Description

TECHNICAL FIELD

[0001] The present application relates to a surge wave preventing lifting pile system and method. BACKGROUND

[0002] In the field of water conservancy and marine protection, the prevention of surge waves has always been a key challenge. Traditional fixed wave protection dikes and seawalls, while able to block surge waves to some extent, protect coastal facilities, but these structures often come at the cost of sacrificing landscape views and environmental aesthetics. For example, continuous concrete wave protection dikes not only visually cut off the connection between people and water areas, but also can affect the natural ecosystems of coastal areas, limiting the opportunities for the public to approach water areas. In addition, the construction and maintenance costs of fixed wave protection structures are high, and once built, it is 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

[0003] The technical problem to be solved by the present application is to provide a surge wave preventing lifting pile system and method to solve the problem of people's landscape view and blocking of surge waves.

[0004] To solve the above problems, the technical scheme of the present application is:

[0005] A surge wave preventing lifting pile system, comprising a platform and a shore slope, a plurality of rows of lifting piles are arranged around the platform, adjacent two rows of lifting piles are staggered, and a plurality of hydrological sensing devices are arranged on the edge of the shore slope, each hydrological sensing device transmits the detected signal to the control center, and the control center controls the action of each lifting pile.

[0006] The hydrological sensing device comprises a water flow velocity sensor and a wave height sensor, the distance between adjacent two hydrological sensing devices is L > 2v-s, v is the maximum propagation speed of the surge wave, s is the lifting time of the lifting pile.

[0007] A wave prevention amount calculation module and an impact force bearing calculation module are arranged in the control center.

[0008] The wave prevention amount calculation module is used to estimate the wave prevention effect of the lifting pile under the action of the surge wave, and the wave prevention amount calculation module is calculated based on the following formula:

[0009]

[0010] Hr is the remaining wave height (m) after passing through the lifting pile; H 0 is the original wave height (m); D is the diameter of the lifting pile (m); Lis the effective spacing (m) of the lift pile under the surge action; k is the wave attenuation coefficient (m -1 ); e is the base of the natural logarithm.

[0011] The impact force bearing calculation module is used to evaluate the bearing force of the lift pile under the surge impact, and the impact force bearing calculation module is calculated based on the following formula:

[0012] F = 0.5 pC d AV 2

[0013] wherein, F represents the impact force (N); p represents the density of water (kg / m 3 ); C d represents the resistance coefficient; A represents the area (m 2 ) of the front of the lift pile impacted by the wave; V represents the flow velocity of the wave (m / s).

[0014] Comprise the following steps: initially, a plurality of hydrological sensing devices are used to monitor the surge situation in real time, and a plurality of rows of lift piles are in a retracted state;

[0015] S1: the hydrological sensing device monitors the surge propagation speed and surge height in real time, and transmits the data to the control center;

[0016] S2: when the control center receives the early warning signal, the control center controls each lift pile to rise to form a wave protection barrier;

[0017] S3: after the surge ends, the control center controls the lift pile to return to the initial state and waits for the next early warning signal.

[0018] The beneficial effects of the present application are:

[0019] (1) Concealment and functionality: the lift pile can be completely concealed under the ground during the non-surge period, without affecting the landscape, maintaining good visual experience, and being suitable for use in coastal areas, ports and other areas. When the surge occurs, the system can quickly respond to make the lift pile rise from the ground to form an effective wave protection barrier, thereby reducing the damage of the surge to the coastal facilities and the ecological environment, and protecting the safety of the coastline.

[0020] (2) The hydrological sensing device can predict the occurrence of the surge and timely adjust the height and position of the lift pile, thereby effectively reducing the maintenance cost. At the same time, the system can also be remotely monitored, so that the management personnel can timely understand the system operation status.

[0021] (3) Prefabricated modular design and construction: The prefabricated modular design simplifies the construction process, shortens the construction cycle, and improves construction efficiency. This design method also has high flexibility and can be adjusted and expanded according to actual needs. In addition, the prefabricated modular design facilitates transportation and installation, reducing transportation costs and installation difficulty. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 3 As shown, a surge protection lifting pile system includes a platform 4 and a bank slope 2. Two rows of lifting piles 3 are arranged around the perimeter of the platform 4. Each row of lifting piles 3 consists of multiple cylindrical lifting piles 3. The fully raised height of the lifting piles 3 is 5m, the depth of the piles 3 is 6m into the platform, the outer diameter is 80cm, the spacing between two adjacent lifting piles 3 is 60mm, and the adjacent rows of lifting piles 3 are staggered. The system also includes multiple hydrological sensing devices 1 arranged on the side of the bank slope 2. Each hydrological sensing device 1 transmits the detected signal to the control center 6, and the control center 6 controls the operation of each lifting pile 3.

[0029] The deployment range of the lifting piles 3 is calculated based on three-dimensional numerical simulation, such as using Flow 3D numerical calculation software, to simulate the impact of the historical maximum surge on the bank slope 2, calculate the direction and range of the surge, and only deploy the lifting piles 3 in the area where the surge poses a disaster risk.

[0030] The lifting height of the lifting pile 3 is calculated according to the wave height, and the sum of the height of the revetment and the lifting height of the wave prevention pile is 1.2 times the wave height. If the monitored wave height is 10 m and the height of the revetment is 8 m, the lifting height of the lifting pile 3 needs to be greater than 4 m.

[0031] In use, in a natural state, the lifting pile 3 is sunken in the ground to reduce visual obstruction. When the wave monitoring device gives an early warning, the lifting pile 3 is lifted from the ground to block the wave, and after the alarm is lifted, the lifting pile 3 automatically falls down.

[0032] In addition, compared with the hydraulic flood prevention baffle, the cylindrical structure of the lifting pile 3 can first disperse wave energy under the action of the wave, reducing the direct impact on the structure; secondly, the vertical up-and-down stretching of the lifting pile 3 can occupy less surface space, and can extend to a higher height relative to the surface, and can resist a larger range of waves; finally, the wave is easy to climb up along the low-angle inclined hydraulic flood prevention baffle, and the angle has a great influence, and usually only at a high angle can the protection range be relatively strong. The blocking effect of the vertical structure of the hydraulic pile is more obvious.

[0033] The hydrological sensing device 1 includes a flow velocity sensor and a wave height sensor, and the distance between two adjacent hydrological sensing devices 1 is L > 2v-s, v The wave history maximum propagation speed is s The lifting time of the lifting pile 3 is, for example, if the wave history maximum propagation speed is 5 m / s, the lifting pile 3 needs 10 s to rise to the highest, and the monitoring device needs to be arranged 100 m away.

[0034] The control center 6 is provided with a wave prevention amount calculation module and an impact force bearing calculation module. The control center 6 is a computer, the lifting pile 3 is a hydraulic stainless steel lifting pile 3, an electromagnetic valve for controlling the lifting of the lifting pile 3 is connected with the PLC controller 7, the PLC controller 7 is connected with the control center 6 through a communication cable for communication, and the 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.

[0035] The wave prevention amount calculation module is used to estimate the wave prevention effect of the lifting pile 3 under the action of the wave, and the wave prevention amount calculation module is calculated based on the following formula:

[0036]

[0037] Hr The remaining wave height after passing through the lifting pile 3 is (m); H 0 is the original wave height (m); D The diameter of the lifting pile 3 is (m); L The effective distance of the lifting pile 3 under the action of the wave is (m); k The wave attenuation coefficient is (m -1 ); eThe base of the natural logarithm is 2.7.

[0038] The impact force bearing calculation module is used to evaluate the bearing force of the lifting pile 3 under the surge impact, and the impact force bearing calculation module is calculated based on the following formula:

[0039] F = 0.5 pC d AV 2

[0040] Wherein, F represents the impact force (N); p represents the density of water (kg / m 3 ); C d represents the resistance coefficient; A represents the area of the front of the lifting pile 3 impacted by the wave (m 2 ); V represents the flow velocity of the wave (m / s).

[0041] The method comprises the following steps: initially, the plurality of hydrological sensing devices 1 are used to monitor the surge situation in real time, and the plurality of rows of lifting piles 3 are in a retracted state;

[0042] S1: The hydrological sensing device 1 monitors the surge propagation speed and the surge height in real time, and transmits the data to the control center 6;

[0043] S2: When the control center 6 receives the early warning signal, the control center 6 controls each lifting pile 3 to rise through the PLC controller 7, thereby forming a wave protection barrier;

[0044] S3: After the surge ends, the control center 6 controls the lifting pile 3 to return to the initial state, and waits for the next early warning signal.

[0045] The content described in the embodiments of the present specification is only a list of implementation forms of the inventive concept, and the protection scope of the present application should not be regarded as being limited to the specific forms described in the embodiments, and the protection scope of the present application also extends to equivalent technical means that can be thought of by those skilled in the art according to the inventive concept.
