Abstract

The utility model discloses a high -efficient strong ram that consumes slowly, be equipped with the hammer block at the hammer end and the hammer ear that the hammer block upper end is connected including the lower extreme to reach a plurality of gas pockets that run through the hammer block perpendicularly, the lower extreme that the hammer block is by last hammer body, hammer the body into shape and the hammer is constituteed at the end down to be hammered the body on, into shape and be the cylindric top welding of hammering the body on, into shape and have a hammer ear hammered the body on, into shape is equipped with down hammers the body into shape, descend to hammer into shape to be greater than the cylinder of hammering the body into shape as the diameter, the bottom of hammering the body down into shape is equipped with the hammer end, the hammer is radius frustum shape the end, and the top diameter at the hammer end is with to hammer the body diameter into shape down unanimous hammers the body on, into shape, hammer that body, the hammer end and hammer sword are all as an organic whole to take shape into shape down, and hammers the top edge at the end into shape and hammer into shape at one's side along the parallel and level with lower, the inclined plane at the hammer end evenly is provided with the hammer sword. On hammer the body into shape, hammer the body into shape down, the hammer basal cross section centre of a circle is identical on same perpendicular line. The utility model discloses the static pressure value is big, and dark to soil body influence, energy loss is little, and the soil body vertically reaches the crowded close effect of side direction and is showing, and difficultly produces useless hammer, inhales the hammer phenomenon.

Description

A kind of efficient low-consume strong rammer hammer

Technical field

The utility model relates to basement process apparatus field, concrete a kind of efficient low-consume strong rammer hammer.

Background technology

The hammer of current dynamic compaction and heavy tamping replacement method mostly is cylinder pie or ratio of height to diameter is the cylindric of 1.0-2.0, during identical tamping energy, tradition hammer (round pie) due to floor space excessive, static pressure is low, energy is shallow to surrounding lateral transport influence depth, and the bearing capacity of foundation soil after process is low; The cylindric hammer that ratio of height to diameter is large, static pressure is high, and influence depth is darker, and energy longitudinally transmits, and receives pore-forming when hammering into shape also dark.But there are five large drawbacks during practice of construction: one, when energy longitudinally passes ripple, not compacted to the soil body (i.e. soil between the pier) side direction between tamping point; Two, it is very dark that columnar hammer receives pore-forming when hammering into shape, and greatly, the energy loss that frictional force causes is also large for whole hammer body and soil body contact surface; Three, post hammer is higher, does not generally establish pore, when therefore becoming hole depth, when gas can be caused to compress in hole rapidly, forms a negative interaction atmospheric pressure, a large amount of consumed energy; Even if establish pore, hammer body is too high also cannot obstruction in scavenging port in time; Four, post is hole depth hammer out, and the hammer body in deep hole and the soil body contact surface rammed in hole are also large, easily cause the soil body to the absorption of hammer body when practice of construction, and namely in construction, tamping machine is difficult to pull out hammer; Five, ratio of height to diameter is too high, then hammer body center of gravity is too high, and in construction, hammer body easily swings, and easily causes useless hammer, and namely hammer body into shape and tilt to land, tamping point deflects.

Utility model content

The purpose of this utility model is the shortcoming and defect in order to overcome prior art, provides static pressure large, all large to the longitudinal lateral effect of the soil body, compacted Be very effective, and not easily produces and inhale the little a kind of efficient low-consume strong rammer hammer of hammer, useless hammer, the negative loss of tamping energy.

A kind of efficient low-consume strong rammer hammer, comprises the hammer ear that hammer body that lower end is provided with the hammer end is connected with hammer body upper end, and vertically runs through some pores of hammer body; Described hammer body was made up of upper hammer body, lower hammer body and the hammer end, described upper hammer body is cylindric, the top of upper hammer body is welded with hammer ear, the lower end of upper hammer body is provided with lower hammer body, described lower hammer is greater than the cylinder of upper hammer body as diameter, the bottom of described lower hammer body is provided with the hammer end, in rounding taper type at the bottom of described hammer, the top diameter at the hammer end is consistent with lower hammer body diameter, hammering the end into shape and hammering body into shape up and down and hammer sword into shape is all integrally formed, and hammer the end top edge is concordant at one's side with lower hammer, up and down hammer into shape body and hammer into shape the basal cross section center of circle match on same vertical line; Inclined-plane at the bottom of described hammer is evenly provided with hammer sword.

Further, the cross section of described hammer sword is pointed shape.

Further, described hammer sword is 14.

The beneficial effects of the utility model are:

1. hammer the bottom area at the end into shape all less than the cross section of upper and lower hammer body, thus static pressure is larger, darker to soil body influence depth, at the bottom of the hammer of rounding taper type simultaneously and on hammer sword enhance hammer body ram long-pending can to the reinforcing of soil body side direction, i.e. the compacted effect of soil between reinforced pier;

2. lower hammer and upper hammer are all cylindric, and the diameter of lower hammer is greater than the diameter of upper hammer, therefore upper hammer body side to ram in process not with soil body contact friction, the negative frictional resistance that hammer ram produces is also less, simultaneously hammer body in rammer hole on hammer body into shape and also contact with the soil body, more difficult cause to inhale hammer phenomenon into shape; This up-small and down-big structure makes hammer body center of gravity reduce, therefore hammers body into shape and not easily swing in construction, avoids causing useless hammer phenomenon;

3. up-small and down-big structure constructability personnel trample on lower hammer or stand directly on the ground, and the obstruction in cleaning pore ensures that pore normally runs.

Detailed description of the invention

Below in conjunction with example, detailed description of the invention of the present utility model is described in further detail:

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of efficient low-consume strong rammer hammer, comprises hammer body and the hammer ear 11 in the welding of hammer body upper end, and vertically runs through symmetrically arranged two pores 12 of hammer body; Hammer body was made up of upper hammer body 21, lower hammer body 22 and the hammer end 23, and upper hammer body 21 and lower hammer body 22 are all in cylindric, and the diameter of lower hammer body 22 is greater than the diameter of hammer body 21; The bottom of lower hammer body 22 is the hammer end 23, and the hammer end 23 be rounding taper type, and the top diameter at the hammer end 23 is consistent with lower hammer body diameter, and edge is concordant at one's side with lower hammer to hammer the top at the end into shape; The inclined-plane at the hammer end 23 evenly arranges 14 hammer swords 31, and the cross section of hammer sword 31 is tip-angled shape, shaping is all integrally watered by steel with hammer sword 31 and lower hammer body 22 with upper hammer body 21 in the hammer end 23, and upper hammer body, lower hammer body, the hammer basal cross section center of circle match on same vertical line.

The above is only preferred embodiment of the present utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite not departing from the utility model know-why; some improvements and modifications can also be made; these improvements and modifications also should be considered as within protection domain of the present utility model, and concrete size to be mated with the requirement of tamping energy according to layouting in practice of construction.
