[0001] The utility model relates to the technical field of slope stability, in particular to a slope form for high fill slope of transformer substation. BACKGROUND
[0002] When the station area fill slope is high, the conventional reinforced slope scheme is to use geogrid reverse package planting base bag for reinforcement, but the slope planting base bag needs manual bagging and laying, which takes a long time, seriously affects the construction progress, and seriously affects the construction progress for the project with tight construction period. UTILITY MODEL CONTENT
[0003] The utility model aims at providing a slope form for high fill slope of transformer substation to solve the problems of high labor cost, time-consuming and laborious, slow construction progress and low work efficiency in the prior art.
[0004] The embodiment of the utility model is realized as follows:
[0005] The utility model embodiment provides a slope form for high fill slope of transformer substation, which comprises a backfill body;
[0006] One end of the backfill body is provided with a slope surface, the slope surface and the backfill body are integrally formed, the backfill body has a plurality of backfill layers inside, geogrids are clamped between adjacent backfill layers, one end of the geogrid close to the slope surface is provided with spun cloth, and the spun cloth has backfill soil inside.
[0007] When the backfill body is backfilled, the backfill body is separated into a plurality of layers by the geogrid, one end of the geogrid close to the slope surface is wrapped with the spun cloth, and the backfill soil is wrapped inside the spun cloth, so that the backfill body close to the slope surface is more stable through the top pressure.
[0008] The slope form for high fill slope of transformer substation disclosed in the embodiment is more stable inside due to the use of the layer-by-layer arranged geogrid, the spun cloth can prevent soil loss and filter water at the same time, the structure of the backfill body is more stable and not prone to landslides, and the slope form for high fill slope of transformer substation has the beneficial effects of low labor cost, time and labor saving, fast construction progress and high work efficiency.
[0009] Optionally, the geogrid has a first layer of geogrid, a second layer of geogrid and a third layer of geogrid, the first layer of geogrid, the second layer of geogrid and the third layer of geogrid are parallel and spaced apart, the first layer of geogrid, the second layer of geogrid and the third layer of geogrid have a folding section folded upward at one end close to the slope surface, the folding section of the first layer of geogrid is connected to the second layer of geogrid, and the folding section of the second layer of geogrid is connected to the third layer of geogrid.
[0010] In this way, by arranging the first layer of geogrid, the second layer of geogrid and the third layer of geogrid inside the backfill body, the overall structural strength and stability of the backfill body can be enhanced, and landslides can be avoided. The arrangement of the folding section enables the first layer of geogrid, the second layer of geogrid and the third layer of geogrid to be connected at one end close to the slope surface to form a whole, thereby fixing the backfill soil. Meanwhile, the folding section is folded upward and is compressed by the upper backfill soil, effectively preventing displacement of the first layer of geogrid, the second layer of geogrid and the third layer of geogrid.
[0011] Optionally, a first connecting rod is arranged between the folding section of the first layer of geogrid and the second layer of geogrid, and the folding section of the first layer of geogrid is fixedly connected to the second layer of geogrid by the first connecting rod.

[0015] The bottom layer of geotextile, the middle layer of geotextile and the top layer of geotextile are folded upward at one end close to the slope surface to form a trapezoidal cavity, and the backfill soil is embedded in the trapezoidal cavity.
[0016] In this way, the bottom layer of geotextile, the middle layer of geotextile and the top layer of geotextile wrap the backfill soil through the trapezoidal cavity, achieving the effect of surface soil fixation. Under the action of the upper pressure, the bottom layer of geotextile, the middle layer of geotextile and the top layer of geotextile are compressed more tightly, so that the backfill soil close to the slope surface forms a block, which is not easy to loosen, effectively avoiding landslides and being conducive to reinforcing the slope surface.
[0017] Optionally, the bottom layer of spun fabric, the middle layer of spun fabric and the top layer of spun fabric are connected end to end at the end away from the slope.
[0018] In this way, the bottom layer of spun fabric, the middle layer of spun fabric and the top layer of spun fabric are pressed by the weight of the upper backfill soil, so that the end of the bottom layer of spun fabric, the middle layer of spun fabric and the top layer of spun fabric close to the slope is not easy to loosen, ensuring the integrity, and facilitating the realization of the slope surface soil fixation.
[0019] Optionally, the slope is provided with spray seeding greening.

[0021] Optionally, the end of the bottom layer of spun fabric, the middle layer of spun fabric and the top layer of spun fabric away from the slope is connected end to end with a length of 1000mm.
[0022] In this way, the bottom layer of spun fabric, the middle layer of spun fabric and the top layer of spun fabric can be prevented from being scattered after being folded.
[0023] Optionally, the distance between the adjacent first layer of grids, the second layer of grids and the third layer of grids is 500mm.
[0024] In this way, the tightness of the backfill body can be ensured, and the stability of the overall structure of the backfill body is ensured, and landslide is avoided.
[0025] Optionally, the top surface of the backfill body is provided with a prefabricated concrete coping, and the prefabricated concrete coping is located at the connection between the top surface of the backfill body and the slope.
[0026] In this way, the prefabricated concrete coping can provide uniform pressure, so that the third layer of grids, the top layer of spun fabric, the second layer of grids, the middle layer of spun fabric, the first layer of grids and the bottom layer of spun fabric are sequentially stressed and extruded, and the purpose of soil fixation is achieved.
