Microbial improved riverway revetment device and construction method
The invention discloses a microbial improved riverway revetment device and a construction method. The device comprises a power conveying system and a slurry diffusion system, wherein the power conveying system comprises a slurry storage pool, slurry, conveying hoses, peristaltic pumps and grouting valves, inlets of the peristaltic pumps are connected with the slurry storage pool, and an inlet of each grouting valve is connected with an outlet of the corresponding peristaltic pump; the slurry diffusion system comprises grouting pipes with the number equal to that of the grouting valves; and slurry discharging holes are formed in the side walls of the grouting pipes, the outer walls are wrapped with geotechnical cloth, the bottoms are sealed, and the tops are connected with the conveying hoses connected with outlets of the corresponding grouting valves. The construction method comprises the following steps that mineralized bacteria turbid liquid is cultured to prepare cementing liquid; the side walls of the grouting pipes are wrapped with the geotechnical cloth and are perpendicularly pressed into a bank slope of a riverway revetment; and the grouting valves are opened, the peristaltic pumps are started, the mineralized bacteria turbid liquid is pumped into the grouting pipes, and the cementing liquid is pumped until the bank slope of the riverway revetment meets the improvementrequirement. The device is simple, construction does not need to damage an original riverway revetment, the construction cost is low, and energy conservation and environmental protection are achieved.
本发明公开了一种微生物改良河道护岸装置及施工方法：装置包括动力输送系统和浆液扩散系统；动力输送系统包括储浆池、浆液、输送软管、蠕动泵和注浆阀门，蠕动泵进口与储浆池连接，每个注浆阀门进口连接蠕动泵出口；浆液扩散系统包括与注浆阀门等数量的注浆管；注浆管侧壁布置出浆孔，外壁包裹土工布，底部均为封口式，顶部均与其所对应注浆阀门出口连接的输送软管连接。施工方法：培养矿化细菌悬浊液，配置胶结液；注浆管侧壁包裹土工布，垂直压入河道护岸岸坡；打开注浆阀门，开启蠕动泵，向注浆管中泵送矿化细菌悬浊液后，泵送胶结液；直到河道护岸岸坡满足改良要求为止。本发明装置简单，施工无需破坏原有河道护岸，施工成本低，节能环保。
