Technical Field

[0001] This utility model belongs to the field of tunnel construction technology, and in particular relates to a tooling for splicing and fixing water pipes inside a tunnel. Background Technology

[0002] During TBM (Tunnel Boring Machine) construction, the installation of water pipe systems within the tunnel currently relies primarily on manual labor. Workers manually move, position, and connect pipes within the confined, damp tunnel space. This traditional manual method has significant drawbacks: firstly, the handling of water pipes (typically metal or heavy composite materials) is laborious, requires high positioning accuracy, and involves cumbersome connection steps, resulting in low overall installation efficiency, slow progress, and difficulty in meeting the logistical support demands of rapid construction; secondly, frequent handling of heavy objects and the use of manual tools for fastening connections greatly increase the risk of accidents such as falling objects, slips and falls, and mechanical injuries, posing a direct threat to the personal safety of construction workers. Therefore, the current manual installation of water pipes has become one of the key bottlenecks restricting construction efficiency and safety. Summary of the Invention

[0003] The technical problem this utility model aims to solve is to address the shortcomings of the existing technology by providing a tooling for splicing and fixing water pipes in tunnels. This tooling connects the positioning component on the installed water pipe and the guide component on the water pipe to be installed using an arc-shaped connecting rod. The installed water pipe is used to position and connect the water pipe to be installed, simplifying the connection process and improving positioning accuracy. Furthermore, the use of the positioning component, guide component, and arc-shaped connecting rod to connect the installed and water pipes avoids safety accidents such as being struck by objects, slipping and falling, or being pinched by machinery during manual handling, thus ensuring the personal safety of construction workers.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a water pipe splicing and fixing fixture in a tunnel, including a positioning component set on an installed water pipe, a guide component set on a water pipe to be installed, and a plurality of arc-shaped connecting rods connected between the positioning component and the guide component, one end of the arc-shaped connecting rod being fixedly connected to the positioning component, and the other end of the arc-shaped connecting rod being fixedly connected to the guide component;

The semi-circular plates in the two guide cards are spliced ​​together to form a cylindrical sleeve, and the inner diameter of the cylindrical sleeve is the same as the outer diameter of the water pipe to be installed.

[0007] Furthermore, the connecting plates on the same side of the two positioning cards are fastened together as one unit by positioning bolts, and the connecting plates on the same side of the two guide cards are fastened together as one unit by guide bolts. The connecting plate of the positioning card has a through hole for the positioning bolt to pass through, and the connecting plate of the guide card has a through hole for the guide bolt to pass through.

[0008] Furthermore, a rubber pad is provided between the semi-circular plate in the positioning card and the installed water pipe, and a rubber pad is provided between the semi-circular plate in the guide card and the water pipe to be installed.

[0009] Furthermore, one of the semicircular plates in the positioning card is integrally manufactured with the two connecting plates, and one of the semicircular plates in the guide card is integrally manufactured with the two connecting plates; one end of the arc-shaped connecting rod is fixed to one of the semicircular plates of the positioning card, and the other end of the arc-shaped connecting rod is fixed to the corresponding semicircular plate of the guide card.

[0010] The beneficial effects of this utility model are that it connects the positioning component on the installed water pipe and the guide component on the water pipe to be installed by means of an arc-shaped connecting rod, and uses the installed water pipe to connect and position the water pipe to be installed. The connection steps are simple and the positioning accuracy is improved. At the same time, the use of positioning components, guide components and arc-shaped connecting rods to connect the installed water pipe and the water pipe to be installed avoids safety accidents such as being hit by objects, slipping and falling, and being pinched by machinery during manual handling, thus ensuring the personal safety of construction personnel.

[0011] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

Both the positioning card 4 and the guide card 6 include a semi-circular plate 8 and two connecting plates symmetrically arranged on the left and right sides of the semi-circular plate 8. The semi-circular plate 8 is formed by bending a rectangular flat plate, and the connecting plates are rectangular strips with the same length as the semi-circular plate 8. The semi-circular plates 8 in the two positioning cards 4 are spliced ​​together to form a cylindrical sleeve, and the inner diameter of the cylindrical sleeve is the same as the outer diameter of the installed water pipe 1. The semi-circular plates 8 in the two guide cards 6 are spliced ​​together to form a cylindrical sleeve, and the inner diameter of the cylindrical sleeve is the same as the outer diameter of the water pipe 2 to be installed.

[0022] like Figure 1 As shown, in this embodiment, the connecting plates on the same side of the two positioning cards 4 are fastened together by positioning bolts 5, and the connecting plates on the same side of the two guide cards 6 are fastened together by guide bolts 7. The connecting plate of the positioning card 4 has a through hole for the positioning bolts 5 to pass through, and the connecting plate of the guide card 6 has a through hole for the guide bolts 7 to pass through.

[0024] In actual use, the rubber pads can act as a buffer to prevent damage to the water pipes during movement.

[0025] In this embodiment, one of the semi-circular plates 8 in the positioning card 4 is integrally manufactured with the two connecting plates, and one of the semi-circular plates 8 in the guide card 6 is integrally manufactured with the two connecting plates; one end of the arc-shaped connecting rod 3 is fixed on one of the semi-circular plates 8 of the positioning card 4, and the other end of the arc-shaped connecting rod 3 is fixed on the corresponding semi-circular plate 8 of the guide card 6.

[0026] When using this utility model, preparation work is first required for transporting the water pipe to the installation area: A forklift is used to mount the DN300 water pipe onto a water pipe rack on a pallet of a diesel locomotive. After securing it with safety buckles, the locomotive transports it to the designated installation area. Then, the safety buckles are released, and one end of the unloaded water pipe crossarm is installed onto the water pipe hanger, and the other end onto the water pipe bracket. One water pipe crossarm is installed at each of the front and rear ends of the pallet truck. The angle of the water pipe crossarm should not be too large, just enough to allow the water pipe to move, to prevent injury during the rolling process. After preparation, install the positioning component at the tail of the installed water pipe 1. Move the water pipe 2 to be installed to the installation position, open the guide clip 6, and let the end of the water pipe 2 be installed into the guide clip 6. At this time, the tail of the water pipe 2 is placed on the water pipe hook of the water pipe bracket, and the end of the water pipe 2 is inside the guide clip 6. Use a pry bar to drag the water pipe 2 near the end of the water pipe 2 to be installed into the guide clip 6. After the water pipe 2 is connected with the installed water pipe 1, install the water pipe clamp to complete the water pipe extension. Finally, open the positioning bolt 5 and the guide bolt 7 and disassemble this water pipe assembly tool.

[0027] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
