Study On Reinforce Of Er Wang Zhuang Dam By High-pressure Sprinkle Mixed Bentonite Into Auti-seepage Wall

Er Wang Zhuang Dam is Tianjin City to lead the Luan He River into the Tianjin important engineering. Because the dam usually is placed in the water level quickly rises the quickly falls and super supplement water etc. and the nature factor affects, causing the dam round the dike to seep into the subject serious, affect the normal movement of dam. Er Wang Zhuang Dam reinforing engineering is an important engineering strengthenning the reservoir circulate the safety.Er Wang Zhuang Dam is plain dam, the dam rounds the dike long, geology and seep into the disaster complicacy,it is important to how to choice to reinforce the scheme.Textual main operations is as follows:1. According to two the geology investigates data, recognize the dam round dike and dike soil forms, for reinforcing offering according to.And the geology investigates data recognizes while dam is rounding the dike and dike soil constitution, also recognizing to round the dike seep into serious and serious dike segment.2.Check the cultural heritage data, understand the dike that plain dam reinforce tool, and according to Er Wang Zhuang Dam geology, seep into the condition and defend the seeping into reinforce the engineering the volume , the construction is difficult easy the extent, engineering builds price etc. comparising to every kind of scheme, passesing the comparison recognize to adopt high-pressure sprinkle .3. According to indoors experiment study the flexibility spoilage and glue sex and piastics etc. According to the Er Wang Zhuang Dam actual condition in dike, wanting the certain piastics again, then propose to mix bentonite ,passing the dam round the dike high- spessure sprinkle on trial segment, recognize the cement and glue and bentonite and also approval the test expresses bentonite impacting piastics.4. reinforcing scheme and the flexibility formes is recognized behind to start engineer, First, passing trially recognize high-pressure sprinkle technique parameter, the next in order, investigate tally up high-pressure sprinkle, howing to steer the quality controling.5. after Engineering finishing, the approval measures to press the tube and test defend the of wall seeping into result and wall mechanics function, then assessing the engineering quality . analysing community and economic benefits of mixing the bentonite in wall.
