Description

Technical Field

[0001] The present invention relates to the field of building technology, in particular to an earthquake-resistant underground pipe gallery prefabricated structure and a construction method thereof. Background Art

[0002] The core role of underground integrated pipeline corridors is to intensively manage urban pipelines, avoid repeated road excavation, and improve urban safety and operational efficiency. Specific functions can be summarized as follows: avoiding repeated road excavation and resource waste, extending pipeline life and reducing maintenance costs, intensively utilizing underground space and optimizing urban landscapes, improving urban safety and disaster prevention capabilities, and achieving economic and social benefits. In order to quickly lay underground comprehensive pipeline corridors, prefabrication is usually adopted, that is, the underground comprehensive pipeline corridor is split into assembly units one by one. When laying the underground comprehensive pipeline corridor, the complete underground comprehensive pipeline corridor can be laid by assembling the prefabricated assembly units. For the existing prefabricated underground comprehensive pipeline corridor assembly units, they are usually rectangular frames cast in cement. When laying the underground pipeline corridor, first, a foundation pit is excavated, and then the prefabricated assembly units are assembled one by one at the foundation pit through lifting equipment, and the pipes, lines, etc. are installed in the assembled underground pipeline corridor, and then waterproofing is done. Finally, backfill construction is carried out. Finally, the entire soil will cover the outside of the prefabricated rectangular assembly frame. When it is vibrated, the prefabricated underground pipeline corridor assembly unit cannot release the excess vibration force, resulting in excessive pressure on the outer wall of the assembly unit frame, and the pipes, lines, etc. arranged inside are also affected by the vibration. For this reason, we propose an earthquake-resistant underground pipeline corridor prefabricated structure and a construction method thereof. Summary of the Invention

[0007] Preferably, the casting partition is provided with a plurality of air holes, the air holes are evenly distributed on each casting section, and the air holes are expanded when opening toward the outer shape.

[0008] Preferably, the upper part of the cast partition is composed of two deformation zones, which are composed of deformation grooves. The deformation grooves are curved arc segments, and the radius of the deformation grooves gradually increases from the inner frame to the rectangular outer frame. The material hardness of the deformation zone is lower than the material hardness of the bottom of the cast partition.

[0009] Preferably, a positioning piece is provided at one end of the inner frame. The positioning piece is an outwardly protruding portion of the inner frame. The positioning piece is designed to be arched in imitation of the buffer interlayer, and the positioning piece fits with one end of the buffer interlayer.

[0010] Preferably, a plurality of pouring channels are distributed on the inner frame, and each pouring channel is connected by a pouring pipe, the pipe radius of the pouring channel is twice the pipe radius of the pouring channel, and the pouring pipes are distributed along the arch of the inner frame.

[0016] The present invention forms an elastic support between the inner frame and the rectangular outer frame by designing a cast partition, while also isolating and protecting the buffer component. The air holes on the cast partition are conducive to releasing the squeezed gas formed in the buffer layer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-8 The present invention provides a technical solution: a seismic-resistant underground pipe gallery prefabricated structure. This solution is used to solve the problem that the prefabrication of existing underground pipe galleries is not convenient for seismic resistance and is easy to cause damage to pipes and lines in the underground pipe gallery. The solution mainly includes a rectangular outer frame 1, which is made of cement as a whole. A plurality of corrugated grooves 11 are distributed on the outside of the rectangular outer frame 1, and a lifting groove 12 is provided on the rectangular outer frame 1. When casting the rectangular outer frame 1, two rectangular frame plates are used as casting templates, wherein the template serving as the outer frame is provided with grooves for casting to form the corrugated grooves 11. The corrugated grooves 11 are used to disperse the fill to the corrugated grooves 11 during subsequent backfilling, thereby reducing the concentration of the fill on the outside of the rectangular outer frame 1, which is beneficial to reducing the pressure of the fill on the rectangular outer frame 1. A lifting groove 12 is excavated on the outer wall of the rectangular outer frame 1. A hook is hung on the lifting groove 12 by a lifting device such as a crane, thereby lifting the prefabricated components of the underground pipe gallery into the excavated foundation pit.

[0028] As attached Figure 1-2As shown in the figure, an inner frame 2 is provided in the rectangular outer frame 1, a buffer layer 3 is reserved between the rectangular outer frame 1 and the inner frame 2, a buffer component 4 is provided in the buffer layer 3, the buffer component 4 includes a buffer interlayer 41, and a plurality of groups of buffer springs 42 are distributed between the buffer interlayer 41 and the inner wall of the rectangular outer frame 1, the buffer layer 3 covers the inner frame 2, the buffer interlayer 41 is arched, and the outer part of the inner frame 2 is designed to be an arch similar to the buffer interlayer 41, and the inner part of the inner frame 2 is a rectangular through groove, the rectangular through groove inside the inner frame 2 is embedded in the arch, and three groups of casting sections are assembled at the arch and the rectangular through groove of the inner frame 2. By designing the buffer interlayer 3 and the outer part of the inner frame 2 to be arched, the effect is achieved. The pressure is released. When the rectangular outer frame 1 is subjected to force, the corrugated groove 11 on the top of the rectangular outer frame 1 can first distribute and release part of the soil pressure, thereby avoiding the soil pressure from being too concentrated on the top of the rectangular outer frame 1. When the external covering soil is distributed on the top of the rectangular outer frame 1, the rectangular outer frame 1 is under pressure, and the pressure acts on the internal buffer spring 42, and then acts on the buffer interlayer 41 through the buffer spring 42, thereby releasing the pressure on the rectangular outer frame 1 and reducing the pressure on the inner frame 2. At the same time, since the buffer interlayer 41 and the inner frame 2 are both designed with arches, it is convenient to release the concentrated stress, which is better than the existing plate-shaped underground pipeline corridor to release the concentrated soil pressure.

[0029] In order to facilitate the laying of pipes and cables inside the inner frame 2, multiple groups of shock-absorbing brackets 43 are installed on the inner side walls of the inner frame 2. The design of the shock-absorbing brackets 43 is as shown in the attached figure. Figure 8 As shown in FIG, the bottom of the shock-absorbing bracket 43 is equipped with reinforcing ribs 44. The reinforcing ribs 44 and the shock-absorbing bracket 43 are mounted in a herringbone pattern on the inner wall of the inner frame 2. The top of the shock-absorbing bracket 43 is provided with multiple anti-slip textures 45. After the pipes and cables are arranged on the shock-absorbing bracket 43, they are tied along the anti-slip textures 45 with straps or other fixing methods to secure the pipes and cables to the shock-absorbing bracket 43.

[0030] The length of the rectangular outer frame 1 is greater than that of the inner frame 2 and the buffer layer 41. Casting partitions 5 are provided at both ends of the inner frame 2. The casting panels 5 are filled in the gaps between the inner frame 2 and the ends of the rectangular outer frame 1 by pouring cement.

[0031] The casting partition 5 is provided with a plurality of air holes 6 , which are evenly distributed on each casting section, and the air holes 6 have an expansion shape beyond the outer opening.

[0032] The upper part of the cast partition 5 is composed of two deformation zones, each of which is composed of a deformation groove 7. The deformation groove 7 is a curved arc segment, and the radius of the deformation groove 7 gradually increases from the inner frame 2 to the rectangular outer frame 1. The material hardness of the deformation zone is lower than the material hardness of the bottom of the cast partition 5.

[0033] A positioning piece 8 is provided at one end of the inner frame 2 . The positioning piece 8 is an outwardly protruding portion of the inner frame 2 . The positioning piece 8 is arched in shape to imitate the buffer layer 41 , and fits in place with one end of the buffer layer 41 .

[0034] A plurality of pouring channels 21 are distributed on the inner frame 2 , and each pouring channel 21 is connected by a pouring pipe 22 . The pipe radius of the pouring channel 21 is twice the pipe radius of the pouring channel 21 , and the pouring pipe 22 is distributed along the arch of the inner frame 2 .

[0035] The outside of the rectangular outer frame 1 is distributed with a plurality of corrugated grooves 11 , which are semicircular depressions, and the rectangular outer frame 1 is provided with lifting grooves 12 .

[0036] When used specifically: first, cast the rectangular outer frame 1, using two rectangular frame plates as casting templates, and cast the rectangular outer frame 1 shown in the figure. By inserting the buffer interlayer 41 into the interior of the rectangular outer frame 1, the bottom edge of the buffer interlayer 41 and the edge of the rectangular outer frame 1 fit together, and the buffer spring 42 just rests against the inner wall of the rectangular outer frame 1. At this time, cement pouring is used to cast the buffer spring 42 and the bottom of the buffer interlayer 41 into the rectangular outer frame 1. Finally, push the pre-cast inner frame 2 into the buffer interlayer 41 until the positioning piece 8 fits the outside of the buffer interlayer 41. At this time, pour along the pouring channel 21, and convey multiple pouring channels 21 at the same time through multiple pouring pipes 22, so that the inner frame 2 and the buffer interlayer 41 form a casting layer.

[0037] A construction method used for a seismic-resistant underground pipe gallery prefabricated structure. A: Splice a single underground pipe gallery prefabricated part, push the buffer layer 3 into the rectangular frame, and fix the buffer spring 42 to the inner wall of the rectangular frame by pouring; B: Casting of the inner frame 2: Push the inner frame 2 into the buffer layer 3 and cast along the pouring path 21 so that the inner frame 2 and the buffer layer 3 fit together. C: Encapsulate and install the brackets, encapsulate the two cast partitions 5 at both ends of the inner frame 2, and assemble the shock-absorbing bracket 43 inside the inner frame 2; D: Excavate the foundation pit and lift the prefabricated parts of the underground pipe gallery. Use an excavator to excavate the foundation pit, and use the lifting equipment to lift the assembled prefabricated parts of the underground pipe gallery into the excavated foundation pit; E: Laying pipes and wires on the shock-absorbing bracket 43; F: Waterproofing and backfilling the pit.

[0038] After the three components of the prefabricated parts are assembled into one assembly unit respectively, it is necessary to lay multiple assembled prefabricated parts. First, a foundation pit is dug out using an excavator or other equipment, and the hook of the crane is hung on the lifting groove 12 of the rectangular outer frame 1 to lift the assembled rectangular outer frame 1. The rectangular outer frame 1 is placed in the foundation pit, and then multiple rectangular outer frames 1 are placed in sequence. By bundling cables and the like on the shock-absorbing bracket 43, the laying of the entire underground pipeline corridor prefabrication is completed.
