城市更新和灾后重建

工程设施经过一段时间的运行,不可避免地会发生混凝土和钢结构的老化和性能下降。为了延长其使用寿命,需要进行维护。

2015年,全球钢铁产量超过10万亿元人民币,混凝土产量超过250万亿元人民币,而这些数字仅仅是一年的时间#输出。钢铁材料和混凝土产品已经使用了100多年,现有的市场库存非常庞大。

钢材生锈和混凝土老化是世界范围内普遍存在的问题。目前,在钢结构和混凝土中没有有效的技术来解决这些问题。大多数老旧的钢结构和混凝土结构必须被废弃和替换。然而,报废和更换的高成本使得这种解决方案不可行。许多事故发生时,除了听之任之,别无他法。钢结构的主要问题是腐蚀;混凝土的主要问题包括漏水、开裂、碳化、冻损、蜂窝、强度等。

正赛盾拥有超过10年的欧美跨国公司咨询经验,专业从事混凝土和钢材维修20年,积累了数万个国内外工程实践案例。拥有发明专利和实用新型专利近40项,在国内外期刊上发表论文,主导或特约编辑近20项标准,创造性地解决了许多工程难题。

在一个1万平方米的地下车库里,水正在通过垫层渗出。在顺层浇筑多余的智能P30混凝土,但将混凝土冲刷出,形成约10mm的空腔。令人惊讶的是,12个小时后,人们发现原来漏水的洞已经不漏水了。——张家口工程
