[0025] The present application will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0026] Example 1

[0027] Reference Figs. 1-3 As shown, a recyclable prefabricated foundation comprises a first prefabricated block 1 and a second prefabricated block 2.

[0028] A plurality of slots 3 are arranged on the splicing side of the first prefabricated block 1, and a plurality of plugs 4 are arranged on the splicing side of the second prefabricated block 2. The slots 3 and the plugs 4 are matched and spliced to realize the assembly between the first prefabricated block 1 and the second prefabricated block 2. The interlocking between the prefabricated blocks is realized through the tongue-and-groove formed by the slots 3 and the plugs 4, and the area of the contact connection is also increased.

[0029] The first prefabricated block 1 and the second prefabricated block 2 are both reinforced concrete structures in the shape of a cuboid, and the slots 3 and the plugs 4 are matching cuboid structures. The cuboid shape facilitates the processing and manufacturing of the prefabricated blocks.

[0030] The first prefabricated block 1 and the second prefabricated block 2 are both provided with drainage grooves 5, which are located on the smooth surface (upper surface) of the prefabricated blocks. The drainage grooves 5 are used for draining accumulated water to avoid the accumulation of rainwater on the foundation.

[0031] The drainage grooves 5 are provided with smooth surface pull rings 6 that can be turned over. The smooth surface pull rings 6 facilitate the hoisting of the prefabricated blocks. The turning connection can realize the switching between the two states of the pull ring standing up and lying down. When hoisting, the pull ring can be straightened up. When setting up the support foundation, the pull ring can be laid down to avoid blocking the setting up of the support. When laid down, the pull ring is tightly attached to the bottom surface of the drainage groove.

[0032] The first prefabricated block 1 and the second prefabricated block 2 are both provided with four smooth surface pull rings 6 located at the four corners, so that the prefabricated blocks are hoisted from the four corners to ensure stable hoisting.

[0033] The drainage grooves 5 are in the shape of an inverted T, and the smooth surface pull rings 6 are in the shape of an Ω. The horizontal segments on both sides of the smooth surface pull rings 6 are arranged on the flange segments on both sides of the bottom of the drainage grooves 5 to realize the clamping of the smooth surface pull rings 6 in the drainage grooves 5. When the smooth surface pull rings 6 are lifted, the blocks can be lifted synchronously. In addition, by sliding or turning over the horizontal segments in the flange segments, the position adjustment and state switching of the smooth surface pull rings 6 can be realized.

[0034] The groove of the drainage groove 5 is provided with a plate groove 7, and the plate groove 7 is provided with a detachable support plate 8. The support plate 8 is used to shield the drainage groove 5, so as to avoid the support legs of the scaffold to be suspended above the drainage groove 5 when the scaffold is erected, and to ensure the stability of the entire scaffold. The support plate 8 is provided with a plurality of drainage holes 9, so as to realize the rainwater downflow.

[0035] If the support is just erected at the position of the drainage groove, the pull ring is placed flat, and a steel plate is inserted into the notch position of the drainage groove. The width and length of the steel plate are basically the same as the total width and length of the notches on both sides of the drainage groove, and the top surface of the inserted steel plate is flush with the top surface of the precast foundation block as much as possible.

[0036] The plate grooves 7 at the groove of the drainage groove 5 are oppositely arranged, the distance between the groove bottoms of the two opposite plate grooves 7 is greater than the plate width of the support plate 8, and the width of the support plate 8 is greater than the width of the groove at the drainage groove 5, so as to realize the flexible disassembly of the support plate 8 at the groove.

[0037] The support plate 8 is provided with a plurality of latches 11 which are inserted into the drainage holes 9 of the support plate 8. The latches 11 are used to limit the left and right sliding of the support plate 8, so as to avoid the support plate 8 from being pulled out of the plate groove 7, and to ensure the stable arrangement of the support plate 8.

[0038] When the support plate 8 is disassembled, the smooth pull ring 6 is turned out of the drainage groove 5 for hoisting. When the support plate 8 is arranged, the bottoms of the two smooth pull rings 6 are connected by the iron wire 10, the tops of the two smooth pull rings 6 are respectively inclined to both ends and connected with the support plate 8 by the iron wire 10, so that the two smooth pull rings 6 form an inverted triangular support structure which can support the plate body below the support plate 8, thereby improving the support strength of the support plate 8.

[0039] Example 2

[0040] Reference Figs. 1-3 As shown in the drawings, a viaduct bent cap construction structure comprises a bridge bent cap and a roadbed structure layer at the side of the bridge bent cap. The lower part of the bridge bent cap is connected with a bridge pile foundation. The roadbed structure layer is provided with a foundation sand cushion layer. The foundation sand cushion layer is provided with a prefabricated foundation layer. The upper surface of the prefabricated foundation layer is flush with the upper surface of the bridge bent cap. The prefabricated foundation layer and the bridge bent cap are provided with a full-frame support. The prefabricated foundation layer comprises the recyclable prefabricated foundation of example 1. The prefabricated foundation layer is composed of a plurality of first prefabricated blocks 1 and second prefabricated blocks 2 which are connected with each other.

[0041] The foregoing basic examples and each further selected example of the present application can be freely combined to form a plurality of embodiments, all of which are embodiments that can be adopted and claimed by the present application. In the present application scheme, each selected example can be arbitrarily combined with any basic example and selected example.
