams 112 are perpendicularly connected to the main beams 111 at both ends and in the middle, and are not connected to the pool sidewall 32, and are evenly distributed along the length of the main beams 111. When the frame support module 100 is located on the pool sidewall 32, the secondary beams 112 are perpendicularly connected to the main beams 111 and the pool sidewall 32, and are evenly distributed along the length of the main beams 111. When the column member 120 is connected to the top beam slab 31, preferably the positions of the main beams 111 correspond to the beam positions of the top beam slab 31, and their arrangement is consistent.

[0076] like Figure 1 As shown, the column member 120 includes several main columns 121 and secondary columns 122. The main columns 121 are vertically positioned below the beam member 110, with their lower ends connected to the pool bottom and their upper ends connected to the main beam 111, serving as the primary support. Preferably, the main columns 121 are located at the connection point between the main beam 111 and the secondary beam 112. The secondary columns 122 are vertically positioned above the beam member 110, with their lower ends connected to the main beam 111 and their upper ends extending upwards. One implementation is to extend and connect to the beam of the top beam 31, meaning the secondary column 122 extends to the top; another implementation is that the upper end extends upwards but is not connected to the top beam 31, meaning the secondary column 122 does not extend to the top (not shown in the figure), and the frame passage is an open space. The secondary columns 122 mainly provide installation positions for the subsequent seismic isolation bearings, serving as channel limiting and seismic and damping supports.

[0077] According to long-term planning needs, in areas where there are renovation needs in the later stage, the secondary column 122 can be set without reaching the top, and the frame support module 100 can be attached to the main column 121, the main beam 111 and the pool side wall 32 to form an independent setting. The impact on the top beam 31 and other adjacent areas during renovation and reconstruction is small, which facilitates the implementation of the later renovation plan.

[0078] Specifically, when the frame support module 100 is directly located below the top beam slab 31 and does not contact the pool side wall 32, the beam member 110, the secondary column 122, and the top beam slab 31 enclose a frame channel; when the frame support module 100 is located on the pool side wall 32, the beam member 110, the secondary column 122, the pool side wall 32, and the top beam slab 31 enclose a frame channel.

[0079] In one embodiment, the frame support module 100 is a reinforced concrete component, constructed by on-site reinforced concrete pouring and curing. Furthermore, the vertical reinforcing bars at the top of the column 122 can be anchored into the top beam 31.

[0080] In another embodiment, the beam members 110 and main columns 121 in the frame support module 100 are reinforced concrete members, while the secondary columns 122 are steel members. If they are I-beam members, their I-beam flanges can provide an installation interface for subsequently installed seismic isolation bearings. The steel secondary columns 122 may or may not be connected to the top beam 31. When the secondary columns 122 are steel members, pre-embedded connectors are provided on the main beam 111 and / or the top beam 31 to connect with the secondary columns 122. The secondary columns 122 are made of steel and can be detachably connected via pre-embedded connectors, facilitating later channel modifications and maintenance, and offering strong applicability.

[0081] In another embodiment, all components of the frame support module 100 are steel structure supports, assembled from prefabricated steel components, and all steel components are designed for corrosion protection. When the frame support module 100 uses steel structure supports, installation and replacement operations are more convenient and faster, making it suitable for temporary channel projects.

[0082] The lightweight channel sections that make up channel 210 include thin-walled prestressed reinforced concrete sections, chemical material sections, steel sections, or composite sections of steel and chemical materials. Among them, chemical material sections include plastic-steel sections, and composite sections of steel and chemical materials include composite sections with steel structure hollow supports and chemical material linings.

[0083] The preferred channel 210 is composed of steel channel sections, which is a steel channel. When damaged by a strong earthquake, the steel channel can be quickly repaired by welding and other methods, so as to quickly restore operation.

[0084] Furthermore, such as Figure 7 As shown, when channel 210 is composed of steel sections, it is preferable that the steel sections be made of corrugated steel plates. Channel 210 made of corrugated steel plates has a stronger bottom plate load-bearing capacity, allowing for a reduction in the overall thickness of the steel plate and the use of reinforcing ribs. Furthermore, the length direction of channel 210 is the primary seismic fortification direction; during an earthquake, stress and deformation accumulate and superimpose along this direction. Channel 210 made of corrugated steel plates has a stronger deformation capacity, allowing for cyclic deformation during earthquakes, absorbing and dissipating seismic energy, and reducing or avoiding damage caused by earthquakes.

[0085] Channel 210 is assembled from several lightweight channel sections. Connections can be made using one or more methods, including bonding, fusion welding, welding, socket joints, flange connections, and bolted connections. If the lightweight channel section is a thin-walled prestressed reinforced concrete section, it can be connected using a prefabricated dry or wet method. Steel sections can be connected using welding, flange connections, or bolted connections as needed. Waterproofing measures should be implemented at the connection points of the lightweight channel sections.

[0086] In summary, the frame-support module 100 retains only beam and column components, eliminating the concrete wall panels and base slabs of traditional channels. The resulting frame-support structure preserves load-bearing and seismic-resistant components, featuring a simple structural form, clear force transmission path, and mature methods for force calculation and seismic analysis. The separation of the frame and channel, along with the assembly of the channel itself, significantly reduces the construction difficulty of complex and narrow channels, improves construction quality, and accelerates project progress. The lightweight design of the channel greatly reduces its self-weight, saving building materials and reducing seismic inertial forces, enabling the channel system to withstand stronger earthquakes. Furthermore, the frame-system channel system ensures that the main structure will not collapse rapidly under rare earthquake conditions, allowing for quick repair and restoration of water supply operations.

[0087] Example 2

[0088] like Figures 1 to 4 As shown, the submerged water plant channel system of Embodiment 1 also includes a seismic isolation module. Channel 210 is a rectangular cross-section channel, which can be either open at the top or closed at the top. The seismic isolation module includes a first seismic isolation support 41 at the bottom of channel 210, second seismic isolation supports 42 on both sides of channel 210, and a third seismic isolation support 43 at the top of channel 210. The first seismic isolation support 41, the second seismic isolation support 42, and the third seismic isolation support 43 are respectively installed in three directions to respectively and with coupling effects respond to seismic forces in the three-phase vector directions, thereby absorbing and dissipating seismic energy and achieving seismic isolation.

[0089] like Figure 2 and Figure 9 As shown, the first seismic isolation bearing 41 is a sliding friction bearing, which includes an upper bearing plate 411, a crown 412, and a lower bearing plate 413. The upper bearing plate 411 and the crown 412, and the lower bearing plate 413 and the crown 412, are in sliding surface fit. The sliding friction bearing installed at the bottom of the channel 210 generates seismic isolation performance through relative displacement and dissipates seismic energy through sliding friction, while also altering the natural period of the channel 210 to prevent resonance.

[0090] Furthermore, the channel system also includes a channel support plate 5, which is located between the beam member 110 and the bottom of the channel 210. In one embodiment, the two ends of the channel support plate 5 are supported on adjacent secondary beams 112, and the channel support plate 5 is disposed within the projected area of ​​the channel 210. In another embodiment, the two ends of the channel support plate 5 are supported on adjacent secondary beams 112, and the left and right sides are supported on the main beam 111 and the pool sidewall 32, covering the space between the beams.

[0091] The lower seat plate 413 of the sliding friction support is located on the top of the channel support plate 5, and the upper seat plate 411 is located at the bottom of the channel 210. Arc-shaped corrugated grooves 6 are correspondingly provided on the upper seat plate 411 and the lower seat plate 413. The grooves of the arc-shaped corrugated grooves 6 are parallel to each other and perpendicular to the length direction of the channel 210. A crown 412, a cylindrical crown located within the groove of the arc-shaped corrugated groove 6, slides against the upper seat plate 411 and the lower seat plate 413.

[0092] In another real-time configuration, the crown 412 is a flattened spherical crown, and the corresponding arc-shaped corrugated groove 6 consists of several circular grooves. When the crown 412 is a cylindrical crown, the upper seat plate 411 and the lower seat plate 413 can slide relative to each other along the length of the channel 210, forming a unidirectional sliding fit; when the crown 412 is a flattened spherical crown, the upper seat plate 411 and the lower seat plate 413 can slide relative to each other along both the length and width of the channel 210, forming a multidirectional sliding fit. The channel support plate 5 is provided to bear the main load of the upper channel 210 and transfer the load to the beam member 110, as well as to provide installation conditions for the first seismic isolation support 41.

[0093] The upper seat plate 411 and the lower seat plate 413 can be separate components, fixedly connected and installed at the bottom of the channel 210 and the top of the channel support plate 5. When the channel 210 is composed of thin-walled prestressed reinforced concrete channel sections or chemically-material channel sections, the upper seat plate 411 can be an embedded part, embedded in the bottom of the channel 210. Correspondingly, the lower seat plate 413 can also be embedded in the channel support plate 5.

[0094] When the channel 210 is composed of steel channel sections, the upper seat plate 411 can be directly pre-set at the bottom of the channel 210, and an arc-shaped corrugated groove 6 corresponding to the lower seat plate 413 is provided at the bottom of the channel 210; furthermore, when the channel 210 is a channel 210 in the form of corrugated steel plate, the bottom corrugation can be set to match the groove of the arc-shaped corrugated groove 6 of the lower seat plate 413, and can be directly used as the upper seat plate 411.

[0095] The upper seat plate 411, lower seat plate 413, and crown 412 are preferably made of chromium-containing stainless steel, and their chemical composition and mechanical properties should comply with the requirements of GB / T 3280; or the interface of ordinary steel plates can be treated with electroplated hard chrome to meet the requirements of hardness, strength, and wear resistance. The part of the arc-shaped corrugated groove 6 of the upper seat plate 411 and the lower seat plate 413 that abuts against the surface of the crown 412 (i.e., the abutting friction surface) is made of a material with a low coefficient of friction such as polytetrafluoroethylene or is coated with polytetrafluoroethylene.

[0096] like Figure 1 and Figure 4As shown, the second seismic isolation bearing 42 is a helical spring bearing, installed horizontally along the cross-section of the channel 210. One end is connected to the side wall of the channel 210, and the other end extends horizontally to connect to the secondary column 122 of the column member 120 or the side wall 32 of the pool. The second seismic isolation bearing 42 is installed on both sides of the channel 210. Its main spring is normally in a natural horizontal state, and there will be no failure of seismic isolation capacity due to long-term tension and compression under vertical conditions. When an earthquake occurs, the helical spring bearing restricts the displacement of the channel 210 in both lateral directions and dissipates seismic energy through cyclic deformation.

[0097] In one embodiment, a plurality of baffles (not shown in the figure) are also provided along the length of the channel 210. Each baffle is arranged along the cross-sectional direction of the channel 210. The connection position of the second seismic isolation bearing 42 to the outer wall of the channel 210 corresponds to the connection position of the baffle to the inner wall of the channel 210, that is, the baffle and the second seismic isolation bearing 42 are located in the same cross-section. The plurality of baffles are arranged along the length of the channel 210 to reduce the inrush flow and disperse the seismic force; at the same time, they provide lateral support for the channel 210. The baffles are arranged correspondingly to the second seismic isolation bearing 42, which further enhances the structural stability of the channel 210, making the channel 210 less prone to large deformation under the tension and compression of the second seismic isolation bearing 42 on both sides.

[0098] like Figure 1 and Figure 4 As shown, the third seismic isolation bearing 43 is a buckling-restrained brace. This buckling-restrained brace is positioned obliquely upwards along the cross-section of the channel 210, with one end connected to the upper sidewall of the channel 210 and the other end connected to the top beam 31. The buckling-restrained brace consists of a core steel brace and restraint units, restricting the vertical displacement of the channel 210 and absorbing and dissipating seismic energy. The buckling-restrained braces are typically arranged symmetrically on both sides. The lower ends of the two buckling-restrained braces are connected to the upper sides of the channel 210, and the upper ends extend obliquely upwards and outwards to connect with the top beam 31. The two buckling-restrained braces are arranged in an inverted V-shape.

[0099] In one embodiment, an X-shaped scissor brace 211 is also provided in the upper part of the channel 210. The scissor brace 211 is hinged in the middle, with its lower two ends connected to the inner side of the channel 210 at the corresponding position of the second seismic isolation bearing 42, and its upper two ends connected to the inner side of the channel 210 at the corresponding position of the third seismic isolation bearing 43. The X-shaped scissor brace 211, together with the second seismic isolation bearing 42 and the third seismic isolation bearing 43, forms a complete structural stiffness system in this cross-section, which can effectively prevent damage to the channel 210 in this part under seismic conditions and ensure the working performance of each seismic isolation bearing.

[0100] In summary, the channel system of this embodiment, through the coordinated arrangement of the frame support module 100, lightweight channel module 200, channel bearing plate 5, and seismic isolation module, has a main force transmission path of "channel load - channel bearing plate - secondary beam - main beam - column component or / and pool sidewall - bottom plate," resulting in a clear force transmission path and a reasonable structural pattern. The seismic isolation module, located between the frame support module 100 and the lightweight channel module 200, absorbs and dissipates the energy in the three-phase vector direction of an earthquake through a combination of "sliding friction bearing + helical spring bearing + buckling restraint bearing," acting separately and coupled. This reduces the seismic force transmitted from the frame support module 100 to the channel 210 and eliminates the amplification factor of the structural dynamic response of the channel 210 to the frame support module 100 during an earthquake, thereby reducing the seismic effect of the channel system and making it more conducive to achieving the seismic fortification target.

[0101] Example 3

[0102] like Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment of the sunken water plant channel system, a drainage opening 220 is provided on the side wall of the channel 210. The drainage opening 220 is preferably located on the end side along the length of the channel 210, and a quick-opening gate 221 controlled by an electronic control device is installed on the drainage opening 220. An external pipe is connected to the lower water tank, storage tank, or sump pit to quickly guide the water in the channel 210 to the corresponding location for collection, preventing water overflow from affecting maintenance access, equipment below, etc.

[0103] The channel 210 is equipped with a quick-closing gate 231 controlled by an electronic control device at the inlet 230. The channel system also includes a controller, to which both the quick-opening gate 221 and the quick-closing gate 231 are electrically connected, and the opening and closing of the quick-opening gate 221 and the quick-closing gate 231 are correlated.

[0104] The quick-opening gate 221 and the quick-closing gate 231 can be electrically controlled or manually controlled. In the event of a power outage or other accident, they can be opened or closed manually.

[0105] The quick-opening gate 221 and quick-closing gate 231 are used to quickly intercept and discharge water in the channel 210 before or during an earthquake, thereby changing the water-filled state of the channel 210, improving the load conditions of the channel 210 and the frame support module 100 during an earthquake, and reducing the risk of damage to the channel 210 and the frame support module 100. The quick-closing channel interception also prevents water in the pool from continuously overflowing through the damaged section of the channel to the maintenance passage and equipment area below the second basement level. The quick-opening gate 221 and quick-closing gate 231 can also be used for routine installation, dismantling, and maintenance of the channel, making construction convenient and safe.

[0106] Example 4

[0107] like Figure 10 As shown, the submerged water plant channel system of this embodiment has an overflow port 240 on the end side wall and / or top plate of the channel 210. The overflow port 240 is positioned higher than the normal water level, and a flip-up movable cover plate 241 is installed on the overflow port 240.

[0108] During an earthquake, the water flow within channel 210 accumulates along its long path, creating a concentrated surge at the end that impacts the end structure, potentially causing localized structural damage. By installing an overflow outlet 240 and a movable cover 241 at the end, when an earthquake occurs and the water surge at the end of channel 210 is large, with the hydraulic head far exceeding the channel top elevation, the impacting water flow can force open the movable cover 241 of the overflow outlet 240, directing the water flow outside channel 210. This effectively reduces the impact of violent water flow fluctuations on channel 210 during an earthquake. The outflow of water from the channel also carries away seismic energy, reducing the internal load and complex solid-liquid coupling effects within channel 210, thereby minimizing the damage caused by seismic energy to the channel system.

[0109] Example 5

[0110] This embodiment provides a seismic control method for a channel system. This method is applicable to the sunken water plant channel system described in embodiments 1 to 4 above, and is used to control the channel system's response to earthquakes.

[0111] The channel system includes a controller, a quick-opening gate 221 located at the drainage opening 220 on the side wall of the channel 210, and a quick-closing gate 231 located at the water inlet of the channel 210. The controller of the channel system is connected to an earthquake early warning system, which is existing technology and will not be described in detail here.

[0112] like Figure 11 As shown, the seismic control method for this channel system includes the following steps:

[0113] Step S1: The controller receives earthquake early warning information from the earthquake early warning system via wired and / or wireless means;

[0114] Step S2: When no earthquake occurs, that is, when the controller does not receive earthquake early warning information, the channel operates normally, the quick-closing gate 231 at the inlet 230 of the channel 210 is normally open, and the quick-closing gate 231 at the drainage outlet 220 of the channel 210 is normally closed.

[0115] Step S3: When an earthquake occurs in a certain area, the earthquake early warning system issues an earthquake early warning message. When the controller receives the earthquake early warning message, the controller determines whether to perform an adjustment action based on the earthquake early warning message. If the determination result is yes, proceed to step S31; if the determination result is no, proceed to step S32.

[0116] Step S31: When the determination result is yes, the controller sends an action signal to the electronic control device to control the quick-closing gate 231 at the inlet 230 of the channel 210 in the lightweight channel module 200 to close quickly, and at the same time control the quick-opening gate 221 at the drainage hole 220 of the channel 210 in the lightweight channel module 200 to open, so as to intercept the water flow entering the channel 210 and quickly discharge the water stagnant in the channel 210.

[0117] In step S32, when the determination result is negative, the channel system still operates normally, the quick-closing gate 231 at the inlet 230 of channel 210 is normally open, and the quick-closing gate 231 at the drainage outlet 220 of channel 210 is normally closed.

[0118] In step S3, when the controller receives earthquake early warning information, the controller determines whether to perform adjustment actions based on the earthquake early warning information, including:

[0119] When the controller receives an earthquake early warning message, it analyzes the content of the message to determine the earthquake early warning level. The message includes the earthquake's occurrence time, location, source type, magnitude, depth, and estimated arrival time. The determined earthquake early warning level is compared with a preset threshold in the controller, and the controller determines whether to perform an adjustment action based on the comparison.

[0120] The seismic control method of this channel system can take emergency measures in advance based on earthquake early warning information, drain the channel water, reduce or avoid complex "solid-liquid" model seismic response, and minimize the damage caused by earthquakes.
