INTRODUCTION The drum type diesel pile hammer has the characteristics of simple structure and large striking capacity. It has been rapidly developed in China in the past ten years and now has a series of products. Such piling hammers can be used to hit wooden piles, steel piles and concrete piles, and are suitable for foundation construction of docks, slipways and various industrial and civil buildings. With the development of tubular diesel pile hammers, work has also been conducted to test their performance. Second, the purpose of the test can be divided into research tests and product performance appraisal tests. The purpose of the research experiment is to verify the correctness of the theoretical calculations at the time of design and to verify the rationality of some of the coefficient choices; the purpose of the accreditation test is to test whether the performance meets the design requirements and whether the performance is advanced. Third, the test content and the significance of the test Diesel drum hammer performance test includes the following:
