过河纜支架采用預制鋼筋混凝土支柱,以及吊装竪立装配的施工方法,比用排架模板浇筑的方法在工程费用及施工时間上均大为节省,而且前一种方法的支柱是在地面上預制的,因而质量上也更有保証。广东省曾先后在馬径寮站和黎市站使用过这种施工方法,都收到預期效果。馬径寮站的支柱系圆环形截面的电綫杆(在市面上购买),內、外径分別为20和30厘米,采用400标号的混凝土,內配置14根φ12毫米的鋼筋,杆全长18米(由三段各长6米
Crossing the cable support using precast reinforced concrete pillars, as well as erection of the erection of the construction method, than the use of the formwork pouring template in the construction costs and construction time are greatly saved, and the former method is the pillars of the ground On the prefabricated, so the quality is also more guaranteed. Guangdong Province has successively used this construction method at Ma Daliao Station and Li-Shi Station, and all received the expected results. The pillar of Ma Daliao Station is a torus (commercially available) with a circular cross-section, 20 and 30 cm inside and outside diameters, respectively. It is made of concrete with 400 marks and is equipped with 14 pieces of φ12 mm steel bars. 18 meters long (three sections by 6 meters long
