Abstract
Description
Technical Field
[0001] The present application relates to the field of underground integrated pipe corridors, and in particular to an anti-floating device for underground pipe corridors. Background Art
[0002] At present, most underground pipe corridors are rectangular structures. However, because the pipe corridors have uniform specifications and are buried deep, and the entire pipe corridor project is usually a dangerous and large project exceeding a certain scale, the foundation pit construction period is long. In order to speed up the progress of on-site construction, factory production, on-site tensioning and splicing, and segmented construction are often used. Therefore, when the pipe corridor is affected by the water buoyancy generated by groundwater, the pipe corridor is more likely to lose balance and tilt, resulting in cracks and water leakage at the connection of the pipe corridor, affecting normal use.

[0025] The following further elaborates on the present application in conjunction with the attached Figures 1-3 for further detailed description.
[0026] The embodiment of the present application discloses an anti-floating device for an underground utility tunnel. Refer to Figure 1 、 Figure 2 、 Figure 3The underground pipe gallery anti-floating device includes multiple anti-floating parts and a concrete layer 6. The multiple anti-floating parts are arranged on both sides of the bottom of multiple pipe gallery bodies 1. The multiple pipe gallery bodies 1 are arranged in sequence along the axial direction. The anti-floating parts can widen the bottom of the pipe gallery body 1; the concrete layer 6 is cast on both sides of the bottom of the pipe gallery body 1 and covered with the anti-floating parts. The concrete layer 6 is connected to the pipe gallery body 1 through the anti-floating parts, which is used to increase the weight of the bottom of the pipe gallery body 1, to prevent the pipe gallery from floating, and to effectively prevent the anti-floating parts from corroding.
[0027] Reference Figure 1 , Figure 2 , Figure 3 Anchor claws 3 are pre-buried at the bottom of the tunnel body 1, and the anchor claws 3 are fixedly connected to the outer side of the tunnel body 1 with welding parts 3, which can be steel plates.
[0028] Reference Figure 1 , Figure 2 , Figure 3 The anti-floating parts include an anti-floating plate 4 and an anti-floating reinforcement 5. The anti-floating plates 4 are arranged on both sides of the bottom of the pipe gallery body 1. The anti-floating reinforcement 5 is welded to the bottom surface of the anti-floating plate 4, and the anti-floating plate 4 is welded to the upper part of the weldment.
[0029] Reference Figure 1 , Figure 2 , Figure 3 In this embodiment, three welding parts 3 are arranged on both sides of the bottom of each tunnel body 1, and three anti-floating reinforcements 5 are arranged on both sides of the bottom of each tunnel body 1. The anti-floating reinforcements 5 are welded to the welding parts 3 and correspond one to one.
[0030] Reference Figure 1 , Figure 2 , Figure 3 The anti-floating plate 4 is provided with pouring holes 7 for pouring concrete, making it easier to vibrate and compact the concrete.
[0031] Reference Figure 1 , Figure 2 , Figure 3 The diameter of the casting hole 7 on the anti-floating plate 4 is 100-150 mm.
[0032] Reference Figure 1 , Figure 2 , Figure 3 The thickness of the anti-floating plate 4, the welded part 3, and the anti-floating part reinforcement 5 is greater than 10 mm.
[0033] Reference Figure 1 , Figure 2 , Figure 3 The connection method between the weldment 3 and the anti-floating part is welding. The welds between the anti-floating plate 4, the anti-floating part reinforcement 5 and the weldment 3 must be fully welded, and the welding angle is not less than 6mm.
[0034] Refer to Figure 1 、 Figure 2 、 Figure 3 , a gap of 100 - 150 mm is reserved between every two anti - floating plates 4 on each side of the bottom of the multiple pipe gallery bodies 1 for pouring concrete.
[0035] When installing the underground pipe gallery anti - floating device in this embodiment, during the production process of the pipe gallery body 1, 6 welded parts 3 are welded to the anchoring claws 3 of the pipe gallery body 1 for fixation, with 3 pieces on each side of the pipe gallery body 1. Then, after the pipe gallery body 1 is poured, it is placed on the jig so that the welded part 3 has a certain height from the ground, facilitating the welding construction of the anti - floating parts. Next, 6 anti - floating part stiffeners 5 are vertically welded to the welded part 3 according to the drawing dimensions for fixation. The anti - floating plate 4 is cut out with grouting holes by numerical control cutting. The fabricated anti - floating plate 4 is placed on the anti - floating part stiffener 5 to align the anti - floating plate 4 with the pipe gallery body 1, and the anti - floating plate 4 is welded and fixed to the anti - floating part stiffener 5 and the welded part 3. The fabricated pipe gallery is transported to the site for assembly construction. After the on - site installation construction of the entire section of the pipe gallery is completed, the anti - floating parts and the welded part 3 are wrapped with a concrete layer 6. During the pouring process of the concrete layer 6, it needs to be vibrated densely. The concrete wrapping plays an effective anti - corrosion role for the steel plate. The concrete layer 6 is connected to the pipe gallery body 1 through the anti - floating parts, which is used to increase the weight of the bottom of the pipe gallery body 1. The concrete layer 6 widens the bottom of the pipe gallery body 1. After backfilling the soil above the concrete layer, the backfilled soil presses on the concrete layer. The weight of the backfilled soil above the concrete layer combined with the self - weight of the pipe gallery body 1 helps to prevent the pipe gallery body 1 from floating.
[0036] In this application, by setting welded parts on the pipe gallery body, the situation where non - general - specification precast pipe galleries need to re - process molds is avoided, reducing the cost and cycle of mold modification. In this application, during the waiting period when the concrete strength of the pipe gallery body reaches the design value, the anti - floating part stiffening plate and the anti - floating plate are welded on the embedded parts, shortening the on - site assembly cycle.
[0037] The above are all the preferred embodiments of this application. The protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
