Description

Technical Field

[0001] This utility model relates to a fixing device, specifically a drainage pipe fixing device, belonging to the technical field of drainage equipment for tunnel engineering. Background Technology

[0002] The tunnel drainage system is one of the core infrastructures ensuring the structural safety and stable passage of tunnels. Transverse drainage pipes, as a key component of the drainage system, directly determine the effectiveness and durability of the drainage function through their installation and fixing quality. Currently, in tunnel construction, the fixing methods for transverse drainage pipes still mainly rely on traditional techniques, commonly using wire binding or simple pipe clamps for fixation.

[0003] However, these traditional fixing methods have many inherent defects and are difficult to adapt to the complex operating environment inside tunnels. In terms of fixing performance, the constraint of wire binding is prone to loosening over time, and the structural strength of simple pipe clamps is limited, resulting in poor stability of the drainage pipe. Under external forces such as tunnel structural settlement and vehicle vibration, problems such as drainage pipe displacement and loosening are easily encountered. More significantly, traditional fixing methods are clearly insufficient in terms of corrosion resistance and deformation resistance. Tunnels often have abundant groundwater and high humidity, and in some special geological areas, the groundwater contains corrosive media. Wire is prone to rust and breakage, and simple pipe clamps can also fail due to corrosion, failing to maintain the drainage pipe's fixing effect for a long time.

[0004] The aforementioned fixation issues not only reduce the drainage efficiency of the horizontal drainage pipes, but may also cause pipe damage, joint leakage, and other malfunctions, thereby affecting the stability of the tunnel structure and increasing the difficulty and cost of later maintenance.

[0005] Therefore, developing a stable and reliable drainage pipe fixing device is the key to solving the above-mentioned technical problems. Summary of the Invention

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] Example 1

[0054] As per the instruction manual Figures 1 to 10 As shown, a drain pipe fixing device includes:

[0055] Support rod 1;

[0056] Limiting component 2 is connected to both ends of the support rod 1 and is used to limit the connection of the support rod 1 to the invert arch steel bar 6.

[0057] Adjustable fasteners 3 are connected to support rods 1 and are used to fix drain pipes 5 of different sizes.

[0058] Furthermore, the support rod 1 is a fixed rod, wherein the support rod 1, the limiting member 2, and the adjustable fixing member 3 are all made of materials with strong corrosion resistance.

[0059] Furthermore, the limiting member 2 is composed of limiting blocks 21 symmetrically connected to both sides of the end of the support rod 1, forming a bayonet structure with one end open.

[0060] Specifically, the limiting block 21 is square, triangular, cylindrical, trapezoidal or spherical.

[0061] Preferably, the limiting block 21 is in the shape of a right trapezoid.

[0062] Furthermore, the adjustable fasteners 3 are fixedly connected to the support rod 1 at equal or unequal intervals.

[0063] Furthermore, the adjustable fixing member 3 includes:

[0064] Adjustment seat 31;

[0065] Adjusting rod 32 is rotatably connected to the upper part of adjusting seat 31;

[0066] The clamp toothed belt 33 has one end fixedly connected to one end of the bottom of the adjusting seat 31, and the other end bent through the adjusting groove of the adjusting seat 31.

[0067] The non-fixed end of the clamp toothed belt 33 is provided with a toothed hole section, and the thread on the adjusting rod 32 works in conjunction with the toothed hole section.

[0068] In this invention, the adjusting rod 32 drives the clamp toothed belt 33 to move, thereby gradually reducing the diameter of the clamp toothed belt 33 and thus clamping and fixing the drain pipe 5.

[0069] Specifically, one end of the adjusting rod 32 is provided with an adjusting groove or is connected to a butterfly-shaped toggle head.

[0070] In this utility model, the adjustment groove is cross-shaped or plum blossom-shaped. Specifically, one end of the adjustment rod 32 is provided with a cross-shaped recessed adjustment groove, which facilitates adjustment by tools; the butterfly-shaped toggle connected to one end of the adjustment rod 32 facilitates direct adjustment and locking by the operator, increasing ease of use.

[0071] Example 2

[0072] This embodiment is basically the same as embodiment 1, except that the support rod 1 is a telescopic rod, and the support rod 1 includes a fixed sleeve 11 and a movable rod 12 that is slidably engaged in the fixed sleeve 11.

[0073] In this embodiment, since the support rod 1 adopts a telescopic design, its length can be flexibly adjusted according to actual needs during installation inside the tunnel arch reinforcement, ensuring uniform distribution of support force and effectively adapting to the deformation and temperature changes of the tunnel structure. This design improves installation accuracy and construction efficiency, simplifies the adjustment process, reduces installation problems caused by unsuitable support rod lengths, enhances the stability of the overall structure, reduces safety risks caused by errors, and improves the adaptability and economy of the construction process.

[0074] Example 3

[0075] This embodiment is basically the same as embodiment 2, except that the adjustable fixing member 3 is connected to the support rod 1 at equal or unequal distances via the connecting ring 4.

[0076] Specifically, the connecting ring 4 is fixedly connected to the support rod 1, or the connecting ring 4 is slidably sleeved on the support rod 1.

[0077] In one embodiment, since the connecting ring 4 is slidably sleeved on the support rod 1, it can make a certain degree of displacement or adjustment to the adjustable fixing member connected thereto under certain circumstances, so that the fixing device can adapt to different changes in the installation of the invert arch reinforcement. Especially during tunnel construction, geological changes and external forces may cause certain deformation or displacement. The sliding connection helps to relieve these stresses and prevent destructive deformation.

[0078] In this embodiment, the support rod 1, the limiting member 2, the adjustable fixing member 3, and the connecting ring 4 are all made of highly corrosion-resistant materials, and their surfaces are also protected by an anti-corrosion coating.

[0079] In summary, a more specific embodiment of this utility model is as follows:

[0080] Before using this utility model, it needs to be installed as a backup.

[0081] The specific installation steps are as follows:

[0082] Step 1, Construction Preparation: First, thoroughly clean the construction site, remove debris, scum and other obstacles, and ensure that the work area is flat and clean; at the same time, count and prepare the required drainage pipe fixing devices, the horizontal drainage pipe 5 to be installed, and related installation tools such as binding wire and measuring tape, and check whether the specifications of the adjustable fixing parts 3 match the model of the drainage pipe 5 to avoid affecting the installation quality due to incompatible specifications.

[0083] Step 2: According to the installation requirements of the drainage pipe 5 in the tunnel construction design, extend and retract the length of the support rod 1 to the required position, and snap the limiting parts 2 at both ends of the support rod 1 onto the corresponding inverted arch steel bars 6. Then, fix the support rod 1 and the limiting parts 2 to the inverted arch steel bars 6 into a whole by spot welding.

[0084] Step 3: Move the position of the adjustable fastener 3. During this process, the horizontal position, vertical height and angle of the adjustable fastener 3 can be precisely adjusted by measuring tape to ensure that the central axis of multiple adjustable fasteners 3 is on the same straight line, laying the foundation for the smooth installation of the subsequent drainage pipe 5.

[0085] Step 4: After adjusting the positions of support rod 1 and adjustable fastener 3, they are initially secured by binding wire.

[0086] Step 5: After all support rods 1 and adjustable fasteners 3 are positioned and fixed, the invert arch concrete pouring construction is carried out. During the pouring process, care should be taken to avoid the area of ​​adjustable fasteners 3 to prevent the position of adjustable fasteners 3 from shifting due to concrete impact. At the same time, ensure that the bottom and surrounding concrete of adjustable fasteners 3 are filled densely and without voids or defects. After the invert arch concrete reaches the design requirements, the fixing ring will form a stable connection with the invert arch structure and complete the permanent fixation.

[0087] Step 6, Drainage pipe installation: After confirming that the adjustable fixing part 3 is securely fixed, slowly push the horizontal drainage pipe 5 from one side of the tunnel to the other side, passing through each of the preset adjustable fixing parts 3 in sequence. After the drainage pipe 5 is installed in place, adjust the tightness of the clamp toothed belt 33 and the drainage pipe 5 by adjusting the adjusting rod 32 to ensure that the drainage pipe 5 is securely connected to the adjustable fixing part 3.

[0088] Step 7: After each adjustable fastener 3 is adjusted, seal the gap between the adjustable fastener 3 and the drain pipe 5 as needed to further improve the fixing stability and complete the pipe installation and fixing work of this utility model.

[0089] Finally, it should be noted that the concept, specific structure, and technical effects of this utility model have been clearly and completely described above in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model.
