UTILITY MODEL CONTENTS

[0003] In view of the prior art, the utility model provides a kind of city wetland ecological slope protection structure, to solve the problem of low slope protection strength of the slope protection board on the slope surface of traditional city wetland ecological slope protection.

[0004] To achieve the above purpose, the utility model provides a kind of city wetland ecological slope protection structure, including a plurality of for laying on the ecological slope surface of outside slope protection group, each group of the slope protection group is by two slope protection boards, the slope protection board outer wall is uniformly distributed with a plurality of baffle along its height direction, the slope protection board is penetrated with the groove corresponding to each baffle position, the baffle inner wall and groove opening are formed with the planting gap for filling outside nutrient soil and planting outside plant between, the slope protection board inner wall is provided with the reinforcing member for being stably connected with outside slope surface and conducting the external load received by slope protection board, two slope protection boards in each group of the slope protection group are all provided with connecting piece for connecting two slope protection boards and conducting part load to another slope protection board when single slope protection board is loaded by external load.

[0005] The technical scheme has the beneficial effects that: the two slope protection plates are spliced together through the connecting pieces, ensuring firm connection, and the installation positions of the connecting pieces are accurate, so that the connecting pieces can smoothly conduct the load, the assembled slope protection groups are carried to the wetland slope surface one by one, and the slope protection plates are laid from the bottom of the slope according to the designed laying scheme. During the laying process, the positions of the slope protection plates are adjusted, the reinforcing pieces are fully in contact with the slope surface, the prepared nutrient soil is poured into the planting gaps of each slope protection plate, and the plant seedlings suitable for the growth of the wetland environment are planted in the planting gaps, so that the preliminary slope protection effect is achieved. In the above technology, the reinforcing pieces are stably connected with the slope surface to disperse the load borne by the slope protection plates, and the connecting pieces are used to realize the load conduction between the slope protection plates, so that a stable stress system is formed, the problem of low slope protection strength of the traditional slope protection plate is effectively solved, stronger water flow scouring and soil subsidence forces can be resisted, the planting gaps formed by the baffles and the containers are used to successfully introduce the plant planting link, the slope protection is strengthened, the habitat of the wetland organisms is provided, the material circulation and energy flow of the ecological system are promoted, the functional requirements of ecological protection and restoration are considered, that is, during the growth of the plants, the plant roots penetrate into the deep soil through the pores, and the roots are intertwined, like a natural anchoring system, so that the soil cohesion is further enhanced, the risk of water and soil loss is significantly reduced, and compared with the traditional hard slope protection, the soil loss amount can be reduced by 70%-90%.

[0006] The utility model further sets up: the reinforcing piece includes a plurality of reinforcing plate for inserting outside ecological slope, a plurality of reinforcing plate evenly distributes on the slope protection plate inner wall along the height direction, the reinforcing plate evenly distributes along its length direction and forms a plurality of hump part, the hump direction of adjacent hump part is opposite setting, the reinforcing plate is set in wave shape.

[0007] The technical scheme has the beneficial effects that: the reinforcing member is composed of reinforcing plates which are uniformly distributed along the height direction of the slope protection plate, and the reinforcing plates are inserted into the external ecological slope surface to form a stable connection with the slope surface. When subjected to external loads such as water flow scouring, rain impact, soil settlement and the like, the reinforcing plates, like "anchor piles" deeply rooted in the slope surface, uniformly disperse and transmit the force borne by the slope protection plate to the soil body of the slope surface, greatly reducing the local stress borne by the slope protection plate, effectively avoiding structural damage caused by stress concentration, and solving the problem of low slope protection strength of the traditional slope protection plate; meanwhile, the reinforcing plates are arranged in a wave shape and uniformly have protruding portions with opposite protruding directions along the length direction thereof. Compared with the traditional straight plate-shaped reinforcing member, the unique wave-shaped design greatly increases the contact area with the soil of the slope surface. More contact points and frictional forces make the connection between the reinforcing plate and the soil body of the slope surface more stable and tight, and the reinforcing plate can more efficiently disperse the load to the surrounding soil body when subjected to stress, further strengthening the ability of the slope protection plate to resist external damage and enabling the slope protection plate to withstand more powerful water flow scouring and complex soil environment changes; the wave-shaped reinforcing plate has better structural stability, and the opposite arrangement of the adjacent protruding portions makes the stress distribution more balanced and less likely to bend and deform during long-term stress. Compared with the ordinary straight plate structure, this design prolongs the service life of the reinforcing member, reduces the cost of frequent maintenance and replacement due to damage of the reinforcing member, and ensures long-term stable operation of the entire ecological slope protection structure, which is of great significance to the continuous protection and ecological maintenance of urban wetlands.

[0008] The utility model further sets up: two slope protection plates in each group of slope protection group are first fixed plate and second fixed plate respectively, first fender is provided on the right side wall of first fixed plate, second fender for stacking with first fender is provided on the left side wall of second fixed plate, coaxial through -hole is all provided on first fender and second fender, and the connecting piece includes connecting pin for being arranged in through -hole and being partially placed in external slope surface.

[0009] The technical scheme has the beneficial effects that: the stacking structure of the first fender and the second fender increases the contact area between the two slope protection plates compared with simple splicing, and makes the connection between the two slope protection plates more tight. When one of the slope protection plates is subjected to external loads, the larger contact area can more evenly disperse the stress and reduce the situation of excessive local stress, thereby improving the structural stability of the entire slope protection group. The coaxial through -hole provided on the first fender and the second fender and the connecting pin matched therewith provide reliable rigid connection for the two slope protection plates. The connecting pin is not only arranged in the through -hole, but also partially placed in the external slope surface, thereby firmly "nailing" the two slope protection plates together and further stabilizing the connection by means of the soil of the slope surface. When subjected to complex external forces such as water flow impact and soil settlement, the two slope protection plates can still maintain a cooperative stress state, thereby significantly strengthening the anti -damage ability of the entire slope protection.

[0010] The present invention further comprises: a first corrugated groove is provided on the right side wall of the first fixed plate and the left side wall of the second fixed plate; a second corrugated groove is provided on the side wall of the first stop for engaging with the first corrugated groove of the second fixed plate; and a third corrugated groove is provided on the side wall of the second stop for engaging with the first corrugated groove of the first stop.

[0011] The advantages of adopting the above technical solution are: the first corrugated grooves on the sidewalls of the first and second fixed plates, and the second and third corrugated grooves corresponding to the first and second retaining edges, respectively, greatly increase the tightness of the connection between the slope protection panels through their interlocking mechanism. This interlocking design of the corrugated grooves, compared to ordinary flat bonding, forms a tenon-and-mortise interlocking structure, capable of withstanding greater lateral and longitudinal tensile forces. It effectively resists the separation and misalignment of the slope protection panels that may occur under the influence of external forces such as water flow impact and soil settlement, providing multiple guarantees for the stability of the slope protection group. When encountering high-intensity water erosion, the lateral force exerted on the slope protection panels by the water flow is enormous. These nested corrugated grooves, like tightly meshed gears, evenly distribute the external forces from all directions to the entire connection area, preventing stress concentration at a single point and maintaining the coordination between the two slope protection panels. Under the same stress state, the entire slope protection structure is stabilized, which significantly improves the impact resistance of the slope protection system. The interlocking of the corrugated grooves improves the load transmission mechanism, making the load transfer between slope protection panels smoother and more uniform. When a single slope protection panel is subjected to external load, the interlocking corrugated grooves can accurately guide the stress to diffuse along the groove structure to the adjacent slope protection panels. Together with the connection between the reinforcement and the slope surface, it further optimizes the load transmission path from the slope protection panel to the slope surface of the entire slope protection system, improves the slope protection capacity to bear various complex loads, and comprehensively solves the problem of insufficient slope protection strength of traditional slope protection panels.

[0012] The present invention further includes the following feature: the slope protection board is made of high-strength precast concrete.

[0013] The advantages of adopting the above technical solution are: the slope protection panels are made of high-strength precast concrete, which gives them excellent compressive and flexural strength, enabling them to withstand complex external forces in wetland environments, such as continuous water erosion and lateral pressure from the slope soil. Compared to slope protection panels made of ordinary concrete or other materials, high-strength concrete slope protection panels are less prone to structural damage such as cracks and breakage when facing the impact of turbulent water flow during the rainy season, thus building a solid defense for the entire ecological slope protection system and further improving the overall slope protection strength; at the same time, the precast nature of the slope protection panels allows manufacturers to produce slope protection panels of specific sizes according to the slope length, height, and angle requirements, thereby meeting the needs of different slopes and facilitating the installation of the slope protection panels.

[0014] The present invention further includes the following feature: an air-entraining agent is added to the slope protection board during prefabrication to form uniformly patched micro-gaps inside the board with a porosity of 15%-25%.

[0015] The advantages of adopting the above technical solution are as follows: In this technology, an air-entraining agent is added during the prefabrication of the slope protection slab, resulting in uniformly distributed micro-pores within the slab, with a porosity controlled at 15%-25%. These micro-pores act like "buffer airbags," absorbing and dispersing energy when the slope protection slab is impacted by external forces. This effectively reduces stress concentration, decreases the risk of slab breakage due to excessive instantaneous impact, and enhances the toughness and durability of the slope protection slab against sudden external forces. Simultaneously, the porous structure provides excellent air permeability, allowing air to smoothly pass through the micro-pores and reach the plant roots. This is significant for wetland plants planted in the gaps between the slope protection slabs. Sufficient oxygen supply ensures root respiration, promotes healthy root growth, and allows the roots to better anchor themselves in the slope soil, stabilizing the slope protection system. Furthermore, the porosity also helps with water storage and regulation. During periods of abundant rainfall, the voids can absorb and temporarily store some rainwater, preventing water accumulation on the slope and avoiding the risk of landslides caused by excessive soil moisture. During dry periods, the stored water can be slowly released, maintaining a moderately humid environment necessary for plant growth and enhancing the overall adaptability of the ecological slope protection structure to the variable climate conditions of wetlands. Simultaneously, the internal voids reduce the weight of the slope protection panels, which can be 15%-30% lighter than solid slope protection panels of the same volume. In the construction phase, the lighter slope protection panels are easier to handle, hoist, and lay, reducing reliance on large machinery and lowering construction difficulty and costs. During transportation, the reduced weight also increases the single-trip transport capacity, improving transportation efficiency, accelerating the overall project progress, and indirectly shortening the construction cycle of urban wetland ecological slope protection. The prefabrication process and method involving the addition of air-entraining agents described above are existing technologies, therefore their structure and function will not be elaborated further.
