摘要
在城市建设过程中,经常会遇上成堆成片的杂填土,一般的施工方法是对杂填土进行特殊处理如重锤强夯、全部换填等方式。重锤强夯对周边环境的影响大,在城市居民生活区中将受到较大的限制;全部换填要花费挖运杂填土、外购回填土等大量费用,同时还会带来新的环境污染(杂填土堆放)和破坏生态环境(大量挖山)等问题。结合厦门市高殿二号路路基填筑实际,简要介绍分层碾压杂填土处理的方法及施工情况,并对杂填土的分检、摊铺、分层碾压等施工工艺、质量控制指标以及试验检测后的效果进行介绍,以供大家参考。
During the construction of city, there are many mixed backfill. Tamping by heavy hammer and replacement are the most ordinary disposal measures for the mixed backfill. But tamping badly affect the life of the resident around, and the cost of replacement is very expensive. At the same time, there are many problems such as pollution and wreck of entironment. In this paper, the construction technique of mixed backfill such as inspection, spread, and grinding etc., is introduced base on the construction of the roadbed in Gaodian 2 road, Xiamen city. The quality control standard and experimental result are also presented here. It has reference meaning for the similar problems about mixed backfill.
