Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated assembled pipe corridors, and in particular to a prefabricated concrete pipe corridor structure and a construction method of the prefabricated concrete pipe corridor. Background Art

[0002] The application of integrated pipe corridors in municipal pipelines effectively alleviates the contradiction between land resource shortage and urban functional requirements, and improves the utilization rate of underground space. It avoids the problem of repeated excavation and construction of the road surface in busy areas, and effectively solves the problems of "street zippers" and "spider webs in the sky". Prefabricated prefabricated pipe corridors are widely used because of their great advantages in quality and construction period, which is conducive to the green construction of urban infrastructure. Prefabricated pipe corridors are cast in sections in the factory, and the assembly process is used on site to form an integrated pipe corridor.

[0003] Prefabricated pipe corridors also face many technical problems: pipe segments are prefabricated in the factory, while the concrete cushion is cast on site. The prefabricated pipe segments are placed directly on the cushion in a "hard-on-hard" manner. It is impossible for the two to fit completely, and stress concentration will inevitably occur in local positions of the bottom plate. As time goes by, fatigue cracks will occur in the pipe corridor, affecting the overall safety and stability of the pipe corridor. Furthermore, the prefabricated pipe segments are placed on the cushion, and the sealant on the outside of the bottom plate at the splicing position of the pipe segments is difficult to apply. These will affect the normal operation and use of the pipe corridor in the later stage and reduce the durability of the pipe corridor. In addition, the construction and equipment of the prefabricated pipe corridor are more complicated, requiring a larger working surface. Summary of the invention

[0004] The purpose of the present invention is to provide a prefabricated concrete pipe gallery structure and a construction method of a prefabricated concrete pipe gallery, so as to solve the technical problem that the prefabricated concrete pipe gallery is difficult to assemble and it is difficult to ensure the overall sealing of the pipe gallery.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Solution 1

[0042] The present invention provides a prefabricated concrete pipe gallery structure, such as Figure 1-Figure 5 As shown, it includes: a cushion block 3, a track group 1, a grouting part 4, a sealant 7 and a plurality of prefabricated pipe segments 6, and the plurality of prefabricated pipe segments 6 are distributed in the longitudinal direction; a track group 1 is fixed on the cushion block 3, and the prefabricated pipe segments 6 are arranged on the track group 1, and the track group 1 is located at the intersection of two adjacent prefabricated pipe segments 6; the track group 1 includes a first track 11 and a second track 12 distributed in the longitudinal direction at intervals, the first track 11 corresponds to one of the two adjacent prefabricated pipe segments 6, and the second track 12 corresponds to the other of the two adjacent prefabricated pipe segments 6; and a track group spacing 13 is arranged between the first track 11 and the second track 12; a grouting part 4 is arranged between the cushion block 3 and the prefabricated pipe segment 6; and the sealant 7 is arranged between two adjacent prefabricated pipe segments 6.

[0043] During the construction of the concrete prefabricated pipe gallery structure provided by the present invention, after the prefabricated pipe segment 6 is placed on the track group 1 by a crane, it can be moved along the track group 1 to adjust its position, thereby releasing the crane, solving the problem of completely relying on the crane when adjusting the position of the pipe segment, and is conducive to improving work efficiency.

[0044] When the prefabricated pipe segment 6 moves along the first track 11 and the second track 12 in the track group 1, the friction force on the bottom of the prefabricated pipe segment 6 is small, which is beneficial to prevent damage to the preset waterproof layer at the bottom of the prefabricated pipe segment 6, ensure the waterproof performance of the later pipeline corridor, and protect the integrity of the pipe segment structural layer.

[0045] A track group spacing 13 is set between the first track 11 and the second track 12, which makes it possible to set the sealant 7 between two adjacent prefabricated pipe sections 6, solves the construction problem of the sealant 7 on the outer side of the bottom plate at the joint of the prefabricated pipe sections 6, thereby ensuring the sealing of the pipe section joints and the integrity of the pipe gallery.

[0046] By grouting, a grouting part 4 is set between the cushion block 3 and the prefabricated pipe segment 6, and the space between the prefabricated pipe segment 6 and the cushion block 3 is filled with grouting to ensure that the prefabricated pipe segment 6 is evenly stressed and prevent stress concentration at the bottom, thereby solving the stress concentration problem between the pipe segment and the concrete cushion layer in the traditional process and ensuring the overall safety and stability of the concrete prefabricated pipe gallery structure. Preferably, grouting is performed between the foundation soil and the bottom of the prefabricated pipe segment 6, so that the grouting part 4 is not only formed between the cushion block 3 and the prefabricated pipe segment 6, but can also fill the space between the foundation and the prefabricated pipe segment 6 with grouting.

[0047] The prefabricated pipe segment 6 may be a prefabricated standard segment pipe segment. Figure 4 and Figure 5 As shown, a pipe segment spacing 61 is provided between two adjacent prefabricated pipe segments 6, and the lower opening of the pipe segment spacing 61 is located above the middle of the track group spacing 13; the sealant 7 is provided in the pipe segment spacing 61. The area of ​​the pipe segment spacing 61 close to the cushion block 3 is blocked by the cushion block 3, so it is difficult to apply the sealant 7. By providing the track group spacing 13, the sealant 7 can be applied to the area of ​​the pipe segment spacing 61 close to the cushion block 3 through the track group spacing 13, so that the sealant 7 can also be applied to the outer side of the bottom plate of the prefabricated pipe segment 6, thereby ensuring the integrity of the sealant 7 and improving the sealing of the joint of the prefabricated pipe segment 6.

[0048] Furthermore, the pipe segment spacing 61 is provided with a glue anti-leakage auxiliary strip 10, and the sealant 7 is formed on the glue anti-leakage auxiliary strip 10, so as to ensure the flatness and regularity of the sealant 7 on the outer side of the bottom plate of the prefabricated pipe segment 6, prevent the occurrence of poor bonding, ensure the sealing effect, and improve the overall sealing of the pipe gallery. Specifically, the glue anti-leakage auxiliary strip 10 can be firmly pasted at the bottom end of the splicing seam of the bottom plate of the prefabricated pipe segment 6.

[0049] In one embodiment, the outer shell of the prefabricated pipe segment 6 is provided with a plurality of vertically distributed sealing rings 9, and the sealing rings 9 are at least partially located in the pipe segment spacing 61. Figure 4 and Figure 5 As shown, the outer wall of the prefabricated pipe section 6 is provided with a groove, the sealing ring 9 is positioned in the groove, and the sealing ring 9 is at least partially located in the pipe section spacing 61 and abuts against the adjacent prefabricated pipe section 6, thereby improving the sealing of the joint. The sealing ring 9 is preferably a rubber composite sealing ring 9.

[0050] In one embodiment, the cushion block 3 is provided with an embedded part 2, and the first rail 11 and the second rail 12 are both welded to the embedded part 2. Figure 2 and Figure 3 As shown, the first rail 11 and the second rail 12 can be steel rails. A rail group spacing 13 is set between the first rail 11 and the second rail 12 in the same rail group 1, and a spacing is also set between the rail groups 1 distributed longitudinally, that is, the first rail 11 and the second rail 12 are distributed longitudinally, which is not full-length and segmental, which greatly saves costs while ensuring the smooth implementation of the project.

[0051] The pad 3 may be a concrete pad 3, which may be cast in situ on the foundation surface. Figure 1 and Figure 4 As shown, the concrete prefabricated pipe gallery structure includes a plurality of pads 3 distributed at intervals along the longitudinal direction, and the pads 3 correspond to the intersections of two adjacent prefabricated pipe sections 6.

[0052] In one embodiment. Figure 2 As shown, the cross section of the prefabricated pipe segment 6 is in the shape of a rectangular frame. However, the cross section of the prefabricated pipe segment 6 is not limited to a rectangular shape, and may also be in a circular, elliptical, polygonal or irregular shape.

[0053] like Figure 2 and Figure 4 As shown, the prefabricated pipe segment 6 is provided with a plurality of reserved holes, and the reserved holes are located at the corners of the prefabricated pipe segment 6; positioning columns are provided in the corresponding reserved holes of two adjacent prefabricated pipe segments 6. The positioning columns cooperate with the corresponding reserved holes of two adjacent prefabricated pipe segments 6 to accurately position the prefabricated pipe segments 6 and ensure that the gaps between the prefabricated pipe segments 6 are of the designed size.

[0054] Furthermore, the reserved hole is a bolt hole 5, the positioning column is a positioning fastening bolt 8, the size of the bolt hole 5 should be coordinated with the positioning fastening bolt 8, the positioning fastening bolt 8 is inserted into the bolt hole 5, and the positioning fastening bolt 8 is tightened to accurately position the prefabricated pipe section 6. During the process of tightening the positioning fastening bolt 8, the prefabricated pipe section 6 moves on the first track 11 and the second track 12, and the friction force when the bottom of the prefabricated pipe section 6 moves is small, which is convenient for adjusting the position of the prefabricated pipe section 6.

[0055] The concrete prefabricated pipe gallery structure provided by the present invention casts a cushion block 3 on the foundation at the joint of the prefabricated pipe section 6, and a track group 1 is arranged above the cushion block 3. The bottom surface of the prefabricated pipe section 6 directly contacts the first track 11 or the second track 12 in the track group 1. The first track 11 and the second track 12 provide support for the prefabricated pipe section 6, and make the prefabricated pipe section 6 easy to move longitudinally to adjust the position. The prefabricated pipe section 6 does not need to be provided with a pre-buried structure at the bottom in advance for movement to adjust the position. The spacing between the first track 11 or the second track 12 provides the possibility of implementing the sealant 7 on the outside of the bottom plate of the splicing seam of the bottom plate of the prefabricated pipe section 6, facilitates the construction of the sealant 7, solves the problem of the construction of the sealant 7 on the outside of the bottom plate at the joint of the prefabricated pipe section 6, ensures the sealing of the joint of the prefabricated pipe section 6, ensures the overall integrity of the pipe gallery, and provides an economical, convenient and safe implementation plan for the fixing and installation of the assembled prefabricated pipe gallery.

[0056] Solution 2

[0060] Furthermore, before hoisting the prefabricated pipe segment 6, grease is applied to the upper surface of the first rail 11 and the upper surface of the second rail 12. By setting the first rail 11 and the second rail 12 and polishing and lubricating the surfaces of the first rail 11 and the second rail 12, it is beneficial to reduce the friction when the bottom of the prefabricated pipe segment 6 moves, facilitate position adjustment, prevent damage to the preset waterproof layer at the bottom of the prefabricated pipe segment 6, ensure the waterproof performance of the later pipe gallery, protect the integrity of the pipe segment structure layer, save costs, and improve construction efficiency.

The adjacent prefabricated pipe segments 6 are tightened and installed with the positioning fastening bolts 8. After adjusting and installing in place, the outer side sealant 7 of the bottom plate joint of the prefabricated pipe segment 6 is constructed, and the bottom is fixed by grouting.

[0062] Specifically, the construction steps of the construction method of the prefabricated concrete pipe gallery provided by the present invention include:

The central position of the reserved space should be basically aligned with the joint seam of the bottom plate of the prefabricated pipe segment 6; the surface, side and end of the first track 11 and the second track 12 are polished and smooth, and the corners are rounded;

[0066] 4) Grease should be applied to the upper surface of the track before hoisting the prefabricated pipe segment 6;

[0067] 5) After the prefabricated pipe section 6 is hoisted onto the track group 1, a glue-applying anti-leakage auxiliary strip 10 is firmly pasted at the bottom end of the joint seam of the bottom plate of the prefabricated pipe section 6 to facilitate the later construction of the sealant 7; the glue-applying anti-leakage auxiliary strip 10 should be made of a flexible material, which can be selected according to the actual situation on site;
