Description

Technical Field

[0001] This invention relates to retaining structures for roadbed masonry, and particularly to retaining structures for highway roadbed masonry, belonging to the technical field of retaining structures. Background Technology

[0002] Roadbed masonry is constructed by fixing a large number of regular crushed stones or blocks along the roadside, so that the masonry surface forms a sloping structure, which provides support from both sides of the road.

[0003] Masonry work on both sides of highway subgrades can utilize excavated soil while providing continuous support for the road. However, when masonry is being constructed alongside the subgrade, the resulting sloping structure with a height difference can cause debris or soil to fall during construction. This not only affects the project's progress but can also threaten the safety of construction workers. Therefore, retaining structures are often erected alongside the construction site for protection. However, existing retaining structures can only provide unidirectional support by fixing the device and simply block the soil pile. Over time, this can lead to the stress points of the device exceeding their limits, causing damage and making it unsuitable for long-term use.

[0004] Therefore, it is urgent to improve plastic injection molding equipment to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a retaining device for highway subgrade masonry, which can solve the problems of existing retaining devices, which can only provide unidirectional support by fixing the device and simply block the soil pile.

[0008] Preferably, the circulation section further includes a circulation chamber opened inside the L-shaped support base, the circulation chamber being connected and communicating with both the circulation port and the discharge port, and a blocking block for preventing soil from flowing out is slidably connected inside the discharge port.

[0009] Preferably, the L-shaped support base is connected to the height increasing plate via a connecting part, and the curved support plate is provided on one side of the height increasing plate, with every two curved support plates connected via the connecting part.

[0010] Preferably, the connecting part includes a connecting bend for connecting the outer sides of the two curved support plates, a connecting port for connecting the two curved support plates on adjacent sides, and a connecting post.

[0011] Preferably, the connecting part further includes a connection port opened on one side of the curved support plate and the height increasing plate, and a position connecting rod is fixedly connected to the side of the curved support plate and the height increasing plate away from the connection port, and the position connecting rod is inserted into the connection port.

[0012] Preferably, a double-layer support plate is provided on the side of the height-increasing plate away from the curved support plate, and a bottom support plate is provided below the double-layer support plate. The double-layer support plate is connected to both the height-increasing plate and the L-shaped support base, and the bottom support plate is used to support the L-shaped support base.

[0013] Preferably, the L-shaped support base has a support part on the side away from the unloading mechanism. The support part is used for overall fixation of the device. The support part includes an arc-shaped support frame that is fixedly connected to the height increasing plate and the double-layer support plate. The arc-shaped support frame has a support card interface inside, and there are several support card interfaces.

[0014] Preferably, the support card interface is connected to a support card connector, and a first support rod is fixedly connected to the side of the support card connector away from the support card interface.

[0015] Preferably, the L-shaped support base is fixedly connected to a second support rod via the bottom support plate, the second support rod is fixedly connected to the bottom support base, and the bottom support base is fixedly connected to the L-shaped support base.

[0016] Preferably, the bottom support base is disposed below the bottom support plate, and the bottom support base is located between the L-shaped support plate and the L-shaped support base.

[0017] This invention has at least the following beneficial effects:

[0018] 1. In this invention, by setting both sides of the curved support plate to be curved, the pressure of the curved support plate on the soil pile can be buffered at multiple angles, achieving the effect of unloading and supporting the soil pile. When the curved support plate faces pressure, the curved support plate will transmit force to multiple connecting plates behind it under the connection of the curved connecting blocks. Through the hyperboloid effect of the curved support plate itself, the force can be buffered at two different angles, so that the force transmitted to the curved connecting blocks is fully relieved and dissipated. At the same time, through the support of the aggregate connecting rod and the formation of multiple triangular support structures between the support curved column and the support straight column, the unloading mechanism can provide stable soil retention support during roadbed masonry under the support of multiple devices and the L-shaped support base.

[0019] 2. In this invention, when the worker pulls out the blocking block, the soil inside the circulation chamber can flow to the outside of the device. With the opening of the circulation port and the discharge port, the soil pile below the device can be discharged under the flow of the circulation section, which degrades the pressure on the entire device. At the same time, fixing the soil inside the circulation section can make the soil pile and the L-shaped support base form a whole, providing a stable support effect below the device and relieving the pressure of the soil pile above the device, thereby improving the flexibility of the device.

[0020] 3. In this invention, the L-shaped support base and the unloading mechanism are connected and fixed to the two unloading mechanisms, the upper and lower L-shaped support bases and the height increasing plate through the connection of the connecting port and the connecting column. The upper and lower curved support plates are fixed by the connection of multiple bolts, and the height increasing plate and the L-shaped support base are fixed by the connection of the double-layer support plate. This provides stable support when the height of the device is increased. By inserting and fixing the connecting rod on one side of the L-shaped support base, the curved support plate and the height increasing plate to the connecting port on the other side, stable support is provided when the horizontal length of the device is increased.

[0031] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0032] like Figures 1 to 8 As shown, the retaining wall device for highway subgrade masonry provided in this embodiment includes an L-shaped support base 1 and a stress-relief mechanism 2 disposed on one side of the L-shaped support base 1. The lower half of the L-shaped support base 1 is provided with a flow section 5. The stress-relief mechanism 2 includes a curved support plate 21 that is in direct contact with the soil pile and a curved connecting block 22 for providing support to the curved support plate 21. The curved support plate 21 is fixedly disposed on one side of the L-shaped support base 1. A connecting plate 23 is fixedly connected to the side of the curved connecting block 22 away from the curved support plate 21. There are several connecting plates 23. Each connecting plate 23 is simultaneously fixedly connected to a polymer connecting rod 24. The polymer connecting rod 24 is fixedly connected to a supporting straight column 26 via a supporting bent column 25. There are several supporting straight columns 26, and every two supporting bent columns 25 and supporting straight columns 26 form a group for support. The supporting straight columns 26 are fixedly connected to the L-shaped support base 1. The flow section 5 includes flow ports 52 and discharge ports 53 opened on opposite sides of the L-shaped support base 1. There are several flow ports 52 and discharge ports 53, and the flow ports 52 and the curved support plate 21 are located on the same side of the L-shaped support base 1.

[0033] In this embodiment, by setting both sides of the curved support plate 21 to be curved, the pressure of the curved support plate 21 on the soil pile can be buffered at multiple angles, achieving the effect of stress relief and support for the soil pile. When the curved support plate 21 faces pressure, it will transmit force to multiple connecting plates 23 behind it under the connection of the curved connecting block 22. Through the hyperboloid effect of the curved support plate 21 itself, the force can be buffered at two different angles, so that the force transmitted to the curved connecting block 22 is fully relieved and dissipated. At the same time, through the support of the aggregate connecting rod 24 and the formation of multiple support columns 25 and 26, multiple The triangular support structure allows the unloading mechanism 2 to provide stable soil retention support during roadbed masonry work, supported by the connection of multiple devices and the L-shaped support base 1. The openings of the flow port 52 and discharge port 53 allow the soil pile below the device to be discharged through the flow section 5, thus decomposing the pressure on the entire device. Simultaneously, the soil is fixed inside the flow section 5, making the soil pile and the L-shaped support base 1 a unified whole, providing stable support below the device. Therefore, through the unloading mechanism 2 and the flow section 5, the support effect of the retaining equipment can be improved through simple structural connections.

[0034] like Figure 7 and Figure 8 As shown, the retaining device for highway subgrade masonry provided in this embodiment includes a flow section 5 that further includes a flow chamber 51 opened inside the L-shaped support base 1. The flow chamber 51 is connected and communicates with the flow port 52 and the discharge port 53. A blocking block 54 for preventing soil from flowing out is slidably connected inside the discharge port 53.

[0035] In this embodiment, when the device is used for soil retention, the soil below flows into the flow port 52 under the flow support of multiple discharge ports 53. By setting the bottom edge of the flow chamber 51 as a downward-sloping curved surface structure, the soil flows into the discharge port 53 under its own gravity. At the same time, the blocking block 54 blocks the soil flow, causing the soil to accumulate inside the flow chamber 51, so that the soil and the L-shaped support base 1 form a whole, thereby achieving a stable support effect at the bottom of the device. When the operator pulls out the blocking block 54, the soil inside the flow chamber 51 can flow to the outside of the device, which can relieve the pressure of the soil pile on the top of the device, thereby improving the flexibility of the device.

[0036] like Figures 1 to 3As shown, the retaining wall device for highway subgrade masonry provided in this embodiment has an L-shaped support base 1 connected to a height-increasing plate 6 via a connecting part 3. A curved support plate 21 is provided on one side of the height-increasing plate 6. Every two curved support plates 21 are connected via a connecting part 3. The connecting part 3 includes a connecting curved surface 31 for connecting the outer sides of two curved support plates 21, a connecting port 32 for connecting adjacent sides of two curved support plates 21, and a connecting post 33. The connecting curved surface 31 connects to both the upper and lower curved support plates 21 simultaneously. The connecting port 32 is located at both the upper and lower ends of the curved support plate 21. The connecting post 33... The connecting part 3 is slidably connected to the connecting port 32. The connecting part 3 also includes a connecting port 34 opened on one side of the curved support plate 21 and the height increasing plate 6. A position connecting rod 35 is fixedly connected to the side of the curved support plate 21 and the height increasing plate 6 away from the connecting port 34. The position connecting rod 35 is inserted into the connecting port 34. A double-layer support plate 37 is provided on the side of the height increasing plate 6 away from the curved support plate 21. A bottom support plate 36 is provided below the double-layer support plate 37. The double-layer support plate 37 is connected to both the height increasing plate 6 and the L-shaped support base 1. The bottom support plate 36 is used to support the L-shaped support base 1.

[0037] In this embodiment, when the device needs to be increased in both the horizontal and vertical directions, multiple L-shaped support bases 1 and unloading mechanisms 2 are connected horizontally and vertically to height-increasing plates 6 and unloading mechanisms 2. Simultaneously, the multiple height-increasing plates 6 and unloading mechanisms 2 are connected horizontally, allowing for an increase in the number of devices in both directions, thus expanding the retaining area. The L-shaped support bases 1 and unloading mechanisms 2 are connected and fixed to the two unloading mechanisms 2, the upper and lower L-shaped support bases 1, and the height-increasing plates 6 via the connection port 32 and the connecting column 33. By connecting the curved surface 31, the upper and lower curved support plates 21 are fixed with multiple bolts, and by connecting the height-increasing plate 6 and the L-shaped support base 1 with the double-layer support plate 37, stable support is provided when the height of the device is increased. By inserting and fixing the L-shaped support base 1, the curved support plate 21 and the connecting rod 35 on one side of the height-increasing plate 6 to the connecting port 34 on the other side, stable support is provided when the horizontal length of the device is increased. Through the setting of the connecting part 3, the device can be adjusted in time according to the actual area of ​​the masonry retaining wall and maintain a stable effect.

[0038] like Figures 1 to 4As shown, the retaining device for highway subgrade masonry provided in this embodiment has a support part 4 on the side of the L-shaped support base 1 away from the unloading mechanism 2. The support part 4 is used for overall fixation of the device. The support part 4 includes an arc-shaped support frame 41 that is fixedly connected to the height increasing plate 6 and the double-layer support plate 37. The arc-shaped support frame 41 has a support card interface 47 inside. There are several support card interfaces 47. The support card interface 47 is connected to a support card connector 48. The side of the support card connector 48 away from the support card interface 47 is fixedly connected to a first support rod 42. Several first support rods 42 are simultaneously fixedly connected to a double-layer support base 43. The double-layer support base 43 is fixedly connected to an L-shaped support plate 44.

[0039] In this embodiment, when the device is in use, the arc-shaped support frame 41 provides stable support for the support card interface 47 under the support of the double-layer support plate 37 and the height-increasing plate 6, ensuring accurate positioning when the support card interface 47 and the support card connector 48 are engaged. Through the connection of multiple support card connectors 48 with the first support rod 42, the double-layer support base 43, supported by the first support rod 42 and the L-shaped support plate 44, simultaneously supports the height-increasing plate 6 and the double-layer support plate 37. Through the connection and support between multiple devices, the device can transmit and relieve pressure when subjected to pressure. By engaging and fixing the support card connector 48 and the support card interface 47 inside the arc-shaped support frame 41, the first support rod 42 and the double-layer support base 43 can achieve accurate positioning and will not be offset by pressure when supported, thereby improving the accurate positioning of the device when performing soil retention support.

[0040] like Figure 3 As shown, the retaining wall device for highway subgrade masonry provided in this embodiment has an L-shaped support base 1 fixedly connected to a second support rod 45 via a bottom support plate 36, and a bottom support base 46 fixedly connected to the second support rod 45. The bottom support base 46 is fixedly connected to the L-shaped support base 1 and is located below the bottom support plate 36. The bottom support base 46 is located between the L-shaped support plate 44 and the L-shaped support base 1.

[0041] In this embodiment, when the device is supported, the L-shaped support base 1 and the second support rod 45 are connected by the bottom support plate 36, so that the second support rod 45 provides support force to the L-shaped support base 1 under the support of the bottom support base 46, thereby achieving the effect of supporting the entire device. At the same time, since the bottom support base 46 and the L-shaped support plate 44 are located on the same horizontal plane, the bottom support base 46 and the L-shaped support plate 44 can provide support to the device simultaneously. When the L-shaped support plate 44 is fixed, it can fix the position of the bottom support base 46, thereby improving the stability of the support force and the fixation of the direction when the bottom support base 46 is supporting, thus improving the stability and efficiency of the device when supporting the retaining wall.

[0042] Working principle: When the curved support plate 21 faces pressure, it transmits force to multiple connecting plates 23 behind it through the connection of the curved connecting block 22. The hyperboloidal action of the curved support plate 21 itself buffers the force at two different angles, effectively mitigating and dissipating the force transmitted to the curved connecting block 22. Simultaneously, the support of the aggregate connecting rod 24 and the formation of multiple triangular support structures between the support curved column 25 and the support straight column 26 provide stable soil retention support during roadbed masonry work, supported by multiple connected devices and the L-shaped support base 1. Furthermore, with the opening of the flow port 52 and the discharge port 53, the soil below flows into the flow port 52 under the support of the multiple discharge ports 53. The soil flows through the flow chamber 51, which has a downward-sloping curved bottom. Under the weight of the soil itself, it flows towards the discharge port 53. At the same time, the blocking block 54 blocks the soil flow, causing the soil to accumulate inside the flow chamber 51. This allows the soil and the L-shaped support base 1 to form a whole, thus achieving a stable support effect at the bottom of the device. The soil pile below the device can be discharged under the flow of the flow chamber 5, reducing the pressure on the entire device. The soil is fixed inside the flow chamber 5, making the soil pile and the L-shaped support base 1 a whole, providing a stable support effect below the device. Thus, through the setting of the unloading mechanism 2 and the flow chamber 5, the support effect of the retaining device can be improved through a simple structural connection.
