Embodiment Construction

[0019] The present invention is further illustrated below by specific examples.

[0020] Such as figure 1 Shown, a kind of high-bearing-capacity pile comprises, upper pile body 1, lower pile body 2, load-bearing cutting block 3 buried in the soil, rotating lever connecting block 4, connecting bolt 5, pile core rotating disk 6, pile core 7 and pile core card Ring 8; one of them, the lower end of the upper pile body 1 is welded with a pile flange 101 for connecting with the lower pile body; the upper end of the lower pile body 2 is provided with a welding flange 201 for connecting the upper pile body 1; The lower end of the lower pile body 2 is provided with a pile point 202, which is convenient for piling into the soil; pile partitions 203 and 204 are welded near its two ends, and a grouting hole and a center hole are arranged on it, and a rotating pair is formed with the pile core 7; The body is provided with a hole of a specific shape, which is used to enter and exit the pil...

Abstract

The invention particularly relates to a high-bearing-capacity pile and a construction method thereof. The high-bearing-capacity pile is characterized by comprising an upper pile body (1), a lower pilebody (2), buried bearing cutting blocks (3), a rotating lever connection block (4), connection bolts (5), pile core rotating discs (6), a pile core (7) and a pile core clamping ring (8). The bearingcapacity and the stability of a pile body of the high-bearing-capacity pile are much greater than those of an ordinary pile; under the situation that the pile body needs to be pulled out, after the pile cutting blocks are recovered back into the pile body, the pile body is pulled out more easily; and under the situation that the same bearing capacity needs to be provided, the buried depth of the high-bearing-capacity pile is much smaller than that of an ordinary friction pile.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a high bearing capacity pile and a construction method thereof. Background technique [0002] Some steel piles or prefabricated concrete piles are mostly friction piles in soft soil areas. When the same bearing capacity is required, the piling depth of ordinary piles is much larger than the piles of this invention. pull out. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects, and provide a high-bearing-capacity pile whose bearing capacity and stability are far greater than ordinary piles and which can be pulled out more easily when the pile is cut into pieces and retracted behind the pile. [0004] In order to achieve the above object, the present invention is achieved in that: [0005] A pile with high bearing capacity, comprising: an upper pile body, a lower pile body, a soil-burdened load-bearing cut bl...
