拉森钢板桩在打入设定的深度后,如果坑要挖的比较深,这时候就要考虑开始做内支撑,来确保拉森钢板桩不会受外力倾斜。那么下面我们就来介绍一下拉森钢板桩支护内支撑怎么安装? 拉森钢板桩施工一般要安装坑内支撑做法是一边抽水,一边安装内支撑。抽水时应每抽1米稍微停一段时间,以使内支撑稳步受力,并及时堵漏。
After the Larsen steel sheet pile is driven into the set depth, if the pit is to be dug deeper, the internal support should be considered at this time to ensure that the Larsen steel sheet pile will not be inclined by external force. Now let's introduce how to install the internal support of Larsen steel sheet pile support? The construction of Larsen steel sheet pile generally needs to install the support in the pit. The method is to pump water while installing the support. When pumping water, it should stop for a period of time every 1 meter to make the inner support bear the force steadily and stop the leakage in time.
拉森钢板桩支护内支撑安装注意事项:
Precautions for installation of inner support of Larsen steel sheet pile support:
a、要严格按设计内支撑数量安装;
a. It should be installed in strict accordance with the number of designed internal supports;
b、内支撑随抽水标高及时安装;
b. The internal support is installed in time with the pumping elevation;

c、安装内支撑时要严格控制焊缝质量;
c. During the installation of the inner support, the weld quality should be strictly controlled;
d、安装支撑应该考虑坑内施工工作需要合理安排位置。
d. The installation support should consider the construction work in the pit and arrange the position reasonably.
下面我们再介绍一下拉森钢板桩施工完毕后的内支撑拆除。
Next, we will introduce the removal of internal support after the construction of Larsen steel sheet pile.
钢板桩支护施工完成后,开始拆除内支撑。从下到上拆除时,考虑施工的安 全,易操作,利用抽砂回填法回填基坑,减小钢板桩受力程度。首先在围堰内抽砂回填至第3层的框架下0.2m处,然后拆除第3层的内支撑。依次围堰内抽砂回填至第2层的框架以下0.2m,拆除第2层的内支撑。第2层的内支撑拆除完之后,然后是拆除第 1层。待内支撑完全拆除后,就可以开始拔桩了。
After the steel sheet pile support construction is completed, the internal support is removed. When demolishing from bottom to top, considering the safety of construction and easy operation, the foundation pit is backfilled by sand pumping and backfilling method to reduce the stress degree of steel sheet pile. Firstly, sand is pumped and backfilled to 0.2m under the frame of the third layer in the cofferdam, and then the inner support of the third layer is removed. The sand in the cofferdam is pumped and backfilled successively to 0.2m below the frame of the second layer, and the inner support of the second layer is removed. After the internal support of the second layer is removed, the first layer is removed. After the internal support is completely removed, the pile can be pulled out.
以上就是关于拉森钢板桩支护内支撑安装的介绍了,希望能对您有所帮助。
The above is about the installation of Larsen steel sheet pile support, hope to help you.
