Construction technology of underground diaphragm wall below line pipe
The invention discloses a construction technology for an underground diaphragm wall below a line pipe. The construction technology specifically comprises the following steps that construction preparation is conducted; groove expanding excavation is conducted; the outer side of the cable is wrapped with reinforced concrete, and a steel truss is hoisted; thick steel plates wrap the periphery of the cable duct bank, and H-shaped steel beams are connected to the outer walls of the steel plates on the upper side; guide wall construction is carried out around the cable, and a warning mark is arranged at the top of a guide wall; manufacturing a reinforcement cage; a trenching machine carries out trenching excavation construction; and hoisting and placing a reinforcement cage, installing a guide pipe and pouring concrete. On the basis that the grab bucket of the trenching machine excavates on the two sides of the electric wire and cable vertically, the excavation width is increased through the detachable expanding excavation bucket teeth, so that excavation of the soil body under the influence range of the high-voltage cable is achieved, one-groove double-cage construction is adopted, high-voltage cable protection and underground diaphragm wall splicing construction are well completed, and the construction efficiency is improved. High-voltage cable relocation is avoided, the construction investment is reduced, and the construction period is shortened.
本发明公开了一种线管下方的地下连续墙施工工艺，具体包括以下步骤：施工准备；进行扩槽开挖；对电缆外侧进行钢筋混凝土外包及吊装钢桁架；在电缆排管四周包裹厚钢板，上侧两侧钢板外壁均连接H钢梁；在电缆周边进行导墙施工，导墙顶部设置警示标志；钢筋笼制作；成槽机进行成槽开挖施工；进行钢筋笼吊装安放和导管安装及混凝土灌注。本发明在成槽机抓斗在电线电缆两侧直上直下开挖的基础上，通过可拆卸的扩挖斗齿，增加开挖宽度，从而实现高压电缆影响范围正下方土体开挖，通过采取一槽双笼施工，较好的完成高压电缆保护及地下连续墙拼幅施工，避免高压电缆迁改，减少了建设投资，节约了工期。
