According to the slope supporting and fixing method in the deep foundation pit construction process, lime powder is used for scattering a line in the first step, so that excavation can be conducted at any time according to the line when a large project is conducted, operation is convenient, and cost is low. In the second step, the pile groups form a plane structure, so that swinging of the engineering piles can be reduced, and the situation that the engineering piles in the slope area of the foundation pit are likely to incline and break due to the influence of the slope of the soil body of the foundation pit is avoided. The piles in the slope area are connected through the plane connecting frames arranged in a layered mode, so that the piles in the slope area form an integral structure, swinging of the engineering piles is reduced, the situation that the engineering piles in the foundation pit slope area are prone to inclining and breaking due to the fact that the engineering piles are affected by the slope of a foundation pit soil body is avoided, and the integrity of the foundation pit slope engineering piles in the construction process can be guaranteed; the construction progress and quality are guaranteed, and the problem that in the foundation pit excavation process, due to instability and landslide of the slope soil body, engineering piles in the foundation pit slope area are broken is solved.
本发明公开了一种深基坑施工过程中边坡支护固定方法，所述步骤一中使用石灰粉撒线，使得在进行较大的工程时，可以随时根据线进行开挖，操作方便且成本低。所述步骤二中群桩形成平面结构可以减少工程桩摆动，避免了基坑边坡区域的工程桩受基坑土体斜面影响是最容易出现倾斜，断桩。通过分层布置的平面连接架对边坡区域的群桩进行连接，使得群桩形成整体结构，减少工程桩摆动，避免基坑边坡区域的工程桩受基坑土体斜面影响是最容易出现倾斜、断桩，能保证基坑边坡工程桩在施工过程中的完整性，保证了施工进度与质量，解决了基坑开挖过程中由于边坡土体不稳定、滑坡，造成的基坑边坡区域工程桩断桩的问题。
