Rainwater Harvesting and Utilization System during Construction Period of Expressway Reconstruction and Expansion Project

Abstract

The invention discloses a rainwater collection and utilization system for a construction period of a highway reconstruction and extension project. The rainwater collection and utilization system comprises a water collection pond, a water discharging tank connected to the water collection pond via a first pipeline, a filter device, a purifying pool connected to the water collection pond via a second pipeline, a spraying device connected to the purifying pool via a third pipeline and a control device, wherein the two side walls of the water discharging tank are provided with interception hooks;the filter device includes a hollow fixing shaft, a hollow telescopic shaft, a sieve net and a supporting rod; a fine sand purifying layer is formed in the purifying pool; a water outlet is formed inthe bottom of the purifying pool; the spraying device has a main pipe, a branch pipe and a spraying nozzle; the spraying nozzle has a connection rod and a spraying disc; and the control device is formed by a motor and a controller. Rainwater is collected and processed, and sprayed on the construction site to reduce dust, so construction site environment can be maintained and construction worker health can be guaranteed; and water resource can be saved.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for construction highways, in particular to a rainwater collection and utilization system during the construction period of highway reconstruction and expansion projects. Background technique [0002] With the rapid development of the national economy, the construction of expressways in our country is very rapid. Due to the constraints of social and economic level, technical level and construction ideas at the time of construction, most of the expressways that have been built and used are two-way four-lane expressways, and the proportion of six-lane and eight-lane expressways is relatively low. At present, a considerable part of them can no longer meet the requirements of traffic growth and social development, and there is an urgent need to expand road traffic capacity. However, in the process of expressway reconstruction and expansion, a large amount of dust pollution will be caused,...

Problems solved by technology

At present, a considerable part of them can no longer meet the requirements of traffic growth and social development, and there is an urgent need to expand road traffic capacity

However, in the process of reconstruction and expansion of the expressway, a large amount of dust pollution will be caused, which will not only endanger the health of the construction workers on the site, but also cause harm to the surrounding residents and passers-by.

At present, most construction sites use artificial dust reduction, directly connected to tap water pipes, and spray the construction site. However, as we all know, my country is in a state of water shortage. One-fourth of the occupied amount, because each region is in different hydrological zones and affected by monsoon climate, water resources are not compatible with land, mineral resources distribution and industrial water structure, water pollution is serious, and the lack of water quality exacerbates the shortage of water resources

Moreover, the use of artificial spraying not only consumes a lot of water, but also has an unsatisfactory dust reduction effect.
