The cushion cap cooling pipe is a kind of cooling pipe used for cushion cap concrete pouring, which is mainly used to reduce the temperature of the cushion cap concrete, reduce the temperature stress inside the concrete, and prevent quality problems such as cracks in the cushion cap. The common specifications of the cushion cap cooling pipe include diameter, length, spacing and other parameters, and the specific specifications are determined according to the design and construction requirements of the cushion cap.
In the process of pouring concrete on the cushion cap, due to the influence of cement hydration heat, the internal temperature of the concrete will rise rapidly, resulting in the increase of the internal temperature stress of the concrete. If the temperature stress exceeds the tensile strength of the concrete, quality problems such as cracks can occur. Therefore, in the process of pouring the concrete of the cushion cap, temperature control and heat dissipation treatment are required to reduce the temperature and temperature stress inside the concrete.
The main function of the cushion cap cooling pipe is to reduce the temperature of the cushion cap concrete. Before the concrete pouring of the cushion cap, the cooling pipe is arranged inside the cushion cap according to the design requirements, and the cooling water is introduced in the pouring process, and the heat inside the concrete is taken away through the circulation of the cooling water, so as to reduce the temperature of the concrete. At the same time, after the concrete pouring of the cushion cap is completed, the internal temperature of the concrete can be slowly reduced and the temperature stress can be reduced through the adjustment and control of the cooling pipe.
Common specifications of cushion cap cooling pipes include parameters such as diameter, length, and spacing. The diameter is usually between 10mm and 30mm, and the length is determined according to the design and construction requirements of the cap, which is generally longer to cover the entire cap. The spacing is determined according to the size of the cushion cap and the heat dissipation requirements, and is generally controlled between 1m and 2m. At the same time, in order to improve the cooling effect, measures such as multi-stage cooling pipes or increasing the number of cooling pipes can also be adopted.
When using the cushion cap cooling pipe, the following points need to be noted: first, the cooling pipe should be arranged according to the design requirements to ensure that the number and position of the cooling pipe meet the requirements;Secondly, in the pouring process, it is necessary to keep the circulation of cooling water smooth to avoid problems such as blockage or water leakageFinally, after the pouring is completed, the cooling pipe should be adjusted and controlled in time to ensure that the internal temperature of the concrete is slowly reduced.
In a word, the cushion cap cooling pipe is an important construction equipment, which can effectively reduce the temperature and temperature stress of the cushion cap concrete, and prevent quality problems such as cracks in the cushion cap. When using the cushion cap cooling pipe, it is necessary to pay attention to the problems of layout according to the design requirements, keeping the cooling water circulating smoothly, and timely adjustment and control.
