Description

Technical Field

[0001] The utility model relates to a tunnel pipeline, in particular to a tunnel pipeline quick fixing device. Background Art

[0002] The existing support type of underground engineering tunnel pipelines (water supply pipes, air supply pipes, drainage pipes) is currently mainly welded into a "ㅕ" shape with angle steel, anchored with the tunnel primary support or secondary lining side wall through expansion bolts, and the pipeline is placed on the horizontal angle steel and fixed with a "U"-shaped buckle. The existing structure has many disadvantages such as a lot of preliminary preparation work such as material cutting and welding, a large workload of drilling and anchoring, and slow on-site construction progress, which is not suitable for the requirements of modern tunnel rapid construction. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a tunnel pipeline quick fixing device, which can improve the tunnel pipeline installation efficiency.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A tunnel pipeline quick fixing device, comprising a bracket and a limit assembly;

[0006] The bracket includes a vertical connecting rod, one side of which is fixed to the concrete by an expansion bolt, and the other side of which is provided with a plurality of groups of horizontal rods at intervals along the length direction, and a plurality of groups of strip-shaped pin holes are provided on the horizontal rods along the length direction;

[0007] The limiting assembly comprises a sleeve, which is sleeved with the horizontal rod and locked by a wedge-shaped latch pin, and an L-shaped locking rod is installed on the upper end of the sleeve, which limits and fixes the functional pipeline.

[0008] The vertical connecting rod is made of angle steel.

[0009] The horizontal rod is made of rectangular steel and the strip-shaped pin holes on the horizontal rod are staggered and arranged in two rows.

[0010] The sleeve and the L-shaped locking rod are connected and reinforced by oblique ribs.

[0011] The utility model provides a tunnel pipeline quick fixing device, which has the following technical effects:

[0012] 1) Since the bracket and limit assembly can be pre-processed in the factory, and the assembly can be realized on site by simply inserting the wedge-shaped pins, compared with the existing angle steel welded horizontal bracket and the "U"-shaped buckle bolt fastened bracket structure, it solves the shortcomings of the existing pipeline bracket such as complex construction process, many connecting bolts, many on-site operations and slow construction progress; it speeds up the pipeline installation construction progress, improves work efficiency, saves construction costs, and produces significant benefits in the installation and construction of underground engineering tunnel pipelines.

[0013] 2) The number of horizontal rods can be determined according to the number of functional pipes, and since the strip pin holes are staggered in two rows, wedge pins can be inserted into the corresponding strip pin holes according to functional pipes of different diameters to ensure that various functional pipes can be limited and fixed.

DETAILED DESCRIPTION

[0019] like Figure 1-2 As shown, a tunnel pipeline quick fixing device includes a bracket and a limiting component.

[0020] The bracket includes a vertical connecting rod 1, which is made of angle steel with a size of 900mm×80mm×6mm. The vertical connecting rod 1 has multiple holes, which can be fixed to the concrete 11 by expansion bolts 2. Multiple groups of horizontal rods 3 are fixed on one side of the vertical connecting rod 1. The horizontal rods 3 are made of rectangular steel with a cross-sectional size of 80mm×40mm×2mm, and the length is determined according to the diameter of the on-site pipeline. Each group of horizontal rods 3 has multiple strip-shaped pin holes 6 vertically opened along the length direction.

[0021] The limit assembly includes a locking rod 4, which is L-shaped, with a cross-sectional size of 82mm×42mm×2mm and a length of 100mm. A sleeve 13 is fixed to the lower end of the locking rod 4, and the sleeve 13 is made of rectangular steel. An oblique rib 14 is fixed between the L-shaped locking rod 4 and the sleeve 13, and a strip-shaped pin hole 6 is also opened on the sleeve 13. During installation, the sleeve 13 is inserted into the horizontal rod 3, and the strip-shaped pin holes 6 of the two are aligned. The wedge-shaped pin 5 can fix the limit assembly after insertion. The locking rod 4, the horizontal rod 3 and the vertical connecting rod 1 can form a limit fixation for the pipeline. There are mainly three types of pipelines here: water supply pipe 7, drainage pipe 8, and air supply pipe 9, which can be arranged up and down on this device respectively.

[0022] Working principle and process:

[0023] 1) According to the tunnel excavation section size and construction plan, determine the diameters of functional pipes such as water supply pipe 7, drainage pipe 8, air supply pipe 9, etc., design the pipe support according to the parameters of the functional pipes during the tunnel construction period, and further determine the design dimensions of the vertical connecting rod 1, horizontal rod 3 and locking rod 4.

[0024] 2) The processing plant outside the tunnel carries out standardized processing according to the design dimensions, performs cutting, grinding, drilling and welding operations according to standard parts, welds the vertical connecting rod 1 and the horizontal rod 3 into an integral part of the bracket, and processes the locking rod 4, the sleeve 13 and the oblique rib 14 into an assembly.

[0025] 3) Then transport it to the site, and perform impact drilling and hole making operations every 6m. The center height of the bracket installation is generally 1.0m above the tunnel bottom plate. The bracket as a whole is fixed by expansion bolts 2. The functional pipeline is placed on the horizontal rod 3. Then, the limit assembly is installed at a suitable position outside the functional pipeline, and the wedge-shaped pin 5 is inserted. The wedge-shaped pin 5 is knocked down by a hammer. The locking rod 4 and the vertical connecting rod 1 work together to lock and fix the pipeline, realizing rapid assembly construction and greatly improving the construction speed of on-site pipeline fixation.
