Detailed Description

For further explanation of the present invention, the following detailed description of the present invention is provided with reference to the drawings and examples, which should not be construed as limiting the scope of the present invention.

Example 1:

as shown in fig. 1 and 2, the built-in truss assembly type cylinder spliced pile comprises a pile body 11, circular walls 1 are arranged at two ends of the pile body, bolt holes 2 are uniformly arranged on the circular walls, a built-in truss 3 is arranged in the pile body 11, a semicircular protection sheet 5 is arranged at one corner of the built-in truss and surrounds an area for placing an inclination measuring pipe with the built-in truss, the semicircular protection sheet 5 is as high as the pile body, and the radius of the semicircular protection sheet 5 is larger than that of the inclination measuring pipe. The bottom end of the pile body is provided with four L-shaped protrusions 6, the top end of the pile body is provided with four grooves 4 matched with the L-shaped protrusions, and the depth of each groove is three times of the wall thickness of the circular wall. As shown in FIG. 4, adjacent spliced piles are connected through bolt holes and bolts 8 on the circular wall.

As shown in fig. 3, the built-in truss is as high as the pile body and comprises a plurality of cross bars 7 and inclined bars 12, the cross bars are welded on the inner wall of the pile body at intervals from top to bottom, three cross bars are arranged on the same plane to form a closed triangle, and the inclined bars 12 are arranged between the upper cross bar and the lower cross bar which are adjacent to each other. The built-in truss can strengthen the bending resistance and the shearing resistance of the pile body and increase the stability.

As shown in FIG. 5, the built-in truss assembly type cylinder splicing pile is spliced by a U-shaped splicing table 9, the table top of the U-shaped splicing table is U-shaped, a roller 10 is arranged on the table top, and the table top of the U-shaped splicing table cannot fall down when being used for stabilizing the cylinder to roll.
