1、基坑周圍的地面水應(yīng)加以排除或控制，使其不流入基坑，同時(shí)要準(zhǔn)備好排水措施，以防基坑中雨水積聚。用冷粘法施工的卷材防水層，施工完畢后還需留下排水裝置，繼續(xù)排水7d以上，以保證膠粘劑的充分固化，避免因過早撤掉排水裝置而導(dǎo)致地下水上升到防水層、水壓頂開卷材搭接部位的膠粘劑和密封膏，造成滲漏或鼓泡現(xiàn)象。
Surface water around the pit should be excluded or control, it does not flow into the pit, and to be ready to drainage measures to prevent the accumulation of rainwater pit. Cold bonding method of construction waterproofing membrane, the need to leave after the completion of construction of drainage devices continue to drain 7d above, in order to ensure adequate curing adhesives to avoid prematurely removed the drain which led up to the waterproof layer of groundwater, water pressure lap top open coil parts adhesives and sealant, resulting in leakage or bubbling phenomenon.
2、 金屬層防水。這是在防水建筑的內(nèi)部，焊貼一層金屬板以達(dá)到抗?jié)B防漏目的的一種方法。這種方法適用于防水要求較高的工程。
This is inside the waterproof construction, welding a metal plate affixed to achieve a leak-proof method impermeability purposes. This method is suitable for high water requirements engineering.
3、剛性抹面防水。這是采用防水水泥砂漿或摻外加劑的防水水泥砂漿對建筑物進(jìn)行抹面而達(dá)到抗?jié)B目的的一種方法。
It is waterproof cement mortar or cement mortar mixed with additives waterproof plaster of buildings to achieve a method of impermeability purposes.
4、地下工程的卷材防水層應(yīng)選用高聚物改性瀝青類或合成高分子類防水卷材。
Underground engineering waterproofing membrane should use polymer modified asphalt or synthetic polymer-based waterproofing membrane.
5、涂膜防水。此法價(jià)格低廉、施工方便。
This method is inexpensive and easy construction.
6、防水混凝土結(jié)構(gòu)防水。這是采用提高混凝土密實(shí)性的辦法，提高結(jié)構(gòu)混凝土的抗?jié)B性，還可滿足一定的耐凍融和耐侵蝕的要求。
This is the use of concrete to improve compactness approaches to improve the impermeability of the concrete structure, but also to meet certain requirements for resistance to freezing and thawing and erosion resistance.
7、排水減壓法。排水減壓法是在建筑物底下做出盲溝，創(chuàng)造自流排水的條件，當(dāng)無自流條件時(shí)，可通過盲溝將水引入集水井中，再用水泵抽排引走，減少水對地下工程的滲壓，起到防水作用。
Decompression method is to make a blind drainage ditch beneath the building, creating gravity drainage conditions, when there is no gravity conditions, can be introduced by the blind ditch water collection wells, then pump pumping lead away, reducing water underground engineering the osmotic pressure, played the role of water.
