[0005] A pile foundation casing which is anti-slip, falling and sinking comprises a plurality of support rods which are evenly arranged along the circumferential direction of the casing, and a positioning mechanism for radially positioning the casing is provided on the support rods.

[0006] Furthermore, the positioning mechanism comprises a through hole arranged on the support rod and a support plate arranged in the through hole, and the outer side surface of the support plate is an inclined surface inclined inward from top to bottom.

[0007] Furthermore, the through hole is a vertical rectangular through hole.

[0008] Furthermore, a baffle is provided on the upper end of the support plate.

[0009] Furthermore, the positioning mechanism comprises a nut which is arranged on the support rod and threadedly connected to the support rod, and a support plate is provided at one end of the outer side of the nut.

[0010] Furthermore, the support rod is provided with a scale.

[0012] 1. The utility model includes a plurality of support rods evenly arranged along the circumferential direction of the casing, and a positioning mechanism for radially positioning the casing is provided on the support rods. During the construction process, the support rods are supported on the ground, which can effectively prevent the casing from being displaced and sinking, greatly reducing the number of casing verifications, shortening the drilling time of bored piles, and effectively avoiding the situation of hole collapse due to waiting for verification during the drilling process, reducing the input of personnel and machinery, and the device effectively improves the progress of on-site pile foundation construction. The axial direction of the casing is positioned by the positioning mechanism to prevent the casing from being offset during construction, and the stability is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1As shown, a pile foundation casing that prevents slipping and sinking includes a plurality of support rods 2 evenly arranged along the circumferential direction of the casing 1, and a positioning mechanism for radially positioning the casing 1 is provided on the support rods 2. During the construction process, the support rods 2 are supported on the ground, which can effectively prevent the casing from being displaced and sinking, greatly reducing the number of casing checks, shortening the drilling time of bored piles, and effectively avoiding the situation of hole collapse due to waiting for verification during the drilling process, reducing the investment in personnel and machinery, and the device effectively improves the progress of on-site pile foundation construction. The axial direction of the casing 1 is positioned by the positioning mechanism to prevent the casing 1 from being offset during construction, and the stability is good.

[0021] like Figure 1 and Figure 2 As shown, the positioning mechanism includes a through hole arranged on the support rod 2 and a support plate 3 arranged in the through hole. The outer side surface of the support plate 3 is an inclined surface inclined inward from top to bottom. After the casing 1 is installed, the support plate 3 is inserted into the through hole, and the lower end of the support plate 3 penetrates into between the casing 1 and the inner wall of the foundation pit, thereby correcting the inclination of the casing 1 and making it close to the casing, with good stability and simple and convenient operation.

[0022] The through hole is a vertical rectangular through hole.
