Abstract
The utility model discloses a kind of concrete prefabricated damping stake, comprise precast pile, wherein: precast pile sidewall is coated with bumper and absorbing shock layer, bumper and absorbing shock layer is rubber layer, and in the pile center hole of precast pile, filled and process is moulded, and installs damper in pile crown position.The utility model utilizes the bumper and absorbing shock of rubber, and play good absorption and dispersion to the shock loading that earthquake produces, the shock resistance of stake is significantly promoted, and meanwhile, rubber layer also can play certain safety stock as lining cutting layer.
Description
Technical field
The utility model relates to precast pile technique field, particularly relates to a kind of concrete prefabricated damping stake.
Background technology
Current most of building structure all adopts based on stake, the general distortion being reduced surrounding soil under geological process by the rigidity of stake, but the stiffness difference of the soil body and stake is larger, because the discontinuous of rigidity is easy to the destruction causing stake under the effect of earthquake, glissando therefore should be adopted to make stake reduce earthquake damage.
Utility model content
Technical problem to be solved in the utility model is for the above-mentioned state of the art, and the shock loading being provided with bumper and absorbing shock layer between oil and pile, can well absorbing and disperse earthquake to produce for a kind of, protects pile body and improve the concrete prefabricated damping stake of one of the connection effect of oil and pile body.
The utility model solves the problems of the technologies described above adopted technical scheme:
A kind of concrete prefabricated damping stake, comprise precast pile, wherein: precast pile sidewall is coated with bumper and absorbing shock layer, bumper and absorbing shock layer is rubber layer, filling foamed plastics in the pile center hole of precast pile, and installs damper in pile crown position.
For optimizing technique scheme, the concrete measure taked also comprises:
Damping bed course is provided with, damping bed course bottom adhesive hard backing plate at the bottom of the stake of above-mentioned precast pile.
Above-mentioned damping bed course is rubber layer.
Above-mentioned hard backing plate is steel plate.
The thickness of above-mentioned bumper and absorbing shock layer is 15-25mm.
The thickness of above-mentioned damping bed course is 150-250mm.
Above-mentioned hard plate thickness is 10-15mm.
Above-mentioned bumper and absorbing shock layer and the material of damping bed course are wear-resisting, corrosion-resistant elastic caoutchouc.
Compared with prior art, the concrete prefabricated damping stake of one of the present utility model, elastic shock attenuation layer is provided with at the outer wall of stake and bottom, elastic shock attenuation layer preferably adopts wear-resisting, corrosion-resistant elastic caoutchouc, utilize the bumper and absorbing shock of rubber, good absorption and dispersion is played, filling foamed plastics in pile center hole to the shock loading that earthquake produces, and in pile crown position, damper is installed, pile body bumper and absorbing shock can be strengthened further.
Compared with traditional preformed pile, the utility model patent tool has the following advantages:
1. utilize the damping property of rubber, good absorption and dispersion is played to the shock loading that earthquake produces, stop the dynamic action of earthquake to produce stake and destroy
2. rubber layer as buffer layer, can produce protective effect to stake, on the other hand, also can improve the intensity of stake on the one hand.
3. the friction factor of rubber is higher than the friction factor of concrete pile body, makes the connection effect of oil and pile body of the present utility model be better than traditional preformed pile.

In embodiment, the material of bumper and absorbing shock layer 2 and damping bed course 3 is wear-resisting, corrosion-resistant elastic caoutchouc.
The utility model, by arranging the buffer layer between oil and pile, forms the buffering between oil and pile, and its material adopts rubber.Utilize the bumper and absorbing shock of rubber, good absorption and dispersion is played to the shock loading that earthquake produces.Make stake can bear the effect of earthquake, meanwhile, rubber layer also can play certain safety stock as lining cutting layer.The damper 6 that the foamed plastics 5 of filling in pile center hole and pile crown position are installed all can play absorption and dispersion to the shock loading that earthquake produces further, promotes the shock resistance of stake.
The construction method of described damping stake comprises the steps:
One, drill hole of drilling machine: adopt rig to get out building stake deep hole in precalculated position;
Two, slush pump slurry-sucking: mud is extracted out by drill hole of drilling machine;
Three, damping stake is squeezed into: adopt hammering method or static pressure method to squeeze into damping stake to design elevation.
Second embodiment:
In embodiment, the thickness of bumper and absorbing shock layer 2 is 25mm.
In embodiment, the thickness of damping bed course 3 is 250mm.
In embodiment, hard backing plate 4 thickness is 15mm.
Do not state part with the first embodiment.
Below be only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, not departing from the some improvements and modifications under the utility model principle prerequisite, protection domain of the present utility model should be considered as.
