Abstract
The utility model belongs to the technical field of the ram and specifically relates to a strong ram of improved generation. A strong ram of improved generation, includes the hammer block, the hammer block has cylinder steel sheet shell, has filled reinforced concrete in the shell of hammer block, set up a plurality of bleeder vents that link up from top to bottom on the hammer block, the bleeder vent is the funnel -shaped structure that young, the lower port in upper end is big, the diameter of port is 19 of hammer block diameter on the bleeder vent, and the diameter of port is 745 of hammer block diameter under the bleeder vent, the bottom surface of hammer block is circular plane, and the number of the bleeder vent of offering on the hammer block equals the hammer block floor space and uses square metre integral value as the unit. The utility model discloses optimize the bleeder vent shape of hammer block on prior art's basis, change cylinder type bleeder vent into fall infundibulate bleeder vent, have following advantage: 1, ram the difficult bleeder vent that gets into of soil, 2, even the clearance is changeed to the entering bleeder vent.
Description
Technical field
The utility model relates to hammer ram field, especially a kind of modified strong rammer hammer.
Background technology
Dynamic compaction refers to the bearing capacity into improving soft foundation, fall to ramming the method that soil layer makes the rapid consolidation of ground from certain altitude with weight, also known as dynamic consolidation method, it utilizes lifting appliance, the weight of 10 ~ 40 tons is promoted to 10 ~ 40 meters of eminences and makes its free-falling, rely on powerful tamping energy and shock wave compacting soil layer.Dynamic compaction is mainly used in sandy soil, unsaturated rockmass and Artifical Fill Ground; To unsaturated cohesive soil ground, general employing is rammed or continuously point all over the method rammed of interval, and according to requirement of engineering by field trial to determine compacting number of times and effective compacted depth.Existing experience shows: under 100 ~ 200 tons of rice compaction efforts, generally can obtain effective compacted depth of 3 ~ 6 meters.
As shown in Figure 1, strong rammer hammer of the prior art adopts cylindrical shape outer cover of steel plate, interior hot-metal carburized steel reinforced concrete, several cylindrical air-vents are set in hammer ram, aperture is 25 ~ 30cm, and it can reduce to lift by crane the suction of hammer ram, can reduce again hammer ram land before the energy loss that causes of instantaneous air cushion upper pulling force.
Then, in practice of construction process, when especially ramming cohesive soil ground, air-vent is easy to by clay injection, thus air-vent is blocked.As cleared up not in time, easily cause carry hammer difficulty and strong rammer energy loss is larger; As frequent cleaning, because hole wall is vertical, between the earth pillar of injection air-vent and ventilative hole wall, there is larger frictional force, be difficult to cleaning, take time and effort, affect programming.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of soil body not easily in injection air-vent, even if a small amount of soil body injection air-vent, and the also modified strong rammer hammer of more easy to clean.
The utility model solves the technical scheme that its technical problem adopts: a kind of modified strong rammer hammer, comprise hammer body, described hammer body has cylindrical shape outer cover of steel plate, steel concrete is perfused with in the shell of hammer body, described hammer body offers the air-vent of some up/down perforations, described air-vent is the funnel-shaped structure that upper end is young, lower port is large, and the diameter of described air-vent upper port is 1/9 of hammer body diameter, and the diameter of air-vent lower port is 7/45 of hammer body diameter; The bottom surface of hammer body is circular flat, the number of the air-vent that hammer body is offered equal hammer body floor space by square metre in units of integer value.
As preferably, described hammer body diameter is 225cm, and the diameter of air-vent upper port is 25cm, and the diameter of air-vent lower port is 35cm.
The beneficial effects of the utility model are: the utility model is optimized the air-vent shape of hammer body on the basis of existing technology, changes column type air-vent into fall infundibulate air-vent, has the following advantages:
1, ram soil and not easily enter air-vent;
Even if 2 enter air-vent, more easy to clean.

Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in figs. 34, a kind of modified strong rammer hammer, comprise hammer body 1, hammer body 1 has cylindrical shape outer cover of steel plate 2, in the shell 2 of hammer body 1, be perfused with steel concrete 3, hammer body 1 offer the air-vent 4 of some up/down perforations, air-vent 4 is the funnel-shaped structure that upper end is young, lower port is large, the diameter of air-vent 4 upper port is 1/9 of hammer body 1 diameter, and the diameter of air-vent 4 lower port is 7/45 of hammer body 1 diameter; The bottom surface of hammer body 1 is circular flat, the number of the air-vent 4 that hammer body 1 is offered equal hammer body 1 floor space by square metre in units of integer value.
In the present embodiment, be specially: hammer body 1 diameter is 225cm, the diameter of air-vent 4 upper port is 25cm, and the diameter of air-vent 4 lower port is 35cm.
As shown in Figure 5, the construction flow chart of modified strong rammer hammer, changes former cylindrical air-vent into fall infundibulate air-vent when production strong rammer is hammered into shape, be convenient to ram injection soil in process and not easily block air-vent, even if blocking, its cleaning difficulty also reduces greatly, increases work efficiency.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on manual, must determine its technical scope according to right.
