Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drain pipe installation, in particular to an installation structure of an internal drainage pipe of a shield tunnel. Background Technique

[0002] A shield tunnel refers to a tunnel excavated by the shield method and using a shield machine. The shield method is a fully mechanized construction method in the subaqueous tunneling method. It is to push the shield machine underground, prevent the surrounding rock from collapsing into the tunnel by the shield shell and segment support, and at the same time use a cutting device to excavate the soil in front of the excavation face, transport the soil out of the tunnel by an earth-moving machine, and rely on a jack to press and push forward at the rear, and assemble precast concrete segments to form a tunnel structure.

[0003] During the construction of a tunnel using the shield method, a large number of drain pipes often need to be installed during the construction process. The main function of installing drain pipes inside the shield tunnel is to drain the accumulated water in the tunnel and prevent water damage accidents. The drainage system ensures the dryness inside the tunnel by setting up sump pits, drainage ditches, water pumps and other facilities, as well as using waterproof materials and technologies for waterproof treatment, so as to maintain the stability and safety of the tunnel structure.

[0004] At present, when installing most internal drain pipes of shield tunnels, it is necessary to support the pipes first and then fix them, and the pipe support cannot be loosened during the fixing process. Therefore, the construction requirements are relatively high and difficult to meet. For this reason, an installation structure of an internal drainage pipe of a shield tunnel is proposed. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is: aiming at the above problems, to provide an installation structure of an internal drainage pipe of a shield tunnel.

[0006] The technical scheme adopted by the utility model is: an installation structure of an internal drainage pipe of a shield tunnel, characterized in that it includes:

[0007] Two pairs of hanging support plates, installed on the inner wall of the tunnel, symmetrically arranged on both sides of the drainage pipe, and a pair of support round rods are arranged at intervals along the axial direction between a pair of the hanging support plates;

[0008] A pipe reinforcement binding band is arranged below the drainage pipe, and both ends of the pipe reinforcement binding band respectively wind around the support round rods on both sides, and the pipe reinforcement binding band is used to support and support the drainage pipe;

[0009] Two fixed adjustment components are installed on the inner wall of the tunnel and symmetrically arranged on the adjacent sides of the suspension support plate. The corresponding ends of the fixed adjustment components are detachably connected to the pipeline reinforcement straps, and the fixed adjustment components can adjust the tightness of the pipeline reinforcement straps to fix the drainage pipeline.

[0010] By the above technical means, both ends of the pipeline reinforcement strap are wound around the support round rod and then connected to two fixed adjustment components respectively. The pipeline reinforcement strap supports the drainage pipeline, the fixed adjustment components fix the ends of the pipeline reinforcement strap, and the fixed adjustment components can adjust the tightness of the pipeline reinforcement strap, so there is no need to support the drainage pipeline for a long time during the installation and fixation process of the drainage pipeline.

[0011] In some embodiments, the fixed adjustment component includes a fixed screw, a lifting adjustment connecting plate and a fastening nut. The top end of the fixed screw is fixedly connected to the inner wall of the tunnel. The lifting adjustment connecting plate is provided with an insertion hole for the fixed screw to pass through. Installation grooves are provided at both ends of the pipeline reinforcement strap. The lifting adjustment connecting plate is clamped in the installation groove. The fastening nut is threadedly connected to the bottom of the fixed screw and provides fixed support for the lifting adjustment connecting plate.

[0012] In some embodiments, a pair of guiding support plates corresponding to the suspension support plate are provided on both sides of the fixed screw. The top of the guiding support plate is fixedly connected to the inner wall of the tunnel. Guiding strips distributed along the axial direction of the guiding support plate are provided on the opposite side walls of the guiding support plate. Positioning card slots that are mutually clamped with the guiding strips are provided on both sides of the lifting adjustment connecting plate, so that the lifting adjustment connecting plate can drive the end of the pipeline reinforcement strap to move vertically.

[0013] In some embodiments, a metal docking ring is provided in the installation groove, and a U-shaped bending part is provided at the end of the lifting adjustment connecting plate. The lifting adjustment connecting plate is mutually clamped with the metal docking ring through the U-shaped bending part.

[0014] In some embodiments, both the top end and the bottom end of the guiding support plate are bent at ninety degrees, so that the overall structure of the guiding support plate is Z-shaped. The bent parts at the bottom ends of a pair of guiding support plates can cooperate to limit the lifting adjustment connecting plate.

[0015] In some embodiments, a fixing perforation is provided at the top of the guiding support plate, and the guiding support plate is fixed to the inner wall of the tunnel by inserting an expansion bolt through the fixing perforation.

[0016] In some embodiments, the end of the pipeline reinforcement strap passes through in an S-shaped bend from the outside and the middle of a pair of support round rods.

[0017] In some embodiments, a waterproof coating is wrapped around the outer side of the pipeline reinforcement strap.

[0018] The beneficial effects of the present utility model are as follows:

[0019] 1. By pre-burying and installing multiple pairs of suspension support plates and multiple fixed adjustment components on the inner wall of the tunnel, connecting both ends of the pipeline reinforcement strap to the fixed adjustment components, placing the drainage pipeline at the middle position of the pipeline reinforcement strap in multiple installation structures, and then controlling the fixed adjustment components to adjust the tightness of the pipeline reinforcement strap, the drainage pipeline can be fixed. This installation process does not require long-term support for the drainage pipeline, thereby reducing the construction requirements and working intensity, and can also shorten the installation process of the drainage pipeline, improving the installation efficiency.

[0020] 2. By using the pipeline reinforcement strap to bind and fix the drainage pipeline, the pipeline reinforcement strap is made of strip-shaped material and has certain elasticity and buffering force. When the liquid is transported inside the drainage pipeline and vibration occurs, the pipeline reinforcement strap directly absorbs and cancels the vibration, and the vibration will not be transmitted to the fixed adjustment components, reducing the risk of loosening at the connection due to vibration.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.

[0030] Combination Figures 1 to 4 As shown, this embodiment is an installation structure for drainage pipes inside a shield tunnel, comprising two pairs of suspension support plates 2, pipe reinforcement bands 5 and two fixed adjustment components. Two pairs of suspension support plates 2 and two fixed adjustment components are installed on the inner wall of the tunnel. The two pairs of suspension support plates 2 are symmetrically arranged on both sides of the drainage pipe 1. A pair of support round bars 6 are inserted between the pair of suspension support plates 2 along their own axial intervals. The fixed adjustment components are symmetrically arranged on the adjacent sides of the suspension support plates 2. The pipe reinforcement band 5 is arranged below the drainage pipe 1. The two ends of the pipe reinforcement band 5 are respectively wound around the support round bars 6 on both sides and are detachably connected to the corresponding fixed adjustment components. The middle position of the pipe reinforcement band 5 can support the drainage pipe 1. The fixed adjustment component can adjust the tightness of the pipe reinforcement band 5 to fix the drainage pipe 1.

[0031] Further, such as Figure 3 As shown, the end of the pipeline reinforcement band 5 is bent in an S-shape and passes through the outer side and the middle of a pair of supporting round rods 6. Specifically, the outer side of the pipeline reinforcement band 5 is also wrapped with a waterproof coating.

[0032] In some embodiments, such as Figure 2 , 3 As shown in FIG. 4 , the fixed adjustment assembly includes a fixed screw 4, a lifting and adjusting connecting plate 11 and a fastening nut 8. The top of the fixed screw 4 is pre-buried and fixed to the inner wall of the tunnel. The lifting and connecting adjusting plate is provided with an insertion hole 14. The diameter of the insertion hole 14 is larger than the outer diameter of the screw, so that the screw can pass through the insertion hole 14. Both ends of the pipeline reinforcement band 5 are provided with mounting grooves 9, and the lifting and adjusting connecting plate 11 is clamped in the mounting grooves 9. The outer wall of the fixed screw 4 is formed with an external thread that matches the fastening nut 8. The fastening nut 8 is threadedly connected to the bottom of the fixed screw 4 and provides fixed support for the lifting and adjusting connecting plate 11.

[0033] By rotating the fastening nut 8, the fastening nut 8 moves upward along the fixing screw 4 and pushes the lifting and adjusting connecting plate 11 to move synchronously, and the pipe reinforcement band 5 is tightened, so that the pipe reinforcement band 5 presses the drainage pipe 1 against the inner wall of the tunnel, thereby realizing the installation and fixation of the drainage pipe 1.

[0034] Furthermore, a pair of guiding support plates 3 are provided on both sides of the fixing screw rod 4. The guiding support plates 3 correspond to the hanging support plates 2. The top of the guiding support plate 3 is fixedly connected to the inner wall of the tunnel. Guiding strips 13 are provided on the side walls of the opposite sides of the pair of guiding support plates 3 and are distributed along their own axial directions. Positioning slots 12 that are engaged with the guiding strips 13 are provided on both sides of the lifting and adjusting connecting plate 11, so that the lifting and adjusting connecting plate 11 can drive the end of the pipeline reinforcement strap 5 to move vertically. Specifically, two mutually parallel guiding strips 13 are provided on the side wall, and two positioning slots 12 are correspondingly provided on one side of the lifting and adjusting connecting plate 11. Through the mutual cooperation of the guiding strips 13 and the positioning slots 12, the lifting and adjusting connecting plate 11 can only perform linear motion in the vertical direction and provide partial lateral pressure to a certain extent to prevent the lifting and adjusting connecting plate 11 from directly falling between the two guiding support plates 3.

[0035] Furthermore, a metal docking ring 7 is fixedly provided inside the installation groove 9. The end of the lifting and adjusting connecting plate 11 is provided with a U-shaped bending part. The lifting and adjusting connecting plate 11 is engaged with the metal docking ring 7 through the U-shaped bending part. By connecting the lifting and adjusting connecting plate 11 with its end bent into a hook shape to the end of the pipeline reinforcement strap 5, it is ensured that the lifting and adjusting connecting plate 11 pulls the end of the pipeline reinforcement strap 5 during movement, and the end of the pipeline reinforcement strap 5 and the lifting and adjusting connecting plate 11 cannot easily fall off during the pulling process.

[0036] Furthermore, both the top end and the bottom end of the guiding support plate 3 are bent at a right angle, so that the overall structure of the guiding support plate 3 is Z-shaped. The bent parts at the bottom ends of the pair of guiding support plates 3 can cooperate to limit the lifting and adjusting connecting plate 11, thereby preventing the lifting and adjusting connecting plate 11 from falling between the two guiding support plates 3 due to gravity or the pulling force of the pipeline reinforcement strap 5. Specifically, a fixing perforation 10 is provided at the top of the guiding support plate 3, and the guiding support plate 3 is fixed to the inner wall of the tunnel by inserting an expansion bolt through the fixing perforation 10.

[0037] The implementation principle of an installation structure for an internal drainage pipeline in a shield tunnel in an embodiment is as follows:

[0038] First, the guiding support plates 3 and the hanging support plates 2 are fixed on the inner wall of the tunnel. Subsequently, both ends of the pipeline reinforcement strap 5 are bent in an S shape and passed through between and outside two adjacent supporting round rods 6, and the metal docking ring 7 at the end of the pipeline reinforcement strap 5 is connected to the U-shaped bending part of the lifting and adjusting connecting plate 11.

[0039] At this time, the staff passes the drainage pipe 1 through the middle of the pipe reinforcement strap 5 and the inner wall of the tunnel. After the drainage pipe 1 is placed, the two ends of the pipe reinforcement strap 5 are supported by the two lifting and adjusting connecting plates 11, and the drainage pipe 1 is supported by the pipe reinforcement strap 5, so that the staff does not need to support the drainage pipe 1.

[0040] Next, the staff only needs to turn the fastening nut 8 installed at the bottom end of the fixing screw 4, so that the fastening nut 8 moves upward along the axis of the fixing screw 4 and pushes the lifting and adjusting connecting plate 11 upward. When the lifting and adjusting connecting plate 11 moves upward, it pulls the end of the pipe reinforcement strap 5, and uses the pipe reinforcement strap 5 to squeeze the drainage pipe 1 against the inner wall of the tunnel and make the drainage pipe 1 fit the inner wall of the tunnel, realizing the installation and fixation of the drainage pipe 1. During the process, there is no need to support the drainage pipe 1 for a long time, reducing the working intensity, shortening the installation process of the drainage pipe 1, and improving the installation efficiency.

[0041] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
