Description

Technical Field

[0002] The underground integrated pipeline corridor is used to accommodate various municipal engineering pipelines, facilitating the construction, maintenance and monitoring of engineering pipelines. Figure 1 As shown in the figure, the existing underground integrated pipe corridors are mostly designed with rectangular cross-sections. The pipe corridors with this cross-section structure have low rigidity. When subjected to large surrounding fill pressure, such as Figure 2 As shown, the side wall of the tunnel will produce a large unstable deformation, affecting the normal structure and function of the tunnel. If the thickness of the tunnel side wall is simply increased, the degree of stiffness improvement will still be limited even if the material usage is greatly increased. That is, the stiffness improvement is not enough and the economy is also poor. Summary of the Invention

[0006] Preferably, the upper pressure plate includes a top plate and two inclined plates, the two inclined plates are respectively connected to the top plate and the upper mounting surface, there are two upper support plates, and the tops of the two upper support plates are respectively connected to the connection between the inclined plate and the top plate.

[0007] Preferably, the left pressure plate includes an upper left plate and a lower left plate connected to each other, the upper left plate extends downwardly at an angle to the lower middle part of the left mounting surface, and the top of the left support plate is connected to the upper left plate; the right pressure plate includes an upper right plate and a lower right plate connected to each other, the upper right plate extends downwardly at an angle to the lower middle part of the right mounting surface, and the top of the right support plate is connected to the upper right plate.

[0008] Preferably, the upper pressure chamber, the left pressure chamber and the right pressure chamber are all trapezoidal in shape, the upper support plate extends upward from the upper mounting surface to the upper pressure plate, the left support plate extends upward from the left mounting surface to the left pressure plate, and the right support plate extends upward from the right mounting surface to the right pressure plate.

[0009] Preferably, there are two upper support plates, which extend upward and obliquely from the middle of the upper mounting surface to the left and right sides of the upper pressure plate respectively; there are two left support plates, which extend obliquely from the middle of the left mounting surface to the left to the upper and lower sides of the left pressure plate respectively; there are two right support plates, which extend obliquely from the middle of the right mounting surface to the right to the upper and lower sides of the right pressure plate.

[0010] Preferably, the two upper support plates divide the upper pressure chamber into three cavities with triangular longitudinal sections, the two left support plates divide the left pressure chamber into three cavities with triangular longitudinal sections, and the two right support plates divide the right pressure chamber into three cavities with triangular longitudinal sections.

[0018] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0019] Example 1

[0020] like Figure 3 As shown, this embodiment provides an underground integrated pipe gallery with a pressure-bearing structure, including a base frame 1, the longitudinal section of the base frame 1 is rectangular, and the outer wall of the base frame 1 has an upper mounting surface 11, a left mounting surface 12 and a right mounting surface 13.

[0021] The existing underground integrated pipeline corridor design usually adopts rectangular cross-section, such as Figure 1 As shown in the figure, the outer walls on the left and right sides of the corridor need to bear the pressure from the surrounding fill, and the outer walls of the corridor will deform, as shown in the figure. Figure 2 As shown in the figure, once the outer wall deformation reaches a certain limit, it will have a serious adverse impact on the structure and function of the tunnel. To reduce the deformation of the tunnel under stress, the common practice is to increase the cross-sectional thickness to improve the rigidity of the tunnel sidewall. However, while increasing the cross-sectional thickness increases material costs, the effect of improving the rigidity of the tunnel sidewall is not significant enough. In other words, there is room for improvement in both economic cost and practical performance.

[0022] This embodiment also includes an upper pressure-bearing frame 2, a left pressure-bearing frame 3 and a right pressure-bearing frame 4, the upper pressure-bearing frame 2 includes an upper pressure-bearing plate 21 and an upper support plate 22, the left pressure-bearing frame 3 includes a left pressure-bearing plate 31 and a left support plate 32, the right pressure-bearing frame 4 includes a right pressure-bearing plate 41 and a right support plate 42, an upper pressure-bearing cavity 2a is formed between the upper pressure-bearing plate 21 and the upper mounting surface 11, the upper support plate 22 is located in the upper pressure-bearing cavity 2a and connects the upper pressure-bearing plate 21 and the upper mounting surface 11, a left pressure-bearing cavity 3a is formed between the left pressure-bearing plate 31 and the left mounting surface 12, the left support plate 32 is located in the left pressure-bearing cavity 3a and connects the left pressure plate 31 and the left mounting surface 12, a right pressure-bearing cavity 4a is formed between the right pressure-bearing plate 41 and the right mounting surface 13, the right support plate 42 is located in the right pressure-bearing cavity 4a and connects the right pressure plate 41 and the right mounting surface 13.

[0023] In this embodiment, the upper pressure frame 2, the left pressure frame 3 and the right pressure frame 4 are used to bear the pressure from the surrounding backfill, which avoids the pipe gallery from being unstable and deformed due to insufficient thickness and excessive span due to the direct contact of the single side wall with the backfill. In addition, since the upper pressure frame 2, the left pressure frame 3 and the right pressure frame 4 have a cavity structure, the economic cost is relatively low. The reasons are as follows: First, the setting of the upper pressure frame 2, the left pressure frame 3 and the right pressure frame 4 directly increases the support components above, on the left and on the right of the pipe gallery, avoiding the disadvantages of a single support of the side wall of the pipe gallery, which is mainly reflected in the addition of the upper pressure plate 21, the left pressure plate 31 and the right pressure plate 41, which changes the single support of the side wall of the pipe gallery into a double support of the side wall of the pipe gallery and each pressure plate, and then assists the support of the upper support plate 22, the left support plate 32 and the right support plate 42, which directly enhances the rigidity of the pipe gallery; secondly, due to the upper pressure cavity 2a, the left pressure cavity 3a and the right pressure cavity The pressure chambers 4a are all hollow structures, so under the condition of improving the same tunnel side wall stiffness, compared with the method of directly thickening the tunnel side wall, the hollow structure can save materials and reduce economic costs; finally, the upper pressure chamber 2a, the left pressure chamber 3a and the right pressure chamber 4a are respectively added with support plates 22, left support plates 32 and right support plates 42. The upper support plates 22, left support plates 32 and right support plates 42 have pressure-bearing and force-transmitting functions, which reduce the maximum bending moment deformation in the span of the upper pressure plate 21, the left pressure plate 31 and the right pressure plate 41, and prevent the occurrence of unstable deformation.

[0024] In this embodiment, the upper pressure-bearing chamber 2a is trapezoidal in shape, and the upper support plate 22 extends vertically upward from the upper mounting surface 11 to the upper pressure-bearing plate 21. The left pressure-bearing chamber 3a and the right pressure-bearing chamber 4a are both triangular in shape. The left support plate 32 extends upward and obliquely from the lower side of the left mounting surface 12 to the middle and upper portion of the left pressure-bearing plate 31, and the right support plate 42 extends upward and obliquely from the lower side of the right mounting surface 13 to the middle and upper portion of the right pressure-bearing plate 41. The upper pressure-bearing plate 21 includes a top plate 211 and two waist plates 212, which are respectively connected to the top plate 211 and the upper mounting surface 11. There are two upper support plates 22, and the tops of the two upper support plates 22 are respectively connected to the connection between the waist plates 212 and the top plate 211.

[0025] Since the upper pressure chamber 2a is trapezoidal in shape, the upper bottom position of the upper pressure plate 21 directly bears the pressure, and the pressure can be transmitted to the waist on both sides of the upper pressure plate 21, so that the upper pressure plate 21 can effectively support the pressure from above. The setting of the two upper support plates 22 also effectively supports the upper pressure plate 21, and effectively reduces the maximum bending moment deformation in the span of the upper pressure plate 21, thereby preventing deformation and instability.

[0026] In this embodiment, the left pressure plate 31 includes a left upper plate 311 and a left lower plate 312 connected to each other, the left upper plate 311 extends downwardly at an angle to the lower middle part of the left mounting surface 12, and the top of the left support plate 32 is connected to the left upper plate 311, and the right pressure plate 41 includes a right upper plate 411 and a right lower plate 412 connected to each other, the right upper plate 411 extends downwardly at an angle to the lower middle part of the right mounting surface 13, and the top of the right support plate 42 is connected to the right upper plate 411.

[0027] The triangular structure of the left and right pressure-bearing frames 3 and 4 significantly enhances their rigidity. Furthermore, in the left pressure-bearing frame 3, the left upper plate 311 primarily bears the fill pressure, while the left lower plate 312 bears significantly less of it. The pressure from the left upper plate 311 is largely distributed vertically downward, with the left lower plate 312 and left support plate 32 providing a force component to the pressure from the left upper plate 311. This provides excellent rigidity, minimizing the left fill pressure's impact on the left mounting surface 12, preventing deformation and instability and significantly enhancing support rigidity. Similarly, the right pressure-bearing frame 4 performs the same function for fill pressure from the right.

[0028] Example 2

[0029] like Figure 4 As shown, the difference between this embodiment and embodiment one is that the upper pressure chamber 2a, the left pressure chamber 3a and the right pressure chamber 4a are all trapezoidal in shape, the upper support plate 22 extends upward from the upper mounting surface 11 to the upper pressure plate 21, the left support plate 32 extends upward from the left mounting surface 12 to the left pressure plate 31, and the right support plate 42 extends upward from the right mounting surface 13 to the right pressure plate 41.

[0030] In this embodiment, there are two upper support plates 22, and the two upper support plates 22 extend upward and obliquely from the middle of the upper mounting surface 11 to the left and right sides of the upper pressure plate 21 respectively. There are two left support plates 32, and the two left support plates 32 extend obliquely from the middle of the left mounting surface 12 to the left to the upper and lower sides of the left pressure plate 31 respectively. There are two right support plates 42, and the two right support plates 42 extend obliquely from the middle of the right mounting surface 13 to the right to the upper and lower sides of the right pressure plate 41.

[0031] In this embodiment, the provision of the upper pressure frame 2, the left pressure frame 3, and the right pressure frame 4 directly increases the single support of the pipe gallery side wall into a dual support of the pipe gallery side wall and each pressure plate, and then assists the support function of the upper support plate 22, the left support plate 32, and the right support plate 42, directly enhancing the rigidity of the pipe gallery; the upper pressure chamber 2a, the left pressure chamber 3a, and the right pressure chamber 4a are all hollow structures, saving materials and reducing economic costs; the upper support plate 22, the left support plate 32, and the right support plate 42 have the functions of bearing pressure and transmitting force, reducing the maximum bending moment deformation in the span of the upper pressure plate 21, the left pressure plate 31, and the right pressure plate 41. Compared with the first embodiment, the two upper support plates 22 extend to the left and right sides of the upper pressure plate 21 in an inclined manner. In this way, the two support plates have less support force on the upper pressure plate 21 in the vertical direction, and their maximum bending moment deformation in the span of the upper pressure plate 21 is reduced less. In addition, since the left pressure frame 3 in the second embodiment adopts a trapezoidal shape, compared with the first embodiment, the bottom edge and waist position of the left pressure plate 31 are both subject to pressure from the backfill, and these pressures will be mostly transmitted to the left installation surface 12 of the corridor.

[0032] On the other hand, the second embodiment uses more materials.

[0033] In this embodiment, the two upper support plates 22 divide the upper pressure-bearing chamber 2a into three triangular cavities, the two left support plates 32 divide the left pressure-bearing chamber 3a into three triangular cavities, and the two right support plates 42 divide the right pressure-bearing chamber 4a into three triangular cavities. The triangular structure significantly enhances rigidity.

[0034] Example 3

[0035] like Figure 5 As shown, the difference between this embodiment and embodiment one is that the left pressure plate 31, the upper pressure plate 21 and the right pressure plate 41 are connected in sequence from left to right to form an arc-shaped plate, there are multiple left support plates 32, and the multiple left support plates 32 divide the left pressure chamber 3a into multiple cavities with triangular longitudinal sections, there are multiple upper support plates 22, and the multiple upper support plates 22 divide the upper pressure chamber 2a into multiple cavities with triangular longitudinal sections, and there are multiple right support plates 42, and the multiple right support plates 42 divide the right pressure chamber 4a into multiple cavities with triangular longitudinal sections.

[0036] In this embodiment, the provision of the upper pressure frame 2, the left pressure frame 3, and the right pressure frame 4 directly increases the single support of the pipe gallery side wall into a dual support of the pipe gallery side wall and each pressure plate, and then assists the support function of the upper support plate 22, the left support plate 32, and the right support plate 42, directly enhancing the rigidity of the pipe gallery; the upper pressure chamber 2a, the left pressure chamber 3a, and the right pressure chamber 4a are all hollow structures, saving materials and reducing economic costs; the upper support plate 22, the left support plate 32, and the right support plate 42 have the functions of bearing pressure and transmitting force, reducing the maximum bending moment deformation in the span of the upper pressure plate 21, the left pressure plate 31, and the right pressure plate 41. Since the upper support plate 22, the left support plate 32, and the right support plate 42 respectively divide the upper pressure chamber 2a, the left pressure chamber 3a, and the right pressure chamber 4a into multiple triangular cavities, this triangular structure greatly enhances the rigidity. In addition, compared with Example 1, since the left pressure plate 31, the upper pressure plate 21 and the right pressure plate 41 are connected in sequence from left to right to form an arc-shaped plate, the prefabrication cost of the arc-shaped plate is relatively high and the precision requirements of the arc-shaped plate are also high, so compared with Example 1, the economic efficiency will be worse.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
