Description

Technical Field

[0001] This utility model relates to the field of water-retaining channel technology, and more specifically to a novel roadbed water-retaining channel. Background Technology

[0002] With the rapid advancement of transportation infrastructure construction, the stability of roadbed protection and drainage systems has become crucial for ensuring road safety. In mountainous areas, rainy sections, or sections with high embankments, surface runoff caused by rainfall can easily erode the roadbed, leading to soil erosion, structural deformation, and even landslides. Traditional water-retaining facilities such as concrete retaining walls, masonry, or gabion mesh have significant drawbacks: concrete structures are heavy, have long construction periods, and are prone to cracking due to foundation settlement; gabion mesh has poor integrity, weak impact resistance, and is prone to rust and loosening after long-term use. Furthermore, both types of structures are difficult to adapt to complex terrain and differential settlement, resulting in high maintenance costs and insufficient flexibility.

[0003] While modular and prefabricated protection technologies that have emerged in recent years (such as sheet pile support) are convenient to construct and have high strength, they still have technical bottlenecks: rigid interlocking between sheet pile units is prone to stress concentration under dynamic loads; the fixed form of the pile bottom is singular and difficult to adapt to soft soil or high water level foundations; the surface protection lacks ecological restoration design, resulting in landscape fragmentation and loss of ecological function; existing adjustable structures rely on on-site welding or complex mechanical adjustments, making it difficult to balance construction efficiency and safety. Utility Model Content

[0004] The purpose of this utility model is to provide a novel roadbed water-retaining channel in order to solve the above-mentioned technical problems.

[0005] The technical solution adopted by this utility model is as follows: A novel roadbed water-retaining channel includes: parallel steel plate units, each unit interlocking with each other to form a continuous support surface, the bottom of the steel plate unit is provided with spikes that are inserted into the roadbed soil layer; a support frame located inside the support surface, including support columns spaced apart along the length of the support surface and horizontal reinforcing crossbars connecting each column, the lower 1 / 3 of the support column is a precast concrete pile foundation, and the upper part is connected to an adjustable height steel column section through a flange; a detachable connecting assembly to anchor the reinforcing crossbars to the steel plate units; and a diamond-shaped woven steel wire rope net covering the outside of the support surface and connected to the steel plate units and the bottom foundation anchor point through an adjustable locking mechanism.

[0006] A continuous support surface is formed by interlocking steel plate units, combined with bottom spikes inserted into the soil layer, enabling the rapid construction of a stable support system. The support frame uses a combination of precast pile foundations at the bottom and adjustable steel columns at the top, ensuring both foundation bearing capacity and height adjustment functionality. A diamond-shaped steel wire rope net, in conjunction with a locking mechanism, forms a double protective layer. The overall structure combines the advantages of rapid assembly, stable support, and flexible protection, significantly improving the safety of roadbed splicing construction.

[0007] Preferably, the detachable connection assembly includes: a perforated connecting plate welded to the reinforcing crossbar; an annular clamp sleeved on the supporting column; and a bidirectional adjusting screw with the connecting plate and the clamp respectively hinged at both ends.

[0008] Preferably, the spiked portion comprises a front section and a rear section, the front section being made of spring steel and the rear section being made of alloy steel, and the two sections are connected by friction welding.

[0009] Preferably, a high-strength geogrid layer is embedded in the mesh of the wire rope net, and the geogrid layer forms a sandwich structure with the wire rope net through U-shaped buckles.

[0010] Preferably, the precast concrete pile foundation has a steel sleeve with internal threads embedded in it, and the pile top flange is connected to the steel sleeve through a prestressed anchor rod. The flange is provided with bolt holes arranged in a ring.

[0011] Preferably, the adjustable locking mechanism includes: an Ω-shaped steel buckle welded to the edge of the wire rope mesh; a grooved locking seat fixed to the steel plate unit; and a quick-release locking bolt passing through the Ω-shaped steel buckle and the locking seat.

[0012] Preferably, the surface of the steel plate unit is coated with a graphene-modified epoxy anti-corrosion coating.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. A continuous support surface is formed by the interlocking connection of steel plate units. Combined with the bottom spikes inserted into the soil layer and the three-dimensional support system of the inner support frame, a "plate-pile-anchor" collaborative force-bearing structure is formed, which improves the overall anti-overturning performance.

[0015] 2. The supporting columns utilize precast concrete pile foundations connected to adjustable steel column flanges, adapting to changes in foundation elevation and improving construction adjustment efficiency. Detachable connection components enable non-destructive assembly and disassembly, increasing reusability.

[0016] 3. The diamond-shaped steel wire rope mesh, combined with the built-in high-strength geogrid, forms a composite protective layer that absorbs impact energy and effectively prevents rockfall impacts and soil slippage. The Ω-shaped locking mechanism allows for a small range of displacement adjustment to adapt to minor foundation deformations.

[0017] 4. The spikes utilize a gradient material design, with nitriding at the front to increase hardness and nitriding at the rear to ensure structural toughness, thus reducing penetration resistance while improving durability. The graphene coating further enhances corrosion resistance and lifespan.

[0018] 5. Standardized prefabricated components reduce on-site welding work and increase installation speed. Quick-release connection mechanisms shorten the time for each assembly and disassembly, reducing construction costs.

[0019] 6. The adjustable spacing of the support frame, combined with the replaceable spike design, allows it to handle various soil layers. The protective netting system can be adjusted to create different slope protection angles by changing the spacing of the anchor points.

[0020] 7. Most of the materials used in the entire device are recyclable, and no grouting is required during construction, avoiding mud pollution. The ground disturbance depth is minimal after the temporary support is removed, which is beneficial for the subsequent construction of the permanent structure. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] In one embodiment of this utility model, such as Figure 1-7 As shown, this embodiment provides a novel roadbed water-retaining channel, comprising: parallel steel plate units 1, each unit interlocking with each other through a rolled edge 13 to form a continuous support surface, the bottom of the steel plate unit 1 having a spike 14 inserted into the roadbed soil layer; a support frame located inside the support surface, including support columns 5 spaced along the length of the support surface and horizontal reinforcing crossbars 3 connecting each column, the lower 1 / 3 of the support column 5 being a precast concrete pile foundation, the upper part being connected to an adjustable height steel column section via a flange; a detachable connecting assembly 4 for anchoring the reinforcing crossbars 3 to the steel plate units 1; and a diamond-shaped woven steel wire rope net 2 covering the outside of the support surface and connected to the steel plate units 1 and the bottom foundation anchor point through an adjustable locking mechanism. A continuous support surface is formed by the interlocking of steel plate units 1, combined with the insertion of the bottom spikes 14 into the soil layer, enabling the rapid construction of a stable support system. The support frame adopts a combination of precast pile foundations at the bottom and adjustable steel columns at the top, ensuring both foundation bearing capacity and height adjustment functionality. The diamond-shaped steel wire rope net 2, in conjunction with the locking mechanism, forms a double protective layer. The overall structure combines the triple advantages of rapid assembly, stable support, and flexible protection, significantly improving the safety of roadbed splicing construction.

[0033] In another embodiment of this utility model, the detachable connecting assembly 4 includes: a perforated connecting plate 41 welded to the reinforcing crossbar 3; an annular clamp 42 sleeved on the supporting column 5; and a bidirectional adjusting screw 43 with its two ends hinged to the connecting plate and the clamp respectively. The bidirectional adjusting screw 43, in conjunction with the perforated connecting plate 41 and the annular clamp 42, can simultaneously adjust the connection position between the reinforcing crossbar 3 and the steel plate in both horizontal and vertical directions, effectively compensating for construction errors; the hinged structure eliminates assembly stress, avoids deformation of the connecting parts, and ensures uniform stress distribution on the support surface.

[0034] In another embodiment of this utility model, the spike 14 comprises a front section and a rear section, the front section being made of spring steel and the rear section being made of alloy steel, the two sections being connected by friction welding. In a preferred embodiment of this utility model, the spring steel is selected as 60Si2Mn spring steel with surface nitriding treatment, and the alloy steel is selected as Q345B low alloy steel. The high-hardness spring steel in the front section enhances the penetration ability of the spike 14, and the surface nitriding treatment enhances wear resistance; the low alloy steel in the rear section maintains structural toughness and prevents pile deformation; the segmented material combination balances strength and economy, and the friction welding process ensures connection reliability and extends service life.

[0035] In another embodiment of this utility model, a high-strength geogrid layer is embedded within the mesh of the wire rope net 2. This geogrid layer forms a sandwich structure with the wire rope net 2 via U-shaped clips. The geogrid and the wire rope net 2 form a composite protective layer. The geogrid layer disperses the impact force of falling rocks, while the wire rope net 2 bears the main tensile force. The two work together to improve impact resistance. The U-shaped clips enable quick replacement of damaged parts, reducing maintenance costs, and are particularly suitable for road sections prone to falling rocks.

[0036] In another embodiment of this utility model, a steel sleeve with internal threads is pre-embedded in the precast concrete pile foundation. The pile top flange is connected to the steel sleeve through a prestressed anchor rod, and the flange has bolt holes arranged in a ring. The pre-embedded steel sleeve and the prestressed anchor rod form a rigid connection node, improving the pull-out resistance of the pile foundation; the ring arrangement of the flange bolt holes allows for 360-degree adjustment, which can meet the needs of roadbed splicing at different angles and significantly improves construction adaptability.

[0037] In another embodiment of this utility model, the adjustable locking mechanism includes: an Ω-shaped steel buckle welded to the edge of the wire rope mesh 2; a grooved locking seat 22 fixed to the steel plate unit 1; and a quick-release locking bolt 23 passing through the Ω-shaped steel buckle and the locking seat. The Ω-shaped steel buckle and the grooved locking seat 22 form a sliding connection, allowing the wire rope mesh 2 to adaptively adjust its position when the support surface deforms; the quick-release bolt enables single-person operation for assembly and disassembly, saving 70% of the working time compared to the traditional binding method, making it particularly suitable for rapid deployment in emergency rescue projects.

[0038] In another embodiment of this utility model, the surface of the steel plate unit 1 is coated with a graphene-modified epoxy anti-corrosion coating. The graphene-modified coating forms a dense protective film, improving salt spray resistance and corrosion resistance; the surface friction coefficient of the coating is ≤0.15, reducing soil adhesion, resulting in a high reusability of the steel plate and significantly reducing construction costs.

[0039] The construction process of this utility model is as follows: ① Measurement and layout to determine the axis of the support surface → ② Vibration installation of steel plate unit 1 → ③ Pouring of precast pile foundation and installation of support column 5 → ④ Erecting of reinforcing crossbar 3 and installation of connecting components → ⑤ Tensioning of steel wire rope net 2 and locking of Ω-shaped buckle → ⑥ Acceptance of overall structure.
