哈尔滨防水分析地下工程如何防水？

1、哈尔滨防水http://hrbfangshui.hbugo.com/介绍排水减压法是在建筑物底下做出盲沟，创造自流排水的条件，当无自流条件时，可通过盲沟将水引入集水井中，再用水泵抽排引走，减少水对地下工程的渗压，起到防水作用。
Jinan water drainage decompression method is introduced to make a blind ditch underneath the building, creating gravity drainage conditions, when there is no gravity conditions can be introduced through the blind ditch water collection wells, then pumping the water pump lead away, reducing water osmotic pressure of underground engineering, played the role of water.

2、哈尔滨防水谈到防水混凝土结构防水，这是采用提高混凝土密实性的办法，提高结构混凝土的抗渗性，还可满足一定的耐冻融和耐侵蚀的要求。
Speaking Jinan waterproof waterproof waterproof concrete structure, which is adopted to improve the compactness of concrete ways to improve the impermeability of the concrete structure, but also meet the requirements of a certain

resistance to freezing and thawing and erosion resistant.

3、哈尔滨防水分析刚性抹面防水，这是采用防水水泥砂浆或掺外加剂的防水水泥砂浆对建筑物进行抹面而达到抗渗目的的一种方法。
Jinan analysis of rigid waterproof waterproof plaster, which is mixed with waterproof cement mortar or cement mortar admixture waterproof plaster of buildings to achieve a method of impermeability purposes.

4、哈尔滨防水http://hrbfangshui.hbugo.com/建议金属层防水，这是在防水建筑的内部，焊贴一层金属板以达到抗渗防漏目的的一种方法。这种方法适用于防水要求较高的工程。
Jinan waterproof recommendations metal layer waterproof, which is inside the waterproof construction, welding a metal plate affixed to a method to achieve the purpose of the impermeability barrier. This method is suitable for the higher

water requirements engineering.
