Description

Technical Field

[0001] This utility model relates to the field of underground integrated pipe gallery technology, specifically to an adjustable water supply support device for integrated pipe galleries. Background Technology

[0002] Water supply pipelines in integrated utility tunnels are typically installed using an overhead support system, with the supports usually being poured after the main tunnel structure is completed. Due to the limited space within the tunnel, in-situ casting of the supports is difficult, while precast supports cannot be tightly integrated with the main tunnel structure. Furthermore, once the supports are poured, subsequent installations of valves, branch tees, and pipe joints must be based on the completed support locations. This is particularly problematic for pipes with socket joints; improper support placement can severely impact the quality of water supply pipeline installation.

[0003] Chinese patent CN208982789U discloses a water supply pipeline support for underground utility tunnels. This patent allows for on-site installation based on the water supply pipeline's route within the tunnel. The support structure is compact and reasonable, facilitating installation and disassembly. Through the support platform and pipe clamps on the support, the water supply pipeline can be firmly and stably erected, improving the construction efficiency of water supply pipeline laying within the utility tunnel. While this patent offers convenience in support construction, it is more expensive than traditional concrete supports. Anchoring to the tunnel floor slab with anchor bolts requires drilling holes in the floor slab, which can damage the reinforcing steel. Furthermore, once fixed, if there is a conflict between the support and pipeline valves, fittings, or socket joints, the pipe section needs to be cut to accommodate the conflict, similar to traditional supports. Therefore, it still cannot completely solve the compatibility problem between the support and pipeline installation.

[0004] In summary, there is an urgent need for a prefabricated adjustable water supply support device for integrated utility tunnels to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated adjustable water supply support device for integrated utility tunnels, aiming to solve the problem that the support piers in the prior art cannot be flexibly adjusted in installation position according to pipeline installation requirements. The specific technical solution is as follows:

[0006] An integrated utility tunnel prefabricated adjustable water supply support device includes:

[0007] The sliding track includes a base plate and a web plate disposed on the base plate. The base plate is used to fix and connect to the base plate of the pipe gallery.

[0030] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Example:

[0033] See Figures 1-6 This embodiment provides a prefabricated adjustable water supply support device for integrated utility tunnels, including:

[0034] The sliding track 2 includes a base plate 2.1 and a web plate 2.2 disposed on the base plate 2.1. The base plate 2.1 and the web plate 2.2 form a T-shaped structure. The base plate 2.1 is used for fixed connection with the base plate of the pipe gallery. The web plate 2.2 is provided with a plurality of through holes 2.3. The number of sliding tracks 2 is N, and the sliding tracks 2 are arranged in parallel with each other, where N is a natural number greater than or equal to 2.

[0035] The water supply support 1 has at least two limiting slots 1.3 spaced apart along its own length (i.e., longitudinal direction) and N sliding grooves 1.2 parallel to each other at its bottom. The length direction of the limiting slots is parallel to the width direction of the water supply support, and the limiting slots are located within the height range of the sliding grooves. The water supply support 1 is set on the sliding track 2 and the web plate 2.2 is inserted into the sliding groove 1.2. The aligned limiting slots 1.3 and through holes 2.3 are penetrated by limiting members 5.

[0036] The limiting gasket 4 is used to fill the gap between the sliding groove 1.2 and the web 2.2.

[0037] Preferably, the limiting slot 1.3 can be a circular hole penetrating the width direction (i.e., transverse) of the water supply support, or it can be a semi-circular groove provided on the two end faces in the length direction of the water supply support. When the limiting slot 1.3 is a complete hole (e.g., a circular hole), the limiting slot cannot be provided on the end face of the water supply support. When the limiting slot is a groove (e.g., a semi-circular groove, a square groove), the limiting slot is provided on the end face of the water supply support. Further, the limiting member 5 can be a straight rod or a ring-shaped stirrup; when the limiting member is a straight rod, its two ends should be threaded, and it should be used with nuts to fix the limiting member to the water supply support.

[0038] See Figures 1-3 The web 2.2 is provided with multiple through holes 2.3 in a matrix along its height direction (i.e., vertical) and length direction (i.e., longitudinal). By changing the through holes 2.3 through which the limiting member 5 passes, the position of the water supply support can be adjusted in the vertical and longitudinal directions. By adjusting the thickness of the limiting gaskets on both sides of the web, the position of the water supply support can be adjusted in the transverse direction (i.e., along the width direction of the water supply support). Through the position adjustment in the vertical, longitudinal, and transverse directions, the water supply support 1 can adapt to the installation position requirements of the water supply pipeline.

[0039] Preferably, in this embodiment, the water supply support is provided with limiting slots 1.3 on both end faces in the length direction and on both end faces in the width direction, and the limiting slots 1.3 on the four end faces form a ring; the limiting member is a ring-shaped stirrup.

[0040] See Figure 2 The water supply support 1 is provided with multiple limiting slots 1.3 at intervals in its height direction. The longitudinal distance between two adjacent limiting slots 1.3 is an integer multiple of the longitudinal distance between adjacent through holes 1. The vertical distance between two adjacent limiting slots 1.3 is equal to an integer multiple of the vertical distance between adjacent through holes 1 (preferably one multiple in this embodiment, that is, the vertical distances of the two are equal), so that the water supply support 1 can be fixed on the sliding track 2 by multiple limiting members 5, thereby increasing the stability of the water supply support 1.

[0041] Furthermore, regardless of whether the limiting slot is a complete hole or a groove, multiple limiting slots can be spaced apart in the height direction of the water supply support 1 to increase the stability of the water supply support fixing; in this embodiment, the limiting slots 1.3 on the four end faces of the water supply support form annular grooves, that is, the water supply support is provided with multiple annular grooves spaced apart in the height direction, wherein a single annular groove ring is formed by the limiting slots 1.3 at the same height position on the four end faces.

[0042] See Figure 2 The water supply support 1 is provided with a receiving groove 1.1, which is used to place the water supply pipe; preferably, the receiving groove 1.1 is semi-circular, which can fit tightly against the water supply pipe and play a role in wrapping and supporting the water supply pipe. After the water supply pipe is installed in the receiving groove, it can be fastened with stirrups.

[0043] See Figure 1 and Figure 4The prefabricated adjustable water supply support device for the integrated utility tunnel also includes a fixed embedded part 3. The fixed embedded part 3 includes an embedded base plate 3.2 and an embedded screw 3.1 welded to the embedded base plate 3.2. The base plate 2.1 is provided with a through hole 2.4. The embedded base plate 3.2 is fixedly connected to the reinforcing steel of the utility tunnel base plate (preferably by welding). The embedded base plate 3.2 and the embedded screw 3.1 are embedded in the concrete during the construction of the utility tunnel base plate. After the embedded screw 3.1 passes through the through hole 2.4, the base plate 2.1 is locked with a nut.

[0044] Furthermore, there are multiple pre-embedded screws 3.1 and through holes 2.4. The spacing between adjacent pre-embedded screws 3.1 is equal to the spacing between adjacent through holes 2.4. This allows for adjustment of the installation position of the sliding track 2, enabling greater adjustment of the position of the water supply support. This adjustment refers to lateral and / or longitudinal position adjustment.

[0045] See Figure 5 The limiting gasket 4 has an opening slit 4.1. The limiting gasket 4 is sleeved on the limiting member 5. The limiting gasket limits the lateral movement of the water supply support. The opening slit 4.1 is used to allow the limiting gasket 4 to be locked onto the limiting member 5. The limiting gasket 4 is preferably made of rubber.

[0046] Furthermore, foam material is filled in the gap between the sliding groove 1.2 and the web 2.2 where no limiting gasket 4 is provided, to further fix the water supply support 1.

[0047] See Figure 6 A protective layer 1.4 is provided between the limiting slot 1.3 and the limiting member 5. The protective layer 1.4 prevents rigid contact between the limiting slot 1.3 and the limiting member 5, thus preventing damage to the water supply support pier, which is made of concrete, due to rigid contact with the limiting member. Preferably, in this embodiment, the protective layer is embedded in the limiting slot 1.3 to achieve the effect of protecting the water supply support pier. In this structural form, the protective layer can be made of rigid or flexible material. In some embodiments, the protective layer 1.4 may also be sleeved on the limiting member 5. In this structural form, the protective layer 1.4 is generally made of flexible material, such as silicone or rubber.

[0048] The technical solution applied in this embodiment is as follows:

[0049] The fixed embedded part 3 is welded to the bottom plate reinforcement of the pipe gallery, and is embedded in the concrete of the bottom plate of the pipe gallery, with only the embedded screw 3.1 exposed.

[0050] After the main construction of the utility tunnel is completed, the sliding track 2 is installed in a suitable position, wherein the pre-embedded screw 3.1 passes through the through hole 2.4 and is then tightened with a nut;

[0051] The water supply support 1 is installed on the sliding rail 2 to support the water supply pipeline. The web plate is inserted into the sliding groove 1.2. The water supply support is fixed on the sliding rail 2 by the limiting member 5. The limiting gasket 4 is set in the gap between the sliding groove 1.2 and the web plate 2.2. The gap between the sliding groove 1.2 and the web plate 2.2 without the limiting gasket 4 is filled with foam material.

[0052] The installation process involves adjusting the vertical, longitudinal, and lateral positions of the water supply support to prevent interference between the support and the water supply pipeline, ensuring proper support. During installation, a pin can be inserted through a hole in the web plate and secured in the limiting slot 1.3 for temporary fixation (or temporary support using jacks or similar devices). The required vertical and longitudinal displacement of the support is observed. After adjusting the support to the correct vertical and longitudinal positions, the limiting piece 5 is used for final fixation. Finally, the thickness of the limiting shims on both sides of the web plate is adjusted to fine-tune the lateral position, completing the installation of the water supply support.

[0053] The effect of applying the technical solution of this embodiment is:

[0054] The support device in this embodiment has a simple structure and is easy to construct. The vertical, longitudinal, and lateral positions of the water supply support can be freely adjusted according to the installation of the water supply pipeline, so that the receiving groove at the top of the water supply support fits tightly with the water supply pipeline, making the water supply pipeline more reasonably stressed and reducing the deformation of the water supply pipeline. At the same time, the device adopts a prefabricated structure, which is widely applicable, green and low-carbon, and simple to install and manage and maintain.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
