Cantilever beam structure of antique plank road along cliff and construction technology thereof

Abstract

The invention discloses a cantilever beam structure of an antique plank road along a cliff and a construction technology thereof. The cantilever beam structure is formed by an H-type steel assembly, and a rock bolt assembly fixedly anchored on the rock wall of a mountain in a combining way, wherein the H-type steel assembly is formed by the combination of a steel backing plate (2) and H-type steel (3); the H-type steel (3) is welded on the steel backing plate (2) vertically and serves as the supporting beam of a road panel (7) of the antique plank road along the cliff; the rock bolt assembly is formed by the connection of rock bolts (1), bolts and nuts; and the rock bolts (1) are welded with the bolts in a surfacing manner. The construction technology of the cantilever beam structure is as follows: ensuring the position of the cantilever beam according to the design graph paper; eliminating the weathering surface and fractured rock mass of the locating-point rock surface, and scabbling and leveling; ensuring the length of the rock bolts (1) and drilling holes in the rock bolts; filling cement mortar into the rock bolt holes and inserting the rock bolts (1) welded with anchor heads; mounting the H-type steel assembly on the rock bolts after the cement mortar is solidified to a degree of the designed strength; and fastening with bolts. The cantilever beam structure is safe and reliable in structure, simple and convenient in construction technology, quick in speed, low in engineering cost, and good in simulating of the style of the antique, and is suitable for application along the cliff.

Description

technical field [0001] The invention relates to the basic construction of an antique plank road, in particular to the supporting structure and construction technology of the antique plank road, which is used to build an antique plank road and a landscape plank road on cliffs, and the formed antique plank road can be used for tourists to walk, which can meet the requirements of danger, steepness and , Strange landscape effect, but also meet the design safety requirements. Background technique [0002] The cantilevered beams of the ancient plank road are the cantilevered structural part of the plank road that the predecessors used manpower to chisel out a rock nest with a slightly larger diameter than the inserted hardwood (generally, the diameter of the hole is greater than 300mm, and the hole depth is greater than 1m), and then inserted into the thick hardwood. Most of the ancient plank roads use anti-corrosion wood, such as sylvestris pine and camphor wood. However, for o...
