The invention discloses a metro flexible contact line double-bearing and double-guide construction method which comprises the following steps: S1, after a ground line is sealed and hung, a worker climbs to the top end of a supporting column to surround a first steel wire rope sleeve around the supporting column, and then a first double-wire clamping device and a second double-wire clamping device at the two ends of the first steel wire rope sleeve are connected to a contact line respectively; S2, after the two double-wire clamping devices are connected to the contact wire, the middle of the first steel wire rope sleeve is connected to the supporting column through a first pulley and a first lever block, and the first lever block is shaken to be in a tightened state; S3, the supporting column is wound with a second steel wire rope sleeve and then connected with a second lever block, the lower end of the second lever block is connected with a balance weight, the balance weight is lifted, and at the moment, the anchoring insulator is in a loose state; s4, after the worker replaces the insulator, the second lever block is loosened; and S5, slowly relaxing is performed. According to the metro flexible contact line double-bearing and double-guide construction method adopting the structure, the structure is simple, the construction efficiency is improved, and the safety coefficient is high.

本发明公开了一种地铁柔性接触线双承双导施工方法，步骤包括：S1、在地线封挂完毕后，工作人员爬至支柱顶端将第一钢丝绳套绕支柱环绕后，将第一钢丝绳套两端的第一双卡线器和第二双卡线器分别连接在接触线上；S2、将两个双卡线器连接在接触线后，第一钢丝绳套的中部通过第一滑轮与第一手扳葫芦连接在支柱上，将第一手扳葫芦摇至绷紧状态；S3、支柱上再缠绕第二钢丝绳套后与第二手扳葫芦连接，第二手扳葫芦的下端与坠砣连接，并将其提起，此时下锚绝缘子为松弛状态；S4、工作人员将绝缘子更换后，松开第二手扳葫芦；S5、缓慢放松，即可。本发明采用上述结构的一种地铁柔性接触线双承双导施工方法，结构简单，提高施工效率，安全系数高。
