求翻译：拔桩时，可先用振动锤将板桩锁口振活以减少土的阻力，然后边振边拔。对较难拔出的板桩可先用振动锤将桩振打下100－300mm，再与振动锤交替振打、振拔。有时，为及时回填拔桩后的土孔，在把板桩拔至此基础底板略高时（如500mm）暂停引拔，用振动锤振动几分钟，尽量让土孔填实一部分。是什么意思？

Tension piles with vibratory hammer sheet pile locking vibration live in order to reduce the resistance of the soil, then edge vibration side pull. With vibratory hammer pile vibration more difficult to pull out the sheet pile can be the first to lay a 100-300mm, alternately rapping hammer and vibra

When you remove piles, you can use vibration pile hammer lock port board live in order to reduce vibration and vibration resistance, and then side edge. For the more difficult to pull out of the piling can use the vibration damping laid pile hammer WILL BE 100 - 300 mm, with a seismic hammer beat al

When pulling, start the sheet pile with vibration hammer lock vibration live in order to reduce the resistance of the soil, then vibrating edges drawn. More difficult to pull the sheet piles can be first with vibration hammer vibration pile laid 100-300mm, and alternating vibration vibrating hammer,

When pile pulling, may use to vibrate the hammer first to close up an opening the sheet pile inspires lives reduces the earth the resistance, then inspires while pulls out.To the sheet pile which difficult to draw out may use to vibrate the hammer first the pile to inspire overcomes 100-300mm, then
