Aqueduct structure and water-stop belt overhauling construction device and use method thereof

Abstract

The invention discloses an aqueduct structure and water-stop belt overhauling construction device, and relates to the technical field of aqueduct maintenance. The device comprises a fence assembly and a supporting framework; walkway plates are arranged on the two sides of the top of a U-shaped aqueduct, and a cross beam is arranged between the walkway plates; the fence assembly comprises a first coaming, a second coaming, a gate and sealing devices; the gate can rotate around the first coaming and the second coaming in the vertical direction; the sealing devices are located at the bottoms of the first coaming and the second coaming and the contact position of the gate and the U-shaped aqueduct; and each layer of supporting framework comprises a first supporting rod and a second supporting rod. A constructor can descend into the aqueduct to overhaul or maintain the side wall of the aqueduct, and the device is convenient and applicable. The invention further discloses a use method of the aqueduct structure and water-stop belt overhauling construction device.

Description

technical field [0001] The invention relates to the technical field of aqueduct maintenance, and more specifically relates to an aqueduct structure and waterstop maintenance construction device. The invention also relates to the use method of the aqueduct structure and the water stop maintenance construction device. Background technique [0002] The Shahe and Dalang River aqueducts of the South-to-North Water Diversion Project are concrete U-shaped aqueducts. At the same time, the U-shaped aqueduct is an overhead water delivery structure that transports water across river canals, roads, and ravines. It is one of the most widely used cross building structures in canal system structures 1. U-shaped aqueducts are not only used to transport canal water for farmland irrigation, urban domestic water, and industrial water transport across river basins, but also provide drainage and diversion. [0003] During the long-term operation of the U-shaped aqueduct, the gasket at the joint...

AI Technical Summary

Problems solved by technology

[0003] During the long-term operation of the U-shaped aqueduct, the gasket at the joint of the aqueduct is prone to aging and damage, resulting in water leakage at the joint of the U-shaped aqueduct. The aqueduct connection collapses, once an accident occurs, it will cause major economic losses and social impact

[0004] At present, in the maintenance of the side wall of the aqueduct, the water cutoff treatment is usually carried out, that is, the main gate upstream of the aqueduct is closed to ensure that the water in the aqueduct does not flow, and then the construction device is put into the aqueduct for maintenance or maintenance. The width of the aisle slab is smaller than the width of the aqueduct body. At the same time, there are multiple beams at intervals on the aisle plate of the U-shaped aqueduct, and the distance between two adjacent beams is only 1-2m. In the aqueduct, it is impossible to use the construction device to isolate the anhydrous construction space in the aqueduct joint area, thus restricting the construction personnel from entering the aqueduct for maintenance or maintenance
