Abstract
The utility model belonging to the rammer technology field for the building ground treatment engineering, in particular to a special-shaped rammer adopts a strong tamping replacement method and comprises a drum shape rammer and a hook, which has solved the problem in prior art that all kinds of the strong tamping replacement rammers coexist and has no ideal effect after consolidation. A plurality of up-down transfixed vent grooves is arranged on the lateral sides of the upper and lower platforms with height ratio 2/1. The utility model has the advantages of the better treating depth with suitable shape rammer; less construction difficulty, better treatment effect of strong tamping replacement base and the better development outlook in the market of filling-sea subsoil and soft soil foundation treatment.
Description
Technical field
The utility model belongs to the technical field of the used hammer ram of building lot treatment project, specifically is the special-shaped hammer ram that a kind of dynamic replacement method is used.
Background technology
The dynamic replacement method is to develop and next a kind of novel method for processing foundation on the Treatment by Dynamic Compaction foundation.It is the coarse granule material that adopts backfill piece stone, rubble, sand, slag, building debris and other high strength, good water permeability in tamping pit, utilize the high energy impact events and the vibration of dynamic compaction, these coarse granule material are rammed in the soil, form the ground of whole laminar displacement or the displacement of column stake formula, the method for processing foundation that this dynamic compaction combines with displacement method is the dynamic replacement method.The dynamic replacement method is the new development of ramming by force in foundation treatment technology, and this technology has enlarged the application of strong tamping technology.
The dynamic replacement method consolidated subsoil mechanism of action is similar to dynamic compaction.It is that weight with several tons or tens tons falls from eminence, and repeated multiple times is rammed ground, and ground is carried out strong compaction, and this powerful tamping energy produces strong shock wave (wherein the volume ripple plays a leading role, and comprises compressional wave and shear wave) and dynamic stress in ground.Propagate to ground depth direction from ramming the compressional wave and the shear wave that a little send, make several stages such as the compression of foundation soil experience hole, local liquefaction, variable infiltration (dynamic drainage) and actual effect thixotroping recovery.A large amount of engineering practices prove, the dynamic replacement method has consolidation effect preferably, many acting on all over the body such as its collection cushioning effect, composite soil effect, the drainage of permeable stake (pier), compacted effect, the close effect of shaking, so the reinforcing principle of dynamic replacement is equivalent to strong rammer (encryption), rubble pier, large diameter catch pit three sum, thereby reaches the purpose of effective consolidated subsoil soil.
But the selecting for use of dynamic replacement hammer ram in the Foundation Treatment, clear and definite regulation in codes and standards, and in the dynamic replacement ground treatment construction skill, selecting for use of hammer ram is a very crucial step.Whether the effect that suitable capitate is handled ground can satisfy the conclusive effect that designed.
Summary of the invention
The utility model rams the not really desirable problem of back effect in order to solve in the prior art various dynamic replacement hammer rams and to deposit, and a kind of special-shaped hammer ram is provided.
The utility model adopts following technical scheme to realize: special-shaped hammer ram comprises hammer body, suspension hook.Hammer body is a cydariform, and the side of upper and lower stage body is provided with the air channel of some up/down perforations.The aspect ratio of last stage body and following stage body is 2: 1.
The beneficial effects of the utility model: suitable capitate can better be handled the degree of depth, reduces difficulty of construction, improves dynamic replacement Measures for Making Ground and Foundation effect, and fills out Haiti base, Soft Ground extensive market in China, and bright development prospect is arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the vertical view of Fig. 1
Among the figure: the last stage body of 1-, stage body under the 2-, 3-air channel, 4-suspension hook.
The specific embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described further, present embodiment is to be used for illustrating of the present utility model, rather than the utility model is done any restriction.
The special-shaped hammer ram small in ends, broad in the middle that comes from the common hammer ram development of patty, upper and lower section ratio is about 2: 1.Do the air channel 3 of 3～4 up/down perforations all around, general upper bottom surface diameter is at 1.2～1.5m, and the mid portion diameter is at 1.3～1.8m, and the bottom surface diameter is at 1.0～1.5m, and hammer is high at 2～3m, and looking hammer ram size each several part size can change in this scope.
Claims (2)
1, a kind of special-shaped hammer ram comprises hammer body, suspension hook (4), it is characterized in that hammer body is a cydariform, and the side of stage body on it (1), following stage body (2) is provided with the air channel (3) of some up/down perforations.
2, special-shaped hammer ram according to claim 1, the aspect ratio that it is characterized in that upper and lower stage body is 2: 1.
