Expressway excavation section medial strip drainage structure and construction method
The invention discloses a drainage structure for a medial strip of an excavation section of an expressway and a construction method. The drainage structure comprises the medial strip excavated on a road surface and a roadbed and a drainage and storage blind ditch connected with the medial strip through a transverse drainage pipe. A one-cloth one-film and cement mortar plastering layer, a zeolite layer and a longitudinal diaphragm plate are arranged in the water drainage and storage blind ditch; the construction method comprises the following steps: constructing a water drainage and storage blind ditch below the greening crushing platform; a transverse drainage pipe is pre-buried in the roadbed section, and two ports of the transverse drainage pipe are connected with the water drainage and storage blind ditch and the central separation strip respectively; and after the cement-stabilized base layer of the pavement is completed, anti-seepage treatment is conducted on the medial strip. Accumulated water in the medial strip can be effectively drained, and pavement diseases caused by long-time retention of water in a pavement structure layer are reduced; meanwhile, due to the arrangement of a water drainage and storage structure, the survival rate of green plants on highways in northern arid areas can be effectively increased, visual fatigue caused by long-distance driving is relieved, and the driving safety risk is reduced.
本发明公开了一种高速公路挖方段中央分隔带排水结构及施工方法，包括开挖在路面和路床上的中央分隔带，以及通过横向排水管与中央分隔带连接的排蓄水盲沟；排蓄水盲沟内设有一布一膜+水泥砂浆抹面层、沸石层、纵向横隔板；施工时包括：在绿化碎落台的下方施工排蓄水盲沟；在路床段预埋横向排水管，并将横向排水管两端口分别与排蓄水盲沟、中央分隔带连接；待路面的水稳基层完成后，对中央分隔带进行防渗处理。本发明可以有效的排除中央分隔带内的积水，减少因为水长时间滞留在路面结构层内引起的路面病害；同时由于设置了排蓄水结构，可以有效的提高北方干旱地区高速公路绿化植物的成活率，缓解长途开车引起的视觉疲劳，降低行车安全风险。
