Embodiment Construction
[0018] The present invention will be further described below with reference to the drawings and specific embodiments.
[0019] Such as figure 1 with figure 2 As shown in the figure, the anchoring structure of the deformed slope includes steel pipe piles 1, which are arranged at intervals along the upslope side edge 9 of the deformed slope part 2, and the steel pipe piles 1 are located in the deformed slope part 2; also includes anchors 3, one end of the anchors 3 penetrates the slope cover 4 and then extends into the stable bedrock 5 for anchoring connection; each anchor 3 and at least one steel pipe pile 1 form an anchor Unit, each steel pipe pile 1 in each anchor unit is respectively connected to the anchor 3 in the anchor unit through a connecting piece 6, and one end of the connecting piece 6 and the corresponding steel pipe pile 1 penetrate the slope surface 7 The other end of the connecting piece 6 is connected with the end of the anchor 3 which penetrates from the slope ...

The invention discloses an anchoring structure of a deformed slope, belonging to the field of slope support engineering. The structure solves the problem of easy occurrence of bending deformation of the steel pipe pile or even complete failure of the anchoring structure caused by weak bending resistance of steel pipe piles and limited reinforcement effect on the slope. The steel pipe pile and an anchoring member are connected through a connecting member, and tension support is provided for the steel pipe pile through the anchoring function of the anchoring member, thus the end of each steel pipe pile inserted into the slope can be connected with the stable bedrock, and the end of the steel pipe pile penetrating from the slope surface can be connected with the anchoring member through the connecting member, so that the bending resistance performance of the steel pipe pile can be effectively improved, and the further deformation of the slope can be effectively controlled.
Description
Technical field [0001] The invention relates to the field of slope support engineering, in particular to an anchoring structure of a deformed slope. Background technique [0002] For slopes where the soil has been partially deformed, it is necessary to take certain reinforcement measures in the vicinity of the outside of the deformation range. Because this part of the slope is likely to be deformed, it must be anchored in time to prevent further expansion of the deformation range. . At present, the commonly used anchoring treatment method is to install steel pipe piles at intervals along the upslope side edge of the deformed slope part on the periphery of the deformed slope to prevent further deformation and expansion of the upper slope. Steel pipe piles have the characteristics of rapidness, simple construction conditions, and effectiveness; however, because only one end of the steel pipe pile inserted into the slope will be connected to the stable bedrock, and the exposed uppe...
