Research on the Relationship between Effective Porosity and Ratio of Cement to Stone of Non-Sand Concrete Well Pipe

Abstract:

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.
