Description

Technical Field

[0001] The utility model relates to the technical field of caisson construction equipment, in particular to a caisson anti-tilt device. Background Art

[0002] Caissons are often used in municipal engineering. Correction is a common problem in caisson construction. During the sinking process, the caisson often tilts due to differences in surrounding friction and construction factors. The larger the area and the deeper the caisson, the more difficult it is to correct the deviation.

[0003] At present, there are two main methods commonly used to correct caissons: biased digging and straightening. The correction device usually acts on a point in the caisson, which often causes the caisson to have a large deflection during correction or is difficult to correct, and the correction period is long. At the same time, it is not applicable to caissons of different specifications. In view of the above problems, it is urgent to design a device that can prevent the caisson from tilting during the sinking process. Utility Model Content

[0004] In order to solve the above technical deficiencies, the utility model provides a caisson anti-tilt device, which can effectively prevent the caisson from tilting during the sinking process.

[0005] The utility model discloses an anti-tilt device for a caisson, comprising a horizontally arranged annular base, a retaining edge is arranged on the outer side of the upper end surface of the annular base, a plurality of vertical guide sleeves are evenly arranged on the inner side of the annular base, the guide sleeve is connected to the annular base by a connecting piece, a guide tube is slidably arranged in the guide sleeve, a mounting seat is arranged on the upper end of the guide tube, a hemispherical concave is arranged on the bottom of the mounting seat, an insertion rod is arranged in the guide tube, the length of the insertion rod is greater than the length of the guide tube, a sphere is arranged on the upper end of the insertion rod, the sphere is rotatably embedded in the hemispherical concave, threaded holes are evenly arranged on the circumferential direction of the side wall of the guide tube between the guide sleeve and the mounting seat, adjusting bolts are arranged in the threaded holes, and the adjusting bolts are pressed against the insertion rod in the guide tube.

[0006] When the above device is in use, the annular base and the connecting piece are disassembled, a mounting hole is vertically drilled on the foundation, the insertion rod and the conduit are inserted downward into the mounting hole, and when the lower end of the insertion rod contacts the bottom of the mounting hole, the insertion rod is further inserted downward into the foundation for fixation, and the conduit is located in the mounting hole, and a gap is left between the side wall of the conduit and the inner wall of the mounting hole. The conduit is adjusted by adjusting the bolts so that the conduit is completely in a vertical state, and then the annular base and the guide sleeve are connected by the connecting piece, and the caisson is placed on the annular base and fixed by the retaining edge, thereby preventing the caisson from tilting during the sinking process.

[0007] Among them, the connecting piece and the guide sleeve are fixedly connected, a through hole No. 1 is vertically arranged on the connecting piece, and a through hole No. 2 is arranged at a position corresponding to the through hole No. 1 on the annular base. The through hole No. 1 is in an elongated shape and its direction is arranged along the radial direction of the guide sleeve. The annular base and the connecting piece are fixed by through hole No. 1, through hole No. 2, fastening bolts and fastening nuts. The through hole No. 1 is in an elongated shape, which increases the adjustable range and facilitates the connection between the annular base and the connecting piece.

[0008] The utility model provides an anti-tilt device for caisson, which has the beneficial effects of inserting a rod into the foundation to play a fixing role, adjusting the bolt to make the guide tube completely in a vertical state, connecting the annular base with the guide sleeve through a connecting piece, so that the annular base can only move in the vertical direction, fixing the caisson on the annular base, and preventing the caisson from tilting during the sinking process.
