Abstract

The invention belongs to the technical field of hydropower engineering, and relates to a construction method of grouted concrete. According to the construction method of the grouted concrete, construction preparation is carried out before construction, a constructed foundation surface is treated, and then construction is carried out; and the construction method is characterized by comprising the following construction steps of 1, measuring and positioning a grouted area; 2, adding grout at the bottom, specifically, a, ridging; b, predicting the grout adding amount; c, actually measuring the grout adding amount; d, measuring the specific gravity of the grout; e, optimizing the grout adding amount; and f, optimizing the specific gravity of the grout; 3, placing roller compacted concrete; 4,carrying out concrete spreading; 5, carrying out vibrating operation; and step 6, carrying out surface finishing.

Description

technical field [0001] The invention belongs to the technical field of hydropower engineering, and relates to a construction method of grouted concrete. Background technique [0002] Roller compacted concrete dam building technology has the characteristics of fast and economical. Since the 1980s until now, the roller compacted concrete dam building technology has been perfected day by day, but some construction techniques still need to be continuously improved to meet the requirements of the RCC dam building technology. Requirements for rapid construction and quality compliance. [0003] During the construction of roller compacted concrete dams at home and abroad, grouted concrete (abnormal concrete) needs to be constructed around the upstream and downstream formwork, the periphery of the dam body corridor, the left and right bank roads, the bank slopes on both sides, and the reserved holes. The construction technology of concrete (metamorphic concrete) is constantly improv...
