Abstract
Description
Technical Field
[0001] This application relates to the field of drainage ditch technology, and in particular to a slope toe anti-slip drainage ditch structure. Background Technology
[0002] A drainage ditch is a linear drainage facility used to guide and discharge surface water or groundwater. It is usually set up in areas such as roads, squares, around buildings, and farmland. It generally consists of a ditch body, a cover (some have one), an inlet, and an outlet. The ditch body is mostly rectangular, trapezoidal, or circular in shape and is constructed of materials such as concrete and brick. It can effectively collect rainwater, snowmelt, and other accumulated water on the ground and guide it to designated drainage points, such as rivers, lakes, and sewage treatment plants. This avoids the adverse effects of water accumulation on the surrounding environment, building foundations, and traffic, and plays an important role in protecting the site, preventing soil erosion, and ensuring the normal operation of infrastructure.
[0003] Generally, the elevation of the top surface of the drainage ditch at the toe of the fill slope only needs to be set to the same height as the natural ground level. Figure 2 As shown, the existing anti-slip drainage ditch structure includes a drainage ditch bottom plate, natural ground and slope. Under this working condition, the active earth pressure formed by the soil on the slope toe side (left side) pushes the drainage ditch to slide and rotate to the right. Since the drainage ditch is embedded in the soil, the soil on the right side can provide enough passive earth pressure to resist the drainage ditch to slide to the right and rotate clockwise.
[0004] However, in recent mountain engineering projects, it is common to encounter situations where drainage ditches need to be installed at the toe of fill slopes. But in low-lying areas, these drainage ditches need to be raised above the natural ground level, such as... Figure 3 As shown, under this working condition, the active earth pressure formed by the soil on the slope toe (left side) pushes the drainage ditch to slide to the right and rotate clockwise. Since the drainage ditch is not embedded in the soil, there is no soil on the right side to provide passive earth pressure to the drainage ditch, which causes the drainage ditch to slide and rotate to the right under the action of the active earth pressure on the left side. This leads to the displacement and overturning of the drainage ditch, which can easily cause the entire drainage ditch system to be paralyzed. Based on this, a slope toe anti-slip drainage ditch structure is proposed to optimize it. Utility Model Content
[0005] The main purpose of this application is to provide a slope toe anti-slip drainage ditch structure, which aims to solve the aforementioned technical problems, so as to better withstand external forces, improve the anti-overturning ability, and avoid the displacement and overturning of the drainage ditch.
[0006] To solve the aforementioned technical problems, this application provides a slope toe anti-slip drainage ditch structure, including a drainage ditch bottom plate, a first drainage ditch sidewall and a second drainage ditch sidewall installed on the top of the drainage ditch bottom plate, the first drainage ditch sidewall being disposed on the side of the drainage ditch bottom plate close to the slope, and the second drainage ditch sidewall being disposed on the side of the drainage ditch bottom plate close to the natural ground.
[0007] An anti-overturning toe plate is fixedly connected to one end of the bottom plate of the drainage ditch near the side wall of the first drainage ditch. The anti-overturning toe plate extends outward relative to the bottom plate of the drainage ditch, and the extension direction of the anti-overturning toe plate is parallel to the extension direction of the bottom plate of the drainage ditch.
[0008] The bottom of the drainage ditch base plate is provided with anti-slip tenons.
[0009] Optionally, in some embodiments of this utility model, the drainage ditch bottom plate, the first drainage ditch sidewall, the second drainage ditch sidewall, the anti-overturning toe plate, and the anti-slip tenon are all provided with a steel reinforcement frame.
[0010] Optionally, in some embodiments of this utility model, the steel reinforcement skeletons in the drainage ditch bottom plate, the first drainage ditch sidewall, the second drainage ditch sidewall, the anti-overturning toe plate, and the anti-slip tenon are welded together.
[0011] Optionally, in some embodiments of this utility model, the diameter of the reinforcing bars in the above-described reinforcing bar cage ranges from 12 to 20 mm.
[0012] Optionally, in some embodiments of this utility model, the anti-slip tenon described above is provided with a first fixing member.
[0013] Optionally, in some embodiments of this utility model, the anti-overturning toe plate described above is provided with a second fixing member.
[0014] Optionally, in some embodiments of the present invention, an L-shaped anchor plate is provided at one end of the drainage ditch bottom plate near the side wall of the second drainage ditch, and the protrusion of the L-shaped anchor plate faces the side away from the drainage ditch bottom plate.
[0015] Optionally, in some embodiments of this utility model, the cross-section of the anti-slip tenon described above is an inverted trapezoid.
[0016] Optionally, in some embodiments of this utility model, the drainage ditch bottom plate, the first drainage ditch sidewall, and the second drainage ditch sidewall are arranged to form a U-shaped trough, and the inner surface of the U-shaped trough is coated with a waterproof coating.
[0017] Optionally, in some embodiments of this utility model, the thickness of the waterproof coating is 2mm to 4mm.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] Anti-slip protrusions are installed at the bottom of the drainage ditch base plate. When the active earth pressure generated by the slope soil on the left side of the first drainage ditch sidewall pushes the anti-slip drainage ditch structure at the slope toe to slide to the right, the anti-slip protrusions embedded in the soil will be resisted by the soil, providing sufficient sliding resistance for the anti-slip drainage ditch structure at the slope toe and preventing it from sliding to the right.
[0020] An anti-overturning toe plate is installed on the side of the bottom plate of the drainage ditch close to the side wall of the first drainage ditch. When the active earth pressure generated by the soil on the left slope causes the drainage ditch structure to tend to rotate clockwise, the weight of the fill slope soil pressing on the anti-overturning toe plate will generate a resistance force opposite to the rotation trend, preventing the slope toe anti-slip drainage ditch structure from rotating clockwise.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.
[0031] In order to achieve the above objectives,
[0032] Reference Figure 1 The embodiments of this application provide a slope 7 slope toe anti-slip drainage ditch structure, including a drainage ditch bottom plate 1, a first drainage ditch sidewall 2 and a second drainage ditch sidewall 3 installed on the top of the drainage ditch bottom plate 1, the first drainage ditch sidewall 2 being disposed on the side of the drainage ditch bottom plate 1 near the slope 7, and the second drainage ditch sidewall 3 being disposed on the side of the drainage ditch bottom plate 1 near the natural ground 8; by the first drainage ditch sidewall 2 and the second drainage ditch sidewall 3 being disposed at intervals at both ends of the top of the drainage ditch bottom plate 1, they form a U-shaped trough, forming a drainage ditch at the slope toe of the slope 7.
[0033] An anti-overturning toe plate 5 is fixedly connected to one end of the drainage ditch bottom plate 1 near the side wall 2 of the first drainage ditch. The anti-overturning toe plate 5 extends outward relative to the drainage ditch bottom plate 1, and the extension direction of the anti-overturning toe plate 5 is parallel to the extension direction of the drainage ditch bottom plate 1. When the active earth pressure generated by the soil of the left slope 7 causes the drainage ditch structure to have a clockwise rotation tendency, the weight of the fill slope 7 soil pressing on the anti-overturning toe plate 5 will generate a resistance force opposite to the rotation tendency, preventing the drainage ditch from rotating clockwise.
[0034] The bottom of the drainage ditch base plate 1 is provided with an anti-slip tenon 4. When the active earth pressure generated by the slope 7 on the left side of the first drainage ditch side wall 2 pushes the drainage ditch structure to slide to the right, the anti-slip tenon 4 embedded in the soil will be resisted by the soil, thereby providing sufficient sliding resistance to the drainage ditch structure.
[0035] Furthermore, as an optional implementation, the drainage ditch bottom plate 1, the first drainage ditch sidewall 2, the second drainage ditch sidewall 3, the anti-overturning toe plate 5, and the anti-slip tenon 4 are all provided with a steel reinforcement frame.
[0036] The drainage ditch bottom slab 1 is provided with a bottom slab steel reinforcement skeleton 101, the first drainage ditch sidewall 2 is provided with a first sidewall steel reinforcement skeleton 201, the second drainage ditch sidewall 3 is provided with a second sidewall steel reinforcement skeleton 301, and the anti-overturning toe slab 5 is provided with a toe slab steel reinforcement skeleton 501. They are all fixed with the tenon steel reinforcement skeleton 401. This steel reinforcement skeleton system enhances the integrity and strength of the drainage ditch structure, better withstands external forces, and improves the drainage ditch's ability to resist slippage and overturning.
[0037] Optionally, in this embodiment, the steel reinforcement cage, the first side wall steel reinforcement cage 201, the second side wall steel reinforcement cage, the toe plate steel reinforcement cage 501, and the tenon steel reinforcement cage 401 are all integrally welded.
[0038] Specifically, the diameter of the reinforcing bars in the steel reinforcement cage of this embodiment ranges from 12 to 20 mm.
[0039] Furthermore, the anti-overturning toe plate 5 and the drainage ditch bottom plate 1 are integrally formed. This integral forming structure ensures the connection strength between the anti-overturning toe plate 5 and the drainage ditch bottom plate 1, improving the stability of the entire drainage ditch structure.
[0040] Furthermore, the first drainage ditch sidewall 2 and the second drainage ditch sidewall 3 are connected to the drainage ditch bottom slab 1 by concrete pouring. This concrete pouring connection method ensures a tight bond between the drainage ditch sidewalls and the drainage ditch bottom slab 1, forming a unified structure and enhancing the overall integrity and stability of the drainage ditch. The first drainage ditch sidewall 2 and the second drainage ditch sidewall 3 are connected to the drainage ditch bottom slab 1 by concrete pouring. The concrete strength grade used is C25, and a vibrator is used during pouring to ensure thorough compaction and eliminate defects such as honeycomb or pitting.
[0041] The anti-overturning toe plate 5 extends to a length of 1 / 3 to 1 / 2 of the height of the sidewall of the drainage ditch on its side.
[0042] The anti-slip tenon 4 has an inverted trapezoidal cross section and a depth of 200-500mm.
[0043] It should be noted that the inverted trapezoidal cross section of the anti-slip tenon 4 described in this embodiment is only one optional implementation scheme. In other embodiments, a rectangular or other polygonal cross section can also be used to enhance the anti-slip force by increasing the bottom contact area, thereby improving the resistance of the anti-slip tenon 4 to the soil.
[0044] As an optional implementation, the anti-slip tenon 4 is provided with a first fixing member 10. The anti-overturning toe plate 5 is provided with a second fixing member 11.
[0045] Both the first fixing member 10 and the second fixing member 11 can use anchor bolts, which are fixedly installed at the bottom of the anti-slip tenon 4 and the anti-overturning toe plate 5 by cement pouring.
[0046] The anchor rods are multiple. In this embodiment, the anchor rods at the bottom of the anti-slip tenon 4 are arranged in 3 rows, with 3 rods in each row, evenly distributed along the extension direction of the anti-slip tenon 4. Anchor rods are also provided at the bottom and on the outward side of the anti-overturning toe plate 5.
[0047] As an optional implementation, the bottom plate 1 (1) of the drainage ditch is provided with an L-shaped anchor plate 9 at one end near the second drainage ditch, and the protrusion of the L-shaped anchor plate 9 faces the side away from the bottom plate 1 of the drainage ditch.
[0048] When used in conjunction with the anti-slip tenon 4, it further enhances the anti-overturning ability and achieves a balance of lever arms on both sides of the drainage ditch bottom plate 1.
[0049] As an optional implementation, the drainage ditch bottom plate 1, the first drainage ditch sidewall 2, and the second drainage ditch sidewall 3 form a U-shaped trough, and the inner surface of the U-shaped trough is coated with a waterproof coating 6.
[0050] In the above, the waterproof coating 6 can be made of polyurethane waterproof coating. As a common polymer waterproof coating, polyurethane waterproof coating has good wear resistance, water resistance and tensile strength. It has high tensile strength, can adapt to the slight deformation that may occur in the drainage ditch during use, is not easy to crack, ensures waterproof effect, can be applied on damp base surface, has strong adaptability to the damp environment that may exist in the drainage ditch, and the waterproof membrane formed after curing has a certain elasticity, which can effectively resist water penetration.
[0051] Optionally, the thickness of the waterproof coating 6 in this embodiment is 2-4 mm.
[0052] In summary, the working principle of this embodiment is as follows:
[0053] In use, the anti-slip drainage ditch structure at the toe of the slope is installed on the natural ground 8. Slope soil is filled above the anti-overturning toe plate 5, and the anti-slip tenon 4 is embedded in the soil. When the active earth pressure generated by the slope 7 on the left side of the first drainage ditch sidewall 2 pushes the drainage ditch structure to slide to the right, the anti-slip tenon 4 embedded in the soil will be resisted by the soil. The anti-slip tenon 4 is equipped with a tenon steel reinforcement skeleton 401, which makes it less prone to cracking under greater resistance, thus providing sufficient sliding resistance to prevent the drainage ditch structure from sliding to the right. An anti-overturning toe plate 5 is installed on the side of the drainage ditch bottom plate 1 closest to the first drainage ditch sidewall 2. When the active earth pressure generated by the slope 7 on the left side causes the drainage ditch structure to rotate clockwise... When the ditch tends to rotate, the weight of the fill slope soil pressing on the anti-overturning toe plate 5 will generate a resistance force opposite to the rotation trend, preventing the drainage ditch from rotating clockwise. The anti-overturning toe plate 5 is equipped with a toe plate steel reinforcement skeleton 501, which enhances the strength of the anti-overturning toe plate 5 and prevents the anti-overturning toe plate 5 from cracking due to excessive resistance, thus ensuring its stable anti-overturning function. A waterproof coating 6 with a thickness of 2-4mm is applied to the inner surface of the drainage ditch bottom plate 1, the first drainage ditch side wall 2, and the second drainage ditch side wall 3. The waterproof coating 6 can effectively prevent water from penetrating into the drainage ditch structure, avoiding problems such as soil softening and reduced structural strength caused by water infiltration, ensuring the stability of the soil environment in which the drainage ditch is located, indirectly enhancing the drainage ditch's resistance to sliding and overturning, and extending its service life.
[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application.
