Abstract
The invention discloses a method for constructing a cliff scaffold platform, and belongs to the field of building plank construction. The method comprises the following steps of: overhanging a section of frame beam at the initial section of the constructed scaffold platform and in the to-be-extended direction of the scaffold platform; drilling a group of anchor rod down holes required for the mounting extended section of the scaffold platform by using a rock down-hole drill; arranging heavy-load detachable composite functional anchor rods (26) in the anchor rod down holes, and fixing frame rods (31) and upright rods (27) to construct the extended section of the scaffold platform; and butting a section of guide rail (28) with corresponding length on the extended section of the scaffold platform, opening bolts connected on the guide rail (28) on the lower part of a connecting plate (30), and pushing the frame beam along the guide rail so that the frame beam extends the next section in the to-be-extended direction of the scaffold platform. The scaffold platform can bear heavy load without a ground support or a peak suspension rod; and due to overhanging type construction, the extended direction can turn left and right and pitch with variable angle along with the shape of a mountain.
Description
Technical field
A kind of building method of overhanging cliff scaffolding platform belongs to building plank road construction field.Be specifically related to a kind of building method of overhanging cliff scaffolding platform.
Background technology
The plank road construction technology has been achieved the steep cliff plank road of one of three invention on China's ancient building history, the ancient plank road construction methods such as intercept water boat-carrying construction method, high-altitude suspension cable, cage construction method that adopt realize more, and along with the progress of modern science and technology, the progress of plank road construction technology is but also unsatisfactory.Intercept water the boat-carrying construction method because of being subjected to its essential condition---the restriction of water, be not suitable for the construction of anhydrous place; High-altitude suspension cable, cage construction method, even the auxiliary of helicopter arranged, some highly difficult engineering still can't be carried out construction, and suspension cable construction damages easily to natural environment, and particularly some vegetation in thousand sustains damage, be difficult to recover, at present, world-renowned certain mountain " West Coast plank road " that China is domestic, the long number km is suspended on 1500 meters high cliffs of cutter as cutting, because be subjected to the restriction of construction technology, band shape and many precious vegetation that can only build up horizontal extension damage to some extent.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provide a kind of not by ground supports, not by the mountain top suspension cable, can take the weight and carry, overhanging type is built, can construct continuously, bearing of trend can be followed about the shape on mountain and be turned to, the building method of a kind of overhanging cliff scaffolding platform of pitching angle.
