Description

Technical Field

[0001] This utility model relates to the field of open channel support technology, specifically a support structure for an urban landscape open channel. Background Technology

[0002] An open channel is a channel with a free surface for water flow. The flow in an open channel is a flow where the water partially comes into contact with the atmosphere and has a free surface.

[0003] In the construction of open channel slope protection, precast slabs are commonly used support materials. Their core function is to reinforce the slope and prevent soil collapse and erosion. However, in the current construction process, drainage structures are often not reserved in advance when the precast slabs are laid. This design defect will bring obvious hidden dangers during the rainy season. Rainwater directly washes the precast slabs on the slope surface. Over time, rainwater that is not drained in time will continue to accumulate and gradually seep into the soil below the slabs, causing the soil moisture content to increase and the strength to decrease. This may eventually lead to soil collapse, seriously affecting the stability of the open channel slope protection and even destroying the protective effect of the entire support system. Utility Model Content

[0004] The purpose of this utility model is to provide a support structure for urban landscape open channels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support structure for an urban landscape open channel, comprising the open channel body, and further comprising: A precast slab fixed to the surface of the open channel body, the surface of the precast slab is provided with multiple drainage grooves, and the surface of the drainage grooves is provided with flow guides to facilitate the drainage process. The flow guides include protective covers, which are disposed on the surface of the drainage grooves.

[0006] Preferably, positioning plates are fixedly connected to both sides of the surface of the protective cover, and the surface of the positioning plates is provided with through holes.

[0007] Preferably, a positioning rod is slidably inserted into the inner cavity of the through hole, and the bottom of the positioning rod is fixedly connected to the precast slab.

[0008] Preferably, both sides of the top of the positioning rod are rotatably connected to inclined baffles, and the bottom of the inclined baffles is in contact with the positioning plate.

[0009] Preferably, springs are fixedly connected to both sides of the positioning rod, and one side of each spring is fixedly connected to the inner wall of the inclined baffle.

[0010] Preferably, a partition is fixedly connected to the rear end face of the precast slab, and the rear end face of the partition is fixedly connected to the open channel body.

[0011] Preferably, each of the four corners of the bottom of the protective cover is fixedly connected with a plug rod, and the plug rod is inserted into the inner cavity of the partition.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention enables the orderly discharge of rainwater and other water bodies through the design of the flow guide. After collecting rainwater from the slope through the drainage channel, it is directly guided into the water flow of the open channel body, avoiding rainwater accumulation and infiltration. At the same time, the protective cover equipped with the flow guide can constrain the discharged water flow inside, effectively controlling the direction and velocity of the water flow, preventing uncontrolled discharge and slope erosion due to excessive water flow. In addition, the protective cover can be installed and disassembled by the fit between the inclined baffle and the positioning plate. When the inner wall of the protective cover absorbs mud and debris carried by rainwater due to long-term use, affecting the water flow discharge efficiency, it can be easily removed for cleaning, ensuring that the drainage channel is always unobstructed and guaranteeing the stability of the support system.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 4 As shown, a support structure for an urban landscape open channel includes the open channel body 1, and also includes: The precast slab 2 is fixed on the surface of the open channel body 1. The surface of the precast slab 2 is provided with multiple drainage grooves 3. The surface of the drainage grooves 3 is provided with guides 4 to facilitate the drainage process. The guides 4 include protective covers 401, which are provided on the surface of the drainage grooves 3.

[0017] Positioning plates 402 are fixedly connected to both sides of the surface of the protective cover 401. Through holes 403 are formed on the surface of the positioning plates 402. A positioning rod 404 is slidably inserted into the inner cavity of the through holes 403. The bottom of the positioning rod 404 is fixedly connected to the precast slab 2. Inclined baffles 405 are rotatably connected to both sides of the top of the positioning rod 404. The bottom of the inclined baffles 405 is in contact with the positioning plates 402. Springs 406 are fixedly connected to both sides of the positioning rod 404. One side of the protective cover 406 is fixedly connected to the inner wall of the inclined baffle 405. The four corners of the bottom of the protective cover 401 are fixedly connected to insert rods 407, which are inserted into the inner cavity of the partition 5. When it is necessary to achieve orderly discharge of rainwater and other water bodies, first align the protective cover 401 with the outlet of the drainage trough 3, ensuring it fits tightly against the surface of the partition 5. Then, insert the insert rods 407 into the pre-drilled holes in the partition 5 to complete the initial positioning of the protective cover 401, avoiding installation... During the process, the protective cover 401, along with the positioning plate 402, is inserted into the positioning rod 404, so that the positioning rod 404 passes through the through hole 403 on the positioning plate 402. During the insertion process, the positioning plate 402 will contact the inclined baffle 405. As the insertion depth increases, the inclined baffle 405 closes inward around the axis of rotation, while the spring 406 is compressed to retract and store force. When the positioning plate 402 is fully inserted, the retracted spring 406 releases its elasticity and extends, causing the inclined baffle 405 to reset and unfold. At this time, the bottom of the inclined baffle 405 is tightly attached to the lower surface of the positioning plate 402, forming a solid locking structure, which stably fixes the positioning plate 402 on the positioning rod 404. The protective cover 401 is accurately and firmly fixed at the outlet of the drainage channel 3, thereby effectively constraining the direction and velocity of the discharged water flow, avoiding uncontrolled discharge due to excessive water flow, and thus preventing water flow from eroding the slope and ensuring the stability of the open channel support system.

[0018] A partition 5 is fixedly connected to the rear end face of the precast slab 2, and the rear end face of the partition 5 is fixedly connected to the open channel body 1. The partition 5 provides positioning support for the installation of the precast slab 2 into the open channel body 1, making the installation operation more convenient and efficient. On the other hand, it can tightly fill the gap between the precast slab 2 and the open channel body 1, forming a reliable sealing structure, effectively blocking rainwater and other water stains from seeping into the soil layer under the slab, avoiding softening and collapse of the soil due to increased water content, and ensuring the stability of the open channel slope support.

[0019] Working principle: First, the precast slab 2 is installed on the open channel body 1. Then, the partition plate 5 provides positioning support for the installation of the precast slab 2 onto the open channel body 1, making the installation operation more convenient and efficient. On the other hand, it can tightly fill the gap between the precast slab 2 and the open channel body 1, forming a reliable sealing structure, effectively preventing rainwater and other water stains from seeping into the soil layer below the slab, avoiding softening and collapse of the soil due to increased moisture content, and ensuring the stability of the open channel slope support. Next, the protective cover 401 is aligned with the outlet of the drainage channel 3. Position the protective cover 401 so that it fits tightly against the surface of the partition 5. Then, insert the insertion rod 407 into the reserved hole in the partition 5 to complete the initial positioning of the protective cover 401 and prevent displacement during installation. Next, fit the protective cover 401 together with the positioning plate 402 onto the positioning rod 404, so that the positioning rod 404 passes through the through hole 403 on the positioning plate 402. During the insertion process, the positioning plate 402 will contact the inclined baffle 405. As the insertion depth increases, the inclined baffle 405 moves inward around the rotation axis. The spring 406 is compressed and retracted to store energy as the positioning plate 402 is fully inserted. Once the positioning plate 402 is fully inserted, the retracted spring 406 releases its force and extends, causing the inclined baffle 405 to reset and unfold. At this point, the bottom of the inclined baffle 405 is tightly fitted with the lower surface of the positioning plate 402, forming a secure locking structure that stably fixes the positioning plate 402 to the positioning rod 404. The protective cover 401 is precisely and securely fixed to the outlet of the drainage channel 3, effectively constraining the direction and velocity of the discharged water flow and preventing... To prevent excessive water flow from causing uncontrolled discharge and thus prevent water erosion of the slope, ensuring the stability of the open channel support system, if it is necessary to disassemble and clean the protective cover 401, the inclined baffle 405 is rotated using the pivot and the spring 406 is compressed and retracted inward. Then the bottom of the inclined baffle 405 is separated from the surface of the positioning plate 402. At that time, the positioning plate 402 and the protective cover 401 can be pulled upward, so that the protective cover 401 can be quickly disassembled and cleaned.
