钢板桩分为IV型、V型和VI型,Ⅳ型拉森钢板桩是很常用的。由于我国自主生产的钢板桩质量没有国外的拉森钢板桩好,所以大型围堰施工中大多数是采用进口的钢板桩。钢板桩围堰结构需要支撑围堰的内部,根据围堰的大小和深度选择钢管、工字钢或H型钢。小围堰可以根据自己的经验进行施工,但遇到大型围堰时,围堰的整体结构需要进行设计。通常采用有限元分析软件对围堰进行设计,以保证围堰整体结构的稳定性。
Steel sheet pile is divided into IV type, V type and VI type. Because the quality of steel sheet pile produced by our country is not as good as that of Larsen steel sheet pile abroad, most of the steel sheet piles imported are used in the construction of large cofferdam. The steel sheet pile cofferdam structure needs to support the inner part of the cofferdam. According to the size and depth of the cofferdam, steel pipe, I-beam or H-beam are selected. Small cofferdams can be constructed according to their own experience, but when large cofferdams are encountered, the overall structure of cofferdams needs to be designed. The finite element analysis software is usually used to design the cofferdam to ensure the stability of the whole structure.
钢板桩的后期工作包括钢板桩的防渗漏检查和钢板桩的提取。防漏检查仍然比较简单,只要注意钢板桩的动力以及外部条件的变化对钢板桩的影响,例如止水钢板桩应注意水、浪的高度,及时做好钢板桩的影响预防工作。
The later work of steel sheet pile includes anti leakage inspection and extraction of steel sheet pile. The leak proof inspection is still relatively simple, as long as we pay attention to the influence of the dynamic force of the steel sheet pile and the change of external conditions on the steel sheet pile, for example, the height of water and waves should be paid attention to for the water stop steel sheet pile, and the prevention of the influence of the steel sheet pile should be done in time.

然而,钢板桩的提取应注意一些技巧,根据打桩的情况确定拔桩的起始点,拔桩的起始点与角度桩相距5根以上,拔桩顺序与打桩顺序相反,也可采用跳桩法。当桩被放置时,板桩的锁孔可以用振动锤振动,以降低土的粘着性,然后在振动时将桩拉出。对于难以拔出的板桩,用振动锤可将其振动至100×300 mm,振动锤可与振动锤交替进行15 min的振动和拉振,然后用振动锤交替地振动和拉振。及时拉桩后填土孔。
However, the extraction of steel sheet pile should pay attention to some skills. The starting point of pile pulling should be determined according to the situation of pile driving. The starting point of pile pulling should be more than 5 piles away from the angle pile. The sequence of pile pulling is opposite to that of pile driving. The pile jumping method can also be used. When the pile is placed, the lock hole of the sheet pile can be vibrated with a vibrating hammer to reduce the adhesion of the soil, and then the pile can be pulled out during the vibration. For the sheet pile which is difficult to pull out, it can be vibrated to 100 × 300 mm with a vibrating hammer. The vibrating hammer can alternately vibrate and pull with the vibrating hammer for 15 min, and then vibrate and pull alternately with the vibrating hammer. Fill the hole after pulling the pile in time.
在钢板桩后期做好工作也是非常重要的,特别是在拔桩过程中。如果处理不好,就会影响钢板桩的回用。
It is also very important to do a good job in the later stage of steel sheet pile, especially in the process of pile pulling. If the treatment is not good, it will affect the reuse of steel sheet pile.
