Description

Technical Field

[0001] This invention belongs to the field of channel design technology, and specifically relates to a water plant channel system. Background Technology

[0002] Channels are an important component of water plants, connecting different treatment units or located within some treatment units. They are used to transport water media, and equipment and instruments are installed inside the channels to treat and monitor water quality. The proper functioning of the channels directly affects the operation of the water plant.

[0003] Conventional channels are made of reinforced concrete, with a rectangular cross-section and a wall thickness of 200-300mm. Channels are typically mounted sideways on top of the pool wall; some are located inside the pool, others outside, and still others suspended from the top beams. The reinforced concrete channels, surrounding pool walls, and top beams form a monolithic structure. Their seismic calculation models are often unclear, making them weak points in the water plant's structural system during earthquakes, prone to structural damage, and resulting in lengthy and costly repairs and renovations. Ancillary equipment such as screens, UV filters, and gates need to be installed within the channels. Conventional reinforced concrete channels have numerous pre-installed and embedded features, resulting in complex local structural designs and challenging in-situ casting. Furthermore, secondary casting is often required internally, making formwork construction difficult, slowing progress, and leading to poor quality.

[0004] Because existing reinforced concrete channels have various problems in construction, operation and later renovation, and the existing channels have not yet formed a mature and reasonable seismic standard and structural system, it is urgent to improve the existing reinforced concrete channel system. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this invention provides a water plant channel system. The support modules of this system retain the load-bearing and seismic-resistant main structure, while removing the channel wall panels to reduce self-weight and achieve better seismic fortification. The channel modules utilize lightweight, thin-walled channels that can be detachably installed on the support modules, resulting in a clear force transmission path and a reliable structure. The resulting channel system exhibits good seismic performance, saves materials and costs, and can be manufactured in a factory and installed on-site. This facilitates installation and dismantling, saves construction time, and provides good equipment compatibility. It also minimizes construction space constraints, making it more convenient and safer.

[0006] The technical solution adopted in this invention is as follows:

[0007] A water plant channel system includes a support module and a channel module;

[0008] The support module includes:

[0009] Several main beams, each of which is connected to the side wall of the pool at one end and extends horizontally outward at the other end, and the main beams are arranged in parallel at intervals.

[0010] Several columns, the lower end of which is connected to one end of the main beam extending outward, and the upper end of which is connected to the top beam slab. The columns and the main beam correspond one-to-one to form a single frame.

[0011] The secondary beam is horizontally and continuously installed at one end of the main beam that extends outward, and is perpendicular to the main beam.

[0012] The cantilever is horizontally and continuously installed on the side wall of the pool, and the main beam is located at the root of the side wall of the pool.

[0013] The channel module is a lightweight, thin-walled channel that is detachably installed on the main beam, secondary beam, and cantilever, and is located within the single frame.

[0014] In one embodiment of this application, the channel module includes a standard section and an end section. The standard section includes a channel body formed by flat sheet metal, and the end section includes a channel body formed by corrugated sheet metal.

[0015] In one embodiment of this application, the end cap of the end section of the channel module is provided with a drainage hole, and the drainage hole is equipped with a pressure relief plate that can be detached under stress.

[0016] or,

[0017] The end sealing plate and / or top wall of the end section of the channel module are provided with an overflow port, which is set above the normal water level and is equipped with a flip-up movable cover.

[0018] In one embodiment of this application, the end cap is provided with a reinforcing structure around the discharge opening;

[0019] And / or, the pressure relief plate is a brittle component with high stiffness but low strength;

[0020] And / or, a number of rigid rods are provided on the outer side of the pressure relief plate, one end of the rigid rod is connected to the pressure relief plate, and the other end is connected to the support module, the side wall of the pool, or the top beam.

[0021] In one embodiment of this application, a seismic support is also included. The seismic support is located at a standard section of the channel module and installed on the secondary beam and the cantilever, with its upper side abutting against the bottom of the channel module.

[0022] In one embodiment of this application, the seismic support is a composite rubber support.

[0023] In one embodiment of this application, the secondary beam and the cantilever are provided with sliding structural surfaces at locations corresponding to the end section of the channel module, and the sliding structural surfaces slide against the bottom of the end section of the channel module.

[0024] In one embodiment of this application, the channel module is provided with a plurality of water-blocking components along its length, the water-blocking components being either high-level wave-breaking plates or low-level water-blocking plates;

[0025] The high-level breakwater is fixedly installed in the upper part of the channel. If the bottom of the high-level breakwater is slightly lower than the normal water level, the high-level breakwater is provided with ventilation holes; if the bottom of the high-level breakwater is higher than the normal water level, no ventilation holes are provided.

[0026] The low-position baffle includes a connecting shaft, an upper baffle fixedly disposed on the upper part of the connecting shaft, and a lower baffle fixedly disposed on the lower part of the connecting shaft. The upper baffle and the lower baffle are perpendicular to each other. The connecting shaft is rotatably mounted on the inner wall of the channel. At the normal water level, the lower baffle is located in the water flow and is in the same direction as the water flow. The upper baffle is slightly higher than the normal water level and is perpendicular to the length of the channel. When the water flow fluctuates, it impacts the upper baffle, which causes the connecting shaft to rotate 90° and then lock.

[0027] In one embodiment of this application, an anti-seismic water-blocking component is further included. The anti-seismic water-blocking component includes a sensor, a controller, and a water-blocking airbag. The water-blocking airbag is installed at the water inlet of the channel module, and the sensor is installed at the channel body formed by corrugated plates in the end section. The sensor, controller, and water-blocking airbag are electrically connected.

[0028] In one embodiment of this application, the support module is a reinforced concrete component;

[0029] The channel module is a prefabricated thin-walled prestressed reinforced concrete channel, a chemical material channel, a steel material channel, or a composite channel of steel and chemical materials.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. The water plant channel system of the present invention retains the main structure for load-bearing and seismic resistance in its support module, removes the channel wall panels, reduces the self-weight load, and can achieve better seismic fortification goals; the channel module adopts a lightweight thin-walled channel, which can be detachably installed on the support module, with a clear force transmission path and reliable structural form; the resulting channel system has good seismic performance, saves materials and costs, can adopt a factory production and on-site installation scheme, is convenient to install and dismantle, saves construction time, and has good equipment and instrument compatibility, with less restricted construction space, making it more convenient and safer.

[0032] 2. Seismic bearings are installed below the standard sections (the main part along the channel length) of the channel module, and matching sliding structural surfaces are installed below the end sections. The seismic bearings effectively buffer and isolate the vibration transmission between the channel module and the support module. The end sections of the channel module are enclosed by corrugated plates, which, in conjunction with the sliding structural surfaces, can adapt to the large relative displacements generated by earthquakes. Through reciprocating tensile and compressive deformation and sliding friction, the seismic energy is dissipated. In conjunction with the sliding structural surfaces, the relative displacement can be amplified during an earthquake, better triggering the failure mechanism of the end pressure relief plate and the working mechanism of the water-blocking airbag. Unlike the traditional seismic resistance approach of "strengthening and protecting the structural system," this application adopts the approach of "guiding the directional failure of the structure" in the local structure at the ends. This transforms the disorderly damage of the channel module caused by earthquakes into a directional damage form with controllable impact and rapid repair. The pressure relief structure further dissipates the seismic energy while improving working conditions, achieving the seismic resistance goal of protecting the main structure of the channel system.

[0033] 3. Based on the channel liquid level and other conditions, corresponding water-blocking components are installed inside to reduce the sloshing and fluctuation of the liquid level in the channel, disperse the impact effect of the surge on the channel, avoid the accumulation of water flow and water pressure along the length of the channel module and thus prevent damage to the channel, and increase the safety of the channel system.

[0034] 4. Install earthquake-resistant water-blocking components. By monitoring the displacement and deformation of the end section of the channel to determine the earthquake signal, the water-blocking airbags are automatically activated to intercept the water ingress, preventing the channel module from continuously taking in water during an earthquake and improving the stress model of the channel system under earthquake conditions.

[0058] 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.

[0059] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0060] Example 1

[0061] This invention provides a water plant channel system, which is installed on the top of the pool in a water plant or sewage treatment plant, and includes mutually separate support modules 100 and channel modules 200, etc.

[0062] like Figures 1 to 5As shown, the support module 100 is a reinforced concrete component, including several main beams 110, several columns 120, secondary beams 130, and cantilevered eaves 140 (i.e., corbels).

[0063] Several main beams 110 are horizontally arranged, with one end vertically connected to the pool side wall 32 and anchored to the pool side wall 32 by steel bars, and the other end extending horizontally outward; several main beams 110 are arranged in parallel at intervals in the same horizontal plane.

[0064] Several columns 120 are vertically arranged, with their lower ends connected to the outwardly extending end of the main beam 110 and their upper ends connected to the top beam 31. The columns 120 and the main beam 110 are connected one-to-one to form a single frame. Preferably, the columns 120 are anchored to the beam members of the top beam 31, and the main beam 110 and the beam members of the top beam 31 are parallel and corresponding.

[0065] The secondary beam 130 is typically horizontally located at one end of the main beam 110 extending outwards, along the length of the channel, and is perpendicularly connected to the main beam 110 and the column 120. The secondary beam 130 may include multiple parallel beams, which, in addition to being located at the end of the main beam 110 extending outwards, may also be perpendicularly connected to the middle area of ​​the main beam 110.

[0066] The cantilever 140, also known as the corbel, is horizontally and continuously installed on the pool side wall 32 and is vertically connected to the root of the pool side wall 32 at the connection point with the main beam 110.

[0067] The channel module 200 is a lightweight, thin-walled channel that can be detachably installed on the main beam 110, the secondary beam 130, and the cantilever 140. That is, the main beam 110, the secondary beam 130, and the cantilever 140 form the bottom bearing plane of the support module 100. The channel module 200 is installed on this bearing plane and is located within a single frame formed by the column 120 and the main beam 110.

[0068] In summary, the support module 100 of this application has a frame structure, set on the pool side wall 32 and the top beam 31. Its main beam 110 and columns 120 form several single frames. The horizontal secondary beams 130 and the cantilever 140 are supported by the horizontal main beams 110 and the pool side wall, respectively, and are arranged along the bottom of the channel to form a channel support. The single frames and the vertical secondary beams 130 and cantilever 140 form an integral reinforced concrete frame support module system. The structure is simple and the stress is reasonable. The support module 100 retains the main structure for load bearing and seismic resistance, and removes the channel wall panels to reduce the self-weight load, thereby achieving better seismic fortification goals. The channel module 200 adopts a lightweight thin-walled channel, which can be detachably installed on the support module 100. The force transmission path is clear and the structure is reliable. The resulting channel system has good seismic performance, saves materials and costs, can be manufactured in the factory and installed on site, is easy to install and dismantle, saves construction time, has good equipment and instrument compatibility, has less restricted construction space, and is more convenient and safe.

[0069] Example 2

[0070] Based on Example 1, the channel module 200 in this example is a prefabricated structure, adopting a modular approach. It is manufactured in the factory and then transported to the site for installation. The lightweight, thin-walled channel of the channel module 200 can be a prefabricated thin-walled prestressed reinforced concrete channel, a chemical material channel, a steel channel, or a composite channel of steel and chemical materials. The joints of the channel module 200 can be connected using socket joints, flange connections, welding, etc., to adapt to different connection requirements and usage scenarios. A water-stop structure should be provided at the joints. When the channel module 200 is a steel channel, an inner lining layer is made on the inside. The inner lining layer can be made of organic or inorganic anti-corrosion materials, bonded or coated onto the steel channel to form a composite structure.

[0071] The channel module 200 has a rectangular or near-rectangular cross-section. Along its length, it can be divided into standard sections 210 and end sections 220. Standard sections 210 form the main body of the channel module along its length, while end sections 220 are located at the inlet and outlet ends and at bends. The channel module 200 is assembled from several standard sections 210 and end sections 220. Standard sections 210 include a channel body enclosed by flat plates, and end sections 220 include a channel body enclosed by corrugated plates. Alternatively, standard sections 210 can also have corrugated sections formed by intermittently arranged flat plate sections. These corrugated sections have elastic deformation capabilities, allowing them to reciprocate and adapt to displacement deformation caused by earthquakes, absorbing concentrated stress and reducing the seismic effect of the channel module 200. Preferably, the channel module 200 is a prefabricated steel channel, where the flat plates are flat steel plates and the corrugated plates are corrugated steel plates.

[0072] The corrugated plate at the end section 220 forms the main body of the channel, which can well adapt to the large surge generated in the end of the channel under seismic conditions. Through the reciprocating tension and compression deformation of the corrugated section, the seismic energy is reduced and consumed, and the channel system is protected from damage to a certain extent.

[0073] Example 3

[0074] Based on Example 2, such as Figure 1As shown, in this embodiment, a discharge port 222 is provided on the end sealing plate 221 of the end section 220 of the channel module 200. A pressure relief plate 223 that can be detached under stress is sealed and installed on the discharge port 222. Under seismic conditions, the surge at the end of the channel module 200 will form a large impact flow, which may cause local damage to the channel. The pressure relief plate 223 can be directionally damaged under the action of a large surge, changing the disordered damage form with uncertain position and form in the channel module into a directional damage form. The damage to the pressure relief plate 223 will consume seismic energy, allowing the water in the channel to be discharged through the discharge port 222 and carry away the seismic energy, and reducing the internal water load. This fundamentally changes the load conditions and seismic response of the channel module, changing it from the original complex "solid-liquid" coupling form to a conventional steel channel solid form, greatly reducing the uncertain damage risk of the channel module 200 and its internal equipment.

[0075] Preferably, the end sealing plate 221 is provided with a reinforcing structure around the discharge opening 222, such as reinforcing ribs, to improve the load-bearing capacity around the discharge opening 222 and resist greater impact forces.

[0076] The pressure relief plate 223 is a brittle component with high rigidity but low strength, such as one made of materials like plastic steel, ceramic, cast iron, or glass. It can withstand normal water pressure under normal conditions, but is prone to breakage under impact deformation during large earthquakes. Furthermore, the pressure relief plate 223 is designed as a detachable structure, making it easy to disassemble in case of damage and convenient to install and remove.

[0077] like Figure 1 and Figure 3 As shown, in one embodiment, a plurality of rigid rods 4 are also provided on the outer side of the pressure relief plate 223. One end of the rigid rod 4 is connected to the unfavorable stress position on the outer side of the pressure relief plate 223, and the other end extends obliquely along the length of the channel and is connected to the column 120 of the support module 100, the pool sidewall 32, or the top beam 31, abutting against the outer side of the pressure relief plate 223. During an earthquake, the corrugated plate portion of the channel module in the end section 220 undergoes reciprocating deformation, resulting in relative displacement with the support module 100, the pool sidewall 32, and the top beam 31. This causes the rigid rods 4 to abut against the end of the pressure relief plate 223, generating concentrated stress. When the earthquake exceeds a certain intensity, the pressure relief plate 223 is preferentially damaged due to the interaction between the deformation of the corrugated plate in the end section 220 and the rigid rods 4, resulting in directional discharge. Targeted damage can prevent secondary disasters caused by uncontrollable channel breakage locations and leaks above precision equipment and other facilities. Furthermore, a guide channel should be installed below the spillway opening 222 in the external channel to guide the spilled water to the collection pit or storage tank below. The pressure relief plate 223 can be quickly replaced after an earthquake to restore water supply operation.

[0078] Example 4

[0079] Based on Example 2, such as Figure 9 As shown, in this embodiment, the end sealing plate 221 and / or the top wall of the end section 220 of the channel module 200 are provided with an overflow port 224. The overflow port 224 located on the end sealing plate 221 should be set higher than the normal water level. A flip-up movable cover plate 225 is installed on the overflow port 224.

[0080] During an earthquake, when the flow at the end of channel module 200 is large and the hydraulic head far exceeds the channel top elevation, the impact water flow can force open the end sealing plate 221 and the movable cover plate 225 of the overflow port 224 on the top wall, directing the water flow outside the channel module 200. This reduces the impact of violent water fluctuations inside the channel on the channel module during an earthquake. The outflow of water can carry away seismic energy, reducing the internal load and complex coupling effects of the channel, and to a certain extent lowering the probability of earthquake damage to the channel system.

[0081] Example 5

[0082] Based on embodiments 2, 3, or 4, this embodiment further includes a seismic support 5, which is located below the standard section 210 of the channel module 200 and corresponds to the channel body formed by the planar panels. The seismic support 5 is arranged along the length of the channel and installed on the secondary beam 130 and the cantilever 140, with its upper side abutting against the bottom of the channel body formed by the planar panels of the standard section 210 of the channel module 200.

[0083] Optionally, the seismic bearing 5 is a composite rubber bearing, which can be composed of multiple layers of rubber and steel plates stacked alternately, with a single layer thickness of 2~5mm; of course, the seismic bearing 5 can also be other forms of composite rubber bearing. Furthermore, limiting components matching the seismic bearing 5, such as angle steel and soft pads, can be installed below the standard section 210 to prevent large relative displacement between the channel module 200 and the support module 100 under rare earthquake conditions.

[0084] The secondary beam 130 and the cantilever 140 are provided with a sliding structural surface 6 at the corresponding position of the end section 220 of the channel module 200. The sliding structural surface 6 can be a smooth steel plate groove embedded part, corresponding to the corrugated part of the end section 220. The sliding structural surface 6 slides and abuts against the bottom of the corrugated part of the end section 220. The contact interface is coated with a lubricating material, such as silicone grease, to play a lubricating role.

[0085] The reinforced concrete support module 100 is a rigid structure with strong load-bearing and seismic resistance, while the steel channel module 200 is a flexible structure with strong adaptability to deformation and energy dissipation. Seismic bearings 5 ​​connect the two. Under normal operating conditions, the seismic bearings 5 ​​add a buffer layer to the contact surface between the channel module 200 and the support module 100, avoiding rigid contact and improving the interface stress conditions. Under seismic conditions, the structural response is concentrated at the seismic bearings 5, blocking and weakening the transmission of seismic energy, causing the channel to change from violent swaying to slow translational motion. The sliding structural surface 6, in conjunction with the corrugated structure of the elastically deformable end section 220, amplifies the relative displacement of the end during an earthquake. Combined with the pressure relief plate 223 and the rigid rod 4, it can better trigger the directional failure of the pressure relief plate 223, realizing the mechanism of "guiding structural directional failure".

[0086] Example 6

[0087] Based on embodiments 1-5, this embodiment provides several water-retaining components spaced along the length of the channel module 200. The type of water-retaining component is determined according to the height of the normal operating water level of the channel module. For higher normal water levels, the water-retaining component in the channel module 200 is a high-level wave-breaking plate 71; for lower normal water levels, the water-retaining component is a low-level water-retaining plate 72. Providing different types of water-retaining components for the channel module 200 at different normal water levels can better reduce water flow surging within the channel and disperse dynamic water pressure within the channel.

[0088] like Figure 7 As shown, the high-level breakwater 71 is a fixed type, horizontally fixedly installed in the upper part of the channel section. It includes two forms: one where the bottom of the high-level breakwater 71 is slightly lower than the normal water level, i.e., the bottom is submerged in water, and this type of high-level breakwater 71 has several ventilation holes 711 on the plate above the normal water level (no ventilation holes are provided for channels with top openings); the other form is where the bottom of the high-level breakwater 71 is not submerged in water, which is a non-submerged high-level breakwater 71, and no ventilation holes are provided on the plate. The two types of high-level breakwater 71 are used in combination. Submerged high-level breakwaters are installed at the initial position of liquid level fluctuations within the channel module, while non-submerged high-level breakwaters are installed at the position where liquid level fluctuations develop. This effectively reduces water flow surging within the channel and disperses dynamic water pressure within the channel.

[0089] like Figure 8As shown, the low-level baffle 72 is movable and includes a connecting shaft 721, an upper baffle 722, and a lower baffle 723. The upper baffle 722 is fixed to the upper part of the connecting shaft 721 from one side, and the lower baffle 723 is fixed to the lower part of the connecting shaft 721 from one side. The upper baffle 722 and the lower baffle 723 are perpendicular to each other. The connecting shaft 721, the upper baffle 722, and the lower baffle 723 are fixed as a single unit. At the normal water level, the connecting shaft 721 is vertically limited and rotated on the inner wall of the channel. The lower baffle 723 is located in the water flow and is aligned with the water flow direction (i.e., aligned with the length direction of the channel). The upper baffle 722 is slightly higher than the normal water level and perpendicular to the length direction of the channel. When the water flow fluctuates significantly during an earthquake, the surging water impacts the upper baffle 722, causing the lower baffle 72 to rotate as a whole. After the connecting shaft 721 rotates 90°, it locks. When locked, the lower baffle 723, perpendicular to the channel length, intercepts the surging water flow, disperses the impact, and reduces excessive accumulation of impact water along the channel length. The connecting shaft 721, after rotating 90°, can be locked using limiting structures such as pins and grooves, ensuring that the rotational displacement is irreversible.

[0090] Example 7

[0091] like Figure 3 , Figure 6 and Figure 10 As shown, the water plant channel system in this embodiment also includes an anti-seismic water-blocking component, which includes a sensor 232, a controller, and a water-blocking airbag 231. The water-blocking airbag 231 is installed at the water inlet 230 of the channel module 200, and the sensor 232 is installed at the middle section 220 of the channel module 200, where the channel body is formed by corrugated sheets. The sensor, controller, and water-blocking airbag 231 are electrically connected.

[0092] When an earthquake occurs, characteristic earthquake signals (such as displacement, velocity, and seismic wave patterns) are monitored by sensors and transmitted to the controller. The controller analyzes and determines whether it is an earthquake and whether the earthquake has reached a preset seismic intensity. If it is determined to be an earthquake and the preset seismic intensity has been reached, an action signal is sent to the water-blocking airbag 231, triggering the airbag 231 to inflate and block the water inlet 230, thus preventing continuous water intake into the channel module 200 and continuous overflow at the damaged point. The preset seismic intensity in the controller may include characteristic signal values ​​of seismic waves such as displacement, velocity, and acceleration.

[0093] The seismic blocking component is installed in conjunction with the end section 220, pressure relief plate 223 and overflow port 224. When an earthquake occurs, it locally amplifies the seismic response (such as displacement and deformation), consumes seismic energy, and triggers the working mechanism of pressure relief plate 223 and water blocking airbag 231. This improves the load and seismic resistance of the channel system, reduces the damage of earthquakes to the channel system, and enhances the seismic resistance of the channel system.
