Description

Technical Field

[0001] The present invention relates to the technical field of molds for revetment blocks, and particularly to a new type of coastal ecological wave-dissipating block capable of cultivating vegetation and its processing mold. Background Technique

[0002] The armor block is the main structure for bearing wave-breaking and energy dissipation in coastal protection projects, usually using natural stones or artificial concrete blocks. Compared with natural stones, artificial armor blocks such as the twisted X-block and the four-footed hollow block are easy to obtain and have high stability, and are widely used in actual projects. The seawalls and revetments with artificial block facings effectively achieve the safety functions of disaster prevention and erosion prevention, but their facades are monotonous, their appearances are rigid, the landscape effect is poor, and less consideration is given to the environmental impact, resulting in many ecological problems. With the continuous improvement of people's environmental protection awareness, it is of great significance to improve the ecological and landscape value on the basis of ensuring the safety functions of coastal protection projects.

[0003] At present, the construction of ecological coastal protection projects is mainly divided into two forms: one is to completely use natural structures and materials for coastal protection. For example, relying on natural vegetation such as mangroves or artificially cultivated bio-reefs as natural breakwaters has good ecological properties, but requires a larger construction space and a longer construction period; the other is to add ecological structures in the intertidal zone or the water-facing side in front of traditional protection projects to reduce the negative impact on the ecological environment. For example, adding caves (pits or gaps) to the armor structure to provide additional habitats, thereby improving biodiversity and richness, or combining vegetation with engineering structures, which can not only play a role in dissipating waves, but also create the habitat space required by organisms. This mixed design method reduces the construction cost and is also applicable to the ecological transformation of existing structures, so it is widely used in practice.

[0004] However, due to the usually complex wave dynamic conditions on the wave-facing slope, it is necessary to rely on the wave-breaking and energy-dissipating function of the armor units, which makes the ecological design and implementation of the wave-facing slope relatively conservative. On the basis of not weakening the wave-breaking function of the armor layer, the improvement of the ecological greening effect can be moderately pursued. Mohammad et al. proposed a new type of coastal ecological wave-dissipating armor unit that can cultivate vegetation, and evaluated the environmental protection and hydraulic performance of the new unit through laboratory and field tests. Le Xuan et al. summarized the lessons learned from the construction of typical coastal protection projects in the Mekong Delta of Vietnam, and proposed a multi-line defense solution of "sea dike / revetment + mangrove + offshore breakwater", in which vegetation greening was implemented on the wave-facing slope, improving the landscape effect. Chen et al. took the reclamation project of Taiping Bay in Dalian Port as an example to discuss the marine ecological protection and restoration plan. For the construction of the ecological sea dike, a slope structure was proposed, with rubble or fence panels as the slope protection materials, and saline-alkali plants such as shrubs and grasslands were planted to improve the ecology and landscape of the slope protection.

[0005] As can be seen from the above research, the ecological greening improvement of the armor layer of artificial units requires the units to have certain cavities or grooves for covering and planting greening plants or providing habitats for marine organisms. Based on the traditional four-legged hollow block, this application proposes a new type of ecological armor unit, and through physical model tests, analyzes the reflection coefficient and wave run-up of the unit on the slope breakwater, and at the same time explores the influence of the height of the upper frame of the unit on the wave-dissipating performance.

[0006] At the same time, the existing environmental protection revetment units need to be processed and manufactured through molds. By pouring concrete into the molds, the molds are disassembled after the environmental protection revetment units are formed for demolding operations. Most of the existing molds for environmental protection revetment units are fixed by the cooperation of bolts and nuts during assembly, requiring a large number of sets of bolts and nuts, and professional disassembly and assembly tools need to be used. This makes the disassembly and assembly process of the molds for environmental protection revetment units relatively cumbersome, not only affecting the demolding speed of the environmental protection revetment units, but also greatly reducing the processing efficiency of the environmental protection revetment units, which is not conducive to actual processing operations; after pouring concrete into the molds for environmental protection revetment units, the molds for environmental protection revetment units need to be vibrated to make the concrete in the molds more evenly distributed, and at the same time make the concrete arranged more closely together to improve the pouring quality of the environmental protection revetment units. However, the existing molds for environmental protection revetment units are prone to misalignment between the bottom mold, side mold, etc. during the vibration process, resulting in defects or damage to the poured environmental protection revetment units.

By rotating the second crank 71, the second crank 71 drives the bidirectional driving screw 7 to rotate. The bidirectional driving screw 7 drives the two clamping seats 72 to approach each other. When the clamping seats 72 move, they slide along the guiding slide plate 44, so that the clamping seats 72 can move stably. The two clamping seats 72 cooperate to clamp and fix the two side molds 22 in the assembling mold 2. When the two clamping seats 72 approach each other, they push the connecting rod 8 to rotate.

The other two side molds 22 in the assembling mold 2 are clamped and fixed by the two clamping seats 72. The assembling mold 2 is fixed by the cooperation of the lifting transmission mechanism and the limiting mechanism.

[0042] Working principle: When it is necessary to pour the revetment block, first drive the lifting transmission mechanism to move upward from the contraction groove 11 through the lifting drive mechanism. At this time, by rotating the second crank 71, the two clamping seats 72 are distributed away from each other at both ends of the bidirectional transmission screw 7. At this time, the bottom mold 21 is clamped at the upper end of the lifting seat 4, and then the four side molds 22 are vertically spliced at the upper end of the lifting seat 4. At the same time, the four side molds 22 are clamped on the side of the bottom mold 21, and the two side molds 22 are clamped inside the clamping plate 42. Then the four upper cover molds 25 are respectively covered on the upper ends of the four side molds 22, and the guide rods 24 on the side molds 22 are inserted into the round holes 26 on the upper cover molds 25 to accurately dock the upper cover molds 25 and the side molds 22. Then, through the cooperation of bolts and nuts, the four upper cover molds 25 are fixedly connected to complete the preliminary assembly of the assembled mold 2. By rotating the second crank 71, the second crank 71 drives the bidirectional transmission screw 7 to rotate, and the bidirectional transmission screw 7 drives the two clamping seats 72 to approach each other. Through the cooperation of the two clamping seats 72, the two side molds 22 in the assembled mold 2 are clamped and fixed. When the two clamping seats 72 approach each other, they push the connecting rod 8 to rotate, and the connecting rod 8 pushes the convex block 81 to slide along the lifting seat 4, so that the two convex blocks 81 are distributed away from each other. At the same time, the convex block 81 drives the insertion rod 82 to insert into the jacks 23 of the bottom mold 21 and the side mold 22, so that the bottom mold 21 and the side mold 22 are fixedly connected. At the same time, when the clamping seat 72 moves, it drives the fixed plate 73 and the L-shaped limiting plate 74 to move, so that the fixed plate 73 is clamped on the side of the assembled mold 2, and the L-shaped limiting plate 74 is clamped on the upper end of the assembled mold 2, so as to further fix the assembled mold 2 and prevent the bottom mold 21 and the side mold 22 from loosening or misaligning when the assembled mold 2 vibrates. At this time, the PPR pipe is inserted on the bottom mold 21, and the inner cavity of the assembled mold 2 is poured with concrete. Then the top mold 27 is installed in the inner cavity of the assembled mold 2. Pull the handle 6 upward, the handle 6 drives the positioning rod 61 to slide upward along the vertical plate 5, and the positioning rod 61 drives the pressing plate 62 to press the positioning spring 63. Then the L-shaped support rod 28 is inserted into the card slot 51, and then the handle 6 is released. Under the action of the elastic force of the positioning spring 63, the positioning rod 61 moves downward, and the lower end of the positioning rod 61 is inserted into the positioning hole on the L-shaped support rod 28, so that the L-shaped support rod 28 is fixedly connected to the vertical plate 5, and then the fixation of the top mold 27 is completed, and the top mold 27 is fixed on the assembled mold 2;By rotating the first crank 31, the circular shaft 3 is driven to rotate. The circular shaft 3 drives the two transmission bevel gears 32 to rotate. The two transmission bevel gears 32 drive the two synchronous bevel gears 33 to rotate. The two synchronous bevel gears 33 drive the two lifting studs 34 to rotate. When the lifting studs 34 rotate, they drive the lifting transmission block 43 to move up and down. The lifting transmission block 43 stably slides up and down along the lifting chute 12. At the same time, the lifting transmission block 43 drives the lifting seat 4 to slide down along the contraction groove 11. The lifting seat 4 drives the assembly mold 2 to move downwards, so that the assembly mold 2 is clamped into the contraction groove 11, thereby further fixing the assembly mold 2. Then, concrete is poured into the upper layer of the assembly mold 2. Through the cooperation of the fixed seat 1, the lifting transmission mechanism and the limiting mechanism, the assembly mold 2 is clamped and fixed, preventing loosening or misalignment between the bottom mold 21 and the side mold 22 during the vibration process, so that the cast revetment blocks can solidify well together; when the cast revetment blocks need to be demolded after solidifying, the lifting transmission mechanism is driven by the lifting drive mechanism to move upwards out of the contraction groove 11, so that the assembly mold 2 and the revetment blocks move upwards. Then, the two clamping seats 72 in the limiting mechanism move away from each other, loosening the fixation of the limiting mechanism on the assembly mold 2. At this time, the upper cover mold 25 can be moved upwards to separate the upper cover mold 25 from the side mold 22. At the same time, the upper cover mold 25 drives the top mold 27 to move upwards. Then, the four side molds 22 are disassembled from the side of the revetment blocks. At this time, the revetment blocks can be conveniently taken out, and then the demolding operation of the revetment blocks is completed. The assembly and disassembly of the assembly mold 2 and the top mold 27 are simple and convenient, greatly improving the work efficiency.
