Abstract
The utility model discloses existing road and widen structure, build favour road surface domatic on, it comprises the first soil nailing bar and the second soil nailing bar; Described first soil nailing bar is provided with fixed end and free end, and fixed end is embedded into described domatic, and free end domaticly to stretch out from described; One end of described second soil nailing bar is embedded into described domatic, and the other end is fixedly connected with described free end; Angle between described second soil nailing bar and road surface is less than the angle between the first soil nailing bar and road surface, first soil nailing bar and domatic between form V-arrangement region, build backfilling material in V-arrangement region and form V-arrangement road structure, the end face of V-arrangement road structure is concordant with the surface of existing road.The utility model expands the width of existing road under the prerequisite not needing to carry out road periphery the process such as explosion, soil transport, and construction volume is little and do not affect road surrounding enviroment, constructs convenient.
Description
Technical field
The utility model relates to existing road and widens structure, is applicable to constructing road engineering field.
Background technology
Increase existing road width in correlation technique to need to carry out the process such as explosion, soil transport to road periphery, great in constructing amount and affect road surrounding enviroment.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide existing road and widens structure, great in constructing amount, the problem that affects road surrounding enviroment that solve that road in correlation technique widens.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: structure widened by existing road, build favour road surface domatic on, it comprises the first soil nailing bar and the second soil nailing bar; Described first soil nailing bar is provided with fixed end and free end, and fixed end is embedded into described domatic, and free end domaticly to stretch out from described; One end of described second soil nailing bar is embedded into described domatic, and the other end is fixedly connected with described free end; Angle between described second soil nailing bar and road surface is less than the angle between the first soil nailing bar and road surface, first soil nailing bar and domatic between form V-arrangement region, build backfilling material in V-arrangement region and form V-arrangement road structure, the end face of V-arrangement road structure is concordant with the surface of existing road.
Described first soil nailing bar is equipped with steel screen layer on the surface on road surface, and the upper surface of steel screen layer is installed with geotechnological layer of cloth.Described second soil nailing bar comprises outer tube and the interior reinforcement through outer tube, and leave space between outer tube and interior reinforcement, the ramp portion that do not embed of interior reinforcement is fastened with bearing steel plate by fastening nut.
Further, for strengthening the steadiness of structure, being provided with multiple interval between described first soil nailing bar and the second soil nailing bar and inserting domatic short wooden peg.
Further, for preventing vehicle from exceeding road boundary, the end face of described V-arrangement roadbed is provided with roadblock, and the fixed end of the contiguous first soil nailing bar of roadblock, described roadblock comprises multiple vertical rod being fixed to backfilling material.
The beneficial effects of the utility model are: on domatic, arrange the first soil nailing bar and the second soil nailing bar, first soil nailing bar and domatic between form V-arrangement region, build backfilling material in V-arrangement region and form the end face V-arrangement road structure put concordant with road surface, thus do not needing the width expanding existing road under the prerequisite of road periphery being carried out to the process such as explosion, soil transport, therefore construction volume is little and do not affect road surrounding enviroment, constructs convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 12-first soil nailing bar; 14-steel screen layer; 16-geotechnique layer of cloth; 20-free end; 22-fixed end; 28-is domatic; 30-second soil nailing bar; 34-outer tube; Reinforcement in 36-; 42-fastening nut; 40-bearing steel plate; 44-steel bar; The short wooden peg of 60-; 70-roadblock; 74-vertical rod.
Detailed description of the invention
By reference to the accompanying drawings, the utility model is described in further detail.
See Fig. 1, structure widened by the present embodiment existing road, builds on favour road surface domatic 28, comprises the first soil nailing bar 12 and the second soil nailing bar 30.
The fixed end 22 that described first soil nailing bar 12 is provided with fixed end 22 and free end 20, first soil nailing bar 12 is embedded into described domatic 28, and the free end 20 of the first soil nailing bar 12 stretches out from described domatic 28; Described first soil nailing bar 12 is equipped with steel screen layer 14 on the surface on road surface, and the upper surface of steel screen layer 14 is installed with geotechnological layer of cloth 16.
One end of described second soil nailing bar 30 is fixedly connected with the free end 20 of the first soil nailing bar 12 by steel bar 44, the other end is embedded into described domatic 28; Second soil nailing bar 30 comprises outer tube 34 and the interior reinforcement 36 through outer tube 34, leaves space between outer tube 34 and interior reinforcement 36.Angle between described second soil nailing bar 30 and road surface is less than the angle between the first soil nailing bar 12 and road surface.The part not embedding domatic 28 of described interior reinforcement 36 is fastened with bearing steel plate 40 by fastening nut 42.Further, for strengthening the steadiness of structure, between described first soil nailing bar 12 and the second soil nailing bar 30, be provided with the short wooden peg 60 that multiple interval inserts domatic 28.
Described first soil nailing bar 12 forms V-arrangement region with domatic 28, and build backfilling material in described V-arrangement region and form V-arrangement road structure, the end face of V-arrangement road structure is concordant with the surface of existing road, and the width of V-arrangement road structure is road and increases width newly.
Further, for preventing vehicle from exceeding road boundary, the end face of described V-arrangement roadbed is provided with roadblock 70, and the fixed end 22 of the contiguous first soil nailing bar 12 of roadblock 70, it comprises multiple vertical rod 74 being fixed to backfilling material 49.
