Abstract

The invention discloses a ring-type bridge pile foundation scour monitoring system and a monitoring method thereof. The ring-type bridge pile foundation scour monitoring system comprises a bridge pilefoundation, a carrying device, sensors and a data processing system; a group of linear tracks are arranged in the circumferential direction along the exterior wall surface of the bridge pile foundation; the carrying device is matched with the linear tracks in a sliding manner; the carrying device comprises a carrying round ring and a group of trundles arranged on the carrying round ring; the sensors are arranged on the surface of the carrying round ring and the bridge pile foundation; and the data processing system is fixed at the top part of the bridge pile foundation and connected with thesensors through conductors for receiving data in the sensors. The invention has the beneficial effect that the ring-type bridge pile foundation scour monitoring system and the monitoring method thereof are applicable for the installation of the bridge pile foundation scour monitoring system and the real-time monitoring to pile foundation scour when in construction.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a ring-type bridge pile foundation scour monitoring system and a monitoring method thereof. Background technique [0002] Local scour is a natural phenomenon caused by the erosion of the alluvial seabed. The scour of the bridge foundation includes the scour of bridge piers and bridge piles, and the resulting bridge damage often occurs. The water damage of bridge pile foundation caused by local scour is sudden and destructive, which will cause great loss to people's life and property. Kandasamy and Melville (1998) showed that 6 out of 10 bridge damages caused by Hurricane Bola in New Zealand were related to pier scour. Macky (1990) pointed out in the research report submitted to the New Zealand Department of Science and Industrial Research (DSIR): DSIR spent about 50% of its total expenditure on bridge repair and maintenance, of which the cost of bridge pier scour repair acco...
