Assembly type elastic damping anchorage device suitable for high-intensity area and construction method thereof

Abstract

The invention discloses an assembly type elastic damping anchorage device suitable for a high-intensity area and a construction method of the assembly type elastic damping anchorage device. The assembly type elastic damping anchorage device comprises an anchorage base which is of a cylindrical structure and is formed by assembling a plurality of fan-shaped cushion blocks, grooves and protruding blocks are arranged on the two sides of each fan-shaped cushion block correspondingly; first cavities are formed in the protruding blocks, springs connected with the protruding blocks are arranged in the first cavities; and the fan-shaped cushion blocks are provided with conical anchor plate holes, clamping pieces are arranged in the anchor plate holes, second cavities filled with elastic damping are annularly reserved between the interior of the anchor plate holes and the clamping pieces, and a space between the elastic damping and the clamping pieces is filled with hydraulic oil. According tothe assembly type elastic damping anchorage device suitable for the high-intensity area and the construction method of the assembly type elastic damping anchorage device, elastic damping is adopted, the bearing capacity of the elastic damping is large, the service life of the elastic damping is long; the fan-shaped cushion blocks with the grooves and the protruding blocks are adopted for assembling the anchor base, the cushion blocks of different numbers and different radiuses can be selected according to actual conditions, the number of needed anchor base holes and the size of the needed anchor plate holes can be conveniently adjusted; and the assembly type anchorage device does not bring excessive additional load to the structure, is convenient to construct and wide in application range,can protect the clamping pieces from being damaged, and is reliable in anchoring performance.

Description

Technical field [0001] The invention belongs to the technical field of engineering anchors and energy dissipation devices in high-intensity areas, and particularly relates to an assembled elastic damping anchor suitable for high-intensity areas and a construction method thereof. Background technique [0002] The anchoring system can increase the stability of the supporting structure or the rock and soil. Commonly used anchors have the advantages of good construction and installation effects, high work efficiency, and fast progress. They are mainly used in bridge engineering, tunnel engineering, rock slope protection and anchoring, foundation reinforcement, etc. field. There are many types of anchors, such as round anchors, porous clip anchors, and steel cone anchors. However, for the high-intensity earthquake area, due to the particularity of the region, the anchoring method and the form of anchors currently used are still relatively simple, mainly using clip-type anchors, that ...

Problems solved by technology

However, for high-intensity earthquake areas, due to the particularity of the region, the anchoring methods and anchorage forms currently used are still relatively simple, and clip-type anchorages are mainly used, that is, the anchorage is mainly composed of clips and anchor plate holes. provide binding capacity

The advantage of this kind of anchorage is that the anchoring failure of any anchor rod or steel strand will not cause the failure of the whole bundle of anchorage, and the number of steel strands in each bundle is not limited, but the disadvantage is that the end of the component needs to be Reaming, and its controllable strength and flexibility are low, so it cannot adapt to anchoring under multi-scenario conditions

Moreover, because the anchor plate hole and the splint are rigid structures, the anchor rod or steel bar is prone to breakage under strong earthquakes or large loads.

In addition, since the inner diameter and thickness of the anchor plate holes used by each anchor rod and steel strand are different, resulting in a small amount of anchor construction and installation, low efficiency, and a large drilling workload, the existing slope engineering uses It is also difficult to apply the anchorage system in many different situations, so it is necessary to develop an elastic damping anchorage suitable for various situations
