(1) Determine the position of the indoor control box, that is, the position of the device to operate the telescopic door switch;
（2）将220V电源引到控制盒的位置下端,要求最好是再带1根接地线,粗细规格为1.37,而且有漏电保护装置,并采用PVC暗敷；
(2) Lead the 220 V power supply to the lower end of the control box, and it is required to take another grounding wire with the thickness of 1.37 and leakage protection device, and use PVC concealed laying;
（3）预留￠32mm PVC管道,从控制盒的位置下端往下至地平面以下,穿墙往外,至轨道大致位置地平面下0.1-0.15米处,供以后伸缩门室外线路入室；
(3) Reserve ￠ 32mm PVC pipe from the lower end of the control box to below the ground level, through the wall to the outside, to 0.1-0.15 m below the ground level of the track approximate position, for the future expansion door outdoor line to enter the room;
（4）按照上表得出门洞长度井盖钢模具 U型槽模具 天津水处理设备 检查井钢模具 保定公司注册 u型槽模具 流水槽模具 ，砌门洞时洞宽内净空不小于0.75-0.8米,高度内净尺寸普通门不小于门高+0.25米,豪华门不小于门高+0.1米;门洞末端里侧中上端留宽0.4米,高0.6米检修孔,有条件的可将门洞总长度再加长0.2-0.3米,这样可将检修孔改成一扇小门,方便日后检修维护伸缩门电气线路；
(4) According to the above table, the clearance in the width of the door opening is not less than 0.75-0.8 m, and the net size in the height is not less than + 0.25 m for ordinary doors and + 0.1 M for luxury doors. A 0.4 m wide and 0.6 m high manhole is reserved at the middle and upper end of the inner side of the door opening. If possible, the total length of the door opening can be lengthened by 0.2-0.3 m, so that the manhole can be changed into a small door, It is convenient to repair and maintain the electrical circuit of the telescopic door in the future;
