摘　　要：建筑工程基础底板通常设有集水坑、承台坑或局部降板等,底板防水施工前需先施工集水坑、承台坑等侧壁胎膜。重力式混凝土胎膜技术是通过混凝土的自身重力抵抗土的侧向压力,保证胎膜的结构稳定,保证施工安全。通过某工程项目中的研究与实践,主要介绍了砂土地基中胎膜方案的选型,通过对比选用重力式混凝土胎膜,详细介绍了重力式混凝土胎膜的施工方法。There are usually sump pits,cap pits,sectional descending boards,etc.on the engineering foundation slab.The sidewall molds of sump pits,cap pits,etc.need to be constructed firstly before the waterproof construction of the foundation slab.The gravity concrete mold technology uses the concrete’s own gravity to resist the lateral pressure of soil,so as to ensure the stability of the mold structure and the safety of the construction.This paper mainly introduces the selection of the mold schemes in sand foundations based on the research and practice in an engineering project,and introduces the construction method of the gravity concrete mold in detail by comparing the selection of the gravity concrete molds.
