Anti-freezing and pressure-resistant laying method for underground water supply pipeline of fog and forest system

Abstract

The invention discloses an anti-freezing and pressure-resistant laying method for an underground water supply pipeline of a fog and forest system. The method comprises the steps that 1, a laying ditch is excavated; 2, geotextile is laid along the ditch bottom of the laying ditch, the left and right sides of the geotechnical cloth extend upwards along the corresponding side walls attached to the laying ditch; 3, a layer of plain concrete is laid on the geotechnical cloth; 4, a layer of perlite is laid on the plain concrete layer, and the water supply pipe is buried in the perlite; 5, the left edge and the right edge of the geotechnical cloth are crosswise rolled on the upper surface of the perlite layer; 6, the geotechnical cloth crosswise rolled on the upper surface of the perlite layer is covered with a layer of pseudo-ginseng composite soil; 7, a concrete cover plate is paved on the upper surface of the pseudo-ginseng composite soil layer; and 8, a water pipe warning belt is arranged on the concrete cover plate, then undisturbed soil is backfilled to the height of the road surface, and a water pipe warning pile is arranged. The anti-freezing and pressure-resistant laying method is specially designed for laying the underground water supply pipeline of the fog-forest system, the problem that the underground water supply pipeline of the fog-forest system is not resistant to freezing and pressure due to environmental influence is solved, and it is guaranteed that the fog-forest system can work normally in northern areas and high-altitude areas.

Description

technical field [0001] The invention relates to a fog forest system, in particular to an anti-freeze and pressure-resistant laying method for an underground water supply pipeline of the fog forest system. Background technique [0002] The Wusen system is a water atomization system that generates ultra-fine mist particles (more than 70% of the diameter is less than 4 microns) through high-pressure micropores. The atomized fine mist particles have the function of cooling and humidifying and dust suppression, and are rich in negative oxygen ions. They are widely used in urban buildings, garden landscapes, stage effects and other occasions. [0003] The existing water supply pipeline of the Wusen system is laid underground by digging trenches along the green belt, flower bed or roadside, and then laying the water pipe backfilling the undisturbed soil for direct laying. The depth of the water pipe laying is about 600mm. Since green belts, flower beds and roadsides are areas that...

AI Technical Summary

Problems solved by technology

Since green belts, flower beds and roadsides are areas that are prone to water accumulation, the temperature in northern my country is lower in winter, and the water in the water pipes is easy to freeze into ice, causing the water supply of the fog forest system to be interrupted and unable to work.

At the same time, because the water supply pressure of the Wusen system is very high, usually 5MPa to 7MPa, it is directly buried in the green belt, flower bed or roadside area, and there is a phenomenon that the water supply pipe is leaking due to the mechanical equipment of the road facility maintenance operation.
