Background
Temperature control anti-cracking is an important research content and an effective means for reducing the cracking risk of mass concrete buildings and increasing the structural safety of the mass concrete buildings. One of the main reasons for cracking of concrete buildings during construction is that the thermal stress caused by excessive temperature difference between the inside and outside of the building is far higher than the bearing capacity of the concrete, so that effective temperature control and crack prevention measures must be taken in the large-volume concrete buildings during construction. The 'external protection and internal communication' is one of the core ideas of temperature control anti-cracking means. The external protection is that the thermal insulation material is paved on the external surface of the concrete building, so that the direct heat exchange coefficient of the concrete and the surrounding environment is reduced, and the rapid cooling of the surface of the concrete is avoided; the inner pipe is formed by pre-embedding a cooling water pipe before concrete pouring according to a temperature control design scheme, and a large amount of heat generated by cement hydration heat in the concrete is taken away through circulating cooling water, so that the maximum temperature of the concrete building which possibly appears originally is reduced. The purpose of both measures is to reduce the temperature difference between the inside and the outside of the concrete, so that the thermal stress generated by the structure is within the allowable range of engineering design.
The PE/PP pipe has the advantages of low cost, good corrosion resistance, relatively high flexibility, portability, easiness in installation and fixation and the like, and is one of main preferable pipes for a 'internal connection' measure of a temperature control anti-cracking measure. The cooling water pipe needs to be embedded and fixed according to the related temperature control anti-cracking design requirements before the concrete begins to be poured, and in the concrete pouring process later, the vibrating rod is often needed to assist in construction so as to improve the fluidity of the concrete and further improve the pouring quality of the concrete. Along with the pouring process advances, the constructor who operates the vibrating rod will hardly accurately judge the condenser tube that has buried in the concrete, and the condition that the vibrating rod directly acts on condenser tube is very likely to take place, causes condenser tube skew target cooling position, damage or even fracture for the concrete cooling effect is discounted or the condenser tube leaks in the concrete that has pour, and then influences construction quality and construction progress. Therefore, in the concrete pouring process, the spatial position of the cooling water pipe is identified in real time and definitely, and the vibrating position is judged by an operator for assisting the vibrating rod, so that the direct action of the vibrating rod on the cooling water pipe in the construction process is avoided, and the concrete pouring method has important engineering significance.
