电缆路径设计方案翻译-中英对照
项目经理将提供图纸，以说明电缆路径及设计电路的位置。项目经理应尽可能的为承包商提供当前的电缆记录以及其它服务；其准确性尚不能得到保证。
在开始现场施工之前，承包商应负责获取确切的且经批准的各条路径及位置，并向所有相关的权利机构发布《意愿通知书》。在工程施工期间，承包商还应遵守交通部门颁布的相关法规，涉及交通信号，交通转向，综合交通控制等方面。
承包商有责任防止对现有业务和现存的电缆造成损害。当对现有业务造成损害时，对维修与更换成本应在投标文件的第四部分和第五部分中有明确规定。承包商有责任承担在合同工程执行过程中为弥补损坏所产生的任何费用。
电缆的安排以及铺设与安装的方法都应经过项目经理的批准。
安装半径应尽可能大；沿路径的最小值应为25D，且靠近接缝和终点的应为15D（D为电缆的总直径）。
13.2.2.2 挖掘
土壤类型
为了达到描述工程规范的目的，根据德国电气工程师协会标准VDE 0210，表12的要求，引用以下关于土壤类型的定义：
•土壤类型1：非凝聚性土壤/沙，松散，半稠密
•土壤类型2：非凝聚性土壤/沙，稠密，灰色，粗且均匀，大颗砂砾，石子，碎石，分成不同等级的
•土壤类型3：粘结性土壤/非常软，软，纯粘着性，带非凝聚性添加剂且柔软的，坚固的，纯粘着性
•土壤类型4：粘结性土壤/带非凝聚性添加剂且坚固的，纯粘着性且硬质的，带非凝聚性添加剂且硬质的，纯粘着性且坚固的，带非凝聚性添加剂且坚固的。
•土壤类型5：有机土壤以及带有有机添加物的土壤
•土壤类型6：有相当大裂缝的岩石
•土壤类型7：未分解但带有小裂隙的岩石
基于以前挖掘工程的经验，一般本工程区域内的土壤都被归纳为类型2，3，4和/或5，也有可能属于类型6，但一般这种情况被认为是最少见的（<1%）。
投标人应在考虑到以上因素的前提下，提供挖掘工程的速率。
对土壤类型1和类型7进行具体挖掘作业的设备速率必须分别在日程表里标明；这些装置的速率必须适用于实际操作；操作实例必须是获得项目经理的同意批准的土壤类型。
注：上述定义和指南说明也适用其它任何挖掘作业；包括电线杆竖坑和电缆级安装的挖掘作业。
每个电缆沟和竖坑的精确位置必须获得项目经理的同意。
电缆沟必须为直线；边必须为直线并且不得有任何尖锐的材料/可能损坏电缆或者附件的边缘，电缆沟底部将必须牢固和轮廓必须平整，并且不得有任何尖锐的材料//可能损坏电缆的石块。
在电缆在铺设之前，电缆沟必须填充一层至少最小80毫米厚的柔软的筛选沙料，形成平整的底部。电缆沟从人行道到车行道处，或者其它标准必须发生变化的位置，电缆沟的底部将逐渐倾斜。 承包商必须采取所有必要的措施，防止因滑动或者电缆沟墙壁断裂对道路或者地表面造成的损坏；
承包商必须处理对水进行处理，以防止对电缆造成任何危险，包括对电缆沟造成不良影响铺设的其它材料。承包商必须提供全部的泵材，需要的井点和装备，并执行全部必要的泵送和排水作业。合同价格必须考虑所有这方面设备和操作。
承包商必须对公众安全负责，并且提供沿电缆沟的线路而设的栅栏和绳索，以及在夜晚的危险通知，障碍和红灯警告。电缆沟每300米安排一名值夜人员。
除非获得批准，在挖掘作业期间，必须制定相关规定，对进入线路附近的财产和场所的人员和车辆进行检查。确保该制度的实施，直到临时修复作业已经完成。
项目经理有权决定，进入措施是否有不完善之处， 承包商必须安装最小内径150毫米的PE或者PVC管，并且在项目经理在场的情况下，排成直行并将电缆被回填到电缆电缆沟。合同价格必须包括这些管材的供应和安装以及所有这方面的操作。
铺设人行道的挖掘作业必须特别小心的进行。当移除铺设的板坯时，承包商必须采取必要预防避免破损。
当电缆沟与现有的设施，电缆，管材平行时，在现有的设施和新电缆沟的边缘之间，承包商必须至少保持0.5米的距离。穿过现有的设施时，承包商必须特别小心并且将保证设施完好无损。关于穿过现有的设施的方法，承包商必须提前获得项目经理的书面批准。
电缆管道处完工后的土堆，必须和正常的地面相同。电缆埋设的深度符合附件3图纸的要求或者项目经理要求低于线路平面的深度。
The Project Manager will supply final drawings showing the cable routes and the locations of proposed circuits. The Project Manager will assist the Contractor by providing records of existing cables and other services, wherever possible; the accuracy of which cannot be guaranteed.
Before commencing work at site, the Contractor shall be responsible for obtaining the exact approved routes and locations, and shall issue "Notices of Intent" to all authorities concerned. He shall further¬more obey all relevant rules as applied by the Traffic Department with reference to traffic signs, diver¬sions and general traffic control, during the performance of his work.
The Contractor shall be responsible for precautions to prevent damage to existing services and elec¬tric cables. Damage to services, cost of repairs and replacements shall be managed as described in Sections IV and V of these bidding documents. The Contractor shall be liable for any costs for making good such damage caused in the execution of the contractual work.
All arrangements of cables and methods of laying and installation shall be subject to the approval of the Project Manager.
Installation radii shall be as large as possible; the minimum shall be 25 D along the route, and 15 D adjacent to joints and terminations {D being the overall diameter of the cable).
13.2.2.2 Excavation Soil Types
For the purpose of describing the work specifications the following definitions for the soil types in ac¬cordance with VDE 0210, Table 12, shall apply;
Definition of soil types for works associated with excavations:
« Soil Type 1: Non-cohesive soils / sand, loose, semi-dense
• Soil Type 2: Non-cohesive soils/ sand, dense, grave, bolder uniform, gravel-grand, stones, mac¬
adam, graded
« Soil Type 3: Cohesive soils / very soft, soft, purely cohesive, soft with non-cohesive additions, firm, purely cohesive
• Soil Type 4: Cohesive soils / firm with non-cohesive additions, stiff purely cohesive, stiff with non-
cohesive additions, hard purely cohesive, hard with non-cohesive additions
• Soil Type 5: Organic soils and soils with organic additions
• Soil Type 6: Rock with considerable fissuring
• Soil Type 7: Rock not decomposed conditions with minor fissuring
Based on the previous experience of excavation works, the general soil types in the project area is considered to be of type 2, 3, 4 and / or 5 in general with type 6 a slight possibility but believed mini¬mal (<1%).
Before submitting his bid, the Bidder shall satisfy himself concerning the nature of the ground likely to be encountered during operations.
The Bidder shall provide the rates for excavation works taking above facts into consideration.
Unit rates for specific excavation works in soil types 1 and 7 shall be provided separately in the price schedules. These unit rates shall be applicable in actual cases where these soil types are encoun¬tered subject to the approved of the Project Manager.
Note: The above definitions and guidelines shall also be applicable to any other excavation works in¬cluding excavation of pole pits and installation of poles.
The exact location of each trench and pit shall be subject to the approval of the Project Manager.
The trenches shall be straight, the sides shall be straight and free from any sharp material/edges likely to damage the cable or accessories, the trench bottom shall be firm and of smooth contour and shall be free from any sharp materials/pebbles, likely to damage the cables.
The trench shall be filled with a minimum 80 mm thick layer of soft and sieved sand to form a smooth bedding before the cables are laid. Where trenches pass from a footway to a roadway, or at other po¬sitions where a change of level is necessary, the bottom of the trench shall slope gradually. The Con¬tractor shall take all precautions neces$ary to prevent damage to the road or ground surface due to a slip or breaking- away from the side walls of the trench.
The Contractor shall deal with and dispose of water so as to prevent any risk of the cables and other materials which are to be laid in the trenches being detrimentally affected. He shall provide all pumps, well points and appliances required and shall carry out all necessary pumping and bailing. The con¬tract prices shall allow for all such equipment and operations.
The Contractor shall be responsible for public safety and hence shall provide picket fences and ropes along the routes of open trenches, as well as danger notices, barriers and red warning lights during the hours of darkness. A watchman shall be provided for every 300 m of open trench.
Unless otherwise agreed, provision shall be made during excavation for reasonable access of persons and vehicles to property or places adjacent to the route. This provision shall be maintained until in¬terim restoration has been completed.
Where, in the opinion of the Project Manager, other access measures prove unsatisfactory, the Con¬tractor shall install PE or PVC pipes of 150 mm minimum internal diameter at the level and in align¬ment with the cables are to be laid and backfill-this section of the cable trench immediately thereafter in the presence of the Project Manager. Supply and installation of the pipes as well as pulling through the cables are deemed to be included in the contract price.
Excavation in paved sidewalks shall be carried out with special care. When removing paving slabs, the Contractor shall take the necessary precautions to avoid breakage.
Whenever trenches run parallel to existing services, cables, pipes, the Contractor shall maintain a dis¬tance of at least 0.5 m between the existing services and the edge of the new trench. The Contractor shall cross existing services with the outmost care and shall ensure that the services are adequately protected. He shall obtain the written approval of the Project Manager in advance, concerning the method of crossing existing services.
Where mounds of earth exist on the cable routes as finally approved, they shali be cleared to the nor¬mal ground level. Cables shall be laid to a depth as indicated in the drawings of Annex 3 or at the level given by the Project Manager below the road level.
