Cooling device and cooling method for concrete pumping pipeline under high temperature

Abstract

The invention relates to a high-temperature concrete pumping pipeline cooling device and a cooling method thereof. The cooling device is characterized in that the cooling device comprises steel ice, a sleeve and a thermal insulating layer, the steel ice integrally comprises refrigerating fluid and a stainless steel shell, the refrigerating fluid comprises edible alcohol and purified water, the stainless steel shell is set into a ball or cylinder, a hollow structure is arranged inside the stainless steel shell and filled with the refrigerating fluid, the sleeve comprises an inner pipe, an outer pipe and an arc slab, the arc slab is welded between the inner pipe and the outer pipe to form spaced arc grooves for placing the steel ice, the steel ice is slidably arranged in the arc grooves, and the thermal insulating layer wraps the outside of the sleeve. The cooling device is connected with a pumping pipeline, heat generated by friction between concrete and the pipeline and heat generated by hydration of the concrete are evenly absorbed, and the temperature of the pumping pipeline and the temperature of the concrete are reduced by the aid of the steel ice, so that the temperature of casting concrete is kept within a specified range.

Description

technical field [0001] The invention relates to a cooling device for a concrete pumping pipeline under high temperature and a cooling method thereof. Background technique [0002] With the development of social economy, concrete is widely used in various engineering sites, and the main body of various buildings (structures) stands in the city. However, concrete structures have their unavoidable defects, cracks will appear under the influence of temperature. In the high temperature weather in summer, the high temperature environment of the construction site increases the temperature of the concrete exit machine and the temperature of the pumping pipeline exposed to the sun. When concrete is pumped, frictional heat is generated between the concrete and the pumping pipe, and the moisture in the concrete lubricating film is eroded and evaporated due to the high temperature and the frictional heat of the pipe wall. This is the reason for the increase in the temperature of the co...

Problems solved by technology

This method is time-consuming and labor-intensive. In high-temperature weather, water needs to be continuously sprinkled to cool down. It requires high labor intensity for workers and requires a large amount of water. It will cause sewage to flow around the pipeline, pollute the environment, and is not conducive to civilized construction.

Moreover, the amount of evaporation is large in a high-temperature environment, and the air humidity in the construction site increases due to the evaporation of cooling water, which makes the on-site workers feel uncomfortable and affects the physical and mental health of the workers.
