Rock-fill concrete construction method

Abstract

The invention provides a rock-fill concrete construction method. The rock-fill concrete construction method comprises the first step of stacking rocks inside a predetermined groove to form a rock-fill body, the second step of pouring self-compacting concrete on the upper surface of the rock-fill body until gaps between the rocks of the rock-fill body are filled with the self-compacting concrete, the third step of grinding the upper surface of the rock-fill body before the self-compacting concrete is initially solidified, and the fourth step of solidifying the self-compacting concrete to form rock-fill concrete. According to the rock-fill concrete construction method, the self-compacting concrete is poured on the upper surface of the rock-fill body directly, the gaps between the rocks of the rock-fill body are filled with the self-compacting concrete in a free-flow mode, and the upper surface of the rock-fill body is ground, so that the flowability of the self-compacting concrete in the rock-fill body is improved, air in the self-compacting concrete and air in the rock-fill body are conveniently exhausted, and the compactibility of the rock-fill concrete is improved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a rockfill concrete construction method. Background technique [0002] The traditional method is based on the method of block pouring, combined with temperature control measures, and has been widely used in the construction of large-volume concrete such as concrete dams, such as the early Hoover concrete gravity arch dam in the United States and the current Three Gorges concrete in China gravity dam. This construction method has gained a lot of experience in ensuring the quality of concrete construction and controlling concrete cracking, and is still the most common method of mass concrete construction at present. However, this method requires a large number of formworks and various temperature control measures such as embedded cooling water pipes, which has the disadvantages of many processes, high cost, and low construction speed. [0003] In recent years, a new large-...

AI Technical Summary

Problems solved by technology

If the water consumption of self-compacting concrete is too small, the flow performance of self-compacting concrete will be reduced, which will affect the compactness of rockfill concrete

If the self-compacting concrete uses too much water, bleeding may occur, which will affect the interlayer connection quality of rockfill concrete
