Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Examples

As shown in fig. 1-6, a combined prefabricated and cast-in-place piled raft foundation comprises: and (4) prefabricating a raft plate and pipe piles.

Referring to fig. 1 and 2, the prefabricated raft is formed by splicing a first prefabricated plate 1 and a second prefabricated plate 2, wherein a lower wing plate 1-1 is arranged on the first prefabricated plate 1 along the periphery, a first L-shaped clamping groove is formed between the side end of the first prefabricated plate 1 and the upper end of the lower wing plate 1-1, a plurality of bolt grooves 1-2 are uniformly distributed on the lower wing plate 1-1, the distance between the bolt grooves 1-2 and the plate edge is 20cm, and pipe pile holes 1-3 are formed in the first prefabricated plate 1; an upper wing plate 2-1 is arranged along the periphery of a second prefabricated plate 2, a second L-shaped clamping groove is formed at the side end of the second prefabricated plate 2 and the lower end of the upper wing plate 2-1, a plurality of bolt holes 2-2 are uniformly distributed on the upper wing plate 2-1, the bolt holes 2-2 are 20cm away from the plate edge, referring to fig. 4, after the first L-shaped clamping groove and the second L-shaped clamping groove are clamped and spliced, a bolt 3 extends into the bolt groove 1-2 from the bolt hole 2-2 on the upper side and is fastened through a nut, and in addition, a rubber water stop belt 4 is arranged at the splicing position of the first L-shaped clamping groove and the second L-shaped clamping groove.

Referring to fig. 3, the pipe pile is a PHC pipe pile 5, the end of the PHC pipe pile 5 is provided with a plurality of screw holes 5-1, referring to fig. 5 and 6, screws 5-2 pass through the screw holes 5-1 from the inside of the PHC pipe pile 5 to extend to the outside of the PHC pipe pile 5 and are fastened by nuts, and after the end of the PHC pipe pile 5 is placed in the pipe pile holes 1-3, the PHC pipe pile 5 is fixedly connected with the first precast slab 1 by cast-in-place concrete 6. The bolt 5-2 is 20cm longer than the diameter of the PHC tubular pile 5, so that the screw rod 5-2 after the screw cap is screwed down has enough length to be exposed outside the PHC tubular pile 5 to serve as a stressed steel bar of the cast-in-place concrete 6.

The present embodiment adopts the mode that prefabrication and cast-in-place combined together, has simplified the construction process of piled raft foundation, has reduced required manpower, material resources and the engineering time of construction.

The above is only the embodiment of the present invention, not the limitation of the patent scope of the present invention, all the equivalent structures made by the contents of the specification and the drawings are directly or indirectly applied to other related technical fields, all the same principle is within the patent protection scope of the present invention.
