大体积混凝土结构多路温度巡检系统 Multi-channel temperature inspection system for mass concrete structures

技术领域 technical field

本发明涉及建筑行业中的一种混凝土结构温度检测设备，尤其是一种大体积混凝土结构多路温度巡检系统。The invention relates to a concrete structure temperature detection device in the construction industry, in particular to a multi-channel temperature inspection system for a large-volume concrete structure.

背景技术 Background technique

混凝土结构在现代工程建设中有着广泛的应用，比如工业建筑中的大型设备基础、大型构筑物的基础、高层、超高层和特殊功能建筑的箱型基础、有较高承载力的桩基厚大承台等都是体积较大的钢筋混凝土结构。在上述各种结构的混凝土结构浇筑后，其内部温度会升高，温度升高主要是由于水泥在水化过程中放出的热量，在建筑行业中该温度变化一般为20～30°，甚至更高。该温度变化产生的温度应力是造成混凝土结构产生裂缝的主要因素，温差愈大，温度应力也愈大，而且混凝土结构自然散热时需要较长的时间。Concrete structures are widely used in modern engineering construction, such as large equipment foundations in industrial buildings, foundations of large structures, box foundations for high-rise, super high-rise and special function buildings, thick pile foundations with high bearing capacity Platforms are large reinforced concrete structures. After the concrete structures of the above-mentioned various structures are poured, the internal temperature will rise. The temperature rise is mainly due to the heat released by the cement during the hydration process. In the construction industry, the temperature change is generally 20-30°, or even higher. high. The temperature stress generated by this temperature change is the main factor causing cracks in the concrete structure. The greater the temperature difference, the greater the temperature stress, and it takes a long time for the concrete structure to dissipate heat naturally.

随着我国经济的迅速发展，工程建设规模越来越大型化，在普通工业与民用建筑中大体积混凝土结构(根据高层建筑施工手册的有关规定：单面散热的结构断面在750mm以上双面散热在1000mm以上水化热引起混凝土内外温差在25”C以上的混凝土结构可称为大体积混凝土结构)大量出现。由于其体积庞大，一次性浇筑量大，工程条件复杂，如果施工措施控制不力，较大的温度差极易产生各种混凝土结构裂缝，轻者会影响混凝土的耐久性，重者还会严重影响混凝土的力学性能，研究证明对水泥硬化过程中的温度进行控制，可有效防止裂缝的发生。With the rapid development of China's economy, the scale of engineering construction is becoming larger and larger. In general industrial and civil buildings, large-volume concrete structures (according to the relevant regulations in the construction manual of high-rise buildings: the structural cross-section of single-sided heat dissipation is above 750mm and double-sided heat dissipation Concrete structures with a temperature difference between the inside and outside of the concrete above 25"C caused by the heat of hydration above 1000 mm can be called mass concrete structures) appear in large numbers. Due to their large volume, large amount of one-time pouring, and complex engineering conditions, if the construction measures are not well controlled, A large temperature difference can easily produce various concrete structure cracks. The light ones will affect the durability of the concrete, and the severe ones will seriously affect the mechanical properties of the concrete. Research has proved that controlling the temperature during the cement hardening process can effectively prevent cracks happened.
