I. surface

　　現(xiàn)象：灌漿料部分外表現(xiàn)象呈現(xiàn)缺漿和許多小凹坑、麻點(diǎn)，構(gòu)成粗糙面，但無鋼筋外露現(xiàn)象。

　　Phenomenon: the appearance of grouting material part shows lack of grout and many small pits and pockmarks, forming a rough surface, but no reinforcement exposed.

　　產(chǎn)生的緣由

　　Why it came into being

　　1模板拼縫不嚴(yán)，部分漏漿；

　　1. The joint of formwork is not tight, and part of formwork is leaked;

　　2模板隔離劑涂刷不勻，或部分漏刷或失效，灌漿料外表與模板粘結(jié)形成麻面；

　　2. The formwork isolating agent is not evenly applied, or part of it is missing or invalid, and the surface of grouting material is bonded with the formwork to form a pitted surface;

　　3模板外表粗糙或粘附水泥漿渣等雜物未清算潔凈，拆模時(shí)灌漿料外表被毀壞；

　　3. The surface of the formwork is rough or the sundries such as cement slurry slag are not cleared and cleaned, and the surface of the grouting material is damaged when the formwork is removed;

　　4模板未澆水潮濕或潮濕不夠，構(gòu)件外表灌漿料的水分被吸去，使灌漿料失水過多呈現(xiàn)麻面；

　　4. The formwork is not watered wet or not wet enough, and the moisture of the grouting material on the surface of the component is absorbed, which makes the grouting material lose too much water and present a pitted surface;

　　5灌漿料振搗不實(shí)，氣泡未排出，停在模板外表現(xiàn)象構(gòu)成麻點(diǎn)。

　　5. The grouting material is not vibrated properly, the bubbles are not discharged, and it stops on the surface of the formwork to form pockmarks.

　　防治措施

　　Preventive measures

　　1模板外表清算潔凈，不得粘有干硬水泥砂漿等雜物；澆灌灌漿料前，模板應(yīng)澆水充沛潮濕；模板縫隙，應(yīng)用油氈紙、膩?zhàn)拥榷聡?yán)；模板隔離劑應(yīng)選用長效的，涂刷平均，不得漏刷；灌漿料應(yīng)分層平均振搗密實(shí)，至掃除氣泡為止；

　　1. The surface of the formwork shall be clean and free of dry and hard cement mortar and other sundries; before grouting, the formwork shall be watered with sufficient moisture; the gaps of the formwork shall be blocked with felt paper and putty; the long-term formwork isolating agent shall be selected and brushed evenly without missing; the grouting material shall be vibrated and compacted evenly by layers until the bubbles are removed;

　　2. 外表作粉刷的，可不處置，外表現(xiàn)象無粉刷，應(yīng)在麻面部位澆水充沛潮濕后，可用1：2或1：2.5水泥砂漿，將麻面抹平壓光。

　　2. If the surface is painted, it is not necessary to deal with it. If there is no painting on the surface, the hemp surface can be leveled and polished with 1:2 or 1:2.5 cement mortar after the hemp surface is fully watered and wet.

　　二、外表不平整

　　II. Uneven appearance

　　現(xiàn)象：灌漿料外表凹凸不平，或板厚薄不一，外表不平。

　　Phenomenon: the surface of grouting material is uneven, or the thickness of the board is different, and the surface is uneven.

　　產(chǎn)生的緣由

　　Why it came into being

　　1.灌漿料澆筑后，外表僅用鐵鍬拍子，未用抹子找平壓光，形成外表粗糙不平；

　　1. After the grouting material is poured, the surface is only leveled with spade and troweled without trowel, resulting in rough and uneven surface;

　　2.模板未支撐在堅(jiān)硬土層上，或支承面缺乏，或支撐松動、泡水，致使新澆灌灌漿料早期養(yǎng)護(hù)時(shí)發(fā)作不平均下沉；

　　2. The formwork is not supported on the hard soil layer, or the bearing surface is lack, or the support is loose and water is soaked, which causes the uneven sinking of the new grouting material during the early maintenance;

　　3.灌漿料未到達(dá)一定強(qiáng)度時(shí)，上人操作或運(yùn)料，使外表現(xiàn)象呈現(xiàn)凹陷不平或印痕。

　　3. When the grouting material does not reach a certain strength, the operator shall operate or transport the material to make the appearance appear concave, uneven or imprinted.

　　防治措施

　　Preventive measures

　　嚴(yán)厲按施工標(biāo)準(zhǔn)操作，澆筑灌漿料后，應(yīng)依據(jù)程度控制標(biāo)志或彈線用勢抹子找平、壓光，終凝后澆水養(yǎng)護(hù)；模板應(yīng)有足夠強(qiáng)度、剛度和穩(wěn)定性應(yīng)支在堅(jiān)實(shí)地基上，有足夠的支撐面積，并避免浸水，以保證不發(fā)作下沉；在澆筑灌漿料時(shí)，增強(qiáng)檢查，灌漿料強(qiáng)度到達(dá)1.2N/㎜2以上，方可在已澆構(gòu)造上走動。

　　Operate in strict accordance with the construction standards. After grouting materials are poured, level and polish with a potential trowel according to the degree of control marks or snapping lines, and water for maintenance after final setting. The formwork shall have enough strength, rigidity and stability, which shall be supported on a solid foundation, with enough supporting area, and avoid flooding to ensure no sinking. When grouting materials are poured, strengthen the inspection, and the strength of grouting materials shall reach 1.2N /Only when it is more than 2 mm can it walk on the poured structure.
