A plurality of through circular grooves A6 matched with the foundation piles 3 in an one-to-one correspondence mode are uniformly distributed in the square prefabricated bearing platforms 5, and four sleeve-shaped embedded parts B19 which are uniformly distributed in the circumferential direction and are welded to steel reinforcement cages in the prefabricated bearing platforms 5 are poured on the inner wall of each circular groove A6. The sliding blocks 21 are arranged in the embedded parts B19 in a sliding mode in the radial directions of the circular grooves A6, and the springs B23 for resetting the corresponding sliding blocks 21 are arranged in the embedded parts B19.

As shown in FIGS. 4, 16 and 17, three connecting grooves 8 which are horizontally distributed at intervals are formed in each of the two side walls of the prefabricated bearing platforms 5 in the bearing platform mechanisms 4. Three embedded parts All which are vertically distributed and welded to the steel reinforcement cages in the prefabricated bearing platforms 5 are poured on the inner wall of each connecting groove 8, and the upper end face of each embedded part is 9

H113P1LU 02.05.2022 provided with an inserting groove 12 allowing the connecting columns 10 which are HU102999 horizontally located on the side wall of the adjacent prefabricated bearing platform 5 and welded to the steel reinforcement cage in the corresponding prefabricated bearing platform 5 to vertically fall into. Each limiting block 15 for locking the corresponding connecting column 10 in the corresponding inserting groove 12 is horizontally arranged in the corresponding sliding groove A13 in the inner wall of each inserting groove 12 in a sliding mode, and the exposed end of each limiting block 15 is provided with an inclined face A16 allowing the corresponding connecting column 10 to enter the corresponding inserting groove 12. The springs A18 for resetting the corresponding limiting blocks 15 are arranged in the inserting grooves 12.

As shown in FIGS. 1 to 8, two guide blocks A17 are symmetrically mounted on the limiting blocks 15, and the two guide blocks A17 slide in two guide grooves A14 in the inner walls of the corresponding sliding grooves A13 respectively. The guide blocks A17 and the guide grooves A14 are matched to exert a positioning guide effect on the sliding of the limiting blocks 15 in the sliding grooves A13, and meanwhile, the springs A18 are always in a compressed state. The springs B23 for returning the corresponding sliding blocks 21 are arranged in the embedded parts B19, two guide blocks B22 are symmetrically mounted on each sliding block 21, and the two guide blocks B22 slide in two guide grooves B20 in the inner walls of the corresponding | embedded parts B19 respectively. The guide blocks B22 and the guide grooves B20 are matched to exert a positioning guide effect on the sliding of the slide blocks 21 in the corresponding embedded parts B19, and meanwhile, the springs B23 are always in the compressed state.

H113PILU 02.05.2022 blocks C59 slide in two guide grooves C53 in the inner walls of the corresponding 10108588 sliding grooves B52 respectively. The guide blocks C59 and the guide grooves C53 are matched to play a positioning and guiding role on sliding of the clamping blocks 57 in the sliding grooves B52, and meanwhile, the springs C60 are always in the compressed state.

The working process of the present invention is that in the initial state, the sliding blocks 21 in the bearing platform mechanisms 4 protrude out of the inner walls of the corresponding circular grooves A6, scraping ends of two scraping blocks 35 in the positioning grooving mechanism 24 swing out of the corresponding annular grooves 26 and abut against corresponding swing limiting columns 61, and the ends of the inclined faces D58 of the four clamping blocks 57 in the fixed connecting mechanism 49 protrude out of the inner walls of the supporting sleeves 50.

When constructing the foundation bearing platform, the foundation piles 3 with the same spacing density are inserted into the foundation 1 according to the spacing of the circular grooves A6 in the bearing platform mechanisms 4. After the upper ends of all the foundation piles 3 are cut at the same height through an existing tool, all the bearing platform mechanisms 4 are sequentially and vertically laid on the foundation 1 where the foundation piles 3 are inserted from top to bottom, and the foundation piles 3 are contained in the middles of all the circular grooves A6 in the bearing platform mechanisms 4. The side with the connecting columns 10 on the bearing platform mechanism 4 that is placed on the foundation 1 later is matched with the side with the connecting grooves 8 in bearing mechanism 4 that is placed on the foundation 1 earlier and is adjacent to the bearing platform mechanism 4 placed on the foundation 1 later, the horizontal connecting columns 10 on the bearing platform mechanism 4 that is placed on the foundation 1 later are inserted into the inserting grooves 12 in the corresponding embedded parts A11 in the corresponding connecting grooves 8 in the adjacent bearing platform mechanism 4 from top to bottom, and thus the two adjacent bearing platform mechanisms 4 are integrally connected.

In the process that the connecting columns 10 fall into the bottoms of the inserting grooves 12 in corresponding embedded parts All, when the connecting 11

H113P1LU 02.05.2022 columns 10 meet the inclined faces A16 of the limiting blocks 15 on the side walls of 10108588 the inserting grooves 12, the limiting blocks 15 contract into the corresponding sliding grooves A13 under the low pressure of the connecting columns 10, and the springs A18 for resetting the limiting blocks 15 are further compressed. When the connecting columns 10 just reach the bottoms of the inserting grooves 12 of the corresponding embedded parts A11, the connecting columns 10 just cross the limiting blocks 15, and the limiting blocks 15 reset instantly under the resetting action of the springs A18 and fix the connecting columns 10 to the bottoms of the inserting grooves 12 in the embedded parts All in an abutting-against mode. All the connecting columns 10 on one side of each bearing platform mechanism 4 are synchronously inserted into the bottoms of the inserting grooves 12 in the corresponding embedded parts A11 on the adjacent bearing platform mechanism 4, and after each bearing platform mechanism 4 is laid on the foundation 1 at a time and any two adjacent bearing platform mechanisms 4 are connected at the same time, the annular grooves 26 are sequentially cut in the side walls of the upper ends of all foundation piles 3 through the positioning grooving mechanism 24.

Each foundation pile 3 is provided with the fixed connecting mechanism 49, and the foundation piles 3 and the bearing platform mechanisms 4 are integrally connected through the fixed connecting mechanism. The installation process of the fixed connecting mechanism 49 comprises the following steps: the supporting sleeves 50 are sleeved towards the upper ends of the foundation piles 3, in the process that the supporting sleeves 50 are sleeved towards the foundation piles 3, the inclined faces D58 of four clamping blocks 57 interact with the upper ends of the foundation piles 3, the four clamping blocks 57 are rapidly contracted into corresponding sliding grooves B52 under the interaction of the upper ends of the foundation piles 3 and the inclined faces D58, and the springs C60 for resetting the clamping blocks 57 are further compressed.

When the clamping blocks 57 cross the upper end faces of the foundation piles 3, the clamping blocks 57 abut against the side walls of the foundation piles 3. In the process that the supporting sleeves 50 are sleeved on the foundation piles 3, the 12

HI13PILU 02.05.2022 horizontal positions of two clamping sleeves 55 on the outer sides of the supporting HU102939 sleeves 50 are adjusted according to the offset distance between the central axes of the foundation piles 3 and the central axes of the circular grooves A6, so that the four clamping sleeves 55 are opposite to four sliding blocks 21 on the inner walls of the circular grooves A6 correspondingly.

When the clamping sleeves 55 are about to meet the corresponding sliding blocks 21, the sliding blocks 21 are manually pressed into corresponding embedded parts B19, and the springs B23 for resetting the sliding blocks 21 are further compressed.

When the four clamping blocks 57 just meet the annular grooves 26 in the side walls of the foundation piles 3, the clamping blocks 57 are instantly pressed into the annular grooves 26 under the reset action of the corresponding springs C60, at the moment, the clamping sleeves 55 just meet the corresponding sliding blocks 21 in the axial direction and are just opposite to the sliding blocks 21, the abutting force on the sliding blocks 21 is removed, the sliding blocks 21 are instantly inserted into the corresponding clamping sleeves 55 under the reset action of the corresponding springs B23, and therefore positioning of the positioning connecting mechanisms in the circular grooves A6 is completed, and integrated connection of the foundation piles 3 and the bearing platform mechanisms 4 is completed; and then concrete is poured into all circular grooves A6 and all connecting grooves 8 in the bearing platform mechanisms 4, finally the integrated pouring of the foundation piles 3, the fixed connecting mechanism 49 and the bearing platform mechanisms 4 is completed, therefore the bearing platform mechanisms 4 and the foundation piles 3 which are spliced with each other are integrally fixed, and as a result, the prefabricated construction of the foundation bearing platform is completed. 13 ———_—_—_ —
