Embodiment Construction

[0022] Such as figure 1 , figure 2 As shown, the present embodiment is a repair structure and construction method for bulging and damaged concrete panels, including old concrete panels 101, old toe boards 102 around the old concrete panels, copper waterstop I 103 installed in the old concrete panels, and old concrete panels. The vertical seam between the concrete face plate 101 and the old toe board 102, the surface waterproofing of the peripheral seam (including the vertical seam, the plastic waterproof filler in the V-shaped groove on the top of the peripheral seam, the seepage protection cover, the fixed flat steel / angle steel, the fixed bolts, etc.), the upper part of the old concrete panel 101 has a number of cracks, and the uppermost crack 104 is the main control factor for determining the repair area, that is, the repair range is the outward or upward expansion distance d1 of the crack 104; Repair the surface waterproofing of the vertical joints and peripheral joints ...

Abstract

The invention relates to a repair structure for concrete panel buckling damage and a construction method. The repair structure aims at achieving the purposes that damage to an old concrete panel seepage prevention system is reduced, the repaired structure can be effectively fused with the original seepage prevention system, and the safety and reliability of engineering operation are enhanced. According to the technical scheme, the repair structure comprises an old concrete panel and an old toe board arranged on the periphery of the old concrete panel and copper waterstops I mounted in the old concrete panel, the old concrete panel is provided with multiple cracks, the repair range is determined according to the crack on the top, and after surface waterstops in the vertical seam and the peripheral seam within the repair range are removed, V-shaped grooves in the tops of the vertical seam and the peripheral seam are backfilled with M20 cement mortar flushed with the upper surface of the old concrete panel; a new toe board is poured on the old toe board, and the surface of the old concrete panel is sequentially laid with geotechnical cloth and emulsified asphalt; and cooper waterstops II with F-shaped or W-shaped or special-shaped connectors are mounted on the upper portion of the emulsified asphalt, and the new concrete panel is poured.

Description

technical field [0001] The invention relates to a repair structure and construction method for concrete face bulging damage, which is mainly suitable for repairing works of similar damage forms such as concrete face rockfill dam face bulging damage. Background technique [0002] Concrete face rockfill dams are widely used because of their good economy, fast construction and engineering reliability. For concrete panels, there are many failure forms, and bulging failure is one of the failure forms. The reasons for the bulging failure of the slab are as follows: the reverse water in the dam foundation was not removed in time, which caused the bulging and cracking of the concrete slab; the dam body was filled with materials with large lateral deformation, and the dam material swelled after encountering water, resulting in the bulging failure of the slab; construction In the early stage, the dam body was not compacted by rolling, and in the later stage, the excessive settlement ...
