Working Safely while saving time & cost
The document discusses optimizing foundation projects by addressing four key factors: 1) Optimising piling speed for different drilling depths and soil strata. 2) Piling fast and cost effectively. 3) Choosing the most cost effective deep shoring system. 4) Building basements waterproof while minimizing dewatering. It provides information on different piling and foundation techniques and emphasizes the importance of choosing the right drilling and cutting tools to pile fast and cost effectively depending on the soil strata.

Friction curve in this application seems not to be a key factor of analysis compared to wear describe in the following chart. Sample S1 - Curves Average friction coefficient : 0.72. The average value of friction coefficient varies between 0.68 and 0.75 and is stable for all samples. > Sample wear and wear track profile of ceramic tile Shank chisels wear has been defined as the lost weight during the test. Shank chisels were weighted before and after testing. The percentage of weight loss has been calculated and is presented in the following chart.

Therefore any type of surface modification (painting, coating etc.) will influence the contact. The painting will be removed with acetone. Moreover, norm ASTM G133 that is defined to test these samples represent a Linearly Reciprocating Ball-on-Flat Sliding Wear based on the following drawing. In the current shape, the sample cannot be fixed correctly to test the tip. Usually, the specimen to be investigated is at the bottom part and the ball specimen is provided by CSM Instruments. In your case, the “ball specimen” can be the tip. The flat specimen needs to be defined (materials ideally in contact in the real application) because it isn’t specified in the norm. In order to use the tip as the ball specimen, 2 solutions can be imagined. Either you can provide us the tip without “surrounding” or we will have to cut the shank chisel to keep mainly the tip. In this second solution, we would need you support. Could you provide us the length of the tip or better the drawing with internal dimensions of the tip, so that we would be able to saw the sample on the correct place?

The static partner, (a pin or a ball), is mounted on a stiff lever, designed as a frictionless force transducer. As the disk is rotating, resulting frictional forces acting between the pin and the disk are measured by very small deflections of the lever using an LVDT sensor. Wear coefficients for both the pin and sample are calculated from the volume of material lost during a specific friction run. This simple method facilitates the determination and study of friction and wear behavior of almost every solid state material combination, with varying time, contact pressure, velocity, temperature, humidity, lubrication, etc. How do you pile fast & cost effec7vely?
