Method of preventing and handling water leakage of reinforced concrete culvert

Abstract

The invention relates to a method of preventing and handling water leakage of a reinforced concrete culvert. A groove is excavated along a leakage seam in a culvert inner wall, one-stair steps which are shrunken inwards are arranged on the inner walls of the both sides in the groove, multiple pairs of expansion bolt holes are drilled in the steps on the both sides in the groove, a half-section tube with the appropriate diameter is selected according to the inner width of the groove, the half-section tube sleeves in an inverse filtering geotextile sleeve, the half-section tube is installed in the groove, expansion bolts are embedded into the expansion bolt holes separately, and a steel wire is connected between each pair of expansion bolts to firmly fix the half-section tube; a guiding tubewhich extends to the outside of the groove is connected to the lower end of the half-section tube; and finally, an appropriate sealing material is selected according to the type of the leakage seam to block the internal space of the groove and the groove mouth.

Description

technical field [0001] The invention relates to the technical field of prevention and treatment of water leakage of reinforced concrete structures, in particular to a method for preventing and treating water leakage of reinforced concrete culverts. Background technique [0002] A culvert is a passage drainage channel built under the road surface in order to allow water canals, pedestrians and vehicles to pass smoothly without hindering traffic during the construction of highways and railways. As one of the important components of highway engineering, culverts account for a relatively large proportion of highway engineering. They are mainly used to discharge floods across natural valleys and depressions, or across large and small roads as overpasses for people, livestock and vehicles, or for farmland irrigation. as a canal. At present, the dual-purpose drainage culverts in the field of highway and railway engineering are mainly reinforced concrete slab culvert structures. ...

Problems solved by technology

Conventional grouting and caulking are effective in the short term, and the disease will reappear soon. At the same time, it is difficult to solve the problem fundamentally because of the difficulty of reprocessing after the initial treatment
