Roadbed supporting pile for road and bridge building and repairing construction

Abstract

The invention provides a roadbed supporting pile for road and bridge building and repairing construction, and relates to the field of supporting piles. The roadbed supporting pile comprises a column body, a plurality of sets of isolation grooves are formed in the outer side of the column body, a plurality of sets of through grooves are formed in the outer side of the column body in a penetrating mode, a plurality of sets of drainage plates are installed on the outer side of the column body, the drainage plates are located above the through grooves, a bearing disc is installed at the bottom end of the column body, and a base is installed at the bottom end of the bearing disc. A soft soil layer can be quickly broken through the conical arrangement of the base, meanwhile, a plurality of sets of cutting blocks are installed on the outer side of the base in a matched mode, breakthrough force of the base can be increased, combination of the column body and a roadbed is assisted, the multiple sets of isolation grooves are formed in the outer side of the column body, so that the surface area of the outer side of the column body is increased, the transverse friction force between the column body and a roadbed part is increased, the column body can be kept in a vertical state after entering the roadbed, and the combination process of the supporting pile and the roadbed is effectively assisted.

Description

technical field [0001] The invention relates to the field of support piles, in particular to a roadbed support pile for road and bridge construction. Background technique [0002] Bearing piles are also called end-bearing piles. The pile tip is supported on a hard soil layer, and the load it bears is considered to be completely supported by the reaction force of the pile tip soil. It mostly appears in the covering layer with a certain thickness, and below it is For the foundation of hard soil or rock layer, when the support pile is used on a soft roadbed, if the breakthrough force in the early stage is too high, it will easily cause the support pile to sink too quickly and easily tilt. If the breakthrough force is lacking, the support pile will not be able to go deep into the foundation later. , and the stabilized support pile is cylindrical, and has a weak grip on the foundation.

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a roadbed support pile for road and bridge construction, which solves the problem that when the support pile is inserted into a softer roadbed, the breakthrough force in the early stage is too high, causing the support pile to sink too quickly and easily tilt, and The low breakthrough force in the later stage leads to the situation that the support pile cannot go deep into the foundation, and the problem that the grip of the support pile is weak after the support pile is stabilized
