Leaders as members of the Communist Party of China clean politics certain criteria (Trial) based on revised, the promulgation and implementation of January 2010, to strengthen the construction of the contingent of leading cadres play an important role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too plicated, eight prohibition, 52 are not allowed to hard to remember, and also difficult to put into practice。s leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the code and rule , reflects the party39。 the fourth part on how to grasp the implementation of the two regulations of the party. code and Regulations revised the necessity and revised history of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines and Chinese Communist Party discipline and Punishment Regulations column 1 by 2015 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation。 the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party。壓力灌漿封縫的施工工藝流程如下圖:裂縫檢查裂縫基面清理注入座安裝膠材料拌和裂縫封閉嚴格的灌注順序及注膠控制注入孔及封縫段的表面處理壓力灌漿封縫的工藝流程圖 遂資眉高速公路遂資至資陽段項目TJ17工區(qū)橋面鋪裝混凝土表面龜裂處理方案編制:審核:審批:編制單位:重慶交通建設(shè)(集團)有限責任公司四川遂資眉高速公路TJ1項目部第七工區(qū)編制日期:二O一三年四月目錄一、工程概況…………………………………………………………….1二、編制依據(jù)…………………………………………………………….1三、原因分析……………………………………………………………1四、處置方案……………………………………………………………2五、施工工藝…………………………………………………………….2 54(英文版 ) Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementation of prehensive strictly strategic plan, implementation in accordance with the rules and discipline to manage the party, strengthen innerparty supervision of major initiatives. The two regulations supporting each other, the code adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard。5)用丙酮清洗注入工具。4)注入灌注膠 待封縫膠達到強度后,將注入器安裝在注入座上,用適度壓力注膠。⑧ 灌縫施工在產(chǎn)品規(guī)定施工操作溫度下進行;⑨ 灌膠順序,豎縫必須自下而上,平縫可自一端向另一端逐一進行;⑩ 縫隙全部注滿后按材料要求進行養(yǎng)護,待灌縫膠液固化后,拆除灌漿嘴,并對混凝土表面進行修整。試漏前沿裂縫涂一層肥皂水,從灌膠嘴壓入壓縮空氣,凡漏氣處,修補封縫至不漏為止;⑦ 灌縫用膠必須按照所選用產(chǎn)品確定的配合比進行拌和,準確稱量各組成材料并均勻攪拌。2)粘結(jié)注入座和密封裂縫④ 調(diào)制好封口膠,攪拌均勻,用抹刀將少許膠刮在注入座底面的四邊,將注入座固定在混凝土上;⑤ 注入座的布置應掌握以下原則:沿縫的走向,每米約布置3個,裂縫分岔處的交叉點應設(shè)注入座,選混凝土表面平整處設(shè)置,避開剝落部位,對貫通縫,可在一側(cè)布置注入座,另一側(cè)完全封閉,縫寬較大且內(nèi)部通暢時,可以按每米2個的密度來布置;⑥ 用封口膠將裂縫密封,與注入座銜接的地方要特別注意。用密封膠對漏氣的區(qū)域進行封閉,待達到強度再氣檢,如此反復直至不漏氣為止。然后采用壓力灌注封閉 按縫寬劃分裂縫的處理方法裂縫寬度處理方法<表面涂刷封閉≥壓力灌注封閉≥壓力灌注封閉⑴表面涂刷封縫法施工細則:封縫用小鏟刀將封縫膠刮抹到裂縫上,厚度1mm左右,寬度20~30mm,抹膠時應防止產(chǎn)生小孔和氣泡,要刮平整,保證封閉嚴密可靠。對于所有可見裂縫,均應進行處理。根據(jù)《公路橋梁加固設(shè)計規(guī)范》的規(guī)定,以及加固措施和環(huán)境的現(xiàn)狀,裂縫寬度在限制范圍內(nèi)(< mm)時可進行表面封閉處理,采用涂刷專用環(huán)氧樹脂膠或水泥漿封閉;裂縫寬度大于限制范圍內(nèi)(≥ mm)時,采用壓力灌漿法灌注環(huán)氧樹脂膠處理。 五、施工工藝對混凝土表面所有可見裂縫進行封閉處理。擬采取以下處置方案:對所有可見裂縫進行封閉處理。過早通車因素為保證路面及交安單位交通轉(zhuǎn)換要求,混凝土澆筑后未達到設(shè)計強度即開放交通,造成混凝土表面出現(xiàn)開裂。特別是天氣溫度高養(yǎng)護濕度不足。 收縮裂紋由于混凝土內(nèi)外水分蒸發(fā)程度不同而導致變形不同的結(jié)果:混凝土受外部條件的影響,表面水分損失過快,變形較大,內(nèi)部濕度變化較小,變形較小,較大的表面干縮變形受到混凝土內(nèi)部約束,產(chǎn)生較大拉應力而產(chǎn)生裂縫。出現(xiàn)混凝土表面龜裂的梁體生產(chǎn)時間集中在春季(2013年4月),混凝土內(nèi)外溫差大造成混凝土表面發(fā)生龜裂,產(chǎn)生裂紋。出現(xiàn)表面裂紋的橋面鋪裝混凝土澆筑時間集中在2013年4月份。上部結(jié)構(gòu)為預制T梁,箱梁跨徑30米,采用C40混凝土。一、 工程概況文家溝大橋位于遂資眉高速公路遂寧至資陽段,=(防撞護欄)+(橋面凈寬)+(中央分隔帶)+(橋面凈寬)+(防撞護欄)。設(shè)計荷載為公路1級。文家溝大橋左幅橋面鋪裝混凝土頂面存在縱向和橫向裂紋,經(jīng)現(xiàn)場核實,~,裂紋位置深度主要為1cm~3cm。二、編制依據(jù) 《遂資高速公路TJ17工區(qū)設(shè)計圖》 《公路橋梁加固施工技術(shù)規(guī)范》JTG/TJ232008 《混凝土結(jié)構(gòu)加固設(shè)計規(guī)范》(GB503672006)《公路工程質(zhì)量檢驗評定標準》JTGF80/12004《公路橋梁施工技術(shù)規(guī)范》JTG/T F202011 三、原因分析經(jīng)核實橋面鋪裝混凝土當時生產(chǎn)情況和混凝土表面龜裂情況,總結(jié)為引起混凝土表面發(fā)生龜裂的原因主要為變形引起的裂紋;溫度變化、收縮及養(yǎng)護因素。橋面鋪裝混凝土澆筑后,在硬化過程中,水泥水化產(chǎn)生大量的水化熱聚積在混凝土內(nèi)部而不易散發(fā),導致內(nèi)部溫度急劇上升,而混凝土表面散熱較快,使得混凝土結(jié)構(gòu)內(nèi)外出現(xiàn)較大的溫差,這些溫差造成混凝土表面就會產(chǎn)生裂縫。 養(yǎng)護因素橋面鋪裝混凝土施工期間采用土工布養(yǎng)護,但養(yǎng)護效果不好。從而引起了梁體混凝土表面龜裂。四、處置方案經(jīng)現(xiàn)場核實橋面鋪裝混凝土表面裂紋主要為淺層表面裂紋,不會影響到橋面鋪裝結(jié)構(gòu)安全及使用效果。對裂縫寬度≥;對于裂縫寬度<,涂刷環(huán)氧樹脂膠或水泥漿封閉。裂縫按其寬度分別采用表面涂刷封閉和灌注封閉兩種方法進行處理。因為現(xiàn)場測量裂縫寬度時可能存在不準確的情況,為了使超過規(guī)范規(guī)定的裂縫盡可能得到維修,并提高橋梁整體維修效果。沿裂縫進行剔鑿,根據(jù)開裂情況鑿出寬、深各15~20mm的V型槽。 裂縫封閉后應進行壓氣試漏,待封縫膠有一定強度時,沿裂縫涂一層肥皂水,從注膠底座通入壓縮空氣,若有氣泡冒出則說明該處漏氣,做好標記。 ⑵壓力灌漿法施工細則:1)裂縫表面處理① 用鋼絲刷沿裂縫走向清理寬約5cm范圍的混凝土表面,使混凝土表面保持清潔;② 用錘子和鋼釬鑿除兩側(cè)疏松的混凝土塊和砂粒,露出堅實的混凝土面;③ 用略潮濕的抹布清除表面的浮塵,并徹底晾干,用丙酮清除表面的油污,如縫內(nèi)潮濕,要等其充分干燥,必要時可用噴燈烘干。灌縫前,逐一加壓檢查灌膠嘴的連通和裂縫封閉效果即試漏,試漏需待封縫膠有一定強度時進行。灌縫膠配置好后,盡快將其注入到裂縫中,并在該產(chǎn)品規(guī)定的適用期內(nèi)使用完畢。3)封口膠的固化①密封完成后,讓封口膠自然固化,注意固化過程中防止其接觸水;②固化時間:約12小時(氣溫20℃時)、約6小時(氣溫30℃時)。如注入器膨脹后很快收縮,說明縫內(nèi)空間大,還需補灌;當橡膠管膨脹充滿限制時停止注入。6)注入材料的固化用手直接觸摸檢查材料的硬化強度,硬化后敲掉注入座。 rule around the party discipline, disciplinary ruler requirements, listed as negative list, focusing on vertical gauge, draw the party organizations and Party members do not touch the bottom line . Here, the main from four square face two party rules of interpretation: the first part introduces two party Revised regulations the necessity and the revision process。 the third part introduces two party regulations modified the main changes and needs to grasp several key problems。 follow the correct direction, grasp the limited goals, adhere to the party39。s 18 and the eighth session of the third, the spirit of the fourth plenary session, reflecting the experience of studying and implementing the General Secretary Xi Jinping series of important speech, reflects the party39。 the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements。 the fourth is to clean the theme is not prominent, not for the existing problems, and is narrow, only needle of countylevel leading cadres above. rule is in 1997 Chinese Communist Party disciplinary cases (Trial) based on revision, in December 2003 the promulgation and implementation, to strengthen the construction of
