Description

Compaction device is backfilled to three backs suitable for narrow topography

Technical Field

The application relates to the field of compaction devices, in particular to a three-back backfill compaction device suitable for narrow terrains.

Background

When the pavement, the street, the building, the ditch and the bridge are built, the engineering foundation, the curb and the asphalt pavement are usually tamped. Among them, impact rollers are generally used for compaction work for large-area high fill compaction work such as highways, grade roads, airports, and dams, and high-speed hydraulic compactors and hand-held compactors are generally used for compaction work for areas such as bridges, small structures, and abutment structure backs.

To the correlation technique among the above-mentioned, in narrow passageway formula region, need carry out the road surface tamp real-time to retaining wall back of the wall, abutment back of the wall or culvert wall back of the wall, large-scale hydraulic type rammer compactor can't get into the tamping region, and stability is not enough in the tamping process of miniature traditional hand-held type rammer compactor, if constructor control shakiness, then the rammer body collides with the wall body easily, causes the harm to the wall body.

SUMMERY OF THE UTILITY MODEL

In order to can use small-size rammer compactor to tamp the road surface in narrow passageway formula area, and reduce the probability that the bottom plate harmed the wall body among the tamping process, this application provides a three back of body backfill compaction devices suitable for narrow topography.

Optionally, the bottom plate is a circular plate.

Through adopting above-mentioned technical scheme, the bottom plate of circular face moves when being close to wall position department, and the wall is tangent in the bottom plate face, and the design of circular bottom plate is favorable to the bottom plate more to laminate in the wall root position department of crooked wall, and to straight wall simultaneously, when the bottom plate approached to the wall, the area that probably touches the wall was littleer, also more does benefit to the protection wall.

Optionally, the method includes:

the rotating rod is arranged perpendicular to the ground and is rotatably connected to the machine body;

the directional wheel is connected to one end, close to the ground, of the rotating rod in a rotating mode, and when the machine body moves forwards, the directional wheel is abutted to the ground.

Through adopting above-mentioned technical scheme, in the real time that needs remove the organism in order to carry out the rammer to the ground of different positions, the user controls the dwang and makes the directive wheel rotate, and then promotes the organism and marchs. The design of directional wheel and dwang for the user can freely control the direction of roll of directional wheel, and then the advancing direction of main control organism certainly.

Optionally, the directional wheel is provided with a brake valve.

Through adopting above-mentioned technical scheme, at the organism ramming earth in-process, use the brake valve card to die the directional wheel, prevent that directional wheel from rocking at will at the organism ramming earth in-process, and then reduce the stability of ramming earth in-process organism, promote the control effect of user to organism in the operation process.
