Microbial improved riverway revetment device and construction method

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of river bank revetment engineering, in particular to a microbial improvement river bank revetment device and a construction method. Background technique [0002] Traditional river revetment protection often focuses on the stability of the river bank and the effect of flood control, and most of them use cement and other hardened revetment methods. The extensive use of cement and river sand in this method not only has a great impact on the environment, but the hardened revetment completely hinders the interaction of the ecosystem between the river bank and the river bed, and the river bank ecosystem is greatly damaged. In addition, the design of the traditional hard bank slope protection may also cause the transfer of the problem of erosion and erosion damage to the downstream river bank. From the perspective of modern sustainable development, the development and management of rivers must consider the sustai...
