Description
Technical Field
[0001] This application relates to the field of trench construction, specifically to a temporary passage device for trenches. Background Technology
[0002] When excavating municipal trenches, if the trench construction encounters a residential area entrance or intersection, it is often necessary to temporarily divert traffic and then carry out the work in sections.
[0003] While segmented trenching can ensure project progress, it is often unsuitable in certain special circumstances. For example, in areas with narrow roads where traffic cannot be interrupted, trench excavation may force temporary traffic disruptions. For projects with tight deadlines, segmented construction will inevitably delay the project schedule.
[0004] Therefore, this application proposes a temporary passage device for trenches, which aims to ensure safe construction while also accommodating traffic flow. Summary of the Invention
[0005] This application provides a temporary passage device for trenches, which can solve the technical problem in the prior art where traffic has to be temporarily interrupted after trench excavation.
[0006] In a first aspect, embodiments of this application provide a temporary passage device for a trench, comprising: two support structures, each supported on one of the inner walls of the trench, wherein the inner walls of the support structures are provided with horizontal waist beams along the direction of the trench; a frame beam, comprising multiple parallel main beams and multiple parallel secondary beams, wherein the two ends of the main beams are respectively provided on the waist beams of the two support structures, and the secondary beams are provided on the top of the main beams, forming a mesh structure perpendicular to each other; and a top plate, which is laid on the top of the secondary beams.
[0007] In conjunction with the first aspect, in some embodiments, the support structure includes a plurality of sheet piles inserted into the bottom of the trench, adjacent sheet piles being interlocked with each other, and the sheet piles being in close contact with the inner wall of the trench, and the waist beam being disposed on the inner wall of the sheet piles.
[0008] In conjunction with the first aspect, in some embodiments, the sheet piles are Larssen steel sheet piles.
[0009] In conjunction with the first aspect, in some embodiments, the inner wall of the support structure is provided with a waist beam bracket, and the waist beam is set on the inner wall of the sheet pile through the waist beam bracket.
[0010] In conjunction with the first aspect, in some embodiments, the waist beam bracket is provided with a limiting member to prevent the waist beam from sliding towards the center of the groove.
[0011] In conjunction with the first aspect, in some embodiments, the limiting member is a round tube with its two ends respectively disposed on the waist beam brackets of the two support structures and abutting against the inner sidewall of the waist beam.
[0012] In conjunction with the first aspect, in some embodiments, the inner diameter of the circular tube is not greater than the vertical height of the waist beam.
[0013] In conjunction with the first aspect, in some embodiments, the waist beam bracket and the sheet pile are fixed together by welding.
[0014] In conjunction with the first aspect, in some embodiments, a pad is provided between the waist beam and the waist beam bracket, the main beam is disposed on the top of the waist beam, and a pad is provided between the two.
[0015] In conjunction with the first aspect, in some embodiments, the main beam, secondary beam, and web beam are all I-beams.
[0016] The beneficial effects of the technical solutions provided in this application include:
[0017] By supporting the two inner walls of the trench with two support structures respectively, the stability of the entire structure is greatly enhanced. The support structures can not only effectively prevent lateral compression of soil or water flow, but also ensure that no collapse accident occurs during passage, thereby protecting the safety of construction personnel and passing vehicles.
[0018] In addition, by setting horizontal waist beams along the trench direction on the inner sidewall of the support structure and setting the two ends of the main beam on the waist beams of the two support structures, the connection between the support structure and the frame beam is further strengthened, so that the entire device can remain stable when subjected to vertical and horizontal loads.
[0019] By placing the secondary beams on top of the main beams, forming a mutually perpendicular mesh structure, the overall rigidity of the frame beams is further enhanced, enabling them to maintain good stability under load. Simultaneously, it helps to evenly distribute external loads across the main and secondary beams, avoiding localized stress concentrations.
[0020] By laying the top plate on top of the secondary beam, a flat and stable walking surface can be provided for passersby (including but not limited to pedestrians and vehicles), and the obstacles and safety hazards caused by uneven ground can be reduced.
[0021] Furthermore, the top slab is laid on top of the secondary beams, and the load is first transferred to the secondary beams through the top slab, then from the secondary beams to the main beams, and finally from the main beams to the joists and support structure. This load transfer path ensures that the device is subjected to reasonable and efficient stress, avoiding the risk of stress concentration and localized damage. This application solves the technical problem in the prior art where traffic has to be temporarily interrupted after trench excavation. Attached Figure Description

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0035] This application provides a temporary passage device for trenches, which can solve the technical problem in the prior art where traffic has to be temporarily interrupted after trench excavation.
[0036] Reference Figures 1-4 , Figure 1 This is a schematic diagram of the trench temporary passage device in the embodiments of this application; Figure 2 for Figure 1 Sectional view along the middle AA direction; Figure 3 for Figure 1 Sectional view along the BB direction; Figure 4 for Figure 1 A cross-sectional view along the CC direction.
[0037] like Figure 1 As shown, in one embodiment, the temporary passage device for the trench includes two support structures 1, a frame beam 3, and a top plate 4. The two support structures 1 are respectively supported on the two inner walls of the trench. Each support structure 1 can be formed by multiple sheet piles connected together. A horizontal joist 2 is provided along the trench direction on the inner wall of each support structure 1. The frame beam 3 is positioned between the two support structures 1 via the joist 2. The top plate 4 is simultaneously positioned on top of both the support structures 1 and the frame beam 3. In this embodiment, by supporting the two support structures 1 on the two inner walls of the trench, this double-sided support method greatly enhances the stability of the entire device. In practical applications, the support structures 1 can be fixed by embedding them into the trench. The support structures 1 not only effectively prevent lateral compression from soil or water flow but also ensure that no collapse occurs during passage, thereby protecting the safety of construction personnel and passing vehicles.
[0038] In this embodiment, the wainscoting 2 further strengthens the connection between the support structure 1 and the frame beam 3, ensuring the stability of the entire device under both vertical and horizontal loads. The frame beam 3, positioned between the two support structures 1 via the wainscoting 2, forms a stable passage platform, making the passage path smoother and more stable, and significantly reducing obstacles caused by uneven ground. The top plate 4 is simultaneously placed on top of both the support structure 1 and the frame beam 3, providing an additional layer of protection for pedestrians and vehicles, ensuring their normal passage. Furthermore, the top plate 4 also protects construction workers working in the trench, providing them with a relatively dry, sheltered working environment and improving work efficiency.
[0039] like Figure 2 and Figure 3As shown, preferably, the frame beam 3 includes multiple parallel main beams 31 and multiple parallel secondary beams 32. The two ends of the main beams 31 are respectively positioned on the waist beams 2 of the two support structures 1, specifically, they can be placed on top of the waist beams 2. The secondary beams 32 are positioned on top of the main beams 31, forming a mutually perpendicular mesh structure. The top plate 4 is laid on top of the secondary beams 32. In this embodiment, the main beams 31, as the primary load-bearing components, have a higher load-bearing capacity than the secondary beams 32. The multiple main beams 31 are arranged in parallel, and the two ends of the main beams 31 are respectively positioned on top of the waist beams 2, thus enhancing the stability and load-bearing capacity of the entire structure. Secondly, as... Figure 3 As shown, a mesh structure is formed between the main beam 31 and the secondary beam 32, which further enhances the overall rigidity of the frame beam 3, enabling it to maintain good stability when bearing loads. Simultaneously, it also helps to evenly distribute external loads across the main beam 31 and the secondary beam 32, avoiding localized stress concentration.
[0040] By laying the top plate 4 on top of the secondary beam 32, it is certain that the top plate 4 provides a flat and stable walking surface for pedestrians (including but not limited to pedestrians and vehicles), and also reduces passage obstacles and safety hazards caused by uneven ground. In addition, with the top plate 4 laid on top of the secondary beam 32, the load will be first transferred to the secondary beam 32 through the top plate 4, then transferred from the secondary beam 32 to the main beam 31, and finally transferred from the main beam 31 to the lintel 2 and the support structure 1. This load transfer path ensures that the structure is subjected to reasonable and efficient stress, and avoids the risk of stress concentration and local damage.
[0041] Furthermore, in one embodiment, such as Figure 2 As shown, the support structure 1 includes multiple sheet piles 11, which are inserted into the bottom of the trench. Adjacent sheet piles 11 are interlocked and pressed against the inner wall of the trench. A wainscoting 2 is installed on the inner wall of the sheet piles 11. In this embodiment, the multiple sheet piles 11 are inserted into the bottom of the trench, which simplifies the installation process and saves construction time. The wainscoting 2, installed on the inner wall of the sheet piles 11, effectively resists lateral earth pressure and other external loads, enhancing the stability of the overall structure. The close contact between adjacent sheet piles 11 and the tightness between the sheet piles 11 and the inner wall of the trench reduces the water seepage path, further improving the waterproof performance of the support structure 1 and helping to keep the inside of the trench dry.
[0042] Furthermore, in one embodiment, the sheet pile 11 is a Larssen steel sheet pile. In this embodiment, the Larssen steel sheet pile is also called a U-shaped steel sheet pile. Using Larssen steel sheet piles to support the two inner walls of the trench is not only green and environmentally friendly, but also fast in construction, low in construction cost, and has excellent waterproof function.
[0043] Furthermore, in one embodiment, such as Figure 1As shown, the inner wall of the support structure 1 is provided with a waist beam bracket 12, and the waist beam 2 is set on the inner wall of the sheet pile 11 through the waist beam bracket 12. In this embodiment, the waist beam bracket 12 provides a stable support point for the waist beam 2, allowing the waist beam 2 to be more firmly connected to the inner wall of the sheet pile 11, thus enhancing the stability of the entire device and enabling it to better resist lateral earth pressure and other external loads. In addition, the waist beam bracket 12 simplifies the installation process of the waist beam 2, allowing construction personnel to more easily place the waist beam 2 on the waist beam bracket 12 and make necessary adjustments and fixation, which greatly shortens the construction time and improves construction efficiency. The waist beam bracket 12 also provides additional support for the waist beam 2, enhancing the load-bearing capacity of the waist beam 2. This allows the waist beam 2 to better distribute and transfer the load, improving the load-bearing capacity of the entire device.
[0044] Furthermore, in one embodiment, such as Figure 1 As shown, the waist beam bracket 12 is equipped with a limiting member 5 to prevent the waist beam 2 from sliding towards the middle of the trench. In this embodiment, by setting the limiting member 5 on the waist beam bracket 12 to prevent the waist beam 2 from sliding towards the middle of the trench, the waist beam 2 can be effectively prevented from sliding towards the middle of the trench during the stress process, thereby maintaining the overall stability of the device, ensuring project safety, and preventing accidents such as collapse caused by instability.
[0045] It should be noted that in this embodiment, the limiting member 5 can be installed on the waist beam bracket 12, that is, each waist beam bracket 12 corresponds to one limiting member 5, which can limit the waist beam 2. Of course, in order to enhance the stability of the limiting member 5, two waist beam brackets 12 located on the two side support structures 1 and in opposite positions can share a limiting member 5. The limiting member 5 can be a rod-shaped structure or a tubular structure, with both ends abutting against the waist beam 2, thereby achieving the limiting effect.
[0046] Furthermore, in one embodiment, such as Figure 1 and Figure 2 As shown, the limiting component 5 is a circular tube, with its two ends respectively installed on the waist beam brackets 12 of the two support structures 1, and abutting against the inner sidewall of the waist beam 2. In this embodiment, by adopting the above-mentioned technical solution, the limiting component 5 is a circular tube, which enables the waist beam 2 to be effectively supported and restricted during the stress process, preventing it from sliding towards the middle of the trench, enhancing the overall stability of the device, and ensuring the safety of the project. At the same time, using a circular tube for limiting facilitates installation and disassembly, simplifies the construction process, and improves construction efficiency.
[0047] Furthermore, in one embodiment, such as Figure 1 or Figure 2As shown, the inner diameter of the circular tube is no greater than the vertical height of the waist beam 2. In this embodiment, the two ends of the main beam 31 are respectively set on the waist beams 2 of the two support structures 1. This can distribute the load evenly to the waist beams 2, ensuring the stability of the entire device. The inner diameter of the circular tube is no greater than the vertical height of the waist beam 2, which can prevent the main beam 31 from pressing entirely on the top of the circular tube, thus avoiding the load being distributed to the circular tube, which could easily cause deformation of the circular tube. If the force is uneven, it can also lead to instability of the entire device.
[0048] Furthermore, in one embodiment, the lumbar beam bracket 12 and the sheet pile 11 are fixed together by welding. In this embodiment, welding is a rigid connection method that provides strong connection strength. Welding the lumbar beam bracket 12 and the sheet pile 11 ensures a very strong connection that is not easily affected by the external environment. At the same time, it helps improve the overall stability of the device and prevents safety accidents such as collapse.
[0049] Furthermore, in one embodiment, a pad 6 is provided between the waist beam 2 and the waist beam bracket 12, and the main beam 31 is located on top of the waist beam 2, with the pad 6 between them. In this embodiment, by adopting the above technical solution, the connection between the waist beam 2 and the waist beam bracket 12, and between the main beam 31 and the waist beam 2, can be ensured to be tighter and more stable. In actual construction, the pad 6, as an auxiliary connecting material, can fill the small gaps at the connection, preventing structural loosening or deformation due to loose connections. In addition, the pad 6 can also protect the structural materials such as the waist beam 2, the waist beam bracket 12, and the main beam 31 from direct wear and corrosion. As an isolation layer, the pad 6 can reduce direct contact between structural materials and extend the service life of the structure.
[0050] Furthermore, in one embodiment, the main beam 31, secondary beam 32, and web beam 2 are all H-beams. In this embodiment, the H-beam has an "I"-shaped cross-section with wide upper and lower flanges and a relatively thin web in the middle. This structural feature gives the H-beam good stability when subjected to bending moment and shear force. Its upper and lower flanges can provide a large compressive and tensile area, thereby effectively improving the beam's load-bearing capacity. Therefore, whether used as the main beam 31, secondary beam 32, or web beam 2, the H-beam can withstand large loads, ensuring the stability and safety of the structure. In addition, during the stress process, the H-beam is not prone to lateral or torsional instability and can effectively resist deformation. This stability is crucial to ensuring the stability and safety of the entire structure. H-beams have good weldability and cutability, facilitating on-site processing and installation. At the same time, the high degree of standardization of H-beams is conducive to the prefabrication and assembly construction of components. This makes the construction of structures using H-beams as the main beam 31, secondary beam 32, and web beam 2 more efficient and convenient.
