Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a channel lining device used in water conservancy projects. Background Art

[0002] As an engineering structure with low engineering cost, convenient construction and large water flow, channels have become the main water transfer method in inter-basin water transfer. However, leakage diseases frequently occur in water transfer channels during operation, especially in cold-region channels, which makes the water utilization coefficient of the channel system less than 0.5, and the annual water loss accounts for nearly 50% of the total agricultural water consumption. The reason is that under the effect of freeze-thaw-dry-wet coupling, the channel foundation soil of the cold-region water transfer channel is frozen and heaved, causing cracks and leakage in the channel lining. After the water seeps down, the water content of the channel foundation soil increases. When the temperature drops, the channel frost heaving damage is aggravated, further causing more serious leakage diseases.

[0003] In the prior art, channel lining is done by a channel lining machine, which moves via a slide rail that needs to be fixed on the ground. However, due to uneven ground flatness, some concrete will be uneven after the channel lining machine is used. At this time, the construction workers need to manually level it. However, the length of the channel lining machine is generally long, and the work intensity is high. Moreover, the existing channel lining machine does not have the function of processing the soil before channel construction. Therefore, when it is applied to water delivery channels in cold regions, it cannot solve the problem of frost heave damage to the channel foundation soil.

The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] like Figures 1 to 4 As shown, the present invention provides a channel lining device for water conservancy projects, including a channel lining machine 1, wherein a spraying mechanism is arranged at the front end of the channel lining machine 1 along the traveling direction, and the spraying mechanism is used to spray a curing agent onto the channel foundation soil; track structures are arranged on both sides of the channel lining machine 1, and an adjusting component is arranged at the bottom of the track structure, and the adjusting component is used to adjust the horizontal height of the track structure; a walking component is fixedly installed on the bottom edge of the channel lining machine 1, and the channel lining machine 1 moves along the track structure through the walking component.

[0026] The present invention sprays a curing agent onto the channel foundation soil through a spraying mechanism, thereby reducing the frost heave deformation of the soil and solving the problem of frost heave damage to the channel foundation soil when the channel lining machine 1 is used in a water delivery channel in a cold region; through the cooperation of a track structure and an adjusting component, the horizontal height of the channel lining machine 1 can be controlled, thereby keeping the channel lining machine 1 stable and avoiding uneven concrete after lining.

[0027] To further optimize the solution, in order to ensure the uniformity of the curing agent sprayed on the channel foundation soil, the spraying mechanism includes a liquid storage tank 2 fixedly installed on the top of the channel lining machine 1, and the front end of the channel lining machine 1 is fixedly connected with a liquid supply pipe 3, the shape of the liquid supply pipe 3 is adapted to the shape of the channel, and a plurality of nozzles 4 are fixedly installed on the liquid supply pipe 3. A water pump is arranged in the liquid storage tank 2, and the water outlet end of the water pump is connected with the water inlet end of the liquid supply pipe 3, and the other end of the liquid supply pipe 3 is a sealed end.

[0028] A further optimization scheme is provided. In order to facilitate the overall movement of the channel lining machine 1 by utilizing the track structure, the track structure includes a sliding track 5. A vertical groove is provided at the bottom end of the sliding track 5. A guide track 6 is installed in the vertical groove for limited sliding. The adjustment component is fixedly installed at the bottom end of the guide track 6; a telescopic cylinder 7 is fixedly connected to the end of the vertical groove away from the spraying mechanism, and the piston end of the telescopic cylinder 7 is in contact with the guide track 6; a plurality of groups of support components are provided at the bottom of the sliding track 5, and the plurality of groups of support components are symmetrically arranged at both ends of the sliding track 5, and the support components are used to support and position the sliding track 5.

[0029] When in use, the sliding rail 5 is supported by the supporting assembly. After the sliding rail 5 is supported stably, the adjusting assembly is controlled to shorten, and then the telescopic cylinder 7 is used to push the guide rail 6 to move. After the guide rail 6 moves to the specified position, the adjusting assembly is restored, and the guide rail 6 is supported again. Then the supporting assembly is restored, and the telescopic cylinder 7 is controlled to restore, so that the channel lining machine 1 can be moved as a whole under the action of the sliding rail 5.

[0030] To further optimize the solution, I use the support assembly to support the sliding rail 5. The support assembly includes two symmetrically arranged L-shaped support plates 8. A mounting hole is opened at the bottom end of the sliding rail 5. The L-shaped support plate 8 is slidably connected in the mounting hole; a telescopic cylinder 2 9 is fixedly connected to the L-shaped support plate 8, and a fixed plate 10 is fixedly connected to the side wall of the sliding rail 5. The top of the telescopic cylinder 2 9 is fixedly connected to the fixed plate 10.

[0031] A further optimized solution is to facilitate the adjustment of the position of the guide rail 6 and ensure the supporting and positioning effect of the adjustment component on the guide rail 6. The adjustment component includes a plurality of telescopic cylinders three 11 fixedly connected to the bottom of the guide rail 6. The distance between two adjacent telescopic cylinders three 11 is the same, and the maximum outer diameter of the telescopic cylinder three 11 is smaller than the distance between the two L-shaped support plates 8 in the same group of support components.

[0032] A further optimized solution is to facilitate the control of the channel lining machine 1 to move along the sliding track 5, and the walking assembly includes a mounting frame 12 fixedly mounted on the edge of the channel lining machine 1, and the end of the mounting frame 12 is rotatably connected to a roller 13, and the roller 13 is arranged in a slide groove at the top of the sliding track 5. A motor 14 is fixedly mounted on the mounting frame 12, and the motor 14 cooperates with the roller 13 in transmission.

[0033] A further optimized solution is to reduce the friction between the guide rail 6 and the sliding rail 5 , a mounting groove is provided at the top of the guide rail 6 , and a plurality of rollers 15 are rotatably connected in the mounting groove, and the guide rail 6 is slidably matched with the sliding rail 5 through the rollers 15 .

[0034] A further optimized solution is to facilitate replacement of the roller 15 when the roller 15 is damaged. A plurality of vertical snap-in grooves are provided on the two groove walls opposite to the installation groove. A snap-in plate 16 is detachably installed in the vertical snap-in groove. The roller 15 is rotatably connected between the two snap-in plates 16.

[0035] A further optimized solution is to prevent the guide rail 6 from falling out of the vertical groove after the adjustment component is shortened. A limiting groove 17 is provided on the side wall of the guide rail 6, and a protrusion is provided on the groove wall of the vertical groove. The guide rail 6 and the sliding rail 5 are limited by the protrusion and the limiting groove 17.

[0036] The solution was further optimized, and the curing agent was anionic polyacrylamide.

[0037] The channel lining device for water conservancy projects provided by the present invention has the following working principles:

[0038] When in use, first adjust the height of the track structure. During the adjustment, control the telescopic cylinder three 11 to extend and retract, use the telescopic cylinder three 11 to adjust the guide track 6 to the horizontal, and cooperate with the level to ensure that the guide track 6 is at the required elevation. At this time, the channel lining machine 1 can be used for lining. When the channel lining machine 1 is lining, the spraying mechanism will first spray anionic polyacrylamide onto the channel foundation soil, and then fill concrete into the channel lining machine 1 to carry out channel lining work. When the channel lining machine 1 needs to move, first, the telescopic cylinder 2 9 is controlled to extend. At this time, the L-shaped support plate 8 slides out of the sliding track 5, and the sliding track 5 is supported by the telescopic cylinder 2 9. After the sliding track 5 is supported stably, the telescopic cylinder 3 11 is controlled to shorten. Then, the telescopic cylinder 1 7 is used to push the guide track 6 to move in the direction of the vertical groove. After the telescopic cylinder 1 7 reaches the maximum stroke, the telescopic cylinder 1 1 is controlled to extend, and the guide track 6 is supported and fixed again. Then, the telescopic cylinder 2 9 is controlled to shorten, and the L-shaped support plate 8 slides back into the sliding track 5. Then, the telescopic cylinder 1 7 is controlled to shorten. Under the action of the telescopic cylinder 1 7, the sliding track 5 moves along the guide track 6. At this time, the channel lining machine 1 moves with the sliding track 5. When the telescopic cylinder 1 7 reaches the minimum stroke, the sliding track 5 stops sliding, and the elevation of the guide track 6 is controlled by the level. Then, the telescopic cylinder 2 9 is controlled to extend, and the sliding track 5 is supported by the telescopic cylinder 2 9 to keep the position of the sliding track 5 stable, thereby completing the position movement of the channel lining machine 1. Then the channel lining machine 1 can be controlled by the traveling assembly to perform the channel lining work again.

[0039] By adding anionic polyacrylamide to loess and conducting a control test with plain loess, the results show that anionic polyacrylamide can destroy the double electrical layer structure of soil particles through charge neutralization, reduce the thickness of the bound water film, and improve the compaction characteristics and water stability of loess due to the hydrophobic effect of its own polymer main chain. At the same time, hydrogen bonds are used to promote the adsorption and aggregation of clay particles to enhance the cementation capacity of loess, the total area and fractal dimension of the soil pores are reduced, the strength of the solidified loess is significantly improved, and the failure stress is the largest when the anionic polyacrylamide dosage is 0.30%, and its cohesion is 1.81 times higher than that of the pure loess sample. Under the action of freeze-thaw cycles, the degradation of its hydrothermal parameters and mechanical properties is reduced, and the degree of damage to the microscopic pore structure of the soil is small. In the unidirectional freezing test, under the action of temperature gradient, water migrates and gathers from the unfrozen area to the freezing front, and condenses into ice, causing the soil volume to expand. The moisture migration of the solidified soil was significantly reduced, which weakened the frost heave deformation of the soil. When the anionic polyacrylamide was added at a ratio of 0.30%, the total frost heave was reduced by 41.65%.

[0040] Therefore, by spraying anionic polyacrylamide, the problem of frost heave damage to the channel foundation soil when the channel lining machine 1 is applied to the water delivery channel in cold regions is solved.

[0041] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
