Construction method for reinforcing existing lines of heavy haul railway in karst area
The invention relates to a karst area heavy haul railway existing line reinforcement construction method which comprises the following steps: carrying out underground hole body detection on an existing line, and determining a reinforcement construction area; a hanger rail beam is arranged on the existing line, and the hanger rail beam penetrates through all the reinforcing construction areas; the positions of optical cables and electric cables of the existing line are ascertained and protected, a plurality of grouting hole sets are distributed in the reinforcement construction area, drilling and grouting are conducted at the positions of the grouting holes, after grouting is completed, the electric cables and the optical cables are restored to the original positions, and the hanger rail beam is dismantled. According to the reinforcement construction method for the existing line of the heavy haul railway in the karst area, by arranging the hanger rail beam and protecting the optical cable and the electric cable, normal operation of the existing line is not affected by grouting reinforcement construction, and the reinforcement construction method has the advantages of being low in cost, high in applicability and small in damage.
本发明涉及一种岩溶地区重载铁路既有线加固施工方法，包括以下步骤：对所述既有线进行地下洞体探测，确定加固施工区域；在所述既有线上设置吊轨梁，使所述吊轨梁穿过所有所述加固施工区域；探明并保护所述既有线的光缆和电缆的位置，在所述加固施工区域内布设若干注浆孔组，在所述若干注浆孔处钻孔注浆，注浆完成后，将电缆和光缆恢复至原位，拆除吊轨梁。本发明所述的一种岩溶地区重载铁路既有线加固施工方法，通过设置吊轨梁以及对光缆和电缆进行保护，使注浆加固施工不影响既有线的正常运行，具有成本低、适用性强，破坏小的优点。
