Compressible water stop structure for concrete panel joint surface layer in severe cold area and construction method

Abstract

The invention discloses a compressible water stop structure for a concrete panel joint surface layer in a severe cold area and a construction method, and belongs to the technical field of concrete panel joint seepage-proofing sealing. The compressible water stop structure comprises concrete panels, caulking bodies, compressible strips and flexible seepage-proofing coatings, wherein a joint is reserved between every two adjacent concrete panels, and filling grooves are formed in the upper portions of the joints; the caulking bodies are embedded in the filling grooves; the compressible strips are arranged on the surfaces of the caulking bodies in the extending direction of the joints; and the flexible seepage-proofing coatings cover the caulking bodies and the compressible strips and are bonded to the panel faces of the two concrete panels correspondingly. The construction method is used for constructing the compressible water stop structure for the concrete panel joint surface layer in the severe cold area. The compressible water stop structure is easy to construct, good in seepage-proofing performance, high in durability, large in deformation resistance and suitable for panel dam new construction and constructed project repairing under the condition that the water surface of a reservoir in the severe cold area is frozen.

Description

technical field [0001] The invention relates to the technical field of anti-seepage and sealing of concrete panel joints, in particular to a compressible water-stop structure and a construction method for the joint surface of concrete panels in severe cold regions. Background technique [0002] The description of the background technology of the present invention belongs to the relevant technology related to the present invention, and is only used to illustrate and facilitate the understanding of the content of the present invention. prior art on the filing date. [0003] Concrete face rockfill 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 anti-seepage system of concrete slabs, the watertightness of the joints of concrete slab dams is still a weak link. At present, flexible waterproof coiled materials are gener...
