Abstract
Description
Technical Field
[0001] This utility model relates to the field of well structure technology, and more specifically, to a steel well with a ring-shaped gripping rib reinforced structure. Background Technology
[0002] Steel wells are widely used in urban infrastructure construction, industrial storage tanks, and the petrochemical and energy sectors. For ease of processing and transportation, traditional steel wells are mostly smooth cylinders. While this facilitates construction and reduces costs, in areas with soft soils, collapsible soils, or high groundwater levels, the well body is prone to subsidence, displacement, or rotation after backfilling, which can affect pipeline joint sealing and compromise structural stability. Although some wells have attempted to enhance stability by adding concrete wrapping layers or welding additional components, these methods are complex and offer limited improvement in soil adhesion. Therefore, a well structure that is simple in design, highly robust, and adaptable to a wide range of geological conditions is needed.
[0003] Improving the overall stability and compressive and tensile strength of steel wells is an important direction for their development. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel well with a ring-shaped gripping rib reinforced structure, comprising a cylindrical well body, wherein the outer wall of the well body is provided with multiple ring-shaped gripping ribs along the vertical direction, the gripping ribs are closed ring structures, and are fixedly connected to the outer surface of the well body by welding or integral stamping, and the gripping ribs are evenly distributed along the height direction of the well body.
[0005] Preferably, the width, thickness, and spacing of the annular gripping ribs can be flexibly adjusted according to the size of the steel well, and the spacing in the middle and bottom areas of the well body is smaller than that in the upper area, forming a reinforced structural zone.
[0006] Preferably, the gripping rib is made of Q235 or Q355 material and is coated with an epoxy anti-corrosion coating or subjected to hot-dip galvanizing anti-corrosion treatment.
[0007] Preferably, the width of the top and bottom plates of the well body is greater than the outer diameter of the well body cylinder, forming a widened structure to increase the stress-bearing area; the edges of the top and bottom plates can be designed as flanged structures to enhance the interlocking force with the soil.
[0008] Preferably, the gripping rib is connected to the well body by continuous full welding, or partially embedded in the reserved groove in the well wall to form a semi-embedded connection structure.
[0009] Preferably, the bottom of the well body is provided with reinforced ring ribs or a bottom sealing plate to enhance the bottom bearing capacity and deformation resistance.
[0010] Preferably, the cross-sectional shape of the annular gripping rib is trapezoidal or triangular to increase the coefficient of friction and interlocking force with the soil.
[0011] Compared with existing technologies, the beneficial effects of this utility model are: 1. The multi-ringed gripping ribs (closed circular structure) on the outer wall of the well body are tightly embedded with the backfill soil. By increasing the contact area and surface roughness, the frictional resistance and interlocking force between the well body and the soil are significantly improved. For example, in areas with high groundwater levels, the gripping ribs embedded in the soil form a "mechanical anchoring" effect, which can improve the well body's resistance to uplift and effectively resist the problem of well body uplift caused by groundwater buoyancy.
[0012] 2. The spacing of the gripping ribs is reduced in the middle and bottom areas of the well body (forming a reinforced structural zone) to specifically address the high pressure and fluidity of deep soil. In soft soil or collapsible loess layers, the denser gripping ribs at the bottom can improve the well body's resistance to sliding, prevent horizontal displacement or rotation caused by soil lateral pressure, and ensure that the pipe joint seal is not damaged.
[0013] 3. The width of the top and bottom plates is greater than the outer diameter of the well cylinder. By increasing the load-bearing area, the ground load is evenly transferred to the surrounding soil, reducing settlement and deformation at the top of the well. The widened design reduces the amount of top settlement and is suitable for heavy-load scenarios such as main traffic arteries and industrial plants.
[0014] 4. The flanged structure at the edges of the top and bottom slabs, once embedded in the soil, creates a "barb" effect, effectively enhancing the interfacial shear strength. In earthquake-prone areas or environments with soil vibration, the flanged design can improve the well's resistance to tilting, reducing the risk of structural damage caused by soil displacement.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Referring to the figure, this embodiment provides a steel well with an annular gripping rib reinforced structure, including a cylindrical well body 1. The outer wall of the well body 1 is provided with multiple annular gripping ribs 2 in the vertical direction. The gripping ribs 2 are closed circular structures and are fixedly connected to the outer surface of the well body 1 by welding or integral stamping. The gripping ribs 2 are evenly distributed along the height direction of the well body 1.
[0019] Furthermore, the width, thickness, and spacing of the annular gripping ribs 2 can be flexibly adjusted according to the size of the steel well, and the spacing in the middle and bottom areas of the well body 1 is smaller than that in the upper area, forming a reinforced structural zone.
[0020] Furthermore, the gripping rib 2 is made of Q235 or Q355 material, and its surface is coated with an epoxy anti-corrosion coating or subjected to hot-dip galvanizing anti-corrosion treatment.
[0021] Furthermore, the top and bottom plates of the well body 1 are wider than the outer diameter of the well cylinder, forming a widened structure to increase the stress-bearing area; the edges of the top plate 3 and bottom plate 4 can be designed as flanged structures to enhance the interlocking force with the soil.
[0022] Furthermore, the gripping rib 2 is connected to the well body 1 by continuous full welding, or partially embedded in the reserved groove in the well wall to form a semi-embedded connection structure.
[0023] Furthermore, the bottom of the well body 1 is provided with reinforced ring ribs or a bottom sealing plate to enhance the bottom bearing capacity and resistance to deformation.
[0024] Furthermore, the cross-sectional shape of the annular gripping rib 2 is trapezoidal or triangular to increase the coefficient of friction and interlocking force with the soil.
[0025] In the above embodiment, during installation, the steel well body 1 is first hoisted to the predetermined position, and the surrounding soil is backfilled and compacted.
[0026] During the installation process described above, the designed annular gripping rib 2 is in full contact with the soil, and its structure is embedded in the soil to form a strong gripping force; the widened top plate 3 and bottom plate 4, as well as the processable flange 5 structure are tightly integrated with the soil, which can effectively disperse the upper load and resist the bottom buoyancy, preventing the well body from floating or tilting.
[0027] In other embodiments of this utility model, the cross-section of the annular gripping rib 2 can be designed as a trapezoid or a triangle; the outer diameter of the top plate 4 and the bottom plate 5 can be adjusted to twice the outer diameter of the well body, and the flange height can be adjusted according to actual needs.
[0028] The device described in the above embodiments significantly enhances the friction and gripping force between the well body and the surrounding soil by incorporating annular gripping ribs on the outer wall of the steel well body. This results in a uniform gripping force distribution, effectively preventing the well body from floating or tilting. The rough or raised outer surface structure of the annular gripping ribs further increases the interlocking force with the soil, adapting to various geological conditions. The widened design of the top and bottom plates increases the contact area between the well body and the soil, dispersing the upper load, improving the bottom's anti-buoyancy capability, and enhancing overall stability. The flanged structure of the top and bottom plates further improves the interlocking force with the soil and optimizes the stress distribution of the well body.
[0029] This device has a simple structure, is easy to construct, and is inexpensive, making it suitable for steel well bodies of various specifications.
[0030] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto.
