A construction method for plugging reinforced concrete culverts of embankments

Abstract

The invention provides a blocking construction method for a dam reinforced concrete culvert pipe and belongs to the field of dam construction. The blocking construction method for the dam reinforced concrete culvert pipe comprises the steps of pouring concrete downstream of the culvert pipe and blocking the end part of the culvert pipe to form a concrete plug; then drilling a construction hole atthe top of the dam to make the construction hole drill through the top of the culvert pipe and extend to the interior fo the culvert pipe, then embedding a slurry pipe into the construction hole, andfilling the culvert pipe with the concrete through the slurry pipe to block the culvert pipe; and laying a waterproof membrane outside the concrete plug to cover the end part of the concrete plug. Bymeans of blocking the culvert pipe of a sand dam by the construction method, the culvert pipe can be blocked steadily, rapidly, safely and stably; meanwhile, the stability can be kept long after blocking and the disadvantages such as collapse and the like can be avoided during use.

Description

technical field [0001] The invention relates to the field of embankment construction, in particular to a construction method for plugging reinforced concrete culvert pipes of embankments. Background technique [0002] The reinforced concrete of the culvert is subjected to the erosion of pressure water, erosion, wear of suspended matter, and uneven settlement of the fill around the culvert, resulting in the wear and tear of the surface of the culvert, the precipitation of calcium in the cementitious material and the formation of nodules, the loosening of the concrete and the leakage of the steel bar. , the protective layer cracks and falls off, the steel bars are exposed, the culvert pipes are cracked, the pressure water seeps out, and the soil around the culvert pipes is emptied, resulting in leakage channels along the culvert pipes and the collapse of the embankment and dam, which seriously threaten the safety of the embankment and become a safety hazard. , Therefore, after...
