Description

Technical Field

[0001] The present invention relates to the field of revetment structures, and particularly to a modular hydraulic-driven revetment structure and its dynamic flood control and flood discharge method. Background Art

[0002] A revetment structure is a structure used to protect riverbanks or lake shores from erosion by natural forces such as water flow, wind waves, etc. With the continuous progress of technology, the design and construction techniques of revetment structures are also constantly updated and improved.

[0003] Common revetment structures can be divided into slope-type revetments (such as dry-laid stone revetments), dam-type revetments (spur dikes and guide dikes), wall-type revetments (such as gravity retaining walls), and other revetment structures (such as gabion revetments). Although these revetment structures have their own unique advantages in design and function, there is a common limitation, that is, most of these revetment structures are fixed. Due to the fixed revetment structure, when the water level changes significantly, the revetment structure may not be able to effectively respond. During the flood season or when discharging flood upstream, if the height of the revetment is insufficient, it may cause the flood to overflow the revetment structure, threatening both sides of the riverbank. In addition, the high water level may exert huge pressure on the revetment structure, even causing the overall or partial damage of the revetment structure. On the contrary, in the dry season, the revetment structure used to block floods may appear too tall, not only affecting the landscape effect, but also possibly hindering the natural flow pattern and ecological restoration of the river channel.

[0004] In recent years, although some revetment structures with adjustable height have emerged, there are still some deficiencies. First of all, the adjustable retaining wall of the existing structure usually can only achieve lifting in a single direction (vertical direction), and it is difficult to achieve retaining walls at different angles, and it cannot adapt to the complex and changeable water level changes. Especially in the case of rapid rising or falling of the water level, the adjustment ability of the existing structure is limited, which may lead to poor flood control effect. For example, some structures rely solely on the buoyancy of water to adjust the height of the retaining wall, resulting in low reliability of the retaining wall. It is possible that the water has overflowed the retaining wall, but the height of the adjustable retaining wall has not yet risen to the target position, thus greatly reducing the flood control effect. Secondly, the flood discharge function of the existing structure is relatively single, lacking a dynamic adjustment mechanism, and it is difficult to effectively control the flood flow, thus affecting the overall effect of flood control and flood discharge. These problems are particularly prominent under extreme climate conditions, posing higher requirements for the stability and reliability of the flood control system. Summary of the Invention

[0005] The purpose of the present invention is to provide a modular hydraulic-driven revetment structure, including an anti-seepage curtain, a foundation, an adjustable retaining wall, side walls, flood control boards, and a pulley system.

[0006] The layout of the basic shoreline includes Foundation I on the riverside side and Foundation II on the back-river side. An anti-seepage curtain is provided below Foundation I, and a side wall is provided above Foundation II.

[0007] The adjustable water retaining wall includes a lower wall, an upper wall, and an upper wall fixing device.

[0008] The lower wall is connected to Foundation I, and a cavity is formed between the lower wall and the foundation and the side wall.

[0009] The upper wall includes three installation modes, namely:

[0010] Mode I: Both ends of the upper wall are respectively lapped on the top surface of the lower wall and the top surface of the side wall, and the upper wall is vertically arranged with the lower wall.

[0011] Mode II: One end of the upper wall is lapped on the top surface of the lower wall, and the other end is set in the air and fixed by the upper wall fixing device. The upper wall is arranged at an obtuse angle with the lower wall.

[0012] Mode III: The upper wall is located above the lower wall and is arranged parallel to the lower wall.

[0013] A number of L-shaped drainage holes are arranged at intervals on the end of the upper wall close to the lower wall. One end of the L-shaped drainage hole penetrates the bottom surface of the upper wall and communicates with the outside, and the other end penetrates the backwater side side wall of the upper wall and communicates with the outside.

[0014] A number of chutes are arranged at intervals on the backwater side of the upper wall, and a number of pins are arranged at intervals in the chutes.

[0015] The upper wall fixing device includes a motor fixed on the top of the side wall and a hydraulic rod connected to the motor. The hydraulic rod is a telescopic rod.

[0016] The motor drives the hydraulic rod to rotate, thereby supporting the upper wall and enabling the upper wall to transition from Mode I to Mode II. When the upper wall is in Mode II, the telescopic end of the hydraulic rod extends into the chute and is fixed by the pin.

[0017] Flood discharge holes penetrating the side wall are arranged at intervals at the bottom of the side wall, and pulley systems are provided on both the water-facing side and the backwater side of the side wall.

[0018] The pulley system includes a pulley and a chain. One end of the chain is fixed to the top of the side wall, and the other end bypasses the pulley and is connected to the flood control board. The lifting of the flood control board is controlled by the pulley system.

[0019] Furthermore, the upper wall includes a number of retaining wall blocks, and adjacent retaining wall blocks are connected by a mortise and tenon structure.

[0020] The chute is an inverted convex chute, including Chute I and Chute II. The length of Chute II is greater than the length of Chute II.

[0021] A chute Ⅰ or a chute Ⅱ is provided in the middle of the water-facing side of the retaining wall block, and the retaining wall blocks provided with the chute Ⅰ and the retaining wall blocks provided with the chute Ⅱ are arranged at intervals.

[0022] Furthermore, the latch pin includes a retracted mode and a popped-out mode.

[0023] When the latch pin is in the retracted mode, the latch pin is flush with the chute.

[0024] When the latch pin is in the popped-out mode, the latch pin extends out of the chute.

[0025] The two modes are controlled by a spring plate arranged in the chute. The spring plate is arranged below the latch pin. When the spring plate pops out, it drives the latch pin to pop out together.

[0026] The retraction and popping-out of the spring plate are controlled by a micro motor.

[0027] Furthermore, a brake is provided on the pulley shaft of the pulley.

[0028] Furthermore, an arc-shaped flange is provided on the top surface of the lower wall, and an arc-shaped groove is provided on the bottom surface of the upper wall. The shape of the flange is adapted to the shape of the groove.

[0029] When the upper wall is in mode Ⅲ, the flange of the lower wall is embedded in the groove of the upper wall, and the upper wall is clamped with the lower wall.

[0030] Furthermore, a hardened layer is laid between the foundation Ⅰ and the foundation Ⅱ.

[0031] Furthermore, a grille plate is provided between the upper wall and the side wall.

[0032] Furthermore, the size of the flood control plate is larger than the size of the flood discharge hole.

[0033] Furthermore, a sleeve is provided outside the pulley system.

[0034] Another object of the present invention is to provide a dynamic flood control and flood discharge method based on a modular hydraulic drive type revetment structure.

[0035] When in the dry season, the installation mode of the upper wall is mode Ⅰ.

[0036] When in the flood season:

[0037] If the water level does not exceed the lower wall, the installation mode of the upper wall is mode Ⅰ.

[0038] If the water level exceeds the lower wall but does not exceed the horizontally placed upper wall, and the water level in the cavity does not exceed 2 / 3 of the height of the lower wall, the installation mode of the upper wall is mode Ⅱ. The revetment structure introduces water into the cavity through the drainage holes at the bottom of the upper wall. At this time, the flood control plates on both sides of the side wall block the flood discharge holes.

[0039] When the water level in the cavity exceeds 2 / 3 of the height of the lower wall, the installation mode of the upper wall is still Mode II. The revetment structure introduces water into the cavity through the drainage holes at the bottom of the upper wall. At this time, the flood control board is lifted through the pulley system, and the water in the cavity flows into the municipal pipeline or the river ditch through the flood discharge holes.

[0040] When the water level in the cavity exceeds 5 / 6 of the height of the lower wall, the installation mode of the upper wall is Mode III.

[0041] The technical effects of the present invention are beyond doubt. The beneficial effects of the present invention are as follows:

[0042] The present invention adopts a modular design of an adjustable water retaining wall and a flood control board, combined with a hydraulic drive mechanism, to achieve flexible adjustment and efficient flood control of the revetment structure. Its advantages are as follows: on the one hand, through the horizontal and vertical conversion of the upper wall, it effectively adapts to different water level changes and enhances the water retaining performance of the revetment; on the other hand, the flood discharge holes at the bottom of the side wall, the lifting mechanism of the flood control board, and the design of the grid diversion holes achieve dynamic control and diversion of floods, effectively reducing the impact of floods on the riverbank and improving the efficiency and safety of flood control and flood discharge.

[0092] When in the flood season:

[0093] If the water level does not exceed the lower wall 4, the installation mode of the upper wall 5 is Mode I.

At this time, the flood control plate 12 is lifted through the pulley system, and the water in the cavity flows into the municipal pipeline or the riverbank ditch through the flood discharge holes 15.

[0096] If the water level in the cavity exceeds 5 / 6 of the height of the lower wall 4, the installation mode of the upper wall 5 is Mode III.

[0097] Embodiment 11:

[0098] The main structure of this embodiment is the same as any one of Embodiments 1 to 10. Further, it is a modular hydraulic-driven revetment structure and its dynamic flood control and flood discharge method. The revetment structure includes key components such as the foundation 3, adjustable water retaining walls 4, 5, side wall 16, and flood control plate 12. The foundation 3 is arranged along the entire length of the shore, and two rows of plum blossom-shaped anti-seepage curtains 1 are provided below to enhance its anti-seepage performance. The adjustable water retaining wall is composed of the lower wall 4 and the upper wall 5. The lower wall 4 is connected to the foundation 3, and the upper wall 5 is horizontally lapped above the lower wall 4, and flood control holes and drainage holes are provided at its bottom (the drainage holes here are straight holes, which are connected to the flood control holes to form L-shaped holes). A chute 8 is provided on the backwater side of the upper wall 5. Through the cooperation of the hydraulic rod and the pin 20, the upper wall 5 can be flexibly converted from the horizontal direction to the vertical direction to adapt to different water level changes. The flood discharge holes 15 and the flood control plates 12 are arranged in a staggered manner at the bottom of the side wall 16. The flood control plates 12 are lifted and lowered through the pulley 9 and chain 10 mechanism to control the flood flow. In addition, a grille is provided between the lower wall 4 and the side wall 16, and the diversion holes 17 on the grille can introduce the flood water from the drainage holes 7 of the upper wall 5 into the cavity surrounded by the lower wall 4 and the side wall 16 to achieve the function of dynamic flood control and flood discharge.

[0099] The upper wall adopts a modular design, and each piece of the upper wall is connected by a mortise and tenon structure and fixed by a hydraulic rod and a pin, making the entire revetment structure more flexible and more adaptable to the flood control requirements of different water levels. When it is necessary to repair or replace the upper wall, only the damaged module needs to be replaced, without the need for large-scale disassembly and reconstruction of the entire revetment structure.

[0100] The flood control plate is connected to the side wall through a pulley and chain mechanism. The pulley is installed on the side wall. One end of the chain is connected to the flood control plate, and the other end is fixed to the side wall after passing around the pulley. By the brake, the chain is pulled to lift and lower the flood control plate.

[0101] The hydraulic rod fixing device includes an inverted convex chute arranged on the water-facing side of the upper wall, a pin installed in the chute, and a spring plate arranged below the pin. The spring plate can be automatically opened or closed to realize the fixing and position adjustment of the hydraulic rod in the chute.

[0102] During the dry season, the upper wall is horizontally lapped above the lower wall. Each upper wall is mortise-and-tenon connected to form a platform, which can be used for citizens' leisure and entertainment such as walking or fishing by the river.

[0103] During the flood season, when the water volume is not large enough, the upper wall still maintains a horizontal lap. Water can be introduced into the cavity through the flood control holes and drainage holes at the bottom of the upper wall. The position of the flood control board remains unchanged, and there is water on both sides of the lower wall, which can reduce the water pressure on the lower wall. The flood control board can also be lifted, and the water in the cavity flows into the municipal pipeline or the river ditch through the flood discharge holes, reducing the impact of floods.

[0104] As the water volume increases, the position of the upper wall can be adjusted according to the real-time flood water level. The upper wall is converted from horizontal to vertical by hydraulic drive to increase the water retaining height. According to the flood flow and velocity, the position of the flood control board is adjusted, and the flood control board is lifted and lowered through the pulley and chain mechanism to control the flood discharge volume.

[0105] Embodiment 12:

[0106] The main structure of this embodiment is the same as any one of Embodiments 1 to 11. Further, a modular hydraulic drive type revetment structure includes key components such as a foundation, an adjustable water retaining wall, side walls, and flood control boards.

[0107] The foundation is arranged along the entire length of the shore, and two rows of plum blossom-shaped anti-seepage curtains are arranged below to enhance its anti-seepage performance.

[0108] The adjustable water retaining wall is composed of a lower wall and an upper wall. The lower wall is connected to the foundation, and the upper wall is horizontally lapped above the lower wall, and flood control holes and drainage holes are provided at its bottom.

[0109] A chute is arranged on the water-facing side of the upper wall. Through the cooperation of a hydraulic rod and a pin, the upper wall can be flexibly converted from horizontal to vertical to adapt to different water level changes.

[0110] The bottom of the side wall is staggered with flood discharge holes and flood control boards. The flood control boards are lifted and lowered through a pulley and chain mechanism to control the flood flow.

[0111] In addition, a grille is arranged between the lower wall and the side wall. The diversion holes on the grille can introduce the flood water from the drainage holes of the upper wall into the cavity formed by the lower wall and the side wall, realizing the dynamic flood control and flood discharge function. Through modular design and hydraulic drive technology, the present invention realizes the dynamic adjustment and flood control and flood discharge function of the revetment structure, and has the advantages of stable structure, simple operation, good flood control effect, etc., and is applicable to the revetment projects of various rivers, lakes and other water bodies.
