The utility model content
The utility model provides a kind of post-stressed little combination foundation structure at traditional steel concrete single pile structure above shortcomings.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of post-stressed little combination foundation structure comprises the suspended deck structure that is arranged on the soil body, pass and be fixed on a plurality of anchor poles on the described suspended deck structure, the bottom that described anchor pole is positioned at suspended deck structure is equipped with fixedly centering structure, is positioned at described suspended deck structure below and is filled with high-strength grouting or high-strength concrete near space around the anchor pole.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described is precast concrete, has a plurality of through holes in the described precast concrete, is equipped with anchor pole in the described through hole.
Further, described suspended deck structure is the cast structure that forms by cast-in-place concrete, and the described outer cover that is positioned at the anchor pole of suspended deck structure inside is provided with the PE pipe.
Further, stretch out outside the suspended deck structure on the top of described anchor pole.
Further, the described anchor pole that stretches out outside the suspended deck structure is a hollow-core construction.
Further, the cross section of described fixedly centering structure size and the anchor pole cross section size that is filled with the space of high-strength grouting or high-strength concrete all around is complementary.
Further, the threaded portion that described anchor pole is positioned at suspended deck structure top is socketed with nut, and the below of described nut is provided with pad, described anchor pole by nut and spacers on suspended deck structure.
Further, have screw thread on the described anchor pole, the screw thread on the described anchor pole is the circular arc screw thread of 360 degree continuity rotations.
Further, the described soil body is provided with the foamed glue structure, and described foamed glue structure has through hole, and described anchor pole wore the through hole of foamed glue structure.
The beneficial effects of the utility model are: post-stressed little the combination foundation structure of the utility model has the bearing capacity height, the advantage that section area is little, the construction operation face is little, minimizing destroys and vibration the face of land, needing after little combination foundation structure finished that the anchor pole in it is carried out post tensioning handles, the stressed sinking of suspended deck structure meeting, anchor pole all adopts post-tensioned prestressing, can reduce the size of suspended deck structure effectively, improve the drag of foundation structure, adopt the anchor pole profile of proprietary technology simultaneously, can effectively reduce anchorage length, improve anchored force, be applicable to the various hard soil bodys or ROCK CONDITIONS.
Description of drawings
Fig. 1 is the structural representation of post-stressed little the combination foundation structure of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 1, described post-stressed little combination foundation structure comprises the suspended deck structure 3 that is arranged on the soil body 4, pass and be fixed on a plurality of anchor poles 1 on the described suspended deck structure 3, the bottom that described anchor pole 1 is positioned at suspended deck structure 3 is equipped with fixedly centering structure 7, is positioned at described suspended deck structure 3 belows and is filled with high-strength grouting or high-strength concrete 9 near space 6 around the anchor pole 1.Described suspended deck structure 3 is a precast concrete, has a plurality of through holes in the described precast concrete, is equipped with anchor pole in the described through hole.Described suspended deck structure 3 is the cast structure that forms by cast-in-place concrete, and the described outer cover that is positioned at the anchor pole 1 of suspended deck structure 3 inside is provided with PE pipe 2, and stretch out outside the suspended deck structure 3 on the top of described anchor pole 1.The described suspended deck structure 3 outer anchor poles 1 that stretch out are hollow-core construction.The cross section size that is filled with the space 6 of high-strength grouting or high-strength concrete 9 around the cross section size of described fixedly centering structure 7 and the anchor pole 1 is complementary.The threaded portion that described anchor pole 1 is positioned at suspended deck structure top is socketed with nut 5, and the below of described nut 5 is provided with pad, described anchor pole 1 by nut 5 and spacers on suspended deck structure 3.Have screw thread on the described anchor pole 1, the screw thread on the described anchor pole 1 is the circular arc screw thread of 360 degree continuity rotations.The described soil body 4 is provided with foamed glue structure 8, and described foamed glue structure 8 has through hole, and described anchor pole 1 wore the through hole of foamed glue structure.
