[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Please see Figure 1-6A type F-shaped concrete jacking pipe includes a jacking pipe body 1. Eight semi-circular positioning grooves 2 are opened on the circumferential side of the jacking pipe body 1. The semi-circular positioning grooves 2 are located on the circumferential side of the jacking pipe body 1. Multiple insertion slot plates 4 are fixed inside the semi-circular positioning grooves 2. Hexagonal socket bolts 3 are fixed between the insertion slot plates 4 and the jacking pipe body 1. The insertion slot plates 4 and the jacking pipe body 1 are connected through the hexagonal socket bolts 3. A circular washer is installed between the hexagonal socket bolts 3 and the jacking pipe body 1. The insertion slot plates 4 have threaded connection holes that do not penetrate through the pipe. A mating connection through hole is opened inside the semi-circular positioning grooves 2. The mating connection through hole and the threaded connection hole are opened in the same position. A mating slot is opened at the top of the jacking pipe body 1. A plug-in locking block is welded to the bottom of the filling sealing cap 5. The plug-in locking block and the mating slot are in clearance fit. A sealing ring is also installed between the plug-in locking block and the mating slot.

[0027] The top of the jacking pipe body 1 is snapped with a matching injection sealing cap 5, and the top of the matching injection sealing cap 5 is welded with multiple matching guide posts 6, and the top of the matching guide posts 6 is fixed with an injection anti-solidification structure 16.

[0028] The anti-coagulation structure 16 includes an inner flow pipe 7, an inner housing shell 8, an inner circulation sealing block 9, a water storage tank 10, a bidirectional water pipe 11, a discharge pipe 12, an inlet pipe 13, a water storage tank 14, and a circulating water pipe 15. The top and bottom ends of the inner housing shell 8 are welded to the inner circulation sealing block 9. The water storage tank 10 is located inside the inner circulation sealing block 9. The inner side of the inner circulation sealing block 9 and the inner side of the inner housing shell 8 are fixedly connected to the inner flow pipe 7. There is a five-centimeter gap between the inner surface of the inner housing shell 8 and the outer surface of the inner flow pipe 7. The inner circulation sealing block 9 located at the top of the inner housing 8 and the inner circulation sealing block 9 located at the bottom of the inner housing 8 are connected by multiple bidirectional water pipes 11. The bidirectional water pipes 11 are welded to the inner circulation sealing block 9, and the bidirectional water pipes 11 are located within a five-centimeter distance. One side of the inner circulation sealing block 9 is welded to the inlet water pipe 13. The inside of the inlet water pipe 13 is inserted into the circulation water pipe 15. The other end of the circulation water pipe 15 is fixedly connected to the water storage tank 14. The outside of the inner circulation sealing block 9 is fixedly connected to the discharge pipe 12.

[0029] The top of the inner circulation sealing block 9 located at the top of the inner housing 8 is welded to the discharge pipe 12, and the bottom of the inner circulation sealing block 9 located at the bottom of the inner housing 8 is welded to the discharge pipe 12. The discharge pipe 12 has internal threads, and the guide post 6 has external threads. The bottom of the anti-solidification structure 16 is threaded to the top of the guide post 6, which facilitates the overall fixed connection of the anti-solidification structure 16 and the connection of the external injection pipe, forming a stable conductive connection and airtightness.

[0030] One end of the circulating water pipe 15 is equipped with a miniature water pump, which is fixed inside the water storage tank 14. The circulating water pipe 15 is connected to the water storage tank 14 through the miniature water pump, which facilitates the pumping of water from inside the water storage tank 14 into the inner circulation block 9. The water is then guided to form a circulation, thus blocking the external high temperature and keeping the internal moisture moist.

[0031] Working principle: By fixing a corresponding number of spigot slot plates 4 inside the main body 1 of the jacking pipe according to the processing and use requirements of the F-type pipe, the device can directly obtain the spigot slots after grouting and plasticization, avoiding the waste of manpower and time to open the spigot slots. During the grouting process, the matching injection cap 5 is inserted into the top of the main body 1 of the jacking pipe, and the connection is completed by the matching guide column 6 and the matching discharge pipe 12 at the bottom of the injection anti-solidification structure 16. The matching discharge pipe 12 at the top of the injection anti-solidification structure 16 is connected to the external feed pipe, so that a good limit is formed during the concrete grouting process, avoiding external splashing. During the process, a miniature water pump at one end of the circulating water pipe 15 draws water from inside the storage tank 14 into the top inner circulation block 9, causing the water to accumulate inside the storage tank 10. The water then flows through the bidirectional water pipe 11 to the storage tank 10 inside the lower inner circulation block 9. The water is then guided back into the storage tank 14 by the suction of the miniature water pump through the other circulating water pipe 15, forming a water circulation. During the circulation process, the heat generated by the high external temperature is absorbed by the specific heat capacity of the water and then circulated and transferred, preventing the heat from being conducted to the non-conductive concrete in the inner circulation pipe 7. This makes it easier for the concrete to keep itself moist and prevents it from solidifying during the conduction process.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
