直埋电缆如果需要设井的话,

那应该在接头处设,


和电缆制造长度有


关。




一般穿管情况下设井。如:




电力工程电缆设计规范:



5.4.7


较长电缆管路中的下列部位,应设有工作井:




1


)电缆牵引张力限制的间距处。其最大间距,可按 本规范附录


F


确定。




2


)电缆分支、接头处。




3


)管路方向较大改变或电缆从排管 转入直埋处。




4

< br>)管路坡度较大且需防止电缆滑落的必要加强固定处。




民用建筑电气设计规范:



7.3.4.7


在线路转角、分支处应设电缆人孔井,在直线 段上,为便于


拉引电缆也应设置一定数量的电缆人孔井,


人孔井 间的距离不宜大于


150m




7.3.4.8


电缆人孔井的净空高度不宜小于


1.80m


,其上部人孔的直径


不应小于

< p>
0.70m





如果只是电缆穿钢管或者


PVC


,我觉得井的 距离不应该超过


30


米,


因为穿管线路 不允许超过


30


米。

管井的设置可以参考《电力工程电缆设计规范


GB 50217-2007


》:



5. 4. 7


较长电缆管路中的下列部位,应设置工作井:



1


电缆牵引张力限制的间距处。



2


电缆分支、接头处。



3


管路方向较大改变或电缆从排管转入直埋处。



4


管路坡度较大且需防止电缆滑落的必要加强固定处。




工作井的大小根据什么确定



根据电缆有关施工规范,电缆的弯曲半径不小于


20d.


通常高压电缆井要比低压电缆井大。


电缆井的大小和电缆的管群数和


电缆井位置还有关系。



我们做的低压 电缆井通常净尺寸


1



*1.2


米。



高压井至少净尺寸

2



*1.5


米左右





规范上是不超过


100m



但实际市政上都不超过


50m



一般


30-4 0m



这个主要是敷设电缆受机械的限制,

特别是大的电缆,


距离长了无法


拖动。
