Description

Technical Field

[0001] The utility model belongs to the technical field of steel sheet pile support, in particular to a steel sheet pile support device. Background Art

[0002] Steel sheet piles are a type of steel structure with a linkage device on the edge, and this linkage device can be freely combined to form a continuous and tight retaining wall or water retaining wall. Since steel sheet piles mainly bear the pressure from the outside, the inner side of the cofferdam structure formed by them needs to be supported. The usual supporting structure is a support column, that is, the support column is directly tilted to support the inner side of the steel sheet pile, or placed horizontally and directly supported on the inner wall of the steel sheet pile on both sides of the cofferdam. Regardless of the support method, the support column needs to be fixed. The welding fixation method is more stable, but it is not convenient for subsequent disassembly. The bolts are easily loosened in a vibrating environment, making it difficult to ensure stability. At the same time, installing the bolts one by one is also time-consuming and labor-intensive.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0020] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The present invention provides a steel sheet pile supporting device. Figure 1-5As shown, the steel sheet pile support device includes: a plurality of steel sheet pile bodies 1, each of which is in contact with the inner wall of the foundation pit; a plurality of clamping plates 2, each of which is fixed on one side of the plurality of steel sheet pile bodies 1, and each of which is U-shaped and can be clamped on one side of another steel sheet pile body 1; a plurality of support shafts 3, each of which is installed on the plurality of steel sheet pile bodies 1, and each of which is rotatably installed with a support rod 4; a plurality of support plates 5, each of which is hinged at the bottom of the plurality of support rods 4, and each of which can be in contact with the foundation pit ground; a plurality of fixed cones 6, each of which is fixed at the bottom of the plurality of support plates 5, and each of which can be inserted into the underground in the foundation pit; two support assemblies, each of which is arranged between the plurality of steel sheet pile bodies 1, and is used to support and isolate the steel sheet pile body 1.

[0022] In this embodiment, the steel sheet pile body 1 serves as the main load-bearing part of the cofferdam structure. These steel sheet piles are closely arranged and in contact with the inner wall of the foundation pit, effectively bearing the external soil pressure or water pressure. The linkage device on their edges allows the steel sheet piles to be freely combined to form a continuous and tight retaining wall or water retaining wall, thereby enhancing the stability of the overall structure. The clamping plate 2 is designed to be U-shaped and can be clamped on the other side of the adjacent steel sheet pile body 1. This design not only simplifies the connection process between the steel sheet piles, but also improves the stability of the connection, ensuring that the integrity of the cofferdam structure is not affected. The design of the support shaft 3 and the support rod 4 allows the support rod 4 to adjust its angle as needed to adapt to different foundation pit terrains and support requirements. The support plate 5 and the fixing cone 6 can be placed stably on the foundation pit ground, providing additional support for the cofferdam structure. The fixing cone 6 is fixed to the bottom of the support plate 5 and can be inserted into the ground, effectively preventing the support plate 5 from displacing when subjected to force, thereby enhancing the stability of the support device.

[0023] In a further preferred embodiment of the present invention, the support assembly includes two limit blocks 8, two hydraulic rods 9 and a support rod 10, and the limit cylinder 7 is installed on the side where the multiple steel sheet pile bodies 1 are close to each other. The two limit blocks 8 are movably installed in the two limit cylinders 7 respectively, and the two hydraulic rods 9 are respectively fixed on the side where the two limit blocks 8 are close to each other. The support rod 10 is fixed between the two hydraulic rods 9 and fixedly connected to the output rods of the two hydraulic rods 9.

[0024] In this embodiment, the design of the limit block 8 enables the support assembly to be accurately positioned between the steel sheet piles, ensuring the accurate transmission of the support force. At the same time, the mobility of the limit block 8 in the limit cylinder 7 also provides a certain flexibility for the adjustment of the support assembly. The hydraulic rod 9 serves as the main power source of the support assembly and can adjust the length of its output rod as needed, thereby controlling the length of the support rod 10 and facilitating the assembly and disassembly of the support rod 10. The support rod 10, as the core component of the support assembly, directly bears the pressure from the outside of the foundation pit and transmits it to the steel sheet pile body 1 and the supporting structure.

[0025] In a further preferred embodiment of the present invention, a plurality of the hydraulic rods 9 are provided with a support assembly, and the support assembly includes a fixed plate 11, a threaded barrel 12, a threaded rod 13, a bottom rod 14 and a universal wheel 15. The fixed plate 11 is fixedly sleeved on the outside of any one of the hydraulic rods 9, the threaded barrel 12 is installed at the bottom of the fixed plate 11, the threaded rod 13 is threadedly installed in the threaded barrel 12, the bottom rod 14 is installed at the bottom of the threaded rod 13, and the universal wheel 15 is installed at the bottom of the bottom rod 14. The universal wheel 15 can contact the ground in the foundation pit.

[0026] In this embodiment, the fixed plate 11 serves as a connecting component between the support assembly and the hydraulic rod 9, and the threaded barrel 12 provides a track for the installation and adjustment of the threaded rod 13. The connection between the threaded barrel 12 and the fixed plate 11 is firm and reliable to withstand the pressure from the support assembly. The bottom rod 14 serves as a connecting component between the support assembly and the universal wheel 15, which can ensure the stability of the support assembly. The design of the universal wheel 15 enables the support device to be easily moved and adjusted when needed, thereby improving the flexibility and convenience of construction.

[0027] In a further preferred embodiment of the present invention, a plurality of the universal wheels 15 are provided with a self-locking structure, and a plurality of the universal wheels 15 are fixedly covered with an anti-slip rubber sleeve.

[0028] In this embodiment, the self-locking structure is a device that can lock the rotation direction of the universal wheel 15. When the position of the support device needs to be fixed, the universal wheel 15 can be locked by the self-locking structure to prevent it from continuing to roll, so as to stabilize the support assembly subsequently. The anti-slip rubber sleeve is made of a material with a high friction coefficient, which can increase the friction between the universal wheel 15 and the foundation pit ground to prevent sliding or rollover during movement.

[0029] In a further preferred embodiment of the present invention, the plurality of steel sheet pile bodies 1 are all wavy, and the side of the plurality of steel sheet pile bodies 1 close to the support shaft 3 is installed with a limiting plate that can contact the ground in the foundation pit, and the angles between the plurality of limiting plates and the plurality of steel sheet pile bodies 1 are all 90°.

[0030] In this embodiment, the wavy steel sheet pile body 1 not only increases the rigidity of the steel sheet pile, making it more resistant to pressure from the outside of the foundation pit, but also increases the friction between the steel sheet pile and the foundation pit soil, which helps to prevent the support structure from slipping. When the wavy steel sheet pile is subjected to pressure, its wave shape can disperse stress and reduce the phenomenon of local stress concentration, thereby extending the service life of the steel sheet pile. The limit plate provides additional support for the support device. The design of the limit plate not only enhances the overall stability of the support device, but also limits the lateral movement of the steel sheet pile when under pressure, thereby preventing damage to the support structure.

[0031] In a further preferred embodiment of the present invention, the support rod 10 is composed of two fixed rods and a connecting rod. The two fixed rods are respectively installed on the output rods of any two hydraulic rods 9, and the connecting rod is welded between the two fixed rods.

[0032] In this embodiment, the connecting rod is welded between the two fixed rods, connecting the two fixed rods into a whole, so that connecting rods of different lengths can be selected according to the specifications of the foundation pit, increasing the flexibility of the device and the scope of use of the hydraulic rod 9. Compared with directly replacing the support component body, it saves more resources. The support rod 10 of the combined structure can be flexibly adjusted according to the actual situation of the foundation pit, thereby reducing production costs and material waste.

[0033] In a further preferred embodiment of the present invention, multiple support plates 5 are threadedly installed with fixing bolts, and multiple fixing bolts can be threadedly connected to multiple steel sheet pile bodies 1 respectively, and isolation plates that can contact the ground are installed on the tops of multiple steel sheet pile bodies 1, and warning light strips are provided on multiple isolation plates.

[0034] In this embodiment, the fixing bolts connect the steel sheet pile body 1 with the support plate 5, which facilitates the installation of the steel sheet pile body 1 and prevents the support plate 5 from shaking and affecting the process of its insertion into the ground. The isolation plate is designed to prevent the top edge of the steel sheet pile body 1 from cutting people. The warning light bar can emit a striking light signal to remind people around to pay attention to the existence and danger of the foundation pit. This design is particularly important at night or under poor visibility conditions. It can effectively prevent people from mistakenly entering the foundation pit area and reduce the occurrence of safety accidents.

[0035] In summary, compared with the relevant technology, the present device can increase the tightness of the connection between the single-row steel sheet pile bodies 1 by setting the clamping plate 2, and can isolate the two relative steel sheet pile bodies 1 by setting the support assembly to prevent them from being unstable and collapsing in the direction of approaching each other, and can support the support assembly by setting the support assembly to increase the convenience of moving and installing the support assembly, and can further limit the angle of the steel sheet pile body 1 by setting the support rod 4 in conjunction with the support plate 5 and the fixed cone 6 to prevent it from tilting and collapsing.
