[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0034] like Figure 1-Figure 15 As shown, the present application provides a multi-section locking device and its assembly and installation, including a locking assembly 10, which is used for building foundation treatment, bridge support, offshore platform, dock and embankment foundation support, high-rise building foundation reinforcement, etc. The device can be used for water enclosure, soil enclosure and sand enclosure, etc.

[0035] The locking assembly 10 includes an upper locking tube 11 and a lower locking tube 12. The upper locking tube 11 and the lower locking tube 12 are prefabricated in advance, which can greatly facilitate the transportation process. The upper locking tube 11 can be processed according to the on-site grooving depth, so as to meet the construction requirements of different depths.

[0036] The upper locking tube 11 and the lower locking tube 12 prefabricated in the factory are transported to the construction site and assembled according to the actual depth of the trench. During assembly, the total length of the locking assembly 10 assembled from the upper locking tube 11 and the lower locking tube 12 is the depth of the trench on site plus an additional 1m, so as to ensure that the locking assembly 10 has sufficient stability and adaptability in the trench.

[0037] The top diameter of the lower locking tube 12 is smaller than the bottom diameter of the upper locking tube 11, so that the lower locking tube 12 can be plugged into the upper locking tube 11. This connection method is not only easy to operate, but also can provide good connection stability. After the socket connection is completed, the connection between the upper locking tube 11 and the lower locking tube 12 will be welded to lock it firmly to ensure that it will not loosen or become disconnected during the subsequent construction process.

[0038] The upper locking pipe 11 is provided with a plurality of groups of bolt holes a13 at equal intervals, and bolts can be installed at the bolt holes a13. When tying the lifting wire rope, the bolts can be inserted into the corresponding bolt holes a13, thereby providing a stable supporting force point for the lifting. Similarly, during the pipe pulling operation, inserting the bolts can also effectively provide the required supporting force, making the entire lifting and pulling process safer and more efficient.

[0039] The assembled lock assembly 10 is accurately installed to the designated position of the excavated trench using a crane. During the installation process, the verticality of the lock assembly 10 is strictly guaranteed, which is crucial for the smooth progress of subsequent projects. The verticality can ensure that the lock assembly 10 is evenly stressed in the trench and avoid various problems caused by tilting.

[0040] In addition, the bottom of the lower locking tube 12 is a conical structure, which forms a downwardly inclined surface at the bottom of the lower locking tube 12. This shape design allows the lower locking tube 12 to be inserted into the soil of the groove more smoothly and can easily cut into the soil, thereby playing a good anchoring role. At the same time, it also enhances the overall stability of the locking assembly 10 in the groove and prevents it from displacement during construction.

[0041] The upper locking tube 11 and the lower locking tube 12 are both provided with air holes 14, and the air holes 14 can pass through the entire upper locking tube 11 and the lower locking tube 12, and the air holes 14 will leak on the surface of the upper locking tube 11 and the lower locking tube 12, and the bottom of the lower locking tube 12 is an open shape. The two designs cooperate with each other, and when installing the upper locking tube 11 and the lower locking tube 12, the air in the tube can be effectively removed to avoid buoyancy caused by air accumulation in the cavity. When pulling out the upper locking tube 11 and the lower locking tube 12, muddy water can leak out through the lower end opening and the air holes 14, thereby greatly reducing the gravity of the mud in the tube, thereby significantly reducing the weight of the pulling out, and making the pulling out operation more convenient.

[0042] A membrane lowering process for a multi-section locking device. After the locking assembly 10 is installed, the membrane lowering operation is performed immediately. The membrane body is inserted along the track chamber 15 in a sequence from top to bottom until the bottom elevation position required by the design is reached.

[0043] At the same time, a bag compartment 18 is opened on one side of the locking mouth tube 11 close to the track chamber 15. The bag compartment 18 has a semicircular structure and is mainly used to install a bag body (air bag or water bag) to provide key structural support for the subsequent sealing of the HDPE film.

[0044] When the two bladders are inflated with air or water, they will expand and clamp the HDPE film tightly. This sealing method can effectively prevent the backfill slurry from penetrating into the track chamber 15 of the lock assembly 10, thereby ensuring that the lock assembly 10 will not be immersed in the backfill and solidified, avoiding the situation where the stopper is blocked, and ensuring the sealing and stability between the HDPE film and the lock assembly 10.

[0045] The bottom of the lower locking tube 12 is fixedly installed with several groups of steel bars (not shown). The steel bars can be welded to the bottom of the lower locking tube 12. The function of the steel bars is to prevent large pieces of soil at the bottom from entering the locking assembly 10 during the construction process.

[0046] The upper lock pipe 11 is provided with a pipe installation hole 17, which is used to install pipes for inflating the bladder with air or water. For the convenience of operation, one end of these pipes is connected to the bladder, and the other end extends to the top of the lock assembly 10. With this design, both the inflation (water filling) and exhaust (drainage) operations can be performed at the top of the lock assembly 10, which greatly improves the convenience and safety of operation.

[0047] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
