Embodiment 1
[0035] A structure that limits the horizontal displacement of pile foundations in a deformed rock formation, such as figure 1 and figure 2 As shown, it includes a first casing 1 , a second casing 2 and a third casing 3 arranged on the outer periphery of the pile foundation 7 . Wherein, the radius of the third casing 3 is greater than the radius 18 centimeters of pile foundation 7 design sections (considering the influence of foundation construction error), the radius of the second casing 2 is greater than the radius 20 centimeters of the third casing 3, the first casing The radius of 1 is greater than the radius 30 centimeters of the second casing 2. The bottoms of the first casing 1 , the second casing 2 and the third casing 3 exceed the bottom of the deformed rock formation 8 and are anchored into the non-deformed rock formation 9 .
[0036] Such as figure 1 and figure 2 As shown, anti-deformation concrete 4 is filled between the first casing 1 and the second casing 2....
