3rd step, continue to transfer test rope, transfer test rope if cannot continue, then illustrate that sediment thickness is greater than the chaining pin degree of depth, do not meet working design requirement, need again clear hole, reduce sediment thickness, if continue below test rope, then test rope is transferred to till test steel plate arrives sediment end face, carry out second time test, read lining rope reading H
2.
4th step, calculates sediment thickness
According to first time test data and second time test data, can obtain first time test chaining pin tail end when touching bearing stratum bedrock surface at the bottom of priming concrete pile hole hole, the distance in test steel plate and sediment face is:
Δh＝H
2-H
1；
Can determine thus, enter the sediment thickness of rock filling pile:
h＝h
z-Δh＝h
z+H
