Description

Technical Field

[0001] This utility model belongs to the field of trench construction, and in particular relates to a safety protection and early warning device for construction in trenches. Background Technology

[0002] Currently, most of the protective measures used in trench construction are quite traditional, relying mainly on temporary support frames or simple barriers. These facilities only provide basic protection and have a very limited function, making them inadequate to address the complex risks that may arise during construction. Construction workers often struggle to detect potential safety hazards in a timely manner, and emergency response is frequently delayed once a danger occurs. By the time measures are taken after an accident, irreparable damage has often been incurred, severely impacting the safety of construction workers, project progress, and costs. Furthermore, these traditional protective measures are unable to detect and issue warnings in advance when the surrounding soil is unstable and shows signs of collapse.

[0003] Furthermore, existing protective devices are typically cumbersome to install, requiring significant manpower and time. They also lack adaptability, making it difficult to flexibly adjust to different trench structures and thus failing to meet diverse construction needs. Summary of the Invention

[0004] In view of this, the present invention aims to overcome the defects in the prior art and propose a construction safety protection and early warning device in trenches.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A construction safety protection and early warning device in a trench includes an inner support mechanism and two side protection mechanisms. The two ends of the inner support mechanism are respectively connected to the corresponding side protection mechanisms. Each side protection mechanism is equipped with an early warning mechanism. The side protection mechanisms are located on the trench foundation, and the early warning mechanisms are connected to the original soil of the excavated slope.

[0007] The internal support mechanism includes an inner sleeve and two L-shaped inner support square tubes. Both ends of the inner sleeve are movably connected to the inner support square tubes, which are connected to corresponding side protection mechanisms. The support square tubes are fitted over the outer side of the inner sleeve. Both the support square tubes and the inner sleeve have adjustment holes, and after adjustment, they are connected by fixing bolts. The adjustment holes allow for adaptation to trenches of different widths, meeting the needs of various construction scenarios.

[0008] Furthermore, the early warning mechanism includes a measuring rod and an early warning component. One end of the measuring rod is connected to the undisturbed soil of the excavated slope, and the other end is connected to the early warning component.

[0009] Furthermore, one end of the measuring rod is provided with a front end plate and the other end is provided with a rear end plate. The front end plate is provided with a touch probe, which cooperates with the early warning component. The rear end plate is provided with a soil anchoring section.

[0010] Furthermore, the warning component includes a protective box and an alarm. The protective box is located on the baffle square tube, and a bracket is installed inside the protective box. A switch is mounted on the bracket, and the position of the switch corresponds to the touch probe. The alarm is located on top of the side protection mechanism and is connected to the switch via wiring. The alarm and switch can be provided with continuous and stable power by a lithium battery. Even on cloudy days or at night, the device can operate normally, ensuring long-term stable operation in environments without a power grid. To meet the needs of frequent relocation and rapid installation at construction sites, the warning component can be fixed using magnetic attachment. Construction personnel can complete the installation and disassembly of the device in a short time, greatly improving construction efficiency and facilitating the transfer and reuse of the device between different construction locations.

[0011] Furthermore, a fastener is provided on the measuring rod, and the fastener is threadedly connected to the measuring rod.

[0012] Furthermore, the side protection mechanism includes a baffle square tube, inside which a side support square tube is provided, and a steel mesh is provided between the side support square tube and the baffle square tube. A lifting lug is provided on the top of the baffle square tube, and overlapping lugs and strut mounting holes are provided on both sides of the baffle square tube. The inner support mechanism and the side protection mechanism are connected through the strut mounting holes.

[0013] Furthermore, the bottom of the baffle square tube is provided with a brake-type directional wheel, and a track is provided on the groove base, the track cooperating with the brake-type directional wheel.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] The trench construction safety protection and early warning device of this utility model is equipped with an internal support mechanism and a side protection mechanism. It adopts a modular design and uses square tubes to make a load-bearing frame, which not only facilitates transportation and storage, but also makes it easy to quickly assemble and disassemble on the construction site. At the same time, it forms a "gate"-shaped stable protection in the trench. The bottom of the side protection mechanisms is close to the bottom of the trench slope, and its main function is to prevent the trench slope from collapsing and the surrounding soil and rocks from sliding, and to avoid objects falling from above and causing injury to construction personnel during the construction process.

[0016] The early warning mechanism described in this utility model is reasonably positioned on the excavated surface of the trench sidewall, enabling real-time and accurate monitoring of soil displacement changes, providing early warning of the risk of trench slope collapse, and giving construction workers valuable time to take shelter. Once soil displacement is detected, the alarm quickly activates a high-frequency alarm sound and flashes warning lights to attract the attention of construction workers with strong audiovisual signals, reminding them to take timely safety measures.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figure 1-7 As shown, a construction safety protection and early warning device in a trench includes an inner support mechanism and two side protection mechanisms. The two ends of the inner support mechanism are respectively connected to the corresponding side protection mechanisms. Each side protection mechanism is equipped with an early warning mechanism. The side protection mechanisms are located on the trench foundation 15. The early warning mechanisms are connected to the original soil 16 of the excavated slope 14.

[0032] The inner support mechanism includes an inner sleeve 10 and two L-shaped inner support square tubes 8. Both ends of the inner sleeve 10 are movably connected to the inner support square tubes 8, and the inner support square tubes 8 are connected to corresponding side protection mechanisms. The support square tubes are fitted over the outer side of the inner sleeve 10. Both the support square tubes and the inner sleeve 10 are provided with adjustment holes 12. After adjustment, they are connected by fixing bolts 11. The adjustment holes 12 allow for adaptation to trenches of different widths, meeting the needs of various construction scenarios.

[0033] The warning mechanism includes a measuring rod 17 and a warning component. One end of the measuring rod 17 is connected to the undisturbed soil 16 of the excavated slope 14, and the other end is connected to the warning component. A front end plate 18 is provided at one end of the measuring rod 17, and a rear end plate 19 is provided at the other end. A contact probe 20 is provided on the front end plate 18, and the contact probe 20 cooperates with the warning component. A soil anchoring section 21 is provided on the rear end plate 19. The warning component includes a protective box 23 and an alarm 26. The protective box 23 is located on the baffle square tube 1. A bracket 24 is provided inside the protective box 23, and a switch 25 is provided on the bracket 24. The position of the switch 25 corresponds to the contact probe 20. The alarm 26 is located at the top of the side protection mechanism and is connected to the switch 25 via a wiring 27. The alarm 26 and the switch 25 can be provided with continuous and stable power support using a lithium battery. Even on cloudy days or at night, the device can operate normally, ensuring long-term stable operation even in environments without a power grid. To meet the needs of frequent relocation and rapid installation at construction sites, the early warning component can be fixed using magnetic attachment. Construction personnel can complete the installation and disassembly of the device in a short time, greatly improving construction efficiency and facilitating its transfer and reuse between different construction locations. A fastener 22 is provided on the measuring rod 17, and the fastener 22 is threadedly connected to the measuring rod 17. The length of the measuring rod 17 can be adjusted via the thread to meet the needs of various construction scenarios.

[0034] The side protection mechanism includes a baffle square tube 1, inside which a side support square tube 2 is installed.

After the task is completed, the brake device is released, and the device is pulled (or pushed) to the next task area, facilitating the movement of the device.

[0035] The early warning mechanism is installed between the trench excavation slope 14 and the protective box 23. During on-site installation, the protective box 23 is magnetically fixed to the side tube of the baffle square tube 1, and the magnetic alarm 26 is fixed to the horizontal tube of the baffle square tube 1. After the rear end plate 19 is subjected to deformation and creep of the excavation slope 14, the deformation sensor 17 transmits the deformation to the probe 20. The probe 20 is then triggered by the probe 17, which in turn triggers the switch 25. Through the wiring 27, a closed loop is formed with the magnetic alarm 26, thereby achieving the purpose of early warning. When the area of ​​one protective device is insufficient, the front and rear protective devices can be combined using the stacked lugs 5 to form a larger protective area, and this process can be repeated.
