Specifically, as shown in fig. 4, the bottom end of the toggle block 7 of the section steel support pile is provided with an elastic metal layer, the top end of the toggle block 7 is provided with a wear-resistant metal layer, and the wear-resistant metal layer is provided with a water inlet 71; the interior of the toggle block 7 is of a cavity structure, a push plate 72 is arranged in the toggle block 7 in a sliding manner, water-absorbing expansive soil is arranged on the upper surface of the push plate 72, and raised spines 73 are arranged on the lower surface of the push plate 72; the elastic metal layer is provided with a convex thorn hole 74, and the convex thorn hole 74 is matched and spliced with the convex thorn 73; when the device works, the elastic metal layer is arranged to facilitate the pushing block 5 to quickly separate from the shifting block 7 when the pushing block 5 moves upwards; after the inserting column 6 is continuously pushed out from the inserting hole 12, the water inlet hole 71 formed in the shifting block 7 can absorb moisture in soil around the supporting pile body 1, so that the water-absorbing expansive soil is expanded, the expanded water-absorbing expansive soil can push the pushing plate 72 to move towards the elastic metal layer, so that the elastic metal layer is expanded, the convex thorns 73 are inserted out of the convex thorns holes 74, so that the supporting force of the inserting column 6 on the supporting pile body 1 is increased, and meanwhile, sludge around the inserting column 6 can be gathered around the inserting column 6, so that the supporting pile body 1 is supported, the supporting pile body 1 is prevented from being used in sludge soil, the supporting pile body 1 is prevented from being inclined due to external extrusion force, and the supporting effect of the supporting pile body 1 is further influenced.
Specifically, as shown in fig. 2 and 5, the torsion spring 27 of the section steel support pile of the present invention is uniformly sleeved with an elastic sleeve ring 8, and the outer wall of the elastic sleeve ring 8 is uniformly provided with hard bristles 81, and the elastic sleeve ring 8 is a hollow structure; the outer end part of the hard shaving 81 on one side wall of the elastic lantern ring 8 is contacted with the outer wall of the bottom drill bit 26, and the hard shaving 81 on the other side wall of the elastic lantern ring 8 is contacted with the inner side wall of the drill core sleeve 25; when the bottom drill bit works, when the torsion spring 27 extrudes and twists, the elastic sleeve ring 8 is driven to rotate, and then the hard hairbrush arranged on the rotating elastic sleeve ring 8 rotationally scrapes off soil adhered on the outer wall of the bottom drill bit 26 and soil adhered on the inner wall of the drill core sleeve 25, so that the phenomenon that the bottom drill bit 26 is difficult to rotate due to excessive soil and dust accumulated in the drill core sleeve 25 is prevented; the hollow structure's that sets up simultaneously the elastic sleeve ring 8 can make the elastic sleeve ring 8 according to the dynamics of the cohesive soil who strikes off, and then produce different deformations, and then prevent that the elastic sleeve ring 8 joint from to the cohesive soil in, and then influence end drill bit 26's operating condition.
Specifically, as shown in fig. 2 and 5, a dust exhaust cavity 31 is formed in the elastic metal sheet 3 of the section steel support pile, and a dust blowing hole 32 is formed in the top wall of the dust exhaust cavity 31; the bottom drill bit 26 is provided with an air guide groove 261, one end of the air guide groove 261 is communicated with the elastic lantern ring 8 of the cavity structure, and the other end of the air guide groove 261 is communicated with the dust exhaust cavity 31; when the elastic sleeve ring 8 of cavity structure produced the extrusion, the gas in the elastic sleeve ring 8 entered into dust exhaust chamber 31 through air guide groove 261, and then blown out the surface of elasticity gold piece through blowing dirt hole 32, and then cleared away the rock dust that carries out the gathering to elasticity sheetmetal 3 outer wall, and the dust of gathering on preventing elasticity sheetmetal 3 is too much, and then influences the damaged effect of end drill bit 26.
The specific working process is as follows:
when the profile steel supporting pile is required to be arranged in a foundation with pebbles or rocks during working, the phenomenon that the profile steel supporting pile inclines or piles are difficult to pile when the pile is inserted is caused due to the fact that the foundation with the pebbles or the rocks is hard and the bottom end of the profile steel supporting pile is flat; the supporting pile body is inserted into an area to be installed through a vibration pile driver, along with the continuous downward movement of the supporting pile body 1 under the external vibration force, when the bottom end of the supporting pile body 1 meets rocks or pebbles, because the supporting pile body 1 continuously moves downward through the vibration force, when the supporting pile body 1 is pushed downward, the supporting core 22 is pushed to move downward, the rotating core rod 23 is driven to move downward, the rotating core rod 23 which slides downward rotates is generated due to the rotary matching of the spiral groove 231 on the rotating core rod 23 and the rotating column 28, the bottom drill bit 26 can rotate and move downward, the torsional spring 27 can be generated by the downward rotating bottom drill bit 26, and the bottom drill bit is compressed downward, so that the alloy steel balls 29 arranged at the bottom end of the bottom drill bit 26 perform the punching operation on the upper surface of the rocks or pebbles, along with the continuous downward movement of the supporting pile body 1 under the external vibration force, through a plurality of drilling positioning unit 2 that set up on the stake body 1 of strutting, and then make the end drill 26 both can strike at the surface of rock and carry out the breakage, can play the effect of location again simultaneously to strutting stake body 1, prevent because the outer wall of rock or cobble is comparatively hard, lead to strutting stake body 1 and produce the skew or appear the unstable phenomenon of shaped steel fender pile installation, and then influence the safe use effect of shaped steel fender pile.
