Thermal insulation measures for coal bunker slipform construction in winter

Coal bunker slipformConstruction is generally not carried out in winter, but under special circumstances, the winter coal bunker slip form construction can be realized through reasonable measures and arrangements. So what are the precautions for slipform construction in winter? Next, the editor will bring you knowledge about thermal insulation measures for coal bunker slipform construction in winter, and I hope it will be helpful to everyone.

According to the engineering characteristics and environment of coal bunker slipform construction, the use of thermal insulation system should be comprehensively considered:

1,For the insulation of the template, after the installation of the sliding template is completed, you must remember to spray the back of the templatePolyurethane foam about 75px thick, which can be used as a template insulation layer. When spraying, spray evenly and avoid any missing spray. After the polyurethane foam is solidified, the electric blanket should be hung close to the polyurethane insulation layer, and it must be side-by-side with no gaps left. Heating the template directly can effectively improve the thermal insulation and cold-proof function of the template.

2,For electric heating sheds, a suitable rock wool quilt should be customized according to the height of the outer hanger of the formwork and the height of the platform guard rail, and then fix the upper end of the rock wool quilt on the sliding form platform guard rail, and the lower end should hold the outer hanger Cover the coal bunker wall with the end of the rock wool quilt to form a closed space. Also remember to place every otherAn electric heater is placed 2m away, and the electricity must be energized for 2 hours before pouring concreteabout. Two windproof skirts should be hung on the guardrail of the sliding form platform and the outer hanger to keep warm. After the concrete is calendered, two layers of thin form curing liquid should be applied to form a thin form. The role of windshield and heat preservation.

3.The internal heat preservation of the coal bunker, the heat preservation inside the bunker will be simpler than that on the outside. First, the openings used are sealed with cotton felt, and then a heat source is set for heating, so that the temperature in the bunker will rise, because the height of the bunker can reduce the heat source Rise together with the sliding platform.
