一、工程概况: 1.工程目的及范围: 东南二环支线污水管道是南城污水干线的支线,解决肿瘤医院及附近厂区的污水排放问题,下游接入南城污水干线。 2.主要工程量: φ1550混凝土管:426.61米。φ400～φ1100混凝土预留管14.2米。各种检查井:8座。 3.工程特点: ①施工现场狭小,地面情况复杂,采用顶管施工。11~#～13~#段管线上方是美术红灯厂车间及库房,13~#～14~#段需在民房和旧东南郊灌渠下穿过,施工难度较大。②水文地质及工程地质条件不良,本工
I. Project Overview: 1. Project purpose and scope: The South East Second Ring Road branch sewage pipeline is a branch line of the Nancheng wastewater main line, solving the problem of sewage discharge in the Tumor Hospital and the nearby plant area, and downstream access to Nancheng sewage trunk line. 2. The main amount of work: φ1550 concrete pipe: 426.61 meters. Φ400 ~ φ1100 concrete reserved pipe 14.2 meters. Various inspection wells: 8 seats. 3. Engineering characteristics: 1 The construction site is small and the ground conditions are complex. Above the 11~#~13~# section of the pipeline are the art red light factory workshops and warehouses. The 13~#~14~# sections need to pass under the canals in the houses and the old southeastern suburbs. The construction is difficult. 2 The hydrogeology and engineering geology conditions are poor.
