A k-shaped joint of water supply pipeline with emergency self-recovery ability

Abstract

The invention relates to a water supply line K-shaped joint with emergency self-recovery capability. The water supply line K-shaped joint with the emergency self-recovery capability consists of a K-shaped mechanical joint, shape memory alloy bolts, a vibrating wire strain sensor, a power outgoing line, a data outgoing line and a data processing and emergency reaction integration box, wherein a bellmouth and a socket of the K-shaped mechanical joint are sealed and mounted in place; the shape memory alloy bolts which replace common bolts are connected with the K-shaped mechanical joint; and the vibrating wire strain sensor is arranged on one of the bolts and monitors strain of the bolt. The data processing and emergency reaction integration box is mounted; two power lines are led out from a high-power power supply in the data processing and emergency reaction box and are connected to two ends of each shape memory alloy bolt; and moreover, a data line is led out from the data processing and emergency reaction box and is connected with the vibrating wire strain sensor. When the violent earthquake occurs, the K-shaped pipeline joint can be loose and can even be separated from a water supply line, the strain of the shape memory alloy bolts is increased sharply, and the vibrating wire strain sensor records a strain value and transmits the strain value to the data processing and emergency reaction integration box.

Description

technical field [0001] The invention belongs to the field of water supply pipeline engineering in municipal engineering, and specifically relates to a K-shaped joint of a water supply pipeline with emergency self-recovery capability. Background technique [0002] The water supply pipeline is the main part of the urban water supply network, which is mainly buried underground. The destruction of these pipelines will not only lead to the economic loss of the pipeline itself, but more seriously, it will lead to the loss of urban regional functions. During the strong earthquakes that have occurred around the world in the past two decades, the urban water supply pipelines have been severely damaged, which has brought serious difficulties to post-disaster rescue and relief, post-disaster industrial production and residents' lives. The repair of the pipe network after the earthquake also needs to invest a lot of money. [0003] The water supply pipeline usually adopts a socket-typ...
