Expressway reconstruction and extension project construction period road surface drainage system

Abstract

The invention discloses an expressway reconstruction and extension project construction period road surface drainage system. The road surface drainage system includes: torrent grooves which are formedin a side slope of an old road; drainage channels which are fixedly arranged in a bottom basic layer of a newly expanded road, wherein each drainage channel includes a water inlet end fixedly connected to a tail end of the corresponding torrent groove, and a water outlet end opposite to the water inlet, a plurality of drainage channels are arranged, and the plurality of drainage channels are arranged in parallel; communication pipes arranged between every two adjacent drainage channels and for communicating with every two adjacent drainage channels; a water collection tank which includes a cleaning device and a water storage box, and is used for collecting water on the road surface, cleaning the water, and reusing the water; and a temporary drainage groove having a cross section of a U-shaped structure, wherein the temporary drainage groove is arranged outside a roadbed of the newly constructed road, can lead water on the road surface of the old road and gathered water on a construction site to the water collection tank during construction, the drained water can be collected and reused, and smooth construction of a new road can be achieved.

Description

technical field [0001] The invention relates to the field of expressway reconstruction and expansion projects, and more specifically, the invention relates to a road surface drainage system during the construction period of expressway reconstruction and expansion projects. Background technique [0002] With the advancement of science and technology and the rapid development of the economy and society, people's living standards continue to improve, and high-speed travel is becoming more and more frequent. It is necessary to expand road traffic capacity to meet people's travel needs. Expansion on the basis of the original expressway lane not only saves cost, but also tests the technology. Due to the low rapid drainage capacity of the expressway, when heavy rainfall occurs during the construction period, a large amount of water will appear on the road surface of the expressway. Timely discharge will greatly affect the construction progress. It can be seen from this that it is ...
