Please strictly refer to the drawings for installation, avoid blind construction. For the short plastic steel sheet pile, the hammer and pile cap can be manually inserted into the ground; For longer or less ideal ground conditions, it is recommended to directly use pile hammer (pneumatic hammer or light vibrator); For extremely harsh conditions or installation with a depth of 4 to 8m, it is recommended to use supporting steel sheet piles to penetrate hard areas as supports to speed up installation.
