Huanghe Longkou Hydro Project Consolidation Grouting Of The Optimization And Application

This paper takes longkou water conservancy project engineering construction, water conservancy hub A standard longkou consolidation grouting production conditions, according to the longkou water conservancy hub consolidation, curtain grouting technology and construction drawings, according to the provisions of the implementation of organizational design guidelines, detailed understanding of engineering construction before the topography and geology and hydrogeology conditions. According to the actual situation, the different hole spacing, different hole deep and different grouting way, have no cover with lid heavy weight, mainly for consolidation grouting test below the main content of research(1)no cover the area, heavy consolidation grouting of leakage, take pulp handled(2) how to control the dynamic, how to carry more grouting pressure(3)using water pressure test or a form of rock wave effects. Check whether(4)different hole hole and test the row spacing(5)there with no cover cover heavy weight of comparative advantage of consolidation grouting.(6)The authorized slurry grouting closed end to change, the standard of grouting effect(7)In the meantime the subject test time due to the cross with concrete construction time is too long, select the reasonable grouting.(8) Whether can LuoYan argumentation are not heavy consolidation grouting (9) construction parameters reasonably select the optimal B standard consolidation grouting and the hole, row spacing, construction technology, and choose the best Research, technical route, etc(10)Connectivity with different consolidation grouting engineering longkou hub and A standard of grouting test using the rationality and optimization to prove test resultsThrough different grouting test, the optimization of various parameters were compared, and the test method is analyzed, and the application of the production practice of drilling holes layout, filling and parameters of the drill procedure is optimized, filling the grouting parameter selection according to construction. A standard for longkou water conservancy hub follow-up grouting and longkou B standard consolidation grouting provide reasonable grouting parameter, the construction of experiment in the result of using and construction practice, not only accelerate the wash-or e of concrete construction speed based, shorten the construction period, solve the dam concrete pouring and consolidation grouting of interference, and to create better economic benefits, greatly reducing the A and B standard consolidation grouting of longkou city construction investment.
