Description

Technical Field

[0001] The invention relates to a surge-proof lifting pile system and method. Background Art

[0002] In the existing field of water conservancy engineering and marine protection, the prevention and control of swells has always been a key challenge. Although traditional fixed breakwaters and sea walls can block swells and protect coastal facilities to a certain extent, these structures often come at the expense of landscape views and environmental aesthetics. For example, continuous concrete breakwaters not only visually cut off the connection between people and the water, but may also affect the natural ecosystem of coastal areas and limit the public's access to the water. In addition, fixed wave-breaking structures are expensive to build and maintain, and once built, they are difficult to adjust according to environmental changes. The rigidity and permanence of these structures also make them less flexible and adaptable in the face of long-term environmental changes such as climate change and sea level rise. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a surge-proof lifting pile system and method, which are used to solve the problem that people's landscape vision and surge-proofing cannot be taken into account at the same time.

[0004] In order to solve the above problems, the technical solution of the present invention is: A surge protection lifting pile system comprises a platform and a bank slope. A plurality of rows of lifting piles are arranged on the periphery of the platform, and two adjacent rows of lifting piles are arranged in a staggered manner. The system also comprises a plurality of hydrological sensing devices arranged on the bank slope. Each hydrological sensing device transmits a detected signal to a control center, and the control center controls the action of each lifting pile.

[0005] The hydrological sensing device includes a water flow velocity sensor and a wave height sensor. The distance between two adjacent hydrological sensing devices is L>2v·s,v is the maximum propagation speed of the surge in history, s It is the rising time of the lifting pile.

[0006] The control center is equipped with a wave protection calculation module and an impact force bearing calculation module.

[0007] The wave protection amount calculation module is used to estimate the wave protection effect of the lifting pile under the action of surge waves. The wave protection amount calculation module calculates the wave protection amount based on the following formula:

[0008] Hr is the residual wave height after the lifting pile (m); H 0 is the original wave height (m); D is the diameter of the lifting pile (m); L is the effective spacing of lifting piles under surge (m); k is the wave attenuation coefficient (m-1 ); e is the base of natural logarithms.

[0009] The impact force bearing calculation module is used to evaluate the bearing capacity of the lifting pile under the impact of surge waves. The impact force bearing calculation module calculates the impact bearing capacity based on the following formula: F = 0.5 ρC d AV 2 in, F Indicates the impact force (N); ρ Indicates the density of water (kg / m 3 ); C d represents the drag coefficient; A Indicates the area of ​​the lifting pile front impacted by waves (m 2 ); V Indicates the velocity of the wave (m / s).

[0010] The method comprises the following steps: initially, a plurality of hydrological sensing devices are used to monitor the surge conditions in real time, and a plurality of rows of lifting piles are in a retracted state; S1: The hydrological sensing device monitors the surge propagation speed and surge height in real time and transmits the data to the control center; S2: When the control center receives the warning signal, the control center controls each lifting pile to rise to form a wave-breaking barrier; S3: After the surge ends, the control center controls the lifting piles to return to the initial state and wait for the next warning signal.

[0011] The beneficial effects of the present invention are: (1) Concealment and functionality: The lifting piles can be completely concealed under the ground during non-surge periods, without affecting the landscape, maintaining a good visual experience, and are suitable for use in coastlines, ports and other areas. When a surge occurs, the system can respond quickly, raising the lifting piles from the ground to form an effective wave barrier, thereby reducing the damage of surges to coastal facilities and the ecological environment, and protecting the safety of the coastline.

[0012] (2) The hydrological sensing device can predict the occurrence of surge waves and adjust the height and position of the lifting piles in a timely manner, thereby effectively reducing maintenance costs. At the same time, the system can also be remotely monitored, allowing managers to understand the system operation status in a timely manner.

[0013] (3) Prefabricated modular design and construction: The prefabricated modular design simplifies the construction process, shortens the construction period, and improves construction efficiency. This design method is also highly flexible and can be adjusted and expanded according to actual needs. In addition, the prefabricated modular design is also easy to transport and install, reducing transportation costs and installation difficulties. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below in conjunction with the accompanying drawings: Figure 1 This is a layout diagram of the lifting pile and surge monitoring equipment of the present invention. Figure 2 is a top view of the present invention, Figure 3 It is a structural schematic diagram of the present invention.

[0015] In the figure: hydrological sensing device 1, slope 2, lifting piles 3, platform 4, 4G communication module 5, control center 6, PLC controller 7. DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figures 1 to 3 As shown, a surge protection lifting pile system includes a platform 4 and a slope 2. Two rows of lifting piles 3 are arranged on the periphery of the platform 4. Each row of lifting piles 3 is composed of a plurality of cylindrical lifting piles 3. The lifting piles 3 are 5m high when fully raised, 6m buried in the platform, with an outer diameter of 80cm. The spacing between two adjacent lifting piles 3 is 60mm. The two adjacent rows of lifting piles 3 are staggered. The system also includes a plurality of hydrological sensing devices 1 arranged on the side of the slope 2. Each hydrological sensing device 1 transmits a detected signal to a control center 6, and the control center 6 controls the action of each lifting pile 3.

[0018] The arrangement range of the lifting piles 3 is calculated based on three-dimensional numerical simulation, such as Flow 3D numerical calculation software, which simulates the attack of the largest surge in history on the slope 2, calculates the attack direction and range of the surge, and arranges the lifting piles 3 only in the surge disaster risk area.

[0019] The lifting height of the lifting pile 3 is calculated according to the surge height, and the sum of the slope protection height and the wave-breaking pile lifting height is 1.2 times the surge height. If the monitored surge height is 10m and the slope protection height is 8m, the lifting height of the lifting pile 3 needs to be greater than 4m.

[0020] When in use, in the natural state, the lifting pile 3 sinks to the ground to reduce the line of sight obstruction. When the surge monitoring device issues an early warning, the lifting pile 3 rises from the ground to block the surge. After the alarm is lifted, the lifting pile 3 automatically falls.

[0021] In addition, compared with the hydraulic flood baffle, the cylindrical structure of the lifting pile 3 can disperse the wave energy under the action of waves and reduce the direct impact on the structure; secondly, the vertical extension and retraction of the lifting pile 3 can occupy less surface space, and the height that can be extended relative to the surface is higher, and the range of resisting surge is larger; finally, surge waves tend to climb upward along the low-angle inclined hydraulic flood baffle, and the angle has a great influence. Usually, the protection range is stronger only at high angles. The vertical structure of the hydraulic pile has a more obvious blocking effect.

[0022] The hydrological sensing device 1 includes a water flow velocity sensor and a wave height sensor. The distance between two adjacent hydrological sensing devices 1 L>2v·s,v is the maximum propagation speed of the surge in history, s is the rising time of the lifting pile 3. If the maximum propagation speed of the surge is 5m / s, and the maximum time required for the lifting pile 3 to rise is 10s, the monitoring device needs to be arranged 100m away.

[0023] A wave protection amount calculation module and an impact force bearing calculation module are provided in the control center 6. The control center 6 is a computer, the lifting pile 3 is a hydraulic stainless steel lifting pile 3, and the solenoid valve for controlling the lifting of the lifting pile 3 is connected to the PLC controller 7, and the PLC controller 7 is connected to the control center 6 through a communication cable for communication. The water flow velocity sensor and the wave height sensor transmit the detected data to the control center 6 in real time through the 4G communication module 5.

[0024] The wave protection amount calculation module is used to estimate the wave protection effect of the lifting pile 3 under the action of swell waves. The wave protection amount calculation module calculates the wave protection amount based on the following formula:

[0025] Hr is the residual wave height after passing through the lifting pile 3 (m); H 0 is the original wave height (m); D is the diameter of the lifting pile 3 (m); L is the effective spacing of the lifting piles 3 under the action of surge (m); k is the wave attenuation coefficient (m -1 ); e is the base of the natural logarithm, and its value is 2.7.

[0026] The impact force bearing calculation module is used to evaluate the bearing capacity of the lifting pile 3 under the impact of surge waves. The impact force bearing calculation module calculates the impact bearing capacity based on the following formula: F= 0.5 ρC d AV 2 in, F Indicates the impact force (N); ρ Indicates the density of water (kg / m 3 ); C d represents the drag coefficient; A represents the area of ​​the lifting pile 3 that is impacted by waves (m 2 ); V Indicates the velocity of the wave (m / s).

[0027] The method comprises the following steps: initially, a plurality of hydrological sensing devices 1 are used to monitor the surge conditions in real time, and a plurality of rows of lifting piles 3 are in a retracted state; S1: Hydrological sensing device 1 monitors the wave propagation speed and wave height in real time, and transmits the data to the control center 6; S2: When the control center 6 receives the warning signal, the control center 6 controls the lifting piles 3 to rise through the PLC controller 7 to form a wave barrier; S3: After the surge ends, the control center 6 controls the lifting pile 3 to return to the initial state and wait for the next warning signal.

[0028] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the inventive concept. The protection scope of the present invention should not be regarded as limited to the specific forms described in the embodiments. The protection scope of the present invention also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
