Leakage-preventing steel bell and faucet concrete pipe

Abstract

The invention relates to a leakage-preventing steel bell and faucet concrete pipe. Both ends of a concrete pipe body are respectively and fixedly provided with a bell steel ring and a faucet steel ring, wherein a bell water-blocking ring is radially and fixedly arranged on the bell steel ring, a faucet water-blocking ring is radially and fixedly arranged on the faucet steel ring, and the bell water-blocking ring and the faucet water-blocking ring are respectively and fixedly arranged on the bell steel ring and the faucet steel ring in the concrete pipe. The leakage-preventing steel bell and faucet concrete pipe has the advantages of scientific and reasonable structural design, simple fabrication, strong leakage prevention and lower cost and is a leakage-preventing steel bell and faucet concrete pipe capable of effectively enhancing the integral tightness of a pipeline and ensuring the water supply pressure.

Description

technical field [0001] The invention belongs to the field of concrete prefabricated components, in particular to a leak-proof steel socket socket concrete pipe. Background technique [0002] With the vigorous development of infrastructure in the country, the demand for water and gas pipelines has greatly increased, especially large-scale steel socket concrete pipes are widely used. 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 overall pipeline and the water supply pressure. Contents of the invention [0003] The purpose of...
