Description

Technical Field

[0001] This utility model relates to the field of concrete pipe gallery technology, specifically to a precast reinforced concrete pipe gallery. Background Technology

[0002] Underground utility tunnels, also known as utility trenches, are municipal public facilities built underground in cities for laying municipal utility pipelines, subject to unified planning, design, construction, and maintenance. Urban integrated utility tunnels are underground tunnel spaces that integrate various engineering pipelines such as electricity, communications, gas, heating, and water supply and drainage. The tunnels are equipped with dedicated inspection ports, hoisting ports, maintenance and inspection channels, and detection and early warning systems, facilitating unified planning, design, construction, and management. They are vital infrastructure and "lifelines" ensuring the operation of cities.

[0003] The existing on-site casting of underground utility tunnels requires on-site processing of steel bars, binding, formwork, concrete pouring, curing, and formwork removal. This not only involves complex construction procedures and a long construction period, but also requires large storage and processing facilities for raw materials, which greatly complicates the already limited construction space. Utility Model Content

[0004] The purpose of this utility model is to provide a precast reinforced concrete pipe gallery to overcome the shortcomings of the existing technology. It can effectively improve the installation efficiency of underground pipe galleries, while reducing the storage of raw materials and the location of processing plants.

[0005] This utility model provides a precast reinforced concrete pipe gallery, including a pipe gallery body, wherein an installation groove and a first sealing groove are provided at one end of the pipe gallery body along the circumferential direction.

[0006] The other end of the pipe gallery body is provided with an installation protrusion adapted to the installation groove and a second sealing groove corresponding to the first sealing groove; the outer periphery of both ends of the pipe gallery body is provided with fixing blocks, and the fixing blocks are provided with installation holes, the center line of the installation through hole is parallel to the center line of the pipe gallery body.

[0025] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Embodiment 1 of this utility model:

[0027] like Figures 1-4 As shown, this utility model discloses a precast reinforced concrete pipe gallery, including a pipe gallery body 1 with a rectangular cross-section. One end of the pipe gallery body 1 has an installation groove 2 and a first sealing groove 3 along its circumferential direction. The other end of the pipe gallery body 1 has an installation protrusion 4 adapted to the installation groove 2 and a second sealing groove 5 corresponding to the first sealing groove 3. During actual installation, the installation groove 2 of one adjacent pipe gallery body 1 is fitted with the installation protrusion 4 of the other pipe gallery body 1, and water-swellable rubber strips are installed in the first sealing groove 3 and the second sealing groove 5. The installation of water-swellable rubber strips in the first sealing groove 3 and the second sealing groove 5 effectively prevents rainwater or groundwater from entering the pipe gallery body 1. The cooperation between the installation protrusion 4 and the installation groove 2 serves both as a positioning element and a sealing element, further improving the sealing performance.

[0028] Fixing blocks 6 are fixedly installed on the outer periphery of both ends of the pipe rack body 1. The fixing blocks 6 have mounting holes 61, the center line of which is parallel to the center line of the pipe rack body 1. Adjacent pipe rack bodies 1 are fixedly connected by bolts 9 passing through the corresponding mounting holes 61 on the fixing blocks 6. By setting the fixing blocks 6 and connecting adjacent pipe rack bodies 1 with bolts 9 passing through them, the fixing blocks 6 can be fixed in place, preventing displacement between adjacent pipe rack bodies 1 during long-term use. This prevents the distance between the pipe rack bodies 1 from increasing, which would lead to poor sealing at the connection point and allow external water to enter the interior of the pipe rack body 1.

[0029] Each end of the utility tunnel body 1 has three fixing blocks 6, which are respectively set on the top and two opposite sides of the utility tunnel body 1. In actual use, there can be multiple fixing blocks 6, which are set along the circumferential direction of the utility tunnel body 1.

[0030] In practical applications, the cross-section of the pipe gallery body 1 can also be circular, polygonal, etc.

[0031] Embodiment 2 of this utility model:

[0032] This embodiment is a further improvement on the first embodiment, and the parts that are the same as those in the first embodiment will not be repeated.

[0033] See Figure 1 As shown, to further increase the contact area between the utility tunnel body 1 and the foundation pit, and thus increase the connection strength, the following measures are also adopted: Extension plates 7 are provided on both sides of the bottom of the utility tunnel body 1. The length and thickness of the extension plates 7 can be set as needed; for example, the length of the extension plates 7 can be set to 10-40cm, and the thickness to 10-25cm. The extension plates 7 and the utility tunnel body 1 can be integrally formed.

[0034] Furthermore, to achieve better waterproofing, the distance between the first sealing groove 3 and the axis of the pipe rack body 1 is greater than the distance between the mounting groove 2 and the axis of the pipe rack body 1. The width of the first sealing groove 3 can be greater than the width of the mounting groove 2, or it can be less than or equal to the width of the mounting groove 2.

[0035] See Figure 5 As shown, to improve the strength of the utility tunnel body 1 and prevent damage during installation and transportation, a protective shell 8 is provided on the outer periphery of the utility tunnel body 1. The fixing blocks 6 are fixed to the protective shell 8 by welding or strong adhesive. The protective shell 8 can be made of metal or plastic.

[0036] To improve the waterproof effect, a waterproof layer can be applied to the outer periphery of the protective housing 8.

[0037] In practical use, protective shells 8 can be installed only on the top and opposite sides of the pipe gallery body 1, without a protective shell 8 at the bottom. A waterproof layer is applied to the outer surface of the protective shell 8 and the bottom of the pipe gallery body 1. See [reference needed]. Figure 6 As shown.

[0038] This utility model discloses a precast reinforced concrete pipe gallery, which is convenient and quick to install. Only a foundation pit needs to be dug beforehand. First, a precast reinforced concrete pipe gallery is hoisted into the pit. A water-swellable rubber strip is installed in the first sealing groove 3 of the pipe gallery body 1, protruding from the first sealing groove 3 to facilitate engagement with the second sealing groove 5 of the other pipe gallery body 1. Then, the other pipe gallery body 1 is hoisted into the pit, with its installation protrusion 4 inserted into the installation groove 2 of the first pipe gallery body 1. The second sealing groove 5 engages with the first sealing groove 3 until the opening of the second sealing groove 5 is flush with the opening of the first sealing groove 3, so that the portion protruding from the first sealing groove 3 is located within the second sealing groove 5. Finally, bolts 9 are passed through corresponding fixing blocks 6 of the two pipe gallery bodies 1 for fixation, ensuring the positions of the two pipe gallery bodies 1 remain fixed. (See attached diagram.) Figure 7 As shown in the diagram. This process can be repeated to connect multiple precast reinforced concrete pipe racks.

[0039] In the actual installation process, asphalt can also be laid at the connection between the two precast reinforced concrete pipe corridors to further improve the sealing effect.

[0040] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
