Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural technology, in particular to a high-standard farmland water conservancy irrigation system building structure and method. BACKGROUND

[0002] High-standard farmland is a modern good farmland that is built by the state to ensure food security and improve agricultural production capacity. It is not only arable land, but also high-quality arable land with comprehensive ability of "rain and flood protection, stable and high yield" after systematic planning and engineering construction. High-standard farmland is a high-level form and construction goal of arable land and permanent basic farmland. Its requirements are to achieve the requirements of flat field, concentrated and contiguous, perfect facilities, water-saving and high efficiency, supporting of agricultural electricity, machine operation, fertile soil, ecological friendly, strong disaster resistance, etc.

[0003] The construction of high-standard farmland mainly focuses on the comprehensive management of "field, soil, water, road, forest, electricity, technology, and management" and other aspects. At present, China has cumulatively built more than 1 billion mu of high-standard farmland, and has set a clear goal to cumulatively build 13.5 billion mu of high-standard farmland by 2030, and to build all the permanent basic farmland with conditions into high-standard farmland by 2035.

[0004] The upgrading of high-standard farmland from existing farmland mainly focuses on the basic situation of existing farmland combined with the above eight aspects. China has a vast territory, and the topographic features of different regions are different. For example, in the southwest mountainous area, emphasis should be placed on building terraces and roads, and in the plain area, emphasis should be placed on perfecting the tank drainage system.

[0005] During our investigation in the villages and towns under the jurisdiction of Huangchuan County in Xinyang City, Henan Province, we found that part of the surface in this area is relatively open, the water source is perfect, and it meets the standard for building high-standard farmland. However, the problem in many areas is the traffic problem, especially in rural areas, there is a problem of generally narrow roads. This is because the residential land of farmers is relatively scattered, and the width of the road is not designed to be too wide at the beginning of road construction in consideration of cost. Over time, the farmland gradually approaches the road, compressing the expandable area on both sides of the road, and the channels on both sides of the road increase the difficulty of subsequent road expansion. According to the actual survey data, the width of the main road between some farmlands is less than three meters, and the intersection of oncoming vehicles is already difficult, let alone the passage of large agricultural machinery, which restricts the construction of high-standard farmland. The expansion of the road needs to occupy the space of the channels on both sides, in addition, the roadbed is higher than the horizontal plane of the farmland on both sides, and the expansion of the road also needs to be filled on both sides, the whole process is relatively troublesome.

[0006] Furthermore, when expanding on both sides of the original road, the expanded sections inevitably experience downward tilting and settlement at their outer edges during actual use. Summary of the Invention

[0007] This invention relates to a high-standard farmland irrigation system construction structure and method. It provides a design concept for upgrading roads and irrigation systems in farmland with narrow existing roads and drinking water channels on both sides of the roads, upgrading the roads and channels without damaging the original roads or changing the channels.

[0008] The present invention adopts the following technical solution: A high-standard farmland irrigation system includes a structure comprising pile foundations laid in channels on both sides of a road and a concrete layer laid on the inner wall of the channel. The concrete layer is integrated with the pile foundations, and a crossbeam spanning the channel is provided on top of the pile foundations. A pavement layer is poured above the crossbeam. The pavement layer is flush with the upper surface of the road. When the horizontal height of the pavement layer is equal to the height of the concrete layer in the channel, the width of the pavement layer covers half of the channel. When the horizontal height of the pavement layer is higher than the total height of the concrete layer in the channel, the pavement layer covers part or all of the channel.

[0009] The pile foundation comprises multiple evenly distributed groups, with each group consisting of two piles on the same vertical plane. One pile is located at the edge of the road, and the other is located inside the channel. The concrete layer is laid along the inner surface of the channel, with the side closest to the road supporting the top surface of the pile closest to the road. The other pile passes through the concrete layer, and each group of piles has a crossbeam at the top. The pile foundation, concrete layer, and crossbeam are all constructed by casting.

[0010] Furthermore, the concrete layer is designed as an inverted right-angled trapezoid, with its inclined side close to the road and the side away from the road being vertical. The pile foundation away from the road and the vertical concrete layer are an integral structure. The top of the pile foundation is flush with or higher than the top of the concrete layer.

[0011] Furthermore, the bottom of the concrete layer is provided with inclined support piles, one end of which is connected to the bottom of the pile foundation adjacent to the road, and the other end is supported to the bottom of the concrete layer; and the thickness of the concrete layer corresponding to the bottom of the channel is greater than the thickness of the other two sides.

[0012] A method for constructing a high-standard farmland irrigation system includes the following steps: pile foundation drilling, pile foundation pouring, concrete layer pouring, crossbeam pouring, and pavement layer pouring.

[0013] Its specific steps include: 1) Drilling holes for pile foundations: Piling holes were drilled near the road and along the outer edge of the channel. The depth of the pile holes near the channel was twice the distance from the road surface to the bottom of the channel; the depth of the pile holes along the outer edge of the channel was lower than the bottom of the channel. 2) Pile foundation pouring: Concrete is poured at the two pile holes. The upper surface of the pile foundation near the road is reserved to allow space for the pouring of the crossbeam from the bottom of the road, and the top surfaces of the two pile foundations are kept flush. 3) Casting of inclined pile foundations: Drilling and pouring concrete at an inclined angle at the bottom of the channel between the two piles. 4) Road cleaning: The bottom of the channel is cleaned, the channel near the road is sloping, the bottom of the channel is flat, and the outer side of the channel is vertical. 5) Concrete layer pouring: Concrete was poured into the repaired channel. The concrete layer at the bottom of the channel was relatively thick, while the concrete layers on both sides were relatively thin. The top of the sloping concrete layer corresponded to the inner pile foundation, and the vertical concrete layer was poured as a single unit with the outer pile foundation. 6) Casting of crossbeams: Cast the crossbeam between the tops of the two crossbeams; 7) Road surface layer pouring: A steel cage is assumed between adjacent beams and concrete is poured to form a pavement layer, with the upper surface of the pavement layer flush with the road.

[0014] The present invention, by adopting the above technical solution, has the following beneficial effects: In this scheme, for the expansion operation of narrow roads, the road surface layer is directly assumed to be above the channel. Multiple sets of pile foundations can ensure the stability of the road surface layer. The road surface layer covering or partially covering the channel will not affect the water intake operation in the channel. On the other hand, it can also cover the channel to a certain extent, which can reduce evaporation. Attached Figure Description

[0018] The present invention will be further described below with reference to the embodiments. It should be understood that the following embodiments are only one or more manifestations of the present invention and are not a complete limitation on the invention content recorded in this application.

[0020] A high-standard farmland irrigation system includes a structure comprising pile foundations laid in channels on both sides of a road and a concrete layer laid on the inner wall of the channel. The concrete layer is integrated with the pile foundations, and a crossbeam spanning the channel is provided on top of the pile foundations. A pavement layer is poured above the crossbeam. The pavement layer is flush with the upper surface of the road. When the horizontal height of the pavement layer is equal to the height of the concrete layer in the channel, the width of the pavement layer covers half of the channel. When the horizontal height of the pavement layer is higher than the total height of the concrete layer in the channel, the pavement layer covers part or all of the channel.

[0021] The pile foundation comprises multiple evenly distributed groups, with each group consisting of two piles on the same vertical plane. One pile is located at the edge of the road, and the other is located inside the channel. The concrete layer is laid along the inner surface of the channel, with the side closest to the road supporting the top surface of the pile closest to the road. The other pile passes through the concrete layer, and each group of piles has a crossbeam at the top. The pile foundation, concrete layer, and crossbeam are all constructed by casting.

[0022] Furthermore, the concrete layer is designed as an inverted right-angled trapezoid, with its inclined side close to the road and the side away from the road being vertical. The pile foundation away from the road and the vertical concrete layer are an integral structure. The top of the pile foundation is flush with or higher than the top of the concrete layer.

[0023] Furthermore, the bottom of the concrete layer is provided with inclined support piles, one end of which is connected to the bottom of the pile foundation adjacent to the road, and the other end is supported to the bottom of the concrete layer; and the thickness of the concrete layer corresponding to the bottom of the channel is greater than the thickness of the other two sides.

[0024] A method for constructing a high-standard farmland irrigation system includes the following steps: pile foundation drilling, pile foundation pouring, concrete layer pouring, crossbeam pouring, and pavement layer pouring.

[0025] Its specific steps include: 1) Drilling holes for pile foundations: Piling holes were drilled near the road and along the outer edge of the channel. The depth of the pile holes near the channel was twice the distance from the road surface to the bottom of the channel; the depth of the pile holes along the outer edge of the channel was lower than the bottom of the channel. 2) Pile foundation pouring: Concrete is poured at the two pile holes. The upper surface of the pile foundation near the road is reserved to allow space for the pouring of the crossbeam from the bottom of the road, and the top surfaces of the two pile foundations are kept flush. 3) Casting of inclined pile foundations: Drilling and pouring concrete at an inclined angle at the bottom of the channel between the two piles. 4) Road cleaning: The bottom of the channel is cleaned, the channel near the road is sloping, the bottom of the channel is flat, and the outer side of the channel is vertical. 5) Concrete layer pouring: Concrete was poured into the repaired channel. The concrete layer at the bottom of the channel was relatively thick, while the concrete layers on both sides were relatively thin. The top of the sloping concrete layer corresponded to the inner pile foundation, and the vertical concrete layer was poured as a single unit with the outer pile foundation. 6) Casting of crossbeams: Cast the crossbeam between the tops of the two crossbeams; 7) Road surface layer pouring: A steel cage is assumed between adjacent beams and concrete is poured to form a pavement layer, with the upper surface of the pavement layer flush with the road.

[0026] like Figure 1 The image shows the current state of existing rural roads, which are generally narrow with water channels on both sides.

[0027] like Figure 1 and Figure 2 The two system architectures shown are as follows: Figure 1 The roads and canals are generally flat, and at this time the road surface layer can occupy part of the canal, leaving part of the canal exposed to facilitate water intake operations. Figure 2 The overall height of the road is higher than the upper surface of the channel. In this case, the height of the outer pile foundation can be increased, and the road surface layer can partially or completely cover the surface of the channel. The raising of the outer pile foundation can leave a space for water intake between the outer facade of the channel and the road surface layer. In this case, even if the road surface layer completely covers the top of the channel, it will not affect the water intake operation.

[0028] The structure of pile foundation combined with concrete layer can provide a certain degree of support to the soil in actual use, and the phenomenon of pavement layer settlement will not occur in actual use.
