在堤堰防渗中灌浆技能应遵从的准则分析中英文Analysis on the dam anti-seepage grouting skills in English should follow the principle of 在堤堰防渗工程中，高压喷发灌浆技能与惯例砼防渗墙比拟，可不一样程度地下降工程造价，具有开挖量小，施工便利，占地少，对接近建筑物影响小等特色。此项技能很大程度地进步了江、河、湖、库、渠的堤堰防渗抗灾才能，减轻防洪压力，对包管公民生命财产安全以及社会经济发展将起到活跃的效果，其社会效益是十分显着的。 On the dam anti-seepage engineering skills and practices, high pressure grouting concrete cutoff wall is eruptive, different degree reduced engineering cost, with less excavation, construction is convenient, less land occupation, little effect on close to the building characteristics. This technology greatly improved the dikes seepage River, river, lake, reservoir, canal anti-disaster ability, reduce the pressure of flood control, to ensure the safety of the lives and property of citizens and the social and economic development will play an active effect, its social benefits are very significant.灌浆治漏加固技能简介 Grout for reinforcement of skills.1坝体、坝基帷幕灌浆；首要充填缝隙和缝隙，防渗裁漏，经过灌浆加固，构成防渗体。此办法适用于浆砌石重力坝。 The 1 dam, dam foundation curtain grouting; primary filling gap and gap, seepage cut leakage, after grouting, anti-seepage body. This method is applicable to the masonry gravity dam.2坝上游面固结灌浆；阻塞缝隙和缝隙，加固补强坝体和进步防渗功能，以进一步进步坝体的承载才能和完整性。 2 dams upstream consolidation grouting; clog the gap and gap, strengthening the body and progress of seepage control function, in order to bearing capacity and integrity of the further progress of dam.3坝下流面追寻固结灌浆；在下流坝面有漏水或溶蚀物出逸的当地，构成水平孔或斜孔，埋注浆管进行灌浆，以阻塞漏水通道和坝体空泛、裂缝，加固坝体，添加坝面稳定性和抗冲刷才能。这种反向灌浆工艺，十分合适拱坝和支墩坝工程，对重力坝工程只要搞清扬压力并设排水孔也可选用。选用这种办法时最棒是坝前无水。 The 3 dam downstream surface after consolidation grouting; under the dam surface water leakage or corrosive escape local, constitute the horizontal holes or inclined hole grouting, pipe grouting, to block the water leakage channel and dam vague, crack, reinforcement on the dam, add the stability of dam surface and the anti-erosion ability. This kind of reverse grouting technology, is very suitable for arch dam and buttress dam project on the dam, as long as I clear pressure and drainage holes can also be selected. Use this option when the stick is anhydrous before dam.4坝面从头剔勾缝；剔缝后，用高标号水泥砂浆、干硬性预缩水泥砂浆或用防水资料制造高标号水泥砂浆勾缝，进步坝面防渗漏才能及坝体稳定性、整体性和抗冻融、抗风波淘刷才能。此办法即“前堵、中截、后追寻”灌浆治漏加固法。 The 4 dam from the tick tick pointing; joint, use dry shrinkage of cement mortar or manufacturing high-grade cement mortar pointing with waterproof material of high grade cement mortar, the dam seepage prevention ability, progress and stability of the dam, the integrity and the frost resistance, resistance to disturbance scour. This approach is " blocking, cutting, in pursuit of grout for reinforcement method ".灌浆治漏加固技能布孔和造孔应遵从的准则 Grout for reinforcement of skills Hezao hole hole should comply with the criterion1帷幕灌浆布孔，在漏水坝段沿坝顶中心线，以孔距3m、孔径50mm或75mm为宜，或依据实验断定孔距。孔深钻至漏水部位以下1m2m，如触摸带或基岩漏水，钻孔可钻至不透水基岩以下lm2m。造孔可一次性造孔，也可分序造孔，破碎地带上下分段造孔、分段海浆，一同在浆体凝结5-7天后，再持续向下钻孔，以避免卡钻、埋钻事端发作。坝体与基岩触摸部位和坝基灌浆，也可采纳在上游坝脚打斜孔或笔直孔灌浆堵漏，但造孔前应先清基，在坝脚浇筑03m一05m厚混凝土，待凝结后再打孔。笔直或倾角小于5。的帷幕灌浆孔，其孔向的偏差值不得大于规定值。 1 curtain grouting hole, the water leakage along the crest of the center line, the hole distance 3M, aperture 50mm or 75mm is appropriate, or according to the experiment concluded that the pitch of holes. Deep hole drilling to water leakage site 1m - 2m, such as touch or bedrock water leakage, holes can be drilled to impervious bedrock below LM - 2m. Pore disposable pore, can be divided into a sequence of pore, fracture zone under the subsection pore, segmented sea slurry, slurry condensation together in 5-7 days, and then continued downward drilling, to avoid sticking, drill burying somethin attack. Dam and bedrock touch location and dam foundation grouting, also can be adopted in the upstream toe oblique hole or a straight hole grouting leakage stoppage, but pore before clearing, foot placement in 0.3m 0.5m thick concrete, to be condensed to drill. Straight or angle of less than 5. The curtain grouting hole, the hole to the deviation shall not exceed the specified value.2坝上游固结灌浆布孔；在漏水部位呈“梅花”型，钻孔距离和排距lm3m为宜，依据漏水状况断定，钻孔方位选在砌石“了”缝中；在裂缝部位，可沿裂缝每lm布设一孔。孔径为42mm，孔深07m15m，依据坝体实际状况断定。 2 dams upstream consolidation grouting hole; a " plum " in water leakage location, hole spacing and row spacing of LM - 3M is appropriate, based on the condition that water leakage, drilling direction in stone " of the " joint; in the cracks, cracks along each LM to deploy a hole. Aperture is 42mm, hole depth of 0.7m - 1.5m, according to the actual situation of dam that.3坝下流面追寻固结淄浆布孔；在裂缝部位沿缝隙每1m布一孔；在其它渗水部位，依照“梅花”型布孔，排距和孔距2m3m为宜，布孔方位在?“T”缝中，也可适当加布满孔。孔深和孔径同坝上游面。 The 3 dam downstream surface after consolidation black slurry hole; in the cracks along the slot per 1m cloth hole; in other seepage sites, in accordance with the " plum blossom " type hole, row spacing and hole distance 2m - 3M is appropriate, the hole position in? " T " slot, can also be appropriate to add full of holes. Kong Shen and aperture with the upstream dam face.
