每一只抽沙船都缺少不了定位樁，所謂的定位樁就是為一根卷板構(gòu)成筒狀的構(gòu)件，下端呈錐形，外形相似于一支鉛筆，故又稱鉛筆樁。底部一般灌注石塊或鐵塊，以降低重心。
抽沙船均有兩根固定樁。施工時，主樁位于開挖中心線上并保持插入狀態(tài)，副樁保持懸空狀態(tài)。當(dāng)需要挖泥船前移、改變絞刀的縱向切土?xí)r，主副樁交替下落。嚴(yán)禁兩根固定樁同時下落進(jìn)行施工生產(chǎn)及抗風(fēng)。
為什們要安裝定位樁呢？是因為定位樁具有以下作用：
1、其主樁安裝在一個由液壓油缸推動、可相對于船體作短距離前后移動的臺車上。其作用是大大減少了換樁的時間，提高了生產(chǎn)效率。
2、克服軌道變形
3、提高液壓控制系統(tǒng)的性能
4、開發(fā)多功能組合系統(tǒng)
Each pumping sand are the lack of a positioning pile, the so-called positioning pile is a root bending cylindrical component, the bottom is tapered and similar to the profile to a pencil, so it is also called pencil pile. At the bottom of the general perfusion of stone or iron, to lower the center of gravity.

Have two fixed pumping sand pile. During construction, the main pile is located on the excavation center line and keeps the insert state. When the longitudinal cutting soil need to dredge forward and change reamer, main and auxiliary pile falling alternately. Construction production and wind resistance of two fixed piles are strictly prohibited at the same time.

Why do we have to install the positioning of the pile it? Because the positioning of the pile has the following role:
1、其主樁安裝在一個由液壓油缸推動、可相對于船體作短距離前后移動的臺車上。其作用是大大減少了換樁的時間，提高了生產(chǎn)效率。
1, the main pile is installed in a hydraulic cylinder drive, can be relative to the hull for a short distance before and after the movement of the trolley. The effect is greatly reduced the time for changing the pile, and the production efficiency is improved.
2、克服軌道變形
2, to overcome the track deformation
3、提高液壓控制系統(tǒng)的性能
3, improve the performance of hydraulic control system
4、開發(fā)多功能組合系統(tǒng)
4, the development of multi function combination system |
