[0002] With the acceleration of urbanization, the development and utilization of underground space has received increasing attention. As an important part of urban underground infrastructure, the construction of underground comprehensive pipeline corridors is of great significance for improving urban functions, optimizing urban layout, and improving urban disaster prevention and mitigation capabilities. However, traditional underground pipeline corridor construction methods have problems such as long construction period, high cost, and great impact on the environment, which are difficult to meet the needs of the rapid development of modern cities.

[0003] Traditional underground pipe gallery construction usually adopts cast-in-place concrete or masonry structure. These construction methods require a lot of on-site operations, including formwork construction, concrete pouring, masonry, etc., which not only have a long construction period, but also require a lot of labor and materials. In addition, on-site operations will also generate a lot of noise, dust and construction waste, which will have adverse effects on the environment. In order to overcome the shortcomings of traditional construction methods, prefabricated component technology has gradually been applied to the construction of underground pipe galleries in recent years. Prefabricated components have the advantages of short production cycle, controllable quality, fast construction speed and small environmental impact, which can significantly improve the construction efficiency and quality of underground pipe galleries. However, there are still some problems with the prefabricated components and their construction methods on the market, such as loose connection, poor waterproof performance, and low construction accuracy. These problems limit the widespread application of prefabricated component technology in the construction of underground pipe galleries. Summary of the invention

[0033] The shapes and sizes of the connection groove and the connection flange match, and a sealing strip is provided in the connection groove. When the connection flange is inserted into the connection groove, the sealing strip is compressed to form a seal to prevent groundwater from seeping into the interior of the pipe gallery.

[0034] The connecting device includes a bolt and nut assembly and an embedded part for fixing the bolt. The embedded part is pre-installed on the connecting groove or connecting flange of the prefabricated component. The bolt passes through the connecting groove and connecting flange of the adjacent prefabricated component and cooperates with the embedded part.

[0038] Brackets and fixtures are provided in the chamber of the prefabricated component to fix and support the pipeline to prevent displacement or damage during transportation and installation.

[0039] There is an entrance shaft at one end of the main body of the tunnel and an exit shaft at the other end. Stairs and lighting equipment are provided in the entrance shaft and exit shaft respectively to facilitate personnel entry and exit and pipeline connection.

[0040] In addition, the main body of the pipe gallery is the skeleton of the entire underground integrated pipe gallery, and its design needs to consider various factors such as soil pressure, groundwater pressure, and ground traffic load. The prefabricated components adopt a modular design, which is convenient for production, transportation and installation. At the same time, the size and shape can be adjusted according to actual needs to adapt to different terrains and pipeline requirements. The multiple chambers set inside each prefabricated component not only facilitate the classified layout of different pipelines, but also help reduce interference between pipelines and improve the utilization efficiency and safety of the pipe gallery.

[0041] High-strength, corrosion-resistant concrete is the preferred material for prefabricated components, which has good mechanical properties and durability. The design of the waterproof layer needs to consider factors such as material compatibility, construction convenience and waterproof effect, and can be in various forms such as coatings and rolls.

[0042] The design of the connection groove and the connection flange must take into account their shape, size and matching accuracy to ensure the stability and sealing of the connection. During the connection process, the cleanliness and matching clearance of the connection groove and the connection flange must be strictly controlled to prevent debris from entering the connection area and affecting the connection effect.

[0043] The design of the connection device needs to ensure a quick and stable connection between adjacent prefabricated components while meeting the waterproof requirements. In addition to bolt and nut assemblies, other connection methods such as welding and bonding can also be considered to improve the reliability and durability of the connection. The selection of sealing strips needs to consider their aging and corrosion resistance to ensure long-term and effective waterproofing.

[0044] Lifting devices and positioning and adjustment devices are key equipment for rapid construction. The lifting device must have sufficient lifting capacity and stability to ensure the safety of prefabricated components during the lifting process. The positioning and adjustment device must have high-precision measurement and adjustment capabilities to ensure the precise docking of prefabricated components. In addition, the use of automation and intelligent technologies, such as robots and drones, can also be considered to improve construction efficiency and safety.

[0045] During the hoisting process, it is necessary to ensure that the crane is operated smoothly and accurately to avoid collision or damage of prefabricated components during the hoisting process. The use of the positioning and adjustment device must be carried out strictly in accordance with the operating procedures to ensure that the horizontal and vertical positions of the prefabricated components meet the design requirements.

[0046] The setting of the inspection passage and ventilation system must take into account the passage and maintenance needs of personnel, as well as the air circulation inside the corridor. The width, height and lighting of the inspection passage must meet the requirements of personnel safety and comfort, and the ventilation system must be reasonably designed based on factors such as the length, width and height of the corridor to ensure the air quality and environmental humidity inside the corridor.

[0047] The design of pipeline supports and fixtures must take into account factors such as the type, size and weight of the pipeline to ensure the stability and safety of the pipeline. The materials of the supports and fixtures must have good mechanical properties and corrosion resistance, and the convenience of their installation and disassembly must also be considered.

[0048] The setting of entrance and exit wells must take into account the entry and exit of personnel and the connection requirements of pipelines. The configuration of stairs and lighting equipment must meet the requirements of personnel safety and comfort, and at the same time, the convenience of their maintenance and replacement must be considered. During the design and construction process, safety measures such as fire prevention and explosion prevention must also be considered.

[0049] In order to ensure the quality and safety of construction, professional training and guidance should be provided to construction personnel. The training content should include the operation skills of hoisting, positioning and adjustment, connection and fixation of prefabricated components, as well as knowledge of safety regulations and quality standards. Through training and guidance, the skill level and safety awareness of construction personnel can be improved to ensure the smooth progress of the construction process.
