Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a bridge and channel combined structure. Background Art

[0002] As urban road networks become increasingly dense, the construction or renovation and expansion of roads and bridges are subject to more and more constraints; three-dimensional traffic forms are often formed at road intersections, specifically with elevated bridges on the upper level and ground roads on the lower level.

[0003] Due to the complexity of urban roads, there is often a certain elevation difference between two intersecting roads, making it difficult to set up the intersection. In this case, according to the existing treatment method, the upper road is usually set as an elevated bridge, and the lower road is usually set as a ground road, semi-underground passage, underground passage, etc.; that is, the construction plan of the upper and lower structures can be built separately or together. When separate construction is adopted, the upper and lower structures are completely independent, and the design and construction are simple, but more land is occupied, the project scale is large, and the cost is high; when combined construction is adopted, less land is occupied, the project scale is small, and the cost is low, but the design and construction plan is more difficult.

[0004] However, the existing technical solutions still retain the complete bridge piers and foundation components, and most of these lower components use the side walls or top and bottom plates of the underground passage as support. Therefore, when the bridge substructure is set in the passage, it will occupy the internal space of the passage, resulting in an increase in the scale of the passage project, the amount of construction earth excavation, and the area occupied; and when the bridge substructure is set on the top and bottom plates of the passage, it will have an adverse effect on the stress on the top and bottom plates of the passage, resulting in an increase in the size of the top and bottom plates, an increase in the amount of reinforced concrete, and may also cause uneven settlement and structural cracking, affecting the safety and durability of the structure; and there are problems such as low degree of joint construction, few shared components, and high overall building height, which fail to fully utilize the building space.

[0042] In an embodiment of the utility model, the channel component 2 is arranged along the first direction, and integrated wall piers 4 are provided at corresponding positions on both sides of the channel component 2, so as to support the bridge arranged above the channel component 2 and distributed along the second direction. This support method sets the walls on both sides of the channel component 2 as integrated wall piers 4 to avoid using additional space to make bridge piers. Under the premise of ensuring the use requirements, the technical effect of saving construction materials and not expanding the scale of the project is achieved.

[0043] Compared with the prior art, the combined structure of bridge and channel provided in the embodiment of the utility model provides integrated wall piers 4 on both sides of the channel component 2 distributed along the first direction to support the bridge distributed along the second direction, thereby achieving the technical effect of saving construction materials and not expanding the scale of the project while ensuring the use requirements.

[0044] In an optional implementation manner of this embodiment, refer to Figure 3 or Figure 4 The integrated wall pier 4 includes a wall pier body 41 and a support assembly 43 . The bottom of the wall pier body 41 is connected to the channel assembly 2 , and the top of the wall pier body 41 is connected to the bridge through the support assembly 43 .

[0045] Specifically: there are at least two wall-type pier bodies 41, and the two wall-type pier bodies 41 are arranged on both sides of the channel component 2, which not only serve as the enclosing walls of the channel component 2, but also are supported at the bottom of the bridge through the support component 43 on the top of the wall-type pier body 41.

[0046] Preferably, the wall-type pier body 41 can be a reinforced concrete structure, which mainly supports the bridge, resists the lateral fill 6 pressure outside the channel component 2, and separates the space; and its height varies with the design elevation of the bridge superstructure.

[0047] Further, refer to Figure 3 or Figure 4 There are multiple support assemblies 43, and the multiple support assemblies 43 are spaced apart and distributed on the top of the wall-type pier body 41. The multiple support assemblies 43 support the bridge together, and their support heights match the support heights of other piers 5.

[0048] Specifically: a plurality of support assemblies 43 are provided, and the plurality of support assemblies 43 are spaced apart and arranged in a matrix shape, and each support assembly 43 is connected to the bottom of the bridge; a certain number of support assemblies 43 are arranged in a matrix shape to meet the support requirements for the bridge.

[0050] Specifically, the pad stone 431 is located at the top of the wall pier body 41, and is cast together with the expanded head of the wall pier body 41, corresponding to the main beam position of the bridge superstructure. The main function is to adjust the installation elevation of the support 432 so that the main beam can be placed at a predetermined position.

[0051] The bearing 432 is generally a finished product bearing, and its main function is to transfer the vertical load of the bridge superstructure.

[0052] Further, refer to Figure 3 The integrated wall pier 4 also includes a stopper 42, which is connected to the top of the wall pier body 41, and is used to provide side position limiting support for the bridge.

[0053] Specifically: the stoppers 42 are located at the top ends of the wall-type pier body 41, leaving a certain horizontal gap between the stoppers 42 and the main beams of the bridge superstructure; their main function is to prevent the bridge superstructure from falling under the action of an earthquake.

[0054] In an optional implementation manner of this embodiment, an expanded pier cap is provided on the top of the wall-type pier body 41 .

[0055] Specifically: both ends of the integrated wall pier 4 are provided with expanded pier caps, and the width of the expanded pier caps meets the laying length requirement of the bridge superstructure.

[0056] It should be noted that an expanded pier cap is provided on the top of the integrated wall pier 4 to enlarge the top area of ​​the integrated wall pier 4, and more cushion stones 431 and a production 432 provided on each cushion stone 431 can be provided on the top.

[0057] In an optional implementation manner of this embodiment, refer to Figure 1 or Figure 2 The channel assembly 2 includes a channel body 21 and a cushion layer 22 laid at the bottom of the channel body 21 , and the channel body 21 and the cushion layer 22 are distributed along a first direction; the channel body 21 is connected to the wall pier body 41 .

[0058] Specifically: a cushion layer 22 is laid at the bottom of the channel body 21. The channel body 21 is generally a reinforced concrete slab structure set on the foundation. When the soil of the foundation is poor, a pile foundation can be set at the bottom; the cushion layer 22 is generally crushed stone or gravel, which is set under the channel body 21 and its main function is to level the foundation.

[0059] Furthermore, the combined structure of the bridge and the channel also includes a channel side wall 3 , which is connected to the channel body 21 , and the lower part of the channel side wall 3 is buried in the fill 6 .

[0060] Specifically, the channel side walls 3 are arranged on both sides above the channel body 21 of the non-under-bridge space, and are generally reinforced concrete wall structures, which mainly play the role of resisting the lateral pressure of the fill 6 outside the channel and separating the space.

[0061] Preferably, the thickness of the channel side wall 3 is consistent with the thickness of the wall-type pier body 41 .

[0062] Further, refer to Figure 1 The channel body 21 and the channel side walls 3 on both sides thereof form a groove structure with a U-shaped cross section.

[0063] Specifically: the channel formed by the channel body 21 and the channel side walls 3 on both sides thereof and the integrated wall pier 4 is a U-shaped trough structure, and is preferably a semi-underground structure.

[0064] In an optional implementation manner of this embodiment, refer to Figure 1 or Figure 2 The bridge includes a bridge deck body 1 and a plurality of bridge piers 5 connected to the bridge deck body 1 , and the bridge deck body 1 is connected to the integrated wall pier 4 .

[0065] Specifically: the bridge pier 5 can be in the form of a column pier, a portal pier, a vase pier, etc. depending on the actual situation; its main function is to support the superstructure of the bridge and transfer the internal force of the superstructure to the foundation.

[0066] Preferably, the bridge deck body 1 is the same as the conventional bridge superstructure, and the width and layout of the bridge deck body 1 need to be determined in combination with the route design. Its standard span needs to be equal to the distance between the center lines of the channel side walls to ensure that the bridge deck body 1 can be placed on the integrated wall pier 4; and the form of the bridge deck body 1 should preferably use a structure with a smaller beam height.

[0067] The construction process includes:

[0068] Step 1: Excavate the channel foundation pit and construct conventional bridge piers simultaneously.

[0069] Step 2: construct the channel body 21, the channel side wall 3 and the integrated wall pier 4 in sequence.

[0070] Step 3: Backfill the wall side with soil 6.

[0071] Step 4: construct the cushion stone 431 on the top of the wall pier body 41 and install the support 432.

[0072] Step 5: erecting the bridge superstructure, that is, erecting the bridge deck body 1, and then completing the bridge deck system construction.

[0073] Step 6: Construct related ancillary facilities and finally complete the bridge.

[0074] This embodiment combines the bridge and the passage, and sets an integrated wall pier 4 in the structure to support the bridge, so that it has the following advantages:

[0075] The lower structure at the intersection of the bridge and the passage is simplified, that is, the bridge is supported by the integrated wall pier 4 and the bridge pier 5, without the need to set up an additional pier body, which reduces the construction workload to a certain extent and helps to shorten the construction period.

[0076] The bridge superstructure is supported on the integrated wall pier 4, which is conducive to reducing the span of the bridge structure, thereby reducing the height of the bridge deck body 1, and further reducing the elevation of the route longitudinal section, thereby reducing the project scale and saving the project cost.

[0077] There is no need to set up a bridge support structure inside the channel, which reduces the use of engineering materials and improves the utilization rate of the internal space of the channel.

[0078] It effectively avoids setting up the bridge substructure close to the channel side wall 3, which not only wastes space and construction materials, but also leads to the problems of force coupling and construction intersection, and further improves the reliability and safety of the structure.

[0079] The overall vertical force transmission path of the combined structure is more reasonable and concise, which helps to ensure the stress-bearing performance of the structure.

[0080] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referenced to each other; the above embodiments in this specification are only used to illustrate the technical solution of the utility model, rather than to limit it; although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that: it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
