Pavement channel flexible isolation pile

Abstract

The invention discloses a road passageway flexible isolation pile. According to the scheme, through the design of a floating structure of the isolation pile, a lengthened expansion bolt assembly is put in a ground deep hole and sleeved with a spring, a thickened bolt gasket in the lengthened expansion bolt assembly compacts and tightens a spring body at the spring ground end under the effect of torque of a lengthened sleeve spanner, a bolt of the lengthened expansion bolt assembly is tightened in the ground deep hole, the spring is sleeved with a sleeve, and tightening is carried out. Due to the basic performance that the elastic material stores energy, deforms under the effect of external force and can return to the original shape, through the reasonable design, the isolation pile can be located in a flexible (floating) working position with a large inclination angle within the ground horizontal 360-degree range, and can restore to an original vertical working position under most traffic conditions of vehicle collisions and scratches, the service life of a facility can be greatly prolonged, and meanwhile damage to people and vehicles participating in traffic is well relieved or avoided.

Description

technical field [0001] The invention specifically relates to a flexible isolation pile for road passages, and belongs to the technical field of road traffic facilities. Background technique [0002] Road passage isolation piles are road isolation facilities scientifically set up by relevant departments according to the actual needs of road flow, and their functions are to guide traffic and prevent random parking of motor vehicles. The existing isolation pile products basically have two designs: one is the steel pipe (round pipe or square pipe) material used for the isolation pile body and the welded base, which is fixed to the ground by 4 expansion bolts. Since the pile body is in a rigid working state, After being impacted and scratched by external forces such as motor vehicles, they are easily damaged and cannot be restored to their original shape by themselves. The damage rate is high, and it is easy to cause injury to personnel or vehicles; The structure of the steel pi...

Problems solved by technology

The existing isolation pile products basically have two designs: one is the steel pipe (round pipe or square pipe) material used for the isolation pile body and the welded base, which is fixed to the ground by 4 expansion bolts. Since the pile body is in a rigid working state, After being impacted and scratched by external forces such as motor vehicles, they are easily damaged and cannot be restored to their original shape by themselves. The damage rate is high, and it is easy to cause injury to personnel or vehicles; The structure of the steel pipe has been improved, and it can be tilted about 15 degrees in the other direction without damage and can be restored to its original shape. However, when it is tilted more than 15 degrees due to collision and pipe friction, inelastic deformation occurs, that is, plastic deformation (bending). Then restore the original shape and cause damage. Secondly, the aging of the plastic is accelerated under the condition of outdoor exposure, and the service life is short
