[0020] Please see Figure 1-4 This utility model provides a technical solution:

[0021] A prefabricated reinforced concrete well chamber includes a well shaft 1. A grout inlet hole 2 is provided on the inner wall of the well shaft 1. Waterproof adhesive grooves 3 are provided on both the upper and lower sides of the well shaft 1. A sliding groove 12 and a positioning groove 15 are provided on the top of the well shaft 1. Wedge-shaped grooves 5 are provided on both the upper and lower sides of the inner wall of the well shaft 1. Wedge-shaped blocks 4 are bolted into some of the wedge-shaped grooves 5. A lifting lug 6 is tightly fitted to the top of the well shaft 1. A positioning post 7 is fixedly connected to the bottom of the lifting lug 6. A connecting plate 8 is fixedly connected to one side of the positioning post 7. A hard block 9 is fitted inside the positioning post 7. A fixing plate 14 is fixedly connected to one side, and a slider 11 is fixedly connected to the outer side of the middle of the fixing plate 14. A fixing rod 10 is fixedly connected to one side of the slider 11. A long screw 13 is internally threaded onto the fixing rod 10. The connection structure set for the lifting lug 6 facilitates the fixing of the lifting lug 6. The fixing rod 10 and the slider 11 can be removed after moving in the slide groove 12 without affecting the assembly of the well shaft 1. The detachable lifting lug 6 avoids the process of cutting the lifting lug 6, making the disassembly of the lifting lug 6 more convenient and quick, and it can be reused.

[0022] The grout inlet hole 2 has an inverted L-shaped cross-section. The grout inlet hole 2 on one side of one shaft 1 and the positioning groove 15 on the top of the other shaft 1 are connected to each other, which facilitates the reinforcement and sealing between the two shafts 1. The bottom of each lifting lug 6 is fixedly connected to two positioning columns 7. A connecting plate 8 is fixedly connected between the two positioning columns 7. The positioning columns 7 and the connecting plate 8 are tightly fitted with the positioning groove 15, so that the lifting lug 6 has a positioning effect when installed. The slider 11 and the slide groove 12 are tightly fitted. The positioning groove 15 and the slide groove 12 are connected to each other, which facilitates grouting. One end of the long screw 13 is threadedly connected to the lifting lug 6. Several lifting lugs 6 are set in a group on the top of the shaft 1, which facilitates the further reinforcement of the lifting lug 6 and the use of the lifting lug 6.

[0023] Workflow: When using prefabricated reinforced concrete manholes, construction is carried out using a phased sinking method. Several manholes 1 and base plates are prefabricated in the factory and transported to the site for assembly. The site is leveled, surveyed, and the manhole positions are determined. One manhole 1 is transported to the appropriate position by hooking a rope onto the lifting lug 6. After placement, the lifting lug 6 needs to be disassembled. The user uses tools to turn the long screw 13 to one side until one end of the long screw 13 is away from the lifting lug 6. Then, holding the fixing plate 14, it is slid to one side, causing the slider 11 to move within the groove 12 opened at the top of the manhole 1. Simultaneously, the fixing rod 10 and the hard block 9 move in the same direction. The fixing rod 10 gradually moves away from the lifting lug 6, and the hard block 9 gradually moves away from the positioning column 7. At this point, the lifting lug 6, positioning column 7, and connecting plate 8 can be moved upwards as a whole until completely removed. Then, the slider 11 continues to move until it reaches the appropriate position. After moving the slider 11, fixing plate 14 and fixing rod 10 upwards as a whole, remove them. Then place the waterproof strip in the waterproof adhesive groove 3 and apply waterproof material to the outer wall. Then align the wedge block 4 with the wedge groove 5 and insert it, with the upper half of the wedge block 4 exposed. At this time, align the wedge groove 5 of the other well 1 with the exposed wedge block 4 and insert it. Then use bolts to fix the wedge block 4 and the two well 1s. At this time, grout the reserved grout inlet hole 2. Since the grout inlet hole 2 on one side of this well 1 and the sliding groove 12 on the top of the other well 1 are connected to the positioning groove 15, the two well 1s are reinforced and sealed. Several well 1s are spliced ​​together in the same way. After the assembly is completed, the bottom of the well 1 is backfilled with soil and sealed with concrete. Then the bottom of the steel plate is tied and the top is sealed with concrete weight to complete the construction. At the same time, the lifting lug 6 can be reused.
