Description

Technical Field

[0001] The utility model relates to the field of dike disaster prevention and reduction and flood control engineering, in particular to an elevation adaptive pressure relief well based on dike seepage safety. Background Art

[0002] In the field of seepage control measures for levee sand foundations, pressure relief wells are often designed and arranged along the downstream of the levee to drain water to prevent pipe bursts and other seepage deformation and damage. The drainage volume of the levee pressure relief well is an important indicator of the flood control role of the pressure relief well. However, due to the well completion effect of the pressure relief well, the uncertainty of the formation conditions, and the easy clogging of the pressure relief well, the drainage volume cannot be accurately predicted and the performance cannot be guaranteed. The elevation of the pressure relief well is an important indicator that affects the drainage volume. In the past engineering design and promotion and application, it has not received enough attention, and the engineering effect of the pressure relief well has not been fully utilized.

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-3 As shown, the utility model is a height-adaptive pressure relief well based on dike seepage safety control, comprising:

[0022] Pressure relief well outer pipe 4;

[0023] A curved stoplog door 7 is slidably disposed on the inner wall of the outer pipe 4 of the pressure relief well;

[0024] The electronic water level meter 1 is installed on the water-facing side of the dike, and is used to collect the water level information of the outer river during the flood season, and obtain the water level height of the outer river in real time and accurately;

[0025] A driving mechanism, used for driving the curved stoplog door 7 to move up and down along the inner wall of the outer pipe 4 of the pressure relief well;

[0026] The PLC control device 2 is connected to the water level meter 1 and the driving mechanism, and is used to obtain the water level height of the outer river according to the electronic water level meter 1, and obtain the required safe water inflow and the corresponding wellhead elevation according to the water level height of the outer river. If the wellhead elevation corresponding to the safe water inflow is too high, the PLC control device 2 controls the driving mechanism to drive the curved stacked beam door 7 to move slowly downward along the inner wall of the outer pipe 4 of the pressure relief well through the deadweight of the pressure relief well inner pipe 8, so as to adjust the height of the curved stacked beam door 7 to reach the wellhead elevation corresponding to the safe water inflow; if the wellhead elevation corresponding to the safe water inflow is too low, the PLC control device 2 controls the driving mechanism to drive the curved stacked beam door 7 to move slowly upward along the inner wall of the outer pipe 4 of the pressure relief well by tightening the cable 601 to lift the pressure relief well inner pipe 8, so as to adjust the height of the curved stacked beam door 7 to reach the wellhead elevation corresponding to the safe water inflow, thereby realizing adaptive adjustment of the wellhead elevation.

[0027] The solar power supply panel 3 is electrically connected to the PLC control device 2 and is used to supply power to the PLC control device 2 .

[0028] The outer tube 4 of the pressure relief well is riveted with a truss 5, and the driving mechanism includes a small winch 6 and a cable 601. The small winch 6 is fixed to the truss 5, and the small winch is connected to the curved stop beam door 7 through the cable 601. The lifting and lowering of the curved stop beam door 7 is controlled by the winch 6 to adjust the elevation of the pressure relief well. Pulleys 8 are installed at both ends of the curved stop beam door 7, which are slidably connected to the inner wall of the outer tube 4 of the pressure relief well through a slide rail 9. An electromagnetic flowmeter 10 is provided between the pressure relief well and the drainage pipe to measure the flow of the pressure relief well and compare it with the safe water inflow, thereby realizing dynamic management of the pressure relief well and ensuring the safety of dike seepage.

[0029] The utility model takes into account the influence of the relief well head elevation on the water inflow, and dynamically adjusts the relief well head elevation in real time to meet the requirement of stable seepage in dangerous sections of the dike. The implementation principle is as follows:

[0030] The PLC control device 2 obtains the real-time water level of rivers, lakes and reservoirs outside the dike through the electronic water level meter 1, obtains the required safe water inflow and the corresponding wellhead elevation according to the real-time water level, and further adjusts the height of the curved stop beam gate 7 through the PLC control device 2 to achieve adaptive adjustment of the wellhead elevation, thereby achieving the effect of meeting the seepage safety of the dike; an electromagnetic flow meter 10 is provided at the downstream drainage ditch to obtain the drainage volume of the pressure relief well, and compare it with the safe flow water inflow, thereby achieving dynamic management of the pressure relief well and ensuring the seepage safety of the dike. Specifically, when the actual flow measured by the electromagnetic flow meter 10 is lower than the safe flow, the PLC control device 2 will start the small winch 6 to loosen the cable 601. At this time, the curved stop beam gate 7 will slide downward along the inner wall of the well pipe 4 due to its own weight to achieve dynamic changes in the wellhead elevation. At this time, the water inflow of the pressure relief well and its drainage and pressure relief capacity will be improved. By repeatedly comparing the measured flow rate of the electromagnetic flowmeter 10 with the safe flow rate, the wellhead elevation is adjusted to the optimal range, and the dynamic management process of the pressure relief well flow rate, the outer river water level elevation, and the wellhead elevation is realized. It has the advantages of systematization, real-time feedback, rapid response, refined regulation and easy maintenance. It is suitable for layout in sections prone to dangerous situations during flood season to ensure the safety of embankment seepage.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by technicians in this technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
