Problems solved by technology
Since the aqueduct section is not allowed to cut off the water, the conventional maintenance measures are only some consolidation and grouting reinforcement and repairs outside the aqueduct, which cannot completely solve the maintenance and maintenance problems at the connection joints inside the aqueduct, and cannot meet the engineering needs

The invention proposes a side wall maintenance device and maintenance method for an aqueduct under the condition of continuous water, including a cofferdam device, two groups are symmetrically arranged, the cofferdam device includes a skeleton box, and one of the skeleton boxes is vertical The side and bottom are respectively used for sealing against the inner side wall and inner bottom of the aqueduct, and the other three vertical sides of the skeleton box are provided with water baffles; the driving device includes the reaction force frame, support components and hydraulic components , the reaction force frame is arranged on the aisle board where the top surface of the aqueduct is located, the hydraulic components are arranged on the reaction force frame, the support components are respectively connected with the two groups of cofferdam devices, and the hydraulic components are used to drive the support components to spread so that the two groups of enclosures can be opened. The weir device seals the two inner side walls of the aqueduct respectively. The two sets of cofferdam devices of the present invention can seal both sides of the aqueduct at the same time. The cofferdam device does not completely stop the water flow of the aqueduct, and does not affect the transportation and use of the water flow. .
Description
technical field [0001] The invention relates to the technical field of aqueduct maintenance, in particular to a sidewall maintenance device and a maintenance method for aqueducts under the condition of continuous water. Background technique [0002] Aqueduct is an overhead water conveyance building structure that conveys water 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 in the side walls of the aqueduct, aging of the gaskets at the joints of the aqueduct, and damage to the waterproof coating, etc., will cause water leakage at the joints of the aqueduct. The accumulated risk will eventually lead to the collapse of the aqueduct connection, which ...
