| Abstract: | The blemish is a familiar and important reinforced concrete to drill a hole to infuse to note a quantity problem.This text passes the analysis to an example,introduce the method of replacement for head of stake that is "eliminate the concrete up down to arrive the position when its strength attains the standard,and then expand the path and connect the stake arrives to design the elevation use the concrete that its strength higher one grade than body." That method can handle the problem of a blemish quickly and availably. |
