Embodiment Construction

[0031] like figure 1 and figure 2 A new type of anchor head structure for slope support is shown, including: a reinforced concrete pier 1 and a sealing anchor body;

[0032] The anchor body includes: steel backing plate 2, anchor head 3, cast-in-place concrete panel 5 and anchor cable 7;

[0033] Wherein, the anchor cable 7 is penetrated in advance in the anchor hole 6 laid on the side slope, and after the anchor cable 7 penetrates the anchor hole 6, the anchor cable 7 is extended into the end and fixed by pouring grout;

[0034] The cast-in-place concrete panel 5 is arranged on the outer wall of the slope, wherein the anchor cable 7 runs through the cast-in-place concrete panel 5;

[0035] The reinforced concrete pier 1 is set on the outer wall of the cast-in-place concrete panel 5, and the anchor cable 7 also runs through the reinforced concrete pier 1, wherein the reinforced concrete pier 1 has two layers of main reinforcements built in;

[0036] The reinforced concrete...

Abstract

The invention discloses a novel anchor head structure used for slope support. The structure comprises a reinforced concrete support and an anchor sealing body. The anchor sealing body comprises a steel cushion plate, an anchor head, a cast-in-place concrete panel and an anchor cable. The reinforced concrete support is arranged on the outer wall of the cast-in-place concrete panel, wherein the reinforced concrete support is internally provided with a load-bearing main rib. The reinforced concrete support is a regular trapezoid platform. The steel cushion plate is arranged on the outer wall of the reinforced concrete support, wherein the anchor cable extends out of the tail end of the steel cushion plate and is fastened by the anchor head. The external of the reinforced concrete support is provided with an outer cover which covers the anchor head, the steel cushion plate, and the reinforced concrete support. The inner wall of the outer cover is provided with a reinforcing steel mesh lining. Using the technical scheme, the invention provides a brand new anchorage device fixing mechanism, and through collocation of the concrete and the reinforcing steel mesh, a more steady protection system is formed.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a novel anchor head structure for slope support and a construction method thereof. Background technique [0002] At present, the general anchor head only uses backing plate or channel steel as the compressive bearing body, and there is no steel mesh protection. Although the construction is simple, the durability is not high, and it is easy to cause the concrete to fall off, the anchor head is exposed, etc., so that The relaxation of prestress brings great hidden danger to the safety of the slope. Therefore, the traditional manufacturing method has disadvantages such as low durability and low safety. Contents of the invention [0003] Aiming at the above technical problems, the present invention proposes a novel anchor head structure for slope support and its construction method to solve the current shortcomings of low durability and low safety in the manufacture of anch...
