Problems solved by technology

[0003] The total amount of precipitation in the northern arid area is small throughout the year, but due to climate reasons, there may be seasonal heavy precipitation. If no drainage structure is installed inside the ridge line of the road around the island, a large area of ​​accumulation will easily occur near the lowest point of the road longitudinal section. Water not only affects driving safety, but also easily causes water damage to pavement structures
[0004] At present, the common way of drainage around the island is to set a rainwater outlet inside the ring road, and the rainwater will be discharged into the rainwater pipe through the rainwater outlet. This method has a short drainage path. During heavy rainfall, the drainage pressure is relatively high, and the rainwater is not fully utilized.

Embodiment Construction

[0027] The present invention will be further described below in conjunction with drawings and embodiments.

[0028] Such as Figure 1 to Figure 4 As shown, a spiral water storage and drainage structure at a roundabout in an arid area, including a water storage well 3 located in the center of the roundabout, openings distributed circumferentially on the outer ring of the station stone 4, and a spiral drainage ditch 1 located on the roundabout, radial Drainage ditch 2, integrated pump station 5, drip irrigation branch pipe and nozzle 6, the head end of the spiral drainage ditch 1 is connected to the opening at the lowest point of the longitudinal section of the ring road, and the tail end spirally extends inward with a certain slope to the water storage well 3 The head end of the radial drainage ditch 2 communicates with the other corresponding openings, and the tail end extends radially with a certain slope until it communicates with the spiral drainage ditch 1. Both the spiral...

Abstract

The invention discloses an arid region roundabout spiral water storage and drainage structure and a construction method thereof. The structure comprises a water storage well located in the center of a roundabout, openings distributed in the circumferential direction of the outer ring of a standing stone, and spiral drainage ditches, radial drainage ditches, an integrated pump station, drip irrigation branch pipes and nozzles which are arranged on the roundabout, the head ends of the spiral drainage ditches communicating with the opening located at the lowest position of the longitudinal section of a loop, the tail ends of the spiral drainage ditches spirally extend inwards at a certain gradient to communicate with the water storage well, the head ends of the radial drainage ditches communicate with the other corresponding openings, the tail ends of the radial drainage ditches extend in the radial direction at a certain gradient to communicate with the spiral drainage ditches, the spiral drainage ditches and the radial drainage ditches are filled with broken stones, permeable geotextile is laid on the top faces, filter screens are arranged at the head ends, the filter screens are arranged at the tail ends of the spiral drainage ditches, and the inlet end and the outlet end of the integrated pump station are connected with the water storage well, the drip irrigation branch pipes and the nozzles respectively. According to the arid region roundabout spiral water storage and drainage structure and the construction method thereof, the problem of road surface water accumulation after seasonal heavy rainfall can be prevented, and secondary utilization of rainfall can be realized.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a spiral storage and drainage structure of a roundabout in an arid area and a construction method thereof. Background technique [0002] A roundabout is a form of intersection that is used to organize and channelize traffic with a ring road when multiple roads converge. In order to ensure that the vehicle does not slip laterally due to centrifugal force when driving on the ring road, the ring road arch cross slope is generally designed as a double-sided slope. [0003] The total amount of precipitation in the northern arid area is small throughout the year, but due to climate reasons, there may be seasonal heavy precipitation. If no drainage structure is installed inside the ridge line of the road around the island, a large area of ​​accumulation will easily occur near the lowest point of the road longitudinal section. Water not only affects driving safety, ...
