Intelligent maintenance system for concrete outer wall

Abstract

The invention discloses an intelligent maintenance system for a concrete outer wall. The intelligent maintenance system comprises a water collection tank, a heat-preservation tank, an intelligent water level system, an intelligent temperature control system, an alarm system and a wall maintenance system. The intelligent water level system comprises a water control center, a flow controller and a water level sensor; the intelligent temperature control system comprises a temperature control center, a temperature detection device and a heating device; the alarm system comprises a display and an alarm; and the alarm system is in feedback connection with the temperature control center and the water control center. According to the intelligent maintenance system for the concrete outer wall, intelligent water level control and intelligent temperature control are adopted in the whole course, the labor cost is largely saved, and the outer wall is fully maintained; and the temperature and the flow of maintenance water are adjusted along with the changes of the outer wall temperature, the maintenance quality of the concrete outer wall is improved, the crack risk of the concrete outer wall is reduced, and the durability of a concrete structure is improved.

Description

technical field [0001] The invention belongs to the technical field of concrete, and more specifically relates to an intelligent maintenance system for concrete exterior walls. Background technique [0002] The cementitious material in concrete releases a lot of heat during the hydration process. Due to the unique physical characteristics of concrete, there is a large temperature difference between the inside and outside of the concrete, and the binding force generated by the concrete during the hardening process, resulting in a large temperature stress in the concrete. . According to academician Wu Zhongwei of the famous Academy of Sciences in my country (D is the total shrinkage and deformation value of concrete, ε 2 is the limiting expansion rate of concrete, S t is the concrete temperature shrinkage rate (cold shrinkage rate), ε y（t） is the maximum drying shrinkage (shrinkage rate) of reinforced concrete at any time, S k is the ultimate tensile value of reinforced ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are mainly several maintenance methods for concrete wall maintenance: one is direct watering maintenance, which is the most primitive maintenance method, with low labor efficiency, uneven maintenance, and serious waste of water resources. The low-temperature water curing of the wall is more harmful to the wall; one is to cover the surface of the wall with a plastic film after the concrete is removed from the formwork. This method has almost no effect on the temperature drop of the concrete except to prevent the moisture from dispersing in the concrete; It is to spray the film-forming curing agent on the outside of the concrete after the concrete formwork is removed. This kind of curing agent is costly, and the concrete curing is not timely, and there are no timely and effective measures during the heating process of the concrete.
