Integrated overhauling device and overhauling method for inner surface of aqueduct

Abstract

The invention provides an integrated overhauling device and overhauling method for an inner surface of an aqueduct, the device comprises two sets of cofferdam boxes which are symmetrically arranged, wherein each cofferdam box comprises two first baffles which are parallel to each other and are vertically arranged, a second baffle is connected between the vertical side edges of the two first baffles, the side edges, away from the second baffles, of the first baffles are used for abutting against the inner side wall of the aqueduct for sealing, and communicating windows are formed in the lower portions of the second baffles. a communicating box body which is of an inverted-U-shaped structure, wherein the two ends of the communicating box body are movably inserted into the connecting windows of the two cofferdam boxes correspondingly and are connected in a sealed mode; a driving device which comprises a supporting assembly and a hydraulic element, wherein the hydraulic element is used for driving the supporting assembly to be opened so that the two cofferdam boxes and the communicating box body can move relatively and conduct enclosure sealing on the inner surface of the aqueduct. Integrated overhauling of the inner side wall and the bottom face of the aqueduct can be achieved through one overhauling device, and the overhauling device is simple in structure and high in overhauling efficiency.

Description

technical field [0001] The invention relates to the technical field of aqueduct maintenance, in particular to an aqueduct inner surface integrated 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, it is easy to have cracks on the inner surface of the aqueduct body, the aging of the gasket at the joint of the aqueduct, and the breakage of the waterproof coating. The cumulative risk will eventually lead to the collapse of the aqueduct at the cracks, and once an accident occurs, it will ca...

AI Technical Summary

Problems solved by technology

Under the condition of uninterrupted water, only a certain construction space can be enclosed in the aqueduct through specific maintenance equipment, and the construction space can only be repaired to specific surfaces in the aqueduct, such as only the inner wall or inner bottom of the aqueduct. However, the reality is that the connecting joints of the aqueduct exist on the inner wall and inner bottom of the aqueduct, and they need to be overhauled together

Since then, it is necessary to set up different types of maintenance devices to enclose the inner side wall or the inner bottom of the aqueduct, and then carry out maintenance on the inner side wall and inner bottom of the aqueduct respectively. From this, the maintenance efficiency will be low. At the same time, The inner wall of the aqueduct and the inner connection cannot be effectively repaired, and the aqueduct after repair still has potential safety hazards
