[0002] With the construction and improvement of farmland irrigation facilities, the installation of facilities such as water hydrants has become increasingly important. In farmland, the installation of water hydrants can effectively provide water for crops and promote their growth. After the traditional irrigation pipeline is laid and installed, a wooden formwork is set up at the water hydrant location and fixed, and the concrete is mixed on site and poured directly. This method of mixing concrete on site is likely to pollute farmland soil, and the on-site pouring points are scattered and it is difficult to determine the appropriate mixing points. After installing the water hydrant, the entire formwork cannot be installed, and the two sides need to be assembled in pieces. It is easy to leak during pouring, and the molding quality is poor. At the same time, the concrete of the town pier cannot be backfilled immediately after pouring, and continuous construction is required. The distance between the town piers is far, and the construction is carried out in two times, which affects the construction efficiency.

[0003] For some farmland irrigation pipelines located in mountainous areas, due to the complex terrain and large construction scope, it is difficult for vehicles to reach the designated construction area during the construction process. The transportation of materials and the construction process all rely on manual labor, which is inefficient. A new anchor pier is urgently needed to improve construction efficiency.

[0028] Example 1

[0029] like Figure 1-Figure 7 As shown,

[0030] A template for preparing a prefabricated concrete anchor pier for a farmland irrigation water hydrant, comprising a steel plate side form 1, a steel plate bottom form 2, a pre-buried water hydrant pipe 3 and a pre-buried PVC pipe 4. The number of the steel plate bottom form 2 is one, and the steel plate bottom form 2 is a square steel plate. The number of the steel plate side form 1 is four, and the four steel plate side form 1 are respectively used to connect with the steel plate bottom form 2 to form a complete casting template structure. The four steel plate side forms have the same shape, and the shape of the steel plate side form is rectangular or trapezoidal. The template structure formed by the combination of the steel plate side form and the steel plate bottom form is a rectangular block structure or a four-sided pyramid structure.

[0031] Specifically, in order to realize the connection between the steel plate side form 1 and the steel plate bottom form 2, two bottom form pin holes 5 made of circular steel pipes are welded on the four sides of the steel plate bottom form 2, and two side form pin holes 6 made of circular steel pipes are welded on the bottom of the steel plate side form 1. When the steel plate side form 1 and the steel plate bottom form 2 are combined, the bottom of the steel plate side form 1 and the side of the steel plate bottom form 2 are aligned, so that the side form pin holes 6 and the bottom form pin holes 5 are aligned. After the two pin holes are aligned, they are connected with the pin steel bars 7 to realize the combination of the steel plate side form 1 and the steel plate bottom form 2.

[0032] Two oppositely disposed steel plate side molds 1 are provided with pipe holes 8 for the pre-buried PVC pipes 4 to pass through, each steel plate side mold 1 is provided with two pipe holes 8, and the pipe holes 8 located on the two steel plate side molds 1 are symmetrically arranged with each other.

[0033] Bolt holes 9 for the pre-buried water faucet pipes 3 to pass through are respectively opened on the other two oppositely arranged steel plate side molds 1, and the bolt holes 9 on the two steel plate side molds 1 are symmetrically arranged with each other.

[0034] Specifically, in order to facilitate the installation of the pre-buried water faucet pipe 3, the steel plate side mold 1 is cut by laser cutting. The steel plate side mold 1 is assembled from side mold units 10 made of two steel plates. The two side mold units 10 have the same shape. A semicircular bolt hole 9 is opened on each side mold unit 10. A complete bolt hole 9 is formed by assembling the two side mold units 10.

[0035] Two connecting pins 11 are welded at adjacent positions of the two side mold units 10. The connecting pins 11 are L-shaped. After the two side mold units 10 are assembled, positioning pins 12 are placed on the two side mold units 10. The positioning pins 12 are continuously clamped in the four connecting pins 11 to assemble the two side mold units 10 together.

[0036] In order to ensure that the steel plate side form 1 and the steel plate bottom form 2 remain stable when combined, positioning pin holes 13 are respectively fixed at both ends of the top of each steel plate side form 1, and the positioning pin holes 13 on each steel plate side form 1 are at the same distance from the edge of the steel plate side form 1. When the four steel plate side forms 1 are respectively combined with the steel plate bottom form 2 through the pin holes at the bottom, the four steel plate side forms 1 are in an upright state. At this time, the positioning pin holes 13 on adjacent steel plate side forms 1 are connected together through the positioning bows 14, so that the steel plate side form 1 can be fixed, so that the steel plate side form 1 can remain in an upright state.

[0037] In this embodiment, the pre-buried water faucet pipe 3 is a three-way structure with a T-shaped structure, that is, the pre-buried water faucet pipe 3 includes a crossbar 301 and a vertical pipe 302, and the vertical pipe 302 and the crossbar 301 are interconnected. It will be troublesome to place the pre-buried water faucet pipe 3 in the assembled template combination. Therefore, by setting two oppositely arranged steel plate side molds 1 into two side mold units 10, when installing the pre-buried water faucet pipe 3, after assembling one steel plate side mold 1, first insert one end of the cross pipe of the pre-buried water faucet pipe 3 into the bolt hole 9 of the steel plate side mold 1, and then fix the other steel plate side mold 1 after assembling it, and then translate the crossbar 301 to pass through the bolt hole 9 of the steel plate side mold 1.

[0038] In order to keep the vertical pipe 302 of the pre-buried water faucet pipe 3 in an upright state and to keep the vertical pipe 302 in a centered state, a fixing hook 15 is provided in the middle of each steel plate side form 1. After the pre-buried water faucet pipe 3 is installed in the formwork assembly, the pre-buried water faucet pipe 3 is tied with the iron wire 16. When tying, the vertical pipe 302 is also tied. The front, back, left, right and four directions of the vertical pipe 302 are respectively fixed on the steel plate side form 1 in four directions by the iron wire 16 to keep the vertical pipe 302 upright and centered to avoid displacement during the pouring process.

[0039] The installation of the embedded PVC pipe 4 is relatively simple, and it can be directly passed through the corresponding pipe holes 8 on the two opposite steel plate side molds 1.

[0040] After the pre-buried water hydrant pipe 3 and the pre-buried PVC pipe 4 are installed, concrete can be poured and cured as required. After the precast concrete anchor pier is cured, the positioning pin 12 is pulled out. When removing the mold, the pins on the steel plate bottom mold 2 and the steel plate side mold 1 are pulled out to remove the mold.

[0041] When the strength of the formed anchor pier meets the requirements, the redundant water hydrant pipe and PVC pipe on the side of the steel plate side mold 1 can be cut off. When installing the precast concrete anchor pier, the steel wire rope used for hoisting can be passed through the pre-buried PVC pipe 4 for on-site installation. When installing on-site, the installation site uses an excavator to dig trenches to complete the installation of the anchor pier. After the anchor pier is installed in place, the water supply pipeline laid in advance is connected to the pre-buried water hydrant pipe 3 in the anchor pier by hot-melt welding, and then backfilling can be carried out.

[0042] The template for preparing the prefabricated concrete anchor pier for farmland irrigation water supply hydrant of the utility model is used to solve the problems of inconvenient transportation of materials in farmland with complex terrain, inconvenient concrete mixing and pouring and pollution of farmland, and inability to backfill the trench immediately after pouring the anchor pier, resulting in low construction efficiency. The prefabricated concrete anchor pier of the utility model for farmland irrigation water supply hydrant is manufactured by factory-based unified processing. The template adopts a combined steel template. The steel plate bottom template 2 and the steel plate side template 1 are connected and fixed by a pin type. The water supply pipeline is pre-buried in advance, and the PVC pipe 4 is pre-buried before concrete pouring. During installation, it is hoisted by inserting a steel wire rope.

[0043] The utility model discloses a precast concrete anchor pier which is cast uniformly by means of factory-made steel formwork. The steel plate bottom formwork 2 is a square steel plate. The steel plate side formwork 1 and the steel plate bottom formwork 2 are connected by means of latch holes. A pre-buried water faucet pipe 3 is arranged in the mold formed by the steel plate side formwork 1 and the steel plate bottom formwork 2 for connection with the water supply pipeline. The pre-buried PVC pipe 4 arranged in the mold facilitates lifting during installation.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
