PREFERRED EMBODIMENT

[0020] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the range of protection of the utility model.

[0021] As Figures 1 to 4The utility model provides a detachable device for providing the sinking structure with the downward pressure, comprising counterforce anchor cable 1, the outer surface fixedly connected with detachable steel corbel 2 of counterforce anchor cable 1, one end of detachable steel corbel 2 is equipped with corbel embedded component 3, detachable steel corbel 2 is fixedly connected with the sinking structure 4 of being like through corbel embedded component 3, the combination of counterforce anchor cable 1, detachable steel corbel 2 and corbel embedded component 3 realizes the effective transmission of the downward pressure to sinking structure 4, provides the stable force source for structure sinking, and the connection of each component is clear, and the overall structure is strong.

[0022] Specifically, the corbel embedded component 3 is composed of a plurality of embedded high-strength bolts 302 and embedded steel plates 301, which are embedded in the structure. The corbel embedded component 3 composed of the embedded steel plates 301 and the embedded high-strength bolts 302 is pre-set during the construction phase of the structure, providing a firm foundation for the installation of the detachable steel corbel 2, ensuring the reliability of force transmission, and the embedded method does not affect the original performance of the sinking structure 4.

[0023] As shown in Figures 1 to 4 The detachable steel corbel 2 is composed of a top steel plate 201, a back steel plate 202, and two steel rib plates 203. The top steel plate 201 has a through-type reserved anchor cable hole 204 at the top end. The detachable steel corbel 2 is made of welding, which has high structural strength and can withstand large tension and pressure. The reserved anchor cable hole 204 of the top steel plate 201 provides a channel for the installation of the counterforce anchor cable 1, ensuring the precise cooperation between the anchor cable and the steel corbel, and the smooth force transmission path.

[0024] Furthermore, the back steel plate 202 has a plurality of reserved bolt holes 205, which correspond to the exposed positions of the plurality of embedded high-strength bolts 302. The embedded high-strength bolts 302 are used to quickly assemble and disassemble the corbel embedded component 3, saving time and effort, and effectively improving construction efficiency. The corresponding design of the reserved bolt holes 205 and the embedded high-strength bolts 302 enables quick installation and disassembly of the detachable steel corbel 2 and the corbel embedded component 3, simplifying the construction process, reducing construction time and labor costs, and significantly improving construction efficiency. At the same time, it is convenient for the maintenance and replacement of the parts in the later stage.

[0025] As shown in Figures 1 to 4 The counterforce anchor cable 1 is composed of an anchor cable free section 101 and an anchor cable anchoring section 102. The anchor cable anchoring section 102 is fixedly connected with the underlying foundation, dividing the counterforce anchor cable 1 into the anchor cable free section 101 and the anchor cable anchoring section 102. The anchoring section is fixedly connected with the foundation, which can provide reliable counterforce support for the entire device by the stability of the foundation, ensuring the stability of the device as a whole during the application of downward pressure, and avoiding the displacement of the structure due to insufficient counterforce.

[0026] It is worth noting that a through-hole jack 5 is provided at the anchor head end of the free section 101 of the anchor cable, and the bottom of the through-hole jack 5 abuts against the top of the top steel plate 201 to apply the pulling force to the detachable steel corbel 2. The cooperation between the through-hole jack 5 and the anchor head end of the free section 101 of the anchor cable, as well as the abutment design with the top steel plate 201, can accurately apply the pulling force generated by the jack to the detachable steel corbel 2, thereby realizing effective output and transmission of force and ensuring the controllability of the downward force.

[0027] like Figures 1 to 4 As shown, the anchor head of the free section 101 of the anchor cable is adapted to the through-hole jack 5, and the through-hole jack 5 transmits the pulling force to the detachable steel corbel 2 through the top steel plate 201. The adaptive design of the anchor head of the free section 101 of the anchor cable and the through-hole jack 5 ensures the tightness and reliability of the connection between the two, and avoids the loss in the force transmission process; the pulling force is transmitted to the steel corbel through the top steel plate 201, which further optimizes the force transmission path, improves the force transmission efficiency, and enables the downward force to stably act on the proposed sinking structure 4.

[0028] Working principle and process: After the through-hole jack 5 is started, a pulling force is applied to the free section 101 of the anchor cable. Since the anchoring section 102 of the anchor cable is fixedly connected to the foundation below, under the action of the pulling force, the free section 101 of the anchor cable will generate an upward pulling force, and this pulling force is transmitted to the through-hole jack 5 through the anchor head, and the bottom of the through-hole jack 5 is in contact with the top steel plate 201 of the detachable steel corbel 2. According to the principle of action and reaction force, the through-hole jack 5 will generate downward pressure on the top steel plate 201, and this pressure is transmitted to the proposed sinking structure 4 through the detachable steel corbel 2 and the corbel embedded component 3, thereby providing the required downward pressure for the proposed sinking structure 4 and realizing controllable sinking of the structure.
