Deep foundation pit slope reinforcing method
The invention discloses a deep foundation pit slope reinforcing method which is characterized by comprising the steps that firstly, after surface cleaning, paying off is conducted according to a design drawing, a ground beam boundary line, a hardening boundary line and a plurality of cast-in-place pile positioning hole lines are included, the hardening boundary line is located on the outer side of the ground beam boundary line, and the cast-in-place pile positioning hole lines are located on the inner side of the ground beam boundary line; the guide rails are arranged at equal intervals in the circumferential direction; secondly, a ground beam groove is dug along the ground beam boundary line, and a cast-in-place pile positioning hole is dug along the cast-in-place pile positioning hole line; thirdly, a ground beam reinforcement cage is placed in the ground beam ditch, a cast-in-place pile reinforcement cage is placed in the cast-in-place pile positioning hole, and the top of the cast-in-place pile reinforcement cage is connected with the ground beam reinforcement cage through connecting steel bars; fourthly, a ground beam and a cast-in-place pile are poured, and earth surface hardening is conducted; and fifthly, the foundation pit is excavated in a layered mode, and a layer of soil retaining plate is additionally installed between every two adjacent cast-in-place piles when each layer is excavated. The method has the advantages of being high in supporting strength, good in construction safety, free of occupying the bottom space of the foundation pit and the like.
本发明公开了深基坑边坡加固方法，其特征在于，包括：步骤一、地表清表后，按照设计图纸放线，包括地梁界线、硬化界线和多个灌注桩定位孔线，其中，硬化界线位于地梁界线的外侧，多个灌注桩定位孔线位于地梁界线的内侧，并沿其周向等间隔设置；步骤二、沿地梁界线挖掘地梁沟，沿灌注桩定位孔线挖掘灌注桩定位孔；步骤三、在地梁沟内放置地梁钢筋笼，在灌注桩定位孔内放置灌注桩钢筋笼，并将灌注桩钢筋笼的顶部与地梁钢筋笼通过连接钢筋连接；步骤四、浇筑地梁、灌注桩，并进行地表硬化；步骤五、分层对基坑进行挖掘，每挖掘一层，在相邻所述灌注桩之间加装一层挡土板。本发明具有支护强度高、施工安全性好、不占用基坑底部空间等优点。
