Description

Technical Field

[0001] This invention relates to the field of pipe laying, specifically to a trenchless pipe laying structure. Background Technology

[0002] In trenchless pipe laying, annular gaps will exist between the pipe and the surrounding soil after the pipe is laid. To enhance the stability of the pipe, prevent ground settlement, and improve the overall quality of the project, these gaps need to be filled with grout. Currently, there are two common grouting techniques: one is to drill holes at the ground surface location corresponding to the pipe axis and inject grout into the gaps through the drilled channels; the other is to directly insert the grouting pipe into the gap between the pipe and the soil for grouting.

[0003] However, the first method requires drilling on the ground, which not only occupies roads and disrupts traffic, but also violates the core advantage of trenchless technology in minimizing ground damage and occupation. Although the second method avoids ground excavation, in actual operation, it is difficult to accurately and completely insert the grouting pipe into the predetermined depth and position, which easily leads to problems such as discontinuous grouting and incomplete filling, seriously affecting the grouting quality and project reliability. Therefore, there is an urgent need for a new type of grouting structure that can take into account the advantages of trenchless construction, the convenience of grouting operation and the reliability of filling effect to make up for the above defects. Summary of the Invention

[0004] This application provides a trenchless drag pipe structure that enables continuous, efficient, and uniform grouting into the soil pores of the pipeline. It is simple and convenient to install, can be reused, and does not require additional drilling in the ground. The presence or absence of obstacles on the ground does not affect the grouting operation, which greatly saves construction time and economic costs and meets the basic requirements of trenchless technology in terms of economy and environmental protection.

[0005] In a first aspect, embodiments of this application provide a trenchless pipe-draft structure, comprising:

[0006] The main body of the towing pipe;

[0007] Grouting pipe, wherein multiple grouting holes are provided on the grouting pipe;

[0008] The mounting component includes a fixing block disposed on the towing pipe body, and the fixing block is provided with a slot.

[0009] A connector, comprising a sealing block disposed on a grouting pipe, the sealing block having an area larger than the area of ​​a slot port, and a locking block extending into the slot on the sealing block.

[0010] In conjunction with the first aspect, in one embodiment, the mounting component further includes two arc-shaped locking blocks rotatably mounted together, with a positioning block provided at one opposite end of the two arc-shaped locking blocks, and the two arc-shaped locking blocks being fixed to the drag tube body by screws, with the fixing block disposed on the arc-shaped locking blocks.

[0011] In conjunction with the first aspect, in one embodiment, the arc-shaped card block is provided with multiple fixing blocks.

[0012] In conjunction with the first aspect, in one embodiment, the slot includes a mating interface formed on a fixing block and a mating groove communicating with and extending inward from the mating interface, wherein the area of ​​the sealing block is larger than the area of ​​the mating interface.

[0013] In conjunction with the first aspect, in one embodiment, the locking block includes an extension block disposed on the sealing block and a limiting block located at the end of the extension block.

[0014] In conjunction with the first aspect, in one embodiment, the limiting block is an elastic arc-shaped block.

[0015] In conjunction with the first aspect, in one embodiment, the two ends of the limiting block abut against the inner wall of the interface.

[0016] In conjunction with the first aspect, in one embodiment, the inner wall of the interface near the arc surface of the limiting block is inclined.

[0017] In conjunction with the first aspect, in one embodiment, the end of the sealing block near the fixing block is in close contact with the end of the fixing block away from the arc-shaped locking block.

[0018] In conjunction with the first aspect, in one embodiment, the grouting pipe is provided with a clamp, and the sealing block is disposed on the clamp.

[0019] The beneficial effects of the technical solutions provided in this application include:

[0020] 1. This trenchless tow pipe structure has an additional grouting pipe on the tow pipe with multiple grouting holes. This allows the grouting pipe to be laid synchronously with the tow pipe body, and the grouting work can be carried out simultaneously with the construction of the tow pipe. There is no need to drill additional holes in the ground, and the presence or absence of obstacles on the ground will not affect the grouting operation. This greatly saves construction time and economic costs, and meets the basic requirements of trenchless technology in terms of economy and environmental protection.

[0021] 2. This trenchless towing pipe structure, through the designed connectors and mounting components, allows for easy installation by simply inserting the connectors into the mounting components to fix the grouting pipe to the towing pipe body. This greatly improves the convenience of on-site installation and thus enhances the overall construction efficiency. Furthermore, after installation, the contact surfaces of the connectors and mounting components fit tightly together, preventing mud from entering the mounting components and increasing the resistance of the grouting pipe's advance, which could lead to detachment.

[0022] 3. This trenchless towing pipe structure, through the setting of arc-shaped clamps and screws, allows the structure to be adapted to towing pipes of different sizes. Furthermore, the arc-shaped clamps are equipped with multiple fixing blocks, so that grouting pipes can be installed in different directions, further improving the uniformity of grouting and ensuring the grouting effect.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0032] Please see Figure 1 This application provides a trenchless pipe-drawing structure, including:

[0033] Pull pipe body 1;

[0034] Grouting pipe 2 is used for grouting operations to fill the gap between the drag pipe and the soil. In this embodiment, grouting pipe 2 is preferably a PVC pipe, which has low production cost and can effectively reduce the cost of the entire construction period.

[0035] like Figure 2 As shown, the grouting pipe 2 has multiple grouting holes 3, which allows the grout to flow out evenly;

[0036] An additional grouting pipe 2 is installed on the towing pipe body 1, with multiple grouting holes 3. This allows the grouting pipe 2 to be laid synchronously with the towing pipe body 1, and grouting work to be carried out simultaneously with the construction of the towing pipe body 1. There is no need to drill additional holes on the ground, and the presence or absence of obstacles on the ground does not affect the grouting operation, which greatly saves construction time and economic costs, and meets the basic requirements of trenchless technology in terms of economy and environmental protection.

[0037] Mounting component 5, which includes a fixing block 501 disposed on the drag tube body 1, and the fixing block 501 is provided with a slot;

[0038] Specifically, such as Figure 3 and Figure 5 As shown, the slot includes a docking interface 502 formed on the fixing block 501 and a mating groove 503 that communicates with the docking interface 502 and extends inward.

[0039] The connector 7 includes a sealing block 701 disposed on the grouting pipe 2. The area of ​​the sealing block 701 is larger than the area of ​​the slot port. The sealing block 701 is provided with a locking block extending into the slot. The locking block includes an extension block 702 disposed on the sealing block 701 and a limiting block 703 located at the end of the extension block 702.

[0040] Among them, the limiting block 703 is an elastic arc-shaped block; please refer to [link / reference needed]. Figure 4When installing the grouting pipe 2 onto the towing pipe body 1 at the construction site, it is only necessary to insert the limiting block 703 into the docking groove 503. During the process of the arc surface of the limiting block 703 contacting the docking interface 502, the two arc surfaces of the limiting block 703 will undergo elastic deformation and bend towards the side closer to the extension block 702 until the limiting block 703 is completely inserted into the docking groove 503, thereby realizing the installation of the grouting pipe 2. The operation is simple and convenient, greatly improving the convenience of on-site installation and thus improving the overall construction efficiency.

[0041] In this embodiment, the area of ​​the sealing block 701 is larger than the area of ​​the interface 502. The end of the sealing block 701 near the fixing block 501 is in close contact with the end of the fixing block 501 away from the arc-shaped locking block 4. The two ends of the limiting block 703 abut against the inner wall of the interface 502.

[0042] As described above, after the grouting pipe 2 is connected to the towing pipe body 1, the end face of the sealing block 701 will fit tightly against the end face of the interface 502. This can prevent mud from entering the docking groove 503, thus increasing the resistance of the grouting pipe 2 and preventing the grouting pipe 2 from accidentally falling off during the movement. This improves the stability of the grouting pipe 2 during construction. The two ends of the limiting block 703 abut against the inner wall of the interface 502, making the limiting block 703 less prone to loosening after connection, further improving the overall structural stability.

[0043] In addition, such as Figure 3 As shown, both sides of the fixing block 501 and the sealing block 701 in the horizontal direction are set with slopes, which can further reduce the resistance of the grouting pipe 2 when it moves.

[0044] In this embodiment, the mounting component 5 also includes two arc-shaped locking blocks 4 that are rotatably mounted together. The two arc-shaped locking blocks 4 are provided with positioning blocks 8 at opposite ends. The two arc-shaped locking blocks 4 are fixed to the drag tube body 1 by screws. Fixing blocks 501 are provided on the arc-shaped locking blocks 4. Multiple fixing blocks 501 are provided on the arc-shaped locking blocks 4.

[0045] Among them, such as Figure 2 As shown, the structure can be adapted to different sizes of towing pipes by means of the arc-shaped locking block 4 and the screw, which improves the practicality of the structure. In addition, the arc-shaped locking block 4 is provided with multiple fixing blocks 501, so that the grouting pipe 2 can be installed in different directions, which further improves the uniformity of grouting and ensures the grouting effect.

[0046] In addition, the two opposing arc-shaped locking blocks 4 also facilitate their disassembly and installation with the towing pipe body 1.

[0047] In this embodiment, the inner wall of the interface 502 near the arc surface of the limiting block 703 is inclined.

[0048] Please see Figure 4 Its tilt angle is adapted to the direction of the two arc surfaces of the limiting block 703. The thrust of the inclined surface can more smoothly squeeze the two inclined surfaces of the limiting block 703 so that they undergo relative elastic deformation, thereby improving the smoothness of the limiting block 703 when it is inserted into the docking groove 503.

[0049] In this embodiment, the grouting pipe 2 is provided with a clamp 6, and the sealing block 701 is set on the clamp 6. The clamp 6 is an elastic clamp in the prior art, and its two ends are fixed by bolts, which makes it convenient to fix the grouting pipe 2 on the towing pipe body 1. When installing a new grouting pipe 2, it is only necessary to install the corresponding clamp 6 on it.
