Cooling method of mass concrete vibration

Abstract

The invention relates to the field of seabed immersed tunnel construction, in particular to a cooling method of mass concrete vibration. The method includes: a first air cooler is mounted on a top plate reinforcement cage, second air coolers are respectively mounted on two outer wall form boards, and the first air cooler and the second air coolers are communicated into a reinforcement cage form board through hoses. The method has the advantages that the air coolers are respectively mounted on the top plate reinforcement cage and the two outer walls, the air coolers are connected with the corrugated hoses communicated into the reinforcement cage, cold air is conveyed to lower vibration environment temperature, a cool vibration environment is provided to vibration workers, and vibration quality is increased; the method is simple in equipment, convenient in equipment mounting and demounting and high in cooling efficiency; meanwhile, the mounting positions of the air coolers are reasonable and effectively, the communicating positions of the corrugated hoses conveying the cold air are evenly distributed along the length of the reinforcement cage, evenly cooling inside the reinforcement cage is achieved, and smooth construction is guaranteed.

Description

technical field [0001] The invention relates to the construction field of submarine immersed tube tunnels, in particular to a cooling method for large-volume concrete vibrating operations. Background technique [0002] At present, with the need for large-volume concrete construction, for example, in the construction of the immersed tube tunnel of the Hong Kong-Zhuhai-Macao Bridge, the concrete of the immersed tube section is poured at one time, and each section of concrete is about 3300m 3 , and when pouring concrete in sections, there are airtight steel formwork around, and criss-cross steel bars in the middle. During the vibrating operation, the space for workers to vibrate is narrow, and the solidification of concrete produces a large amount of hydration heat, which makes the inside of the steel cage It has become a "sauna room", especially when vibrating the outer wall and middle wall of the steel cage, workers need to enter the steel cage to vibrate, and work continuous...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a cooling method suitable for large-volume concrete vibrating operations, to solve the problem that the ambient temperature inside the steel cage is too high during the large-volume concrete vibration operation, and the cooling effect is not good when the fan is installed. It is difficult to install, or the cost of installing a large number of fans is high and it is not easy to maintain.
