Embodiment Construction

[0008] Such as figure 1 As shown, the arrangement and hole making of the first grouting holes: the grouting holes 13 are arranged in a quincunx shape, and the first, second, and third rows of holes are all located on the cracks 14, and the row spacing and hole spacing are both 4 to 5 meters. The grouting hole is to pass through the lining base plate with a 1-inch iron pipe, and then go deep into the foundation 20 cm, and expose 10 cm to connect with the grouting pipe. Before grouting, the cracks in the lining layer at the bottom of the canal should be chiseled and cleaned, and the small cracks should be repaired with No. 80 mortar and the large cracks should be repaired with No. 150 concrete.

[0009] The second step is the preparation of the yellow mud slurry: to prepare the slurry, yellow mud with many clay particles and small coarse grains should be selected. The gradation is: 42% of the particle size is less than 0.005 mm, 34% of the particle size is 0.005 ~ 0.05 mm, 0.05 ...

Abstract

The invention relates to a method for treating depression watertight in hydraulic engineering by employing yellow mud grout, which comprises disposing grouting borehole, pore-creating, formulating yellow mud grout, arranging grouting equipment and grouting. The yellow mud grouting treatment can produce a layer of hard yellow mud between the starching and laying rock block bottom board and the ground foundation.

Description

Technical field: [0001] The invention relates to a treatment method for subsidence and water leakage of hydraulic engineering. Background technique: [0002] Water conservancy projects, especially the soil under the embankment of filled ditches are mainly silt soil and sandy loam soil, which has high compressibility and strong water permeability. Subsidence is easy to cause the lining layer at the bottom of the canal to be pulled apart, resulting in water leakage from the cracks. There are two comparative plans: one is to add a 40 cm thick reinforced concrete floor on the anti-seepage slab at the bottom of the canal, which requires cement and steel and requires a large investment. The second is to use glass cloth and epoxy resin to patch. However, it is difficult to subsidize large areas, and the pasted glass cloth is easily aged when exposed to the atmosphere for a long time, and must be processed after aging. Invention content: [0003] The object of the present invent...
