Description
Technical Field
The invention relates to a fog system, in particular to a method for anti-freezing and anti-compression laying of an underground water supply pipeline of the fog system.
Background
The misten system is a water atomization system which generates superfine mist particles (more than 70 percent of the diameter is less than 4 microns) through high-pressure micropores. The atomized fine fog particles have the functions of cooling and humidifying, dust suppression and rich negative oxygen ions, and are widely applied to occasions such as urban buildings, garden landscapes, stage effects and the like.
In the existing water supply pipeline of the fog system, the underground laying method comprises the steps of ditching along a green belt, a flower bed or a road edge, then placing a water pipe and backfilling original soil to directly lay, wherein the laying depth of the water pipe is about 600 mm. Because the green belt, the flower bed and the road edge are areas which are easy to accumulate water, the temperature is reduced in winter in northern areas of China, water in the water pipe is easy to freeze into ice, and the water supply of the mist system is interrupted, so that the mist system cannot work. Meanwhile, the water supply pressure of the fog system is very high, usually 5 to 7MPa, and the fog system is directly buried in a green belt, a flower bed or a road edge area, so that the water supply pipeline leaks due to crushing and vibration damage of mechanical equipment for road facility maintenance operation.
Disclosure of Invention
The invention aims to provide a frost-resistant and pressure-resistant laying method for an underground water supply pipeline of a fog-sen system, so as to ensure reliable water supply of the underground water supply pipeline of the fog-sen system.
In order to achieve the purpose, the invention can adopt the following technical scheme:
the invention discloses a freeze-proof and compression-proof laying method of an underground water supply pipeline of a fog system, which comprises the following steps of
step 4, paving a layer of perlite on the plain concrete layer to embed a water supply pipe in the plain concrete layer, wherein the water supply pipe is embedded in the geometric center of the perlite layer; the perlite layer is used for preserving heat, preventing heat transmission and preventing the interior of the water supply pipe from being frozen;
and 8, arranging a water pipe warning belt on the concrete cover plate, backfilling the original soil to the height of the road surface, and arranging water pipe warning piles.
Preferably, in step 4, the upper surface of the perlite layer is arched, so that the geotextile which is crossed and rolled on the upper surface of the perlite layer is matched with the perlite layer to further improve the water seepage prevention capability.
Preferably, in step 5, the left edge of the geotextile which is crossed and drawn on the upper surface of the perlite layer extends to the right side wall of the laying ditch, and the right edge extends to the left side wall of the laying ditch.
The invention is specially designed for laying the underground water supply pipeline of the fog-sen system, solves the problems of no frost resistance and no pressure resistance of the underground water supply pipeline of the fog-sen system due to the influence of the environment, and ensures that the fog-sen system can still normally work in northern areas and high-altitude areas of China.
