Description

Technical Field

[0001] The utility model belongs to the technical field of construction structures, and in particular relates to a coastal assembled pipe gallery connection node. Background Art

[0002] A pipe gallery is a municipal utility tunnel space built underground in a city. It lays various municipal utility pipelines in one structure. By pouring concrete in a mold, a single pipe gallery is formed, and an underground foundation pit is dug. Both ends of the foundation pit are connected for assembly.

[0003] The current coastal pipeline corridor system has the following defects during assembly:

[0004] 1. Due to the reasons of the coastal underground base, the base support in the pit is insufficient, especially the connection between adjacent pipe gallery parts is not stable enough, the support is insufficient, the pipe gallery system has uneven bending force, and leakage and structural damage occur at the later connection nodes.

[0005] 2. Adjacent pipe gallery parts are connected by prefabricated plug-in structures, and rubber rings are installed on the protruding ends of the pipe gallery parts. They are hoisted and connected to the embedded ends of adjacent pipe gallery parts to achieve a sealing effect. However, damage to the rubber ring structure and later aging will lead to leakage problems. The protruding ends of the pipe gallery parts are connected with the embedded ends of the pipe gallery parts. During the later use, the protruding ends of the pipe gallery parts will be broken due to external forces.

[0006] In summary, the connection nodes of the current coastal pipeline corridor system are not stable enough and are prone to leakage. Therefore, we propose a coastal prefabricated pipeline corridor connection node. Utility Model Content

[0007] The utility model aims to provide a coastal assembled pipe gallery connection node to solve the technical problems of unstable connection and easy leakage at the connection node, so as to achieve the purpose of improving the structural stability of the connection node and avoiding water seepage.

[0008] In order to solve the above technical problems, the utility model provides a coastal assembled pipe gallery connection node, including: a foundation pit opened based on a preset line of the pipe gallery system and a single pipe gallery component built and connected in the foundation pit, the pipe gallery system is formed in the foundation pit through the pipe gallery components, adjacent pipe gallery components are connected by metal sleeves, cement supports are cast on both sides of the bottom of the pipe gallery components close to adjacent pipe gallery components, a metal frame is provided on the outer sleeve of the joint between adjacent pipe gallery components, the metal frame is designed to be open towards the surface and top of the pipe gallery component, and concrete is cast inside the metal frame to form a core, and the metal frame is connected to the joint between adjacent pipe gallery components through the core.

[0009] Furthermore, the two ends of the pipe gallery component are a protruding end and an embedded end respectively, the metal sleeve is larger than the outer wall size of the protruding end and smaller than the inner wall size of the embedded end, and is clamped around the outer wall of the protruding end.

[0010] Furthermore, the cement support is cast in the foundation pit through a mold, and during the casting process, a number of supporting columns are inserted through the interior of the cement support and connected to the base surface below the foundation pit.

[0011] Furthermore, a clamping groove is formed at the top of the cement support during the pouring process, and the length of the clamping groove is matched with the bottom length of the pipe gallery component.

[0012] Furthermore, the metal frame is made of iron metal, and steel bars are arranged inside the metal frame.

[0013] Furthermore, the metal frame adopts an upper and lower split design, including a lower frame and an upper frame, the lower frame is located at the bottom of the joints between adjacent pipe gallery parts, and the upper frame is located on both sides and the top of the joints between adjacent pipe gallery parts, and the inner wall size of the metal frame is adapted to the outer wall size of the pipe gallery parts.

[0014] Furthermore, docking pieces and plug-in pieces are welded to the two sides of the lower frame and the upper frame respectively, and the plug-in piece is inserted into the docking piece to complete the assembly of the metal frame.

[0015] The beneficial effects of the utility model are:

[0016] 1. By using metal sleeves to connect adjacent pipe gallery components and pouring cement supports on both sides of the bottom of the pipe gallery components, the overall stability of the pipe gallery system is greatly enhanced. In particular, in view of the problem of insufficient support of the coastal underground base, the cement supports and their internal supporting columns effectively improve the supporting capacity of the base surface in the pit and reduce the structural damage of the pipe gallery system caused by uneven bending force;

[0017] The above improves the structural stability, thereby preventing the structure at the joint of adjacent pipe gallery components from being subjected to external pressure and being squeezed, resulting in damage and leakage at the joint.

[0018] 2. The design of the metal sleeve and metal frame, combined with the concrete core cast inside, effectively improves the sealing of the joints of the corridor components. Compared with the traditional rubber ring sealing method, this design is extremely stable, not easy to age or damage, and avoids the possibility of leakage at the connection nodes.

[0019] By changing the connection mode of the adjacent pipe gallery parts as described above, the overall stability of the pipe gallery system is further improved.

[0037] The cement support 4 is cast in the foundation pit 1 through a mold, and during the casting process, several support columns 41 are inserted into the base surface below the foundation pit 1 through the cement support 4. The support columns 41 will provide additional supporting force to enhance the stability of the entire pipe gallery system.

[0038] A clamping groove 42 is formed at the top of the cement support 4 during the pouring process, and the length of the clamping groove 42 is matched with the bottom length of the pipe gallery member 2 .

[0039] like Figure 4 As shown, the metal frame 5 adopts an upper and lower split design, including a lower frame 52 and an upper frame 53.
