Abstract
Description
Technical Field
[0001] This utility model relates to an ecological production channel in hilly areas. It is applicable to the field of ecological agricultural engineering. Background Technology
[0002] Due to its undulating terrain, hilly areas are mostly covered by terraced fields. Terraced fields are strip-shaped steps or wave-shaped sections built along contour lines on hillsides. They are an effective measure to control soil erosion on sloping farmland, and have significant effects on water storage, soil conservation, and increased production.
[0003] Currently, the ridges in terraced fields, which serve as ecological corridors, are classified into earthen ridges, stone ridges, and plant-covered ridges, depending on the materials used. Earthen ridges are the most common. These ridges present the following prominent problems: The ridges are located at the edges of each level of terrace. Water in the terraces often overflows from the upper level through the overflow outlets on its ridges to the lower level. Due to the difference in elevation between the upper and lower levels, the overflowing water from the upper level continuously erodes the outer surface of the ridge, which can easily cause soil erosion when large volumes of water are involved, and in severe cases, can lead to the collapse of the ridge. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide an ecological production channel in hilly areas, addressing the aforementioned problems.
[0005] The technical solution adopted by this utility model is: an ecological production channel in hilly areas, comprising:
[0006] Main body of the earthen embankment;
[0007] A geotextile bag, comprising several geotextile bags filled with soil, is embedded in an overflow outlet that extends from the outer side of the earthen embankment body and stacks from the bottom of the outer side of the earthen embankment body to the top of the earthen embankment body.
[0008] The outer side of the geotextile bag is concave in the middle to form a groove, and the grooves in the middle of the outer side of the upper and lower geotextile bags cooperate to form a flow channel corresponding to the overflow port.
[0009] A first bamboo pole is provided on the inner side of the geotextile bag. The two ends of the first bamboo pole are fixed to the geotextile bag, and the middle part of the first bamboo pole is tied to the middle part of the geotextile bag by a binding strap, thereby forming the groove in the middle of the outer side of the geotextile bag.
[0010] A second bamboo pole is inserted into the gap between the geotextile bag and the first bamboo pole, and the second bamboo pole is driven into the soil of the main body of the earthen embankment.
[0011] The angle α between the second bamboo pole and the horizontal plane is 45 degrees to 90 degrees.
[0012] A bamboo raft was laid underneath the geotextile bag.
[0013] The beneficial effects of this utility model are: by stacking geotextile bags on the outer side of the earthen embankment, the grooves on the outer side of the geotextile bags form a flow channel. The water overflowing from the overflow port at the top of the earthen embankment enters the next level of terrace through the flow channel, avoiding erosion of the earthen embankment and minimizing soil loss.

[0017] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0018] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0019] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0020] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.
[0021] This embodiment is an ecological production channel in hilly areas. The production channel includes earthen embankments at the edges of terraced fields at each level. The upper end of the earthen embankment has an overflow outlet, through which water from the upper terrace can overflow to the lower terrace.
[0022] In this example, a geotextile bag pile is provided on the outer side of the earthen embankment body. The geotextile bag pile corresponds to the overflow outlet at the upper end of the earthen embankment body. The geotextile bag pile is formed by stacking several geotextile bags filled with soil one on top of the other, and the geotextile bag pile is adapted to the slope of the outer side of the earthen embankment body.
[0023] In this embodiment, the outer side of the geotextile bag is concave in the middle to form a groove. The grooves in the middle of the outer side of each geotextile bag inside the geotextile bag pile cooperate to form a flow channel corresponding to the overflow port.
[0024] In this embodiment, the water overflowing from the overflow outlet at the top of the earthen embankment flows into the next level of terraced fields through the flow channel on the geotextile bag pile. The water flows onto the geotextile and does not directly wash away the soil, thus minimizing soil loss.
[0025] In some specific embodiments, a first bamboo pole is provided on the inner side of the geotextile bag. The length of the first bamboo pole is basically the same as the inner side of the geotextile bag. The two ends of the first bamboo pole are fixed to the two ends of the inner side of the geotextile bag by fixing straps. The middle part of the first bamboo pole is tied and fixed to the middle part of the geotextile bag by binding straps. The binding straps tightly bind the first bamboo pole and the geotextile bag, so that the binding straps and the first bamboo poles form the groove in the middle of the outer side of the geotextile bag.
[0026] In this embodiment, a stable groove is formed in the middle of the outer side of the geotextile bag by using a low-cost first bamboo pole and binding strap. The groove structure is stable and not easily affected by external factors.
[0027] In some more specific embodiments, a second bamboo pole is inserted into the gap between the geotextile bag and the first bamboo pole, and between the binding strap and the fixing strap. The second bamboo pole is driven into the soil of the earthen embankment body. The angle α between the second bamboo pole and the horizontal plane is 45 degrees to 90 degrees, so as to fix the geotextile bag to the earthen embankment body through the second bamboo pole.
[0028] In this embodiment, a second bamboo pole is inserted into the gap between the geotextile bag and the first bamboo pole, so as to fix the geotextile bag by using the second bamboo pole driven into the soil, thereby stabilizing the geotextile bag stack structure.
[0029] In some specific embodiments, a bamboo raft of the same size as the geotextile bag is laid under the geotextile bag to provide a stable foundation for the geotextile bag and improve the overall structural stability of the geotextile bag stack.
[0030] The construction method for the ecological production channel in the hilly area in this embodiment includes:
[0031] Excavate to the bottom of the main foundation of the earthen embankment, and lay the first layer of bamboo rafts at the predetermined position on the bottom of the foundation;
[0032] Place the first layer of geotextile bags on the first layer of bamboo rafts, with the geotextile bags facing outwards;
[0033] Insert a second bamboo pole into the gap between the first geotextile bag and the first bamboo pole, and drive the second bamboo pole into the soil until the upper end of the second bamboo pole does not exceed the top surface of the geotextile bag. Backfill the soil to the top surface of the geotextile bag and compact it.
[0034] The same method was used to construct each layer of bamboo rafts, geotextile bags, and second bamboo poles until the top of the main earthen embankment was approached.
[0035] Backfill the soil up to the top of the main earthen embankment.
[0036] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
