Method and system for protecting cable
The invention discloses a method and a system for protecting a cable, and the method comprises the steps: S1, carrying out the measurement and positioning of a cable trench before the excavation of asubway foundation pit, and excavating a soil body above the cable trench; S2, constructing foundation pit continuous walls at the two ends of the cable pipe trench correspondingly, and reinforcing theouter sides of the foundation pit continuous walls; S3, constructing concrete coupling beam stand columns on the two sides of the cable pipe trench; S4, digging grooves in the arrangement direction of the concrete coupling beam stand columns, and arranging concrete reinforcing steel bars; S5, excavating soil below the cable duct trench in a segmented mode, erecting transverse profile steel belowthe cable duct trench of each segment, and welding and fixing excavation continues to be conducted after the transverse profile steel and the concrete reinforcing steel bars to the other side face ofthe subway foundation pit; S6, pouring concrete reinforcing steel bars to form a concrete connecting beam, and constructing a top beam; and S7, conducting excavation step by step below the top beam toform a subway foundation pit, and after excavation of each section is completed, conducting reinforcement treatment on each foundation pit continuous wall, and then excavating the next section till the bottom face of the subway foundation pit is excavated.
本发明公开了一个保护电缆的方法和系统，步骤包括：S1：在地铁基坑开挖前对电缆管沟测量定位，开挖电缆管沟上方的土体；S2：在电缆管沟的两端分别施做基坑连续墙并对基坑连续墙的外侧作加固处理；S3：在电缆管沟的两侧施做混凝土连梁立柱；S4：沿混凝土连梁立柱的排列方向开挖沟槽，设置混凝土钢筋；S5：分节段开挖电缆管沟的下方土体，在每一节段的电缆管沟的下方架设横向型钢，将横向型钢与混凝土钢筋焊接固定后继续开挖，直至地铁基坑的另一侧面；S6：浇筑混凝土钢筋形成混凝土连梁并施做冠梁；S7：在冠梁的下方逐级开挖形成地铁基坑，在每一节段开挖完成后，在每一个基坑连续墙上分别作加固处理后再开挖下一节段，直至开挖到地铁基坑的底面。
