Preparation method of prefabricated foam fiber self-repairing concrete public pipeline cover plate

Abstract

The invention provides a preparation method of a prefabricated foam fiber self-repairing concrete public pipeline cover plate. The preparation method comprises the following steps that 10) a steel formwork is prepared according to the preset size; 20) a cover plate steel reinforcement framework is built in the steel formwork; 40) foam fiber self-repairing concrete is poured into the steel formwork and vibrated to be uniform; and 50) the steel formwork is dismantled after pouring forming, and the prefabricated foam fiber self-repairing concrete public pipeline cover plate is obtained after natural curing. The cover plate prepared by the preparation method disclosed by the invention is light in weight, does not need to be matched with heavy machinery during construction and can be completed by a small amount of manpower. The cover plate is of a porous structure and is good in water permeability, water can be rapidly drained when the rainfall is suddenly increased, and urban flood disasters are reduced. The cover plate can be pre-prepared before construction, and during construction, the cover plate can be spliced and paved on a pipeline along the length direction of the pipeline, so that the construction is convenient. When the pipeline is maintained, only one piece of cover plate needs to be smashed or pried open, the other pieces of the cover plates can be uncovered in sequence, and the whole road surface does not need to be damaged.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of a prefabricated foam fiber self-repairing concrete public pipeline cover. Background technique [0002] Under the existing technical conditions, pipeline construction often requires mechanical excavation of the cement pavement on the surface of the pipeline. During this process, a lot of manpower and mechanical shifts were consumed, and at the same time, huge noise was generated, which greatly affected the surrounding environment; in addition, after the pipeline construction was completed, the concrete protective layer needed to be poured again. Due to the long curing time of concrete, After the pouring of the protective layer was completed, the road could not be quickly restored to use. With the development of the aging population, human resources are becoming increasingly scarce, and the labor costs of traditional pipeline mainten...

During this process, a lot of manpower and mechanical shifts were consumed, and at the same time, huge noise was generated, which greatly affected the surrounding environment; in addition, after the pipeline construction was completed, the concrete protective layer needed to be poured again. Due to the long curing time of concrete, The road cannot be quickly restored to service after the cover is poured

With the aging of the population, human resources are increasingly scarce, and traditional pipeline maintenance and construction labor costs are becoming increasingly high, and new technologies are needed to replace them to solve this problem
