Cable leading-down well and method for laying cable in cable leading-down well
The invention belongs to the field of shaft construction, and particularly relates to a cable leading well and a method for laying a cable in the cable leading well, the cable leading well comprises a transverse well, a cable duct bank is arranged on the side edge of the transverse well, and a cable support is arranged in the transverse well; the vertical shaft is arranged on one side of the transverse shaft, a manhole is formed in the joint of the vertical shaft and the transverse shaft, and the manhole is higher than the cable duct bank. Due to the fact that the manholes are formed between the transverse wells and the vertical wells, the manholes are higher than the cable duct banks in the transverse wells, the manholes can prevent accumulated water from entering the tunnel, and therefore electrical equipment in the tunnel is prevented from being affected with damp and damaged. The invention discloses a method for laying a cable in a cable leading-down well. The cable penetrates into a transverse well from a cable duct bank; a cable is erected on a cable support which is arranged in a step-type rising mode; the cable penetrates through the manhole to enter the vertical shaft, and then penetrates through the pipe hole in the tunnel top plate to enter the tunnel; and after the cable is laid, the manhole and the pipe hole in the tunnel top plate are blocked, so that electrical equipment in the tunnel is prevented from being affected with damp and damaged.
本发明用于井道施工领域，特别涉及一种电缆引下井及电缆引下井中铺设电缆的方法，电缆引下井，包括横井，横井的侧边设有电缆排管，横井内部设有电缆支架；竖井，竖井设在横井的一侧，竖井与横井的连接处设有人孔，人孔高于电缆排管的高度。由于横井与竖井之间设置了人孔，人孔高度高于横井中电缆排管的高度，人孔能够防止积水进入隧道内部，从而避免了隧道内电气设备受潮及损坏。电缆引下井中铺设电缆的方法，电缆从电缆排管穿设到横井中；将电缆架设在呈台阶式上升排布的电缆支架上；电缆穿过人孔进入到竖井中，然后穿过隧道顶板上的管孔进入隧道；电缆铺设完毕后，将人孔和隧道顶板上的管孔进行封堵，避免了隧道内电气设备受潮及损坏。
