Description

Technical Field

[0001] The utility model relates to a prefabricated manure ditch wallboard and a manure ditch constructed by the prefabricated manure ditch wallboard, and belongs to the technical field of farm construction. Background Art

[0002] At present, pig houses in farms usually need to build manure ditches. The manure ditches are generally located below the ground of the pig houses. A slatted floor is installed on top of the manure ditches. The feces produced by the live pigs and the sewage produced by flushing the pig feces and urine enter the manure ditch below through the strip holes of the slatted floor.

[0003] Traditional pig house manure ditches are made of on-site cast reinforced concrete structures. The construction of such manure ditches requires the process of formwork, pouring, and maintenance. The on-site workload is large, the construction period is long, and the construction cost is high. In addition, the construction quality of on-site cast manure ditches is difficult to control, and they are prone to cracking and poor durability, resulting in a short service life of such manure ditches. In addition, current farms are usually large-scale and standardized farming, and the errors between the components of on-site cast manure ditches are large, which makes it difficult to meet the use needs of large-scale and standardized farm pig houses.

[0004] Chinese patent CN202021322208.2 discloses an assembled prestressed concrete prefabricated pig house manure ditch. Compared with the traditional cast-in-place manure ditch, the prefabricated manure ditch in this patent is convenient for on-site construction and has a short construction period, but its structure is relatively complex. In addition to various prefabricated manure ditch side panels and prefabricated manure ditch bottom plates, it also includes reinforced concrete supporting columns, reinforced concrete full-length beams, prefabricated concrete structural beams, etc., and the assembly is relatively complex and the production cost is relatively high.
