The vertical section 502 of the T-shaped hard support 5 is positioned at the side of the terrace pit and is buried and compacted by excavation soil to be used as a terrace ridge 3. Geotextile 6 is paved above the crushed stone mud layer 4 and then is filled with planting matrixes, so that a terraced field planting pit 2 is formed. As shown in fig. 3, a drainage canal 10 is arranged at one side of the terrace pit from top to bottom along the sloping field 1, and an adjusting drainage device 7 is arranged between the terrace planting pit 2 and the drainage canal 10.
The drainage device 7 includes: a movable baffle 701 and a fixed baffle 702, wherein the movable baffle 701 is controlled by a lifting device to perform lifting movement relative to the fixed baffle 702. The accumulated water in the terrace planting pit 2 flows out from the top of the movable baffle 701 to the drainage canal 10.
The lifting device is in signal connection with the control end, and after the control end performs drainage control analysis, the control end sends a control instruction to the lifting device to control the movable baffle 701 to perform lifting movement.
As shown in fig. 4, the lifting device includes: and upright posts 703 fixed to both sides of the fixed baffle 702. A stud 704 is arranged in the upright post 703 along the vertical direction, the top end of the stud 704 is rotatably connected with the top side wall of the upright post 703 through a first bearing 706 and extends to the outside of the upright post 703, and the bottom end of the stud 704 is rotatably connected with the bottom side wall of the upright post 703 through a second bearing 705. The stud 704 is in threaded connection with a shaft sleeve 708, and the shaft sleeve 708 is fixed with the movable baffle 701 through the fixed frame 8. The stud 704 is provided with a stop plate 707 between the sleeve 708 and the first bearing 706, the stud 704 being rotatably connected to the stop plate 707 by a third bearing.
The terraced fields are arranged on hillsides, and are common in land reclamation work. The conventional sloping field terrace generally adopts a mode shown in fig. 1, wherein a planting pit 2 is excavated on a sloping field 1, and excavated soil is piled up on the downhill slope of the planting pit to form a ridge 3. However, in the prior art, the formation of the ridge mainly depends on the piling of the excavated mountain soil, so that on one hand, the water fixing capability is poor, and the rainwater cannot be effectively and safely left in the terraced fields. On the other hand, collapse is easy to occur when the rain is washed out in rainy season, and the rain is a potential safety hazard.
The application adopts a special structural design, and specifically comprises the following steps: the horizontal section 501 of the T-shaped hard support 5 is buried by adopting a crushed stone mud layer 4 at the bottom of the terrace pit. The vertical section 502 of the T-shaped hard support 5 is positioned at the side of the terrace pit and is buried and compacted by excavation soil to be used as a terrace ridge 3. Geotextile 6 is paved above the crushed stone mud layer 4 and then is filled with planting matrixes, so that a terraced field planting pit 2 is formed. A drainage channel 10 is arranged at one side of the terrace pit from top to bottom along the sloping field 1, and an adjusting drainage device 7 is arranged between the terrace planting pit 2 and the drainage channel 10. When in a rainy season, rainwater accumulates in the planting pit 2 and permeates through the planting substrate to the lower layer. The planting substrate completes the first water fixation and water retention. When the water permeates to the bottom layer of the planting substrate, the geotextile 6 can limit the water to permeate to a limited extent, so that on one hand, the water fixation and water retention are realized, and on the other hand, the excessive water accumulated in the planting pit 2 is discharged to the crushed stone soil layer 4. The broken stone mud layer 4 can keep the basic mechanism of the planting pit 2 from deforming while storing water, so that the soil layer structure is prevented from loosening and softening due to excessive water storage. Meanwhile, the T-shaped hard support 5 plays a role in supporting the planting pit 2 in an auxiliary manner and maintaining the basic structural strength of the terrace ridge 3. Therefore, the water fixing device for the terraced fields in the hillside fields has good water fixing and retaining capacity, is safe and reliable, and is not easy to cause safety accidents.
In addition, the drainage device comprises a lifting device, and the stud 704 can be rotated according to the requirement, so that the shaft sleeve 708 is driven to move up and down relatively on the stud 704, and the movable baffle 701 is driven to move up and down relatively to the fixed baffle 702 through the fixed frame 8, so that the height of the planting pit relative to the drainage canal is automatically adjusted, and the working state of water fixation and drainage is switched when necessary.
Example 2
Based on the soil improvement slope terrace water fixing device of the embodiment 1, as shown in fig. 4, when the movable baffle 701 is located at the bottommost position, the shaft sleeve 708 is located at the initial position. The distance between the limiting plate 707 and the initial position of the sleeve 708 is less than or equal to the height of the retaining plate 702. This arrangement may prevent the flapper 701 from moving to a position away from the fixed flapper 702 by the added stop plate 707, resulting in structural failure.
Example 3
Based on the land reclamation slope terrace water fixing device of the embodiment 1, as shown in fig. 4, a gear 709 is arranged between the initial position of the shaft sleeve 708 and the second bearing 705 of the stud 704, and the gears 709 of the two studs 704 are driven by a chain 710. By adding the mechanism, the two sides of the movable baffle 701 can synchronously move, so that the phenomenon that the movable baffle 701 is extruded sideways in the moving process due to the difference of the movement of the two sides is avoided, and the studs 704 on the two sides are damaged.
Example 4
Based on the water fixing device for the terrace of the land reclamation sloping field in the embodiment 1, as shown in fig. 5, the fixing frame 8 is hinged with the movable baffle 701 through a rotation shaft 801. The movable baffle 701 is located below the rotating shaft 801, one side facing the fixed baffle 702 is sequentially provided with at least 2 rollers 7011 from top to bottom, and the diameters of the rollers 7011 arranged in sequence are sequentially reduced from top to bottom. The bottom end surface of the movable baffle 701 is an arc surface.
The fixed baffle 702 faces one side of the movable baffle 701, a sliding groove 7021 is formed in a position corresponding to the roller 7011, and the bottom end surface of the sliding groove 7021 is an arc surface matched with the bottom end surface of the movable baffle 701.
When it is desired to provide a flapper 701 that slides relative to a fixed flapper 702, the prior art typically uses a plurality of rollers 7011 that are positioned flush for sliding. However, gaps are generally formed in the sliding process of the roller 7011, so that the accumulated water in the planting pit 2 easily leaks out of the gaps, and the movable baffle 701 cannot perform a good water blocking function. If a dynamic sealing structure is adopted, the structure is complex, and the water in the planting pit 2 is generally muddy water, the dynamic sealing is easy to cause the problems of abrasion, mechanism operation inhibition and the like caused by the sand and the sediment sinking into the mechanism in such an environment.
In order to solve the above problems of the prior art, the present application employs a plurality of rollers 7011 which are obliquely arranged to slide. At this time, because the movable baffle 701 is obliquely arranged relative to the fixed baffle 702, when the movable baffle 701 moves upwards, the bottom end surface of the movable baffle 701 is obliquely propped in the chute 7021, and under the dual functions of the gravity of the movable baffle 701 and the water pressure of the accumulated water in the planting pit 2, the bottom end surface of the movable baffle 701 is tightly contacted with the chute 7021, so that the accumulated water in the planting pit 2 is effectively prevented from leaking from the contact surface of the movable baffle 701 and the chute 7021. When the movable baffle 701 moves downwards, the bottom end surface of the movable baffle 701 scrapes the sliding groove 7021, so that the sediment accumulated in the sliding groove 7021 is scraped away, and the damage of the sediment accumulated in the sliding groove 7021 to the device is avoided.
Example 5
Based on the water fixing device for the terrace of the land reclamation sloping field of the embodiment 4, as shown in fig. 5, the sliding groove 7021 is detachably and fixedly provided with a polytetrafluoroethylene sliding belt 7023 along the shape of the groove surface. The polytetrafluoroethylene sliding belt 7023 is additionally arranged, so that friction force between the movable baffle 701 and the sliding groove 7021 in the moving process can be reduced, and the abrasion rate of the bottom end surface of the movable baffle 701 can be effectively relieved.
Example 6
Based on the water fixing device for a terrace of a land reclamation sloping field according to the embodiment 4, as shown in fig. 6, a roller 7012 of the roller 7011 is rotatably connected with a fourth bearing 7013, and a side of the fourth bearing 7013 facing the movable baffle 701 is slidably connected with a roller chute 7016 formed by the movable baffle 701 through a fixed column 7014. The roller chute 7016 is an inverted T-shaped platform, the width of the T-shaped platform below the roller chute 7016 is matched with the width of the fourth bearing 7013, and the height is 2/3-3/4 of the height of the fixed column 7014. The fixed column 7014 is connected with the roller chute 7016 through a spring 7015.
With this arrangement, the roller 7011 can adaptively adjust the relative position of the roller 7011 and the flapper 701 according to the change of the position of the flapper 701 during movement. For example: when the flapper 701 moves upward, the roller 7011 near the rotation shaft 801 is pushed by the spring 7015 to move outward of the roller chute 7016 to maintain rolling contact with the chute 7021. The roller 7011 far away from the rotating shaft 801 is pressed and moves towards the inside of the roller chute 7016, and is tightly pressed against the chute 7021 under the pushing of the spring 7015, so that a better sealing effect is realized. In this case, the drain device 7 of the present application cannot completely avoid the problem of water leakage, but can maintain the basic water retention function, thereby realizing the design function required in the present application.
