A pavement retaining drainage system at the opening of the central divider in super-high road sections

Abstract

The invention discloses a pavement drainage system at the opening of the central divider of a super-elevated road section, comprising a road water-retaining belt, which is arranged at the opening of the central divider of a super-high road section to divert and drain road water; the road water-retaining belt It is connected with the water collection well, the water collection well is connected with the water outlet well through the drainage pipe, the water outlet well is connected with the side ditch through the horizontal drainage pipe, and the pavement water retaining belt drains the road surface water to the water collection well, and then is discharged to the side through the water outlet well and the horizontal drainage pipe. ditch.

Description

technical field

[0001] The invention belongs to the technical field of drainage of expressways and first-class highways, and in particular relates to a pavement retaining and drainage system at the opening of the central divider of a superhigh road section. Background technique

[0002] At present, the pavement drainage method of the central divider of the superelevation section of high-grade highways at home and abroad, according to the rainfall and the width of the pavement, adopts a scheme of draining through the inner pavement or setting up underground drainage facilities.

[0003] 1. In areas where the annual precipitation is less than 400mm, two-way four-lane roads can be provided with an open channel scheme in the middle zone, and the road surface water flows through the inner side of the road surface to be discharged.

[0004] 2. In areas where the annual precipitation is greater than 400mm, or where there are more than four lanes, the outer road surface water should...
