Research on the Relationship between Effective Porosity and Ratio of Cement to Stone of Non-sand Concrete Well Pipe
Non-sand concrete well pipe is widely used in dewatering construction of deep foundation pit,the running effect of water-filtration well pipe have a close relationship with casting-pipe porosity,material ratio and casting-pipe time.With a long term test,the indicators critical values of casting-pipe based on maximum porosity is proposed,which is under a condition of ensuring the adequate strength of non-sand pipe and different proportion of limestone cement and stones.The critical values have a great significance to improving non-sand pipe effective porosity,reducing permeation resistance and increasing infiltration capacity,and also can provide a reference for the design and constriction of similar projects.
