TECHNICAL FIELD
[0001] The present application relates to the technical field of quick flow channel, in particular to a highway engineering quick flow channel. BACKGROUND
[0002] The quick flow channel refers to an artificial ditch with a slope greater than the critical slope, which is used to guide water flow under the condition of short distance and large water surface fall. In highway engineering, the quick flow channel is usually built on both sides of the slope road to drain water and slow down the water flow, thereby protecting the roadbed.
[0003] In the related art, a common quick flow channel is designed, which includes an inclined channel on the slope, a guide channel fixedly arranged at the top of the inclined channel, the guide channel being communicated with a water intercepting ditch or a platform drainage ditch, a horizontal channel fixedly arranged at the bottom of the inclined channel on the roadbed, the horizontal channel being communicated with a cut side ditch.
[0004] In the implementation of the present application, it is found that in the related art, at least the following problem exists: In the process of water flow flowing down from the inclined channel on the slope, a large amount of potential energy is converted into kinetic energy, and when the water flow flows into the cut side ditch, it will cause a violent impact on the cut side ditch, which may damage the structure of the cut side ditch. CONTENT OF THE UTILITY MODEL
[0005] In order to reduce the impact of water flow on the cut side ditch and protect the structure of the cut side ditch, the present application provides a highway engineering quick flow channel.
[0006] The highway engineering quick flow channel provided by the present application adopts the following technical scheme:
[0007] The highway engineering quick flow channel comprises an inclined channel on the slope, a guide channel fixedly arranged at the top of the inclined channel, the guide channel being communicated with a water intercepting ditch or a platform drainage ditch, a horizontal channel fixedly arranged at the bottom of the inclined channel on the roadbed, the horizontal channel being communicated with a cut side ditch, a plurality of water falling chops fixedly arranged on the inner bottom wall of the inclined channel, the water falling chops being distributed in a stepped manner along the length direction of the inclined channel, a flow resistance chop arranged on the inner bottom wall of the horizontal channel, and a water passing hole formed on the flow resistance chop along the length direction of the horizontal channel.
[0008] By adopting the above technical scheme, when the water flow flows down in the inclined channel, it will pass through the water falling chops distributed in a stepped manner in sequence, in the process, the flow rate of the water flow is reduced and the energy of the water flow is consumed, thereby reducing the impact on the horizontal channel. The flow resistance chop on the inner bottom wall of the horizontal channel further weakens the impact force of the water flow, and finally the water flow enters the cut side ditch after passing through the water passing hole or above the flow resistance chop, thereby effectively reducing the damage of the water flow to the cut side ditch and prolonging the service life of the cut side ditch.
[0009] Preferably, the outer side wall of the chute is further provided with a plurality of stepping platforms for the construction personnel to walk on.
[0010] By adopting the above technical scheme, the stepping platforms provide a safe and stable walking and working space for the construction personnel, facilitating the construction personnel to check, maintain and clean the chute, and ensuring the safety of the personnel during construction and maintenance.
[0011] Preferably, the upper surface of the stepping platform is integrally formed with a plurality of anti-skid protrusions.
[0012] By adopting the above technical scheme, the anti-skid protrusions further increase the friction of the surface of the stepping platform, making the construction personnel walk more stably on the stepping platform, reducing the risk of falling down, and improving the safety of construction and maintenance work.
[0013] Preferably, the length direction of the horizontal groove is provided with at least two baffle blocks, and the water passing holes on the adjacent baffle blocks are staggered in the width direction of the horizontal groove.
[0014] By adopting the above technical scheme, the multiple baffle blocks arranged at intervals and with staggered water passing holes can more fully disperse and weaken the impact force of the water flow, reduce the water flow entering the excavation side ditch directly from the water passing holes, make the water flow flow around the staggered water passing holes, and further consume the energy of the water flow in the horizontal groove, thereby more effectively reducing the damage of the water flow to the excavation side ditch and enhancing the energy dissipation effect of the chute.
[0015] Preferably, the baffle block comprises a horizontal part and a plurality of vertical parts, all the vertical parts are vertically and fixedly distributed on the bottom of the horizontal part in the width direction of the horizontal groove, a plurality of sockets are formed on the inner bottom wall of the horizontal groove, the bottom of the vertical part is inserted into the socket, and the water passing hole is formed by the adjacent two vertical parts, the horizontal part and the inner bottom wall of the horizontal groove.
[0016] By adopting the above technical scheme, the detachable installation structure of the baffle block facilitates individual replacement when the baffle block is damaged, reducing the maintenance cost and difficulty. At the same time, the setting of the socket allows the baffle block to slide in the vertical direction, and the length of the vertical part extending out of the socket is adjusted. When the water flow is large, the baffle block is lifted up, the volume of the vertical part extending out of the socket is increased, so as to increase the effective volume of the baffle block to hinder the water flow, thereby increasing the resistance to the water flow; when the water flow is small, the baffle block is lowered, the volume of the vertical part extending out of the socket is reduced, the through hole is adjusted, and the water flow is prevented from being lower than the bottom of the horizontal part, so as to prevent the water flow from flowing only through the through hole, and to ensure the resistance of the baffle block to the water flow.
[0017] Preferably, the two side walls of the horizontal groove are vertically provided with a set of adjusting lead screws at the top, and the adjusting lead screws are threadedly connected with connecting pieces fixedly connected with the side walls of the stilling basin.
[0018] By adopting the above technical scheme, rotating the adjusting lead screw can drive the connecting piece to move in the vertical direction, thereby adjusting the height of the stilling basin, and further realizing flexible adjustment of the size of the water passage, which can adapt to different water flow conditions, and further improves the applicability and drainage effect of the rapid flow groove.
[0019] Preferably, the two side walls of the horizontal groove are vertically provided with a set of adjusting lead screws at the top, and the adjusting lead screws are threadedly connected with connecting pieces fixedly connected with the side walls of the stilling basin.
[0020] By adopting the above technical scheme, the rotating ring and the threaded ring provide stable support and precise thread cooperation for the adjusting lead screw, ensuring that the adjusting lead screw can smoothly drive the connecting piece to move up and down when rotating, thereby effectively adjusting the height of the stilling basin, enhancing the reliability and stability of the adjusting device, and facilitating maintenance when the rotating ring, threaded ring and adjusting lead screw are damaged.
[0021] Preferably, the adjusting lead screw, rotating ring and threaded ring are made of metal.
[0022] By adopting the above technical scheme, the metal material has high strength and corrosion resistance, which can ensure the stability and durability of the adjusting lead screw, rotating ring and threaded ring during long-term use, reduce the maintenance and replacement cost caused by component damage, and improve the service life and reliability of the rapid flow groove as a whole.
[0023] In summary, the present application has at least one of the following beneficial technical effects:
[0024] 1. By arranging the stepped waterfalls and the stilling basin with water passages, the impact force of the water flow is gradually weakened, the damage of the water flow to the excavation side ditch is prevented as much as possible, the service life of the excavation side ditch is prolonged, and the highway maintenance cost is reduced.
[0025] 2. By arranging the stepping platform and the anti-skid convex points, a safe and stable working space is provided for the construction personnel to check, maintain and clean the rapid flow groove, which facilitates the construction personnel to reach each part to handle problems and ensures the normal operation of the rapid flow groove.
[0026] 3. By arranging the horizontal part, the socket and the vertical part inserted in the socket, the distance between the horizontal part and the inner bottom wall of the horizontal groove is changed by adjusting the length of the vertical part protruding from the socket, thereby enhancing the adaptability of the rapid flow groove to different working conditions and adapting to different water flow.

DETAILED DESCRIPTION
[0031] The following will be described in detail in combination with the accompanying Figures 1-3 The present application is further described in detail.
[0032] The embodiments of the present application disclose a highway engineering rapid flow tank. Referring to Figure 1 and Figure 3 , the chute 1 on the slope is fixedly provided with the guide groove 2 at the top, and the guide groove 2 is communicated with the water interception ditch or the platform drainage ditch. The horizontal groove 3 on the roadbed is fixedly provided at the bottom of the chute 1, and the horizontal groove 3 is communicated with the excavation side ditch. In the embodiments, the guide groove 2, the chute 1 and the horizontal groove 3 are all composed of a bottom edge and two side edges on both sides of the bottom edge, and are all poured by C30 cast-in-place concrete. A plurality of water drops 11 are fixedly provided on the inner bottom wall of the chute 1, and the water drops 11 are distributed in a stepped manner along the length direction of the chute 1. Specifically, the water drops 11 are integrally poured and formed with the chute 1. The flow brake 31 is arranged on the inner bottom wall of the horizontal groove 3, and the water passage 32 is formed on the flow brake 31 along the length direction of the horizontal groove 3.
[0033] Referring to Figure 1 and Figure 3 , when the water flows down in the chute 1, the water will pass through the water drops 11 distributed in a stepped manner in sequence, so as to reduce the flow rate of the water and consume the energy of the water. Then, the water flows into the horizontal groove 3 after being slowed down, and the flow brake 31 on the inner bottom wall of the horizontal groove 3 further weakens the impact force of the water, and finally the water enters the excavation side ditch after passing through the water passage 32 and above the flow brake 31.
[0034] In order to facilitate the inspection and maintenance of the rapid flow tank by the construction personnel, referring to Figure 1 and Figure 2The outer side wall of the chute 1 is provided with a plurality of stepping platforms 12 for the construction personnel to walk and step on. The upper surface of the stepping platform 12 is integrally formed with a plurality of anti-skid protrusions 121 for increasing friction.
[0035] In order to enhance the energy dissipation effect of the energy dissipation block 31, referring to Figure 1 and Figure 3 , the energy dissipation block 31 is arranged at intervals in the length direction of the horizontal groove 3, and in the embodiment, four energy dissipation blocks 31 are arranged. The water passing holes 32 on the adjacent energy dissipation blocks 31 are staggered in the width direction of the horizontal groove 3. The water flow passing through the water passing hole 32 of the energy dissipation block 31 cannot directly and continuously pass through the water passing holes 32 of the plurality of energy dissipation blocks 31, and the flow path of the water flow in the horizontal groove 3 is more complex, so that the energy of the water flow is more fully consumed, and the impact of the water flow on the excavation side ditch is further reduced.
[0036] In order to facilitate the adjustment of the energy dissipation effect of the energy dissipation block 31 and adapt to different water flow, referring to Figure 1 and Figure 3 , the energy dissipation block 31 includes a transverse portion 311 and a plurality of vertical portions 312. All the vertical portions 312 are vertically and fixedly distributed on the bottom of the transverse portion 311 along the width direction of the horizontal groove 3, and a plurality of sockets 33 are formed on the inner bottom wall of the horizontal groove 3. It is worth noting that the socket 33 cannot completely penetrate the inner bottom wall of the horizontal groove 3. The bottom of the vertical portion 312 is inserted into the socket 33, and the water passing hole 32 is formed by the adjacent two vertical portions 312, the transverse portion 311 and the inner bottom wall of the horizontal groove 3.
[0037] Referring to Figure 1 and Figure 3 , a group of adjusting lead screws 4 are vertically and rotatably arranged on the top of the two side walls of the horizontal groove 3. An adjusting block is threadedly connected to the adjusting lead screw 4, and the adjusting block is fixedly connected to the side wall of the energy dissipation block 31. Specifically, a rotating ring 41 is pre-buried on the top of the two side walls of the horizontal groove 3, a threaded ring 42 is embedded in the fixed block, the bottom of the adjusting lead screw 4 is rotatably matched with the rotating ring 41, the middle of the adjusting lead screw 4 is threadedly matched with the threaded ring 42, and a knob is further fixedly arranged on the top of the adjusting lead screw 4. The height of the energy dissipation block 31 is adjusted by rotating the knob to rotate the adjusting lead screw 4, so that the adjusting block moves in the vertical direction, thereby adjusting the height of the energy dissipation block 31. When the water flow is large, the energy dissipation block 31 is lifted to increase the volume of the vertical portion 312 extending out of the socket, so as to increase the effective volume of the energy dissipation block 31 to hinder the water flow, thereby increasing the resistance to the water flow. When the water flow is small, the energy dissipation block 31 is lowered to reduce the volume of the vertical portion 312 extending out of the socket, so as to reduce the through hole and prevent the water flow from being lower than the bottom of the transverse portion 311, thereby ensuring the resistance of the energy dissipation block 31 to the water flow.
[0038] Specifically, stainless steel material can be used. Stainless steel has good corrosion resistance and strength, and can maintain stable performance during long-term use, reducing maintenance and replacement costs due to component corrosion or damage.
[0039] The implementation principle of the highway engineering quick flow tank according to an embodiment of the application is as follows: in the process of drainage, the water flow in the water interception ditch or the platform drainage ditch first flows into the guide groove 2, and then smoothly enters the inclined groove 1 through the guidance of the guide groove 2. The water flow in the inclined groove 1 successively passes through the stepped waterfalls 11, and the flow rate is greatly reduced, and a large amount of energy is consumed. Then, the water flow flows into the horizontal groove 3 at a reduced speed, and the multiple energy dissipating baffles 31 in the horizontal groove 3 further dissipate the energy of the water flow, so that the flow path of the water flow in the horizontal groove 3 is more complex, and the energy of the water flow is more fully consumed. In addition, workers can adjust the height of the energy dissipating baffles 31 by rotating the knob to drive the adjusting lead screw 4 according to different water flow, so as to further reduce the impact of the water flow on the excavation side ditch. Finally, the water flow smoothly passes through the water flow holes 32 and above the energy dissipating baffles 31, and then enters the excavation side ditch, thereby reducing the damage of the water flow to the excavation side ditch and ensuring the stable operation of the highway drainage system. At the same time, the stepping platforms 12 and the anti-skid convex points 121 on the outer side wall of the inclined groove 1 provide safe and convenient inspection and maintenance conditions for construction personnel.
[0040] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
