Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for underground utility tunnels, specifically to an integrated underground utility tunnel for urban planning. Background Technology

[0002] Underground urban pipeline corridors are tunnel spaces built underground in cities to integrate various engineering pipelines such as electricity, communications, gas, heating, and water supply and drainage. They are equipped with dedicated hoisting ports and monitoring systems, and are subject to unified planning, design, construction and management. They are important infrastructure and lifelines for ensuring the operation of cities. They are municipal facilities built underground in cities for laying municipal utility pipelines, and are subject to unified planning, design, construction and maintenance.

[0003] Existing underground utility tunnels typically have multiple separate functional areas for laying various cables and pipes. In the design of the cable functional areas, the current method of supporting and constraining cables is to place them on flat support bases and then use tools such as pipe clamps to fix the cables to the support bases. This results in the following problems: firstly, fixing multiple parallel cables is time-consuming; secondly, when a cable fails near the support base and needs maintenance, the location of the fault cannot be easily exposed because the position of the support base cannot be changed and the cable is supported on the support base, making maintenance difficult and causing great inconvenience to the maintenance work. Utility Model Content

[0004] The purpose of this utility model is to provide an urban planning underground integrated utility tunnel to solve the above-mentioned problems. By using the sliding cooperation between the support seat and the U-shaped bracket of the cable support component and the longitudinal sliding cooperation between the limiting rod and the limiting hole, the support seat can be detachably and horizontally assembled on the side of the utility tunnel body. At the same time, the support seat can be vertically slid down and separated from the U-shaped bracket simply by making the limiting rod longitudinally disengage from the limiting hole. This allows the support seat to be removed from the side of the utility tunnel body. The assembly and disassembly of the support seat on the side of the utility tunnel body is simple and easy to implement, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides an underground integrated utility tunnel for urban planning, including a tunnel body. Multiple mounting base plates are vertically fixedly installed on the inner walls of both sides of the tunnel body. Multiple layers of cable support assemblies with quick disassembly and assembly functions are assembled on the mounting base plates on both sides. The cable support assemblies on both sides are horizontally aligned at each layer.

[0007] The top of each cable support assembly is equipped with a cable constraint assembly with a separation function, which is used to separate and constrain multiple cables side by side.

[0008] Preferably, each cable support assembly includes a U-shaped bracket and a support base. Multiple U-shaped brackets are fixed to the opposite end faces of the mounting bases on both sides, and the cross-sectional shape of each U-shaped bracket along its longitudinal vertical plane is an inverted U-shape. Each support base is horizontally positioned, and the cable constraint assembly is mounted on its top surface. Simultaneously, the ends of the support bases on both sides that are far apart from each other are slidably inserted into the corresponding U-shaped brackets. Each support base has a longitudinally extending limit hole in the portion located within the U-shaped bracket. Each U-shaped bracket has a longitudinally extending mounting hole in the front. These mounting holes are through holes and longitudinally coaxial with the corresponding limit holes. Furthermore, each set of coaxially aligned mounting holes and limit holes is coaxially and detachably fitted with a limit rod.

[0009] Preferably, each of the limiting rods extending out of the mounting hole has a handle coaxially fixed to its front end.

[0010] Preferably, the limiting rods are all studs, the mounting holes and the limiting holes are all threaded holes, and the limiting rods are coaxially and detachably connected to the mounting holes and the limiting holes by means of threaded engagement.

[0011] Preferably, the limiting rod and the corresponding mounting hole and the limiting hole are coaxially slidably engaged, and the portion of the limiting rod located between the front of the corresponding handle and the U-shaped card seat is coaxially fitted with a spring, and the two ends of the spring are respectively fixedly connected to the corresponding handle and the U-shaped card seat.

[0012] Preferably, each of the cable constraint components includes a cable constraint seat and a cable guide groove. The top surface of each support seat is vertically fixed with the cable constraint seat along the horizontal direction. The top surface of each cable constraint seat is vertically provided with multiple cable guide grooves. The cable guide grooves are all through grooves in the vertical direction, and the multiple cable guide grooves of the same cable constraint seat are arranged side by side in the horizontal direction.

[0013] Preferably, a through slot is provided between the two sides of the top surface of the cable restraint seat in a transverse direction, and the through slot is connected to the cable guide groove in the transverse direction. The through slot is slidably inserted with a through screw, and the ends of the through screw extending out from the corresponding two sides of the cable restraint seat are coaxially engaged with a locking nut that can be pressed against the side surface of the cable restraint seat.

[0014] Preferably, the portion of the threaded screw between the locking nut and the cable constraint seat is coaxially slidably fitted with a washer to prevent loosening.

[0015] Preferably, each of the wire guide grooves is divided into two parts vertically, with the upper and lower parts being a rectangular straight groove and an arc-shaped groove, respectively. At the same time, the bottom of the through slot is not higher than the bottom of the upper part of the wire guide groove.

[0016] The aforementioned urban planning underground integrated utility tunnel, specifically the tunnel body, features multi-layered cable support assemblies on both sides. These cable support assemblies are designed for quick assembly and disassembly. The support base can be detachably and horizontally assembled on the side of the tunnel body via a sliding engagement between the support base and the U-shaped bracket, and a longitudinal sliding engagement between the limiting rod and the limiting hole. Furthermore, the support base can be vertically slid down and separated from the U-shaped bracket simply by disengaging the limiting rod longitudinally from the limiting hole, thus detaching it from the side of the tunnel body. This simple and easy assembly and disassembly method facilitates the quick assembly of the support base on the side of the tunnel body for cable support, and also makes subsequent assembly and disassembly easier. After the support is quickly removed from under the cable, the location of the cable fault is easily exposed, which facilitates the inspection and maintenance of the cable. Since the cable constraint component is assembled on the top of the support base of the cable support assembly, and the cable constraint component has a separation function, multiple cables can pass through and be separated by the multiple parallel cable slots of the cable constraint base. At the same time, the insertion screw passes horizontally through the through slot and is tightened at both ends by the locking nuts on both sides of the cable constraint base, which can restrict the cables passing through the through slots to prevent them from coming out or moving around. The constraint and fixing method for multiple cables is simple and easy to implement. This facilitates the quick constraint and fixing of multiple parallel cables, and also makes it easy to remove the insertion screw and allow the support base to slide vertically and separate from the U-shaped bracket.

[0017] The beneficial effects are as follows: 1. This utility model has multi-layered cable support components on both sides of the pipe gallery body, and the cable support components have a quick assembly and disassembly function. Then, by sliding the support seat and U-shaped card seat of the cable support component and sliding the limiting rod and limiting hole longitudinally, the support seat can be detachably and horizontally assembled on the side of the pipe gallery body. At the same time, only by making the limiting rod longitudinally disengage from the limiting hole can the support seat slide vertically down and separate from the U-shaped card seat, so that the support seat can be removed from the side of the pipe gallery body. The assembly and disassembly of the support seat on the side of the pipe gallery body is simple and easy to achieve. It is convenient to quickly assemble the support seat on the side of the pipe gallery body for cable support, and it is also convenient to quickly remove the support seat from under the cable to expose the cable fault location, which is conducive to the inspection and maintenance of the cable.

[0018] 2. The top of the support base of the cable support assembly is equipped with a cable constraint component, which has a separation function. Multiple cables can pass through the cable constraint base through multiple parallel cable slots and be separated. At the same time, the insertion screw passes horizontally through the through slot and is tightened at both ends by locking nuts on both sides of the cable constraint base. This restricts the cables passing through the through slots and prevents them from coming out or moving around. The constraint and fixing method for multiple cables is simple and easy to implement. This facilitates the quick constraint and fixing of multiple parallel cables and makes it easy to remove the insertion screw and allow the support base to slide vertically and separate from the U-shaped bracket.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-7 As shown, this utility model provides an underground integrated utility tunnel for urban planning, including a tunnel body 1. Multiple mounting base plates 2 are vertically fixedly installed on the inner walls of both sides of the tunnel body 1. Multiple layers of cable support assemblies 3 with quick-release and disassembly functions are assembled on the mounting base plates 2 on both sides. Each layer of the cable support assemblies 3 on both sides is horizontally aligned. Specifically, each cable support assembly 3 includes a U-shaped bracket 301 and a support base 304. Multiple U-shaped brackets 301 are fixed to the opposite end faces of the mounting base plates 2 on both sides, and the cross-sectional shape of the U-shaped brackets 301 along the longitudinal vertical plane is an inverted U-shape. The support bases 304 are horizontally arranged, and cable restraint components 4 are assembled on their top surfaces. Simultaneously, the ends of the support bases 304 on both sides that are far apart from each other are slidably inserted into the corresponding U-shaped brackets 301. The front of the support base 304 is located inside the U-shaped bracket 301. Each U-shaped bracket 301 has longitudinally spaced limiting holes 307 and longitudinally spaced mounting holes 305 on its front side. The mounting holes 305 are all through holes and are longitudinally coaxially aligned with the corresponding limiting holes 307. At the same time, each set of coaxially aligned mounting holes 305 and limiting holes 307 are coaxially and detachably inserted with limiting rods 306. The purpose of this arrangement is that the support base 304 of the cable support assembly 3 can be detachably and horizontally assembled on the side of the pipe rack body 1 by slidingly engaging the support base 304 of the cable support assembly 3 with the U-shaped bracket 301 and longitudinally sliding the limiting rods 306 with the limiting holes 307. At the same time, the support base 304 can be vertically slid down and separated from the U-shaped bracket 301 by simply disengaging the limiting rods 306 longitudinally from the limiting holes 307. This allows the support base 304 to be removed from the side of the pipe rack body 1. The assembly and disassembly of the support base 304 on the side of the pipe rack body 1 is simple and easy to implement.

[0031] See Figures 1-6As shown, each cable support assembly 3 has a cable constraint assembly 4 with a separating function installed on its top. This cable constraint assembly 4 is used to separate and constrain multiple cables side-by-side. Specifically, each cable constraint assembly 4 includes a cable constraint seat 401 and a cable passage groove 402. The top surface of each support seat 304 is vertically fixed with a cable constraint seat 401. Multiple cable passage grooves 402 are vertically formed on the top surface of each cable constraint seat 401. These grooves are all through grooves in the longitudinal direction, and multiple cable passage grooves 402 on the same cable constraint seat 401 are arranged horizontally side-by-side. A through slot 403 is formed horizontally between the two sides of the top surface of the cable constraint seat 401, and the through slot 403 is horizontally aligned with the cable passage groove 402. In this connection, the through slot 403 is horizontally inserted with a through screw 404 in a sliding fit. The ends of the through screw 404 extending out of the corresponding cable constraint seat 401 on both sides are coaxially engaged with locking nuts 406 that can be pressed against the side surface of the cable constraint seat 401. The purpose of this arrangement is that multiple cable guide slots 402 arranged side by side in the cable constraint seat 401 can allow multiple cables to pass through and be separated. At the same time, the through screw 404 passing horizontally through the through slot 403 and being pressed against both sides of the cable constraint seat 401 by locking nuts 406 at both ends can restrict the cables passing through the cable guide slots 402 to be confined in the cable guide slots 402 and prevent them from coming out or moving around. The method of constraining and fixing multiple cables is simple and easy to implement.

[0032] See Figures 1-7 As shown, the cable support assembly 3 and the cable constraint assembly 4 have been optimized as follows. Specifically, for the cable support assembly 3, the front end of each limiting rod 306 extending from the mounting hole 305 is coaxially fixed with a handle 302, so that the combination and disassembly process of the limiting rod 306 and the limiting hole 307 can be operated by applying force by holding the handle 302. Optionally, the limiting rods 306 are all studs, and the mounting hole 305 and the limiting hole 307 are all threaded holes. The limiting rods 306 are coaxially and detachably connected to the mounting hole 305 and the limiting hole 307 by threaded engagement. This setting facilitates the rapid combination and disassembly of the limiting rods 306, the limiting holes 307, and the mounting hole 305 by turning the limiting rods 306. Alternatively, the limiting rod 306 can be coaxially slidably engaged with the corresponding mounting hole 305 and the limiting hole 307. The portion of the limiting rod 306 located between the corresponding handle 302 and the front of the U-shaped bracket 301 is coaxially fitted with a spring 303, and the two ends of the spring 303 are fixedly connected to the corresponding handle 302 and the U-shaped bracket 301 respectively. This arrangement facilitates the quick disassembly and assembly of the limiting rod 306 with the limiting hole 307 and the mounting hole 305 by pulling or releasing the limiting rod 306.

[0033] See Figures 1-6As shown, specifically in the cable constraint assembly 4, the portion of the threading screw 404 between the corresponding locking nut 406 and the cable constraint seat 401 is coaxially slidably fitted with a washer 405 to prevent loosening. This arrangement facilitates the anti-loosening design after the locking nut 406 is tightened by pressing the washer 405 against the locking nut 406, ensuring that the threading screw 404 can constrain and fix multiple parallel cables to their respective cable guide grooves 402. Alternatively, the cable trays 402 are vertically divided into two parts, with the upper and lower parts being a rectangular straight tray and an arc-shaped tray, respectively. At the same time, the bottom of the through slot 403 is not higher than the bottom of the upper part of the cable tray 402. This arrangement firstly facilitates the bottom of the cable to be more closely supported by the bottom of the cable tray 402 when the cable passes through it. Secondly, it facilitates the insertion screw 404 to descend along the through slot 403 to the bottom of the outer perimeter and press down on the top of the outer perimeter of the cable when it is horizontally placed, thereby improving the stability of the cable by the insertion screw 404.

[0034] Using the above structure, specifically for the pipe rack body 1, since multiple layers of cable support assemblies 3 are provided on both sides of the pipe rack body 1, and the cable support assemblies 3 have a quick assembly and disassembly function, the support seat 304 can be detachably and horizontally assembled on the side of the pipe rack body 1 by slidingly engaging the support seat 304 with the U-shaped bracket 301 and longitudinally engaging the limiting rod 306 with the limiting hole 307. Simultaneously, the support seat 304 can be vertically slid down and separated from the U-shaped bracket 301 simply by longitudinally disengaging the limiting rod 306 from the limiting hole 307, thus detaching the support seat 304 from the side of the pipe rack body 1. The assembly and disassembly of the support seat 304 on the side of the pipe rack body 1 is simple and easy to implement, facilitating both quick assembly of the support seat 304 on the side of the pipe rack body 1 for cable support and subsequent quick removal of the support seat 304 from the cable. The cable fault location is easily exposed when the cable support is positioned below, facilitating cable inspection and maintenance. Since the cable support assembly 3's support base 304 is equipped with cable constraint components 4 on its top, and these components have a separating function, multiple parallel cable grooves 402 on the cable constraint base 401 allow multiple cables to pass through and be separated. Simultaneously, the insertion screw 404 passes laterally through the through slot 403, and locking nuts 406 are installed at both ends to press it against both sides of the cable constraint base 401, thus restricting the cables passing through the through slots 402 and preventing them from escaping or moving. This method of constraining and fixing multiple cables is simple and easy to implement, facilitating quick and easy constraint and fixing of multiple parallel cables. It also allows the support base 304 to slide vertically and separate from the U-shaped bracket 301 after the insertion screw 404 is removed.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
