Foundation pit support method for expansion construction from deep foundation pit to shallow foundation pit
The invention relates to the technical field of foundation pit support, and discloses a foundation pit support method for expansion construction from a deep foundation pit to a shallow foundation pit, which comprises the following steps: S1, construction preparation; s2, construction site treatment; s3, pipe piles are pre-buried; s4, mounting a supporting protection plate; s5, the junction of the shallow foundation pit and the deep foundation pit is reinforced; and S6, enclosure is completed. The embedded rod is arranged at the bottom of the prefabricated pipe pile, so that the prefabricated pipe pile can be conveniently embedded, and the first barb and the second barb are arranged outside the prefabricated pipe pile, so that the mounting stability of the prefabricated pipe pile is better, and the construction efficiency of the prefabricated pipe pile is effectively improved; and secondly, a supporting protection plate is arranged between the two prefabricated pipe piles, the connecting stability of the supporting protection plate, the deep foundation pit and the shallow foundation pit can be improved through a first inserting rod and a second inserting rod, meanwhile, mortar is poured into the supporting protection plate, and therefore the junction of the shallow foundation pit and the deep foundation pit can be well supported and maintained.
本发明涉及基坑围护技术领域，公开了一种深基坑向浅基坑的扩展施工的基坑围护方法，S1、施工准备；S2：施工现场处理；S3、预埋管桩；S4、安装支撑防护板；S5、加固浅基坑与深基坑的交界处；S6、完成围护。本发明首先在预制管桩的底部设置有嵌入杆，这样可便于预制管桩的埋入，并且在预制管桩的外部设置有第一倒刺和第二倒刺，这样能够使得预制管桩安装的稳定性更好，有效的提高其施工效率，其次在两个预制管桩中间设置有支撑防护板，利用第一插杆与第二插杆可提高支撑防护板和深基坑与浅基坑的连接稳定性，同时在支撑防护板的内部灌入砂浆，这样能够使得对浅基坑与深基坑的交界处提供很好的支撑维护的作用。
