Tianjin Jiuxuanzha Consolidation Project Of Soil And Water Loss Prevention And Control Measures

Jiuxuanzha of Tianjin, Tianjin gate bears solve water diversion Yellow River toTianjin ’s task, according to North Water Transfer Project planning requirements, theSouth Born in the canal will be two, three50m3/s,100m3/s of traffic diversion, itrelates to the security of water supply in Tianjin region, nine gates declared as one ofthe important part, over the water must meet their requirements; due to its longerlife, lower design standards, smaller, aging of the project run so far, the gate beganto leak. In2006, jiuxuanzha security assessment identified four categories of gates,the proposed demolition and reconstruction. According to China’s relevant laws andregulations, soil and water conservation, for the effective implementation of the "who develops protection, who who caused soil erosion control," clearly theconstruction of erosion control shall bear responsibility, with the main projectimplementation," designed, constructed, and put into use,"the three principles at thesame time, and finally to the construction of regional soil erosion can be timely andeffective control, to achieve win-win development and construction and ecologicalconstruction purposes.This article is mainly soil erosion demolition and reconstruction of the gate afterthe analysis and study, according to the impact on soil erosion caused by theconstruction of predictive analysis and prevention of soil erosion. Through the projectduring the construction process will inevitably surface disturbance, Dregs, destructionof the ecological environment artificially induced erosion. Vegetation and soil erosionbased on the amount of the original topography of the soil may damage reasonablypredict the construction process, to determine the effects of soil erosion factors, basedon the analysis and evaluation to determine the time and method of forecasting,rational arrangement of the various control measures to reduce soil erosion damage tothe soil, keeping the sustainable use of land resources; reduce the sediment siltation ofcanals and rivers, to avoid adverse impacts on local flood control waterlogging. Inaddition, greening and beautification projects in the region to create a goodenvironment. In the development of the local economy, improve economic efficiency,protecting soil and water resources, to achieve the construction of social andenvironmental benefit.
