Description

Technical Field

[0001] This utility model relates to the field of pipe gallery engineering technology, specifically a novel pre-embedded sliding groove device for pipe gallery engineering. Background Technology

[0002] In utility tunnel projects, pre-embedded grooving devices are crucial components for securing various pipelines (such as cables, water pipes, and gas pipes). Existing pre-embedded grooving devices are typically integral structures with fixed lengths, leading to numerous inconveniences during transportation and installation. This is especially true in long utility tunnel projects, where the integral grooving device is difficult to transport and hard to adjust flexibly according to actual needs during installation.

[0003] Meanwhile, the structural stability of existing pre-embedded chute devices needs improvement. During long-term use, they are prone to deformation due to the weight of the pipeline and the influence of the external environment. In addition, the corrosion resistance of existing chute devices is insufficient, making them susceptible to corrosion in humid and other harsh environments, thus affecting their service life. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a novel pre-embedded sliding groove device for pipe gallery engineering. This device has a stable structure, is easy to install, and has good corrosion resistance, thus meeting the usage requirements of pipe gallery engineering.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A novel pre-embedded chute device for pipe gallery engineering includes several chute units, each of which is detachably connected by a connector. The chute unit has a U-shaped structure. Several mounting holes for installing pipeline fixing components are symmetrically arranged on both sides of the chute unit. Several fixing holes for fixing to the pipe gallery wall are arranged at the bottom of the chute unit. An anti-corrosion coating is provided on the outer surface of the chute unit. Reinforcing ribs are symmetrically arranged on both sides of the inner side of the chute unit. The reinforcing ribs extend along the length of the chute unit. The connector includes a connecting block and a fastening bolt. The two ends of the connecting block are respectively inserted into the inner side of the ends of two adjacent chute units. The connecting block is provided with a through hole that matches the mounting hole on the side wall of the chute unit. The fastening bolt passes through the mounting hole and the through hole to fix the connecting block to the chute unit.

[0008] Preferably, the anti-corrosion coating is an epoxy resin coating with a thickness of 0.1-0.3 mm. Epoxy resin coatings have excellent anti-corrosion properties and can effectively improve the service life of the chute device.

[0009] Preferably, the reinforcing rib and the sidewall of the slide unit are integrally formed. This integrally formed structure ensures the connection strength between the reinforcing rib and the slide unit, further improving the structural stability of the slide device.

[0010] Preferably, the fixing hole is provided with an internal thread for fixing with an expansion bolt. The sliding groove unit is fixed to the pipe gallery wall by the expansion bolt, ensuring a firm and reliable fixation.

[0011] Preferably, the chute unit is made of high-strength steel. The steel strength grade is not lower than Q345, and the high-strength steel can ensure that the chute device has sufficient load-bearing capacity to meet the requirements of pipeline fixing.

[0012] Preferably, the connecting block is made of the same material as the sliding unit. Using the same material ensures compatibility and connection strength between the connecting block and the sliding unit.

[0013] The beneficial effects of this utility model are:

[0014] This utility model adopts a segmented chute unit design, with each chute unit detachably connected by connectors, facilitating transportation and installation. The total length of the chute device can be flexibly adjusted according to the actual length of the pipe gallery project, improving installation flexibility. The outer surface of the chute unit is coated with an anti-corrosion layer, effectively improving the corrosion resistance of the chute device and extending its service life, making it particularly suitable for harsh environments such as humid conditions. Reinforcing ribs are integrated into the sidewalls of the chute unit, significantly improving the structural stability and load-bearing capacity of the chute device and preventing deformation during long-term use. The connectors have a simple structure and reliable connection, using connecting blocks and fastening bolts to fix adjacent chute units together, facilitating installation and disassembly, and simplifying future maintenance and replacement.
