滨海盐碱地铺装工程泛碱现象立体防护措施

Three-dimensional Protection Measures for Pan-alkali of Coastal Saline-alkali Paving Works

园林工程中,石材铺装后的泛碱现象一直困扰着许多园林工作者。泛碱现象是我国滨海盐碱地地区园林铺装工程中常见现象,其直接导致石材装饰功能受到影响,降低园林景观效果。造成泛碱现象的直接原因是施工方施工不规范及监理方缺乏监管责任意识。以天津滨海地区园林铺装工程为例,从分析泛碱现象的机理与成因入手,结合铺装工程施工过程,特别是基层、结合层、面层施工要点,较系统地阐述解决泛碱现象的立体防护措施,为创造优美的园林景观效果提出建设性意见。

In garden engineering,the phenomenon of pan-alkali after the paving construction has plagued many garden workers.It is more common in the pavement works of coastal saline-alkali areas in China,which directly affects the stone decoration function,thus reducing the landscape effect.The direct cause of pan-alkali phenomenon is the non-standard construction of construction workers and the lack of awareness of regulatory responsibility of supervisors.By taking the Tianjin coastal area garden pavement project as an example,from the cause of pan-alkali phenomenon analysis,combining with the pavement construction process,especially the base,boundation,surface construction points,this paper systematically elaborates protective three-dimensional measures for the phenomenon of pan-alkali to provide suggestions on creating more beautiful landscape effects.
