Research on key technologies of plastic concrete anti-seepage wall in severe geology of soil loss
Concrete anti-seepage wall is a relatively common underground diaphragm wall often used in municipal engineering works.It has the advantages of good anti-seepage performance,and they are highly durable in structure and adpable to various complex geology.However,both at home and abroad,the anti-seepage wall is rarely used in the base of rubble mound embankment to prevent the circulation of the heated water and cooling water.In reference with the project in construction,taking into account the characteristics of the anti-seepage wall constructed for Xudapu Nuclear Power Plant in Liaoning,the present paper elaborates accentually on the key techniques in the construction of the anti-seepage wall in the geologic condition with severe soil loss,especially in the aspect of the work quality control and the performance of the plastic concrete,The emergence of the technique has helped solving the problems of soil claps in the drillng holes due to the soil loss and the unbalanced water pressure between two sides of the wall.The the measures taken for solving the problems has provided references for the with similar projects and has high value in practical application.
