Description

Technical Field

[0001] The invention relates to a starfish-shaped wave-breaking, wave-proof and landing-proof concrete block and a manufacturing method thereof. Background Art

[0002] Coastal erosion refers to the process in which the expenditure of marine sediment exceeds the input and the sediment is lost due to the action of natural forces (including wind, waves, currents and tides). That is, the impact of seawater dynamics causes the retreat of the coastline and the erosion of the beach. Coastal erosion is a common phenomenon, and it exists on about 70% of sandy coastlines and almost all open muddy coastlines.

[0003] The artificial coral reef island is built with coral sand. The foundation of the island reef revetment has been subjected to scouring and erosion by ocean tides for a long time, posing a great safety hazard. In order to prevent the erosion and damage of the island reef foundation and the revetment by wave scouring, a large number of twisted king-shaped blocks are arranged on the reef flats outside the revetment. However, these twisted king-shaped blocks are large in size, high in cost, and have unsatisfactory wave-breaking effects. When the waves scour the mud and sand at the bottom of the twisted king-shaped blocks, they are prone to collapse and rolling. Summary of the invention

[0004] The main purpose of the present invention is to provide a starfish-shaped wave-breaking, wave-proof and landing-proof concrete block and a manufacturing method thereof, so as to achieve a simple, effective, low-cost, wave-breaking and wave-proof effect.

[0005] To achieve the above-mentioned purpose, the present invention provides a starfish-shaped wave-breaking and anti-landing concrete block, comprising a starfish-shaped chassis, three horns are evenly arranged on the upper part of the starfish-shaped chassis, and the axes of the horns intersect at one point; the bottom surface of the starfish-shaped chassis is a five-pointed star; one end of the three horns converges on the starfish-shaped chassis, and the other end extends outward and tilts along the central axis of the starfish-shaped chassis.

[0006] Furthermore, the horns are cylindrical or conical, and the bottom surface of the starfish-shaped chassis has an uneven structure.

[0007] Furthermore, the angle between the axis of the horn and the starfish-shaped chassis is 35-60 degrees.

[0008] Furthermore, the starfish-shaped chassis and three horns are an integrated structure cast in concrete, weighing 5-10 tons.

[0009] Furthermore, the horn and / or starfish-shaped chassis is hollow.

[0010] Furthermore, the horn and / or starfish-shaped chassis is filled with construction waste.

[0011] Furthermore, steel nail thorns are arranged on the upper part of the chassis and the horns.

[0012] The present invention also provides a method for manufacturing a starfish-shaped wave-breaking, wave-proof and landing-proof concrete block, comprising the following steps:

[0013] S10, prepare the mold and assemble it;

[0014] S20, pouring cement slurry made of 425 silicate cement into the assembled mold, vibrating, compacting, and sealing the mold;

[0015] S30, curing for 3-7 days, concrete strength test, concrete strength grade is C40, mechanical mold opening is carried out after the strength is qualified;

[0016] S40, after natural drying for 1-2 days, the injection port is sealed with cement slurry made of 425 silicate cement;

[0017] S50, after 1-2 days of natural drying, the correction is complete.

[0018] Furthermore, the mold is a hollow mold, and S31 is provided between S30 and S40: pouring construction waste slurry into the cast concrete block.

[0019] Furthermore, the garbage slurry is mixed with an accelerating setting agent and a preservative.

[0020] The present invention is simple, effective and low in cost. The concrete blocks described in the present invention are arranged on the reef flats outside the beach and coral reef revetment, and have the functions of wave protection and wave absorption, so as to weaken the impact of waves on the revetment and dock structures. Due to the pentagonal starfish-shaped chassis structure, multiple concrete blocks can be arranged regularly by using complementary corners, or they can be arranged irregularly. Moreover, the pentagonal star-shaped structure has a more stable grip, and even if the waves destroy the sand and gravel layer underneath, the stay time can still be effectively extended. When considering the defense function, steel spikes and thorns like sea urchins can be set on the upper part of the starfish-shaped chassis and the horns to achieve the function of blocking and defending against the landing of small boats, tanks and personnel.

[0025] In order to achieve the above-mentioned purpose and effect, the technical means and structures adopted by the present invention are described in detail with reference to the accompanying drawings for the features and functions of the preferred embodiments of the present invention.

[0026] like Figure 1-3 As shown, the present invention provides a starfish-shaped wave-breaking and anti-landing concrete block, comprising a starfish-shaped chassis 1, three horns 2 are evenly arranged on the upper part of the starfish-shaped chassis 1, and the axes of the horns 2 intersect at one point; the bottom surface of the starfish-shaped chassis 1 is a five-pointed star; one end of the three horns 2 converges on the starfish-shaped chassis 1, and the other end extends outward along the central axis of the starfish-shaped chassis 1 and tilts.

[0027] The horn 2 is cylindrical or conical, and the bottom surface of the starfish-shaped chassis 1 has an uneven structure.

[0028] The included angle between the axis of the horn 2 and the starfish-shaped chassis 1 is 35-60 degrees.

[0029] The starfish-shaped chassis and the three horns 2 are an integrated structure cast in concrete and weigh 5-10 tons.

[0030] The horns 2 and / or the starfish-shaped chassis 1 are hollow.

[0031] The horns 2 and / or the starfish-shaped chassis 1 are filled with construction waste.

[0032] Steel nail thorns are arranged on the upper part of the chassis 1 and the horns 2 .

[0033] The present invention is simple, effective and low in cost. The concrete blocks described in the present invention are arranged on the reef flats outside the beach and coral reef revetment, and have the functions of wave protection and wave absorption, so as to weaken the impact of waves on the revetment and dock structures. Due to the pentagonal starfish-shaped chassis structure, multiple concrete blocks can be arranged regularly by using complementary corners, or they can be arranged irregularly. Moreover, the pentagonal star-shaped structure has a more stable grip, and even if the waves destroy the underlying sand and gravel layer, the stay time can still be effectively extended. When considering the defense function, steel spikes and thorns like sea urchins can be set on the upper part of the starfish-shaped chassis and the horns to achieve the function of blocking and defending against the landing of small boats, tanks and personnel.

[0034] The invention can be arranged and placed on the slope of the breakwater to prevent and dissipate waves.

[0035] As another embodiment, the present invention also provides a method for manufacturing a starfish-shaped wave-breaking, wave-proof and landing-proof concrete block, comprising the following steps:

[0036] S10, prepare the mold and assemble it;

[0037] S20, pouring cement slurry made of 425 silicate cement into the assembled mold, vibrating, compacting, and sealing the mold;

[0038] S30, curing for 3-7 days, concrete strength test, concrete strength grade is C40, mechanical mold opening is carried out after the strength is qualified;

[0039] S40, after natural drying for 1-2 days, the injection port is sealed with cement slurry made of 425 silicate cement;

[0040] S50, after 1-2 days of natural drying, the correction is complete.

[0041] The mold is a hollow mold, and S31 is further provided between S30 and S40: pouring construction waste slurry into the poured concrete block.

[0042] The garbage slurry is mixed with an accelerating setting agent and a preservative.

[0043] In addition, an anti-scour protection layer may be provided on the side surface and the upper surface of the entire structure.

[0044] The present invention is applicable to all revetment peripheral structures, islands and other special environments; it utilizes the reflection and diffraction caused by waves on the horns and the internal turbulence of the fluid between the horns to change the wave transmission mode, dissipate wave energy, and play a role in wave prevention and wave absorption.

[0045] Compared with the traditional pile group structure, the ox horn wave breaking and wave dissipation has the following advantages:

[0046] 1. For special environments such as islands, the present invention is simpler and more feasible to construct than the pile group structure, with low construction cost, which is conducive to promoting the industrialization process;

[0047] 2. Arrange them irregularly, and the group effect of the horns will be more obvious;

[0048] 3. For the outer bank protection structure with special requirements, it can be supplemented with the pile group structure to improve the protection efficiency;

[0049] 4. The starfish's five-pointed star structure is more stable.

[0050] The above descriptions are only preferred embodiments of the present invention, not all embodiments. Anyone should be aware that any structural changes made under the inspiration of the present invention, and any technical solutions that are the same or similar to the present invention, belong to the protection scope of the present invention.
