Abstract
The utility model relates to a pedestal type duct prefabricated pile of reinforced concrete, belonging to the technical field of building operation, comprising a pile body and an expansion head. The top of the pile body is a plane, the pile head is conical, and the center of the pile body has a through hole. The enlarging head is the circular cylinder of the conical pile head, which is concentric but has different diameter. The utility model can increase the bearing capacity of a pile and can ensure the consistency of the top-mark bottoms of piles, which reduces the construction cost thereby.
Description
The utility model belongs to the constructions work technical field, further relates to a kind of expansion die bed road with holes precast reinforced concrete piles.
Its pile crown of conventional precast reinforced concrete piles that now uses is the cone angle type, owing to be subjected to the condition restriction of pile body and pile sinking equipment, in pile driving process, be difficult to enter the certain depth of dense sand stratum, and the thickness of the power of holding of great majority building, layer of sand and exposure absolute altitude great changes have taken place, though the preformed pile bearing capacity in a lot of places can meet design requirement, the high uneven waste that causes of stake top mark.
The purpose of this utility model is to provide a kind of bearing capacity that improves stake, and the expansion die bed road with holes precast reinforced concrete piles that a top mark height is reached unanimity.
The utility model comprises pile body and enlarged footing, and the pile body top is the plane, and pile crown is taper, and there is through hole at the pile body center, and enlarged footing is cylindrical for the concentric Different Diameter of parcel taper pile crown.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
The utility model pile body 3 is cylinder or square, and pile body 3 tops are the plane, and pile crown 4 is taper, and pile body 3 centers have through hole to connect to pile crown 4, and enlarged footing 5 is the cylinder of the concentric Different Diameter of parcel taper pile crown 4.
The utlity model has following advantage:
1, when stake end stratum is the limited thickness layer of sand, can improve by expanding the end Bearing capacity and uniformity, and make long being consistent of stake.
2, when stake end stratum is the thickness layer of sand, can guarantee to advance bottom the enlarged footing Enter layer of sand " critical thickness ", do diving of supporting course thereby greatly brought into play layer of sand Power increases substantially the end load.
3, when the stake end is in soil layer, guarantee that bearing capacity must do stake very long.Soil layer carries out the pile sinking expansion end as bearing stratum as long as this technology has preferably, both can improve bearing capacity, thereby reduce cost, has widened the scope of application of precast reinforced concrete pile.In addition, the soil layer shear strength is lower, and it is very poor to destroy ability to bear for thrusting of stake point, made enlarged footing after its failure mode change, bearing capacity must be improved.
