发布时间:2016-5-16 9:20:06 浏览次数:840

锤击法


hammering method


打桩锤的种类有柴油机打桩锤、蒸汽锤、落锤、液压打桩锤、气动打桩锤等。


The hammer type diesel pile hammer, steam hammer, hammer, hydraulic hammer, pneumatic hammer etc..


该方法设备成本低、击打力大、机动性好、打击速度快,但打桩锤必须适宜,以防桩头击打压坏。锤击法会产生噪音和振动,在居住区、学校、医院等环境周边或其它特定区域使用受限。


The method has low cost, large impact force, good maneuverability and fast attack speed, but the pile driving hammer is suitable for the pile head to suppress the bad impact. Hammer method will produce noise and vibration, in residential areas, schools, hospitals and other environmental surrounding or other specific areas of limited use.


振动法


 vibration method


通过振动捶产生竖向振动力,带动钢板桩上下振动从而打入土层。因为没有冲击力,钢板桩桩头不会损伤, 施工效率较高,打入、拔出均较便利,适用于多数工程。振动法非为电动式和液压式两种。电动式振动法瞬间电流很大,需配备大型电力设备供电;而液压式则需要配备专用液压装置。通常振动法噪音也不小,因震动二产生的地址颤动幅度也较大。


Vertical vibration through the vibration hammer, driven by steel sheet pile under vibration so as to enter the soil. Because there is no impact force, steel sheet pile head can not be damaged, and the construction efficiency is higher, scoring, pull out were more convenient, applicable to most engineering. Vibration method for electric and hydraulic two. The electric vibration method is very large, it needs to be equipped with large power equipment power supply, and the hydraulic type is required to be equipped with special hydraulic device. Vibration method is usually not a small noise, vibration two caused by the address jitter is also larger.
