position-related consumption of civil servants has been swept by finance, consumer, regardless of cost, extravagance and waste in the civil service position-related consumption, abuse, corruption and embezzlement, corruption is important. Then, under the conditions of market economy, how to reform the existing civil duty consumption management, explores a source to prevent and curb the post consumption corruption way, is currently a major issue faced by honest work. Recently, I conducted research on this issue, this problem on some humble opinions. First, the existing public servants duty consumption the main problems seen from the investigation and reasons, in recent years, public servants duty consumption caused by the abuses and not a person of integrity, is one of the major problems in the party in Government, its operation order have a negative effect on the party and Government organs, seriously damaging the image of the party and the Government, undermining the relationship between party and the masses, effect, opening up and economic construction. From I County in recent years of governance situation see, positions consumption in the produced of two not phenomenon rendering four a features: a is positions consumption system lost has due of binding, right is greater than rules, and right is greater than method of phenomenon more highlight; II is in positions consumption in the Camera Obscura operation, using terms, will positions consumption into has personal consumption, will corporate points to into personal points to, makes positions consumption in some aspects has into positions enjoy and self-dealing of means; three is to positions consumption for name, fraud, false impersonator, Trend of negative corruption phenomena such as corruption and misappropriation; four palaces, follow the fashion, rivalries, wasteful, and post consumption became a symbol of showing off their individual capacities. Caused by public servants duty consumption of many two phenomenon in which people reflect the biggest problems are: (a) the official car problems. Mainly in three aspects: one is the larger buses cost expenditure. According to statistics, until November 2003, XX County township Department bus 159 cars, which department owns the bus 145 vehicles, and showed an increasing trend. Financial expenses cost per bus per year to 35,000 yuan, and in fact every cost up to 50,000 yuan. Some units also hiring temporary drivers and expenditure on wages and subsidies. Necessary to keep a car, but also dependants, leading to larger expenses. Second, gongchesiyong breed unhealthy tendencies. Some people believe that now some bus drivers use one-third, one-third leading private one-third used for official purposes. Some public servants, especially leading officials motoring, cars for private purposes, violating the self-discipline regulations, and even lead to traffic accidents. According to statistics from related departments, since 2004, the correct investigation in our County serves nearly 30 cars for private purposes, only the first half of this year, cars for private purposes or 宣化化工厂35kv架空线路施工方案目录一.概况二.施工前准备三.施工程序流程图四.施工方法 五.质量与安全 一.概况 本工程项目，是利用宣炼可油液化中的丙烯为主要原料建设年产一万吨硝铵原料装置.化工厂35kv输电线路是该厂的主要电源线路,线路由榆林开关站经人头山到化工厂35kv变电所,全程约28km,设计投资347万元.化工厂，35kv输电线路工程包括改线工程和新建线路工程两部分。改线工程将原一、二回从热电厂出线侧5#杆至高新建设区10#杆拆除，新架设一条双回路共杆线路，绕过化工厂区再接上荆宝一、二回线路。新建线路工程由35千伏变电所（待建）建设一线路顺1号站一、二回线路走向至榆林开关站。本工程线路全长28公里，其中双回路15公里，全线路共杆基142基，其中铁塔37基（改线工程14基，新建工程13基），焊接凝土杆35基，包括转角耐张龙门杆17基，直线杆18基。全线路工程的完成，需拆除原有35千伏线路约3.9公里，包括改线工程将原一、二回路从5#杆约1.2公里，新建工程在6#杆处无法跨8号站至国防工程35千伏线路，需将其路拆除1.5公里。本工程地形复杂高差大，施工条件较差，全线路通过深草山地弹高山松林，最大地形高差50米以上，通过松林0.5公里，山坡草地1.5公里，全线路经过跨越高低压线路十多处，铁路公路1处，河流、水塘2处。 二,施工前的准备施工前技术人员向施工班组作技术交底，组织学习施工图，施工验收规范和质量标准，介绍施工程序、施工方法和安全技术措施，使施工班组在施工前掌握施工要求，保证施工顺利正常进行。施工人员在施工前要熟悉施工现场，施工线路、地形条件，作到心中有数。施工前根据需要的工具和材料进行认真检查，必符合质量和安全要求，铁塔在施工组立前，先进行予组装，检查合格后再运施工现场。三,施工程序流程图（见附图） 四, 施工方法 1.原材料及器材检验 架空电力线路使用的线材,不得有松股.交叉.断裂及破损;不应有严重腐蚀等现象.钢绞线.镀锌铁线表面的镀锌层应良好,无锈蚀.绝缘线表面应平整.光滑.色泽均匀.由黑色金属制造的附件和紧固件,除地脚罗栓外,应用热镀锌制品.各种连接罗栓的防松装置弹力应适宜,厚度应符合规定.金属附件及罗栓表面不应有裂纹.砂眼.锌皮脱落及锈蚀等现象.罗栓与罗母配合应良好.金具组装配合应良好,表面光洁.无毛刺.飞边.砂眼.气泡.镀锌良好无锈蚀.线夹转动灵活.与导线接触面符合要求.瓷件与铁件徂合无歪斜.瓷釉光滑.无裂纹.缺釉.烧痕.气泡等缺陷.弹簧销.弹簧垫的弹力适宜.环形钢筋砼电杆表面光洁平整.无露筋.跑浆现象.杆身无纵向裂纹.横向裂纹的宽度不应超过0.1mm.弯曲不应超过杆长的1/1000.底盘.卡盘.拉线盘不应有蜂窝.露筋.裂纹等缺陷其强度应符合设计要求. 2.分坑测量a直线杆的分坑测量单杆分坑时,在杆位中心桩设测点,安置仪器.前视或后视相邻杆塔位中心桩,在需排杆位置的反方向,定两个辅助桩,两桩相距2至3米,供底盘找正用.在杆位中心按要求划出坑口. 1# 2# 3# 辅1 辅2 线路中心线b.双杆分坑在杆位中心点安置经纬仪,水平度盘对0度,前视或后视相邻杆塔中心桩.然后仪器转90度,左右各定一个辅助桩,供底盘找正用.根据坑口边长和双杆开档确定坑口位置.

Third, high efficiency and low cost of the bus. Surveys show that, the operating costs of taxis for the 8200/. Is a fundamental priority of the reform, it is a difficult problem that must be solved in the reform process. Clearly, the post consumption averages three years before as a base and fine-tuned on the basis of this single practices must be improved. Improvements to adhere to three principles: first, under the existing policy provisions approved for public servants duty consumption standards, calibration, is not contrary to policy. Second, according to the local financial situation and peoples sustainability, public servants duty consumption standards approved, both financial reach, and people passing through. Third, according to the operational needs of civil servants responsible for authorized public servants duty consumption standards, both high and low positions, but also the nature of the work and the workload. In reform of method Shang, approved civil servants positions consumption standard to big unified, and small dispersed suitable, that most positions consumption project should according to policy provides proposed unified standard, consider to ranks, and units and the work task of differences sex, unified of standard should has elastic of and dynamic of, makes regions, and units in implementation unified standard Shi has must of flexible disposal right; but since set of standard must after financial, and audit, sector audit approved Hou to implementation. (C) reform package. Public servants duty consumption elasticity of consumption to limit consumption, turning mess into kitchen after dinner, follow the civil servant with a how to use personal title subsidies, or how to manage a personal duty consumption use of subsidies. Therefore, we must establish and perfect with public servants duty consumption monetization reform support of the series of g
