- 摘要:
- 以泸州市二环路综合管廊为例，分析了浅丘地形下多舱管廊的设计要点。依据规划用地性质、道路沿途障碍物分布及设计坡度等因素，确定了管廊线位走向，明确了玉杨路-渔子溪路为污水管线入廊段。通过分析入廊管线的种类及数量，明确了管廊标准断面分为综合舱、高压电力舱、燃气舱及污水舱四个舱室，且确定了各舱室布局和断面尺寸。通过分析浅丘地形障碍物的特点，提出了采用多级倒虹的形式避让深、宽大断面下穿隧道；采用管廊桥的形式避让下穿隧道、河流及绿道的连续障碍物；采用“上游出舱-减小坡度通过障碍物-跌水降低标高-接入下游”的形式，有效解决管廊污水管线入廊段与直埋段的衔接问题。
- Abstract:
- Taking the Erhuan Road utility tunnel in Luzhou as an example, the design key points of multi-compartment utility tunnel in shallow hill terrain were analyzed. According to the property of planning land usage, the distribution of obstacles along the road and the design slope and other factors, the line direction of the utility tunnel was determined, and the wastewater pipeline in the utility tunnel from Yuyang Road to Yuzixi Road was defined. By analyzing the types and quantity of pipelines, it was clear that the standard section of utility tunnels was divided into four compartments, namely, comprehensive cabin, high voltage power cabin, gas cabin and wastewater cabin. Meanwhile, the layout and the section size of each compartment were determined. Based on the analysis of the characteristics of shallow hill terrain obstacles, a multi-stage inverted siphon was proposed to avoid the tunnel with deep and wide section. The form of utility tunnel bridge was adopted to avoid continuous obstacles of tunnel, river and greenway. By adopting the form of “upstream cabin exit-reducing slope to pass through obstacles-dropping water to lower elevation-accessing downstream”, the connection problem between the tunnel section and the buried section of the wastewater pipeline was effectively solved.
