[0002] In the prior art, drainage channel construction can generally be excavated using an excavator to form a cross-sectional structure that is wide at the top and narrow at the bottom. After excavation, inclined slopes are formed on both sides of the drainage channel. The slopes generally need to be reinforced with concrete to prevent collapse in the later stage. In the actual construction process, some drainage channels will have a large amount of water at the bottom during the excavation process (or after excavation), which will lead to the formation of mud at the bottom of the drainage channel during the slope reinforcement construction. In order to facilitate the slope reinforcement construction, it is often necessary to remove the mud at the bottom of the drainage channel before construction can be carried out, which is time-consuming and thus leads to delays in the construction progress.

[0024] In an exemplary embodiment, Figure 1-3 As shown, this embodiment provides a mud mixture injection system, which can be used for drainage channel slope reinforcement construction, and includes a collection component for collecting mud, a batching component for receiving mud and adding a coagulant for mixing, a stirring component for stirring mud and a coagulant to form a injection material, and an injection component for injecting the injection material in a pressurized manner; and also includes a feeding component that allows the material to circulate between the collection component, the batching component, the stirring component and the injection component.

[0025] In another embodiment, a drainage ditch slope reinforcement construction method is provided, comprising the steps of: collecting mud at the bottom of the drainage ditch, and then adding a coagulant to mix, the coagulant can be cement, and the cement grade and specific addition amount can be adjusted according to actual needs. For example, if the water content of the mud is too high, additional dry soil or fine sand can be added, and dry soil can be given priority to using local materials. If the water content of the mud is too low, water can be added appropriately (generally, the mud can be successfully collected and there will be no situation where the water content is too low). After mixing, a shotcrete similar to concrete is formed, which is sprayed onto the slope to be reinforced at a pressure of 0.5-0.7MPa, and when the sprayed shotcrete covers the slope from the upper end to the lower end, it can be smoothed, such as when the shotcrete covers a coverage range of 0.5-2m (i.e., a width of 0.5-2m and a height of the coverage range from the upper end to the lower end of the slope), it is smoothed.

[0026] During the entire construction process, local materials are used and there is no need to additionally process the mud at the bottom of the drainage ditch, ensuring smooth construction without increasing additional construction costs. Therefore, the problem of reduced efficiency and increased cost of slope reinforcement construction due to mud formed at the bottom of the drainage ditch in the prior art is well solved.

Among them, the set injection component includes a jet pump 1 and a spray pipe 2 connected to the jet pump 1. The injection pipe 2 can be a hose with a longer length, and a handheld nozzle 3 is installed at the end of the hose to facilitate the operator to perform the injection operation.

[0028] like Figure 1-4As shown, in a further scheme, the injection system also includes a mobile box 4, a walking mechanism 5 is provided at the bottom of the mobile box 4, which can be a crawler, the batching component includes a batching box 9 fixed in the mobile box 4, the stirring component includes a stirring box 10 fixed in the mobile box 4, the injection component includes a jet pump 1 and a spray pipe 2 connected to the jet pump 1, the feeding component includes a feeding box 11 fixed in the mobile box 4 and a feeding belt 12 installed on the feeding box 11, the batching box 9 and the stirring box 10 are arranged side by side above the feeding box 11, the upper belt surface of the feeding belt 12 extends horizontally from the bottom of the batching box 9 to the bottom of the stirring box 10, and the lower belt surface of the feeding belt 12 faces the feeding box, and a return channel is also provided between the feeding box 11 and the batching box 9. 13, the pump inlet pipe 14 of the jet pump 1 extends into the feed box 11, and the pump outlet pipe is connected to the jet pipe 2, and the collection component includes an inclined screw conveyor 6, and a mud inlet port 7 is provided at the lower end, and a mud outlet is provided at the upper end, and a material guide box 8 connected to the mud outlet is fixedly connected to the screw conveyor 6, and the material guide box 8 is fixedly connected to the batching box 9, wherein the batching box 9 is also provided with a batching hopper 15, and the walking mechanism 5 can be a pair of located on both sides of the screw conveyor 6, that is, a pair of crawlers located on both sides of the screw conveyor 6 are provided at the bottom of the mobile box 4, and during construction, the screw conveyor 6 absorbs the mud at the front end, and the amount of mud at the bottom of the drainage channel is reduced, and the crawlers can walk more smoothly at the bottom of the drainage channel;The mobile box body 4 provides a direct installation foundation for the feeding box 11, and the batching box 9 and the mixing box 10 are fixed on the feeding box 11, and the batching box 9 and the mixing box 10 are in a connected state. The screw conveyor 6 is also fixedly connected to a guide box 8 connected to the mud outlet, and the guide box 8 is fixedly connected to the batching box 9, wherein a batching hopper 15 is also fixedly arranged on the batching box 9, and the screw conveyor 6 sends the mud to the guide box 8, and the coagulant (or other materials, such as water or dry soil that need to be added) is introduced through the batching hopper 15 and enters the batching box 9 below with the guide box 8. A vertical installation shaft 16 is also rotatably arranged at the bottom of the batching box 9, and the vertical installation shaft 16 is arranged vertically. The mounting shaft 16 extends vertically and rotates to the upper end of the batching box 9 and is connected to a first drive motor 17 that drives it to rotate. The lower end of the vertical mounting shaft 16 is close to the bottom of the batching box 9 and is installed with a first stirring blade 18. The first stirring blade 18 includes a plurality of blades equidistantly surrounding the vertical mounting shaft 16. When the first drive motor 17 rotates, the first stirring blade 18 can provide stirring for the material, so that the material can be preliminarily mixed. At the same time, the return channel 13 is located directly below the vertical mounting shaft 16. During the stirring process, the first stirring blade 18 will provide an upward lifting force so that the material passes through the return channel 13 and enters the bottom of the first stirring blade 18 upward. Then, as the first stirring blade 18 rotates, it smoothly enters the batching box 9. At the same time, the vertical installation shaft 16 is located outside the end of the feeding belt 12 located in the batching box 9. In this way, the first stirring blade 18 also enables the material to move toward the mixing box 10 during the rotation process. Combined with the operation of the feeding belt 12, the material preliminarily mixed in the batching box 9 can be moved to the mixing box 10. A transverse installation shaft 19 located above the feeding belt 12 is also rotatably installed in the mixing box 10. One end of the transverse installation shaft 19 rotates and extends outside the mixing box 10 and is connected to a second drive motor. The end of the transverse installation shaft 19 that is away from the second drive motor is fixedly connected to the second stirring The blade 20, when the second driving motor is running, can drive the second stirring blade 20 to stir and mix the material for the second time. The second stirring blade 20 can be a plurality of blades with a spiral structure and arranged equidistantly, so that a better stirring effect can be achieved. At the same time, a conveying rib 21 is also convexly provided on the outer wall of the conveyor belt 12. During the operation, these conveying ribs 21 make a circular motion with the conveyor belt 12 (the direction is from the batching box 9 to the mixing box 10), which can assist in pulling the material, and the material moves faster and can also provide a mixing effect on the material. The second stirring blade 20 above further improves the material mixing efficiency;More specifically, a mounting frame 22 is provided on the top of the feeding box 11 for mounting the feeding belt 12. Specifically, an active roller 23 and a driven roller 24 located at both ends are rotatably mounted in the mounting frame 22. The inner ring of the feeding belt 12 is provided with meshing teeth. The active roller 23 and the driven roller 24 are also provided with meshing teeth meshing with the feeding belt 12, so that the feeding belt 12 is wound around the active roller 23 and the driven roller 24 in a meshing manner, wherein one end of the active roller 23 rotates and extends into the moving box body 4 (that is, extends to the outside of the batching box 9, the mixing box 10 and the feeding box 11) and is connected to a third driving motor for driving it to rotate. The operation of the third driving motor causes the active roller 23 to rotate, thereby causing the feeding belt 12 and the driven roller 24 to rotate through meshing, so that the feeding belt 12 can be operated, and the material is pushed by the first stirring blade 18 and pulled by the feeding belt 12 to move toward the mixing box 10, and then the material is moved to the mixing box 10. During the process, some materials pass through the gap between the installation frame 22 and the feeding belt 12 (there is a gap between the feeding belt 12 and the installation frame 22 to ensure the normal operation of the feeding belt 12, and the conveying ribs 21 can also pass smoothly, and the materials can pass downward. During the downward process, the conveying ribs 21 can also pull the materials downward, so that the materials at the end of the installation frame 22 away from the first stirring blade 18 move downward faster) to the feeding box 11 below, and then return to the batching box 9 through the return channel 13, so as to form a material stirring cycle. After a period of cyclic stirring, the materials are mixed into uniform injection materials, and then injected through the injection pump 1; in a further detailed scheme, the pumping pipe 14 of the injection pump 1 extends into the feeding box 11, and the lower end of the pumping pipe 14 contacts the bottom of the feeding box 11, and a plurality of notches 25 are provided on the lower end surface of the pumping pipe 14 for the injection materials to enter smoothly. ;

[0029] like Figure 1-4As shown in the more detailed scheme, a pair of guide plates 35 are fixedly installed on the inner bottom surface of the batching box 9, and the guide plates 35 include a transverse plate 26 and a longitudinal plate 27 fixedly connected thereto and enclosed in an L shape, and the two transverse plates 26 are arranged opposite to each other, and the two longitudinal plates 27 are arranged opposite to each other, and the two longitudinal plates 27 are located on one side of the two transverse plates 26 and are parallel to the running direction of the conveyor belt 12. The first stirring blade 18 and the return channel 13 are both located between the two transverse plates 26, and the transverse plate 26 is opposite to the end of the conveyor belt 12. When the first drive motor 17 is running, the first stirring blade 18 rotates so that the material can The material can enter between the two transverse plates 26 from the side where the longitudinal plates 27 are not provided, and then leave from the side where the two longitudinal plates 27 are provided, and when leaving, it is thrown out by the first stirring blade 18 in the direction oblique to the conveyor belt 12, thereby pushing the material to move in the direction of the mixing box 10. In further detail, an arc-shaped plate 28 located above the two transverse plates 26 is fixedly connected, and a mounting hole is opened on the arc-shaped plate 28. The vertical mounting shaft 16 rotates through the mounting hole and extends to the bottom of the arc-shaped plate 28, and all the first stirring blades 18 are located below the arc-shaped plate 28. In this way, the arc-shaped plate 28 and the two transverse plates 26 are connected. The transverse plate 26 and the inner bottom surface of the batching box 9 enclose an arched channel 29 with a closed bottom. The first stirring blade 18 runs in the arched channel 29, stirring and mixing the material in the arched channel 29 while allowing the material to pass between the two transverse plates 26, thereby improving the efficiency of the preliminary mixing. Furthermore, due to the arrangement of the two longitudinal plates 27 at one end of the arched channel 29, the outlet of the material leaving the arched channel 29 is larger, so that the material entering the arched channel 29 from the return channel 13 can also be smoothly discharged and mixed with the material in the batching box 9 during the process; In another embodiment, the two longitudinal plates 27 can also be arranged to be inclined so that a trumpet-mouth structure is formed at the outlet of the arched channel 29 (i.e., the end away from the arched channel 29 is larger), so that the material has a guiding effect during the export process, and the process is smoother; in further detail, the lower end of the vertical mounting shaft 16 can continue to extend downward and pass through the return channel 13 into the feed box 11, while fixing the lifting screw 30 that surrounds the lifting material, so that it can cooperate with the first stirring blade 18 to make the material return from the feed box 11 to the batching box 9 more smoothly.

[0030] like Figure 1-4As shown, in a further detailed scheme, the screw conveyor 6 includes a conveying pipe 31 fixedly connected to the material guide box 8, a conveying screw 32 arranged in the conveying pipe 31, and a fourth driving motor 33 installed on the material guide box 8 and connected to the conveying screw 32 to drive the conveying screw 32 to rotate. The conveying pipe 31 is inclined and has a mud inlet 7 arranged at one end. The mud inlet 7 can be multiple, and the lower end of the overall conveying pipe 31 is higher than the walking mechanism 5 (i.e., the crawler), so as to prevent the conveying pipe 31 from touching the bottom during movement. The higher end of the conveying pipe 31 is fixedly extended into the material guide box 8. The mud outlet is also located in the material guide box 8. When the fourth drive motor 33 is running, it drives the conveying screw 32, so that the mud enters from the lower mud inlet 7, and then is conveyed to the higher mud outlet to enter the material guide box 8, and then enters the batching box 9 below; further, in order to improve the stability of the overall structure, a reinforcing rod 34 can be added to fix the middle section and / or the lower end of the conveying pipe 31 to the mobile box 4. At the same time, a large number of structural components are arranged in the mobile box 4 and a large amount of materials are stored, so the screw conveyor 6 will not tilt during the process of traveling;

[0031] like Figure 1 As shown, in further detail, the batching box 9 and the mixing box 10 are arranged one high and one low, and the two are connected side by side, which is actually a connected space. The first stirring blade 18 mainly plays a preliminary mixing role in the batching box 9, and the feeding belt 12 plays a role of pulling the material from the batching box 9 to the mixing box 10, and at the same time, the material is downwardly entered into the feeding box 11. In the process, the second stirring blade 20 is arranged to enhance the mixing effect. The material in the feeding box 11 is upwardly returned to the batching box 9 under the action of the first stirring blade 18, the arched channel 29, the return channel 13 and the lifting screw 30 to form a mixing cycle of the material, and finally a shotcrete similar to concrete is formed after multiple cycles of mixing; further, the feeding box 11 is arranged so that part of it exceeds the outside of the mixing box 10 and is lower than the mixing box 10. The pump body of the jet pump 1 can be arranged there, and the operator can also stand there, so as to facilitate the hand-held operation of the injection pipe 2 and the nozzle 3, and facilitate the smooth progress of the construction operation.
