筒式柴油锤的桩帽在结构上一般分为导向桩帽和无导向桩帽两种类型。(导向桩帽与无导向桩帽的区别,在于桩帽是否与桩架立柱的两根导杆有联系)无导向桩帽传递柴油锤的能量高于导向桩帽,特别是无导向桩帽的耐用度明显高于同性能的导向桩帽。如果能因地制宜合理使用无导向桩帽,将会带来明显的经济效益,反之,就可能影响柴油锤的长远的经济效益。由于桩插不垂直、地质构造复杂或某些其它因素影响使桩身在施工中途发生倾斜时,往往通过移动桩架或回转立柱的办法来校正桩的倾斜度。由于无导向桩帽只悬挂在柴油锤上而
The pile cap of the barrel type diesel hammer is generally divided into two types: a guide pile cap and a non-guide pile cap. (The difference between the guide pile cap and the non-guide pile cap is whether the pile cap is associated with the two guide rods of the pile post.) The energy of the non-guided pile cap transmitting the diesel hammer is higher than that of the guide pile cap, especially the guide cap The durability is obviously higher than that of the guide pile cap with the same performance. If it is reasonable to use non-guided pile caps according to local conditions, it will bring obvious economic benefits. Conversely, it may affect the long-term economic benefits of diesel hammers. When the pile is tilted in the middle of construction due to non-perpendicular piles, complicated geological structure, or some other factors, the inclination of the pile is often corrected by moving the pile rack or rotating column. Because no guide pile caps are hung on the diesel hammer
