Cliff section tunnel side and front slope protection support erecting method
The invention discloses a cliff section tunnel side and front slope protection support erecting method. Different supports are erected according to the slope gradient, when the slope gradient is larger than 50 degrees, a double-row steel pipe scaffold is erected to serve as a working platform for slope protection engineering construction, and when the slope gradient is smaller than 50 degrees, a single-row steel pipe scaffold is erected to serve as a working platform for slope protection engineering construction; the double-row steel pipe scaffold adopts a profile steel grating as a scaffold construction platform foundation, the profile steel grating is composed of double-spliced I20 profile steel and I14 profile steel, one end of the double-spliced I20 profile steel is implanted into the slope body, the other end of the double-spliced I20 profile steel extends out of the slope body and is filled with M30 mortar, and the double-row steel pipe scaffold is connected with the slope body through a plurality of first wall connecting pieces; the single-row steel pipe scaffold adopts a vertical connecting steel bar as a scaffold foundation, the lower end of the vertical connecting steel bar is vertically fixed in the slope body, the exposed part of the vertical connecting steel bar is connected with a vertical rod of the single-row steel pipe scaffold, and the single-row steel pipe scaffold is connected with the slope body through a plurality of second wall connecting pieces.
本发明公开了一种悬崖地段隧道边仰坡防护支架搭设方法。其根据边坡坡度搭设不同的支架，当边坡坡度大于50°时，搭设双排钢管脚手架作为边坡防护工程施工的工作平台，当边坡坡度小于50°时，搭设单排钢管脚手架作为边坡防护工程施工的工作平台；双排钢管脚手架采用型钢格栅作为脚手架施工平台基础，型钢格栅由双拼I20型钢和I14型钢组成，双拼I20型钢一端植入坡体，另一端外伸出坡体并灌入M30砂浆，双排钢管脚手架通过若干第一连墙件与坡体连接；单排钢管脚手架采用竖向连接钢筋作为脚手架基础，竖向连接钢筋的下端竖向固定在坡体内，其外露部分与单排钢管脚手架的立杆连接，单排钢管脚手架通过若干第二连墙件与坡体连接。
