Analysis on the Causes of Indoor Ground Slab Settlement of a Workshop in Ningbo and the Treatment Methods

摘要:

针对宁波市宁海县宁东区块某厂房室内地坪沉降现象，在分析沉降原因和沉降趋势的基础上，结合本工程的具体条件对几种加固方法进行了对比，确定采用锚杆桩 梁板结构加固方式对地坪进行处理。研制了多功能小型静力压桩机、采用了小创面多级挤扩贯穿排障法等解决了施工中的难题，实现了复杂环境条件的特种专业工程的顺利施工。治理效果良好。

Abstract:

According to a workshop indoor ground slab settlement in Ningbo, based on the analysis on the settlement reasons and trend, the comparison is made on several reinforcement methods by considering the special conditions of this project, anchor pile beam-slab structure is determined to be adopted to deal with the indoor ground slab settlement. A multifunctional small static pile driver is developed, multi-stage extrusion and expansion thorough backfill method is used with small ground surface damage to solve the construction difficulties and realize the smooth construction of special engineering project in complex environment conditions. This project treatment has achieved good effects.
