在现有工业企业的改建中,建筑界面临两个急需解决的问题。一个是由于新增重型的生产设备,增加层间楼盖或房屋加层,必须提高地基和基础的承载能力,另一个是在扩大企业的生产面积时,在现有建筑物附近新建厂房,在施工新厂房基础工程时,必须保证现有建筑物和构筑物的稳定性,避免引起过大的不均匀沉陷。使用普通现浇混凝土和钢筋混凝土结构的方法解决地基基础的加固问题,因要开挖大量的土方,
In the reconstruction of existing industrial enterprises, the construction industry faces two problems that need to be solved urgently. One is that due to the addition of heavy-duty production equipment and the addition of floor slabs or house additions, the carrying capacity of foundations and foundations must be increased. The other is to build new factories near the existing buildings when expanding the production area of enterprises. When constructing a new plant foundation project, the stability of existing buildings and structures must be ensured to avoid causing excessive uneven settlement. The use of ordinary cast-in-place concrete and reinforced concrete structures solves the problem of reinforcement of foundations due to the large amount of earthwork to be excavated.
