Abstract

The invention discloses an underground water pipeline with built-in restricting conical chamfered blocks. The underground water pipeline comprises a pipeline body, wherein the pipeline body is paved under the ground, the two ends of the pipeline body communicate, a plurality of conical chamfered blocks are arranged on the pipeline wall of the upper end of the pipeline body, the upper ends of the conical chamfered blocks are fixed to the pipeline wall of the upper end of the pipeline body, restrictor plates which are tilted inwards, drawn closer and crossed are arranged at the two ends of the conical chamfered blocks, and dripping pipes are mounted at the bottom conical corner parts of the conical chamfered blocks. Through the mode, restriction protection can be carried out on the underground water pipeline. Water flow can be controlled when water flow in the underground water pipeline is too large, and water flow is prevented from being too large, applying certain pressure on the water pipeline and enabling the water pipeline to burst.

Description

technical field [0001] The invention relates to the field of underground water pipelines, in particular to an underground water pipeline with built-in conical chamfering blocks for flow restriction. Background technique [0002] Underground pipelines are pipelines laid underground for transporting liquids, gases or loose solids, mostly for transporting liquids for discharge. There are many types of modern underground pipelines, including circular, oval, semi-elliptical, multi-circular, oval, rectangular, horseshoe-shaped and other cross-sectional forms, using steel, cast iron, concrete, reinforced concrete, prestressed concrete, brick, Stone, asbestos cement, clay, plastic, fiberglass and other materials. However, in some cases, the excretion is too large, and the strength of the underground pipeline is not up to the requirement, and it is easy to be damaged by a large pressure, which reduces the service life of the underground water pipeline. Contents of the invention ...
