Problems solved by technology
[0003] The first purpose of the present invention is to provide a method for producing concrete prefabricated parts that can improve the quality of the prefabricated parts everywhere and enable reliable bonding between the prefabricated parts and the decorative stucco layer, which solves the existing problems The quality consistency of the concrete prefabricated parts produced by the method is poor and the problem of easy peeling between the same stucco layer
[0004] The second purpose of the present invention is to further provide a trailer for the production method of concrete prefabricated parts, in which the distance between each wheel and the center of the vehicle body can be adjusted independently, which solves the problem that the existing concrete production trailers cannot adapt to different roads. wide question

Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0030] A method for producing a concrete prefabricated part. The first step is to make a concrete prefabricated part; the second step is to place the concrete prefabricated part suspended in the air, and regularly pour lime water from the opposite sides of the concrete prefabricated part for maintenance. Carbon dioxide is blown toward the surface of the concrete prefabricated blank while the lime water is applied so that the lime water forms a calcium carbonate layer bonded to the surface of the concrete prefabricated blank. Specifically, the second step is completed in the spray booth, and the concrete precast blank is transferred to the spray booth by a trailer.
[0031] see figure 1 , The spray shed includes a shed body 31 , a water delivery pump 32 , an air delivery pump 33 and a lime water storage tank 34 . The shed is provided with a pr...

The invention discloses a method for producing a concrete prefabricated part. The first step is to make a concrete prefabricated part blank; the second step is to place the concrete prefabricated part blank in the air, and regularly pour lime water from opposite sides of the concrete prefabricated part blank For curing, while pouring lime water, carbon dioxide is blown toward the surface of the concrete prefabricated blank so that the lime water forms a calcium titanate layer bonded to the surface of the concrete prefabricated blank. The first purpose of the present invention is to provide a method for producing concrete prefabricated parts that can improve the quality of the prefabricated parts and enable reliable bonding between the prefabricated parts and the decorative stucco layer, which solves the existing problems The quality consistency of the concrete prefabricated parts produced by the method is poor everywhere, and the phenomenon of peeling off between the same stucco layer is easy to occur.
Description
technical field [0001] The invention relates to the technical field of concrete prefabricated parts production, in particular to a method for producing concrete prefabricated parts. Background technique [0002] In the construction process of road bridge tunnels, concrete prefabricated parts are often produced and assembled on site to form bridge culverts, etc. During the production and transportation of precast concrete parts, trailers are used to transport materials and products. The trailer is composed of a frame, a load carrier (bucket or bracket) arranged on the frame, and walking wheels supporting the frame. Due to changes in the use environment, it is often necessary to use trailers with different wheelbases for transportation on roads of different widths, resulting in many types of vehicles. What is more unfavorable is that when the same batch of goods passes through roads with different road widths Transshipment is required, resulting in decreased production effic...
