Full-process intelligent temperature control system and method for large-volume concrete

Abstract

The invention discloses a full -process intelligent temperature control system for large-volume concrete, and the system can achieve the automatic sensing, transmission, interconnection, sharing and control of full-process temperature control information of mixing, transportation, warehousing, closing-out, vibrating, maintaining, water cooling and joint grouting of concrete raw materials, thereby achieving the full-element and full-process management of temperature control and crack resistance based on the technologies of the Internet and Internet of Things, effectively protecting the large-volume concrete from cracking, and improving the construction quality of concrete. The system comprises an aggregate intelligent pre-cooling temperature control unit, a concrete intelligent mixing temperature control unit, a concrete pouring cabin internal small environment unit, a concrete intelligent water cooling unit, a concrete exposure face intelligent maintenance unit, a concrete exposure face intelligent heat preservation unit, an intelligent joint grouting unit, and a control center. The invention also provides a control method.

Description

technical field [0001] The invention belongs to the technical fields of water conservancy and hydropower engineering, nuclear power engineering, port engineering, etc., and specifically relates to an intelligent temperature control system for the whole process of large-volume concrete, and a method using this system, which is mainly used for crack prevention and construction of large-volume concrete Quality Management. Background technique [0002] Crack control has always been one of the difficulties in mass concrete construction. The theoretical research and engineering practice of temperature control and crack prevention began in the 1930s. After decades of development, the engineering community has gradually established a relatively complete set of temperature control and crack prevention theoretical systems, forming a relatively systematic concrete Temperature control and anti-cracking measures include improving the crack resistance of concrete, dividing joints into bl...

AI Technical Summary

Problems solved by technology

The causes of concrete cracks are complicated, mainly in terms of structure, materials, construction, etc. One of the important reasons is that poor information leads to inadequate measures and management, that is, the "four nos" of information acquisition - untimely, inaccurate, untrue, not systematic

At the same time, due to the artificial control method, the construction quality is often greatly affected by the quality of the on-site engineering personnel, resulting in a large deviation from the design state, resulting in the "four major" problems of temperature-controlled construction, namely: large temperature difference, large cooling range, The cooling rate is large and the temperature gradient is large, which eventually leads to the generation of concrete cracks
