Description

超长大截面电缆的机械敷设方法 The method of mechanically laying large long section of the cable

技术领域 FIELD

本发明涉及一种机械化敷设电缆的施工方法,尤其是涉及一种超长大截面电缆的机械敷设方法。 The present invention relates to a method for the construction of mechanized laying of cables, particularly to a long section of the cable of large mechanical laying method.

背景技术 Background technique

电缆机械敷设有牵引敷设和输送敷设两种方式。 Mechanical traction cable laying and transporting laying laying two ways. 电缆牵引敷设通过机(电)动绞磨、卷扬机等牵引机械设备实现;电缆输送敷设使用电缆输送机完成。 By laying the cable pulling machine (electric) winch, winch towing machine and other equipment to achieve; cable conveyor conveyor cable laying is completed. 电缆牵引敷设通常用于电缆沿排管、桥(支)架、电缆隧道(沟)或直埋敷设,牵引敷设长度受电缆本体允许牵引力或导向装置附着架构强度的限制,两台及以上牵引机组成机组时,同步问题难以解决;电缆输送机多用于电缆埋地、沿电缆隧道或电缆沟敷设,存在一次性投资大、施工所需的辅助工作与设备多、敷设成本较高、沿电缆桥(支)架敷设电缆时难以实现一步到位等缺陷,敷设大长度电缆时,电缆输送机组难以解决因电源线路压降造成的不同步问题。 Pulling the cable laid along the row of tubes commonly used for cable bridges (branch) frame, cable tunnel (groove) or Buried traction cable lay length of the body by allowing the architecture traction or adhesion strength of the guide means limited, and two or more tractor when the composition of the unit, the synchronization problem is difficult to solve; cable conveyors used for underground cable laying cable along the tunnel or cable trench, there is a one-time investment, and more work needed to assist with construction equipment, high cost of laying along the cable bridge it is difficult to achieve in one step and other defects (branch) rack cabling, laying large length of the cable, the cable transport unit is difficult to solve the problem of synchronization due to a power line voltage drop caused.

由于电缆机械敷设受同步问题的限制,不能解决大长度电缆整根敷设的问题,目前电缆工程施工中,对于大截面电缆供电回路距离超过1500米时,均采用分段敷设、中间接头接续的方案实现。 Since the cable laying machine limits receiving synchronization, can not solve the problem of the large length of the cable laying whole root, the current in the cable construction, to a large section of the cable from the power supply circuit when over 1500 meters, the laying segment are used, the intermediate joint connection scheme achieve. 中间接头的存在加大了建设投资,增加了供电系统的故障率,降低了系统运行的可靠性,容易引发电缆火灾而造成重大损失。 There is the middle joint of increased construction investment, increase the failure rate of the power supply system, reducing the system's reliability, easily lead to cable fire caused heavy losses.

随着对建设项目规划水平、供电质量要求的不断提高,电缆沿电缆桥架敷设已成为工矿企业电缆工程首选的敷设方式。 With the continuous improvement of the level of construction project planning, power quality requirements, laying cables along the cable tray has become the first choice of industrial and mining engineering cable laying. 而电缆输送法敷设电缆,输送机体积和重量大,高处施工需要起重机配合安放,电缆敷设时电缆端头始终需要人力牵引和导向,用于电缆沿电缆桥(支)架敷设,尤其是沿构架悬挑安装的桥架敷设时,难以将电缆一次敷设到位。 Cabling and the cable delivery method, large size and weight of the conveyor, is placed with a crane requires high construction, when the cable headend cable laying always require human traction and guide, along the cable for the cable bridge (branched) laying frame, in particular along when laying the framework cantilevered bridge installed, it is difficult to lay a cable in place. 使用电缆输送机敷设电缆,一次性投资大,施工效率相对较低,施工成本高。 Cable conveyor cabling, one-time investment, the construction is relatively low efficiency and high construction costs.
