Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy project construction, in particular to a V-shaped groove cleaning device for water-stopping joints of an asphalt concrete core wall dam. Background Art

[0002] Asphalt concrete core wall dam has the advantages of low investment, short construction period, good safety, convenient construction, strong adaptability, etc., and has been widely promoted and applied at home and abroad. However, in the asphalt concrete panel anti-seepage system, the water stop of the asphalt concrete panel dam joints is still a weak link. At present, flexible waterproof membranes are generally used as protective cover plates to stop the water at the joints of concrete panel dams. Commonly used protective cover plate materials include EPDM rubber (EPDM) plates, rubber plates and composite rubber plates, etc., and are fixed to both sides of the concrete panel joints by expansion bolts. As one of the core anti-seepage structures, the surface water stop is used between the concrete panels to further form a complete anti-seepage system. During the construction process, the V-grooves reserved in the panels need to be cleaned, primed, leveled with plastic fillers, caulking, PVC rods placed, plastic fillers stacked, anti-seepage covers pasted to cover the plastic fillers, stainless steel flat steel pressed, stainless steel expansion bolts installed, and other processes. The concrete panels are located on the upstream slope of the dam body. The specific style of the V-grooves between the panels is that the 200mm range on both sides of the panel joints is 10mm lower than the panel surface, and the V-groove depth is about 60mm. The cleaning process mainly involves the slag filled in the V-grooves and the bonded stone slag. The cleaning process requires operators to clean along the slope, which is difficult, has high safety risks, and is inefficient. An efficient cleaning method is urgently needed.

[0003] The document with publication number CN215715074U discloses a V-groove cleaning device for the water-stop joints on the surface of a panel dam, including a body, a suspension mechanism and a cleaning mechanism; the cleaning mechanism is arranged on the external frame of the body through the suspension mechanism; the cleaning mechanism drives the first wedge-shaped wheel, the second wheel and the third wheel through the three sets of bevel gear sets on the cleaning motor and the transverse transmission rod, thereby realizing automatic cleaning of the V-groove part of the water-stop joints on the surface of the panel dam. After analysis, the disclosed technology is different from the structure of the utility model. Utility Model Content
