  对于钢板桩的施工,堵塞钢板桩的一般做法是在施加钢板桩的过程中,用棉绒和黄油等填料填充接缝。 一开始,我们也采用了这种方法。 效果不是很令人满意。 在全部插入钢板桩并安装抽水围堰后,采用沿钢板桩接缝滑动水并干燥细砂的方法。 钢板桩主要包括国内和进口类别。
  For the construction of steel sheet piles, the common method of blocking steel sheet piles is to fill the joints with cotton wool and butter fillers in the process of applying steel sheet piles. In the beginning, we also adopted this method. The effect is not very satisfactory. After all steel sheet piles are inserted and pumping cofferdam is installed, the method of sliding water along the joint of steel sheet piles and drying fine sand is adopted. Steel sheet piles mainly include domestic and imported categories.
  家用钢板桩主要包括鞍座IV型和IV型拉森(U型)。 家用钢板桩的使用条件要求更高,更多地用于深度较小的基坑支护。 进口钢板桩在质量和成本上都具有很大的优势,因此在实际的水利工程中被更多地使用。 日本和美国是生产更多钢板桩的。 安装笼子时,应对其进行测量和定位。 通常使用由导向框架层制成的笼子首先定位桩,然后将导向框架安装在定位桩上。 导向架可以在岸上形成并漂浮在适当的位置。 插入电缆锚之后,将导向框架逐渐悬挂在完成的板桩上。 当使用带有手摇桩的旋转木马或旋转桩架时,可以将导向架悬挂在外侧。 在那堆脚上。
  Household steel sheet piles mainly include saddle type IV and type IV Larsen (U). The domestic steel sheet pile is more suitable for the foundation pit with less depth. Imported steel sheet piles have great advantages in quality and cost, so they are more used in actual water conservancy projects. Japan and the United States are countries that produce more steel sheet piles. When installing cages, they should be measured and positioned. Generally, the cage made of the guiding frame layer is used to locate the pile first, and then the guiding frame is installed on the positioning pile. The guide frame can be formed on the shore and floated in an appropriate position. After inserting cable anchor, the guide frame is gradually suspended on the completed sheet pile. When using a merry-go-round horse with a hand-driven pile or a rotating pile rack, the guide rack can be suspended outside. On that pile of feet.

  对于钢板桩的施工,通常使用浮轮式或旋转桩架时,首先使用旋转桩架先将桩定位后再安装导向架时,通常将旋转桩架先定位 堆然后引导框架。 钢板桩的保持和渗漏以及基础压实灌浆和密封被用于使基坑快速挖掘到预定高度。 在对基坑表面进行处理之后,可以浇注底板的混凝土垫层,从而进行下一步施工。 有利的条件不仅改善了工程进度,而且对雨季影响较小,确保了整个工程的顺利进行。
  For the construction of steel sheet piles, when floating wheel or rotating pile bracket is usually used, the rotating pile bracket is first used to locate the pile before installing the guide bracket, and the rotating pile bracket is usually used to locate the pile first and then guide the frame. Preservation and leakage of steel sheet piles and compaction grouting and sealing of foundations are used to rapidly excavate foundation pits to predetermined heights. After the foundation pit surface is treated, the concrete cushion of the bottom plate can be poured to carry out the next construction. The favorable conditions not only improve the progress of the project, but also have little influence on the rainy season, which ensures the smooth progress of the whole project.
  基坑监测的频率随土方开挖进度和基坑的变化而调整。 基坑开挖过程中的开挖频率不小于2次/ d,开挖完成后开挖频率不小于1次/ d。 如果观察到的钢板桩顶部的位移突然增加,则应适当增加观察次数。
  The frequency of foundation pit monitoring is adjusted with the progress of earthwork excavation and the change of foundation pit. Excavation frequency is not less than 2 times a day in the process of foundation pit excavation, and not less than 1 time a day after completion of excavation. If the observed displacement at the top of steel sheet pile suddenly increases, the observation times should be increased appropriately.
  对于钢板桩施工,当观察到的位移趋于稳定时,可以延长观察间隔。 插入钢板桩时,应严格控制桩的垂直度。 特别是,应同时从两个垂直方向控制堆桩,以确保垂直方向不偏斜。 通常在垂直引导设备的引导下,首先将所有钢板桩或钢板桩插入稳定的深度,然后打入至设计深度。 插入顺序根据施工组织设计进行。 通常,将两端从上游插入到下游,并且在插入之前将混合物涂上黄油,木屑等。 组装桩时,用油灰和棉布缝被以防止漏水。
  For steel sheet pile construction, the observation interval can be extended when the observed displacement tends to be stable. When inserting steel sheet piles, the verticality of piles should be strictly controlled. In particular, the first pile should be controlled from two vertical directions at the same time to ensure that the vertical direction is not deflected. Usually, under the guidance of vertical guiding equipment, all steel sheet piles or steel sheet piles are inserted into a stable depth, and then into the design depth. The insertion sequence is designed according to the construction organization. Usually, both ends are inserted from upstream to downstream, and the mixture is coated with butter, sawdust, etc. before insertion. When assembling piles, they are sewn with putty and cotton cloth to prevent leakage.
