Whether it is the bustling streets of the city or the quiet alleys of the countryside, construction wells play an important role silently. They are usually hidden underground and unnoticed, but they are an indispensable part of the operation of the city. Construction wells not only provide protection and support for underground pipelines, but also ensure the normal operation of important facilities such as electricity, communications, and water supply.

[0003] Nowadays, cable inspection wells usually need to be cast on site, which not only prolongs the construction period of the project, but also consumes a lot of time and human resources. In addition, the inspection wells cast on site are easily affected by environmental factors, which limits their application scope and makes their adaptability relatively low. Summary of the invention

[0004] The present invention provides a multi-chamber combined assembled prefabricated work well and an assembly method, which can reduce the construction period, increase the scope of application according to the required situation and provide safer protection for operators.

The two ends of the intermediate well body are respectively equipped with a socket slot and a socket block. The internal corners of the end well body and the intermediate well body are chamfered, and installation holes are provided near the chamfers. The intermediate well body is composed of multiple or single parts, and the two ends of a single or several intermediate well bodies are connected to the end well bodies at both ends by socket blocks and socket slots, and long bolts are inserted into the installation holes to achieve tight fixation between the well bodies to form a whole. The inner side surfaces of the end well bodies and the intermediate well bodies are fixedly connected with embedded iron sheets, and the upper surfaces of the embedded iron sheets are provided with threaded holes. A connecting plate is fixedly connected to the embedded iron sheet, and a number of racks for placing cables are fixed on the connecting plate.

[0006] Moreover, sealing grooves are provided at the sockets of the end well bodies and the middle well body, and waterproof sealing rings are embedded in the sealing grooves.

[0007] Moreover, a protective iron ring is fixedly connected to the middle of the upper surface of the end well body and the middle well body, a hole is set at the protective iron ring, a rotating shaft is rotatably connected near the hole, a manhole cover is fixedly connected to the middle of the rotating shaft, and a handle is fixedly connected to the upper surface of the manhole cover.
