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 second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements。s solemn mitment. criterion of a clean and honest administration consists of 4 parts, 18, more than 3600 words. After the revision of the code , a total of eight, 281 words, including lead, specification and Party member cadre clean fingered selfdiscipline norms, etc. Part 3 members lowcost clean and selfdiscipline, the main contents can be summarized as four must eight code. Lead part, reiterated on ideal and faith, fundamental purpose, the fine traditions and work style, noble sentiments, such as four must the principle of requirements, strong tone of selfdiscipline, The higher request for 6 and supervised tenet, the foothold in permanent Bao the party39。 at the same time, to investigate violations of Party members and even criminal behavior of Party discipline and responsibility, Regulations distinguish five different conditions, with special provisions were made provisions, so as to realize the connection of Party discipline and state law. 4, reflect Wind building and anticorruption struggle of the latest achievements. rule the party39。s basic theory, basic line, basic program and basic experience, the basic requirement of behavior made prescribed punishment, increase the cliques, against the organization such as violation of the provisions, to ensure that the central government decrees and the Party of centralized and unified. 3, adhere to strict discipline in the law and discipline In front, Ji separated. Revised Regulations adhere to the problem oriented, do Ji separated. Any national law existing content, will not repeat the provisions, the total removal of 79 and criminal law, repeat the content of the public security management punishment law, and other laws and regulations. In the general reiterated that party organizations and Party members must conscientiously accept the party39。s ideals and beliefs, excellent traditional style. The revised the code closely linked to the selfdiscipline, insisting on the positive initiative, for all members, highlight the vital few, emphasized selfdiscipline, focusing on the morality, and the majority of Party members and the ideological and moral standards. The revised Ji method separately, Ji, Ji Yan to Method, as a negative list, emphasizing the heteronomy, focusing on vertical gauge. Is this one high and one low, a positive reaction, the strict party discipline and practice results transformation for the integration of the whole party to observe moral and discipline requirements, for the majority of Party members and cadres provides benchmarking and ruler. Third, insist on to. In view of the problems existing in the party at the present stage, the main problems of Party members and cadres in the aspect of selfdiscipline and abide by the discipline to make clearly defined, especially 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。 施工現(xiàn)場(chǎng)材料機(jī)具管理： 施工機(jī)具和構(gòu)件材料按平面布置要分類存放整齊，并設(shè)標(biāo)志牌。（1） 施工現(xiàn)場(chǎng)材料堆放整齊。（3） 樹(shù)立“安全第一，預(yù)防為主”的指導(dǎo)思想，對(duì)職工進(jìn)行安全教育，認(rèn)真學(xué)習(xí)安全操作規(guī)程。，發(fā)現(xiàn)問(wèn)題及時(shí)解決，嚴(yán)禁相互扯皮，推卸責(zé)任造成工程事故或經(jīng)濟(jì)損失。 質(zhì)量保證措施： 為確保工程質(zhì)量，在整個(gè)施工全過(guò)程中，嚴(yán)格執(zhí)行質(zhì)量保證體系，以項(xiàng)目法施工為核心，對(duì)影響工程質(zhì)量的各要素進(jìn)行嚴(yán)格控制，確保工程質(zhì)量和進(jìn)度。 設(shè)立完善的組織管理機(jī)構(gòu)，選配精干、施工經(jīng)驗(yàn)豐富、工作踏實(shí)的施工技術(shù)管理人員，認(rèn)真負(fù)責(zé)搞好現(xiàn)場(chǎng)管理工作，責(zé)任明確，分工仔細(xì)。（8）棄土外運(yùn)：泥水通過(guò)泥漿池隔離倉(cāng)處理后沉淀后棄土。當(dāng)某一項(xiàng)工程確定后，可以從理論上對(duì)沉降進(jìn)行預(yù)測(cè)。（2）合理選擇工具管形式及施工方法：根據(jù)地質(zhì)和環(huán)境資料，合理選擇工具管形式及施工方法。（7）頂管開(kāi)始出洞的方向尤其重要。（7）承插時(shí)外力必須均勻，橡膠圈不移位，不反轉(zhuǎn)，不露出管外，否則應(yīng)拔出重插。（2）頂進(jìn)前應(yīng)對(duì)砼管成品，鋼套環(huán)，橡膠環(huán)，橡膠密封圈和軟木襯材料從尺寸、規(guī)格、性能、數(shù)量等均作詳細(xì)檢查，必須符合標(biāo)準(zhǔn)設(shè)計(jì)圖的要求。3）安裝頂鐵應(yīng)平順無(wú)歪斜扭現(xiàn)象，每次收回活塞加放頂鐵時(shí)，應(yīng)換用可能安放的最長(zhǎng)頂鐵，使連接的頂鐵數(shù)目為最少。頂進(jìn)頂進(jìn)利用千斤頂出鎬在后背不動(dòng)的情況下將被頂進(jìn)管子推向前進(jìn)，其操作過(guò)程如下：（1）安裝好頂鐵并擠牢，管前端已入土一定長(zhǎng)度后，啟動(dòng)油泵，千斤頂過(guò)油，活塞伸出一個(gè)工作行程，將管子推向一定距離。（8）在頂管施工地，要做好壓漿量、點(diǎn)的記錄，以確保壓漿到位，以降低管外壁擦阻力，提高頂管質(zhì)量，地面沿線有專人監(jiān)視，防止所壓漿打穿地層造成漿套損壞。（2）在管壁內(nèi)預(yù)埋壓漿孔，壓漿孔的位置要有利于漿液形成環(huán)狀。（6）激光經(jīng)緯儀測(cè)量架固定，不能與設(shè)備相連，必須與井單獨(dú)相連，以保證其它設(shè)備因頂力反作用而移位時(shí)，不影響到測(cè)量精度。軌道下排架固定時(shí)，除需與井底相連外，橫梁和豎梁加長(zhǎng)后撐于井壁，保證其固定牢靠。洞口止水圈由于沉井下沉過(guò)程中有誤差，所以在洞口止水圈安裝時(shí)應(yīng)把橡膠圈的中心與管道的設(shè)計(jì)中心一致，不使管道中心出現(xiàn)偏差。沉井封底沉井下沉至設(shè)計(jì)標(biāo)高，經(jīng)過(guò)觀測(cè)在8h內(nèi)累計(jì)下沉量不大于10mm或沉降率在允許范圍內(nèi)時(shí)，沉井下沉已經(jīng)穩(wěn)定時(shí)，既可進(jìn)行沉井封底。下沉挖土方法挖土必須對(duì)稱、均勻進(jìn)行，使沉井均勻下沉。真空度是判斷井點(diǎn)系統(tǒng)良好與否的尺度，應(yīng)經(jīng)常觀測(cè)。 （1）、施工工藝：放線定位→鋪設(shè)總管→沖孔→安裝井點(diǎn)管，填砂礫料，上部填粘土密封→用彎聯(lián)管將井點(diǎn)與總管接通→安裝抽水設(shè)備與總管連通→安裝集水箱和排水箱→開(kāi)動(dòng)真空泵排氣，再開(kāi)動(dòng)離心水泵抽水→測(cè)量觀測(cè)井中地下水位變化（隨挖土深度檢查觀測(cè)）。每抽出一根墊木后，應(yīng)立即用砂將空隙填實(shí)，同時(shí)在刃腳內(nèi)外側(cè)應(yīng)填筑成小土堤，并分層夯實(shí)。2）、當(dāng)混凝土強(qiáng)度達(dá)90％后，方可拆除刃腳斜面的支撐與模板。施工縫的表面應(yīng)與井壁相垂直，以防縱軸線方向產(chǎn)生錯(cuò)動(dòng)的剪力。為防止出現(xiàn)離析現(xiàn)象，砼澆筑時(shí)澆筑的自由高度不應(yīng)大于2m，砼澆筑時(shí)應(yīng)對(duì)稱平衡進(jìn)行，采用分層平鋪法，分層厚度控制在30cm左右，采用插入式振動(dòng)器，振搗時(shí)防止漏振和過(guò)振現(xiàn)象，以確保砼的質(zhì)量。鋼筋綁扎在內(nèi)模支立完畢，外模尚未扣合時(shí)進(jìn)行。井壁采用組合木模板，與混凝土接觸面先進(jìn)行刨光，與刃腳接觸的空隙要塞嚴(yán)防止漏漿。粗砂墊層分兩次攤鋪，然后人工初步平整，再采用蛙式打夯機(jī)依次夯打3～4遍，此時(shí)粗砂墊層密實(shí)度約為中密達(dá)到承載力。（2）對(duì)工作井、接收井的施工現(xiàn)場(chǎng)做好圍蔽。嚴(yán)格執(zhí)行各項(xiàng)施工保證措施，確保工程質(zhì)量。測(cè)量放樣及復(fù)核根據(jù)提供的測(cè)量基準(zhǔn)點(diǎn)，按設(shè)計(jì)圖紙要求進(jìn)行工作井及接收井的放樣工作，并放出頂管起點(diǎn)及終點(diǎn)的位置及頂進(jìn)的高程，在工作井正前方墻體頂部及底部、工作井后靠背中部頂部、接收井地面用鋼筋及油漆作好測(cè)量控制點(diǎn)的標(biāo)志。沿沉井刃腳圓弧部分對(duì)準(zhǔn)圓心鋪設(shè)。第一沉井筒壁應(yīng)按設(shè)計(jì)尺寸周邊1015mm，第二節(jié)相應(yīng)縮小一些，以減少下沉摩阻力，不能直接支撐到地面，以免沉井因加重而自動(dòng)下沉造成新澆筑的混凝土發(fā)生裂紋。（5）、澆筑混凝土分兩次澆筑，一次下沉的方法進(jìn)行。5）現(xiàn)場(chǎng)應(yīng)及時(shí)測(cè)定砼坍落度，每次澆砼根據(jù)規(guī)范做好抗?jié)B、抗壓的試驗(yàn)工作。8）砼澆注完畢后，須覆蓋草包，澆水養(yǎng)護(hù)。4）拆模后，下沉抽墊木前，仍應(yīng)將刃腳下回填密實(shí)，以防止不均勻沉陷，保證正位下沉，這對(duì)后期下沉的過(guò)程非常重要。當(dāng)繼續(xù)抽墊時(shí)，下沉量逐步加大，回填工作也逐漸困難，甚至出現(xiàn)下沉很快來(lái)不及回填的現(xiàn)象，致使墊木壓壞或壓斷?！谜惩撂顚?shí)，以防止漏氣。井點(diǎn)管淤塞，可通過(guò)聽(tīng)管內(nèi)水流聲，手扶管壁感到振動(dòng)，如井點(diǎn)管淤塞過(guò)多，影響降水效果時(shí)，應(yīng)逐個(gè)用高壓水反沖洗井點(diǎn)管或拔出重新埋設(shè)。當(dāng)沉井下沉很少或不下沉?xí)r，并繼續(xù)按圖向四周均勻掏挖，使沉井平穩(wěn)下沉。，達(dá)到50%設(shè)計(jì)強(qiáng)度后，綁扎鋼筋，兩端伸入刃腳或凹槽內(nèi)，澆筑上層底板混凝土。泥水平衡機(jī)施工簡(jiǎn)介本工程采用的泥水平衡機(jī)頭，頭部有1個(gè)切土刀盤，后面有偏心旋轉(zhuǎn)的破碎槽，可破碎100mm以下的塊石，后部為
