[0002] During the construction of concrete structures, especially underground structures, various embedded parts are often present. The accuracy of the installation of these embedded parts directly determines whether the subsequent equipment installation work can proceed smoothly. During the construction of underground concrete structures, it is common to encounter situations where large waterproof sleeves need to be embedded. Conventional methods for installing large waterproof sleeves are not only time-consuming and labor-intensive, but also cannot guarantee the installation accuracy. For example, if the installation conflictes with the placement of the waterstop steel plate, the joint between the waterstop steel plate and the waterproof sleeve is prone to incomplete welding. Summary of the Invention

[0003] This application provides a large waterproof sleeve construction device, which solves the technical problems of traditional large waterproof sleeve installation methods being time-consuming and labor-intensive, unable to guarantee accuracy, and prone to missed welding at the joint.

[0004] To solve at least one of the above-mentioned technical problems, the technical solution adopted in this application is:

[0009] Furthermore, the axis of the waterproof sleeve is perpendicular to the length of the water-stop steel plate.

[0010] Furthermore, an arc-shaped groove for securing the outer wall of the waterproof sleeve is constructed on one end face along the length of the water-stop steel plate, and the outer wall of the waterproof sleeve is welded and fixed to the groove.

[0011] Furthermore, the water-stop steel plate is disposed below the waterproof sleeve or is disposed above the waterproof sleeve.

[0012] Furthermore, the support frame includes cross-arranged brackets and horizontal beams that connect the brackets laterally, forming a height-adjustable support mechanism.

[0013] Furthermore, the length direction of the crossbeam is arranged parallel to the axial direction of the waterproof sleeve.

[0015] Furthermore, each of the waterproof sleeves is equipped with two suspension hooks, which are symmetrically arranged relative to both ends of the waterproof sleeve.

[0016] Furthermore, the water-stop steel plate is constructed as a steel plate with a zigzag structure. Its cross-section includes a straight section in the middle and zigzag sections at both ends. The zigzag sections are symmetrically arranged with respect to the straight section and are inclined relative to the straight section with an obtuse angle. A semi-circular arc surface is provided at the center of the straight section, and the opening of the semi-circular arc surface is arranged facing the inclined side of the zigzag section.

[0023] In the picture: Detailed Implementation

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0025] This embodiment proposes a large-scale waterproof sleeve construction device, such as... Figure 1As shown, the system includes a waterproof sleeve 10 connected to the water-stop steel plate 20, and a support assembly for supporting suspension and adjusting the position of the waterproof sleeve 10. The support assembly includes a support leg 30 and a suspension hook 40 suspended from the support leg 30. The suspension hook 40 is adjusted vertically using a hand-cranked hoist 50. The support leg 30 is adjusted to the pre-embedded position and kept stable. Then, the waterproof sleeve 10 is suspended above the pre-embedded position using the suspension hook 40. Finally, the suspension hook 40 is controlled, and the hand-cranked hoist 50 is used to unload the waterproof sleeve 10 connected to the water-stop steel plate 20 to the pre-embedded position, preparing for pre-embedding.

[0026] like Figure 2-3 As shown, the axis of the waterproof sleeve 10 is perpendicularly intersected with the length of the waterstop steel plate 20; and an arc-shaped groove for securing the outer wall of the waterproof sleeve 10 is constructed on one end face of the waterstop steel plate 20 along its length, and the outer wall of the waterproof sleeve 10 is welded and fixed to the groove.

[0027] like Figure 2 As shown, the water-stop steel plate 20 is positioned below the waterproof sleeve 10; or, as Figure 3 As shown, the water-stop steel plate 20 is positioned above the waterproof sleeve 10. The choice between these two welded structures can be made based on actual working conditions and is frequently encountered in common pre-embedded treatments.

[0028] like Figure 4 As shown, the water-stop steel plate 20 is a steel plate with a special folded structure, and its cross-section is as follows: Figure 5 As shown, the structure includes a straight section 21 in the middle and bent sections 22 at both ends. The bent sections 22 are symmetrically arranged with respect to the straight section 21 and are inclined relative to the straight section 21 at an obtuse angle. Preferably, the angle between the straight section and the bent sections is 135° to prevent water flow. A semi-circular arc surface 23 is provided at the center of the straight section 21 to improve the strength of the straight section at this location and reduce stress concentration. Preferably, the opening of the semi-circular arc surface 23 faces the inclined side of the bent section 22, which facilitates both processing and placement.

[0029] Furthermore, the support frame 30 includes cross-arranged brackets 31 and a horizontal beam 32 that connects the brackets 31 horizontally, forming a height-adjustable support mechanism. When pre-embedding the waterproof sleeve 10, the support frame 30 needs to be assembled in advance at the pre-embedding location so that it can stably span the foundation pit at the pre-embedding location, so that the waterproof sleeve 10 with the water-stop steel plate 20 can be safely suspended.

[0030] The crossbeam 32 is arranged parallel to the axial direction of the waterproof sleeve 10 along its length, which facilitates the adjustment and installation of the pre-embedded waterproof sleeve 10, so that the waterproof sleeve 10 is aligned with the path of the foundation pit.

[0031] One end of the suspension hook 40 is connected to one end of the waterproof sleeve 10, and the other end is fastened to the crossbeam 32 by a hand-cranked hoist 50. Each waterproof sleeve 10 is equipped with two suspension hooks 40, which are symmetrically arranged with respect to the two ends of the waterproof sleeve 10.

[0032] A construction method for a large waterproof sleeve, using the construction device described above, includes the following steps:

[0033] S1. Based on the pre-embedded position, the waterproof sleeve 10 is welded to the water-stop steel plate 20 and moved to the pre-embedded position. The water-stop steel plate 20 is positioned below the waterproof sleeve 10; or, the water-stop steel plate 20 is positioned above the waterproof sleeve 10, which can be selected based on the actual working conditions.

[0034] S2. Based on the location of the pre-embedded position, assemble the support frame 30 and suspend the suspension hook 40 on the support frame 30. The cross-shaped brackets 31 and the horizontal beams 32 connecting the horizontal brackets 31 form a height-adjustable support mechanism. The support frame 30 is pre-assembled at the pre-embedded position to stably span the foundation pit at the pre-embedded position so that the waterproof sleeve 10 with the water-stop steel plate 20 can be safely suspended. At the same time, the length direction of the beam 32 is arranged parallel to the axis of the waterproof sleeve 10 to facilitate the adjustment and installation of the pre-embedded waterproof sleeve 10, so that the waterproof sleeve 10 is consistent with the path of the foundation pit.

[0035] S3. Control the suspension hook 40 to grab onto both ends of the waterproof sleeve 10. One end of the suspension hook 40 is connected to one end of the waterproof sleeve 10, and the other end is fastened to the crossbeam 32 by the hand-cranked hoist 50. The length of the suspension hook 40 is adjusted synchronously by the hand-cranked hoist 50 so that the waterproof sleeve 10 and the water-stop steel plate 20 are slowly lifted.

[0036] S4. Use a level placed on the inner wall of the horizontally positioned waterproof sleeve 10 to check if the levelness of the waterproof sleeve is up to standard. If the levelness on the level is up to standard, continue with the following steps; if it is not up to standard, continue to adjust the levelness of the waterproof sleeve 10 until it is up to standard.

[0037] S5. Then, use the hand crank 50 to adjust the length of the suspension hook 40 to adjust the position and height of the waterproof sleeve 10 to the preset position.

[0038] S6. After the position and height are adjusted, fix and reinforce the four sides of the waterproof sleeve 10 to ensure that the position of the waterproof sleeve 10 remains fixed.

[0039] S7. After reinforcement is completed, remove the suspension hook 40 and support bracket 30 in sequence.

[0040] S8. Repeat the above steps to install the other pre-embedded waterproof sleeves 10.

[0041] The large-scale waterproof sleeve construction device designed in this application has a simple structure, is easy and safe to move, and is convenient to manufacture. It allows for precise positioning of the waterproof sleeve before fixing, ensuring construction accuracy and effectively preventing incomplete welding at the junction of the water-stop steel plate and the waterproof sleeve. The device is easy to use and has a high reusability rate; it is safe to move and has high installation accuracy, and can be adapted to the installation of various large embedded parts; the construction operation is simple and efficient. This application also proposes a construction method for large-scale waterproof sleeves using this construction device.

These descriptions are merely preferred embodiments and should not be construed as limiting the scope of this application. All equivalent variations and modifications made within the scope of this application should still fall within the patent coverage of this application.
