[0031] like Figure 1-Figure 6 As shown, a rear anchor connection device for a precast concrete waist beam of a deep foundation pit, during the installation process, the connection component 3 can be plugged into the plug-in component 4, and when it needs to be disassembled, the connection component 3 can be pulled out from the plug-in component 4, so as to achieve the effect of simple operation and convenient installation and disassembly. Specifically, it includes a deep foundation pit 1, a waist beam 2 arranged horizontally is provided on one side of the deep foundation pit 1, a detachable connection component 3 is provided on the waist beam 2, and a plurality of plug-in components 4 spaced apart and opened toward one side of the waist beam 2 are provided in the deep foundation pit 1, a plug-in groove corresponding to the plug-in component 4 is first opened on the side wall of the deep foundation pit 1, and then the plug-in component 4 is fixed in the plug-in groove.

[0032] When the connection component 3 is not needed, it can be stored in the storage groove 5. When it is needed, the connection component 3 can be taken out from the storage groove 5 and then placed in the installation groove 6. Then, the connection component 3 can be slid into the plug-in component 4 to facilitate storage and use. Specifically, a storage groove 5 with an opening facing upward is provided on the top of the waist beam 2. The connection component 3 and the storage groove 5 correspond to each other. The connection component 3 can be detachably plugged into the storage groove 5. After the connection component 3 is removed from the waist beam 2 and the deep foundation pit 1, the connection component 3 is turned over and inserted into the storage groove 5, so that the connection component 3 can be conveniently stored to avoid loss when not in use.

[0033] The top opening of the waist beam 2 has an installation groove 6 which opens upward and is transparent on the front side (the installation groove 6 includes an insertion groove and a sliding groove, and the sliding groove has the same cross-sectional shape as the connecting component 3). The installation groove 6 is located on the front side of the storage groove 5. The connecting component 3 and the installation groove 6 correspond to each other. The connecting component 3 can be removably slidably arranged in the installation groove 6. When the waist beam 2 needs to be connected to the deep foundation pit 1, the connecting component 3 is first taken out from the storage groove 5, and then turned over and inserted into the insertion groove of the installation groove 6. Since the installation groove 6 has a sliding groove of the same shape as the connecting component 3, after insertion, the connecting component 3 can be plugged into the plug-in component 4 along the sliding groove, so that the deep foundation pit 1 and the waist beam 2 are connected to each other.

[0034] A plurality of spaced-apart plug-in slots with openings toward the waist beam 2 are provided on one side of the deep foundation pit 1 close to the waist beam 2. The plug-in assembly 4 is fixed in the plug-in slot, and the upper plug-in component 401 and the lower plug-in component 402 are respectively installed in the corresponding plug-in slots.

[0035] By setting the upper block 301 and the lower block 302, during the connection process, the upper block 301 and the lower block 302 are both plugged into the plug-in component 4, which can effectively prevent loosening during use so as to improve stability. Specifically, the connecting component 3 is plugged into the plug-in component 4, and the connecting component 3 and the plug-in component 4 cooperate with each other to fix the deep foundation pit 1 and the waist beam 2. When the connecting component 3 is plugged into the plug-in component 4, it can withstand a larger load and ensure the reliability of the connection. Moreover, it is easier to install and disassemble than bolts.

[0036] The plug-in assembly 4 includes an upper-level plug-in component 401 and a lower-level plug-in component 402 . The upper-level plug-in component 401 is located above the lower-level plug-in component 402 , and the upper-level plug-in component 401 is a hexagonal structure.

[0037] The connecting assembly 3 can be plugged into the upper-level plug-in component 401 and the lower-level plug-in component 402 .

[0038] A plurality of upper limiting plates 7 are fixedly provided on the inner side wall of the upper connector 401 , which are arranged in an array with intervals around the upper connector 401 and extend in the front-to-back direction.

[0039] An extension frame 8 is fixedly provided on the inner side wall of the lower-level connector 402, and the extension frame 8 is interconnected with the lower-level connector 402. A plurality of lower-level limiting plates 9 are fixedly provided on the inner side wall of the extension frame 8, which are spaced apart from each other and extend in the front-to-back direction. The setting of the upper limiting plates 7 and the lower limiting plates 9 can improve the connection stability of the connecting component 3 and the plug-in component 4, making the connection more stable.

[0040] The connection assembly 3 includes an upper block 301 , a lower block 302 and a vertical rod 303 . The upper block 301 and the lower block 302 are both extended in the front-rear direction and are fixedly connected to the vertical rod 303 .

[0041] The upper block 301 is provided with a plurality of upper grooves 10 which are arranged in an array with the upper block 301 as the center and extend in the front-to-back direction. The upper grooves 10 open toward one side of the deep foundation pit 1. When the upper block 301 is inserted into the upper connector 401, the upper limit plate 7 is inserted into the upper groove 10. When the vertical rod 303 moves along the mounting groove 6, the upper block 301 can be inserted into the upper connector 401. At this time, the upper limit plate 7 is also inserted into the upper groove 10, so that the upper block 301 and the upper connector 401 are plugged into each other, thereby improving the connection stability.

[0042] The lower-level block 302 is plugged into the lower-level plug-in component 402 .

[0043] A protrusion 11 is fixedly provided on the front side of the lower block 302 , and a lower groove 12 with an opening facing forward and extending in the front-rear direction is formed on the protrusion 11 .

[0044] When the lower block 302 is inserted into the lower connector 402, the protrusion 11 can be inserted into the extension frame 8, and the lower limit plate 9 is inserted into the lower groove 12. When the lower block 302 is inserted into the lower connector 402, the protrusion 11 can be driven to be inserted into the extension frame 8. At this time, the lower limit plate 9 is inserted into the lower groove 12. By mutual insertion, the firmness of the connection is improved to avoid looseness.

[0045] Working principle: Before use, a plug-in slot corresponding to the plug-in component 4 is opened on the side wall of the deep foundation pit 1, and then the upper plug-in component 401 and the lower plug-in component 402 are respectively fixed in the plug-in slot, and the waist beam 2 is placed at the corresponding position of the deep foundation pit 1.

[0046] When the waist beam 2 needs to be connected to the deep foundation pit 1, the connecting component 3 is first taken out from the storage groove 5, and then turned over and inserted into the insertion groove of the installation groove 6. Since the installation groove 6 has a sliding groove of the same shape as the connecting component 3, after insertion, the connecting component 3 can be plugged into the plug-in component 4 along the sliding groove, so that the deep foundation pit 1 and the waist beam 2 are connected to each other.

[0047] When the vertical rod 303 moves along the installation groove 6, the upper block 301 can be inserted into the upper connector 401. At this time, the upper limit plate 7 is also inserted into the upper groove 10, so that the upper block 301 and the upper connector 401 are plugged into each other. At the same time, the lower block 302 is inserted into the lower connector 402, driving the protrusion 11 to be inserted into the extension frame 8. At this time, the lower limit plate 9 is also inserted into the lower groove 12. By plugging into each other, the firmness of the connection is improved to avoid looseness.

[0048] After the connection assembly 3 is removed from the waist beam 2 and the deep foundation pit 1, the connection assembly 3 is turned over and inserted into the storage groove 5, so that the connection assembly 3 can be conveniently stored to avoid loss when not in use.
