Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering construction technology, and in particular to a waler reinforcement structure and a foundation pit support system. Background Technology
[0002] In the field of construction, safety and structural stability are paramount. They are not only essential for the successful completion of the project but also the cornerstone for protecting the lives of construction workers. Among the many construction stages, foundation pit engineering is particularly critical, as it relates not only to the stability of the entire building but also directly involves the safety of construction personnel. The safety of foundation pit engineering is the cornerstone of the success of the entire construction project; any negligence in this stage can lead to serious consequences.
[0003] To ensure the safety of foundation pits, existing foundation pit support technologies typically employ multiple supports to reinforce the walers. However, excessive supports can severely impact excavation efficiency and construction progress. Conversely, insufficient supports may lead to inadequate support strength, creating safety hazards. Therefore, there is an urgent need for a waler reinforcement structure that can provide sufficient support strength without increasing the number of supports, ensuring the stability of the foundation pit and the safety of construction workers. Utility Model Content
[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a waler reinforcement structure and a foundation pit support system, so as to solve the problem that the excessively dense support components in the foundation pit support of the prior art affect the excavation efficiency and structural construction progress of the foundation pit.
[0005] To solve the above-mentioned technical problems, this utility model provides a waler reinforcement structure for providing support for multiple retaining walls in a foundation pit, comprising:
[0006] A waler frame, comprising multiple walers adapted to the dimensions of the retaining wall, wherein one side of each of the multiple walers is fixed to a corresponding retaining wall, and the multiple walers together form a waler frame adapted to the outline of the foundation pit.
[0007] Multiple reinforcing walers corresponding to the multiple walers, wherein one side of each reinforcing waler is fixed to the other side of the corresponding waler;
[0008] Multiple tie rod structures corresponding to the multiple reinforcing walers, with both ends of each tie rod structure fixed to one side of the reinforcing waler, and each tie rod structure applying a prestress to both ends of the reinforcing waler toward the center of the tie rod structure.
[0009] As a more preferred approach, the reinforcing waler is positioned at the center of the other side of the waler. When the waler bears the load from the supporting wall, the stress at the center of the waler is the greatest. By using the reinforcing waler, the stress-bearing capacity of this area can be enhanced. At the same time, the tie rod structure installed on the reinforcing waler can apply prestress to the reinforcing waler to balance the stress generated by the load from the supporting wall in this area.
[0010] As a more preferred embodiment, the tie rod structure includes a tie rod and two connectors, the two connectors being fixed to both ends of the reinforcing waler, the two ends of the tie rod being fixed to the connectors, and the connectors applying a pulling force toward both ends of the tie rod.
[0011] As a more preferred embodiment, the connector includes two fixing plates and a connecting plate perpendicular to the two fixing plates. The fixing plates and the connecting plates are fixed to the reinforcing waler. The connecting plate is provided with a connecting hole, and one end of the pull rod passes through the connecting hole.
[0012] As a more preferred embodiment, the waler includes two support plates and multiple horizontal plates. The two ends of the horizontal plates are respectively fixed perpendicularly to the opposite sides of the two support plates. The horizontal plates are used to strengthen the waler structure. When bearing loads from the supporting wall, the evenly arranged side plates ensure that the stress on each part of the waler is uniform.
[0013] As a more preferred approach, the waler reinforcement structure also includes multiple corner braces, which are positioned at the top of the included angle between adjacent walers. These corner braces further enhance the load-bearing capacity of the waler reinforcement structure and improve its structural stability.
[0014] As a more preferred embodiment, the corner brace includes two side plates and a reinforcing plate connecting the side plates, wherein the angle between the two side plates is the same as the included angle between the corresponding adjacent walers, and when the corner brace is set at the top of the corresponding included angle, the two side plates are respectively attached to the corresponding walers.
[0015] As a more preferred approach, the waler reinforcement structure also includes multiple support rods, the two ends of which are respectively connected to the adjacent walers.
[0016] As a more preferred approach, the waler frame also includes multiple corner connectors. Adjacent walers are connected by corner connectors, and the angle between adjacent walers is adjusted by the corner connectors to adapt to the angle between adjacent support walls, thereby ensuring that the connection between walers can be achieved even when facing irregular foundation pits.
[0017] To address the aforementioned problems, this utility model also provides a foundation pit support system, comprising: the aforementioned waler reinforcement structure.
[0018] As described above, the waler reinforcement structure and foundation pit support system of this utility model have the following beneficial effects: When the waler reinforcement structure of this utility model is used in a foundation pit, it strengthens the waler frame by reinforcing the waler, enabling it to withstand greater loads from the supporting wall. Simultaneously, a prestress is applied to both ends of the reinforced waler towards the center of the tie rod structure using a tie rod structure. This prestress causes the reinforced waler to bulge outwards towards the foundation pit. When the waler reinforcement structure bears the load of the supporting wall, the waler experiences a stress that causes it to concave inwards towards the foundation pit. This stress is transmitted to the reinforced waler, and under the action of the prestress of the tie rod structure, the reinforced waler counteracts the stress generated by the load of the supporting wall, thereby improving the load-bearing capacity of the waler reinforcement structure for the supporting wall. Furthermore, since both the reinforced waler and the tie rod structure are directly attached to the waler, they do not occupy space within the frame, ensuring sufficient space for foundation pit excavation and structural construction, thus improving efficiency.
[0019] The foundation pit support system of this utility model adopts the above-mentioned waler reinforcement structure. The reinforced waler strengthens the structure of the waler frame, and the prestress of the tie rod structure is used to balance the load of the support wall. Without occupying the internal space of the foundation pit, the support capacity of the foundation pit support system is improved, and the stability and safety are enhanced.
[0020] In summary, the waler reinforcement structure and foundation pit support system of this utility model improve the structural strength while saving foundation pit space by strengthening the waler and tie rod structure, and solves the problem that the excessively dense support components in the existing foundation pit support technology affect the excavation efficiency and structural construction progress of the foundation pit.

[0046] like Figure 1 as well as Figure 3 As shown, this utility model provides a waler reinforcement structure for providing support for multiple retaining walls in a foundation pit, comprising:
[0047] The waler frame 1 includes a plurality of walers 11 adapted to the size of the support wall. One side of each of the plurality of walers 11 is fixed to the corresponding support wall, and the plurality of walers 11 together form a waler frame 1 adapted to the outline of the foundation pit.
[0048] A plurality of reinforcing walers 2 corresponding to the plurality of walers 11, wherein one side of the reinforcing waler 2 is fixed to the other side of the corresponding waler 11;
[0049] Multiple tie rod structures 3 are provided corresponding to the multiple reinforcing walers 2. The two ends of each tie rod structure 3 are fixed to one side of the reinforcing waler 2. Each tie rod structure 3 applies a prestress to both ends of the reinforcing waler 2 towards the center of the tie rod structure 3.
[0050] To better illustrate the waler reinforcement structure of this utility model, the following specific application will be used as an example: When used in a foundation pit, the waler reinforcement structure of this utility model strengthens the waler frame 1 by reinforcing the waler 2, enabling it to withstand greater loads from the supporting wall. Simultaneously, using the tie rod structure 3, a prestress is applied to both ends of the reinforced waler 2 towards the center of the tie rod structure 3. This prestress generates a tendency for the reinforced waler 2 to bulge outwards from the foundation pit. When the waler reinforcement structure bears the load of the supporting wall... When subjected to a load, the waler 11 is subjected to stress that causes it to concave inward toward the foundation pit. This stress is transmitted to the reinforcing waler 2. Under the prestress of the tie rod structure 3, the reinforcing waler 2 counteracts the stress generated by the load on the retaining wall, thereby improving the load-bearing capacity of the reinforcing waler structure for the retaining wall. At the same time, since both the reinforcing waler 2 and the tie rod structure 3 are directly attached to the waler 11, they do not need to occupy the space inside the frame, ensuring space for foundation pit excavation and structural construction, and improving efficiency.
[0051] In some possible embodiments of this utility model, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the reinforcing waler 2 is located at the center of the other side of the waler 11. When the waler 11 bears the load from the retaining wall, the stress at the center of the waler 11 is the greatest. By using the reinforcing waler 2, the stress bearing capacity of this area can be enhanced. At the same time, the tie rod structure 3 installed on the reinforcing waler 2 can apply prestress to the reinforcing waler 2 to balance the stress generated by the load of the retaining wall in this area.
[0052] In some possible embodiments of this utility model, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the tie rod structure 3 includes a tie rod 31 and two connecting members 32. The two connecting members 32 are respectively fixed to both ends of the reinforcing waler 2. The two ends of the tie rod 31 are respectively fixed to the connecting members 32. The connecting members 32 respectively apply a tensile force to the tie rod 31 towards its two ends. Furthermore, in this embodiment, the tie rod 31 is made of steel. Steel has very high tensile strength and can withstand heavy loads, making it very suitable for use as a tie rod 31, especially in the waler 11 support structure.
[0053] In some possible embodiments of this utility model, such as Figure 1 , Figure 2 as well as Figure 3As shown, the connector 32 includes two fixing plates 321 and a connecting plate 322 that is perpendicular to the two fixing plates 321 respectively.

The connecting plate 322 is provided with a connecting hole, and one end of the pull rod 31 passes through the connecting hole.
[0054] In some possible embodiments of this utility model, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the waler 11 includes two support plates 111 and multiple horizontal plates 112. The two ends of each horizontal plate 112 are perpendicularly fixed to the opposite sides of the two support plates 111, and the horizontal plates 112 are used to reinforce the waler 11 structure. The side plates 41 are parallel to each other and spaced at equal intervals. When bearing loads from the retaining wall, the evenly distributed side plates 41 ensure uniform stress distribution on the waler 11. Similarly, the reinforced waler 2 includes two reinforcing support plates 21 and multiple reinforcing horizontal plates. 22, the two ends of the reinforcing horizontal plate 22 are respectively fixed perpendicularly to the opposite sides of the two reinforcing support plates 21, and the reinforcing horizontal plate 22 is used to strengthen the reinforcing waler 2 structure; the reinforcing side plates 41 are parallel to each other and spaced at the same distance. When bearing the load from the supporting wall, the evenly arranged side plates 41 ensure that the force on the reinforcing waler 2 is uniform; furthermore, a plurality of weight-reducing holes 112a are evenly opened on the support plate 111, which saves materials and reduces the weight while meeting the structural strength requirements.
[0055] In some possible embodiments of this utility model, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the waler reinforcement structure also includes multiple corner braces 4, which are located at the top of the included angle between adjacent walers 11. The corner braces 4 further enhance the load-bearing capacity of the waler reinforcement structure and improve the structural stability.
[0056] In some possible embodiments of this utility model, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the corner brace 4 includes two side plates 41 and a reinforcing plate 42 connecting the side plates 41. The angle between the two side plates 41 is the same as the included angle between the corresponding adjacent walers 11. When the corner brace 4 is set at the top of the corresponding included angle, the two side plates 41 are respectively attached to the corresponding walers 11.
[0057] In some possible embodiments of this utility model, such as Figure 1 , Figure 2 as well as Figure 3As shown, the waler reinforcement structure also includes multiple support rods 5, with both ends of the support rods 5 connected to the adjacent walers 11.

Adjacent walers 11 are connected by corner connectors 32. The angle between adjacent walers 11 can be adjusted by the corner connectors 32 to adapt to the angle between adjacent support walls, thereby ensuring that the connection between walers 11 can be achieved even when facing irregular foundation pits.
[0059] More specifically, in some possible embodiments of this utility model, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the foundation pit includes four mutually perpendicular support walls, and the waler frame 1 includes four walers 11. The four walers 11 are horizontally set on the corresponding support walls, and the four walers 11 are connected end to end vertically to form a waler frame 1 that matches the outline of the foundation pit. The waler reinforcement structure also includes four reinforcing walers 2 and four tie rod structures 3 set on the reinforcing walers 2. Furthermore, the waler reinforcement structure also includes four corner braces 4, the two side plates 41 of the corner braces 4 are mutually perpendicular and are used to match the corresponding walers 11.

This improves the support capacity of the foundation pit support system without occupying the internal space of the foundation pit, thereby enhancing stability and safety. It can be seen that the waler reinforcement structure and foundation pit support system of this utility model, by strengthening the waler 2 and the tie rod structure 3, improve the structural strength while saving foundation pit space, solving the problem that excessively dense support components in existing foundation pit support technologies affect the excavation efficiency and structural construction progress of the foundation pit.
