Description

Technical Field

[0001] The present invention relates to the technical field of ecological slope protection, and particularly relates to a grid-shaped ecological slope protection structure and an assembling method thereof. Background Art

[0002] Slope protection refers to the general term for various pavings and plantings done on the slope surface to prevent the slope from being scoured. Currently, there are two common slope protection structure types for seawalls: one is a rigid slope protection structure (such as concrete slope protection, mortar block stone slope protection, etc.). Except for a small number of expansion joints between plates and drainage holes, this type of slope protection structure is basically impermeable. Its advantages are a long effective protection time and good anti-scouring performance. Its limitations are that the structure type is closed, the water and soil environment inside the structure is basically completely isolated, which affects the living environment of attached marine organisms and microorganisms, and the slope surface of this type of slope protection structure is very hard, which affects the growth of aquatic plants and destroys the coastal ecological environment to varying degrees. The other is a flexible slope protection structure, which is divided into two categories: one is special-shaped blocks, also known as special-shaped wave-dissipating blocks, which are constructed from artificially precast concrete materials (such as king-sized twisted blocks, i-beam twisted blocks, four-corner hollow blocks, four-corner cones, fence plates, etc.). This type of structure helps to protect the ecological environment and conforms to the ecological concept, but the construction process of slope protection installation is complex, and the repair cost after partial damage under extreme conditions is relatively high; the other is constructed from natural or processed stone materials (such as randomly dumped riprap, dry-laid block stones, inserted strip stones, etc.). This type of slope protection also has a good ecological effect and low cost, but the overall stability and anti-scouring performance depend on the size, shape of the stone materials and the masonry method. There are large differences between the stone blocks, and the instability of individual weak blocks is very likely to lead to the instability of the entire slope protection structure. The overall stability of this type of slope protection structure is inferior to that of rigid slope protection structures and special-shaped wave-dissipating block slope protection structures.

[0003] In view of the above problems, we have designed a grid-shaped ecological slope protection structure and an assembling method thereof to solve the above problems. Summary of the Invention

A grid-shaped ecological slope protection structure and an assembling method thereof are proposed. The slope protection structure is convenient to install and easy to maintain and repair. As a slope protection structure for offshore projects, it has strong self-stability, good wave-dissipating effect, and large porosity, which helps to protect the ecological environment and conforms to the ecological concept.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0039] There are certain defects in existing seawall slope protection structures whether they adopt rigid slope protection structures or flexible slope protection structures. Rigid slope protection structures have poor water permeability, no ecological effect and poor aesthetics; flexible slope protection structures have certain requirements for construction technology, poor durability and potential overall instability hazards caused by damage to individual blocks. With the development of the times, extreme climates occur more frequently, and the overall social awareness of ecological protection has increased. There is an urgent need to propose an ecological slope protection structure that is suitable for seawalls, has good anti-scouring performance, strong stability and ecological effects. Therefore, in this embodiment, a grid-shaped ecological slope protection structure and its assembling method are proposed.

[0040] First, the grid-shaped ecological slope protection structure is introduced. This ecological slope protection structure is assembled by individual wave-dissipating main blocks 1 in the shape of a "grid".

[0041] The wave-dissipating main block 1 is a monolithic cast reinforced concrete structure. As Figure 1 and Figure 2 shown, the wave-dissipating main block 1 is composed of a first cross beam 2, a second cross beam 3, a third cross beam 4, a fourth cross beam 5, a first longitudinal beam 6 and a second longitudinal beam 7.

[0042] The first cross beam 2, the second cross beam 3, the third cross beam 4, and the fourth cross beam 5 are arranged in sequence and at equal intervals above the first longitudinal beam 6 and the second longitudinal beam 7. The two outer sides of the first longitudinal beam 6 and the second longitudinal beam 7 are flush with the two end sides of the first cross beam 2, the second cross beam 3, the third cross beam 4, and the fourth cross beam 5. The two end sides of the first longitudinal beam 6 and the second longitudinal beam 7 are flush with the sides of the first cross beam 2 and the fourth cross beam 5 respectively. The adjacent intervals between the first cross beam 2, the second cross beam 3, the third cross beam 4, and the fourth cross beam 5 are the same as the adjacent intervals between the first longitudinal beam 6 and the second longitudinal beam 7.

[0043] There is a first groove 8 between the first cross beam 2 and the second cross beam 3, a second groove 9 between the second cross beam 3 and the third cross beam 4, a third groove 10 between the third cross beam 4 and the fourth cross beam 5, and a fourth groove 11 between the first longitudinal beam 6 and the second longitudinal beam 7. The widths of the first groove 8, the second groove 9, the third groove 10 and the fourth groove 11 are the same. The length and height of the first cross beam 2, the second cross beam 3, the third cross beam 4 and the fourth cross beam 5 are the same. The length, width and height of the first longitudinal beam 6 and the second longitudinal beam 7 are the same.

[0044] The first cross beam 2 and the fourth cross beam 5 have the same width, the second cross beam 3 and the third cross beam 4 have the same width, and the width of the second cross beam 3 and the third cross beam 4 is twice the width of the first cross beam 2 and the fourth cross beam 5 .

[0045] In order to better implement the technical solution, when processing the main wave-breaking block 1, the size specifications can be used to manufacture the casting mold according to the following data. The length of the main wave-breaking block 1 is 2.4 meters, the width is 1 meter, and the height is 0.5 meters. Among them, the length of the first crossbeam 2, the second crossbeam 3, the third crossbeam 4 and the fourth crossbeam 5 is 1 meter, and the height is 0.3 meters; the width of the first crossbeam 2 and the fourth crossbeam 5 is 0.2 meters, and the width of the second crossbeam 3 and the third crossbeam 4 is 0.4 meters. The length of the first longitudinal beam 6 and the second longitudinal beam 7 is 2.4 meters, the width is 0.3 meters, and the height is 0.2 meters

[0046] After the mold is made, steel bars are placed in the mold and concrete is poured to achieve one-time casting of the main wave-breaking block 1. After the curing is completed, the main wave-breaking block 1 is demoulded and stored and loaded for transportation by stacking with beams embedded in grooves, which reduces the floor space of the main wave-breaking block 1 and improves transportation efficiency and convenience. The main wave-breaking block 1 has a very simple structure, which is convenient for mold making, transportation, installation and other links, and reduces production and transportation costs.

[0047] According to the structural characteristics of the main wave-dissipating block 1, this embodiment further proposes a method for assembling a U-shaped ecological slope protection structure, such as Figure 3 As shown, the assembly method includes:

[0048] S1. Excavate a slope foundation trench on the target seawall slope. It should be noted that the surface of the slope foundation trench is flat and excavated to a uniform inclination angle in accordance with the requirements of the construction drawings to ensure that the upper end surface of the lower wave-breaking main block 1 remains flat after being laid, laying the foundation for the mortise and tenon assembly of the upper wave-breaking main block 1 and the overall stability of the ecological slope protection structure.

[0049] S2, the main wave-breaking blocks 1 are evenly arranged on the slope foundation trench. Specifically,

[0050] The wave-dissipating main blocks 1 are evenly arranged on the slope foundation trench as follows:

[0051] S21, the ends of the first cross beam 2, the second cross beam 3, the third cross beam 4 and the fourth cross beam 5 of two adjacent wave-breaking main blocks 1 on the left and right sides are aligned with each other.

[0052] S22, the side surfaces of the first cross beam 2 of the front end wave-breaking main block 1 and the fourth cross beam 5 of the rear end wave-breaking main block 1 abut against each other.

[0053] S23, the second longitudinal beam 7 of the left wave-breaking main block 1 is kept flush with the end of the first longitudinal beam 6 of the right wave-breaking main block 1, and the side surfaces of the first longitudinal beam 6 and the second longitudinal beam 7 are butted against each other;

[0054] S24, the first longitudinal beam 6 of the front end wave-breaking main block 1 butts against the end of the first longitudinal beam 6 of the rear end wave-breaking main block 1, and the end of the second longitudinal beam 7 of the front end wave-breaking main block 1 butts against the end of the second longitudinal beam 7 of the rear end wave-breaking main block 1.

[0055] S3, the upper wave-breaking main block 1 is flipped downward and inverted onto the wave-breaking main block 1 that has been laid in S2, the crossbeams and grooves between the upper and lower wave-breaking main blocks 1 are mortise-jointed with each other, and one upper wave-breaking main block 1 is mortise-jointed and fixed to the middle parts of the four lower wave-breaking main blocks 1.

[0056] Reference Figure 4 The cross beams and grooves between the upper and lower wave-breaking main blocks 1 are mortised in the following manner:

[0057] S31, the first cross beam 2, the second cross beam 3, the third cross beam 4, the fourth cross beam 5 and the first longitudinal beam 6 and the second longitudinal beam 7 of the upper wave-breaking main block 1 are arranged toward the evenly laid wave-breaking main block 1 of the lower layer.

[0058] S32, inserting the first cross beam 2 of the upper wave-breaking main block 1 into the second grooves 9 of two adjacent wave-breaking main blocks 1 on the left and right sides of the front end of the lower layer, and inserting the second cross beam 3 into the third groove 10.

[0059] S33, insert the third cross beam 4 of the upper wave-breaking main block 1 into the first groove 8 of the two adjacent wave-breaking main blocks 1 on the left and right sides of the lower layer, and insert the fourth cross beam 5 into the second groove 9 of the two adjacent wave-breaking main blocks 1 on the left and right sides of the lower layer.

[0060] S34, after the upper and lower wave-breaking main blocks 1 are mortise-jointed with each other, the direction of the central axis of the upper wave-breaking main block 1 and the direction of the splicing line between the left and right wave-breaking main blocks 1 of the lower layer are located on the same vertical plane, and one wave-breaking main block 1 of the upper layer is mortise-jointed and fixed in the middle of the four wave-breaking main blocks 1 of the lower layer.

[0061] There are two placement methods for the slope protection structure. Method 1 is that the first longitudinal beam 6 and the second longitudinal beam 7 of the wave-breaking main block 1 are perpendicular to the direction of the wave and water flow, and method 2 is that the cross beam of the wave-breaking main block 1 is perpendicular to the direction of the wave and water flow. Placement method 2 increases the contact area between the wave, water flow and the wave-breaking block, thereby accelerating the energy dissipation of the wave, and its wave-breaking effect is better than that of placement method 1.

[0062] In the preferred embodiment 2, when the discharge direction of the first beam 2, the second beam 3, the third beam 4 and the fourth beam 5 of the upper and lower wave-breaking main blocks 1 is perpendicular to the direction of the wave flow, the stable thickness calculation formula of the ecological slope protection structure formed by discharge in this way is as follows:

[0063]

[0064] In the formula, is the relative stable thickness of the ecological slope protection structure, where D is the stable thickness of the ecological slope protection structure, which is the accumulated thickness of the stacked layers of the ecological slope protection structure, H is the design wave height; L is the wavelength, α is the angle between the slope and the horizontal plane, ρ b is the density of the ecological slope protection structure, ρ is the density of water, R is the fitting coefficient, and the relative stable thickness of the ecological slope protection structure is Follow The change of is obtained by fitting, and R is taken as 0.110 based on the experimental results.

[0065] According to the above calculation formula, the placement thickness of the ecological slope protection structure can be determined, providing a scientific calculation basis for the assembly of the ecological slope protection structure.

[0066] S4, according to S3 splicing combination method ( Figure 5 As shown), the assembled wave-breaking main blocks 1 are arrayed on the slope base trench to form an overall ecological slope protection structure.

[0067] In summary, the splicing method of the wave-breaking main blocks 1 in this embodiment is that the first layer of wave-breaking main blocks 1 are arranged uniformly in an array, the second layer of wave-breaking main blocks 1 are arranged at intervals, the upper and lower layers of wave-breaking main blocks 1 are mortise-jointed with each other, and one upper layer of wave-breaking main block 1 is mortise-jointed to fix the four lower layer of wave-breaking main blocks 1. This assembly method makes the ecological slope protection structure itself more stable, increases the overall stability and scouring resistance of the ecological slope protection structure, and can withstand direct scouring of waves for a long time. The physical model test verifies that the self-stability of the eye-shaped ecological slope protection structure when interacting with waves is strong.

[0068] If the second layer of wave-breaking main blocks 1 is not covered, under the long-term and severe impact of waves and currents, the first layer of wave-breaking main blocks 1 arranged in an array and not fixed by external force are very likely to shift, affecting the overall wave-breaking effect of the ecological slope protection; if the second layer of wave-breaking main blocks 1 are also arranged in an array, although the overall stability of the ecological slope protection structure is enhanced, the number of wave-breaking main blocks 1 used is also greatly increased, and it also has an adverse negative impact on the ecological environment. Therefore, the splicing method proposed in this implementation saves the mold making cost while ensuring the overall stability of the ecological slope protection structure. The ecological slope protection structure has concave and convex spaces and a large porosity, which can effectively alleviate the flow velocity of water, enhance the wave-breaking effect, and provide a place for the growth of aquatic plants and the habitat, foraging, reproduction, and development of aquatic animals. It has the function of protecting the ecological environment of the offshore area and takes into account the protection of the marine ecological environment.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
