Device and method for overhauling inner bottom surface of aqueduct

Abstract

The invention provides a device for overhauling an inner bottom surface of an aqueduct. The device comprises: two sets of cofferdam devices, wherein each cofferdam device comprises a framework box body, and first water baffles are arranged on the opposite vertical side faces of the two sets of framework box bodies; a supporting device which comprises two supporting vertical rods, wherein the supporting vertical rods are hinged to the framework box bodies through a plurality of first connecting rods and second connecting rods, and sealing pieces are arranged on the faces, making contact with the inner bottom face of the aqueduct, of the framework box bodies and the second connecting rods; a water-proof device which comprises a first water-proof film and a second water-proof film, wherein the two side edges of the first water-proof film and the two side edges of the second water-proof film are in sealed connection with the two sets of framework box bodies correspondingly, and the bottom edges of the first water-proof film and the second water-proof film are in sealed connection with the second connecting rods correspondingly; a driving device which is used for driving the supporting device to open so that the two cofferdam devices can abut against the two inner side walls of the aqueduct, wherein a construction space is defined by the cofferdam devices and the water-proof device. Water flow of the aqueduct is not completely cut off, transportation and use of the water flow are not affected, and the inner bottom face of the aqueduct can be overhauled.

Description

technical field [0001] The invention relates to the technical field of aqueduct maintenance, in particular to an aqueduct inner bottom maintenance device and maintenance method. Background technique [0002] An aqueduct is an overhead water delivery structure that transports water across river canals, roads, ravines, etc. It is one of the most widely used intersecting building structures in canal building structures. In addition to being used to transport canal water for farmland irrigation, urban domestic water, and industrial water transport across river basins, the aqueduct can also provide drainage and diversion. [0003] During the long-term operation of the aqueduct, cracks on the bottom surface of the aqueduct body, aging of the sealing gasket at the joint of the aqueduct, and damage and falling off of the waterproof coating are prone to occur, which makes the aqueduct prone to water leakage at the cracks. The cumulative risk will eventually lead to the collapse of t...
