Abstract

The invention belongs to the technical field of building profile steel supporting, and particularly discloses a profile steel supporting pile which comprises a supporting pile body and drilling locating units; stepped hole cavities are uniformly formed in the supporting pile body; the drilling locating units are arranged in the stepped hole cavities; protection sleeves are arranged in the steppedhole cavities; supporting cores are inserted in the protection sleeves; the bottom ends of the supporting cores are connected with rotating core rods; locating blocks are arranged at the bottom ends of the supporting cores; spiral grooves are formed in the rotating core rods; rotating columns are arranged at the bottom ends of the protection sleeves, and are in rotational fit with the spiral grooves; core-bit sleeves are connected with the bottom ends of the protection sleeves; bottom drill bits are connected with the bottom ends of the rotating core rods by means of sliding blocks; torsionalsprings sleeve the bottom drill bits; and alloy steel balls are arranged at the bottom ends of the bottom drill bits. The drilling locating units are arranged on the supporting pile body, the bottom drill bits can be impacted and crushed on the outer surface of a rock, and a locating effect on the supporting pile body can be realized.

Description

technical field [0001] The invention belongs to the technical field of building section steel support, in particular to a section steel support pile. Background technique [0002] Foundation pit support is to take protective measures to support and reinforce the foundation pit wall in order to ensure the construction of underground structures and protect the safety of the surrounding environment of the foundation pit. In foundation pit support engineering, when the excavation is deep or the foundation pit without grading conditions is usually supported, various types of support piles are used. At present, the types of supporting piles generally adopt cast-in-place piles, prefabricated concrete piles, ordinary section steel, steel sheet piles and other supports. [0003] And existing section steel support pile is in use, if use in some rocks or the area that cobblestone geology is more, because the foundation of pebble or rock is comparatively hard, when needing section stee...
