Description

TECHNICAL FIELD

[0001] The utility model relates to a safety passageway structure for foundation pit construction. BACKGROUND

[0002] In order to ensure the safety and stability of the underground space formed by excavating the ground during the construction of underground structures, the required retaining structure, groundwater control, environmental protection and other measures are referred to as foundation pit engineering.

[0003] The safety passageway structure in the foundation pit engineering generally uses a connecting steel pipe as a connecting component to form an upward safety passageway, which facilitates the construction personnel to leave the foundation pit. In the event of extreme conditions such as the rise of underground water, the construction personnel need to quickly leave the foundation pit from the safety passageway. If such an extreme condition occurs at night, the total power supply is easily damaged by water, and after the light source of the safety passageway is turned off, the construction personnel cannot quickly find the safety passageway, which leads to a safety accident.

[0004] In view of the above problem that the light source of the safety passageway is disconnected and a safety accident is caused when extreme conditions such as the rise of underground water occur, a solar independent light indication structure is designed to overcome the above problem. SUMMARY

[0005] In order to overcome the problem that the light source of the safety passageway is disconnected and a safety accident is caused when extreme conditions such as the rise of underground water occur.

[0006] The technical scheme of the utility model is as follows: a safety passageway structure for foundation pit construction, comprising a support rod, an upper protective rod and a lower protective rod, further comprising a positioning hole and a connecting rod, the upper end of the support rod is provided with the upper protective rod on both sides, the lower end of the support rod is provided with the lower protective rod on both sides, the lower protective rod is provided with the positioning hole, the connecting rod is arranged on the positioning hole, the upper protective rod is provided with a prompting mechanism for reminding the position of the safety passageway, and the support rod is fixedly connected with the upper protective rod and the lower protective rod through a connecting mechanism.

[0007] Preferably, the support rod is inserted into the soil as a support structure, the upper protective rod serves as a handrail to facilitate the construction personnel to hold it, the connecting rod is sequentially inserted into the positioning holes on the lower protective rod, and the structure formed by the connecting rod and the lower protective rod serves as a step to facilitate the construction personnel to walk on it. The prompting mechanism uses solar energy to charge, and at night, the light emitting component on the upper protective rod is used to prompt the position of the passageway. In the event of an accident, the construction personnel can quickly evacuate from the passageway. The connecting mechanism installs the upper protective rod and the lower protective rod on the support rod and can rotate the angle of the upper protective rod and the lower protective rod, thereby adapting to the installation of different terrains.

[0008] Preferably, the warning mechanism includes a threaded connector, a connecting arm, a battery, an indicator light, and a ring-shaped solar panel. Threaded connectors are provided at both ends of the upper guard rod, with connecting arms threaded onto the connectors. A battery is housed within the connecting arm, and an indicator light is mounted on the battery. A ring-shaped solar panel is fixedly connected to the upper guard rod. The ring-shaped solar panel is divided into two parts: the indicator light is used to indicate the location of the safety passage to construction workers at night, facilitating identification and improving the escape rate; and the ring-shaped solar panel replenishes the battery with power.

[0009] Preferably, the connecting arm has openings on both sides, and indicator lights are set at the openings on both sides of the connecting arm. The upper guardrails form the route of the passage, so that the indicator lights on the upper guardrails can illuminate all parts of the passage, making it convenient for construction workers to pass through.

[0010] Preferably, the upper guard rod is provided with a through hole, through which the power supply cable of the ring solar panel is connected to the battery. This structure not only does not affect the ring solar panel's power supply to the battery, but also has a compact structure that is easy to use and transport.

[0011] Preferably, the connecting mechanism includes a positioning ring one, a positioning ring two, a connecting seat, a connecting component one, and a connecting component two. The upper guard rod is provided with a positioning ring one, and the support rod is provided with a positioning ring two. Both positioning ring one and positioning ring two are fixedly connected with connecting seats. The two connecting seats are rotatably connected by connecting component one. Both positioning ring one and positioning ring two are provided with connecting component two. Both connecting component one and connecting component two are composed of bolts and nuts. Connecting component two is used to tighten positioning ring one and positioning ring two. Positioning ring one is used to fix the two ends of the upper guard rod and the two ends of the lower guard rod. Positioning ring two is used to install the upper guard rod and the lower guard rod on the support rod. Connecting component one rotatably connects the two connecting seats together, thereby facilitating the rotation and angle change of positioning ring two. Connecting component two is used to tighten positioning ring one and positioning ring two.

[0012] Preferably, the bolt in the first connecting component passes through the contact surfaces of the two connecting seats. The connecting seats have openings, and the nut in the first connecting component is located inside the opening of the connecting seat. When it is necessary to separate and remove the first positioning ring and the second positioning ring, a wrench is used to enter through the opening of the connecting seat and unscrew the nut, thereby separating the two connecting seats.

[0013] Preferably, both positioning ring one and positioning ring two are provided with holes. The bolts in connecting component two pass through the holes and the nuts of connecting component two are tightened, thereby completing the fastening of positioning ring one and positioning ring two.

[0014] The beneficial effects of this utility model are:

[0015] 1. The facility uses solar energy for charging, eliminating the need for an additional power source. At night, the luminous components on the upper guardrail indicate the location of the passageway to construction workers, allowing them to quickly evacuate in case of an accident.

[0016] 2. The connecting mechanism installs the upper and lower guard rods on the support rod, and the angles of the upper and lower guard rods can be rotated to adapt to different terrains. Attached Figure Description
