Problems solved by technology

Since the flexible packing sold in the domestic and foreign markets has viscosity and certain elastoplastic properties, and it is constructed on the steep slope of the dam, manual compaction is not strong enough and compaction is extremely difficult
Therefore, manual compaction of flexible packing is ine

Example Embodiment

[0019] Such as figure 1 As shown in the schematic diagram of the construction process, the protective cover 3 is located just above the joint surface 2 of the concrete face rockfill dam panel 1, and the protective cover 3 is connected with the metal bead 5 and the bolts 7 passing through the reserved hole 6 of the metal bead. Fixed on the concrete panels 1 on both sides of the joint surface, so that the protective cover 3 and the concrete panel form a cavity 8 along the joint surface. Before the protective cover 3 is in place, the glue stick 4 should usually be fixed first. When the protective cover 3 is fixed, the fixed position of the metal bead 5 and the bolt 7 and the width of the convex part of the reserved protective cover 3 are determined according to the outer contour shape of the section of the flexible filler 10 to be embedded in the fourth process. Manually and / or mechanically press the flexible filler 10 for caulking into the cavity 8 through the glue injection por...

Abstract

The invention provides a method for jointing and caulking construction of a concrete face rockfill dam face. The method is characterized in that a protecting cover plate is arranged on the jointing surface of the concrete face rockfill dam face; the protecting cover plate is fixed to the concrete faces on the two sides of the concrete face rockfill dam face by metal pressing strips and bolts penetrating through the metal pressing strips to form a cavity between the protecting cover plate and the concrete face along the jointing surface; and when the protecting cover plate is fixed, the fixing positions of the metal pressing strips and the bolts and the width of the raised part of the reserved protecting cover plate are determined based on the shape of the outer profile of the cross section of the flexible packing to be embedded and filled. The flexible packing for caulking is pressed into the cavity by labor and/or machines, and the protecting cover plate is expanded into the required raised cambered surface under the action of the filling pressure of the flexible packing in the protecting cover plate. According to the method, the problems of low efficiency and low quality in embedding and filling joint materials in jointing and caulking construction of the concrete face rockfill dam face can be effectively solved.

Description

technical field [0001] The invention relates to a construction method, in particular to a method for caulking construction of face joints of concrete face rockfill dams. Background technique [0002] Concrete face rockfill dam is a dam form widely used in the construction of hydropower stations at home and abroad, and has become the main comparison or preferred dam type in my country. In the next 10 years, with technological progress, my country will promote the construction of more face rockfill dams. [0003] The concrete face rockfill dam uses the rockfill body as the main force-bearing structure to bear the reservoir water pressure, and the reinforced concrete face plate poured from bottom to top on the facing surface of the rockfill body is the anti-seepage structure. Due to factors such as the settlement and deformation of the dam body, the concrete panels need to be poured in blocks, so that dozens of joints are formed between the panel blocks, the plinth and the pan...
