Description

Technical Field

[0001] This utility model relates to the field of power inspection well technology, specifically a prefabricated power inspection well for roads. Background Technology

[0002] In the continuous advancement and development of urban municipal road construction, the rational planning, scientific layout, and efficient maintenance of underground power pipelines have become key links in ensuring the stability of urban power supply and the smooth operation of the city. As an indispensable and important node facility in the underground power pipeline system, power inspection wells undertake important functions such as power pipeline connection, inspection, maintenance, and personnel access. The quality of their performance and the rationality of their construction methods directly affect the stable operation of the entire power system, and also have a profound impact on the overall efficiency and quality of road construction and subsequent use and maintenance costs. In the past, most power inspection wells under municipal roads adopted the traditional cast-in-place concrete construction method. Under specific historical periods and construction conditions, this construction method has shown its flexibility to a certain extent. It can appropriately adjust the size and shape of the inspection well according to the actual geological conditions and underground pipeline layout, thereby meeting the connection and maintenance needs of underground power pipelines in different scenarios.

[0003] However, with the acceleration of urbanization, the number of underground power lines under municipal roads has surged. Traditional cast-in-place concrete inspection wells have long construction cycles, unstable quality, and are easily affected by the environment. Therefore, we need a prefabricated power inspection well for roads. Summary of the Invention

[0004] The purpose of this utility model is to provide a prefabricated road electrical inspection well to solve the existing problems mentioned in the background art, such as the rapid increase in the number of underground power lines under municipal roads due to the accelerated urbanization process, the long construction cycle and unstable quality of traditional cast-in-place concrete inspection wells, and their susceptibility to environmental impacts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated road electrical inspection well, comprising a sealing assembly, a fixing assembly disposed inside the sealing assembly, a cover plate disposed on the top of the sealing assembly, the sealing assembly comprising a base, a mating groove being formed on the top of the base, a sealing ring being fixedly connected inside the mating groove, a fixing wall being disposed inside the mating groove, and a positioning wall being disposed inside the mating groove.

[0006] Preferably, the base forms a fixed structure with the fixed wall through a docking groove, and the inner diameter of the docking groove matches the outer diameter of the fixed wall, and the inner wall of the docking groove fits snugly against the outer wall of the fixed wall.

[0007] Preferably, the base is fixed to the positioning wall by means of a docking groove, and the inner diameter of the docking groove matches the outer diameter of the positioning wall, and the bottom of the positioning wall is inserted into the sealing ring inside the docking groove for fixation.

[0008] Preferably, the fixing component includes a pre-embedded screw rod, which is disposed inside the fixing wall. The outer wall of the pre-embedded screw rod is threaded with a nut. A reinforcing bar is fixedly connected to the top of the base. A support rod is fixedly connected to the top of the base. A template is fixedly connected to one side of the support rod. The reinforcing bar is installed inside the pouring groove.

[0009] Preferably, the base is fixed to the template by means of a support rod, and the bottom of the support rod is fixed to the top of the base, and one side of the support rod is fixed to one side of the template.

[0010] Preferably, the nut is connected to the fixed wall via a pre-embedded screw to form a threaded structure, and one end of the pre-embedded screw is fixed to the inside of the fixed wall. The inner diameter of the nut matches the outer diameter of the pre-embedded screw, and the outer wall of the pre-embedded screw fits against the inner wall of the nut.

[0011] Preferably, the positioning wall is detachable from the fixed wall by pre-embedded screws, and the pre-embedded screws pass through the positioning wall and are connected to the nuts.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In the scheme of this application: 1. To address the problems of long construction cycles, unstable quality, and susceptibility to environmental impacts in traditional cast-in-place concrete inspection wells caused by the surge in underground power lines under municipal roads due to rapid urbanization, this application proposes a solution. This involves placing the base in a pre-selected location, inserting the fixed wall and positioning wall into the mating groove of the base, and sealing the groove with a sealing ring. This completes the wall placement and initial sealing, significantly reducing installation difficulty, saving manpower and time costs, improving construction efficiency, ensuring the stability and cleanliness of the internal environment, enhancing the overall strength and stability of the wall, enabling it to withstand certain external impacts, and extending the wall's service life. 2. To address the issues of limited load-bearing capacity and irregular casting shape leading to poor sealing in existing power inspection wells, this application proposes a new method. This involves embedding bolts in the fixed wall, penetrating the positioning wall, and tightening them with nuts to ensure a tight fit. Reinforcing bars are placed inside the casting groove, and a formwork is installed and fixed with support rods. Concrete is then poured, and after drying, the formwork is removed, followed by the installation of the top cover. This process completes the installation and sealing of the inspection well, enhancing structural stability, effectively preventing displacement or loosening, significantly improving the load-bearing capacity, simplifying operation, providing excellent sealing, effectively preventing external debris and sewage infiltration, extending the service life of the inspection well, reducing subsequent maintenance costs, and ensuring the normal operation of underground facilities.
