濟(jì)南專業(yè)防水http://www.ochf.cn/談到防水混凝土工程質(zhì)量除精心設(shè)計(jì)、合理選材外，關(guān)鍵還要保證施工質(zhì)量。對(duì)施工中的各主要環(huán)節(jié)，如混凝土的攪拌、運(yùn)輸、澆筑振搗、養(yǎng)護(hù)等，均應(yīng)嚴(yán)格遵循施工及驗(yàn)收規(guī)范和操作規(guī)程的規(guī)定進(jìn)行施工，以保證防水混凝土工程的質(zhì)量。混凝土工程的模板應(yīng)平整且拼縫嚴(yán)密不漏漿并有足夠的強(qiáng)度和剛度，吸水率要小。一般不宜用螺栓或鐵絲貫穿混凝土墻固定模板，當(dāng)墻高需要用螺栓貫穿混凝土墻模板時(shí)，應(yīng)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.
　　
濟(jì)南專業(yè)防水介紹地下混凝土表面需要防水有以下幾個(gè)原因。最主要的一點(diǎn)是為了防止水分滲透到建筑物內(nèi)。另外，做防水也可以保護(hù)建筑結(jié)構(gòu)破壞或預(yù)埋鋼筋腐蝕。混凝土是一種多孔材料，水分可通過(guò)靜水壓、水汽梯度或毛細(xì)作用滲透到其內(nèi)部。水也能進(jìn)入裂縫、結(jié)構(gòu)缺陷或設(shè)計(jì)施工不當(dāng)?shù)倪B接處，防水也可以因施工現(xiàn)場(chǎng)內(nèi)外化學(xué)物質(zhì)引起的混凝土品質(zhì)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.
　　
濟(jì)南專業(yè)防水提醒混凝土結(jié)構(gòu)需要防水以防止水分滲入設(shè)施內(nèi)，保護(hù)混凝土結(jié)構(gòu)本身和預(yù)埋的鋼筋。一個(gè)明顯的問(wèn)題是混凝土在硬化后會(huì)開(kāi)裂，裂縫使水分容易滲入。硬化前，混凝土可能由于結(jié)構(gòu)位移、塑性變形、干縮或早期霜凍而開(kāi)裂。硬化后，混凝土則可能由于沉降、震動(dòng)、徐變、超載或因地基土移動(dòng)造成的傾斜而開(kāi)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.
　　
濟(jì)南專業(yè)防水http://www.ochf.cn/建議除了混凝土本身是多孔性材料之外，混凝土結(jié)構(gòu)還有許多極易滲水的部位，包括所有混凝土接縫處、控制縫和膨脹縫。滲水的口子也可能發(fā)生在拉桿孔、穿孔部位和結(jié)構(gòu)連接處，混凝土內(nèi)部排水管也是極易滲透的地方。
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.
