Description
Technical Field
[0001] This utility model relates to the field of prefabricated pipe gallery, and in particular to a novel prefabricated three-compartment pipe gallery. Background Technology
[0002] The full name of a utility tunnel is an urban underground integrated utility tunnel, which is a public tunnel built underground in cities for the centralized laying of municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heating, and gas. Its construction effectively solves problems such as repeated road excavation, dense overhead power lines, and frequent pipeline accidents, greatly improving the efficiency of urban space utilization and the convenience of maintenance and management. Through centralized layout, utility tunnels significantly enhance the city's disaster prevention capabilities, ensure pipeline safety, and reduce maintenance costs in the long term. As an important part of modern urban infrastructure, utility tunnels are regarded as the lifeline for ensuring the operation of the city. The core meaning of prefabrication is to prefabricate all or most of the components such as houses in a factory. In the field of construction, this definition specifically refers to the standardized components such as concrete composite slabs and bridge slabs manufactured through industrialized production methods.
[0003] In the existing precast three-compartment pipe gallery connection process, the secondary pouring of the connection joint affects the construction period, the poor drainage capacity inside the pipe gallery and the humid environment affect the operation of the internal pipeline. Therefore, those skilled in the art have provided a new type of precast three-compartment pipe gallery to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel prefabricated three-compartment pipe gallery. By changing the connection method, the connection seams of the prefabricated three-compartment pipe gallery no longer require secondary pouring during the connection process, and the addition of internal drainage and protection functions ensures the stability of the internal pipe and line placement environment.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel prefabricated three-compartment pipe gallery, comprising a pipe gallery shell and pipe gallery compartments, wherein the pipe gallery compartments include a gas compartment, a water supply and drainage communication compartment, and a power compartment arranged side by side, and the pipe gallery shell includes a connecting structure; The connecting structure includes an outer shell body. A water-proof layer is provided inside the outer shell body near the center. Connecting grooves are provided around the front face of the outer shell body. The four connecting grooves are connected end to end to form a square. The rear faces of the four connecting grooves penetrate the front face of the connecting structure and extend into the interior of the connecting structure. Connecting plates are fixedly connected around the rear face of the connecting structure. The four connecting grooves are connected end to end to form a square. A water-stop strip is fitted on the outside of the four connecting plates. Through the above technical solution, a new type of prefabricated three-compartment pipe gallery has connecting grooves and connecting plates respectively set on the front and rear end faces of the pipe gallery shell during the manufacturing process. This is to ensure that two new prefabricated three-compartment pipe galleries can be tightly connected to each other during the connection process. The waterstop wrapped on the connecting plate is used to waterproof the connection point, which is more effective in waterproofing the pipe gallery.
[0006] Furthermore, drainage structures are fixedly connected to the lower part of both sides of the outer shell of the pipe gallery. The two drainage structures include two drainage ditches. The two drainage ditches are fixedly connected to the lower part of the two end faces of the connecting structure. Vertical drainage channels are fixedly connected to the end faces of the two drainage ditches that are close to each other.

A gas monitor is fixedly connected to the center of the inner wall of the gas chamber away from the center of the pipe rack shell. The above technical solutions facilitate the transportation and monitoring of gases.
[0008] Furthermore, multiple pipe communication frames are fixedly connected to the inner walls on both sides of the water supply and drainage communication compartment. Water supply and drainage pipes are fixedly connected to the upper ends of the two lower pipe communication frames among the multiple pipe communication frames. A fan is fixedly connected to the center of the upper inner wall of the water supply and drainage communication compartment. The above technical solution facilitates the transmission of signals and wastewater, as well as the heat dissipation of cables.
[0009] Furthermore, multiple power line frames are fixedly connected to the inner walls on both sides of the power compartment; The above technical solution facilitates the orderly placement of electrical wires.
[0010] Furthermore, waterproof membranes are fixedly connected to all four inner walls of the pipe gallery. The above technical solutions further prevent moisture from entering the warehouse.
[0011] Furthermore, each adjacent compartment in the pipe gallery is fixedly connected with a heat insulation board; The above technical solution prevents heat generated during line operation from being transferred to another compartment through the concrete, thus affecting the service life of the line in that compartment.
[0012] This utility model has the following beneficial effects: 1. In this utility model, the new prefabricated three-compartment pipe gallery uses a tenon and mortise structure to set up a connecting groove and a connecting plate, so that two pieces of the new prefabricated three-compartment pipe gallery can be spliced together. This eliminates the need to pour concrete to form a connecting joint, reducing the construction period and making the connection more stable. The waterproof effect at the connecting joint is also better.
[0013] 2. In this utility model, the new prefabricated three-compartment pipe gallery is provided with drainage ditches and drainage channels inside and outside the outer shell, and waterproof plates and water-proof layers are provided inside the pipe gallery compartments to more effectively drain and isolate water from the outside, preventing the pipe gallery from being damp inside and affecting the structural stability.
[0014] 3. In this utility model, the novel prefabricated three-compartment pipe gallery utilizes a heat insulation plate installed between two compartments to prevent heat generated during operation between the two compartments from being transferred to the other compartment through the wall and affecting the service life of electronic products in the other compartment.
