Abstract

A device for simulating a leakage condition of a crack of a water supply pipeline in soil is provided by the invention. The invention aims to solve a technical problem of low leakage simulation experiment precision due to a condition that actual leakage condition of a crack wholly wrapped with water, namely, a crack of an urban water supply pipeline network, cannot be simulated in a prior laboratory when studying pipeline network leakage. The device is composed of a water supply pipe, a rubber sheet, an iron sheet, a hoop, an exhaust pipe and an adjuster. The water supply pipe is provided witha first crack. The rubber sheet is provided with a second crack. The iron sheet is provided with a through hole communicating with a round table shaped pipeline. The rubber sheet covers the first rack in the water supply pipe and the iron sheet covers the second crack in the rubber sheet. The hoop fixes the iron sheet, the water supply pipe and the rubber sheet together. The exhaust pipe communicates with a free end of the round table shaped pipeline. The adjuster sleeves the exhaust pipe. The device provided by the invention improves the simulation precision by 90% or more.

Description

technical field [0001] The invention relates to a device for simulating leakage at cracks of water supply pipelines. Background technique [0002] In reality, the leaked water from cracks in water supply pipes will scour and erode the soil, so that the cracks are not in direct contact with the soil. When the laboratory studies the leakage of the pipe network, there is no method for accurately simulating the actual cracks. The method of directly draining the cracks or wrapping the cracks with soil is often used, which fails to simulate the actual leakage of the cracks in the urban water supply pipe network such as "water-filled pipes". Therefore, it cannot truly reflect the corrosion morphology and water leakage at the cracks, and reduce the accuracy of leakage simulation experiments. Contents of the invention [0003] The present invention aims to solve the technical problem that the existing laboratory cannot simulate the actual leakage situation of cracks in the urban w...
