Movable formwork cast-in-place beam maintenance method and maintenance system

Abstract

According to the movable formwork cast-in-place beam maintenance method and maintenance system, through a fixed spraying device and a movable spraying device, a beam body can be comprehensively maintained before and after walking of the movable formwork, the sustainability and the full coverage of maintenance are guaranteed, and therefore the solid quality of a box girder is guaranteed, and the maintenance cost of the box girder is reduced. Each maintenance spray head can be accurately controlled through a control unit and each electromagnetic valve, the spraying amount can be selected according to the weather state, intelligent spraying is achieved, and the beam surface spraying requirement is met; the standard spraying amount cardinal number, the weather state and the spraying adjustmentcoefficient can be preset according to the engineering location, the method can be suitable for construction environments under different geographical conditions, and the whole system has transportability and repeatability.

Description

technical field [0001] The invention relates to a maintenance method and a maintenance system for cast-in-place beams with mobile formwork, and belongs to the field of cast-in-situ beam construction with mobile formwork. Background technique [0002] At present, for the maintenance work during the construction of cast-in-place beams with mobile formwork, the main method is to cover the surface of the poured concrete with water storage materials and carry out regular manual watering maintenance. However, due to the large span, high temperature and long construction period of the mobile formwork cast-in-place beam project, and the artificial maintenance parts also have shortcomings such as large randomness and poor continuity, resulting in insufficient maintenance of the mobile formwork cast-in-place simply supported beam concrete The problem, which in turn easily affects the quality of the box girder entity, has potential safety hazards. In order to solve the problem of insu...

Problems solved by technology

However, due to the large span, high temperature and long construction period of the mobile formwork cast-in-place beam project, and the artificial maintenance parts also have shortcomings such as large randomness and poor continuity, resulting in insufficient maintenance of the mobile formwork cast-in-place simply supported beam concrete problems, which will easily affect the quality of the box girder entity, and there are potential safety hazards

In order to solve the problem of insufficient maintenance, in the actual process of the construction of cast-in-place beams with mobile formwork, the method of continuous watering and maintenance during the construction period is often adopted, which is prone to excessive maintenance and waste of water
