Description

Technical Field

[0001] This invention relates to a modular ecological drainage ditch structure suitable for mountain slopes, specifically belonging to the field of geological disaster prevention and civil engineering technology. Background Technology

[0002] In landslide control in the mountainous areas of Guizhou, surface drainage is a crucial and primary measure, aiming to quickly divert surface water, reduce rainwater infiltration, and thus lower the pore water pressure within the landslide body. Traditional surface drainage ditches typically employ cast-in-place concrete or masonry structures, which have the following significant drawbacks: 1. Construction difficulties: The mountainous terrain of Guizhou is steep and transportation is inconvenient, making on-site pouring or masonry construction difficult, time-consuming and costly.

[0003] 2. Rigid failure: Traditional drainage ditches are rigid structures, which are prone to cracking and failure when uneven settlement or slight deformation of the foundation occurs (which is common in landslide-prone areas).

[0004] 3. Ecological barriers: Concrete or masonry structures completely sever the vegetation on the slope, destroying the original ecological continuity and hindering soil and water conservation and ecological restoration.

[0005] 4. Difficult to maintain: Once a blockage or damage occurs, repair and dredging are quite difficult.

[0006] Therefore, there is an urgent need for a new type of drainage ditch structure that is easy to transport and construct, can adapt to certain deformations, and also has ecological functions. Summary of the Invention

[0007] The purpose of this invention is to provide a modular ecological drainage ditch structure suitable for mountain slopes, so as to provide a prefabricated, modular drainage ditch structure with certain flexibility and ecological benefits.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: The invention includes a ditch assembled from multiple unit modules along a drainage path; the unit module is a prefabricated U-shaped trough structure, with matching protruding connecting parts and recessed connecting parts at both ends, so that adjacent unit modules can be detachably fastened together.

[0009] Furthermore, modular prefabricated components make the overall structure lightweight, easy to transport to mountainous sites by manpower, and quick to assemble, significantly shortening the construction period and reducing construction costs and difficulties. The mortise and tenon connections between modules allow for minor rotation and displacement, making the entire drainage ditch system a semi-rigid whole, which can better adapt to minor deformations of the slope and is not prone to cracking, with a reliability far exceeding that of traditional rigid ditches. If a section of a module is damaged, it can be easily removed and replaced, resulting in extremely low maintenance costs.

[0010] Multiple ecological holes are provided on the side wall of the unit module.

[0011] Furthermore, the ecological perforation design promotes vegetation restoration, allowing the drainage ditch to blend seamlessly with the surrounding natural environment and avoiding the harshness and ecological barrier effect of traditional concrete structures. Plant roots also help to stabilize the soil around the ditch, preventing soil erosion along the ditch walls.

[0012] The bottom outer side of the unit module is provided with protruding anchoring teeth.

[0013] Furthermore, the anchoring teeth can increase the friction between the module and the foundation, preventing the drainage ditch from sliding along the slope after installation. This is especially suitable for steep terrain and ensures the long-term stability of the drainage system.

[0014] The ecological openings are concentrated on one side wall of the unit module.

[0015] Furthermore, by focusing ecological functions on the side where they are needed, vegetation restoration and soil and water conservation become more targeted, while ensuring the integrity and strength of the other side of the drainage ditch structure.

[0016] The ecological holes are circular.

[0017] Furthermore, circular holes are easier to manufacture and are less prone to stress concentration points when subjected to force, which helps to improve the overall strength and durability of the module.

[0018] The anchoring teeth have an inverted conical structure.

[0019] Furthermore, the inverted cone structure provides stronger interlocking force and pull-out resistance in the soil, further enhancing the anchoring effect of the drainage ditch on the slope.

[0020] The raised connecting part is the male tenon, and the recessed connecting part is the female tenon groove.

[0021] Furthermore, the mortise and tenon joint method enables rapid assembly and accurate positioning, providing a good foundation for any subsequent sealing measures that may be added.

[0022] A sealing ring groove is provided at the joint between the male tenon and the female tenon.

[0023] Furthermore, the sealing ring groove is used to place the sealing ring, which can effectively prevent water from leaking from the joints between modules, protect the slope structure, and improve the reliability and efficiency of the drainage system.

[0024] The unit modules are prefabricated from fiber-reinforced composite materials or engineering plastics.

[0025] Furthermore, the material selection results in a structure that is lightweight, high-strength, corrosion-resistant, and weather-resistant, making it ideal for mountain transportation and harsh environments, thus ensuring the product's lifespan.

[0026] The beneficial effects of this invention are: 1. The modular design brings excellent ease of construction and maintenance; the whole structure is assembled from prefabricated unit modules through protruding and recessed connecting parts at both ends; this allows for the rapid laying and dismantling of drainage ditches in steep mountainous areas without the need for large machinery, greatly reducing construction difficulty, time and cost; at the same time, if a part is damaged, a single module can be precisely replaced, resulting in extremely low maintenance costs. 2. The inverted conical anchoring teeth on the outer bottom of the unit module can be effectively embedded into the foundation, increasing anti-slip friction and preventing the ditch from sliding along the slope. The mortise and tenon connection itself and the material properties of fiber-reinforced composite materials / engineering plastics make the overall structure a semi-rigid body. It can adapt to the uneven settlement of the slope and other minor deformations through small rotations and displacements, avoiding the drawbacks of traditional rigid structures that are prone to cracking, and thus has stronger durability.

[0027] 3. By creating circular ecological holes on the side walls of the unit modules (especially the side facing the mountain), a channel is provided for the growth of plant roots, so that the drainage ditch can be quickly covered by vegetation while performing its drainage function, restoring the ecological continuity of the slope, which not only stabilizes the soil and protects the slope, but also beautifies the landscape; the sealing ring groove at the joint of the male tenon and the female tenon further ensures the sealing of the connection between the modules and prevents leakage.

[0030] The following will be combined with the appendix Figure 1-4 The technical solutions in the embodiments are described clearly and completely.

[0031] Specific implementation method one: as follows Figures 1-2As shown, the modular ecological drainage ditch structure of the present invention is primarily composed of multiple prefabricated unit modules 1 assembled together. The unit module 1 is a U-shaped trough structure, preferably made of fiber-reinforced composite material or engineering plastic and prefabricated in a factory. Each end of the unit module 1 is provided with a matching protruding connecting part 2 and a recessed connecting part 3, allowing adjacent unit modules 1 to be detachably connected by a mortise and tenon structure. A sealing ring groove is provided at the joint of the male tenon and the female tenon groove to place a sealing ring to enhance the sealing of the connection and prevent leakage.

[0032] Specific implementation method two: such as Figures 2-4 As shown, based on the first specific implementation method, multiple ecological holes 4 are provided on the side wall of the unit module 1; the ecological holes 4 are preferably circular holes, and can be concentrated on a single side wall of the unit module 1 (i.e. the side expected to be closer to the hillside); the bottom outer side of the unit module 1 is provided with protruding anchoring teeth 5, which are preferably inverted conical structures to enhance their anchoring force with the foundation and prevent the ditch from sliding.

[0033] Workflow: Based on the design dimensions, fiber-reinforced composite materials (such as resin + glass fiber) or engineering plastics are used to mass-produce complete unit modules 1 in the factory using molds; each unit module 1 is prefabricated with male tenons 2, female tenons 3, ecological holes 4, and anchoring teeth 5, etc. On landslide slopes requiring surface drainage, shallow trenches are excavated along the designed route and the foundation is leveled. Prefabricated unit modules 1 are transported to the site. Construction workers assemble the modules from bottom to top along the trenches, quickly connecting them like building blocks by inserting the male tenon 2 of the next unit module 1 into the female tenon 3 of the previous unit module 1, forming a continuous drainage ditch. After all unit modules 1 are assembled, backfilling is carried out on the side of the ditch closest to the mountain. Grass seeds, shrub seeds, and fertilizer can be pre-mixed into the backfill soil so that plants can grow through the ecological holes 4 in the future. Routine maintenance requires regular inspection of the drainage ditch, clearing fallen leaves, debris, etc., to ensure unobstructed drainage. If individual unit modules 1 are damaged due to extreme circumstances (such as rockfall impact), they can be precisely located, and then the damaged unit module 1 can be removed and replaced with a new unit module 1, making maintenance very simple.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments without departing from the scope of the present invention, based on the technical essence of the present invention and within the spirit and principles of the present invention, shall still fall within the protection scope of the present invention.
