DDC桩的桩锤构造很有创新。它不是平面形状，而是呈尖锥杆状或呈橄榄状，比平面锤优越得多。夯击时，对下层填料是深层动力夯、砸、压密，对上层新填料是动力夯、砸、劈裂和强制侧向挤压。通过桩锤的动力夯击，在锤侧面上，产生极大的动态被动土压力，锤推土迫使填料向周边强制挤出，桩间土也被强力挤密加固。这是DDC桩技术独具特色之二。

DDC桩处理的地基，自上而下都得到加固，呈均匀密实状态。而强夯加固的地基上强下弱，有软弱下卧层时，则达不到地基加固的目的，这是DDC桩技术特点之三。

总之，用DDC桩处理地基的密实性和均匀性都好，加固深度大夯击能量高。而桩锤比强夯锤重量小，对机具要求条件低，所产生的公害也小，比强夯法有很大的优越性。

一、系统构成灵活，扩展容易，以开关量控制为其特长；也能进行连续过程的pid回路控制；并能与上位机构成复杂的控制系统，如ddc和dcs等，实现生产过程的综合自动化。

　　二、使用方便，编程简单，采用简明的梯形图、逻辑图或语句表等编程语言，而无需计算机知识，因此系统开发周期短，现场调试容易。另外，可在线修改程序，改变控制方案而不拆动硬件。

　　三、能适应各种恶劣的运行环境，抗干扰能力强，可靠性强，远高于其他各种机型。
