Description

Technical Field

[0001] This utility model belongs to the field of road and bridge construction technology, specifically relating to a water bag pre-pressurization device for cantilever cast-in-place hanging basket structure. Background Technology

[0002] In the field of road and bridge construction, cantilever cast-in-place formwork is the core equipment for the construction of long-span continuous beam bridges and rigid frame bridges. Water bag preloading is a key verification step before the formwork is put into use. By filling the water bag with water to simulate the load of subsequent concrete pouring, the load-bearing strength of the formwork is verified, and its deformation data is measured. This provides a basis for setting the pre-camber of the beam construction, which is directly related to the accuracy and safety of bridge construction.

[0003] Currently, the mainstream cantilever cast-in-place hanging basket structure water bag preloading device generally adopts a single water bag independent drainage design during the drainage stage, that is, each water bag is connected to the drainage system through an independent pipe. However, this mode has significant technical pain points in practical applications and is difficult to meet construction requirements.

[0004] First, the inherent differences in the characteristics of water bags lead to uneven drainage conditions. Water bags are mostly made of flexible composite materials, and slight deviations can easily occur in material thickness, elasticity coefficient, and volume during the production process. Furthermore, during hoisting, the flatness of the support points of the basket frame and the tension of the hoisting ropes affect the unfolding shape and internal water flow channel state of each water bag, resulting in inherent differences in the drainage conditions of each water bag even if the initial water level is the same.

[0005] Secondly, differences in pipeline system parameters further exacerbate drainage imbalance. The pipes connecting each water bag often vary in diameter, length, and number of bends due to differences in procurement batches, construction cutting and laying errors, resulting in significant differences in friction resistance and local resistance. At the same time, differences in the sealing of pipe joints and the smoothness of the inner wall further amplify the deviation in drainage resistance, exacerbating the problem of inconsistent drainage speeds among the water bags.

[0006] Finally, uneven drainage rates cause fluctuations in the stress on the formwork, threatening construction safety and precision. Some water bags are emptied rapidly, resulting in a sudden reduction in load, while others remain under high water levels and high loads. This causes abrupt changes in the load distribution of the formwork, leading to instantaneous stress concentration in the load-bearing system. This can easily cause fatigue damage to components, weld cracking, and other safety hazards. Simultaneously, uneven loads disrupt the deformation pattern of the formwork determined by preloading, resulting in elevation deviations and linear distortions during subsequent beam pouring, affecting construction quality.

[0007] In summary, the existing water bag preloading device for cantilever cast-in-place hanging basket structures urgently needs optimization to achieve uniform drainage from each water bag, ensuring the safety of hanging basket construction and the accuracy of bridge construction. Utility Model Content

[0008] The purpose of this invention is to provide a water bag pre-pressurization device for cantilever cast-in-place hanging basket structures to solve the problems existing in the background art.

[0009] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: The water bag preloading device for the cantilever cast-in-place hanging basket structure includes: Basket rack; Multiple water bags are evenly suspended on the bottom basket frame, and the horizontal height of each water bag is consistent. A transfer water storage tank is suspended on the base frame, and the highest point of the horizontal height of the transfer water storage tank is higher than the highest point of the horizontal height of the water bag, while the lowest point of the horizontal height of the transfer water storage tank is lower than the lowest point of the horizontal height of the water bag. The main pipe is fixedly suspended on the bottom basket frame, and the horizontal height of the main pipe is lower than the horizontal height of the water bag. One end of the main pipe is connected to the transfer water storage tank. Multiple branch pipes are connected between each of the water bags and the main pipe; The drain pipe is connected to the intermediate water storage tank.

[0010] Optionally, a first solenoid valve is connected to the bottom of the water bag, and the branch pipe is connected to the water bag through the first solenoid valve.

[0011] Optionally, a second solenoid valve is provided between the main pipe and the intermediate water storage tank, and a water injection pipe is connected to the end of the main pipe away from the second solenoid valve.

[0012] Optionally, the transfer water tank has a plurality of first vent holes on its top circumference, and the water bag has a second vent hole on its top.

[0013] Optionally, a dust cover is provided on the second vent.

[0014] Optionally, the drain pipe is connected to the lower side of the intermediate water storage tank, and the horizontal height of the connection between the drain pipe and the intermediate water storage tank is lower than the horizontal height of the connection between the main pipe and the intermediate water storage tank.

[0015] Optionally, the lower end of the transfer water tank is open, and the lower end opening of the transfer water tank is threadedly sealed with a cleaning cover.

[0016] The beneficial effects of this utility model are: By setting up a transfer water storage tank, uneven drainage caused by differences in water bags and pipes is eliminated, sudden changes in the load on the hanging basket are avoided, safety hazards are reduced, and construction safety is ensured. The water bags are level and the drainage is thorough, reducing interference with preloading data, ensuring accurate deformation patterns of the hanging basket, providing a reliable basis for beam construction, and improving bridge quality. The design of solenoid valves and water injection pipes simplifies filling and drainage operations, and the cleaning cover and dust cover facilitate maintenance, improving construction efficiency. Gravity-based drainage requires no additional power, and easy-to-maintain components reduce energy consumption and later operating costs. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] like Figure 1-4 As shown, the water bag preloading device for the cantilever cast-in-place hanging basket structure includes: Basket frame 101; Multiple water bags 102 are evenly suspended on the bottom basket frame 101, and the horizontal height of each water bag 102 is the same; The intermediate water storage tank 103 is hoisted on the bottom basket frame 101, and the highest point of the horizontal height of the intermediate water storage tank 103 is higher than the highest point of the horizontal height of the water bag 102, while the lowest point of the horizontal height of the intermediate water storage tank 103 is lower than the lowest point of the horizontal height of the water bag 102. The main pipe 104 is fixedly suspended on the bottom basket frame 101, and the horizontal height of the main pipe 104 is lower than the horizontal height of the water bag 102. One end of the main pipe 104 is connected to the intermediate water storage tank 103. Multiple branch pipes 105 are respectively connected between each water bag 102 and the main pipe 104; Drainage pipe 106 is connected to intermediate water storage tank 103.

[0023] The base frame 101, as the basic load-bearing component of the device, is the lower part of the entire cantilever cast-in-place basket. It is used to fix and install the water bags 102, the intermediate water storage tank 103, and the main pipe 104. At the same time, it evenly transfers the load of each component to the basket's load-bearing system. Through its own rigidity and the preset hoisting points and fixing holes, it provides support for the precise positioning and installation of other components, preventing displacement of components due to misalignment or unstable support. This ensures the structural stability of the entire pre-compression device during the filling and drainage process, indirectly reducing drainage deviation caused by component shaking. It lays the foundation for the subsequent uniform horizontal height of each water bag 102 and the stable connection of the pipeline system.

[0024] Multiple water bags 102 are the core carriers of the preload. By filling them with water, they simulate the actual load of the concrete poured later in the hanging basket. During installation, they are evenly suspended on the bottom basket frame 101 and kept at a consistent horizontal height. This design ensures that the initial liquid level of each water bag 102 is uniform, providing a benchmark condition for achieving uniform drainage through the principle of communicating vessels. At the same time, the evenly distributed water bags 102 can evenly transfer the load to the bottom basket frame 101, avoiding local overload of the hanging basket and eliminating the difference in drainage speed caused by the initial water level difference, thus reducing the risk of load imbalance from the source.

[0025] The intermediate water storage tank 103, serving as the intermediate hub for drainage of the water bag 102, is suspended on the base frame 101. Its highest point is higher than the highest point of the water bag 102, and its lowest point is lower than the lowest point of the water bag 102. The high-position design can prevent water overflow when the water bag 102 is filled and buffer the pressure fluctuations in the initial stage of drainage. The low-position design ensures that the water in the water bag 102 can be completely discharged under the action of gravity. Through the intermediate function, the traditional independent drainage of a single water bag is transformed into a unified drainage mode of multiple water bags, eliminating the uneven drainage foundation conditions caused by the differences in the characteristics of each water bag 102, ensuring the thoroughness of drainage and the stability of the system, and reducing the impact of residual water on the pre-pressurization accuracy.

[0026] The main pipe 104 is fixedly suspended on the base frame 101, with a horizontal height lower than the water bags 102 and one end connected to the intermediate water storage tank 103. It serves as a water flow collection channel between each water bag 102 and the intermediate water storage tank 103. It uses the principle of gravity to allow the water in the water bags 102 to flow naturally to the main pipe 104, and then be uniformly transported to the intermediate water storage tank 103. The fixed installation design avoids the pipe from bending or displacement due to water flow impact or deformation of the water bags 102, ensuring the stability of the water flow channel cross section. The height design of being lower than the water bags 102 provides sufficient power for the water flow, reduces the difference in drainage speed caused by insufficient water pressure, and further improves the synchronicity of drainage of each water bag 102.

[0027] Multiple branch pipes 105 are connected between each water bag 102 and the main pipe 104, serving as a connecting bridge between the water bag 102 and the main pipe 104. This ensures precise connection between a single water bag 102 and the main pipe 104, guaranteeing that the water flow from each water bag 102 can flow into the main pipe 104 independently and stably. Through unified pipe parameters, the resistance of the water in each water bag 102 passing through the branch pipes 105 is consistent under the same water pressure, ensuring synchronized water flow speed. This eliminates the uneven drainage resistance caused by differences in pipe parameters in the traditional independent drainage mode, and avoids sudden changes in the hanging basket load caused by some water bags being emptied quickly and others having high water levels.

[0028] The drain pipe 106 is connected to the intermediate water storage tank 103. A valve is installed at the end of the drain pipe 106 to control the drainage of water collected in the intermediate water storage tank 103 to a designated area, thus completing the entire drainage process. Through the reasonable connection position design with the intermediate water storage tank 103, combined with the height characteristics of the intermediate water storage tank 103, it ensures that the water in the intermediate water storage tank 103 can be completely discharged under the action of gravity, avoiding water accumulation in the tank and causing drainage stagnation, ensuring the thoroughness of drainage of the entire system, reducing water residue, ensuring that the load of the hanging basket can be stably unloaded after the preloading is completed, and avoiding load deviation caused by residual water from affecting the accuracy of the preloading data.

[0029] Furthermore, in an optional embodiment, to prevent the drainage speed of the drain pipe 106 from being too fast or too slow and affecting the stability of the connection between the main pipe 104 and the intermediate water storage tank 103, the flow rate can be precisely controlled by means of "valve adjustment" or "pump assistance". The core objective is to match the drainage speed of the drain pipe 106 with the water delivery speed of the main pipe 104 to the intermediate water storage tank 103. The specific design is as follows: Install a shut-off valve or throttle valve on the drain pipe 106 to control the drainage flow rate by adjusting the valve opening: In the initial drainage stage, the valve opening can be appropriately reduced so that the flow rate of the drain pipe 106 is lower than the water delivery rate of the main pipe 104, allowing a small amount of water to accumulate in the intermediate water storage tank 103 to form a stable water level, avoiding a sudden drop in pressure in the intermediate water storage tank 103 due to instantaneous emptying, which could cause air to be drawn in when the main pipe 104 delivers water; After the water bag 102 continuously delivers water to the intermediate water storage tank 103, gradually increase the valve opening to make the flow rate of the drain pipe 106 and the water delivery rate of the main pipe 104 tend to be balanced (this can be monitored in real time by a flow meter to ensure that the flow rate difference is controlled within ±10%), which ensures both drainage efficiency and maintains a stable water level in the intermediate water storage tank 103, without disrupting the water delivery pattern between the main pipe 104 and the water bag 102.

[0030] If there are many water bags 102 and the total water delivery volume is large, a centrifugal pump (with variable frequency speed control) can be installed in the middle section of the drain pipe 106. The drainage flow rate can be controlled by adjusting the pump speed: when the water delivery speed of the main pipe 104 is fast, the pump speed is increased to increase the flow rate of the drain pipe 106; when the water delivery speed of the main pipe 104 slows down (such as when the water level of the water bags 102 drops), the pump speed is reduced to decrease the flow rate of the drain pipe 106, preventing cavitation caused by excessively low water level in the intermediate storage tank 103 when the main pipe 104 delivers water. It should be noted that the pump should be started and stopped gradually to avoid pressure fluctuations in the intermediate storage tank 103 caused by sudden changes in flow rate, which could interfere with the connection effect of the main pipe 104.

[0031] Furthermore, a first solenoid valve 107 is connected to the bottom of the water bag 102, and the branch pipe 105 is connected to the water bag 102 through the first solenoid valve 107.

[0032] The first solenoid valve 107, as the core control component between the water bag 102 and the branch pipe 105, can precisely open and close the water flow channel between them according to the actual needs of pre-pressure construction. When the device is in the water filling stage, the connection between the water bag 102 and the branch pipe 105 can be blocked by closing the first solenoid valve 107. At this time, the external water source can independently fill each water bag 102, ensuring that each water bag 102 can complete the water filling operation according to the preset pre-pressure load requirements. This avoids cross-flow of water through the branch pipe 105 during the water filling process, ensuring that the water level and load of each water bag 102 after filling meet the design standards, and providing an accurate load basis for subsequent pre-pressure testing.

[0033] When the device enters the drainage stage, the first solenoid valve 107 is opened, allowing water in the water bag 102 to flow smoothly into the branch pipe 105 and then into the main pipe 104. More importantly, the first solenoid valve 107 can achieve rapid and synchronous control of the water flow. When it is necessary to stop drainage or adjust the drainage process, it can quickly close the channel, effectively preventing excessive water discharge from the water bag 102 due to the inability to stop the water flow in time, preventing unnecessary sudden drops in the load of the hanging basket, and ensuring the stress stability of the hanging basket during the drainage process.

[0034] Furthermore, a second solenoid valve 108 is provided between the main pipe 104 and the intermediate water storage tank 103, and a water injection pipe 109 is connected to the end of the main pipe 104 away from the second solenoid valve 108.

[0035] The second solenoid valve 108, as the core on / off component between the main pipe 104 and the intermediate water storage tank 103, can precisely control the water flow from the main pipe 104 to the intermediate water storage tank 103. When the device is in the water filling stage, closing the second solenoid valve 108 can block the connection between the main pipe 104 and the intermediate water storage tank 103. At this time, external water can be injected into the main pipe 104 through the water injection pipe 109 and distributed to each water bag 102 through the branch pipe 105, ensuring that all the water flow is used to fill the water bags 102. This avoids water loss or decreased filling efficiency caused by water flowing into the intermediate water storage tank 103 in advance during the filling process, and ensures that each water bag 102 can quickly reach the target water level according to the preset load requirements. When the device enters the drainage stage, the second solenoid valve 108 is opened. The water in the water bag 102 flows into the main pipe 104 through the branch pipe 105 and then flows smoothly into the transfer storage tank 103 through the solenoid valve. It is then discharged through the drain pipe 106, realizing the orderly connection of the drainage process. At the same time, the solenoid valve can be closed at any time during the drainage process as needed to suspend the drainage operation, providing a flexible control means for construction adjustment or abnormal handling.

[0036] The cooperation between the second solenoid valve 108 and the water injection pipe 109 (which connects the valve and the water pump) enables "one-way" control of the water filling and drainage process, preventing reverse flow or turbulence of water within the main pipe 104. During filling, water enters through the water injection pipe 109, the second solenoid valve 108 closes, and the water flows directionally towards the water bag 102. During drainage, water intake stops through the water injection pipe 109, the second solenoid valve 108 opens, and the water flows directionally towards the intermediate water storage tank 103. This clear control of the water flow direction effectively prevents pressure fluctuations within the pipe caused by backflow, reduces the occurrence of abnormal water levels in the water bag 102 or leakage at pipe joints, and further ensures the stability and safety of the entire pre-pressurization device during operation.

[0037] Furthermore, a water meter is connected to the water injection pipe 109 to measure the amount of water injected.

[0038] As a metering component on the water injection pipe 109, the water meter is designed and installed to directly serve the needs of precise load control in the preloading operation of the cantilever cast-in-place hanging basket. Through real-time and accurate water injection measurement, it provides key data support for the scientific nature and controllability of the preloading process.

[0039] The core objective of preloading in cantilever cast-in-place formwork is to simulate the actual load of subsequent concrete pouring (such as the self-weight of the beam segment, additional construction loads, etc.) by filling water bags with water. This load has a fixed relationship with the amount of water in the water bags (the density of water is known, water volume × density = water weight, i.e., simulated load). The water meter can display the total amount of water injected from the water injection pipe 109 to the main pipe 104 (and then to each water bag 102) in real time. Construction personnel can accurately control the water injection process based on the "target water injection volume" calculated from the design load. When the water meter reading reaches the target value, water injection can be stopped, avoiding problems such as insufficient load (unable to verify the load-bearing limit of the formwork) or excessive load (potentially damaging the formwork structure) caused by "estimating the water volume based on experience". This ensures that the preloading load is highly consistent with the design requirements.

[0040] Furthermore, the top circumference of the transfer water tank 103 is provided with multiple first vent holes 110, and the top of the water bag 102 is provided with a second vent hole 111.

[0041] The multiple circumferential vents 110 on the top of the transfer water tank 103 are a key design feature for maintaining pressure balance and ensuring safe operation. From a pressure balance perspective, the transfer water tank 103, acting as a transfer hub for the drainage of the water bag 102, continuously receives water from the main pipe 104 during drainage. When the water level rises, internal air must be expelled promptly to prevent increased pressure from hindering water flow. Conversely, when the drain pipe 106 drains water, the water level drops, requiring outside air to enter and replenish the space, preventing negative pressure from slowing or halting drainage. Positioning the vents 110 at the top ensures that the air intake and exhaust paths are always above the water level, effectively preventing water from overflowing from the vents. Furthermore, the multiple circumferential vents on the top disperse the air intake and exhaust paths, reducing the impact of blockage at a single vent and ensuring stable pressure balance.

[0042] The second vent 111 at the top of the water bag 102 has the core function of balancing the air pressure inside and outside the water bag 102, ensuring a stable filling and draining process and controllable water flow rate. During the filling stage, as external water flows into the water bag 102 through the branch pipe 105, the volume of the water bag 102 gradually expands. The internal air needs to be discharged in time through the second vent 111. Without this vent, the internal air pressure will increase with the increase of water volume, which will not only hinder the continued water flow but may also cause the water bag 102 (made of flexible composite material) to rupture due to excessive air pressure, affecting the safety of the pre-compression operation. During the draining stage, the water volume inside the water bag 102 decreases and its volume shrinks. External air needs to enter through the second vent 111 to avoid the formation of negative pressure inside, which would cause a sudden drop in the draining speed or even prevent the water from draining.

[0043] Although the first vent 110 and the second vent 111 act on the intermediate water storage tank 103 and the water bag 102 respectively, they work together to form a pressure regulation system for the core water storage component of the covering device, jointly ensuring the smoothness and stability of the pre-pressurization device's filling and draining process. During the draining process, the water bag 102 draws in air through the second vent 111 and smoothly discharges water to the branch pipe 105. After the water flows through the branch pipe 105 into the main pipe 104, it enters the intermediate water storage tank 103. At this time, the intermediate water storage tank 103 discharges air through the top first vent 110 and stably receives the water flow. Then, it draws in air again through the first vent 110, allowing the water inside the tank to flow smoothly out through the drain pipe 106. Throughout the process, both vents eliminate the pressure obstruction problem of the water bag 102 and the intermediate water storage tank 103, ensuring that the water flow is always smoothly transported under gravity and avoiding fluctuations in drainage speed caused by pressure differences.

[0044] Furthermore, a dust cover 112 is provided on the second vent 111.

[0045] The core function of the second vent 111 is to balance the air pressure inside and outside the water bag 102, ensuring smooth filling and drainage. The dust cover 112 is a breathable cover structure, with a filter screen or sponge as the middle part of the cover body. It can effectively prevent dust, sand, fallen leaves, and other impurities in the construction environment from entering the vent without obstructing airflow. In road and bridge construction scenarios, there is often a lot of dust and floating debris on site. Without the dust cover 112, impurities can easily accumulate in the vent, which may lead to blockage over time. A blocked vent cannot achieve normal air pressure balance, causing problems such as excessively high internal air pressure when filling the water bag 102 and negative pressure when draining. This can affect the water flow rate and even cause the water bag 102 to rupture due to abnormal pressure, compromising the stability of the pre-compression operation. The dust cover 112 directly cuts off the path for impurities to enter, ensuring that the second vent 111 remains unobstructed and that its air pressure regulation function remains effective.

[0046] Furthermore, the drain pipe 106 is connected to the lower side of the intermediate water storage tank 103, and the horizontal height of the connection between the drain pipe 106 and the intermediate water storage tank 103 is lower than the horizontal height of the connection between the main pipe 104 and the intermediate water storage tank 103.

[0047] The drain pipe 106 is connected to the lower side of the intermediate water storage tank 103, rather than being directly installed at the bottom of the tank. The core reason for this is to reduce the risk of blockage by optimizing the connection position and ensuring long-term unobstructed drainage. Considering the sedimentation patterns of impurities, the water in the intermediate water storage tank 103 may carry small amounts of silt, construction debris, and other impurities during long-term use. These impurities, due to their high density, tend to settle at the bottom of the tank under gravity. If the drain pipe 106 were placed directly at the bottom, the deposited impurities would accumulate directly at the pipe inlet, potentially leading to blockage over time, causing drainage stagnation, and disrupting the drainage process of the pre-pressurization device.

[0048] Connecting the drain pipe 106 to the lower side, with its inlet positioned higher than the sediment layer at the bottom of the water tank, effectively avoids deposited impurities and reduces the probability of impurities entering the pipe. Simultaneously, this lower side connection ensures that most of the water in the tank drains smoothly under gravity, avoiding the blockage risks associated with bottom connections while retaining the advantages of gravity drainage. This achieves efficient drainage without the need for additional power equipment, balancing drainage smoothness with device operational stability.

[0049] Furthermore, the lower end of the transfer water storage tank 103 is open, and the lower end opening of the transfer water storage tank 103 is threadedly sealed with a cleaning cover 113.

[0050] The design of the lower end of the transfer water tank 103 being open is a core design feature to address the need for cleaning and maintenance of the tank's interior. As a water transfer hub, the transfer water tank 103 will accumulate sediment, construction debris, and other impurities carried in the water due to gravity at the bottom of the tank during long-term use. If the tank is a closed structure, the accumulated impurities are difficult to clean. Over time, this accumulation will not only occupy the tank's volume and affect the efficiency of water storage and delivery, but may also clog pipe joints (such as the connection with the main pipe 104 and the drain pipe 106), leading to obstructed water flow and disrupting the stability of the drainage system.

[0051] The lower opening provides a direct channel for cleaning impurities: when it's necessary to clean deposited impurities, there's no need to disassemble the entire water tank or complex piping; simply opening the lower opening allows direct access to and removal of the bottom deposits, making the operation convenient and ensuring thorough cleaning. Simultaneously, this opening design also facilitates internal maintenance of the water tank. Workers can inspect the inner wall of the tank for wear, corrosion, or other defects, promptly identifying and addressing potential faults, extending the tank's lifespan, and ensuring the long-term stable operation of its transfer function.
