Embodiment Construction

[0030] see Figure 1 to Figure 5 , the oblique control grouting steel anchor pipe frame of the present invention is composed of seven parts such as a frame beam 1, a steel anchor pipe 3, an anchor pipe hole 4, a primary grouting pipe 8, a centering ring 7, a grouting body, and a steel backing plate 10. .

[0031] 1) Frame Beam 1

[0032] The frame beam 1 is composed of reinforced concrete beams 11 and vertical ribs 12 (grid shape), fixed on the surface of the slope 15, and mainly plays the role of surface slope consolidation and transmission of landslide thrust to deep anchors.

[0033] 2) Steel anchor pipe 3

[0034] The steel anchor pipe 3 is the main force-bearing member, relying on its own tensile strength to resist landslide thrust. Generally, 6m long, Φ51×5mm seamless steel pipe is used, which can be lengthened or shortened according to the needs of the project. Set the secondary grouting hole 6 in the steel anchor pipe 3 of the control grouting part, and the diamete...

Abstract

Provided are a slant grouting control steel anchor pipe frame and a construction method thereof. A primary grouting body is poured to the peripheral space of a steel anchor pipe through a primary grouting pipe; after the primary grouting body is solidified, a secondary grouting body is poured to the outside through a secondary grouting hole in the steel anchor pipe wall in a compression mode, the secondary grouting body splits the primary grouting body through the secondary grouting hole and is diffused to a peripheral rock and earth mass and forms a mixed grouting body with the primary grouting body. A concrete beam is poured along a slope to wrap the top of the steel anchor pipe in the beam. The slant grouting control steel anchor pipe frame combines the advantages of an anchor rod frame and a grouting control technology, the steel anchor pipe is used as a protection measure and a secondary grouting channel, and by means of improvement of the strength of the peripheral rock and earth mass through the secondary grouting, a steel pipe and the peripheral rock and earth mass form a whole body to defend a slope together. A slant grouting control steel anchor pipe frame structure has the advantages of being advanced in technology, reasonable in economy, fast in construction and the like and is a novel slope reinforcing technology with good developing prospects.

Description

technical field [0001] The invention relates to an oblique control grouting steel anchor pipe frame and a construction method thereof, which are suitable for side slope reinforcement projects of roads, railways, mines, and municipalities. Background technique [0002] The anchor rod in the anchor rod frame uses steel bars or steel pipes, mainly relying on the pull-out force to resist the thrust of the landslide; in addition to the role of surface slope consolidation, the frame beam also plays the role of transmitting the anchoring force to the slope body. As a traditional slope reinforcement technology, the anchor frame has limited anti-sliding ability and is mostly used for shallow landslide control. Contents of the invention [0003] The object of the present invention is to provide an obliquely controlled grouting steel anchor pipe frame to solve the problem of limited anti-sliding ability in the prior art of traditional slope reinforcement technology. [0004] The tec...
