Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, specifically to an adaptive temporary passage device for underground trenches and its construction method. Background Technology
[0002] Currently, in basements, equipment rooms, and factory projects, trenches are commonly used for the layout and organization of drainage, pipes, and cables. However, the width and depth of these trenches are not uniform, and how to reduce the low efficiency of horizontal transportation caused by the area division caused by the trenches is a current problem in on-site construction.
[0003] The construction sequence of a trench is as follows: trench excavation, trench leveling, trench subbase construction, trench reinforcement binding, trench formwork erection, trench concrete pouring, trench formwork removal, tongue-and-groove angle steel welding, subbase pouring, surface concrete pouring, and installation of trench covers and grates. The trench construction process is complex, time-consuming, and has a wide impact. During building structure construction, construction personnel and equipment frequently need to pass through trenches. On construction sites, temporary passageways are often created using formwork, timber, or filled trenches. These methods are neither safe nor economical, and are essentially one-time access routes.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention
[0005] To overcome the shortcomings of existing technologies, an adaptive temporary passage device for trenches and its construction method are provided to solve the problems of unsafety and low reusability of existing temporary passage methods for trenches.
[0006] To achieve the above objectives, an adaptive temporary passage device for underground trenches is provided, comprising:
[0007] The bridge deck has guide slopes formed at the top of its opposite ends, the upper edge of which is connected to the top surface of the bridge deck. Anti-slip pads are laid at the bottom of its opposite ends, and ear plates are formed on its opposite sides.
[0008] Two top support plates are disposed below the opposite ends of the bridge plate;
[0009] The telescopic assembly includes two socket sleeves and a connector. One end of each of the two socket sleeves is connected to the opposite side of the two top support plates. Both ends of the connector are movably inserted into the other ends of the two socket sleeves. An elastic support for pushing the connector is installed in the socket sleeve. The connector is connected to the bottom of the bridge plate by a hanger.
[0010] The drive assembly includes a fixed pulley and a traction cable. The fixed pulley is rotatably mounted on the bottom of the bridge plate. The middle part of the traction cable is wound around the fixed pulley. One end of the traction cable is detachably mounted on the ear plate. The insertion tube has a through hole. The other end of the traction cable is movably inserted through the through hole and connected to the socket sleeve. After pulling one end of the traction cable, the other end of the traction cable drives the two socket sleeves to move towards each other, so that the distance between the two top support plates is adapted to the width of the trench.
[0011] Furthermore, the elastic support is a helical spring.
[0012] Furthermore, a steering pulley is rotatably mounted in the middle of the insertion tube, the steering pulley being positioned opposite the through hole, and the other end of the traction cable being wound around the steering pulley.
[0013] Furthermore, a tension pulley is rotatably mounted on the bottom of the bridge deck, and the middle part of the traction cable is wound around the tension pulley. The tension pulley is positioned at a height higher than the fixed pulley.
[0014] Furthermore, a reinforcing rib is formed at the bottom of the bridge plate, and the reinforcing rib is arranged along the length direction of the bridge plate.
[0015] Furthermore, the reinforcing rib has a groove, which is provided along the length of the reinforcing rib, and the socket sleeve is connected to a guide rod, the upper end of which slides in the groove.
[0016] Furthermore, the ear plate has a vertical through hole, one end of the traction cable is movably inserted into the vertical through hole, and one end of the traction cable is connected to a locking block, which abuts against the upper part of the ear plate.
[0017] This invention provides a construction method for an adaptive temporary passage device for trenches, comprising the following steps:
[0018] The bridge deck is installed along the width of the trench;
[0019] After pulling one end of the traction cable of the drive assembly, the other end of the traction cable drives the socket sleeves of the two telescopic components to move towards each other, so that the distance between the two top support plates is adapted to the width of the telescopic trench.
[0020] The anti-slip pads at opposite ends of the bridge plate are placed on the ground planes on opposite sides of the trench, so that the two top support plates are embedded in the trench.
[0021] Release one end of the traction cable so that the two top support plates abut against the two opposite walls of the trench.
[0022] The beneficial effects of this invention are as follows: the adaptive temporary passage device for trenches has high load-bearing capacity. Compared with conventional timber and formwork, the bridge deck is made of steel, and the vertical stiffening steel beams are welded together, significantly improving the planar load-bearing capacity and bending resistance, effectively supporting the passage of personnel and small construction machinery. The adaptive temporary passage device for trenches is portable to install and dismantle. Through the coordinated operation of the traction cable, rotating shaft, socket sleeve, and spring, the device can be quickly installed and removed. The adaptive temporary passage device for trenches is reusable. By changing the structural dimensions of the socket sleeve, it can be adapted to trench walls of different sizes within a certain range. After use in a certain area, only simple maintenance is required before it can be put back into use. Attached Figure Description

[0030] Reference Figures 1 to 4 As shown, the present invention provides an adaptive temporary passage device for trenches, comprising: a bridge plate 1, a top support plate 2, a telescopic component 3, and a drive component 4.
[0031] In this embodiment, the bridge plate 1 is elongated. Guide slopes 10 are formed at the top of opposite ends of the bridge plate 1 along its length. The upper edge of the guide slopes 10 is connected to the top surface of the bridge plate 1.
[0032] Anti-slip pads 11 are laid on the bottom of opposite ends of the bridge plate 1. In this embodiment, the anti-slip pads are rubber or silicone.
[0033] See Figure 3 and Figure 4 As shown, ear plates 12 are formed on opposite sides of the bridge plate 1.
[0034] There are two top support plates 2. The two top support plates are set below the opposite ends of the bridge plate 1.
[0035] The telescopic assembly 3 includes a socket sleeve 31, a plug tube 32, a hanger rod 33, and an elastic support member 34.
[0036] The number of socket sleeves 31 is two. One end of each socket sleeve 31 is connected to the opposite side of the two top support plates 2. In some embodiments, the top support plate is hinged to one end of the socket sleeve.
[0037] Both ends of the insertion tube 32 are movably inserted into the other ends of the two socket sleeves 31. Elastic supports 34 are installed in the socket sleeves 31. The elastic supports 34 are used to push the insertion tube 32. The insertion tube 32 is connected to the bottom of the bridge plate 1 via a hanger 33.
[0038] In this embodiment, the telescopic assembly is arranged along the length of the bridge plate. The hanger is located at the middle of the insertion tube. The elastic support 34 is a helical spring. One end of the helical spring is connected to one end of the insertion tube, and the other end of the helical spring is connected to the socket sleeve. The helical spring is arranged along the axial direction of the socket sleeve.
[0039] The drive assembly 4 includes a fixed pulley 41 and a traction cable 42. The fixed pulley 41 is rotatably mounted on the bottom of the bridge plate 1. There are two fixed pulleys. The two fixed pulleys are respectively arranged on the bottom of opposite sides of the bridge plate.
[0040] There are two traction cables. Specifically, the middle of each traction cable 42 is wound around the fixed pulley 41. One end of the traction cable 42 is detachably installed on the ear plate 12. The insertion tube 32 has a through hole. The other end of the traction cable 42 is movably inserted through the through hole and connected to the socket sleeve 31.
[0041] After pulling one end of the traction cable 42, the other end of the traction cable 42 drives the two socket sleeves 31 to move towards each other, so that the distance between the two top support plates 2 is adapted to the width of the trench 5.
[0042] For a preferred implementation method, please refer to [link / reference]. Figure 2 and Figure 3 As shown, a steering pulley 35 is rotatably mounted on the middle of the insertion tube 32. The steering pulley 35 is positioned opposite to the through hole. The other end of the traction cable 42 is wound around the steering pulley 35.
[0043] In this embodiment, a tension pulley 43 is rotatably mounted on the bottom of the bridge plate 1. The middle part of the traction cable 42 is wound around the tension pulley 43. The tension pulley 43 is positioned higher than the fixed pulley 41. The tension pulley, fixed pulley, and steering pulley are arranged in a triangular configuration.
[0044] See Figure 1 As shown, a reinforcing rib 13 is formed at the bottom of the bridge plate 1. The reinforcing rib 13 is arranged along the length direction of the bridge plate 1.
[0045] In this embodiment, the reinforcing rib 13 has a groove. The groove is provided along the length of the reinforcing rib 13. The socket sleeve 31 is connected to a guide rod 36. The upper end of the guide rod 36 slides in the groove.
[0046] See Figure 3 and Figure 4 As shown, the ear plate 12 has a vertical through hole. One end of the traction cable 42 is movably inserted through the vertical through hole. One end of the traction cable 42 is connected to a locking block 37. The locking block 37 abuts against the upper part of the ear plate 12.
[0047] This invention provides a construction method for an adaptive temporary passage device for trenches, comprising the following steps:
[0048] S1. Set the bridge plate 1 along the width direction of the trench 5.
[0049] S2. After pulling one end of the traction cable 42 of the drive assembly 4, the other end of the traction cable 42 drives the socket sleeves 31 of the two telescopic assemblies 3 to move towards each other, so that the distance between the two top support plates 2 is adapted to the width of the telescopic trench 5.
[0050] S3. Place the anti-slip pads 11 at the opposite ends of the bridge plate 1 on the ground plane layer 6 on the opposite sides of the trench 5, so that the two top support plates 2 are embedded in the trench 5.
[0051] S4. Release one end of the traction cable 42 so that the two top support plates 2 are supported on the opposite two trench walls of the trench 5.
[0052] The adaptive trench temporary passage device of the present invention is mainly divided into two parts: a bridge plate for bearing the load and a locking structure for fixed installation.
[0053] The bridge deck is primarily a steel structure, with an anti-slip pad layer made of wear-resistant, flexible material in contact with the ground. The bridge deck is truncated pyramidal in shape, divided into a slope zone and a load-bearing zone. The slope zone features a guide ramp with a slight upward incline, allowing heavy machinery to access the load-bearing zone. The load-bearing zone is the central area of the bridge deck, with vertical bending-resistant components (such as reinforcing ribs) along the bending direction at the bottom of the deck, effectively resisting the weight of heavy machinery when it passes.
[0054] The main mechanical components of the bridge deck are steel components, which are connected by welding or bolts. The part in contact with the ground is made of flexible and wear-resistant materials, such as rubber and silicone rubber, to protect the ground as much as possible without being crushed. At the same time, it can be reused many times and is easy to replace.
[0055] The top support plate moves in a direction perpendicular to the trench. Under the action of the elastic support, the top support plate can effectively generate sufficient friction with the inner side of the trench wall under external disturbance, which is enough to support the entire device.
[0056] The top support plate is hinged to the socket sleeve, allowing the top support plate to contact the trench sidewall at a certain angle.
[0057] Under the action of the traction cable, the deformation of the helical spring is changed, which causes the sliding socket sleeve to move, so that the top support plate can complete the contact and separation with the side wall of the trench.
[0058] The adaptive trench temporary passage device of the present invention is transported to the designated location and installed at the location where the device needs to be installed.
[0059] Lift the device at the trench wall, pull up the locking blocks on both side ears, and compress the helical spring inward using the traction cable. The compression of the helical spring causes the sliding socket sleeve to contract, which in turn retracts the top support plate inward. After the helical spring is fully compressed, keep its deformation constant and place the device into the trench wall. Then release the traction cable; the deformation of the helical spring will be partially eliminated, and the sliding socket sleeve will expand outward under the action of the helical spring, causing the top support plate to press tightly against the trench wall sidewall, generating sufficient friction to support the entire system. The device installation is now complete. When it is necessary to remove the device, compress the helical spring again by pulling the traction cable to separate the top support plate from the trench wall sidewall. Finally, lift the device and release the traction cable to remove it.
[0060] If the top support plate is insufficient to generate enough friction to support the device in place, the bridge plate of the device can be placed directly on the top of the trench side wall. In this case, the locking mechanism plays an auxiliary role in preventing the entire device from shaking during use.
[0061] The adaptive trench temporary passage device of the present invention has high load-bearing capacity. Compared with conventional timber and formwork, the bridge plate is made of steel and welded with vertical stiffening steel beams, which greatly improves the planar load-bearing capacity and bending resistance, and can effectively carry personnel and small construction machinery to pass through.
[0062] The adaptive trench temporary passage device of the present invention is portable in installation and removal. Through the cooperation of the traction cable, the rotating shaft, the socket sleeve and the spring, the device can be quickly installed and removed.
[0063] The adaptive temporary passage device for trenches of the present invention is reusable. By changing the structural dimensions of the socket sleeve, it can be applied to trench walls of different sizes within a certain range. After use in a certain area, it can be put back into use with only simple maintenance.
[0064] Throughout the entire construction process of the trench, three forms of the trench wall are involved: the trench wall in the foundation soil state, the trench main body stage, and the trench wall after the ground is completed and before the cover grates are installed. In all three states, the device can be made to contact the side wall of the trench wall by the top support plate of the adaptive trench temporary passage device of this invention, thereby generating friction to fix the device. Furthermore, the material of the adaptive trench temporary passage device of this invention is steel structure, and the upper bridge plate can also be directly placed on the plane. In summary, this device is applicable to the entire life cycle of trench construction.
[0065] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
