Retractable folding-type intelligent maintenance device for concrete

Abstract

The invention belongs to the field of construction devices for roads and bridges, and particularly relates to a retractable folding-type intelligent maintenance device for concrete. The retractable folding-type intelligent maintenance device for the concrete is composed of a water supplying system, a spraying system, a lifting system, a monitoring system and a control system; an electric scissor-type lifting platform lifts the monitoring system, the monitoring system acquires data by monitoring a concrete pier to be maintained and transmits the data to the control system, and the control system enables the water supplying system and the spraying system to spray water on the concrete pier according to the data transmitted by the monitoring system. The electric scissor-type lifting platform can lift the spraying system to a required height for conducting spraying conveniently; after the retractable folding-type intelligent maintenance device is folded, more convenience is provided for transportation among different fields and long-distance transport.

Description

technical field [0001] The invention belongs to the field of road and bridge construction devices, and in particular relates to a retractable and foldable intelligent maintenance device for concrete. Background technique [0002] Poured concrete needs to be cured after solidification to keep the surface of the concrete moist, so as to ensure that the hydration and hardening of the cement can proceed smoothly. If the maintenance is not carried out in time, when the concrete surface loses water, the hydration reaction of the cement will stop, and the surface will dry and shrink at the same time. Under the action of shrinkage stress, the concrete structure will produce cracks, which will affect the structural strength, safety and normal use. [0003] At present, the maintenance of ultra-high bridge piers and beam-column concrete structures has the following problems: [0004] 1) The method generally adopts artificial water spraying maintenance. Now most construction sites use ...

AI Technical Summary

Problems solved by technology

[0004] 1) The method generally adopts artificial water spraying maintenance. Now most construction sites use manual watering at regular intervals. The watering method is mainly artificially spraying water with a high-pressure water gun on the upper end of a super-high bridge pier or beam column or lowering it to be maintained with a hanging cage. Concrete is sprayed on the surface of the pier. This method will generate a lot of water on the ground, making the maintenance site muddy and inconvenient for other processes;

[0005] 2) Due to the quality and experience of the maintenance workers, the quality of maintenance has a large difference;

[0006] 3) With the expansion of the construction scale of roads and bridges, the artificial water spray maintenance method can no longer meet the demand, and it is easy to miss the maintenance phenomenon, which will cause cracks in the pier pier body, cause safety hazards, affect the quality of the project, and reduce the use of the pier At the same time, the labor intensity of the workers is high, the safety risk is high, and the operation efficiency is low.
