济南专业防水http://www.tianyujian.com/谈到防水混凝土工程质量除精心设计、合理选材外，关键还要保证施工质量。对施工中的各主要环节，如混凝土的搅拌、运输、浇筑振捣、养护等，均应严格遵循施工及验收规范和操作规程的规定进行施工，以保证防水混凝土工程的质量。混凝土工程的模板应平整且拼缝严密不漏浆并有足够的强度和刚度，吸水率要小。一般不宜用螺栓或铁丝贯穿混凝土墙固定模板，当墙高需要用螺栓贯穿混凝土墙模板时，应采取止水措施。
Jinan professional waterproof waterproof concrete construction quality in addition to talk about well-designed,reasonable selection, the key also to ensure construction quality. The construction of the major components, such as concrete mixing, transport, pouring vibration, maintenance, etc., should strictly abide by the norms and rules of construction and acceptance requirements for construction, to ensure the quality waterproof concrete project. Formwork for concrete projects should be smooth and seam tight slurry does not leak and have sufficient strength and rigidity, the water absorption is smaller. Generally should not use bolts or wire through the concrete wall fixed template, when the wall height needed bolt through the concrete wall form, sealing measures should be taken.
济南专业防水介绍地下混凝土表面需要防水有以下几个原因。最主要的一点是为了防止水分渗透到建筑物内。另外，做防水也可以保护建筑结构破坏或预埋钢筋腐蚀。混凝土是一种多孔材料，水分可通过静水压、水汽梯度或毛细作用渗透到其内部。水也能进入裂缝、结构缺陷或设计施工不当的连接处，防水也可以因施工现场内外化学物质引起的混凝土品质下降。
Jinan professional waterproof underground concrete surface needs to introduce water for several reasons. The main point is to prevent the penetration of moisture into the building. In addition, it can also protect the building waterproof structural damage or corrosion of embedded steel. Concrete is a porous material, the moisture can penetrate into the interior through the hydrostatic pressure gradient, or capillary action of water vapor. Water can enter the cracks, structural defects or improper design and construction joints, concrete water quality can also be due to the construction site and outside the decline caused by chemical substances.
济南专业防水提醒混凝土结构需要防水以防止水分渗入设施内，保护混凝土结构本身和预埋的钢筋。一个明显的问题是混凝土在硬化后会开裂，裂缝使水分容易渗入。硬化前，混凝土可能由于结构位移、塑性变形、干缩或早期霜冻而开裂。硬化后，混凝土则可能由于沉降、震动、徐变、超载或因地基土移动造成的倾斜而开裂。
Jinan professional waterproof concrete structures need to remind waterproof to prevent moisture penetration within the facility, protect the concrete structure itself and the embedded steel. One obvious problem is that the concrete will
crack after hardening, cracks so that water easily penetrate. Before hardening, the concrete may be due to structural displacement, plastic deformation, shrinkage or early frost cracking. After hardening, the concrete may be due to subsidence, vibration, creep, overloading or tilt caused due to soil movement and cracking.
济南专业防水http://www.tianyujian.com/建议除了混凝土本身是多孔性材料之外，混凝土结构还有许多极易渗水的部位，包括所有混凝土接缝处、控制缝和膨胀缝。渗水的口子也可能发生在拉杆孔、穿孔部位和结构连接处，混凝土内部排水管也是极易渗透的地方。
Jinan professional waterproof concrete proposal in addition to outside the porous material itself, there are many highly seepage concrete structure of the site, including all concrete joints, control joints and expansion joints. Seepage hole may also occur in the rod hole, perforation site and structural connections, but also easy to penetrate inside the concrete drainage areas.
