Abstract
Description
Technical Field
[0001] This utility model belongs to the field of highway engineering technology, and specifically relates to a rapid flow channel for highway engineering. Background Technology
[0002] A chute is an artificial ditch with a slope greater than the critical slope, designed to guide water flow in situations with short distances and large water level differences. In highway engineering, chutes are often built on both sides of sloping roads to drain water and slow down the flow. They typically connect to the road surface's side ditches or serve directly as drainage outlets for road surface runoff. They can also quickly remove residual water from road cut slopes, preventing slope collapses, landslides, and debris flows caused by waterlogging, thus significantly protecting the highway subgrade. Therefore, the development of a suitable chute is crucial. However, in practical use, when the slope of the sloping ditch is large and the water flow is high, the water flows from the top to the bottom. During this process, the water's gravitational potential energy is converted into kinetic energy, increasing the water velocity and the impact force on the buffer ditch. Since the stress-relief structure is simple and the stress-relief time is short, the stress-relief effect is poor, which, over time, shortens the service life of the buffer ditch.
[0003] In view of this, in order to solve the above-mentioned technical problems, this utility model proposes a rapid flow channel that can sustainably dissipate energy from water flow, reduce water velocity and impact force, and extend the service life of buffer channels. Utility Model Content
[0004] This utility model provides a rapid flow channel for highway engineering that can continuously dissipate energy from water flow, reduce water velocity and impact force, and extend the service life of the buffer channel. The specific solution is as follows: A rapid flow channel for highway engineering includes a diversion channel section, an inclined channel section, and a buffer channel section connected sequentially from top to bottom. The inclined channel section has a plurality of energy dissipation cones spaced apart along its length. The left and right side walls of the inclined channel section have a plurality of energy dissipation plates spaced apart, and the energy dissipation plates are inclined toward the middle of the inclined channel section. The buffer channel section is vertically connected to a buffer well. The buffer well has a scour protection plate vertically arranged along the water flow direction, and the scour protection plate has a plurality of permeable holes spaced apart.
[0005] Furthermore, the buffer well is vertically fixedly connected to the left and right side walls respectively, and the anti-impact plate is slidably disposed between the two sliding grooves. The top of the anti-impact plate is higher than the inner surface of the buffer groove section and lower than the upper end surface of the groove wall.
[0006] Furthermore, outer edge plates are fixedly connected to the two outer sides of the drainage trench section, the inclined trench section and the buffer trench section, and side wall plates are provided vertically upward on both sides of the outer edge plates.
[0007] Furthermore, a filter frame is provided on one side of the inclined trench section inside the buffer well, and pads for placing the filter frame are provided on both sides of the bottom of the buffer well. The upper outer periphery of the filter frame is attached to the side wall of the buffer well and the anti-impact plate, and the lower outer periphery is spaced apart from the buffer well and the anti-impact plate.
[0008] Furthermore, hooks are vertically connected to the left and right sides of the filter frame, and the two hooks are respectively hung on the two side wall panels.
[0009] Furthermore, the bottom surface of the inclined trench section is fixed with multiple fixed steps at intervals along its length.
[0010] Furthermore, the surfaces of the inclined groove section and the buffer groove section are both rough surface structures.
[0011] Furthermore, multiple energy dissipation grooves are spaced apart on the buffer trench section on the side of the buffer well away from the inclined trench section.
[0012] Furthermore, the drainage channel section is a funnel-shaped structure with an open front section, and a guide plate is connected at the connection between the drainage channel section and the inclined channel section, and its inclination angle is smaller than that of the inclined channel section.
[0013] The beneficial effects of this utility model are: This utility model discloses a rapid flow channel for highway engineering. By installing several energy-dissipating cones on the surface of the inclined channel section, several energy-dissipating plates on both sides, and a buffer well with an anti-scour plate inside, when water flows down the inclined channel section, the energy-dissipating cones and plates dissipate energy, slowing down the flow velocity and impact force of the water. The anti-scour plate further impedes the flow before it enters the buffer well, further reducing the impact force of the water, thereby improving the energy dissipation effect and extending the service life of the buffer channel section. By installing a filter frame in the buffer well, large impurities in the water can be collected uniformly to avoid accumulation and blockage, thus improving the drainage efficiency of the drainage ditch and providing a certain degree of protection for the foundation of the highway slope.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] See Figure 1-5 A rapid flow channel for highway engineering includes a diversion channel section 1, an inclined channel section 2, and a buffer channel section 3 connected sequentially from top to bottom. Several energy dissipation cones 4 are spaced along the length of the inclined channel section 2. Several energy dissipation plates 5 are spaced on the left and right side walls of the inclined channel section 2. These energy dissipation plates 5 are spaced apart in the middle and lower sections of the inclined channel section 2. When water flows past the energy dissipation plates 5, it is redirected to flow past the energy dissipation cones 4. This repeated process further improves the energy dissipation effect. The energy dissipation plates 5 are inclined towards the middle of the inclined channel section 2. The buffer channel section 3 is vertically connected to a buffer well 6. A scour protection plate 7 is vertically installed in the buffer well 6 along the water flow direction. Several permeable holes are spaced apart on the scour protection plate 7.
[0022] The preferred buffer well 6 has vertically fixed grooves 8 on its left and right side walls respectively, and the anti-impact plate 7 is slidably set between the two grooves 8. The top of the anti-impact plate 7 is higher than the inner surface of the buffer groove section 3 and lower than the upper end surface of the groove wall. The buffer well 6 can be cleaned by removing the anti-impact plate 7.
[0023] The preferred diversion channel section 1, inclined channel section 2 and buffer channel section 3 are respectively fixedly connected to the outer edges of the two sides of the channel. The outer edge plate 9 can increase the contact area between the two sides of the channel and the slope, thus making the rapid flow channel more stable on the slope. The outer edge plates 9 on both sides are respectively provided with side wall plates 10. The side wall plates 10 can effectively prevent water from overflowing from both sides of the rapid flow channel and impacting and soaking the slope when the water flow is large, thereby preventing the slope from collapsing.
[0024] A filter frame 11 is provided on one side of the inclined ditch section 2 inside the preferred buffer well 6. Pads 12 for placing the filter frame 11 are provided on both sides of the bottom of the buffer well 6. The upper outer periphery of the filter frame 11 is attached to the side wall of the buffer well 6 and the anti-impact plate 7, and the lower outer periphery is spaced apart from the buffer well 6 and the anti-impact plate 7. The combined design of the buffer well 6, the anti-impact plate 7 and the filter frame 11 can not only reduce the impact force of the water, but also collect large impurities to avoid accumulation and blockage, thereby improving the drainage efficiency of the drainage channel.
[0025] The preferred filter frame 11 has hooks 13 vertically connected to its left and right sides respectively. The two hooks 13 are respectively hung on the two side wall panels 10. The hooks 13 can be used to remove the filter frame 11 when cleaning, saving time and effort.
[0026] The bottom surface of the preferred inclined ditch section 2 is fixed with a plurality of fixed steps 14 at intervals along its length. The fixed steps 14 can increase the contact area between the inclined ditch section 2 and the slope, thereby making the rapid flow channel more firmly installed on the slope.
[0027] The preferred inclined trench section 2 and buffer trench section 3 have rough surface structures, which can effectively dissipate energy in the water and reduce the flow velocity of the water.
[0028] The preferred buffer well 6 has multiple energy dissipation channels 15 spaced apart on the buffer ditch section 3 on the side opposite to the inclined ditch section 2. The multiple energy dissipation channels 15 allow water to flow downward from the energy dissipation channels 15 into the drainage ditch, thereby achieving water diversion and further improving the energy dissipation effect.
[0029] The preferred drainage channel section 1 is a funnel-shaped structure with an open front section. A guide plate 16 is connected at the connection between the drainage channel section 1 and the inclined channel section 2, and its inclination angle is smaller than that of the inclined channel section 2.
[0030] The working principle of this utility model: First, when the water enters from the diversion channel section 1, it flows through the inclined channel section 2 and then through the buffer channel section 3. During this process, when the water passes through several energy dissipation cones 4 and several energy dissipation plates 5, the repeated combination of energy dissipation cones 4 and energy dissipation plates 5, as well as the rough surfaces of the inclined channel section 2 and the buffer channel section 3, can slow down the flow rate and achieve energy dissipation. When the water flows through the buffer well 6 of the buffer channel section 3, it is further dissipated by the anti-scour plate 7 inside and enters the buffer well 6. The water emerges from the buffer well 6 or flows out from the top of the anti-scour plate 7. During this process, large impurities (such as stones and sand) carried in the water can be retained in the filter frame 11, thereby avoiding accumulation and blockage and improving the drainage efficiency of the drainage channel. Finally, the water flows into the drainage channel from the ends of multiple energy dissipation channels 15 or the buffer channel section 3. When cleaning the large impurities in the filter frame 11, the worker only needs to lift the filter frame 11 by hand using the hook 13.
