方案概述综合考虑地下管线的改移断面尺寸、埋深及施工进度的因素，东方马城站范围内地下管线改移方案如下：1、排水管线全部废弃，在车站施工围挡外设置排水箱涵聚集区域内所有雨水及污水，箱涵上部可埋设其他管线。排水箱涵以金山大道为界东西两侧设置两路，两路均为自北向南流向，一路在车站西端头横穿金南一路最后在车站南端头与原有1400×1400箱涵对接，一路在车站东端头横穿金南一路最后在车站南端头与原有1400×1400箱涵对接。考虑后期工程施工需要，在施工区内设置排水系统，施工区施工废水及雨水最后都将聚集于排水箱涵。在通过交通倒改区域时采用1200砼管连接，顶管法施工。2、车站南北向军缆在车站沿西侧设置，军用光缆考虑到其重要性与普通通讯光缆分开布设，横穿段采用顶管法绕开车辆通过区域。3、车站在金南一路方向南侧设置燃气管，绕开车站结构施工区域，全段采用明挖法施工。4、其余沿金南一路和金山大道两侧分别设置地下管线，根据原有线路包括电力线、信息网络、自来水、电信等同沟设置于排水箱涵上方，改移管沟断面尺寸根据具体管线数量设置，深度均为2.0米，地下管线改移方案详见?东方马城站地下管线改移及保护示意图?。5.2 管线保护及改移方案东方马城站地下管线改移和保护分段进行，根据现有施工条件分段开挖，分段进行箱涵及预埋管的埋设工作。由于周边建筑物与基坑距离较小，车站地下管线利用建筑物与结构边线之间空间进行改移，由于局部管线预留工作井、检查井等，断面冲突部位根据现场条件错开留设。改移后地下管线仍在车站深基坑开挖影响范围内，同时承受上部荷载压力和较大的侧向压力，为了确保施工平安，施工过程中均需采取必要的保护措施，防止造成不必要的损失和危害。根据车站深基坑周边地下管线空间位置和施工顺序的关系，有针对性的对地下管线进行保护。当管沟内承压管外侧与导墙距离小于3.0米时，施工时需加深导墙深度，保证导墙底部在管线底标高以下至少1.0米。导墙沟槽开挖时及时喷护，同时严格控制土钉和网喷支护质量，防止先行改移的地下管线的位移或损坏。当管沟内承压管外侧与导墙距离大于3.0米时，地下管线可不作专项保护，但导墙沟槽开挖时按设计图纸要求及时喷护，同时严格控制土钉和网喷支护质量，防止先行改移的地下管线的位移或损坏。5.2.1 卧龙丽景湾东侧管线布设方案卧龙丽景湾临金山大道侧区域改移地下管线主要有电力管群、信息网络管群及600自来水管，由于自来水管承压，对基坑变形要求较高，因此在此区段内自来水管线埋设在箱涵内侧，军用光缆、电力管群、电信管群及信息网络管群在箱涵上部依次布设，具体详见图3所示。管线上部沟槽外延1.0米路面布置14200的钢筋网片，采用25cm厚C30混凝土硬化。网片钢筋与导墙或路面硬化钢筋网连接，加强基坑外侧路面的整体性。图3 1-1剖面图3车站南端头受加固区的影响，水务局宿舍与捷达出租车公司段地下管线较多，且施工断面较小，在施工围挡下方进行地下管线的改移，地下管线改移时撤除施工围挡，进行地下沟槽的开挖工作，施工难度大；考虑端头加固时对地下管线的影响较大，管线保护要求高；且受周边人行道路的通行条件制约，工期要求紧。根据以上施工条件，此段地下管线改移及保护采用1200管涵过渡，及时采用24cm厚C30混凝土进行路面硬化，尽快恢复人行道交通能力，然后直接在管涵中进行其他管线的埋设工作，具体布置详见图4所示。图4由于横穿腰路堤路设置，在转角部位局部管线为了设置检查井和工作井，管线间不得重叠设置；同时考虑燃气管不得设置在其他管线下方，施工时将管沟加宽至3.0米，此段地下管线改移及保护详见图5所示。图5施工围挡边缘地下管线改移，受排水线路坡度的影响，排水管道小坡度调整，开挖深度较大，此段地下管线改移及保护详见图6所示。图65.3 管线改移施工步骤5.4 管线保护措施5.4.1 地下管线施工监测地下管线监测主要采用观察和仪器监测的方法。电力、电信、通信、交通控制等管线受沉降影响不大，在不出现很大沉降或位移的情况下，管线一般不会被破坏，因此可采用观察路面的方法进行监测。针对沉降变形比拟敏感的燃气管道和自来水、排污管道，应在管道接头和中部位置设置沉降监测点，安装形式详见图7、图8所示。图4 图7 抱箍式埋设示意图图5 图8 模拟式埋设示意图同时根据权属单位要求设置变形限值，定期对管道变形进行监视测量，如果变形速率过快或累计变形量超限，均应及时处理。燃气泄露通常伴有气味、声音、管道压力表变化等现象，观测时注意这些常见现象是有效的监测手段。管线变形较大的时候可采用燃气检测仪表进行密切监测。自来水管监测可参考输气管道。由于自来水承压较大，一旦泄露容易造成土体崩塌，通过观察土体渗漏水、软化、滑动等现象能够较早发现问题。污水管渗漏也容易造成土方崩塌，危害性较自来水较小，观测方法可参照自来水管道。5.4.2 地下管线变形处理1燃气管道燃气管道一旦变形过大，会造成破损或接头脱落，燃气泄露。发现泄露后应立即切断附近施工用电、用火，现场进行紧急处理，再通知相关部门进行维修。管道造成破损的，可先采用管箍或管卡进行包裹处理，街头脱落的可将接头回复原位，在管口缠上密封胶带。处理后应查明管道破损或接头脱落的原因，排除危害物，再进行管道复位。施工过程中应防止管道弯曲过大，管道恢复后对管道四周根底进行加固，防止再次移位。2自来水管道自来水管道破损可使用快速接头处理。自来水管道在管道错动较大时，容易出现接头漏水，可将管道调直后，有快干水泥封堵接头部位，直到无水渗出再进行处理。拐弯处还需要重新制作支墩固定。3污水管污水管处理可参照自来水，接头部位也可采用注入聚氨酯堵漏。4电力管线电力电缆发生泄露时应立即疏散附近人员，在平安距离外设置好警示装置，禁止靠近，并联系供电部门切断电源后进行维修。5其他管线其他管线发现损坏时应保护好现场，防止人员靠近，同时联系相关部门进行维修。平安。5.4.3 管理组织措施为了做好公用管线保护工作，强化“谁承包、谁负责的原那么，本工程实行公用管线保护责任制，工程经理部经理为本工程的公用管线保护责任人。1明确工程地下管线工作的责任人和专职管线保护监督员，熟悉周边地下管线原始及改移后埋设情况，并在施工平面图上详细标明，同时根据施工需求及时提出具体的保护措施。2坚持按照政府有关要求办理有关手续和对管线的监护，要求有关单位进行现场交底监护工作。3对需进行加固保护的管线，召开管线协调会，拟定加固方案。工程施工中，严格按照确定的管线加固方案进行实施。并有管线监护人员和施工单位专职管线监护员进行双监护。出现问题，立即停止施工，并上报业主及有关单位。4进行信息化施工，严格执行信息反溃机制，加强对因施工而影响范围的构筑物和地下管线动态变化的监控，根据监测数据变化的情况，及时调整施工方案，确保道路与地下管线的正常运行。5定期召开与有关管线单位的配合会，随时掌握有关管线的情况，为施工效劳。6在施工过程中，遇到管线有异常现象或管位有差异，可能对地下管线的平安和维修产生影响时应立即停止施工，同时与相关管线单位联系，落实保护管线的措施前方可继续施工。7施工时，施工管理人员必须向现场施工人员作好保护地下管线的交底工作，如因管理不善，措施不当而造成管线事故的有关人员，公司将进行严格处理，以确保地下管线和构筑物的平安。5.4.4 其他保护措施1电气、焊接等容易产生火花的施工场地与燃气管道应保证平安距离。2在管线位置设置明显标志牌，防止碰撞管线，尽量防止重型机械和车辆靠近。3在管线外侧设置截排水沟，减少地面水流渗入，防止土体浸水沉降，造成管线破坏。4有条件的情况下应配备各种检测仪器，对燃气泄露、电力泄露等进行重点检查，尽早发现问题。5设置专人负责管线日常巡查工作，发现问题及时处理，并形成纪录。6与相关部门保持密切联系，一旦出现问题，尽快通报，协商处理方案，进行问题处理。7管道处理施工需委托专业的施工单位进行，保证施工质量和平安。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 comprehensive strictly strategic plan, implementation in accordance with the rules and discipline to manage the party, strengthen inner-party 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; < 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 second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party; the third part introduces two party regulations modified the main changes and needs to grasp several key problems; 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 2021 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; follow the correct direction, grasp the limited goals, adhere to the party'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 party'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 party's eighteen years comprehensive strictly practice. (a) revised two regulations of the party need of < the ICAC guidelines > in < in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) > based on revised, the promulgation and implementation of January 2021, 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 complicated, "eight prohibition, 52 are not allowed to" hard to remember, and also difficult to put into practice; the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements; the third is banned terms and discipline law, both with the party discipline, disciplinary regulations repeat and Criminal law and other laws and regulations repeat; the fourth is to "clean" the theme is not prominent, not for the existing problems, and is narrow, only needle of county-level 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 the party play very important role. Along with the development of the situation, which many provisions have been unable to fully meet the comprehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and criminal law and other countries laws and regulations Repetition; two is the political discipline regulations is not prominent, not specific, for violation of the party constitution, damage the authority of Party Constitution of misconduct lack necessary and serious responsibility to pursue; third is the main discipline for the leading cadres, does not cover all Party members. Based on the above situation, need to < the criterion of a clean and honest administration > and < rule > the two is likely to be more relevant regulations first amendment. By revising, really put the authority of Party discipline, the seriousness in the party tree and call up the majority of Party members and cadres of the party constitution of party compasses party consciousness. (II) two party regulations revision process the Central Committee of the Communist Party of China attaches great importance to two regulations revision . Xi Jinping, general books recorded in the Fifth Plenary Session of the eighth session of the Central Commission for Discipline Inspection, on the revised regulations < > made clear instructions. According to the central deployment, the Central Commission for Discipline Inspection from 2021 under six months begin study two regulations revision. The Standing Committee of the Central Commission for Discipline Inspection 4 review revised. Comrade Wang Qishan 14 times held a special meeting to study two regulations revision, amendment clarifies the direction, major issues of principle, path and target, respectively held a forum will listen to part of the province (area) secretary of the Party committee, Secretary of the Discipline Inspection Commission, part of the central ministries and state organs Department The first party committee is mainly responsible for people, views of experts and scholars and grassroots party organizations and Party members. Approved by the Central Committee of the Communist Party of China, on 7 September 2021, the general office of the Central Committee of the Party issued a notice to solicit the provinces (autonomous regions, municipalities) Party, the central ministries and commissions, state ministries and commissions of the Party (party), the General Political Department of the military, every 3 people organization of Party of two regulations revision opinion. Central Commission for Discipline Inspection of extensive solicitation of opinions, careful study, attracting, formed a revised sent reviewers. In October 8 and October 12, Central Committee Political Bureau Standing Committee and the Political Bureau of the Central Committee After consideration of the two regulations revised draft. On October 18, the Central Committee of the Communist Party of China formally issued two regulations. Can say, two laws amendment concentrated the wisdom of the whole party, embodies the party. Second, < code > and < Regulations > revision of the basic principles of two party regulations revision work and implement the party's eighteen, ten eight plenary, the spirit of the Fourth Plenary Session of the Eleventh Central Committee and General Secretary Xi Jinping important instructions on the revised < low political criterion > and < Regulations >, highlighting the ruling party characteristics, serious discipline, the discipline quite in front of the law, based on the current, a long-term, advance as a whole, with Bu Xiuding independent < rule > and < rule >. Main principle is: first, adhere to the party constitution to follow. The constitution about discipline and self-discipline required specific, awaken the party constitution of party compasses party consciousness, maintaining the authority of the constitution. General Secretary Xi Jinping pointed out that "no rules, no side round. Party constitution is the fundamental law, the party must follow the general rules. In early 2021 held the eighth session of the Central Commission for Discipline Inspection Fifth Plenary Session of the 16th Central Committee, Xi Jinping again pointed out that constitution is the party must follow the general rules, but also the general rules." the revision of the < code > and < rule > is Method in adhere to the regulations established for the purpose of combining rule of virtue is to adhere to the party constitution as a fundamental to follow, the constitution authority set up, wake up the party constitution and party rules the sense of discipline, the party constitution about discipline and self-discipline specific requirements. 4 second is to adhere to in accordance with the regulations governing the party and the party. The Party of rule of virtue "de", mainly refers to the party's ideals and beliefs, excellent traditional style. The revised the < code > closely linked to the "self-discipline", insisting on the positive initiative, for all members, highlight the "v
