Background
With the development of the Chinese railways, higher requirements are put forward on foundation engineering, particularly on the foundation of the bored pile. The accurate measurement of the sediment at the bottom of the drilled pile hole is an effective way for ensuring and improving the quality of the drilled pile. The existing detection methods for the sediment condition of the hole bottom of the drilled pile comprise a hammer detection method, a sampling box detection method and a sediment instrument detection method. The three have the following defects in use: the hammer measurement detection method needs to be frequently checked before and during use, and when abrasion, unclear figures or displacement of standard numbers occur, the measuring rope needs to be replaced in time. The method for detecting the thickness of the sediment at the bottom of the hole is visual and is a commonly used method at present, but the method has the defects that manual judgment is excessively depended on in specific operation, and the result of the manual judgment is different from person to person, so that the accuracy of the result of the method is not high.
The sampling box detection method is characterized in that a sampling box (an opening box) is hung to the bottom of a hole after hole cleaning is finished and is taken out before concrete is poured, and the thickness of the residue soil in the box is the thickness of the sediment at the bottom of the hole. The method has the defects that the actual operation difficulty is higher, if the sediments taken out before filling exceed the standard, the hole cleaning is needed continuously, the construction period is delayed, and the quality problem is easy to cause.
The sediment instrument detection method needs to be calibrated before measurement, and is applied to large and key projects at present. But the defects are that the cost of the instrument is high, the calibration is needed in the using process, the construction cost is increased, and the instrument is difficult to popularize in small and medium-sized projects, so that a detection tool for measuring the sediment of the bored pile with low cost and high precision is lacked in the market.
