Abstract

The utility model relates to a device for ramming the foundation. The utility model provides a rammer with heavy hammer which has a good effect to ramming the foundation and low demand for the foundation soil quality. A cone rammer with heavy hammer is composed of a hammer body and a grommet. The bottom of the hammer body is in shape of the inverted cone and the upper side of the hammer body is in shape of the column. Hammer blades which radiate outward from the tip of the cone, are arranged on the surface of the bottom of the inverted cone. Hammer wings are installed symmetrically on the surface of the upper side of the column.

Description

Cone rammer with heavy hammer

The utility model belongs to the construction work ground to be handled, particularly the parts of ground compacting treatment facility.

At present the strong rammer weight on the tamping apparatus that compacting is handled to ground mostly is garden cylindricality or prismatic, thereby when compacting is handled to ground, not only handles depth as shallow, the bearing capacity of foundation soil after handling is low, and requires high to the soil property of ground.

The purpose of this utility model provide a kind of effective to ground compacting, the ground soil property is required low strong rammer weight.

The utility model is made up of hammer body and grommet, and hammer body has back taper lower end and cylindrical upper end, and grommet is installed in the top of cylindrical upper end.

Owing to the utlity model has the back taper lower end, when the utility model is risen to the certain altitude whereabouts by hoist engine, ground is gone out the hole, this can not only insert inoganic solids rubbish and continue compacting, require low to the ground soil property, and can reinforce and degree of depth compacting processing the ground side direction, improved compacting effect, thereby reached the purpose of this utility model ground.

Fig. 1 is the utility model structural representation elevation.

Fig. 2 is that A among Fig. 1 is to view.

Fig. 3 is a B-B sectional drawing among Fig. 1.

Below in conjunction with accompanying drawing the utility model is further elaborated.

The utility model is made up of hammer body 1 and grommet 2, hammer body 1 has back taper lower end 3 and cylindrical upper end 4, grommet 2 is installed in the top of cylindrical upper end 4, back taper lower end 3 can be down taper, can also be the chamfered edge taper, has on the conical surface 5 of back taper lower end 3 from boring the hammer sword 7 that point 6 is penetrated to all not care about one's appearances, the cross section of awl sword 7 is a pointed shape, cylindrical upper end 4 can be the garden cylindricality, can also be prismatic, and symmetry is furnished with the hammer wing 9 more than two on the cylinder 8 of cylindrical upper end 4.

When using, rope on the hoist engine or suspension hook are enclosed within on the grommet 3, and throw off after the utility model risen to certain altitude, the utility model is fallen from the high-altitude, the whereabouts hour hammer wing 9 keeps taper to ram counterweight balance by force, and when the contact ground, awl point 6 on the back taper lower end 3 and hammer sword 7 have been strengthened taper and rammed weight by force to the reinforcing of ground side direction, compacted depth and the hole degree of depth, inoganic solids rubbish is inserted the hole, carry out next compacting circulation.

Claims

1, weight is rammed in a kind of taper of being made up of hammer body and grommet by force, it is characterized in that described hammer body has back taper lower end and cylindrical upper end, and grommet is installed in the top of cylindrical upper end.

2, ram weight by force according to the described taper of claim 1, it is characterized in that on the conical surface of described back taper lower end, having from boring the hammer sword that point is penetrated to all not care about one's appearances; At the symmetrical hammer wing that is furnished with more than two on the cylinder of cylindrical upper end.
