水利工程冬季施工供热及热工计算

Heat supply and thermotechnical calculation for water project winter construction

在东北地区 ,为赶工期 ,许多中小水利枢纽工程采取冬期施工是必要的。沈阳市浑南灌区渠道枢纽引水复建工程 ,为保证冬期施工质量采取以暖排法为主的综合供热方式进行保暖增温。作者以该工程为例 。

It is necessary to construct in winter to catch the time limit for most of medium and small water projects in the northeast region. For the guarantee of construction quality in winter, the diversion pivot reconstruction project at Shenyang city Hunnan irrigation district had taken multipurpose heat supply measures, which the warm-discharge method is as the dominant measure, to protect keep warm and increase temperature. Taking the project for example, the paper introduces heat supply and thermodynamics calculation in winter construction. [
