Special hanging basket for dam thermal insulation construction in severe cold area

Abstract

The invention relates to the technical field of high-altitude construction hanging baskets, and discloses a special hanging basket for dam thermal insulation construction in a severe cold area, whichcomprises a fireproof hanging basket and a telescopic fireproof body; and a construction opening is formed in the front side surface of the fireproof hanging basket,the telescopic fireproof body is mounted on the construction opening, a far infrared heater is mounted in the fireproof hanging basket near the side of the construction opening, and the heating end of the far infrared heater faces toward the construction working surface of a dam bodythrough the construction opening. The structure of thespecial hanging basket for dam thermal insulation construction in the severe cold area is reasonable and compact,and by arrangingthe fully enclosed fireproof hanging basket and the telescopic fireproof body, a relatively closed working space can be formed in the fireproof hanging basket; and evenif in a frozen and snow-covered land, the construction working surface of the dam can be heated and dried through the far infrared heater,and the construction process is unaffected by windy, frosty,rainy, and snowy weather; anda lighting device and a ventilation device are internally arranged in the fireproofhanging basket, all-weather construction is truly realized, and the restriction of the natural environment does not exist.

Description

technical field [0001] The invention relates to the technical field of a high-altitude construction hanging basket, which is a special hanging basket for dam insulation construction in severe cold regions. Background technique [0002] Spraying polyurethane rigid foam on the surface of the dam body as an insulation layer has become a new technology for water conservancy dam construction in cold regions. This technology can control the temperature gradient on the surface of the dam, reduce the temperature stress inside and outside the dam, and greatly reduce the appearance of dam concrete. The probability of cracks provides a reliable guarantee for the safe operation of the reservoir. Spring and summer are generally the flood seasons of the dam. In the dry season, in order to ensure the quality of the spraying of the dam insulation layer, it is generally selected for a short period of time before the winter, because the weather conditions are good and the temperature is high ...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a special suspension basket for dam insulation construction in severe cold areas, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem that the existing suspension basket cannot perform thermal insulation construction work on the dam in winter, which is affected by changes in external temperature and wind speed. The impact is greater, and construction cannot be carried out around the clock, and the construction efficiency is very low.
