Description

Technical Field

[0001] The present invention relates to the technical field of pipe corridors, and in particular to an integrated pipe corridor. Background Art

[0002] By setting the pipe gallery in the stratum, the pipe gallery can be used as an underground passage for municipal pipelines such as drainage, rainwater and sewage, heating, electricity, communications, and gas, so that various municipal engineering pipelines can be arranged more centrally, which is convenient for the installation and maintenance of various pipelines and ensures the stable operation of urban functions. Since the pipe gallery is generally long and needs to be set in different types of strata, different strata will have different effects on the pipe gallery. In particular, when the pipe gallery is set in a liquefiable soil layer, the liquefiable soil layer is prone to liquefaction under the action of an earthquake, and the pipe gallery is prone to floating or sinking to varying degrees in the liquefied soil layer, thereby changing the position of the pipe gallery in the soil layer and even destroying the structural integrity of the pipe gallery, thereby affecting the safety of the municipal pipelines in the pipe gallery.

[0003] Therefore, how to improve the stability of the pipe gallery in the liquefiable soil layer has become an urgent problem to be solved.

[0043] 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.

[0044] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides an integrated pipeline corridor for being arranged in a soil layer 100, the integrated pipeline corridor at least comprising a pipeline corridor base 1, a first enclosure structure 2, a second enclosure structure 3 and a supporting structure 4, the pipeline corridor base 1 having a pipeline channel; the first enclosure structure 2 is arranged along the extension direction of the pipeline corridor base 1 and is arranged on both sides of the pipeline corridor base 1; the second enclosure structure 3 is arranged along the extension direction of the pipeline corridor base 1 and is arranged on the periphery of the first enclosure structure 2; the supporting structure 4 is arranged along the extension direction of the pipeline corridor base 1 and is connected to the first enclosure structure 2 on both sides, and the supporting structure 4 and the first enclosure structure 2 form a protective space for accommodating the pipeline corridor base 1.

[0045] On the whole, when the integrated pipe gallery is in use, the pipe gallery base 1 is set in the soil layer 100, and various pipelines can be arranged through the pipeline channels in the pipe gallery base 1, thereby improving the convenience of pipeline arrangement.

[0046] The soil layer 100 may be any type of soil layer 100 and is not specifically limited herein. Preferably, the soil layer 100 is a liquefiable soil layer 100, such as liquefiable sandy soil such as silt or silt sand. Figure 1 As shown, since the pipeline gallery matrix 1 is a hollow structure, when the pipeline gallery matrix 1 is embedded in the soil layer 100, the presence of the pipeline gallery matrix 1 will make the stress of the soil layer 100 near the pipeline gallery matrix 1 smaller than the stress of the original soil layer 100.

[0047] In particular, when the tunnel matrix 1 is set in the area of ​​the deep liquefiable soil layer 100, when the deep liquefiable soil layer 100 liquefies, the lateral expansion of the liquefiable soil layer 100 will flow to the lower part of the tunnel matrix 1, and in the soil layer 100 at a certain depth, the change in the lateral expansion of the surface of the liquefied soil layer 100 will be weakened.

[0048] In order to reduce the impact of the liquefiable soil layer 100 on the pipeline gallery matrix 1, a first retaining structure 2 is arranged on both sides of the pipeline gallery matrix 1, and the first retaining structure 2 can be embedded in the soil layer 100 to a certain depth, thereby isolating the lateral expansion impact of the liquefiable soil layer 100 outside the first retaining structure 2, reducing the impact of the liquefiable soil layer 100 on the pipeline gallery matrix 1, and allowing the pipeline gallery matrix 1 to be more stably maintained in the soil layer 100.

[0049] A second retaining structure 3 is further provided on the periphery of the first retaining structure 2 , and the second retaining structure 3 can further play a protective role, reducing the impact of the lateral flow of the liquefiable soil layer 100 on the first retaining structure 2 , thereby improving the stability of the tunnel base 1 .

[0050] In addition, a supporting structure 4 is provided between the first enclosure structures 2. The supporting structure 4 forms a protective space by connecting with the first enclosure structures 2 on both sides, and the pipe gallery base 1 is provided in the protective space. The supporting structure 4 can better support the pipe gallery base 1, and the supporting structure 4 can cooperate with the first enclosure structure 2 to better isolate the expansion influence of the liquefiable soil layer 100, further ensuring the stability of the pipe gallery base 1.

[0051] The present invention significantly improves the anti-floating and anti-sedimentation capabilities of the pipeline gallery base 1 by arranging a first enclosure structure 2, a second enclosure structure 3 and a supporting structure 4 on the periphery of the pipeline gallery base 1, so that the pipeline gallery base 1 can be more stably maintained in the soil layer 100, thereby enabling better layout of various pipelines.

[0052] Especially in the area of ​​deep liquefiable soil layer 100, even when the deep liquefiable soil layer 100 is affected by vibration, the first retaining structure 2, the second retaining structure 3 and the supporting structure 4 can cooperate to provide good protection for the corridor base 1, which can prevent the underground integrated corridor from floating when the deep liquefiable area liquefies on a large scale, and prevent the uneven settlement of the corridor base 1 caused by the dissipation of pore pressure in the soil layer 100 after the earthquake.

[0053] When the liquefiable soil layer 100 encounters vibration, the gas in the liquefiable soil layer 100 will float and dissipate, thereby causing the liquefiable soil layer 100 to settle. At this time, the supporting structure 4 can still provide good support for the pipeline gallery base 1, thereby preventing the pore pressure in the liquefiable soil layer 100 from dissipating after the earthquake and causing uneven settlement of the pipeline gallery base 1, thereby improving the stability of the pipeline gallery base 1 in the soil layer 100.

[0054] In an embodiment of the present invention, Figure 2 In the illustrated embodiment, the first enclosure structure 2 includes two first enclosure bases 21 , which are both arranged along the extension direction of the pipe gallery base 1 and are respectively placed on both sides of the pipe gallery base 1 .

[0055] By arranging the first enclosure matrix 21 on both sides of the tunnel matrix 1, the first enclosure matrix 21 can isolate the lateral expansion impact of the liquefied soil layer 100 on the outside of the tunnel matrix 1, thereby preventing the liquefiable soil layer 100 from affecting the stability of the tunnel matrix 1.

[0056] Specifically, the first enclosure matrix 21 is a combination of one or more of reinforced concrete sheet piles, underground continuous walls, reinforced concrete interlocking piles, or continuous wall structures with considerable bending stiffness.

[0057] Of course, designers can adjust the specific structure of the first enclosure base 21 according to usage requirements, and no specific restrictions are made here.

[0058] The designer can calculate the depth of the first retaining matrix 21 embedded in the soil layer 100 according to the specific conditions on site, and no specific numerical value is imposed here.

[0059] Furthermore, in order to facilitate the construction, the horizontal distance between the first enclosure base 21 and the pipe gallery base 1 is not less than 800 mm.

[0060] In an embodiment of the present invention, the supporting structure 4 includes a supporting layer 41 , which is laid between two first enclosure substrates 21 along the extension direction of the tunnel substrate 1 , and the tunnel substrate 1 is placed on the supporting layer 41 .

[0061] By laying the supporting layer 41 between the two first retaining substrates 21, a protective space can be formed between the supporting layer 41 and the first retaining substrates 21 on both sides. By burying the pipeline gallery substrate 1 in the soil layer 100 in the protective space, the liquefiable soil layer 100 is isolated, which significantly reduces the impact of the liquefiable soil layer 100 on the pipeline gallery substrate 1, so that the pipeline gallery substrate 1 can be more stably maintained at the set depth of the soil layer 100.

[0062] In a specific embodiment, the supporting layer 41 is a non-liquefied cemented soil layer. The non-liquefied cemented soil layer and the tunnel base 1 can also cooperate to form an effective weight, thereby resisting the buoyancy stress of the liquefiable soil layer 100 below the non-liquefied cemented soil layer, and preventing the tunnel base 1 from floating up significantly. Preferably, the supporting layer 41 is constructed by physical grouting, chemical grouting or microbial grouting.

[0063] Of course, designers can use other methods to construct the supporting layer 41 according to the on-site conditions, and no specific restrictions are made here.

[0064] In an embodiment of the present invention, the integrated pipe gallery further comprises a support structure 5 arranged at the bottom of the pipe gallery base 1 , and the pipe gallery base 1 is arranged on a supporting layer 41 through the support structure 5 .

[0065] By arranging a support structure 5 at the bottom of the tunnel base 1, the support structure 5 can support the first enclosure base 21 on both sides in the horizontal direction, thereby improving the horizontal stability of the first enclosure base 21 and preventing the first enclosure base 21 from tilting.

[0066] In a specific embodiment, if Figure 3In the illustrated embodiment, the support structure 5 includes a plurality of cross beams 51 , which are arranged at intervals along the extension direction of the tunnel base 1 and connected to the bottom of the tunnel base 1 , and the two ends of the cross beams 51 abut against the first enclosure base 21 on both sides.

[0067] Preferably, the cross beam 51 is a steel beam or a concrete beam. Moreover, the cross section of the cross beam 51 can be set to be rectangular, T-shaped, box-shaped, etc., which is not specifically limited here. Among them, the cross beam 51 can be constructed by prefabrication or on-site casting.

[0068] By making the two ends of the cross beam 51 abut against the first enclosure bases 21 on both sides, the cross beam 51 can support the first enclosure bases 21 on both sides in the horizontal direction, thereby improving the lateral bending rigidity of the first enclosure bases 21 on both sides.

[0069] Especially in the liquefiable soil layer, when the liquefiable soil layer flows laterally, the liquefiable soil layer will drive the bottom of the first retaining matrix 21 on both sides to tilt inward, and through the cooperation of multiple cross beams 51, the first retaining matrix 21 on both sides can be laterally supported, thereby preventing the first retaining matrix 21 from tilting and improving the structural stability of the first retaining matrix 21.

[0070] Furthermore, since the cross beam 51 is not connected to the first retaining matrix 21 , the vertical settlement of the first retaining matrix 21 will not be directly transmitted to the cross beam 51 , thereby not affecting the stability of the cross beam 51 and the tunnel matrix 1 in the soil layer 100 .

[0071] Of course, designers can adjust the number and spacing of the beams 51 according to usage requirements, and no specific restrictions are made here.

[0072] During the construction process, the original soil layer in the protection space is generally removed first, and then the pipe gallery base 1 is lowered into the protection space. At this time, there is a construction gap in the protection space. In an embodiment of the present invention, the integrated pipe gallery further includes a backfill layer 6, which is filled and arranged in the protection space.

[0073] By filling the backfill layer 6 in the protection space, the backfill layer 6 can be used to eliminate the construction gap and prevent the pipeline gallery base 1 from moving in the protection space.

[0074] The designer can adjust the specific material of the backfill layer 6 according to the use requirements, and no specific limitation is made here. Preferably, the backfill layer 6 is made of backfill soil, and the compactness and relative density of the backfill soil should be controlled so that the backfill soil does not liquefy.

[0075] In a specific embodiment, at least part of the backfill layer 6 is placed above the tunnel base 1. By placing part of the backfill layer 6 above the tunnel base 1, the backfill layer 6 can cooperate with the non-liquefied cemented soil layer and the tunnel base 1 to further increase the effective weight, which is beneficial to resist the buoyant stress of the liquefiable soil layer 100.

[0076] Of course, in other embodiments, the top of the pipeline gallery base 1 can be directly placed on the ground of the soil layer 100, and no specific limitation is made here.

[0077] When the water in the liquefiable soil layer 100 enters the backfill layer 6 through the pores of the supporting layer 41, if the water is not discharged in time, the water will easily cause excess pore pressure accumulation in the backfill layer 6, and the backfill layer 6 will be easily destroyed under the impact of water flow, thereby affecting the stability of the area where the corridor base 1 is located.

[0078] In order to solve the above problems, in an embodiment of the present invention, the integrated pipe gallery further includes a drainage structure 7 , which is arranged along the extension direction of the pipe gallery base 1 and is placed on the periphery of the pipe gallery base 1 .

[0079] By setting a drainage structure 7 on the periphery of the tunnel matrix 1, when water enters the backfill layer 6 through the pores of the supporting layer 41, the water will flow into the drainage structure 7 and be discharged, thereby avoiding the problem of excess pore pressure accumulation of water near the tunnel matrix 1 and ensuring the stability of the tunnel matrix 1.

[0080] In a specific embodiment, the drainage structure 7 includes two vertical drainage layers 71 arranged on both sides of the tunnel base 1, and a transverse drainage layer 72 arranged at the bottom of the tunnel base 1. The vertical drainage layer 71 extends downward from the ground of the soil layer 100 and is connected to the transverse drainage layer 72.

[0081] Preferably, the vertical drainage layer 71 and the horizontal drainage layer 72 are both gravel layers. The gravel layer has abundant pores and can play a good role in drainage. In addition, the gravel layer also has good supporting performance and will not affect the stability of the backfill layer 6.

[0082] Of course, in other feasible embodiments, designers can adjust the specific structures of the vertical drainage layer 71 and the horizontal drainage layer 72 according to usage requirements, and no specific restrictions are made here.

[0083] In an embodiment of the present invention, the second enclosure structure 3 includes a plurality of second enclosure bases 31, and the plurality of second enclosure bases 31 are arranged along the extension direction of the tunnel gallery base 1, at least part of the second enclosure bases 31 are arranged at intervals on the periphery of one of the first enclosure bases 21, and the remaining part of the second enclosure bases 31 are arranged at intervals on the periphery of another first enclosure base 21.

[0084] By arranging a plurality of second retaining bases 31 on the periphery of the first retaining structure 2, the plurality of second retaining bases 31 can further block the expansion influence of the liquefiable soil layer 100, so that the area where the first retaining structure 2 and the pipeline gallery base 1 are located has better stability, avoiding the problem of obvious floating or sinking of the pipeline gallery base 1 in the soil layer 100.

[0085] Specifically, the second retaining matrix 31 includes retaining piles 311, which are extended downward from the ground of the soil layer 100. Preferably, the retaining piles 311 are graded gravel piles. The retaining piles 311 are vertically arranged and embedded in the soil layer 100, and the bottom of the retaining piles 311 can be placed below the first retaining matrix 21.

[0086] Furthermore, the depth of the graded gravel piles should reach the deep liquefiable soil layer 100, so that when liquefaction occurs, the graded gravel piles can quickly dissipate the pore water pressure to reduce the lateral expansion of the liquefied soil layer 100. The designer can adjust the depth of the retaining piles 311 embedded in the soil layer 100 according to the use requirements, and no specific numerical limit is imposed here.

[0087] Furthermore, the plurality of second enclosure base bodies 31 are symmetrically arranged with respect to the pipe gallery base body 1. Preferably, the plurality of second enclosure base bodies 31 are arranged at equal intervals, thereby improving the uniformity of protection between the plurality of second enclosure base bodies 31.

[0088] Designers can adaptively adjust the size, number and arrangement interval of the retaining piles 311 according to the on-site geological conditions and the degree of liquefaction in the deep liquefied zone, and no specific restrictions are made here.

[0089] In other feasible embodiments, the retaining piles 311 are a combination of one or more gravel drainage piles, rigid drainage piles, or other structures having a certain strength and capable of rapid drainage, and no specific limitation is made herein.

[0090] Of course, designers can set the second enclosure base 31 to other structures according to usage requirements, and no specific restrictions are made here.

[0091] Designers can adjust the cross-sectional shape of the pipe gallery base 1 according to the use requirements, such as rectangular, circular or elliptical, etc., and there is no specific limitation here. Preferably, the cross-sectional shape of the pipe gallery base 1 is set to be rectangular, and the pipe gallery base 1 includes a top plate, a bottom plate and two side plates, and the top plate, the bottom plate and the two side plates are surrounded to form the pipe gallery base 1.

[0092] In an embodiment of the present invention, the integrated pipe gallery further comprises a partition structure 8 arranged in the pipe gallery matrix 1, and the partition structure 8 divides the pipeline channel into at least two relatively independent pipeline accommodating chambers.

[0093] By arranging the partition structure 8 in the pipe gallery base 1, the pipeline channel can be divided into a plurality of relatively independent pipeline accommodating chambers by using the partition structure 8. Different pipelines can be arranged through different pipeline accommodating chambers, which has a better use effect.

[0094] Specifically, the partition structure 8 includes at least one partition plate, which is vertically arranged to divide the pipeline channel into at least two relatively independent pipeline accommodating chambers.

[0095] In other embodiments, designers can adjust the specific structure of the partition structure 8 according to usage requirements, and no specific limitation is made here.
