Distorted concrete grouting diffusing construction method

Abstract

The invention discloses a distorted concrete grouting diffusing construction method. An inserting-type grouting method which is adopted to conduct grouting and diffusing to distorted concrete includes the steps: determining or measuring a porosity factor e, an average particle diameter Dp, density Rho, and viscosity ug, and determining the radius r0 of a grouting pipe; primarily selecting grouting pressure delta p, and grouting time t; computing a formula 1 and a formula 2 for parameters and adjusting the grouting pressure delta p or / and the grouting time t to enable the grouting time t to be coincided with an actual interval L and then conducting grouting. After each parameter is determined according to mixture of concrete in the field, other parameters are adjusted according the radius of grouting diffusion, and construction is free of limitation of size flow patterns. According to actual project quality inspection, evenness of grouting diffusion is good in construction of distorted concrete, each parameter in construction is easy to obtain, construction efficiency is high, and demands to construction quality of grouting diffusion are satisfied. The method not only can guide design and optimization of a grouting device and a control system in grouting equipment, but also can conduct optimization to grouting technology.

Description

technical field [0001] The invention belongs to the technical field of concrete construction, in particular to the technical field of concrete grouting construction, in particular to a method for controlling and determining the diffusion and penetration radius of grouting in concrete grouting construction. Background technique [0002] Metamorphic concrete construction is carried out on the basis of roller compacted concrete mixture to improve anti-seepage performance and solve the problem that some parts of roller compacted concrete cannot be rolled by vibratory rollers. There are two main methods of grouting construction at present: one method is to directly sprinkle the accurately measured grout evenly on the paved roller compacted concrete mixture. Hydraulic structure engineering. Another method is to evenly and vertically make holes or dig grooves on the paved roller compacted concrete material, and then directly use tools to evenly sprinkle the accurately measured slu...

Problems solved by technology

Both methods cannot guarantee the uniformity of grout penetration, and the construction efficiency is low

One way to solve the problem of grouting uniformity is to use plug-in grouting equipment. Plug-in grouting needs to know the diffusion radius of grout penetration. However, there is no good way to determine the diffusion radius in metamorphic concrete construction at present.
