Integral water-stopping lantern ring for concrete pipeline joints

Abstract

The invention relates to a water-stopping and buffering device for concrete pipeline joints, in particular to an integral water-stopping lantern ring for the concrete pipeline joints. The integral water-stopping lantern ring comprises a buffering plate, a connecting ring and a water-stopping ring and is characterized in that the buffering plate and the water-stopping ring are connected into a whole through the connecting ring. In the use process, compression teeth of the water-stopping ring are extruded and become deformed, the inner side of the water-stopping ring tightly covers the outer wall of a concrete pipeline insertion mouth, and the outer side of the water-stopping ring is closely attached to the inner wall of a pipeline bell end. The connecting ring, the buffering plate and the water-stopping ring cover ports of concrete pipe sections for forming a closed structure and act together for filling gaps between adjacent concrete pipe ends and pipe walls, underground water is prevented from entering pipelines, and water in the pipelines can be prevented from seeping into the ground. The integral water-stopping lantern ring is easy, convenient and fast to install and overcomes the shortcomings that existing water-stopping rings are easily rolled and twisted.

Description

Technical field: [0001] The invention relates to an underground concrete pipeline, in particular to a water-blocking collar for the joint of the concrete pipeline. Background technique: [0002] Modern cities are inseparable from underground pipes. Most underground pipes use reinforced concrete pipes, such as sewage pipes, rainwater pipes, and outer casings for communication, electricity, and gas pipes. Each pipeline is composed of many concrete pipe joints, and the adjacent concrete pipe joints are mostly connected by socket-socket, and rubber plates and rubber rings are arranged between the pipe joints. [0003] The rubber plate pad is between the end faces of the two adjacent concrete pipe joints to prevent the pipe mouth from being broken due to the hard collision of the concrete pipe joints, which is called a buffer plate; a rubber ring is installed on the side wall of the pipe joint port, and the shirt is placed on the Between the inner wall of the pipe joint socket a...

Problems solved by technology

If the ellipticity of each pipe joint is accurately measured and installed in pairs, water leakage can be reduced, but the construction efficiency will be greatly reduced and the construction cost will be increased; if the processing accuracy of the concrete pipe is improved, the ellipticity error can be reduced, then Greatly increase the production cost; if the water blocking ring is thickened, the water blocking ring will roll over and a larger gap will appear when it is installed at the opposite end
