Problems solved by technology
The construction of high piers often adopts the mold-turning method, and the construction is greatly affected by the ambient temperature. When the temperature is high in summer, the concrete loses water quickly and easily cracks. When the temperature is low in winter, the concrete needs to be maintained for heat preservation. Blanket and warm water mixing methods have poor thermal insulation effect and the construction process is cumbersome

The invention discloses a concrete temperature control device in high pier rollover construction, a high pier is provided with a template, a steel strand is arranged between the template and a frame ladder cage, the temperature control device comprises a temperature adjusting mechanism and a temperature control water pool, the temperature adjusting mechanism comprises a plurality of temperature adjusting assemblies, the plurality of temperature adjusting assemblies are sequentially wound on the periphery of the template in the vertical direction. Every two adjacent temperature adjusting assemblies are communicated through a plurality of quick connectors, and the temperature adjusting assembly arranged on the bottommost layer is connected with the temperature control water pool through a connecting pipe. The temperature control pool comprises a pool body, a water pump and a heating plate, wherein the water pump and the heating plate are arranged in the pool body; one end of the connecting pipe is connected with the temperature adjusting assembly, and the other end of the connecting pipe is connected with the water pump. The influence of temperature difference on high pier construction is reduced, and all-weather and all-season construction capacity is achieved.
Description
technical field [0001] The invention relates to the technical field of bridge engineering construction, in particular to a concrete temperature control device in the formwork construction of high piers. Background technique [0002] With the rapid advancement of highway and railway construction in our country, a large number of high-pier bridges have been built in the mountains and deep valleys with steep terrain and large drop. The construction of high piers often adopts the mold-turning method, and the construction is greatly affected by the ambient temperature. When the temperature is high in summer, the concrete loses water quickly and easily cracks. When the temperature is low in winter, the concrete needs to be maintained for heat preservation. Blanket, warm water mixing method has poor thermal insulation effect, and the construction process is cumbersome. In order to control the influence of temperature difference on concrete construction and improve the quality of p...
