Description

Technical Field

[0001] This utility model relates to the technical field of steel corrugated pipe gallery and concrete pipe gallery joints, and more specifically, to a prefabricated steel corrugated pipe gallery and concrete pipe gallery joint structure. Background Technology

[0002] Integrated utility tunnels are underground urban pipeline corridors; they are tunnel spaces built underground in cities to integrate various engineering pipelines such as electricity, communications, gas, heating, water supply and drainage. They are equipped with dedicated inspection ports, hoisting ports and monitoring systems, and are subject to unified planning, design, construction and management. They are important infrastructure and "lifelines" to ensure the operation of cities. In current integrated utility tunnels, the node structures are generally constructed by drilling holes in concrete pipe tunnels and corrugated steel pipe tunnels and then welding them on site.

[0003] For example, CN215165807U discloses a prefabricated steel corrugated pipe gallery and concrete pipe gallery joint structure. The key technical points of the solution are: it includes pre-embedded bolts in the concrete pipe gallery and nuts welded to the surface of the steel corrugated pipe gallery. The bolts and nuts are used together. The steel corrugated pipe gallery and the concrete pipe gallery are integrally formed by cast-in-place. A water-stop steel plate is provided between adjacent nuts on the surface of the steel corrugated pipe gallery. A water-expanding strip is also provided near the water-stop steel plate. The main method is to pre-embed the bolts in the concrete pipe gallery and weld the nuts to the surface of the crests and troughs of the steel corrugated pipe gallery, and then integrally form it by cast-in-place. This not only avoids the defect of damage to the anti-corrosion layer caused by opening, but also prevents water leakage.

[0004] The above-mentioned prefabricated steel corrugated pipe gallery and concrete pipe gallery joint structure still has some shortcomings: since the prefabricated steel corrugated pipe gallery and concrete pipe gallery joint structure are connected by welding, once it is necessary to separate the prefabricated steel corrugated pipe gallery and concrete pipe gallery, it will increase the difficulty of the work and thus increase the time required for the work. Therefore, it is necessary to provide a prefabricated steel corrugated pipe gallery and concrete pipe gallery joint structure. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a prefabricated steel corrugated pipe gallery and concrete pipe gallery joint structure. By installing electric telescopic rods, when it is necessary to disassemble the prefabricated steel corrugated pipe gallery body from the concrete pipe gallery body, the two sets of electric telescopic rods inside the joint assembly are activated and retracted. Then, the electric telescopic rods drive the arc-shaped connecting plate and the stabilizing suction cup to move until the side wall of the stabilizing suction cup is separated from the surface of the prefabricated steel corrugated pipe gallery body. At this point, the prefabricated steel corrugated pipe gallery body and the concrete pipe gallery body can be separated. Because the electric telescopic rods have an automatic telescopic function, disassembly is more convenient, thus solving the problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a prefabricated steel corrugated pipe gallery and concrete pipe gallery node structure, including a concrete pipe gallery body, two limiting grooves are symmetrically opened on one side of the interior of the concrete pipe gallery body along the center, a limiting frame is bonded inside the limiting groove, a node component is connected inside the concrete pipe gallery body through the limiting frame, and a prefabricated steel corrugated pipe gallery body is connected inside the concrete pipe gallery body through the node component.

[0007] The limiting frame is made of rubber, and there are two limiting frames, with the height of the limiting frame being less than the depth of the limiting groove.

[0008] The node component includes a stabilizing connecting ring, and both sides of the stabilizing connecting ring are fixedly connected to limit connecting rods.

[0009] The surface of the limiting connecting rod is in contact with the inside of the limiting frame, and the length of the limiting connecting rod is less than the length of the limiting frame.

[0010] The stable connecting ring contains two electric telescopic rods that are symmetrically fixedly connected to the center, and one end of each electric telescopic rod is fixedly connected to an arc-shaped connecting plate.

[0011] The sidewall of the arc-shaped connecting plate is fixedly connected with multiple stabilizing suction cups in an arc-shaped array, and the sidewall of the stabilizing suction cups is in contact with the surface of the prefabricated steel corrugated pipe gallery body.

[0012] Wherein, the extension length of the electric telescopic rod is greater than the radius of the stabilizing connecting ring, and the length of the electric telescopic rod is greater than the length of the limiting connecting rod.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] 1. In the above scheme, the node structure is equipped with electric telescopic rods. When it is necessary to disassemble the prefabricated corrugated steel pipe gallery body from the concrete pipe gallery body, the two sets of electric telescopic rods inside the node component are activated to retract. Then, the electric telescopic rods will drive the arc-shaped connecting plate and the stabilizing suction cup to move until the side wall of the stabilizing suction cup is separated from the surface of the prefabricated corrugated steel pipe gallery body. At this time, the prefabricated corrugated steel pipe gallery body can be separated from the concrete pipe gallery body. Because the electric telescopic rods have the function of automatic extension and retraction, disassembly is more convenient.

[0015] 2. In the above scheme, the node structure is equipped with a limiting frame and a limiting connecting rod. When the node component needs to be replaced, only a frictional force greater than that between the limiting frame and the limiting connecting rod needs to be applied to pull out the node component. Because the limiting connecting rod is snapped into the limiting frame, it can be pulled out directly. Compared with other connection methods to connect the node component to the concrete pipe gallery body, this connection method saves more time when replacing it. Attached Figure Description

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] Example 1:

[0023] Please see Figure 1-3 A prefabricated steel corrugated pipe gallery and concrete pipe gallery node structure includes a concrete pipe gallery body 1. Two limiting grooves 2 are symmetrically opened on one side of the interior of the concrete pipe gallery body 1 along the center. A limiting frame 3 is bonded inside the limiting groove 2. A node component 4 is connected inside the concrete pipe gallery body 1 through the limiting frame 3. A prefabricated steel corrugated pipe gallery body 5 is connected inside the concrete pipe gallery body 1 through the node component 4.

[0024] The limiting frame 3 is made of rubber. There are two limiting frames 3, and the height of the limiting frame 3 is less than the depth of the limiting groove 2. The node component 4 includes a stabilizing connecting ring 41. Both sides of the stabilizing connecting ring 41 are fixedly connected to limiting connecting rods 42. The surface of the limiting connecting rods 42 is in contact with the inside of the limiting frame 3. The length of the limiting connecting rods 42 is less than the length of the limiting frame 3. Two electric telescopic rods 43 are fixedly connected symmetrically along the center inside the stabilizing connecting ring 41. One end of the electric telescopic rod 43 is fixedly connected to an arc-shaped connecting plate 44. The side wall of the arc-shaped connecting plate 44 is fixedly connected to multiple stabilizing suction cups 45 in an arc array. The side wall of the stabilizing suction cups 45 is in contact with the surface of the prefabricated steel corrugated pipe gallery body 5. The extension length of the electric telescopic rod 43 is greater than the radius of the stabilizing connecting ring 41, and the length of the electric telescopic rod 43 is greater than the length of the limiting connecting rod 42.

[0025] Benefits: The setting of the stabilizing suction cup 45 helps to ensure the quality of the prefabricated steel corrugated pipe gallery body 5 when connecting it, thereby reducing losses.

[0026] The working process of this utility model is as follows:

[0027] In order to facilitate the disassembly of the prefabricated corrugated steel pipe gallery body 5 and the concrete pipe gallery body 1 during use, the node structure is equipped with an electric telescopic rod 43. When it is necessary to disassemble the prefabricated corrugated steel pipe gallery body 5 and the concrete pipe gallery body 1, the two sets of electric telescopic rods 43 inside the node assembly 4 are activated and retracted. Then, the electric telescopic rods 43 will drive the arc-shaped connecting plate 44 and the stabilizing suction cup 45 to move until the side wall of the stabilizing suction cup 45 is separated from the surface of the prefabricated corrugated steel pipe gallery body 5. At this time, the prefabricated corrugated steel pipe gallery body 5 and the concrete pipe gallery body 1 can be separated. Because the electric telescopic rods 43 have an automatic telescopic function, disassembly is more convenient.

[0028] In the above scheme, the node structure is equipped with a limiting frame 3 and a limiting connecting rod 42 for replacing node component 4 during use. When it is necessary to replace node component 4, only a frictional force greater than that between the limiting frame 3 and the limiting connecting rod 42 needs to be applied to pull out node component 4. Since the limiting connecting rod 42 is snapped into the limiting frame 3, it can be pulled out directly. Compared with other connection methods to connect node component 4 to concrete pipe gallery body 1, this connection method saves more time when replacing it.
