Description

Technical field:

[0001] The invention relates to the technical field of road construction, and in particular to a prefabricated panel for a manure cleaning pit in a cattle shed. Background technology:

[0002] With the favorable livestock breeding policies, local dairy farming has gradually become large-scale and industrialized; dairy farms are an important part of animal husbandry. In the construction of large and medium-sized dairy farms, in accordance with the standardized construction standards of dairy farms, concrete roads need to be laid in dairy farms to ensure the normal life of dairy cows. At the same time, for dairy farm roads, cement concrete is used in the process of paving roads. Compared with other roads, cement concrete pavement has the advantages of being strong and durable, easy to clean manure, easy to wash and disinfect, and good heat dissipation in summer.

[0003] However, due to insufficient quality control of concrete floors during the construction period, unfavorable subsequent maintenance measures, the impact of cows on the ground and long-term wear, organic erosion, uneven foundation settlement, mechanical manure scraping, winter ground icing and other environmental factors, the ground is damaged prematurely within its designed service life, especially the manure pit floor. Within less than 3 years of use, the concrete floor will show sand, potholes, exposed gravel, etc. The probability of this type of deterioration occurring in the manure pit floor is as high as over 95%.

[0004] At the same time, the surface disease of the concrete floor makes the gravel exposed, resulting in the feces and excrement cannot be cleaned up in time, the cattle's hooves are ulcerated, and they are stepped on in feces and urine for a long time, causing feces to be retained between the toes of the cattle's hooves. After the fermentation reaction, many pathogens continue to corrode between the toes, which can easily cause interdigital dermatitis, causing the affected cattle to lame, and causing foot rot and hoof deformation. Summary of the invention:

[0005] In view of this, it is necessary to design a prefabricated panel for cowshed manure cleaning tanks to enhance the ability of dairy farm roads to resist mechanical degradation under complex conditions such as organic erosion, freeze-thaw, and low temperature, reduce the impact of organic matter on steel corrosion in concrete, prevent ground diseases such as potholes and spalling on the concrete surface and steel corrosion, extend the service life of concrete floors, and prevent cow hooves from becoming sick due to external factors such as exposed stones.

[0006] A prefabricated panel for a cowshed manure cleaning pit, comprising: a prefabricated panel body arranged in the cowshed manure cleaning pit in a dairy farm and an anti-skid groove along the direction of the prefabricated panel, wherein the prefabricated panel body comprises, from bottom to top, a base soil layer, a rammed soil layer, a crushed stone cushion layer, a cast-in-place concrete layer and a concrete surface layer.

[0007] Preferably, the anti-slip grooves are arranged along the length direction of the prefabricated panel, with a depth of 10 cm in the length direction, a width of 15 cm at the upper edge, a width of 10 cm at the lower edge, and a spacing of 80 cm.

[0008] Preferably, the anti-skid groove is filled with asphalt sand.

[0009] Preferably, the concrete surface layer is prepared by replacing more than 30% of fine aggregate with Tengger Desert sand.

[0010] Preferably, the concrete surface layer is an assembled desert sand concrete surface layer.

[0011] Preferably, the pre-treatment of the assembled desert sand concrete surface layer is carried out by using one of the following methods: plastic roughening method, grooving method and notching method.

[0012] Preferably, the width of the seams between the assembled desert sand concrete surface panels is 5 mm.

[0013] The prefabricated panel designed by the present invention for the manure cleaning pit of the cowshed is successfully prepared to replace C30-C40 ordinary concrete by replacing more than 30% of fine aggregate with Tengger Desert Sand. By adopting the assembled desert sand concrete pavement, the ability to resist the degradation of mechanical properties under complex conditions such as organic erosion, freeze-thaw, and low temperature is enhanced, the influence of organic matter on the corrosion of steel bars in concrete is reduced, and ground diseases such as potholes and spalling on the concrete surface and steel corrosion are prevented, the service life of the concrete floor is extended, and the cow's hoof is prevented from being sick due to external factors such as exposed stones.

[0021] like Figure 1 As shown in the figure, the structural schematic diagram of the chemically resistant assembled desert sand concrete prefabricated panel for a dairy farm provided by the present invention comprises a prefabricated panel body arranged beside the dairy farm pen 7, and an anti-skid groove along the direction of the prefabricated panel; combined with Figure 3 and Figure 4 As shown, the anti-skid groove is arranged along the length direction of the prefabricated panel and is filled with asphalt sand. It is 10 cm deep in the length direction, 15 cm wide at the upper end, 10 cm wide at the lower end, and 80 cm apart.

[0022] Combination Figure 2 As shown in the figure, the prefabricated panel body is stacked from bottom to top in order of base soil layer 1, rammed soil layer 2, crushed stone cushion layer 3, cast-in-place concrete layer 4, and assembled desert sand concrete surface layer 5; in order to improve the anti-skid property of the assembled desert sand concrete surface layer 5 during processing, its surface needs to be treated, mainly by plastic roughening, grooving and notching. The notching method is the most commonly used method, and the distance between the saw blades can be selected to be different, so that the prefabricated road surface has different anti-skid properties, preventing cows from falling due to slippery ground.

[0023] The chemically resistant prefabricated desert sand concrete panel in this embodiment can use Tengger Desert Sand to replace more than 30% of fine aggregates, and use prefabricated desert sand concrete pavement; the previous cast-in-place concrete pavement was damaged in advance during the design service life due to insufficient quality control of the concrete floor during the construction period, unfavorable later maintenance measures, the impact of cows on the ground and long-term wear, organic erosion, uneven settlement of the foundation, mechanical scraping of manure, winter ground icing and other environmental factors. In particular, the manure cleaning pit floor will have sand, potholes, and exposed stones in the concrete floor within less than 3 years of use. The probability of such deterioration in the manure cleaning pit floor is as high as more than 95%. Using Tengger Desert Sand to replace more than 30% of fine aggregates, a C30-C40 ordinary concrete for foundation, concrete components, pavement, etc. was successfully prepared. This achievement has been carried out on-site engineering testing and project demonstration in the Ningxia dairy farm project. The prefabricated panel body in this embodiment is combined with the existing large-scale farm construction standards. The prefabricated panel body adopts an assembled desert sand concrete pavement to enhance the concrete pavement's resistance to the coupling effects of environmental factors such as organic erosion, uneven foundation settlement, mechanical manure scraping, and winter ground icing, thereby ensuring that the farm prefabricated panels are in good condition and reducing pavement damage caused by chemical erosion.

[0024] In this embodiment, an assembled desert sand concrete pavement is used. By using the assembled desert sand concrete pavement, the ability to resist degradation of mechanical properties under complex conditions such as organic erosion, freeze-thaw, and low temperature is enhanced, the influence of organic matter on steel corrosion in concrete is reduced, and ground diseases such as potholes and spalling on the concrete surface and steel corrosion are prevented. The service life of the concrete floor is extended, and the cow's hooves are prevented from becoming sick due to external factors such as exposed stones.
