Problems solved by technology

[0002] Existing vertical channel construction generally uses a combination of various mechanical equipment such as scaffolding, derricks, and trusses, and is built from bottom to top. These equipments have shortcomings such as large amount of materials, long installation period, and limited erection height, so they cannot be popularized and applied. The applicable vertical passages of this method are generally limited to high-rise buildings in plain areas, and the height of buildings is generally abou

Example Embodiment

[0033] Example 1

[0034] A construction method for high-altitude vertical manned passage in high mountain rock area, including:

[0035] S1. Set the front fulcrum 1 close to the cliff and the rear fulcrum 2 far away from the cliff. The front fulcrum 1 and the rear fulcrum 2 are formed by pouring concrete; excavate the foundations of the front fulcrum 1 and the rear fulcrum 2; the front fulcrum 1 The excavation slope ratio to the rear support point 2 is both 1:1, and the bottom of the corresponding support point is excavated to fall on the complete rock surface; the composite steel formwork is used to pour the concrete, and after curing to the design strength, the front support point 1 and the back Pivot 2

[0036] S2. A rear anchor embedded part is provided on the rear fulcrum 2; the spliced ​​double beret beams 3 are used as the main body, and the Beret beams are assembled in the direction from the front fulcrum 1 to the rear fulcrum 2, here from the front fulcrum 1 to the rear fu...

Abstract

The invention discloses a construction method of a high-altitude vertical manned passage in a high mountain rock area, which comprises the following steps of: arranging a front fulcrum close to a cliff and a rear fulcrum far away from the cliff, and molding the front fulcrum and the rear fulcrum by pouring concrete; adopting a double-truss bailey beam as a main body, sequentially assembling the bailey beams from a front fulcrum to a rear fulcrum, and enabling one end of each bailey beam to extend out of a cliff to form a cantilever; reserving a lifting portal frame opening of the hanging basket in the cantilever end of the bailey beam, and installing the hanging basket at the lifting portal frame opening. The equipment material consumption is small, the mounting period is short, the erecting height is not limited, the construction cost can be effectively saved, the limitation of the height and the actual foundation condition is avoided, and the structure is stable.

Description

technical field [0001] The invention relates to the technical field of architectural engineering in natural scenic spots. More specifically, the present invention relates to a construction method for high-altitude vertical manned passages in alpine rock areas. Background technique [0002] Existing vertical channel construction generally uses a combination of various mechanical equipment such as scaffolding, derricks, and trusses, and is built from bottom to top. These equipments have shortcomings such as large amount of materials, long installation period, and limited erection height, so they cannot be popularized and applied. The applicable vertical passages of this method are generally limited to high-rise buildings in plain areas, and the height of buildings is generally about 90m; [0003] However, in natural development scenic spots, especially mountainous karst landform scenic spots or tiankeng scenic spots with obvious landform features and large height differences,...
