各管线平面位置与立面高程的施工测量管理The pipeline construction of plane position and elevation elevation measurement management 跟着城市建造开展,组团性的居住小区规划的扩展,居住小区的容积率和建筑面积的添加,小区市政配套公用设施,如给水管、排污管、雨水管、煤气管、电力电缆、电讯等管线均选用无杆化,归纳管网越来越杂乱。这些管线的安置假使缺少归纳思考,管线安置欠合理,将致使重复开挖路面,费时费工,也造成了人力、财力、物力的糟蹋。因而,小区归纳管网工程的安置,应从描绘、施工、检修、安全和防护安全等方面来进行质量操控。怎么对小区归纳管网工程进行质量操控,是摆在建造、描绘、施工及监理单位面前的重要课题。以下笔者依据个人的工程经历做一些剖析与剖析。Group sex with built in cities, the expansion of the residential area planning, residential area, plot ratio and building area to add, district municipal public facilities, such as feed pipe, drainage pipe, storm sewer, gas, electricity, cable, telecommunications, such as pipeline selects the rodless, network is more and more cluttered. Placed these pipes if lack of inductive thinking, pipeline settlement owe is reasonable, will cause repeated excavation surface, time consuming work, also contributed to the human, financial and material resources. Resettlement village induction pipe network project, therefore, should be painted, construction, maintenance, safety and protection, etc, to carry out quality control. How to induce pipeline engineering quality control to the village, is placed in front of construction, paints, construction and supervision units of important topic. The following the author on the basis of personal experiences to do some engineering analysis and profiling. 做好管线的施工资料办理，首要，对外网工程首要资料、设备限价限品牌、树立出场资料及配件申报准则。首要管材、阀门出场前，需求施工单位提早报验，应审阅其出厂合格证书、技能功能检测陈述、准用证等能否完全有用，能否契合描绘和关联标准需求，不合格的资料及配件禁绝出场。其次，对出场的管材和管件，专业工程师按批量进行查看，查看种类标准和外观质量，以避免以次充好，资料什物与报验不符。最终，管道运用的阀门，如截止阀、闸阀、球阀、蝶阀等也是操控的要点。Pipeline construction material to handle first, primary, primary materials, equipment price limit foreign web project brand, sets up the rule of material and accessories to declare. Primary pipe, valve before, demand construction unit inspection, early should review its certificate of quality, skills, function testing before delivery statement, apply mutatis mutandis to certificate whether completely useful, whether it can fit and related standard requirements, the unqualified materials and accessories to calls. Second, the appearance of pipe and pipe fittings, professional engineers according to the batch to check, check standard and appearance quality, in order to avoid shoddy, things do not tally with the inspection data. Eventually, pipe valves, such as cut-off valve, gate valve, ball valve, butterfly valve, etc. Also control points. 查看出厂质量合格证书与阀门上的铭牌能否相符，类型、标准、压力运用范围、密封等能否满意描绘需求。不仅如此，装置前还应查看阀门开闭能否灵敏，必要时，还应按施工检验标准的需求进行强度和严密性试验，合格后方可运用。Check the factory quality certificate and the valve of the nameplate whether conform to, type, standard, pressure use range, such as sealing can satisfied requirements. Not only that, the machine should also check the valve open and close can be sensitive, when necessary, should also meet the requirements of construction inspection standard for strength and leak test, qualified rear can use. 做好各管线平面方位与立面高程的施工丈量办理，首要，专业工程师有必要仔细了解施工图，组织做好描绘技能交底，加强对小区管线平面方位和立面高程的预控。其次，生态带各专业施工前应先放线后，由专业工程师一致验线，签字承认后方可开槽。场所平坦、土石方工程、外线归纳管沟及单管管沟开挖、管沟回填、条件若是答应最佳由一家施工单位施工，便于办理和协调，可加速外线工程进度和下降工程造价、管沟回填质量有疑问有土石方施工单位担任，各专业公司做好合作，供给有关技能资料。再次，管线穿插较多的丁字和十字路口，是管线立面高程操控的要点和难点部位，锅炉省煤器在此部位管线相互“打架”层出不穷。Do the pipeline plane azimuth and elevation elevation construction measure to deal with, first, professional engineer is necessary to understand the working drawing carefully, organization ready to describe skills so as to strengthen precontrol of pipeline plane azimuth and elevation elevation. Second, pay-off should be taken before each professional construction, test line, by professional engineers sign acknowledge rear can slot. Place flat, engineering, perimeter induction pipe trench and single pipe trench excavation, backfilling for pipeline, if conditions are promised the best by a construction unit construction, easy to handle and coordination, can accelerate the perimeter construction schedule and decrease project cost, pipe trench backfill quality in doubt have conditions of construction unit, the professional company to do cooperation, supply information on skills. Again, pipeline with more tee and crossroads, are piping elevation elevation control point and the difficulty, in the parts of the pipeline fight each other emerge in endlessly. 做好各专业管线的施工次序办理，对于小区管网的特色，联系施工现场的具体情况及公司对工期的需求，科学、合理、统筹组织住宅小区各专业管线的施工次序，并进行有用操控农用拖拉机。首要，组织施工次序，坚持“四让”准则。Completes various professional pipeline construction order to deal with, the community characteristic of pipe network, the contact details of the construction site and the demand of time limit for a project, scientific and reasonable, the organization as a whole residential area of each professional pipeline construction sequence, and useful. First, the organization construction order, adhere to the four principles.
