技术介绍
近些年,由于对建筑物本身的功能要求越来越高,建筑物的安装设计越来越复杂,牵涉的相关专业也越来越多,而各专业设计过程中很难做到周密和细致的考虑,管线排布存在着排布乱,空间利用不合理等问题,这不仅影响建筑装饰效果,甚至影响使用和维护保养。管线综合平衡技术的应用较好地解决了建筑物空间的合理利用,增强管线布置的合理性,但相对于设计复杂和管线量大的大型项目来说,由于其功能要求可能导致各层空间分割均不相同,公共空间分块分片,交叉分布,管线平衡很难做到系统和深入,为此施工前如何做好管线平衡尤为重要。传统施工现场临时水、电管线埋地敷设,前期挖沟、填埋施工大量机械台班,且维修时还需重新挖填土,裸露土较多,无法覆盖或覆盖不到位,且浪费大量机械台班,很多情况下电缆、水管回收率较低或根本就没有回收价值。本工法通过现场策划,将临时施工管线综合合理排布,即解决了因场地狭小,基坑较深带来的制约问题也得以解决,同时现场临时水电 ...
