[0026] In order to enable those skilled in the art to better understand the disclosed solution, the technical solution in the disclosed embodiment will be clearly and completely described below in conjunction with the drawings in the disclosed embodiment. Obviously, the described embodiment is only a part of the disclosed embodiment, not all of the embodiments. Based on the embodiments in the disclosed embodiment, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the disclosed embodiment.

[0027] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described can be implemented in sequences other than those illustrated or described herein.

[0028] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not explicitly listed or inherent to these processes, methods, products, or apparatuses.

[0029] For ease of understanding and explanation, the following Figures 1 to 4 The detachable conductor pipe frame and casting mechanism for underwater concrete casting of pile foundation provided by the embodiments of the present disclosure are described in detail.

[0030] Please refer to Figure 1 , which is a schematic diagram of the top structure of a detachable catheter rack provided in an embodiment of the present disclosure. The detachable catheter rack 1 includes a frame body 11, a groove 12 provided on the frame body 11 through which the catheter 2 can be placed, and two oppositely arranged movable clamps 13 located on the outer surface of the groove 12, the two movable clamps 13 are close to each other when the catheter 2 is fixed, and are away from each other when the catheter 2 is taken out. The embodiment of the present disclosure utilizes the opening and closing of the groove 12 and the sliding clamp 13 to separate the catheter 2 from the catheter rack 1, thereby facilitating and quickly constructing operations, and greatly improving the quality and efficiency of hole cleaning. It should be noted that the embodiment of the present disclosure can manufacture the detachable catheter rack 1 according to the diameter of the catheter and the diameter of the pile, for example, the diameter of the catheter is 320 mm, and the maximum diameter of the pile foundation is 2.8 m.

[0031] Combine the following Figures 2 to 3 As shown, the various components of the detachable conductor rack 1 in the embodiment of the present disclosure are explained. For example, the frame body 11 includes a skeleton and a steel plate 111 laid on the skeleton, and the skeleton includes interconnected industrial steel 112 and square steel. For example, the length of the frame body 11 is 4m, the width is 1m and the height is 0.2m, 20cm×20cm square steel is used as a load-bearing beam, I20a industrial steel is used as a tie beam and square steel to form a skeleton, and a steel plate 111 with a thickness of 1cm is laid on the skeleton as an operating platform. A 40cm×40cm groove 12 is opened in the middle position of the frame body 11 as a lower opening for the conductor. The groove 12 is welded with I20a industrial steel around it for strength compensation, thereby ensuring the stability of the force of the conductor rack 1, and the two movable clamps 13 on the outer surface of the groove 12 can be used to install the conductor.

[0032] Furthermore, the square steel at the notch of the groove 12 of the frame body 11 is movably connected to the frame through the ear plate 113 and the latch, that is, the square steel at the notch can be pulled out of the frame body 11. For example, the movable square steel is connected to the other three sides through the ear plate 113, and a latch with a diameter of 5 cm is used to achieve limited fixation, that is, the ear plate 113 is provided with a latch hole. In addition, the corners of the frame body 11 can also be provided with lifting ears 114, which has the advantage of facilitating the lifting and transportation of the pipe rack 1.

[0033] For another example, one end of the movable card plate 13 is hinged to the frame body 11, while the other end of the movable card plate 13 is suspended, that is, a folding method is adopted. Alternatively, a sliding member is provided between the movable card plate 13 and the frame body 11, that is, a sliding method is adopted, for example, the sliding member includes but is not limited to a sliding protrusion located on the movable card plate 13 and a sliding groove located on the frame body 11 and adapted to the sliding protrusion, or the sliding member includes but is not limited to a sliding groove located on the movable card plate 13 and a sliding protrusion located on the frame body 11 and adapted to the sliding groove, which meets the diverse use requirements. Further, the sliding protrusion may include a pulley. The advantage of such a setting is that the sliding is smooth and the service life is extended. At the same time, the movable card plate 13 can be replaced according to the diameter of the catheter and the pile diameter, which is convenient for repeated use and reduces the production cost. Optionally, a handle 131 may also be provided on the movable card plate 13, thereby facilitating the movement of the movable card plate 13 and being more humane.

[0034] During actual construction, first assemble the detachable conduit rack 1 into a whole, place it on the lower rack of the steel cage, and install the conduit 2 and the air duct; secondly, after the conduit 2 and the air duct are installed, use the crane hook to lift the conduit 2, and open the latch to pull out the movable square steel of the conduit rack 1; thirdly, use the crane hook to lift the conduit rack 1 out of the pile position to take the conduit 2 out of the conduit rack 1, and turn on the air compressor, use the crane hook to lift the conduit 2 for secondary hole cleaning, and continuously move the conduit position and adjust the conduit depth during the hole cleaning process, thereby improving the secondary hole cleaning efficiency and hole cleaning quality; finally, after the secondary hole cleaning is qualified, use the crane hook to lift the conduit rack 1 at the pile position to enclose the conduit rack on all sides, and insert the latch so that the conduit 2 falls on the conduit rack 1, and install the large hopper to prepare for pouring concrete.

[0035] The detachable catheter rack provided by the disclosed embodiment has a groove on the frame body and two movable clamps installed on the outer surface of the groove, so that when the catheter is fixed, the two movable clamps can be close to each other, and when the catheter is taken out, the two movable clamps can be separated from each other, that is, the catheter can be separated from the catheter rack by opening and closing the groove and the sliding clamp, which facilitates and speeds construction operations and greatly improves the hole cleaning quality and efficiency.

[0036] Based on the above embodiments, the present disclosure provides a pouring mechanism. Figure 4 , which is a side view structural diagram of a casting mechanism provided in an embodiment of the present disclosure, the casting mechanism 3 includes a conduit 2 and Figures 1 to 3 The detachable catheter frame 1 of the corresponding embodiment.

[0037] It should be noted that, for the description of the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0038] The pouring mechanism provided by the disclosed embodiment has a detachable conduit rack in which a groove is provided on the frame body and two movable clamps are installed on the outer surface of the groove, so that when the conduit is fixed, the two movable clamps can be close to each other, and when the conduit is taken out, the two movable clamps can be moved away from each other, that is, the conduit can be separated from the conduit rack by opening and closing the groove and the sliding clamp, which facilitates and speeds the construction operation and greatly improves the hole cleaning quality and efficiency.
