AI Technical Summary

Benefits of technology

This patented technology helps reduce noise from drains during building operations while also improving their durability against damage caused by external factors such as rain or snow falling down onto them overnight. It can be applied evenly across different types of materials used for constructings like concrete slabs that are installed inside walls with dirt roads.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency and safety of draining systems used on urban areas due to their use of long pipeline networks that lead to odors from wastewater mixing with other materials or being placed near roadsides during construction activities.

Abstract

The invention relates to the technical field of pipeline construction and provides a water supply and discharge project pipeline laying method for the problem of influence on traffic. The technical scheme is as follows: the water supply and discharge project pipeline laying method comprises the following steps: S1, excavating construction wells; S2, drilling and excavating a pipeline mounting hole: drilling and excavating the pipeline mounting hole for communicating the adjacent construction wells through drilling and excavating equipment, wherein the hole diameter of the pipeline mounting hole is more than the inner diameter of a designed water discharging pipe; S3, mounting a water discharging pipe: coating the hole wall of the pipeline mounting hole with a water discharging pipe composition and forming the water discharging pipe after the water discharging pipe composition is solidified; and S4, performing water discharging pipe surface treatment: coating the inner wall of the waterdischarging pipe with a protective layer composition and forming a protective layer after the protective layer composition is solidified. The construction wells are excavated and the pipeline mounting hole is drilled and excavated, so that large-area ground excavation is not needed when the water discharging pipe is mounted and influence on urban traffic is reduced.
