A kind of aqueduct inner bottom surface maintenance device and maintenance method

Abstract

The invention proposes a maintenance device for the inner bottom surface of an aqueduct, which includes two sets of cofferdam devices, the cofferdam devices include skeleton boxes, and a first water baffle is arranged on the opposite vertical side of the two sets of skeleton boxes; the supporting device , including two supporting vertical rods, each supporting vertical rod and the skeleton box are hingedly connected by a number of first connecting rods and second connecting rods, and the side of the skeleton box body and the second connecting rod that is in contact with the inner bottom surface of the aqueduct Seals are arranged on the upper part; the water barrier device includes a first water barrier film and a second water barrier film, the two sides of the first water barrier film and the second water barrier film are respectively sealed with the two groups of skeleton boxes, and the second water barrier film is sealed. The bottom edges of a water-proof membrane and the second water-proof membrane are respectively connected with the second connecting rod in a sealed connection; the driving device is used to drive the supporting device to open so that the two groups of cofferdam devices can abut the two inner side walls of the aqueduct and make the cofferdam The installation and water isolation device enclose the construction space. The invention does not completely cut off the water flow of the aqueduct, does not affect the transportation and use of the water flow, and can repair the inner bottom surface of the aqueduct.

Description

technical field [0001] The invention relates to the technical field of aqueduct maintenance, in particular to an aqueduct inner bottom surface maintenance device and a maintenance method. Background technique [0002] Aqueduct is an overhead water conveyance building structure that conveys water flow across rivers, roads, ravines, etc. It is one of the most widely used cross-building structures in canal building structures. In addition to transporting canal water for farmland irrigation, urban domestic water, and industrial water transport across river basins, aqueducts can also provide drainage and diversion. [0003] During the long-term operation of the aqueduct, cracks on the inner bottom surface of the aqueduct body, aging of the gaskets at the joints of the aqueduct, and damage to the waterproof coating, etc., make the aqueduct prone to water leakage at the cracks. Accumulated risks will eventually lead to the collapse of the aqueduct at the crack, and in the event of...
