| 缺陷是指混凝土结构施工质量不符合规定要求的检验项或检验点。 Defects are the inspection items or inspection points that the construction quality of the concrete structure does not meet the requirements of the regulations. 现浇结构的外观质量不应有严重缺陷。对已出现的严重缺陷，应由施工单位提出技术处理方案，并经监理单位认可后进行处理；对裂缝、连接部位出现的严重缺陷及其他影响结构安全的严重缺陷，技术处理方案尚应经设计单位认可。对经处理的部位，应重新检查验收。 There should be no serious defects in the appearance quality of the cast-in-place structure. The serious defects have occurred, by the construction unit put forward the technical scheme, and the supervision units approved after treatment; serious defect serious defects on cracks, joints and other appear to affect the safety of the structure, the technical scheme should be approved by the design unit. The treated parts should be checked and checked again. 现浇结构的外观质量不应有一般缺陷。对已出现的一般缺陷，应由施工单位按技术处理方案进行处理，对经处理的部位应重新验收。 The appearance quality of the cast-in-place structure should not have general defects. The existing general defects should be treated by the construction unit according to the technical treatment plan, and the treated parts should be re accepted. 1、缺陷分类 1, defect classification 混凝土结构缺陷可分为尺寸偏差缺陷和外观缺陷。尺寸偏差缺陷和外观缺陷可分为一般缺陷和严重缺陷。混凝土结构尺寸偏差超出规范规定，但尺寸偏差对结构性能和使用功能未构成影响时，应属于一般缺陷；而尺寸偏差对结构性能和使用功能构成影响时，应属于严重缺陷。外观缺陷分类应符合下表的规定。 The defects of concrete structures can be divided into dimensional deviation and appearance defects. Size and appearance defects can be divided into general and serious defects. The size deviation of the concrete structure is beyond the specification, but when the size deviation does not affect the structure performance and service function, it should belong to the general defect. The size deviation should be a serious defect when it affects the structure performance and the use function. The classification of appearance defects should be in accordance with the provisions of the table below. 名称 Name 现象 phenomenon 严重缺陷 serious disadvantage 一般缺陷 General defects 露筋 Reinforcement 构件内钢筋未被混凝土包裹而外露 The steel bar in the component is not covered with concrete and is exposed 纵向受力钢筋有露筋 Longitudinal reinforced bar with ribs 其他钢筋有少量露筋 Other steel bars have a small amount of gluten 蜂窝 honeycomb 混凝土表面缺少水泥砂浆而形成石子外露 The lack of cement mortar on the surface of concrete to form a stone surface 构件主要受力部位有蜂窝 The main parts of the component are honeycomb 其他部位有少量蜂窝 A small number of honeycombs in other parts 孔洞 Void 混凝土中孔穴深度和长度均超过保护层厚度 Cavity length and depth of concrete are more than the thickness of the protective layer 构件主要受力部位有孔洞 There is a hole in the main part of the component. 其他部位有少量孔洞 There are small holes in the other parts 夹渣 Slag 混凝土中夹有杂物且深度超过保护层厚度 The concrete is covered with sundries and the depth exceeds the thickness of the protective layer 构件主要受力部位有夹渣 The main force part of the component is slags 其他部位有少量夹渣 There is a small amount of slag in other parts 疏松 Loose 混凝土中局部不密实 Locally non compacted concrete 构件主要受力部位有疏松 The main parts of the component are loose 其他部位有少量疏松 There is a small amount of looseness in other parts 裂缝 crack 缝隙从混凝土表面延伸至混凝土内部 The crevice extends from the concrete surface to the concrete interior 构件主要受力部位有影响结构性能或使用功能的裂缝 A crack in the main part of a component that affects structural performance or function. 其他部位有少量不影响结构性能或使用功能的裂缝 There are few cracks in other parts that do not affect structural performance or function. 连接部位缺陷 Joint defect 构件连接处混凝土有缺陷及连接钢筋、连接件松动 Concrete defects at the joint of the component and the loosening of connecting bars and connecting parts 连接部位有影响结构传力性能的缺陷 Defects that affect the force performance of the structure 连接部位有基本不影响结构传力性能的缺陷 There is a defect in the connection position that does not affect the force performance of the structure. 外形 appearance 缺陷 defect 缺棱掉角、棱角不直、翘曲不平、飞边凸肋等 Missing angle, straight angle, warping, flirting ribs, etc 清水混凝土构件有影响使用功能或装饰效果的外形缺陷 The shape defects of the concrete members have influence on the use function or the decorative effect 其他混凝土构件有不影响使用功能的外形缺陷 Other concrete components have defects that do not affect the use function. 外表 appearance 缺陷 defect 构件表面麻面、掉皮、起砂、玷污等 The component surface voids, peel, sand, and defiled 具有重要装饰效果的清水混凝土构件有外表缺陷 Clear water concrete members with important decorative effects have appearance defects 其他混凝土构件有不影响使用功能的外表缺陷 Other concrete components have external defects that do not affect the use of functions 施工过程中发现混凝土结构缺陷时，应认真分析缺陷产生的原因。对严重缺陷施工单位应制定专项修整方案，方案应经论证审批后再实施，不得擅自处理。 When the concrete structure is found in the construction process, the cause of the defect should be carefully analyzed. A special repair scheme should be formulated for the construction units with serious defects. The scheme should be carried out after examination and approval and shall not be handled without authorization. 2、外观一般缺陷处理 2, general appearance defect treatment 混凝土结构外观一般缺陷修整应符合下列规定： The general defects of the concrete structure should be repaired in accordance with the following provisions: （1）露筋、蜂窝、孔洞、夹渣、疏松、外表缺陷，应凿除胶结不牢固部分的混凝土，应清理表面，洒水湿润后应用1:2～1:2.5水泥砂浆抹平； (1) exposed tendons, honeycombs, holes, slag, loose and surface defects. We should dig out the concrete which is not cemented. We should clean up the surface. After watering and moistening, we use 1:2 ~ 1:2.5 cement mortar to smooth. （2）应封闭裂缝； (2) the cracks should be closed; （3）连接部位缺陷、外形缺陷可与面层装饰施工一并处理。 (3) the defects of the connecting parts and the defects of the shape can be handled with the decorative construction of the surface layer. 3、外观严重缺陷处理 3. Treatment of serious defects 混凝土结构外观严重缺陷修整应符合下列规定： The repair of the serious defects of the concrete structure should comply with the following provisions: （1）露筋、蜂窝、孔洞、夹渣、疏松、外表缺陷，应凿除胶结不牢固部分的混凝土至密实部位，清理表面，支设模板，洒水湿润，涂抹混凝土界面剂，应采用比原混凝土强度等级高一级的细石混凝土浇筑密实，养护时间不应少于7d； (1) reinforcement, honeycomb holes, slag inclusion, porosity, surface defect, loose concrete shall be chiseled in cement to compacting parts, parts of the surface cleaning, supporting form, water wet smear concrete interface agent should be used in fine stone concrete compacting concrete strength than the original high level, maintenance the time should not be less than 7d; （2）开裂缺陷修整应符合下列规定： (2) dehiscence defects should be repaired in accordance with the following provisions: 1）民用建筑的地下室、卫生间、屋面等接触水介质的构件，均应注浆封闭处理。民用建筑不接触水介质的构件，可采用注浆封闭、聚合物砂浆粉刷或其他表面封闭材料进行封闭； 1) the components of the basement, toilet and roofing of civil buildings should be treated with grouting. The members of civil buildings that do not contact with water medium can be closed by grouting sealing, polymer mortar or other surface sealing materials. 2）无腐蚀介质工业建筑的地下室、屋面、卫生间等接触水介质的构件以及有腐蚀介质的所有构件，均应注浆封闭处理。无腐蚀介质工业建筑不接触水介质的构件，可采用注浆封闭、聚合物砂浆粉刷或其他表面封闭材料进行封闭。 2) no corrosion medium, such as basement, roof, toilet and other components, and all members with corrosive medium should be treated by grouting. The components of non corrosive medium industrial buildings without contact with water medium can be closed by grouting sealing, polymer mortar brush or other surface sealing materials. （3）清水混凝土的外形和外表严重缺陷，宜在水泥砂浆或细石混凝土修补后用磨光机械磨平。 (3) serious defects in the shape and appearance of clear water concrete should be smoothed by grinding machine after cement mortar or fine stone concrete repair. 4、尺寸偏差缺陷处理 4, size deviation defect treatment 混凝土结构尺寸偏差一般缺陷，可结合装饰工程进行修整。混凝土结构尺寸偏差严重缺陷，应会同设计单位共同制定专项修整方案，结构修整后应重新检查验收。 The size deviation of the concrete structure is generally defective, and it can be repaired with the decoration project. The size deviation of the concrete structure is seriously defective, and the special repair plan should be worked out together with the design unit, and the structure should be rechecked and checked after the structure is trimmed. |
