Detailed Description
The technical solution of the present invention is further explained with reference to the drawings and the embodiments.
In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the utility model and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the utility model.
As shown in fig. 1 and 2, the embodiment provides a karst pile foundation casing, which includes at least two sections of cylinders 1, where the number of the cylinders 1 is configured as needed (specifically, the deeper the foundation pit 2 is, the more the number is set), and particularly, in the embodiment, the cylinder 1 located at the uppermost layer exceeds the ground (the cylinder 1 located at the uppermost layer is not shown), so that the stability of the karst pile foundation is better, where an upper end of each cylinder 1 is fixedly provided with a snap ring 3, an inner diameter and an outer diameter of the snap ring 3 are respectively greater than an inner diameter and an outer diameter of the cylinder 1, an outer diameter of the snap ring 3 is smaller than the inner diameter of the foundation pit 2, and a lower end of another cylinder 1 is snapped into the snap ring 3;
pile foundation protects a section of thick bamboo and still includes the locating lever 4 that couples together snap- fit ring 3 and 1 lower extreme of another barrel to and set up 1 outer being used for making barrel 1 and 2 inner wall fixed position sleeve 5 of foundation ditch with locating lever 4 cooperation, the position sleeve 5 is embedded to in 2 inner walls of foundation ditch, specifically, locating lever 4 is the screw rod, and position sleeve 5 is the swivel nut supporting with the screw rod.
In the embodiment, the barrel bodies 1 can be easily placed in the foundation pit 2, the barrel bodies 1 are stacked through the matching of the clamping rings 3 and the barrel bodies 1, the adjacent two barrel bodies 1 are not easy to be dislocated, and meanwhile, the barrel bodies 1 and the inner wall of the foundation pit 2 are fixed together through the positioning rods 4 and the positioning sleeves 5, so that the problem that the pile casing is deviated in the foundation pit 2 is effectively solved; in order to make the intensity of pile foundation better, barrel 1 and snap ring 3 in this embodiment all adopt the steel sheet material to make, and wherein the lower extreme of snap ring 3 and barrel 1 is provided with the through-hole 6 that supplies locating lever 4 to pass respectively, and locating lever 4 can with through-hole 6 threaded connection, also can be the slip and pass, mainly makes the relative position between barrel 1 and snap ring 3 and the foundation ditch 2 can fix.
