Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a waler support structure and foundation pit support system. Background Technology

[0002] Foundation pit support construction is a crucial part of engineering construction. It mainly refers to a series of support measures taken after the foundation pit is excavated to prevent the collapse of the soil on the side wall of the foundation pit, ensure construction safety, and maintain the stability of the surrounding environment.

[0003] In existing technologies, most walers are supported by welding triangular support plates. However, in the construction of support structures in long and narrow foundation pits, segmented construction is required. This process necessitates a large number of welding operations for the triangular support plates. The excessive number of welding operations results in a large amount of welding work on the construction site, reducing construction efficiency. Furthermore, the removal of the welded triangular support plates after construction also leads to significant losses.

[0004] Therefore, it is necessary to provide a waler support structure and a foundation pit support system to solve the above-mentioned problems existing in the prior art. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a waler support structure and foundation pit support system to solve the technical problem that the welding of triangular support plates in the prior art results in a large amount of welding work on the construction site and reduced construction efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a waler support structure for supporting walers on sheet piles, the waler support structure comprising:

[0007] The first hook, the hook head of the first hook is used to suspend the steel sheet pile;

[0008] The pendant has one end connected to the hook tail of the first hook;

[0009] The second hook has its tail connected to the other end of the hanging piece, and its head is used to connect to the waler.

[0010] The waler support structure provided by this utility model has the following beneficial effects:

[0011] The waler support structure is assembled by connecting one end of the hanger to the hook tail of the first hook and the other end to the hook tail of the second hook. After the sheet pile driving is completed, when assembling the waler, the hook head of the first hook is suspended on the sheet pile, so that the waler support structure has a stable anchor point. The hook head of the second hook is connected to the waler, and the waler is supported on the sheet pile by the tension of the waler support structure, thereby connecting the waler to the sheet pile. Compared with the existing technology that uses welded triangular support plates to support the waler, the waler support structure of this utility model can not only effectively reduce the amount of welding on the foundation pit support construction site and improve construction efficiency in the long foundation pit construction environment, but also reduce the material consumption caused by welding and save production costs.

[0012] Furthermore, it also includes a connector, one end of which is connected to the hook head of the second hook, and the other end is fixedly connected to the waler. Its advantage lies in that by designing a connector between the second hook and the waler, the waler support structure and the waler can be more securely fixed and installed, avoiding significant displacement of the waler during construction.

[0013] Furthermore, it also includes fasteners, with a through hole at the other end of the connector, through which the fastener passes to fix the connector to the waler. The advantages are: by using the fasteners and through holes to fix the connector and waler, the waler support structure and the waler are fixedly installed, making assembly and disassembly more convenient, and allowing for repeated use.

[0014] Furthermore, the connector is a third hook. Its advantages are: by using a third hook as the connector, the structure is simple and easy to assemble and disassemble.

[0015] Furthermore, the hanging component is an integrated hanging rod, with one end connected to the hook end of the first hook and the other end connected to the hook end of the second hook. Its advantage lies in that by using an integrated hanging rod as the hanging component, its overall integrity allows it to better withstand tensile forces.

[0016] Furthermore, the hanging component is a hanging chain, with one end connected to the hook end of the first hook and the other end connected to the hook end of the second hook. Its advantage lies in the fact that by selecting a hanging chain, its segmented nature allows for flexible adjustment of the length according to actual construction needs.

[0017] To solve the above-mentioned technical problems, this utility model also provides a foundation pit support system, comprising:

[0018] Steel sheet piles;

[0019] Rafters;

[0020] As described above, the first hook of the waler support structure is suspended from the notch of the sheet pile, and the second hook of the waler support structure is connected to the waler to support the waler on the sheet pile.

[0021] Furthermore, the sheet pile includes a first connecting plate, a second connecting plate, and a folded edge plate. The two second connecting plates are respectively connected to both sides of the first connecting plate to form a notch in the sheet pile. The two folded edge plates are respectively connected to the two second connecting plates.

[0022] Furthermore, the waler is provided with fastening holes.

[0023] Furthermore, it also includes a steel support member, which is fixedly installed with the waler.

[0024] The beneficial effects of the foundation pit support system provided by this utility model are the same as those of the waler support structure described above. Attached Figure Description

[0034] like Figures 1-3As shown, an embodiment of this utility model provides a waler support structure for supporting a waler 30 on a sheet pile 20. The waler support structure 10 includes: a first hook 1, a hanger 2, and a second hook 3. The hook head of the first hook 1 is used to suspend the sheet pile 20. One end of the hanger 2 is connected to the hook tail of the first hook 1. The hook tail of the second hook 3 is connected to the other end of the hanger 2, and the hook head of the second hook 3 is used to connect to the waler 30.

[0035] By connecting one end of the hanger 2 to the hook tail of the first hook 1 and the other end to the hook tail of the second hook 3, the waler support structure 10 is assembled. After the sheet pile 20 is driven into the ground, when assembling the waler 30, the hook head of the first hook 1 is suspended on the sheet pile 20, so that the waler support structure 10 has a stable anchor point. The hook head of the second hook 3 is connected to the waler 30. The waler support structure 10 supports the waler 30 on the sheet pile 20 through the tension of the waler support structure 10, thereby connecting the waler 30 and the sheet pile 20. Compared with the existing technology that uses welded triangular support plates to support the waler 30, the waler support structure 10 of this utility model can not only effectively reduce the amount of welding on the construction site and improve the on-site construction efficiency in the long foundation pit construction environment, but also reduce the material consumption caused by welding and save production costs.

[0036] Specifically, during the construction of the waler 30, the hook head of the second hook 3 passes through the corresponding hole of the waler 30. The waler 30 is suspended and supported on the steel sheet pile 20 by the tension generated by the second hook 3, the hanger 2 and the first hook 1, thereby connecting the waler 30 and the steel sheet pile 20 without welding. When disassembling, only the hook head of the second hook 3 needs to be removed. It can be reused. Compared with the existing welding method, disassembly and assembly are more convenient and faster, and construction costs are saved.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the waler support structure 10 further includes a connector 4. One end of the connector 4 is connected to the hook head of the second hook 3, and the other end is fixedly connected to the waler 30. In this embodiment, the connector 4 is designed between the waler 30 and the second hook 3, which can more firmly fix the waler support structure 10 and the waler 30 together, providing support for the waler 30, thereby making the waler 30 fit more tightly against each sheet pile 20 and bear the construction load.

[0038] like Figure 1 and Figure 2As shown, in some embodiments of this utility model, the waler support structure 10 further includes a fastener 5. The other end of the connector 5 has a through hole, through which the fastener 5 passes to fix the connector 4 to the waler 30. In this example, the connector 4 and the waler 30 are fixedly connected together by the fastener 5 and the through hole, that is, the waler support structure 10 and the waler 30 are fixedly connected together, preventing the waler 30 from shifting significantly during construction, and more securely connecting the waler 30 and the sheet pile 20, thereby enabling the waler 30 to better withstand construction loads. Exemplarily, the fastener 5 is a bolt.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the connector 4 is a third hook. In this embodiment, the hook head of the third hook is suspended from the hook head of the second hook 3. A through hole is opened at the hook tail of the third hook, and the fastener 5 passes through the through hole of the third hook to fix the third hook to the waler 30 together. The waler 30 is supported on the steel sheet pile 20 by the tension of the waler support structure 10.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the hanging member 2 is an integrated hanging rod. One end of the hanging rod is connected to the hook tail of the first hook 1, and the other end is connected to the hook tail of the second hook 3. In this embodiment, the hanging member 2 located between the first hook 1 and the second hook 3 adopts an integrated hanging rod. Based on the continuity and integrity of the integrated design, it can better withstand the tensile force and more evenly transfer the load to the first hook 1, and it is convenient for construction personnel to assemble the integrated hanging rod with the first hook 1 and the second hook 3 on the construction site. Exemplarily, the hook tails of the first hook 1 and the second hook 3 are both provided with first bolt holes, and both ends of the hanging rod are provided with second bolt holes corresponding to the first bolt holes. By inserting bolts into the first bolt holes and the second bolt holes and cooperating with nuts, the hanging rod and the first hook 1 and the second hook 3 are fixedly connected, completing the assembly of the waler support structure 10.

[0041] In some embodiments of this utility model, the hanging element 2 is a hanging chain. One end of the hanging chain is connected to the hook end of the first hook 1, and the other end is connected to the hook end of the second hook 3. In this embodiment, the hanging chain is used as the hanging element 2. Based on the segmented nature of the hanging chain, the length can be flexibly adjusted according to actual construction needs. The tension generated by the cooperation of the first hook 1, the hanging chain, and the second hook 3 supports the waler 30 on the sheet pile 20. Furthermore, during construction, the hanging chain can evenly distribute the construction load to the first hook 1 and the second hook 3 at both ends of the hanging chain, reducing the risk of damage caused by local overload. Exemplarily, both ends of the hanging chain are fixedly connected to the first hook 1 and the second hook 3 by spring buckles.

[0042] like Figures 1-3 As shown, an embodiment of this utility model also provides a foundation pit support system, including: the aforementioned waler support structure 10, sheet piles 20, and walers 30. The waler support structure 10 is used to support the walers 30 on the sheet piles 20. Specifically, the first hook 1 of the waler support structure 10 is suspended from the recess 24 of the sheet pile 20, and the second hook 3 of the waler support structure 10 is connected to the walers 30 to support the walers 30 on the sheet piles 20. It should be understood that the sheet piles 20 are an important component of the foundation pit support system; they are inserted into the ground and serve to block the lateral pressure of the soil. The walers 30 are horizontal members in the foundation pit support system used to support the top of the sheet piles; they bear the loads from the top of the foundation pit, such as construction loads and lateral soil pressure. Exemplarily, the walers 30 are made of H-beams, which can withstand larger loads.

[0043] For example, the construction steps of the foundation pit support system are as follows: The waler support structure 10 is assembled, specifically by fixing both ends of the integrated hanging rod (using an integrated hanging rod as an example) to the hook tails of the first hook 1 and the second hook 3 respectively using bolts and nuts; the connecting piece 4, for example, the hook head of the third hook, is suspended from the hook head of the second hook 3. The sheet piles 20 are driven, and the hook tail of the third hook is fixedly connected to the waler 30 using fasteners 5, thereby supporting the waler 30 through the tension of the waler support structure 10. By designing the waler support structure 10 to replace the traditional welded triangular support plate method, the waler 30 can be quickly installed on the sheet piles 40 in long and narrow foundation pit construction environments. Furthermore, it can be quickly disassembled without cutting after construction, and the waler support structure 10 can be reused, avoiding material waste.

[0044] like Figure 3As shown, in some embodiments of this utility model, the sheet pile 20 includes a first connecting plate 21, a second connecting plate 22, and a folded edge plate 23. Two second connecting plates 22 are respectively connected to both sides of the first connecting plate 21 to form a notch 24 in the sheet pile 20. Two folded edge plates 23 are respectively connected to the two second connecting plates 22. In this embodiment, when driving the sheet pile 20, a pile driver is used to drive the first connecting plate 21 of the first sheet pile 20 towards the foundation pit, and the first connecting plate 21 of the second sheet pile 20 away from the foundation pit, with the folded edge plate 23 of the second sheet pile 20 engaging with the folded edge plate 23 of the first sheet pile 20, and so on, driving multiple sheet piles 20 according to construction requirements. The first hook 1 of the waler support structure 10 is suspended from the notch 24 of the sheet pile 20. Based on the original foundation pit support structure, an innovative design is carried out, which effectively solves the technical problem that the welding of triangular support plates in the existing technology leads to a large amount of welding work on the construction site and reduces construction efficiency. The overall structure is simple and convenient and quick to assemble and disassemble in the actual construction environment.

[0045] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the waler 30 has fastening holes. In this embodiment, the fasteners 5 of the waler support structure 10 pass through the through holes of the connector 4 and the fastening holes of the waler 30 respectively, to fix the connector 4 and the waler 30 together, thereby fixing the waler support structure 10 and the waler 30 together, so that the waler support structure 10 provides support force to the waler 30, and tightly fits the waler 30 onto the sheet pile 20. Through the suspended waler support structure 10 of this utility model, when the waler 30 is subjected to construction loads, the load can be evenly distributed on the sheet pile 20 through the connection of the connector 4, the second hook 3, the hanger 2, and the first hook 1, thereby improving the overall stability of the foundation pit support system.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the foundation pit support system further includes a rigid support member 40. The steel support member 40 is fixedly installed with the waler 30. Specifically, a steel support member 40 is erected on both sides of the waler 30, that is, the steel support member 40 spans both sides of the foundation pit and is fixedly installed with the waler 30. Exemplarily, the steel support member 40 and the waler 30 are locked together by bolts and nuts. It should be understood that the rigid support member 40, through its own rigidity and strength, can effectively resist the lateral earth pressure generated by the soil of the foundation pit sidewall, preventing soil collapse; and it connects the waler 30, the sheet pile 20, and the waler support structure 10 into a whole, improving the overall stability of the foundation pit support system.

[0047] In summary, addressing the technical problem of high welding workload and reduced construction efficiency caused by the welding of triangular support plates in existing technologies, this utility model provides a waler support structure and foundation pit support system. By replacing the traditional welding of triangular support plates with a simple suspended waler support structure, the amount of welding on-site can be effectively reduced, greatly improving construction efficiency. Furthermore, it can be reused after dismantling, reducing welding losses and saving construction costs. Specifically, the waler support structure is assembled by connecting one end of the hanger to the hook tail of the first hook and the other end to the hook tail of the second hook. The hook head of the first hook is suspended from the sheet pile, and the hook head of the second hook is connected to the waler. After the sheet pile driving is completed, during the assembly of the waler, the hook of the first hook is suspended from the sheet pile, providing a stable anchor point for the entire waler support structure. The hook of the second hook is connected to the waler, and the waler is supported by the tension of the waler support structure on the sheet pile, thus connecting the waler to the sheet pile. Compared with the existing technology that uses welded triangular support plates to support the waler, the waler support structure of this invention does not require extensive welding in long foundation pit construction environments, facilitating on-site installation and disassembly, and greatly improving the convenience of on-site construction. Furthermore, one end of the connector is detachably connected to the hook of the second hook, while the other end is fixedly connected to the waler, making the waler support structure more securely fixed to the waler and facilitating disassembly and installation. Therefore, this invention effectively overcomes the various shortcomings of the existing technology and has high industrial application value.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
