地下室外墙后浇带施工的传统方法以砖砌挡土墙作为回填土与后浇带的隔离,待到符合设计要求时间后,安装模板浇注混凝土,拆模后进行防水层施工,拆除挡土墙后再回填此处土方。这样施工,后工序是前工序的必要条件,施工周期长。为保证地下室结构施工后及时进行外墙防水,更早进行回填土施工,保证基坑安全稳定,地下室外墙后浇带拟采用预制细石混凝土板作为其外侧的模板,提前封闭外墙后浇带。采用此种方法施工,既工序安排合理,节约工期,又使外墙防水和回填土施工保持连续性,并能保护后浇带钢筋不被破坏。
The basement wall after pouring with the traditional method of construction of brick retaining wall as the backfill soil and post-pouring with the isolation until the time required to meet the design requirements, the installation of template pouring concrete, demolition of the waterproof layer after construction, demolition of retaining Backfill the earth here after the wall. This construction, after the process is a necessary pre-process conditions, the construction period is long. In order to ensure the waterproofing of the external wall after the construction of the basement structure in time, the backfill construction should be carried out earlier to ensure the safety and stability of the foundation pit. The post-pouring basement exterior wall is intended to adopt the prefabricated fine stone concrete slab as the template on the outer side, band. By this method of construction, both the process is reasonable arrangements, saving time, but also to make the construction of the outer wall waterproofing and backfill continuity, and can protect the post-pouring steel bar is not damaged.
