Abstract
The utility model provides a compound pile core for civil engineering, and belongs to the technical field of civil engineering. The compound pile core solves the problems that according to an existing compound pile, a straight-wall precast reinforced concrete pile core is inserted into a cement-mixed pile, and the combination effect of the precast reinforced concrete pile core and the cement-mixed pile is not good. The compound pile core comprises a plurality of reinforced concrete sub piles, a plurality of pile roots are arranged between every two adjacent reinforced concrete sub piles, and the pile roots are perpendicular to the reinforced concrete sub piles. The compound pile core is used for manufacturing a compound pile.
Description
Technical field
The utility model belongs to technical field of civil engineering, is specifically related to a kind of civil engineering compound pile core.
Background technology
Compound pile is a kind of effective form of current treatment of soft foundation, to insert in cement mixing pile with prefabricated reinforced concrete pile core, rely on the chucking power of cement mixing pile to make precast reinforced concrete pile core more firm, the compound pile of application is all to insert in cement mixing pile with the precast reinforced concrete pile core of straight wall at present, easily cause the solidifying soil stake of a prefabricated mixed reinforcing bar core to be combined effect with cement mixing pile bad, affect bulk strength.
Summary of the invention
The purpose of this utility model is that the compound pile in order to solve current application is all to insert in cement mixing pile with the precast reinforced concrete pile core of straight wall, easily cause precast reinforced concrete pile core to be combined the bad problem of effect with cement mixing pile, a kind of civil engineering compound pile core is provided, and its technical scheme is as follows:
A kind of civil engineering compound pile core, it comprises the stake of more piece steel concrete, between every adjacent two joint steel concrete stakes, is provided with multiple roots, stake root and the vertical setting of steel concrete stake.
The beneficial effects of the utility model are: stake root makes a core and the better combination of cement mixing pile, increases bulk strength.
brief description of the drawings:
Fig. 1 is the new structural representation of this practicality;
Fig. 2 is that the utility model inserts the structural representation before cement mixing pile;
Fig. 3 is the stake root place enlarged diagram of Fig. 2;
Fig. 4 is the gag lever post place enlarged diagram of Fig. 3.
detailed description of the invention:
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of civil engineering compound pile core, it comprises more piece steel concrete stake 1, between every adjacent two joint steel concrete stakes 1, is provided with multiple roots 2, stake root 2 and steel concrete stake 1 vertical setting.
Described stake root 2 is rotationally connected and forms in hinge mode by two curved plates; The lower end of the steel concrete stake 1 above being positioned in two adjacent joint steel concrete stakes 1 is provided with supporting plate 1-1, supporting plate 1-1 is fixedly connected with this steel concrete stake 1, reinforcing cage 1-2 welding in the upper surface of supporting plate 1-1 and this steel concrete stake 1, is also provided with reinforcing cage 1-2 at the soffit of supporting plate 1-1; The upper end of the steel concrete stake 1 below being positioned in two adjacent joint steel concrete stakes 1 is provided with stirrup 1-3, the lower semisection of stirrup 1-3 is fixedly connected with the upper end of this steel concrete stake 1, the reinforcing cage 1-2 welding in the lower semisection inwall of stirrup 1-3 and this steel concrete stake 1; Upper end and the supporting plate 1-1 of stake root 2 are rotationally connected, and lower end and the stirrup 1-3 of stake root 2 are rotationally connected, and are provided with gag lever post 1-4 in the lower end inner side of stake root 2, and give prominence to laterally at restriction stake root 2 middle parts, and the inward at both ends side of stake root 2 folds when ensureing to drive piles.
Construction method and principle: use vibro-pile driver that this kind of civil engineering compound pile core is slowly sunk in the cement mixing pile before solidifying, cement mixing pile will be made with wet method, to ensure that this kind of civil engineering compound pile core does not shake under folded state and sinks in the mud of cement mixing pile at stake root 2, before submerging the mud of cement mixing pile, every joint stirrup 1-3 fills it up with concrete in the upper end of this stirrup 1-3, in the time that this kind of civil engineering sinks to cement mixing pile bottom with compound pile core, stake root 2 just can fold vertical with the stake 1 of steel concrete completely, the reinforcing cage 1-2 that supporting plate 1-1 soffit arranges inserts in the concrete in stirrup 1-3 upper end, fixedly be connected as a single entity Deng curing rear more piece steel concrete stake 1.
