Plugging method of improved embankment-penetrating culvert
The invention discloses a plugging method of an improved embankment-penetrating culvert. The plugging method comprises the following steps: (1) pouring end-sealed walls at openings in two ends of a culvert to be plugged, pre-burying pressure grouting pipes in the end-sealed walls, and pre-burying a consolidation drainage pipe and a hole for pumping a hydraulic reclamation sand pipeline in one of the end-sealed walls; (2) inserting a pumping sand blowing and filling pipeline into the hole of the pumping sand blowing and filling pipeline in a penetrating mode; (3) standing, after the end-sealed wall body reaches the designed strength, using a power pump for blowing and filling sand into the culvert step by step through the sand blowing and filling pumping pipeline till filling is dense, and draining water through the consolidation drainage pipe; and (4) after hydraulic reclamation sand in the culvert is solidified and a filling gap appears in the top of the culvert, pouring cement paste or a high polymer material into the culvert through the pre-buried pressure grouting pipe to fill the gap tightly. According to the plugging method of the improved embankment-penetrating culvert, the culvert can be densely plugged, potential safety hazards are thoroughly eliminated, and flood prevention and flood control safety of a flood control embankment is guaranteed.
本发明公开一种改进型穿堤涵洞的封堵方法，包括以下步骤：①在拟封堵涵洞的两端洞口浇筑封端墙体，浇筑在所述封端墙体内同时预埋压力注浆管，并在其中一所述封端墙体内预埋固结排水管以及泵送吹填砂管道的孔洞；②从所述泵送吹填砂管道的孔洞中穿插泵送吹填砂管道；③静置，待所述封端墙体达到设计强度后，利用动力泵通过所述泵送吹填砂管道向涵洞内逐步吹填砂，直至灌填密实，并通过所述固结排水管排水；④所述涵洞内的吹填砂固结后，所述涵洞顶部出现填充缝隙后，通过预埋所述压力注浆管向所述涵洞内灌注水泥浆或高聚物材料将所述缝隙填充密实。本申请的改进型穿堤涵洞的封堵方法可密实封堵涵洞，彻底消除安全隐患，确保防洪堤的防汛、防洪安全。
