Leakproof seal type steel bell and spigot concrete pipe

Abstract

The invention relates to a leakproof seal type steel bell and spigot concrete pipe. Two ends of a concrete pipe are respectively and fixedly provided with a bellmouth steel ring ad a spigot steel ring, wherein the bellmouth steel ring and / or the spigot steel ring are / is radially welded and fixedly connected with a bellmouth water-resisting ring and a spigot water-resisting ring, a waterproof sealant is packaged in a gap between the bellmouth water-resisting ring and the bellmouth steel ring, a waterproof sealant is packaged in a gap between the spigot water-resisting ring and the spigot steel ring, and the bellmouth water-resisting ring and the spigot water-resisting ring are respectively fixedly arranged on the bellmouth steel ring and the spigot steel ring inside the concrete pipe. The provided leakproof seal type steel bell and spigot concrete pipe in the invention has the advantages of strong structural leakage resistance, simple manufacture, and shortened production time, and can effectively enhance the integral sealing property of a pipeline and guarantee the water supply pressure.

Description

technical field [0001] The invention belongs to the field of concrete prefabricated components, in particular to a leakproof and sealed steel socket socket concrete pipe. Background technique [0002] Steel socket concrete pipes have a wide range of calibers and are widely used. With the vigorous development of infrastructure in the country, the demand for water and gas transmission pipelines has greatly increased, especially the application of large steel socket concrete pipes. The structure of the current steel socket concrete pipe is mainly that the two ends of the concrete pipe body are respectively fixed with a steel socket and a steel socket. The long-term hydraulic test found the following problems: In the steel socket concrete pipe compression test, when a certain pressure is applied, water will seep out along the gap between the concrete and the steel socket or the steel socket. According to the test analysis, this kind of leakage will affect the tightness of the o...

The long-term hydraulic test found the following problems: In the steel socket concrete pipe compression test, when a certain pressure is applied, water will seep out along the gap between the concrete and the steel socket or the steel socket. According to the test analysis, this leakage will affect the tightness of the overall pipeline and the water supply pressure
