Larsen steel sheet pile and construction method thereof
The Larsen steel sheet pile comprises a steel sheet pile body, the steel sheet pile body comprises a first steel sheet body, a second steel sheet body and a third steel sheet body, the first steel sheet body, the second steel sheet body and the third steel sheet body are integrally connected, and grouting channels are formed in the middle positions of the two side edges of the second steel sheet body. The grouting device has the beneficial effects that the bottom of the grouting channel is conical, the whole grouting channel is in a triangular pyramid shape, the contact area between the grouting channel and soil is small, soil side mold resistance and end resistance generated in the downward insertion process of the steel sheet pile are small, downward insertion of the steel sheet pile is not affected, a pipeline in the bottom of the grouting channel is gradually necked down and similar to the effect of a one-way valve, and meanwhile the end resistance can be reduced; when the steel sheet pile is lifted, grouting can be conducted through connection of the grouting pipeline and an external pipeline, gaps between soil bodies pulled out of the steel sheet pile are filled, and the influence on the surrounding soil bodies and buildings is reduced.
本发明公开了一种拉森钢板桩及其施工方法，包括钢板桩本体，钢板桩本体包括第一钢板体、第二钢板体和第三钢板体，第一钢板体、第二钢板体和第三钢板体一体式连接，第二钢板体两侧边中间位置均设置有注浆通道。本发明有益效果：本发明注浆通道底部为锥形，整体呈三棱锥形状，与土体接触面积小，在钢板桩下插过程中产生的土侧模阻力及端阻力小，并不影响钢板桩的下插，注浆通道的底部内管道逐渐缩颈，类似于单向阀作用，同时可减小端阻力；在提升钢板桩的同时，可通过注浆管道与外部管道连接进行注浆，填充钢板桩拔出的土体间空隙，减小对周边土体及建筑的影响。
