Description
Technical field
A kind of Built-up rammer reducing positice ground effect of the utility model, belongs to building operations strong rammer equipment technical field, is specifically related to a kind of strong rammer hammer of Ground Treatment.
Background technology
Dynamic compaction is that tens tons of (being generally 8-40t) weights freely fall from tens meters of (general 6-40m) eminences by one, carries out method that is compacted, strong compaction to foundation soil.In the work progress of dynamic compaction foundation process, the strong rammer hammer major part of prior art is that cast steel casting forms, and at strong rammer hammer after dynamic compaction machinery breaks off relations, the free-falling of strong rammer hammer can form air cushion by compressed air, and must consume a part of tamping energy affects compaction effect.If the area of strong rammer hammer bottom is too small shared by non air exit hole or steam vent, air can be made not easily to discharge, in strong rammer process, easily form negative pressure of vacuum after the ram contacts soil body and inhale hammer (being similar to piston effect); Gas can produce the very high explosion formation noise pollution of decibels to discharge simultaneously; Due to piston effect, gas also can take up a large amount of soil crushings in discharge process, crushed stone flies out from steam vent, affects the safety of equipment and constructor.
The technical deficiency of existing strong rammer hammer is: only have minority steam vent due on the hammer body that the strong rammer had is hammered into shape, and the ratio of shared whole hammer ram bottom area is less, and strong rammer hammer freely falling body compressed air does negative work, affects compaction effect; Air can not be got rid of in time can form negative pressure of vacuum.The strong rammer hammer hammer end is flat, is unfavorable for the discharge of air, and compressed air forms air cushion (air column) effect obviously, affects the consolidation effect of strong rammer.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is to provide a kind of body weight-adjustable and can reduces the Built-up rammer of positice ground effect, strengthens ground stabilization effect, and not easily inhales hammer, can realize a hammer multiplex.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of Built-up rammer reducing positice ground effect, comprise top layer hammer ram body, middle hammer ram body, bottom hammer ram body and connecting bolt, a bottom hammer ram body, multiple middle hammer ram body and a top layer hammer ram body are stacked successively from top to bottom and are fastened and fixed by multiple connecting bolt and form cylinder hammer ram body, center above top layer hammer ram body is provided with hoisting ring, between described top layer hammer ram body and middle hammer ram body, between adjacent middle hammer ram body, on binding face between middle hammer ram body and bottom hammer ram body, relevant position is equipped with the projection and groove of working in coordination, described top layer hammer ram body, the opposite position of middle hammer ram body and bottom hammer ram body is equipped with exhaust hole.
Described connecting bolt is set with ground connection to ram body and ground connection and ram body and be positioned at below bottom hammer ram body, it is hemisphere that described ground connection rams body, or is cuboid, or is cone.
Described ground connection is rammed on the connecting bolt between body and bottom hammer ram body and is also set with pad.
The position that described top layer hammer ram body, middle hammer ram body are corresponding with the outer wall of bottom hammer ram body is equipped with exhaust groove.
The beneficial effect that the utility model is compared with the existing technology had is: the utility model stacks with the fixing combination of bolt by multilayer hammer ram body, this body weight of hammer ram is adjusted by the quantity of middle hammer ram body, expand the scope of application, and be convenient to transport; Hammer ram body bottom portion adds ground connection by bolt and rams body, and kiss the earth at first when making it ram, not only increases tamping depth, and multiple ground connection is rammed body and exchanged use and be applicable to multiple different function requirements, realizes a hammer multiplex; Projection between hammer ram body and groove make it play the role of positioning when mounted, and in use can play the function of anti-shearing, avoid hammer ram body relative displacement reduction of service life; The design of exhaust hole and exhaust groove makes it be discharged in time by air in hole ramming in work, reduce positice ground effect to affect the negative work of the consolidation effect of strong rammer, improve strong rammer efficiency, avoid crushed stone and soil crushing inhale hammer due to negative pressure of vacuum and fly out simultaneously, increase working security.
