Excavation method and excavation device for hard rock layer of foundation pit
The invention discloses an excavation method and an excavation device for a hard rock layer of a foundation pit. The excavation method comprises the following steps: implementing positioning pay-off, and performing section, side slope, layered plane position and elevation pay-off on the foundation pit to be excavated; setting out according to positioning, and drilling along the vertical direction of the section to form a section vertical through seam; universal wheels are arranged at the intersection point of the side slope line and the elevation horizontal line of each layer and the opening of the side slope line correspondingly, and angle cutting of the side slope is conducted; a rope saw parallel guide rail is installed, a rope saw is wound on the universal wheel, and one end of the rope saw is arranged in the drilled hole; and the direction of the rope saw and the adjusting direction of the universal wheel are adjusted, and the hard rock layer in the pit foundation is cut. According to the excavation method, convenient and fast positioning construction and horizontal layered cutting can be achieved. The universal wheels are matched with the rope saw in a guiding mode for slope cutting, the slope construction effect and flatness are improved, the construction cost is reduced, the excavation effect of a hard rock layer in a foundation pit is improved, and the excavation time is shortened.
本发明公开了一种基坑硬质岩石层的开挖方法及开挖装置，开挖方法包括：实施定位放线，对待开挖基坑进行断面、边坡、分层平面位置和标高放线；按照定位放线，沿断面的垂直方向钻孔，形成断面竖向通缝；在边坡线与每层标高水平线交点处以及边坡线的开口处，分别设置万向轮，进行边坡的角度切割；安装绳锯平行导轨，将绳锯绕设在万向轮上，绳锯的一端设置在钻好的孔洞内；调试绳锯的方向和万向轮的调节方向，进行切割坑基内的硬质岩石层。本发明的开挖方法，有利于实现便捷、快速的定位施工和水平向分层切割。利用万向轮导向配合绳锯进行边坡切割，提高边坡施工功效及平整度，降低施工成本，提高基坑内硬质岩石层的开挖功效，缩短开挖时间。
