[0038] S40: installing the first wave-breaking inclined steel plate obliquely on the inclined frame along the outer side of each set of peripheral steel frames, and installing the first wave-breaking concrete wall corresponding to the first wave-breaking inclined steel plate in each set of peripheral steel frames;

When the shock wave acts on the middle position of the secondary wave-absorbing rotatable wave-absorbing wall, the secondary wave-absorbing rotatable wave-absorbing wall does not rotate, and the shock wave propagates to both sides at this time. The shock wave is constantly reflected and refracted between the secondary wave-absorbing fixed wave-absorbing walls arranged on both sides to perform wave-absorbing and energy-consuming, and the remaining shock wave is finally discharged upward through reflection to achieve the effect of wave-absorbing and energy-consuming; when the shock wave acts on one side or both sides of the secondary wave-absorbing rotatable wave-absorbing wall, the secondary wave-absorbing rotatable wave-absorbing wall rotates, and the shock wave propagates to one side at this time, that is, it is passed through one group of the secondary wave-absorbing fixed wave-absorbing walls to perform wave-absorbing and energy-consuming in the same way, thereby protecting the other side, and finally the remaining shock wave is discharged upward to one side to achieve the effect of wave-absorbing and energy-consuming.

[0073] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in conjunction with the embodiments and drawings. Here, the illustrative embodiments of the present invention and their description are used to explain the present invention, but are not intended to limit the present invention.

[0074] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0075] It should be understood that the terms "include / comprise", "consist of..." or any other variations are intended to cover non-exclusive inclusion, so that a product, device, process or method that includes a series of elements includes not only those elements, but also may include other elements not explicitly listed when necessary, or also includes elements inherent to such product, device, process or method. In the absence of more restrictions, the elements defined by the sentence "include / comprise...", "consist of..." do not exclude the presence of other identical elements in the product, device, process or method that includes the elements.

[0076] It is also necessary to understand that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" to indicate directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device, component or structure must have a specific direction, be constructed or operate in a specific direction, and should not be understood as a limitation on the present invention.

[0077] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0078] The implementation of the present invention is described in detail below in conjunction with preferred embodiments.

[0079] like Figures 1 to 6C As shown, the present invention proposes an assembled multi-stage wave-breaking and explosion-proof dike. The multi-stage wave-breaking and explosion-proof dike is composed of an outer steel frame 1, a primary wave-breaking structure 2, a secondary wave-breaking structure 3, and earth and sand bags 4. The present invention can be used at a certain distance from the place where pyrotechnics are stored to vent explosions to ensure the safety of the staff in the control room behind the explosion-proof dike. It can also be used for wartime explosion resistance to facilitate the protection of buildings and personnel safety during field operations or military explosion tests.

[0080] See also Figures 1 to 4 The outer steel frame 1 is a frame structure, which has an internal space. The outer steel frame 1 is provided with four, and the four outer steel frames 1 enclose a terrace-like structure with four outer surfaces inclined upward and inward and a central accommodating cavity 5 in the middle.

[0081] In the present invention, the trapezoidal structure of the peripheral steel frame 1 has excellent bending and shear resistance. When the four peripheral steel frames 1 enclose a terrace-like structure with four outer sides tilted upward and inward and a central accommodating cavity 5 in the middle, the entire explosion-proof dike has stable support in four directions. This design enables the explosion-proof dike to better resist external forces such as explosion shock waves and wind from all directions, thereby improving the overall explosion-proof performance.

[0082] In some embodiments, see Figure 3 Each set of peripheral steel frames 1 is connected by bolts through connecting beams 101, vertical steel columns 102 and corner connectors 103. It is easy to understand that the peripheral steel frames 1 constitute the overall framework of the primary wave-breaking structure 2, which is used to accommodate the primary wave-breaking structure 2.

[0083] The modules of the peripheral steel frame 1 can be prefabricated in the factory and quickly assembled on site. This construction method greatly shortens the construction period and improves construction efficiency. Due to the bolt connection method, the modules of the peripheral steel frame 1 can be easily adjusted and corrected. This helps to ensure the accuracy and stability of the entire structure and improve the construction quality.

[0084] In some embodiments, the top and bottom of the vertical steel column 102 are both provided with an E-shaped plug-in interface, which is suitable for directly inserting into the connection part of one of the connecting beams 101 after the adjacent corner connecting beams 101 are bolted together, thereby reducing the complex welding or additional fixing steps that may be required in the traditional connection method, thereby simplifying the installation process.

[0085] In some embodiments, the cross-section of each set of peripheral steel frames 1 is a right-angled trapezoid, thereby forming a right-angled ladder mechanism, which can remain stable after being placed.

[0086] Continue to see Figure 3 to Figure 4 The primary wave-breaking structure 2 includes a primary wave-breaking inclined steel plate 201 and a primary wave-breaking concrete wall 202. The primary wave-breaking inclined steel plate 201 is obliquely installed on an inclined frame arranged along one side of the outside of each set of peripheral steel frames 1, and the primary wave-breaking concrete wall 202 is installed in the peripheral steel frame 1 opposite to the primary wave-breaking inclined steel plate 201.

[0087] In the present invention, the first-level wave-breaking inclined steel plate 201 is used as the first line of defense of the first-level wave-breaking structure 2 to resist the first impact of the explosion shock wave. When the first-level wave-breaking inclined steel plate 201 is impacted by the shock wave, it will undergo certain deformation and vibration, which will consume the energy of the shock wave. At the same time, the first-level wave-breaking inclined steel plate 201 can guide the direction of the explosion shock wave upward and downward, reducing its direct impact on the outer steel frame 1. The first-level wave-breaking concrete wall 202 is used as the second line of defense of the first-level wave-breaking structure 2, which can effectively reduce the energy and propagation direction of the explosion shock wave. More specifically, its internal cavity structure can absorb and disperse the energy of the explosion shock wave, and through multiple reflections and refractions, effectively reduce the energy density of the shock wave, and further weaken its impact force.

[0088] In some embodiments, a slide groove (not shown in the figure) is reserved on the inclined frame arranged along the outer side of each group of peripheral steel frames 1. The width of the slide groove is the same as the thickness of the first-level wave-breaking inclined steel plate 201, which is suitable for plugging and fixing the first-level wave-breaking inclined steel plate 201.

[0089] In a specific embodiment, a sliding groove is left on the side of the corner connector 103 of the outer steel frame 1, and the first-level wave-breaking inclined steel plate 201 is inserted into the sliding groove.

[0090] In some embodiments, see Figure 4 The first-level wave-breaking inclined steel plate 201 includes a steel plate body 2011 and wave-breaking ribs. The steel plate body 2011 is obliquely clamped and fixed in an inclined frame arranged along one side of each set of peripheral steel frames 1.

[0091] The wave-breaking ribs are arranged in an interlaced manner, including multiple groups of first wave-breaking ribs 2012 and multiple groups of second wave-breaking ribs 2013. Multiple groups of first wave-breaking ribs 2012 and multiple groups of second wave-breaking ribs 2013 are arranged in an interlaced manner on the outer surface of the steel plate body 2011, and each group of first wave-breaking ribs 2012 is arranged along the inclined surface of the steel plate body 2011, and each group of second wave-breaking ribs 2013 is arranged discontinuously along the inclined surface of the steel plate body 2011. The shock wave is eliminated upward and downward through these two ribs.

[0092] In the present invention, the first wave-breaking ribs 2012 are continuously arranged along the inclined surface of the steel plate body 2011 to form a path for guiding the propagation of shock waves. When the shock waves contact these ribs, they will be guided to propagate along the direction of the ribs, thereby increasing the contact area and time between the shock waves and the steel plate. In this process, the energy of the shock waves will be gradually absorbed and dissipated by the ribs. The second wave-breaking ribs 2013 are arranged at certain intervals on the steel plate. This intermittent arrangement makes the shock waves constantly encounter obstacles and change directions during the propagation process, thereby increasing the chance of energy dissipation.

[0093] More specifically, when the shock wave contacts the steel plate body 2011, it will first interact with the first wave-breaking ribs 2012. These ribs will guide the shock wave to propagate upward or downward along the inclined surface while gradually dissipating its energy. Subsequently, the shock wave will encounter the second wave-breaking ribs 2013, which will further hinder the propagation of the shock wave and increase energy dissipation. Through the combined action of these two ribs, the energy of the shock wave will be effectively absorbed and dissipated, thereby reducing its damage to the surrounding environment and structure.

[0094] In some embodiments, each group of first wave-breaking ribs 2012 includes a full-length stiffening steel plate, which is welded and fixed vertically to the surface of the steel plate body 2011 .

[0095] In some embodiments, each group of second wave-breaking ribs 2013 includes at least two intermittently arranged stiffening steel plates, and the two intermittently arranged stiffening steel plates are vertically welded and fixed to the surface of the steel plate body 2011 .

[0096] Continue to see Figure 3 , Figure 4 The first-level wave-breaking concrete wall 202 is fixedly installed in the inner frame of each group of peripheral steel frames 1. The top of the first-level wave-breaking concrete wall 202 is fixedly connected with the top outer frame of each group of peripheral steel frames 1.

[0097] Alternatively, a concrete foundation is cast at the bottom of the primary wave-breaking concrete wall 202, and is fixed to the ground through the concrete foundation. Specifically, the concrete foundation can be directly fixed by embedding it in the soil, or by casting concrete to fix it.

[0098] Of course, the bottom fixing method of the primary wave-breaking concrete wall 202 is not limited to the cast concrete foundation. Another feasible method is to set plug-in nails, which can be directly anchored into the soil to provide stable support. The present design does not limit the specific fixing method, as long as it can ensure that the primary wave-breaking concrete wall 202 is firmly installed inside each set of peripheral steel frames 1. Such a design is highly flexible and can adapt to different construction conditions and requirements.

[0099] Continue to see Figure 3 , Figure 4 The primary wave-breaking concrete wall 202 is a concrete wall with multiple cylindrical cavities 2021 formed inside. The multiple cylindrical cavities 2021 penetrate along the thickness direction of the concrete wall and are evenly arranged along the width and height directions. When the shock wave breaks through the primary wave-breaking inclined steel plate 201 and starts to impact the primary wave-breaking concrete wall 202, the explosion shock wave will undergo continuous reflection, diffraction, Mach reflection and other complex reflections when passing through the multiple cylindrical cavities 2021. The explosion shock wave can be further attenuated in the multiple cylindrical cavities 2021.

[0100] In the present invention, the first-level wave-breaking concrete wall 202 is made of high-strength concrete of C40 or higher. During production, a mold is prefabricated in advance, concrete is poured into the mold, and the corresponding first-level wave-breaking concrete wall 202 is obtained after the mold is removed.

[0101] Continue to see Figure 1 to Figure 2 The secondary wave-absorbing structure 3 specifically includes a group of secondary wave-absorbing rotatable wave-absorbing walls 301 and four groups of secondary wave-absorbing fixed wave-absorbing walls 302. The secondary wave-absorbing rotatable wave-absorbing wall 301 is arranged in the middle of the middle accommodating chamber 5, and the four groups of secondary wave-absorbing fixed wave-absorbing walls 302 are symmetrically arranged in front, behind, left and right of the secondary wave-absorbing rotatable wave-absorbing wall 301. Through such an arrangement, the angle can be enlarged by rotating the middle wall, and the shock wave can be guided out from both sides, while playing a buffering role. However, if the shock wave is too large, the traditional middle wall is fixed, and the wall will be directly destroyed and fly backwards, causing harm to the people behind.

[0102] In the present invention, the secondary wave-absorbing rotatable wave-absorbing wall 301 and the secondary wave-absorbing fixed wave-absorbing wall 302 serve as a secondary wave-absorbing structure. When a shock wave acts on the middle position of the secondary wave-absorbing rotatable wave-absorbing wall 301 of the secondary wave-absorbing structure, the secondary wave-absorbing rotatable wave-absorbing wall does not rotate. At this time, the shock wave propagates to both sides. The shock wave is continuously reflected and refracted between the secondary wave-absorbing fixed wave-absorbing walls 302 arranged on both sides to perform wave-absorbing and energy-consuming. The remaining shock wave is finally discharged upward through emission to achieve the effect of wave-absorbing and energy-consuming. When the shock wave acts on both sides of the secondary wave-absorbing rotatable wave-absorbing wall 301, the secondary wave-absorbing rotatable wave-absorbing wall 301 rotates. At this time, the shock wave propagates to one side, that is, through one group of the secondary wave-absorbing fixed wave-absorbing walls 302, wave-absorbing and energy-consuming are performed in the same way, thereby protecting the other side. Finally, the remaining shock wave is discharged upward on one side to achieve the effect of wave-absorbing and energy-consuming.

[0103] The present invention uses the primary wave-breaking structure 2 and the secondary wave-breaking structure 3 to jointly resist the impact of the explosion shock wave, and plays a good wave-breaking effect. In actual arrangement, the secondary wave-breaking rotatable wave-breaking wall 301 and the secondary wave-breaking fixed wave-breaking wall 302 are preferably arranged in the middle accommodating cavity facing the explosion direction, so as to achieve two-stage wave-breaking and explosion-proof. However, it can also be arranged at will in some non-important occasions, for example, the wall surface is at a certain angle to the explosion direction, or even in the same direction as the explosion direction. At this time, the secondary wave-breaking can also play a role in dispersing the shock wave to a certain extent, but the effect is worse than the front, and the primary wave-breaking mainly plays a role.

[0104] It is easy to understand that the present invention sets the direction facing the place where the explosives are stored or the structure or personnel to be protected as the explosion direction.

[0105] In some embodiments, see FIG. 5A to FIG. 5DEach set of secondary wave-absorbing rotatable wave-absorbing walls 301 is composed of rectangular concrete blocks 6, channel steel plates 7 (U-shaped steel plates), lateral baffles 8, prestressed reinforcement bars 9 and rotating components 11.

[0106] Specifically, there are multiple rectangular concrete blocks 6, which are stacked in the vertical direction, for example, three, and a through vertical plug hole 601 is opened in the middle of the multiple rectangular concrete blocks 6. By stacking multiple blocks, it is easy to assemble and disassemble, and it can also avoid the problem that a single full-length concrete wall has poor tensile and bending properties and is prone to brittle failure.

[0107] There are multiple channel steel plates 7, two per group, and each group is symmetrically arranged at the front and back of each rectangular concrete block 6. The web of each group of channel steel plates 7 is in close contact with the surface of the rectangular concrete block 6, and multiple prestressed tendon holes 701 are symmetrically arranged on the two flanges to facilitate the installation of prestressed tendons 9. The channel steel plate is used as a part of the wall panel to overcome the defect of poor bending resistance of the simple concrete structure.

[0108] There are multiple lateral baffles 8, two in each group, each group is symmetrically arranged on the left and right sides of each rectangular concrete block 6, and is welded and fixed to the webs of two channel steel plates 7 arranged along the front and rear sides of each rectangular concrete block 6. The lateral baffles 8 mainly play the role of connecting and fixing the rectangular concrete block 6 and the channel steel plate 7, ensuring that the connection between the rectangular concrete block 6 and the channel steel plate 7 is more stable.

[0109] There are multiple prestressed tendons 9, each of which vertically penetrates multiple prestressed tendon holes 701 of multiple groups of channel steel plates 7 to connect multiple rectangular concrete blocks 6. Since multiple wall blocks are vertically stacked together, their bending resistance is relatively weak, and they are further connected into a whole with the help of prestressed tendons to enhance the toughness and bending resistance of the wall.

[0110] The bottom of the rotating assembly 11 is suitable for fixing with the soil, and the top is suitable for inserting into the vertical plug hole 601 to drive the plurality of rectangular concrete blocks 6 to rotate. The design of the rotating assembly 11 enables the secondary wave-breaking rotatable wave-breaking wall 301 to rotate to a certain extent when subjected to the explosion shock wave. This rotation not only helps to disperse and absorb the energy of the shock wave, but also can reduce its direct impact on the protected target by changing the propagation direction of the shock wave.

[0111] In a specific embodiment, the rotating assembly 11 includes a first foundation 111, a steel column rotating shaft 112, and a fixed turntable 113. The first foundation 111 is the supporting structure of the entire rotating assembly 11, and its main function is to be buried in the soil for fixing, providing stable support and positioning for the entire assembly. The first foundation 111 is usually made of high-strength and durable materials such as concrete or reinforced concrete to ensure that it can withstand various loads from the secondary wave-breaking rotatable wave-breaking wall 301 and the external environment.

[0112] The first foundation 111 is cylindrical and is buried in the soil through construction steps such as digging a foundation pit and pouring concrete, and is subjected to sufficient curing time to ensure its close combination with the surrounding soil and stability.

[0113] The bottom of the steel column rotating shaft 112 is rotatably connected to the first foundation 111, and the top is suitable for inserting into the vertical plug hole 601. In the present invention, the steel column rotating shaft 112 is a key component connecting the first foundation 111 and the secondary wave-breaking rotatable wave-breaking wall 301, which allows the secondary wave-breaking rotatable wave-breaking wall 301 to rotate around its axis within a certain range. The steel column rotating shaft 112 is usually made of high-strength steel to ensure that it can withstand loads such as torque and bending moment from the secondary wave-breaking rotatable wave-breaking wall 301.

[0114] It is easy to understand that the bottom of the steel column rotating shaft 112 is rotatably connected to the first foundation 111, which is usually achieved through rotating parts such as bearings and sleeves to ensure the flexibility and stability of rotation. The top is suitable for inserting into the vertical plug hole 601 to form a connection with the secondary wave-breaking rotatable wave-breaking wall 301.

[0115] The fixed turntable 113 is sleeved on the steel column rotating shaft 112 and rigidly connected to the steel column rotating shaft 112; a plurality of bolt holes are provided on the fixed turntable 113, which is suitable for being connected and fixed to the bottom of the secondary wave-breaking rotatable wave-breaking wall 301 through bolts 10.

[0116] It is easy to understand that the rigid connection here can be achieved by respectively setting keyways and keys on the fixed turntable 113 and the steel column rotating shaft 112 to achieve circumferential fixation between the two; or bolt connection or welding connection or other methods that can achieve fixed connection.

[0117] The fixed turntable 113 is a transition component connecting the steel column rotating shaft 112 and the secondary wave-breaking rotatable wave-breaking wall 301. It transmits the rotation of the steel column rotating shaft 112 to the secondary wave-breaking rotatable wave-breaking wall 301 and provides stable support for it. The fixed turntable 113 is also made of high-strength steel to ensure that it can withstand the load from the secondary wave-breaking rotatable wave-breaking wall 301 and maintain the integrity of the structure.

[0118] In the present invention, the rotating assembly 11 realizes the stable rotation and fixation of the secondary wave-breaking rotatable wave-breaking wall 301 through the coordinated action of the first foundation 111, the steel column rotating shaft 112, the fixed rotating disk 113 and the bolts 10. This structure not only has the advantages of high strength and good durability, but also can adjust the inclination angle of the secondary wave-breaking rotatable wave-breaking wall 301 according to actual needs to adapt to different explosion scenes and protection requirements.

[0119] In some embodiments, see FIG. 6A to FIG. 6C Each set of secondary wave-breaking fixed wave-breaking walls 302 is composed of L-shaped concrete blocks 12, channel steel plates 7, lateral baffles 8 and prestressed reinforcement bars 9.

[0120] Specifically, a plurality of L-shaped concrete blocks 12 are provided, and each group of two L-shaped concrete blocks 12 are staggered and spliced ​​into rectangular blocks in the horizontal direction, and a plurality of rectangular blocks are stacked in the vertical direction. By designing the L-shaped concrete block structure, after two L-shaped concrete blocks are staggered and spliced ​​into rectangular blocks in the horizontal direction, an L-shaped (folded) gap is formed at the staggered position, and this shape is beneficial to improving the wave-breaking effect.

[0121] In the present invention, two L-shaped concrete blocks 12 are staggered horizontally and multiple groups of L-shaped concrete blocks 12 are stacked vertically, thus forming a horizontal and vertical staggered arrangement, which can not only allow the shock wave to be diverted along the L shape, but also the energy of the shock wave can be better dissipated under this arrangement.

[0122] There are multiple channel steel plates 7, each two in a group, and each group is symmetrically arranged at the front and back of each rectangular block. The web of each group of channel steel plates 7 is in close contact with the surface of the rectangular block, and multiple prestressed tendon holes 701 are symmetrically arranged on the two flanges to facilitate the installation of prestressed tendons 9.

[0123] There are multiple lateral baffles 8, two in each group, each group is symmetrically arranged on the left and right sides of each rectangular block (two L-shaped concrete blocks 12 in each group), and are welded and fixed to the webs of two channel steel plates 7 arranged along the front and rear sides of each group of L-shaped concrete blocks 12. The lateral baffles 8 mainly play the role of connecting and fixing the L-shaped concrete blocks 12 and the channel steel plates 7, ensuring that the connection between the L-shaped concrete blocks 12 and the channel steel plates 7 is more stable.

[0124] There are multiple prestressed tie bars 9, and each prestressed tie bar 9 passes through multiple prestressed tie bar holes 701 of multiple groups of channel steel plates 7 in the vertical direction to connect multiple rectangular blocks together. They can also be connected into a whole with the help of prestressed tie bars to enhance the toughness and bending resistance of the wall.

[0125] In some embodiments, a second foundation 13 is cast at the bottom of each set of secondary wave-breaking fixed wave-breaking walls 302, and is fixed to the ground through the second foundation 13. Specifically, the second foundation 13 can be directly fixed by embedding it in the soil, or fixed by pouring concrete.

[0126] The second foundation 13 is usually made of high-strength and durable materials such as concrete or reinforced concrete.

[0127] The second foundation 13 is in a terraced shape. The terraced foundation design can increase the contact area with the ground, thereby improving the stability of the entire structure.

[0128] In some embodiments, see Figure 1 , Figure 2 The present invention is also provided with a soil and sand bag 4, which is filled in the corner gap between two adjacent peripheral steel frames 1. The soil and sand bag can play an anti-explosion role at the corner, and at the same time play a role in connecting and fixing the two adjacent peripheral steel frames 1. The sand bag has good anti-explosion performance and is commonly used in traditional anti-explosion dikes. Here, the sand bag is used to fix and connect the two adjacent steel frames on the one hand, and on the other hand, it has a good anti-explosion effect.

[0129] In the present invention, the primary wave-absorbing structure 2 and the secondary wave-absorbing structure 3 jointly resist the impact of the explosion shock wave. When an explosion occurs, the explosion shock wave first acts on the primary wave-absorbing structure 2. The primary wave-absorbing inclined steel plate 201 of the primary wave-absorbing structure 2 first absorbs the wave and reflects the explosion shock wave upward. When the shock wave breaks through the primary wave-absorbing inclined steel plate 201, it begins to impact the primary wave-absorbing concrete wall 202. When the explosion shock wave passes through the cavity, continuous reflection, diffraction, and Mach reflection and other complex reflections will occur. The explosion shock wave can be further absorbed in the cavity; then the shock wave passing through the cavity concrete wall 202 is absorbed by the secondary wave-absorbing structure 3. The secondary wave-absorbing structure 3 is absorbed by the secondary wave-absorbing rotatable wave-absorbing wall 301 and the secondary wave-absorbing fixed wave-absorbing wall 302. The secondary wave-absorbing rotatable wave-absorbing wall 301 of the secondary wave-absorbing structure 3 is placed in the middle, and the secondary wave-absorbing fixed wave-absorbing wall 302 is placed in the middle. The fixed wave-breaking walls 302 are placed at the four corners on both sides, and the above-mentioned walls are staggered. When the shock wave acts on the middle position of the secondary wave-breaking rotatable wave-breaking wall 301 of the secondary wave-breaking structure 3, the secondary wave-breaking rotatable wave-breaking wall 301 does not rotate. At this time, the shock wave propagates to both sides, and is finally discharged upward through emission to achieve the effect of wave-breaking energy consumption. When the shock wave acts on one side or both sides of the secondary wave-breaking rotatable wave-breaking wall 301 of the secondary wave-breaking structure 3, the secondary wave-breaking rotatable wave-breaking wall 301 rotates. At this time, the shock wave propagates to one side, and a group of secondary wave-breaking fixed wave-breaking walls 302 on this side are used to dissipate waves and consume energy in the same way, thereby protecting the other side. Finally, the shock wave is discharged upward on one side to achieve the effect of wave-breaking energy consumption.

[0130] The present invention also proposes a method for installing the above-mentioned assembled multi-stage wave-breaking and explosion-resistant dike, see Figure 7 , specifically including the following steps:

[0131] S10: prefabricate the outer steel frame 1, the primary wave-breaking inclined steel plate 201 and the primary wave-breaking concrete wall 202 of the primary wave-breaking structure 2, the secondary wave-breaking rotatable wave-breaking wall 301 and the secondary wave-breaking fixed wave-breaking wall 302 of the secondary wave-breaking structure 3, and the earth and sand bags 4 in the factory in advance;

[0132] S20: At the construction site, four peripheral steel frames 1 are enclosed to form a terrace-like structure with four inclined outer sides and a central accommodation cavity 5 in the middle;

[0133] S30: installing the secondary wave-absorbing rotatable wave-absorbing wall 301 and the secondary wave-absorbing fixed wave-absorbing wall 302 in the middle accommodating chamber 5 in a predetermined manner;

[0134] S40: installing the primary wave-breaking inclined steel plate 201 obliquely on an inclined frame arranged along one side of the outside of each set of peripheral steel frames 1, and installing the primary wave-breaking concrete wall 202 in each set of peripheral steel frames 1 opposite to the primary wave-breaking inclined steel plate 201;

[0135] S50: placing earth and sand bags 4 at the corners of two adjacent outer steel frames 1 to connect and fix the two adjacent outer steel frames 1 .

[0136] In some embodiments, in S30, a secondary wave-absorbing rotatable wave-absorbing wall is arranged in the middle of the middle accommodating cavity along the first direction, and four secondary wave-absorbing fixed wave-absorbing walls are arranged symmetrically in front, behind, left and right of the secondary wave-absorbing rotatable wave-absorbing wall along the first direction.

[0137] The assembly-type explosion-proof dike installation method of the present invention has multiple advantages, such as factory prefabrication to improve construction efficiency, convenient on-site assembly to reduce construction difficulty, multi-level wave-breaking design to improve protection capability, and improved engineering quality to reduce maintenance costs. This method not only improves construction efficiency and quality, but also reduces construction difficulty and maintenance costs, providing a new solution for the construction of explosion-proof dikes.

[0138] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0139] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
