Description

Technical Field

[0001] The embodiments of this utility model belong to the field of foundation pit support construction technology, and more specifically, relate to a detachable internally supported vortex well support steel casing. Background Technology

[0002] Swirl wells, as important industrial structures, are widely used in sewage treatment, water supply and drainage, and other fields. During their construction, the foundation pit support technology is a crucial link in ensuring construction safety and quality. Steel casing support technology, due to its advantages such as fast construction speed, high safety, and minimal environmental impact, has gradually become the preferred support method in swirl well construction. Steel casings are installed through prefabrication and sinking, effectively reducing construction time. They can serve as both the foundation pit support structure for swirl wells and the external formwork for concrete pouring, simplifying the construction process and significantly reducing construction costs. Despite the numerous advantages of steel casing support technology, some problems still exist in the design of traditional steel casings in practical applications. During the construction of vortex well steel casing support, after the steel casing has sunk, when constructing the main body of the vortex well, the reinforcement binding of the well wall needs to maintain a certain distance from the steel casing wall (protective layer thickness, generally less than 100mm). The distance is small, and when the inner support ring beam is welded to the casing, it will occupy a certain space. The conflict between the reinforcement binding and the inner support position makes it impossible to bind the reinforcement in the original design position. It is necessary to adjust the position of the reinforcement or anchor the reinforcement to the inner support ring beam, which involves a huge amount of work and affects the construction progress and cost. Utility Model Content

[0003] In view of the above-mentioned defects or improvement needs of the existing technology, this utility model provides a detachable internal support vortex well support steel casing. By setting a locking block hook, the steel casing and the inner support ring beam can be detachably connected. This not only does not affect the binding of the well wall reinforcement and reduces the amount of on-site welding work, but also simplifies the installation process, shortens the construction period, and reduces costs.

[0004] To achieve the above objectives, this utility model provides a detachable internally supported vortex well support steel casing, including a steel casing, an inner support ring beam, and a locking hook connecting the two.

[0005] The inner support ring beam is made of finished H-beam or welded H-beam, with one end flange plate attached to the steel casing and snapped above the hook of the clip block;

[0006] The locking hook is Z-shaped, with one end welded to the steel casing and the other end locking the inner support ring beam.

[0007] Furthermore, the steel casing includes a cylinder body, which is made of steel plate and has the same outer diameter as the vortex well design.

[0008] Furthermore, the steel casing also includes vertically added ribs to increase the strength of the steel casing.

[0009] Furthermore, the inner support ring beam is an arc-shaped plate with the same curvature as the steel casing, and it is spaced apart along the height direction of the steel casing.

[0010] Furthermore, the locking hooks are evenly distributed along the circumference of the steel casing.

[0011] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0012] (1) The inner support ring beam of the detachable internally supported vortex well support steel casing of this utility model is made of finished H-beams or welded H-beams. The H-beams are processed to have an arc consistent with the arc of the casing. The steel casing and the inner support ring beam are connected by welded clips and hooks, which is convenient for disassembly. This overcomes the problem of huge workload in the traditional method when the inner support ring beam is welded to the casing, where the reinforcement binding conflicts with the inner support and the reinforcement needs to be anchored to the inner support ring beam. This structure facilitates the removal of the ring beam after the casing is sunk, shortens the construction period, and saves construction costs.

[0013] (2) In this utility model, a steel plate is used to connect the detachable inner support vortex well support steel casing and the inner support ring beam. The steel plate is used to make a hook. The hook is in the shape of a Z. One end is welded to the inner wall of the steel casing, and the other end is used to lock the inner support ring beam to prevent the ring beam from coming off the hook.

[0014] (3) The detachable internal support vortex well support steel casing of this utility model has a simple structure. The internal support ring beam can be installed and disassembled by snap-fitting, which is simple to operate and improves construction efficiency. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0021] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] In this invention, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0024] like Figure 1-3As shown, this utility model embodiment provides a detachable internally supported vortex well support steel casing, including a steel casing 1, an internal support ring beam 2, and a locking hook 3. One end of the locking hook 3 is welded to the steel casing 1, and the other end locks the internal support ring beam 2. The internal support ring beam 2 is locked to the steel casing 1 body by the locking hook 3 and is not directly welded to the steel casing 1 body. This facilitates the removal of the internal support ring beam when the internal support occupies the space for the structural steel reinforcement during the subsequent construction of the vortex well body. This does not affect the binding of the well wall reinforcement, saves material for the internal support ring beam, improves construction efficiency, and reduces costs.

[0025] Specifically, the steel casing 1 includes a casing 101 and ribs 102. The steel casing 1 serves as both a support structure for the vortex well and an external formwork for its construction. Its height is prefabricated in sections according to the construction height of the vortex well. The casing 101 is manufactured according to the structure of the vortex well, and its outer diameter is strictly customized according to the specific structural requirements of the vortex well to ensure consistency with the designed outer diameter of the vortex well, thereby providing the best support effect and ensuring construction accuracy. The casing 101 is made of 8mm steel plate. For strata with high lateral soil pressure, the thickness is increased based on geological conditions. In addition, to further improve the strength of the steel casing 1, ribs 102 can be added vertically to the steel casing 1 as needed to improve the overall rigidity of the entire structure.

[0026] The inner support ring beam 2 is annular, made of pre-cast or welded H-beams. The H-beams are machined into arc-shaped plates with an arc radius matching that of the cylinder 101 of the steel casing 1, and the diameter of the arc-shaped plate is slightly smaller than the diameter of the cylinder 102. This ensures uniform pressure distribution after installation. The inner support ring beams 2 are spaced apart along the height of the cylinder 102 of the steel casing 1, with the spacing determined based on the depth of the vortex well, geological conditions, and stress analysis during construction. The installation of the inner support ring beam 2 ensures that the steel casing 1 does not deform during its descent, maintaining its roundness.

[0027] The locking hook 3 is made of 8mm or 10mm thick steel plate. It is Z-shaped and located at the lower end of the inner support ring beam 2. It is evenly distributed along the circumference of the steel casing 1 cylinder 102 to ensure that the cylinder 102 is subjected to uniform force in all directions. One end is welded to the inner wall of the steel casing 1 cylinder 102, and the other end locks the flange plate of the inner support ring beam 2, effectively preventing the inner support ring beam 2 from sliding downward or tilting due to its own weight.

[0028] During construction, the steel casing 1 is first pre-supported in sections according to the height of the vortex well. One end of the locking hook 3 is welded to the inner side of the casing 102 according to the circumferential and vertical design spacing. Then, one end of the inner support ring beam 2 is attached to the casing 102 of the steel casing 1 and secured above the locking hook 3 to complete the installation of the inner support ring beam 2. After the installation of the inner support ring beam 2, the inner support is welded to it. On-site measurement and layout are carried out. A crane is used to vertically lower the assembled steel casing in sections. Once the steel casing is completely sunk to the predetermined position, the inner support ring beam and inner support are removed. The vortex well wall reinforcement is then tied inside the steel casing. Finally, the vortex well wall concrete is poured, completing the entire construction project. During construction, if a conflict is found between the inner support and the well wall reinforcement, the relevant inner support and inner support ring beam 2 can be quickly removed, ensuring that the well wall reinforcement tying is not affected.

[0029] This utility model of steel casing structure not only simplifies the installation process and reduces on-site welding work, but also makes dismantling very convenient without damaging the steel casing or other components. In this way, the internal support structure can be flexibly adjusted without affecting the reinforcement binding of the well wall, improving the overall construction flexibility and efficiency, and significantly reducing costs.

[0030] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
