Description

Technical Field

[0001] This utility model relates to the field of highway engineering, and in particular to a highway subgrade anti-slip device. Background Technology

[0002] In highway construction in mountainous and other complex terrain areas, roadbed landslides are a common geological hazard. Traditional protective measures, such as retaining walls and anti-slide piles, have drawbacks such as high construction difficulty, high cost, and significant environmental damage, and their effectiveness is limited when dealing with complex geological conditions.

[0003] Patent CN222375458U discloses a highway subgrade slope anti-slip device. In this patent, a top beam and a bottom beam are pre-embedded at the top and root of the slope, respectively, and several drainage channels are laid on the slope surface. The top beam has several outlets along its side, and the bottom beam has several drainage outlets along its side. The two ends of the drainage channels are connected to the outlets and drainage outlets, respectively. Several support frames are also laid on the slope surface, with their ends abutting against the bottom beams. The support frames and drainage channels are distributed alternately, and multiple partition plates extend upwards from the top surface of the support frames, with the tops of the partition plates abutting against the top beams. The top beam, bottom beam, and drainage channels are all precast concrete components. These precast concrete components, delivered from the factory, can be directly laid, significantly shortening the construction period. The precast concrete components have high structural strength and a long service life. The top beam, bottom beam, and drainage channels can form a skeleton structure, effectively restraining the slope soil and resulting in a significant anti-slip effect.

[0004] However, the patent still reveals several shortcomings in practical applications. Specifically, firstly, the lack of a slope runoff collection device leads to direct scouring of the slope by surface runoff during rainfall, and continuous hydraulic action can easily cause soil softening, resulting in roadbed instability; secondly, the drainage ditch is only connected to the top and bottom beams by a simple abutment method, resulting in insufficient shear strength at the joints, which can easily lead to displacement under extreme working conditions, causing drainage failure and thus reducing overall stability. Utility Model Content

[0005] The present invention aims to provide a roadbed anti-slip device to overcome the shortcomings mentioned above.

[0006] To achieve the above objectives, the technical solution of this utility model is: a highway subgrade anti-slip device, comprising:

[0008] Multiple water diversion channels are laid at an angle on the slope surface and used to connect the water collection channel and the drainage channel.

[0009] A support frame is fixedly installed between two adjacent water diversion channels in the horizontal direction. Water inlets are provided on the side wall of the water diversion channel near the support frame. The support frame is used to guide water from the slope surface into the water inlets.

[0015] Furthermore, a third connecting block is integrally formed on the lower surface of the water collection tank. The third connecting block is configured one-to-one with the water diversion tank it is connected to. Two right-angle connectors are fixedly connected to one end of the third connecting block near the side wall of the water diversion tank. The other end of the right-angle connectors is connected to the upper end of the water diversion tank above through a through third fastener.

[0016] Furthermore, the front and rear sides of the third connecting pier are fixedly embedded with second steel plate connectors. One end of the second steel plate connector, the third connecting pier, and the right-angle connector is connected by a fourth connector that passes through. The other end of the right-angle connector is provided with two first strip-shaped through holes. The two third fasteners are respectively installed through the two first strip-shaped through holes and the upper end of the water diversion channel above.

[0017] The upper surface of the water collection tank is provided with a sieve plate, and the sieve plate is provided with sieve holes.

One end of the drain pipe 13 protrudes from the water collection tank 1 and is located above the upper water inlet trough 3, used to drain the water in the water collection tank 1. Since one end of the drain pipe 13 protrudes from the water collection tank 1, in order to facilitate transportation and avoid damage to the drain pipe 13, the drain support 12 and the water collection tank 1 are detachably connected, and are transported separately during transportation. In addition, in order to improve the sealing performance when the drain support 12 and the water collection tank 1 are connected, an asphalt bonding layer (not shown in the figure) is applied between the drain support 12 and the water collection tank 1.

[0036] The cross-section of the water inlet channel 3 is "U" shaped. The outer walls of the two adjacent water inlet channels 3 are embedded in the same channel steel connector 6 and are fixedly connected to the channel steel connector 6 by a through-through first fastener 7. Angle steel connectors are pre-embedded at the edges of the outer walls at both ends of the water inlet channel 3. The first fastener 7 is set through the angle steel connector located inside the channel steel connector 6 to ensure the stability of the connection.

[0037] Preferably, the support frame 4 is an upwardly convex arc shape, which can guide water into the inlet 5. Second connecting blocks 10 are integrally formed on the lower surfaces of both ends. The arc-shaped design of the support frame 4 not only guides water into the inlet 5, but also, through the cooperation of the first connecting blocks 8 and the second connecting blocks 10, further enhances the overall structural integrity, avoiding displacement or drainage failure under extreme working conditions. The lower surface of the water channel 3 is integrally formed with the first connecting block 8, and the first connecting block 8 and the second connecting block 10 are fixedly connected by a through-type second fastener 11.

[0042] This device collects water from the top of the slope via a collection tank 1 and guides the water to a drainage trough 2 via a water inlet trough 3 for discharge. The connection structure between the support frame 4 and the water inlet trough 3 ensures the stability and reliability of the device. The design of the screen plate 19 and the drainage pipe 13 effectively prevents debris from clogging the system and ensures smooth drainage. A stop plate 27 is installed at the bottom of the drainage trough 2. The stop plate 27 is inserted into the bottom of the slope to effectively fix the drainage trough 2, preventing displacement of the device during use and ensuring the long-term effectiveness of the drainage function.
