Abstract
The utility model provides a supporting structure of be used for pavement to widen transformation, includes existing slope and sets up the existing pavement on existing slope, its characterized in that: bearing structure supports stake, many straining beams, polylith side walk slab, many concrete sleeper beams by many and mats formation the layer and forms, the utility model discloses an useful technological effect is: can be used for the transformation of widening on existing pavement, the engineering degree of difficulty is low, and area is few, and construction convenience destroys lessly to peripheral facility.
Description
Technical field
This utility model relates to a kind of footpath Widening Technique, particularly relates to a kind of supporting construction for footpath widening and improving.
Background technology
Along with the development in city, urban population increases the most day by day, and the burden of urban transportation facility is the heaviest, one of them more significant problem is exactly that due to design-build relatively early, road width is narrower for many old footpath, its traffic capacity is the most delayed, it would be highly desirable to widening and improving；Prior art is when carrying out widening and improving to old footpath, and the typically outside at existing roadbed side slope arranges new side slope to form new roadbed, then structure of sidewalk of mating formation on new roadbed, thus realizes widening existing footpath.
Aforesaid prior art is used to carry out footpath when widening, there are the following problems: 1) owing to needs arrange new side slope in the outside of existing roadbed side slope, needing to carry out backfilling to be formed new roadbed with the substantial amounts of cubic metre of earth and stone, meanwhile, to newly filling out roadbed, to carry out the difficulty of compacting operation the biggest；2) settlement difference easily occurs between new-old concrete bond, cause the footpath after widening and improving that crack occurs, there is potential safety hazard；3) prior art newly sets roadbed due to needs, and floor space is relatively big, and at present, each metropolitan urban land is the most nervous, and the application causing prior art is the most limited.
Utility model content
For the problem in background technology, the utility model proposes a kind of supporting construction for footpath widening and improving, including existing roadbed side slope and the existing footpath being arranged on existing roadbed side slope, it is improved by: described supporting construction is made up of a plurality of supporting stake, a plurality of straining beam, polylith side walk slab, a plurality of concrete sleeper beam and pave-load layer；
It is provided with mounting groove on described existing roadbed side slope, mounting groove is positioned at the outer side edges edge of existing footpath, the trend of mounting groove is mated with the trend of existing footpath, and described sleeper beam is arranged in mounting groove, and the outside of sleeper beam upper surface is provided with the step surface mated with side walk slab；Described supporting stake is arranged at the outside of existing roadbed side slope, and a plurality of supporting stake moves towards single-row layout along existing footpath, and the upper surface of supporting stake is provided with groove；The two ends of described straining beam are respectively arranged in the groove on adjacent two supporting stakes, and the upper surface of straining beam flushes with the upper surface of supporting stake；The outer end of described side walk slab is arranged on the upper surface of supporting stake, and straining beam is covered by side walk slab, and the inner of side walk slab is arranged on described step surface, and the upper surface of side walk slab flushes with the bed course of existing footpath；Described pave-load layer covers on side walk slab upper surface, and the upper surface of pave-load layer flushes with the upper surface of existing footpath.
After using this utility model, need not arrange new side slope, floor space is less, widely applicable, and this utility model directly utilizes existing roadbed side slope and supporting stake to build side walk slab, engineering excavation amount and backfill amount are the least, and are not related to Subgrade Compaction problem.
Preferably, described side walk slab and straining beam all use concrete cast in situs, and the reinforcing bar in straining beam stretches in side walk slab.
Preferably, between described side walk slab and described bed course, it is provided with flexible gap, in flexible gap, is filled with Colophonium loose hemp fiber.
Preferably, the outer side edges of described side walk slab upper surface, along being provided with guardrail, is connected by dowel between guardrail lower end and side walk slab.
Advantageous Effects of the present utility model is: can be used for the widening and improving of existing footpath, engineering difficulty is low, and floor space is few, easy construction, destroys less to peripheral facility.
Accompanying drawing explanation
Fig. 1, structure section schematic diagram of the present utility model；
In figure, the title corresponding to each labelling is respectively as follows: supporting stake 1, straining beam 2, side walk slab 3, concrete sleeper beam 4, pave-load layer 5, existing roadbed side slope 6, bed course 7, guardrail 8.
