Permanent and temporary combined type ground anchor and building method thereof

Abstract

The invention relates to the field of cable crane ground anchors, in particular to a permanent and temporary combined type ground anchor and a building method thereof. The combined type ground anchor comprises an anchorage structure and a plurality of pre-stressed anchor cables, the anchorage structure comprises a building pile foundation, and a plurality of pipe fittings, a plurality of pre-buried rods and a plurality of pre-buried plates are pre-buried in the anchorage structure; one end of the pre-stressed anchor cable penetrates through the pipe fitting and then is anchored to the anchorage structure, the other end of the pre-stressed anchor cable is anchored to the ground, the end of the pre-embedded rod penetrates through the pre-embedded plate and then extends out of the anchorage structure, the pre-embedded rod can be detachably connected with an anchoring end, and the anchoring end is used for being connected with a hoisting cable. The combined ground anchor construction method is simple, stable post-anchoring force is provided for a hoisting cable, a ground anchor structure which is stable in structure and convenient to construct is provided for mountainous areas where temporary ground anchors are difficult to arrange, the construction cost is saved, the construction period is shortened, the overall structural stability of an anchorage structure is achieved, and the hoisting safety is ensured.

Description

technical field [0001] The invention relates to the field of cable-suspended ground anchors, in particular to a combined ground anchor with permanent and permanent combination and its establishment method. Background technique [0002] The main types of existing ground anchors are pile-type ground anchors and gravity-type ground anchors, which are mainly temporary structures designed and constructed to provide post-anchor force during the construction process of large-scale hoisting and hoisting to ensure safety during hoisting and hoisting. . [0003] In the construction of highways in mountainous areas, especially in the construction of bridges such as arch bridges, suspension bridges and cable-stayed bridges, ground anchors need to be installed to complete the lifting construction. An effective working surface cannot be provided, and there is often no space for newly-built ground anchors as temporary structures. It takes a lot of manpower, material resources and time for...

Problems solved by technology

[0003] In the construction of highways in mountainous areas, especially in the construction of bridges such as arch bridges, suspension bridges and cable-stayed bridges, ground anchors need to be installed to complete the lifting construction. Unable to provide an effective working surface, and often do not have the space for new ground anchors as temporary structures, it takes a lot of manpower, material resources and time for the construction of ground anchors, resulting in higher construction costs and longer construction periods for bridges in mountainous areas

[0004] Therefore, there is an urgent need for a technical solution to solve the difficulties in setting ground anchors in mountainous areas, the inability to provide a stable rear anchor force for hoisting construction, and the technical problems that affect the construction cost and construction period in mountainous areas.
