Abstract
The invention provides an adjustable deforming environmental protection device utilizing waste vehicle tires to resolve a bridgehead vehicle-jumping problem. The device is arranged between a basal bed of a bridgehead road and an earthfilling bed of the bridgehead road. The device is characterized in that the structure of the adjustable deforming environmental protection device is as follows: a plurality of layers of tires are piled up and down to form a tire column, in which a spring column is arranged and earth is filled; a plurality of tire columns provided with spring columns are arranged side by side, and the upper part and the lower part of each row of tire columns are provided with a wooden sleeper with a pull bar respectively, and both ends of the upper and the lower wooden sleepers are fixedly connected with tire columns and spring columns by stay bolts and movable nuts in a precompressed mode respectively; the adjustable deforming environmental protection device adopting the optimized proposal has the outside provided with a protective sleeve. The device has the advantages of simple process, easy manufacturing, convenient construction, low cost, convenient and accurate control and easy popularization; moreover, the device can resolve the bridgehead vehicle-jumping problem, can also be used as light materials to fill road embankments for the reutilization of waste tires and avoid the black pollution.
Description
Technical field
The present invention relates to utilize in a kind of speedway and the road and bridge engineering waste tire of automobile to solve the adjustable deformation and environmental protection device of problem of bumping at bridge-head, and can effectively carry out the junked tire recycling treatment.
Background technology
So-called " end of the bridge " generally is meant the joining place of bridge or access bridge and road, and vehicle ' often occurs jolting, beating to the end of the bridge place, promptly so-called problem of bumping at bridge-head.This phenomenon generally is because the relative settlement of bridge road and end of the bridge road causes.At present, the way that solves bumping at bridge-head generally is that the end of the bridge soft foundation is carried out consolidation process, perhaps adopts the lightweight fill of banketing, and transition slab at bridge head perhaps is set, and perhaps manually reduces bridge floor and changes so that adapt to end of the bridge road surface settlement after construction.But, the relative settlement of bridge road and end of the bridge road still exists, and can be along with the prolongation of service time, the sedimentation of end of the bridge soft foundation still can be greater than the sedimentation of bridge ground, it is uneven that the sedimentation difference continues to make both road surfaces to produce, so these measures of prior art still can not solve the end of the bridge relative settlement that the soft foundation rheology causes effectively.
Summary of the invention
Deficiency for the method that overcomes existing solution problem of bumping at bridge-head, the invention provides a kind of environmental protecting device that utilizes waste tire of automobile to solve the adjustable deformation of problem of bumping at bridge-head, not only can prevent and treat bumping at bridge-head, and can be used as the light material railway embankment using, effectively solve present black pollution problem, promptly carry out the recycling treatment of junked tire.
The technical solution adopted for the present invention to solve the technical problems is, a kind of adjustable deformation and environmental protection device that utilizes waste tire of automobile to solve problem of bumping at bridge-head, be arranged between the fill subgrade of the basic unit of end of the bridge road and end of the bridge road, it is characterized in that, this adjustable deformation and environmental protection device structure is as follows, the several layers tire stacks up and down and constitutes the tire post, in the middle of this tire post, be provided with spring stack and filling soil, several tire posts that are provided with spring stack are arranged side by side, about the formation of every row's tire post, respectively be provided with the sleeper of a band pull bar, on this, the two ends of following two sleepers are connected with traveling nut with the stay bolt post respectively; Simultaneously, described " the sleeper two ends are connected with traveling nut with the stay bolt post " employing is fixed tire post and the precompressed mode of spring stack.
When this device is provided with, can make the bridge road concordant, can not jump the car phenomenon with the road surface of end of the bridge road; Produce not at ordinary times when the relative settlement of bridge road and end of the bridge road causes the road surface of bridge road and end of the bridge road, can adjust the stay bolt post and the traveling nut at sleeper two ends, discharge the pre compressed magnitude of tire post and spring stack, make the road surface recovery concordant.
In the prioritization scheme of the present invention, described adjustable deformation and environmental protection device outside can be provided with protective sleeve.
Described protective sleeve adopts concrete slab to make.
Applying prestressing force before adjustable deformation and environmental protection device of the present invention is installed tightens up waste tire of automobile and spring pressurized.When end of the bridge soft foundation generation rheology, the end of the bridge road can sink with the secondary consolidation settlement of soft foundation, the environmental protecting device of adjustable deformation changes the force mode that is subjected to of end of the bridge soft foundation, elongation strain with the stress relaxation correspondence of waste tire of automobile and spring compensates the secondary consolidation settlement that the soft foundation rheology causes, thereby keep the end of the bridge surface course at its top and basic unit can not sink with the sedimentation of soft foundation, guarantee the continuity and the harmony of the stressed of end of the bridge road structure layer and distortion simultaneously, thereby reach the generation that prevents the end of the bridge relative settlement, effectively prevent and treat the purpose of problem of bumping at bridge-head.
The invention has the beneficial effects as follows, the present invention is reasonable in design, technology is simple, be easy to processing, easy construction, cost are low, be convenient to accurate regulation and control, be easy to promote, can in the control problem of bumping at bridge-head, carry out the recycling of junked tire, the control black pollution.
