Abstract
Description
Technical Field
[0001] This application relates to the field of building construction technology, and in particular to a support structure. Background Technology
[0002] In modern society, in pursuit of maximizing land use efficiency, construction companies often place basements close to the land boundary, leaving extremely limited space for foundation pit support design. While using support piles (or diaphragm walls, etc.) combined with anchor cables and soil nails solves the stress problem, many regions have strict restrictions on the use of anchor cables or soil nails, meaning the support structure cannot extend beyond the land boundary. However, when the foundation pit is deep, eliminating anchor cables or soil nails and directly using cantilever support structures can lead to excessive displacement, which can damage surrounding pipelines and buildings, and also does not meet regulatory requirements.
[0003] Conventional inclined piles solve the problem of anchor cables extending beyond the land boundary line, but they bring new problems. When the inclined piles extend from the top of the capping beam into the foundation pit, if the designed position of the inclined piles passing through the bottom of the foundation pit is outside the basement area, the construction space between the support piles and the basement exterior walls will be large, resulting in excessive earthwork excavation and poor economic efficiency. If the earthwork excavation is deliberately reduced, the construction space between the support piles and the basement exterior walls will be small, and the inclined piles will pass through the basement exterior walls and floor slab, occupying a lot of basement construction space and affecting the construction of the basement floor slab and exterior walls. Furthermore, the subsequent removal of the inclined support piles within the basement area will also generate a large amount of construction waste, which will have an adverse impact on the environment. Utility Model Content
[0004] This application aims to solve one of the aforementioned technical problems in the prior art. Therefore, embodiments of this application provide a support structure.
[0005] According to an embodiment of this application, a support structure is provided, including a plurality of vertical support piles, wherein the plurality of vertical support piles are spaced apart.
[0006] Several inclined support piles are arranged at intervals;
[0007] A connecting beam is used to connect the top ends of the vertical support pile and the inclined support pile together, wherein one end of the inclined support pile is located on one side of the vertical support pile, and the other end of the inclined support pile is inclined towards the interval between two adjacent vertical support piles.
[0008] The aforementioned support structure has at least the following beneficial effects: When using the support structure of this application, the top of the inclined support pile is close to the land boundary line, and the bottom of the inclined support pile is close to the vertical support pile (that is, inclined towards the direction of the foundation pit), which effectively utilizes the space between the land boundary line and the foundation pit, and will not exceed the land boundary line range, thus avoiding disputes. It can also avoid the problem of the inclined support pile extending into the foundation pit and affecting earthwork excavation and basement construction. Since the top of the inclined support pile does not start to slope into the foundation pit from the top of the connecting beam like conventional inclined piles, but only slopes into the pit from between the vertical support pile and the land boundary line, it occupies less space in the foundation pit. Even in some areas where regulations restrict anchor cables (or soil nails) from extending beyond the land boundary line, the inclined piles can be constructed in soil that does not require excavation, without affecting earthwork excavation and basement construction at all.
[0009] According to the support structure described in the embodiments of this application, an inclined support pile is provided between two adjacent vertical support piles, so that one end of the inclined support pile is on one side of the vertical support pile, and the other end of the inclined support pile is on the other side of the vertical support pile.

The top of the vertical support pile is fixedly connected to the first cap beam to form a vertical support row, and the top of the inclined support pile is fixedly connected to the second cap beam to form an inclined support row.
[0011] According to the support structure described in the embodiments of this application, the connecting beam further includes a cap beam, and the two sides of the cap beam are respectively connected to the first cap beam and the second cap beam, wherein the first cap beam and the second cap beam are at the same horizontal height.
[0012] According to the support structure described in the embodiments of this application, at least two rows of inclined support rows are provided, and the two rows of inclined support rows are spaced apart in the vertical direction. The second crown beam of the inclined support row closest to the first crown beam is connected to the first crown beam through the cap beam, and the second crown beams of two adjacent rows of inclined support rows are connected through the cap beam.
[0013] According to the support structure described in the embodiments of this application, the tops of all the inclined support rows are at the same horizontal height as the tops of the vertical support rows.
[0014] According to the support structure described in the embodiments of this application, the cap beam, the first crown beam, and the second crown beam are all cast-in-place concrete structures.
[0015] According to the support structure described in the embodiments of this application, the included angle between the inclined support pile and the vertical support pile is set to 30°-60°.
[0016] According to the support structure described in the embodiments of this application, the vertical support piles and the inclined support piles are all one of the following: cast-in-place piles, precast pipe piles, precast square piles, steel pipe piles, and SMW method piles.
[0017] According to the support structure described in the embodiments of this application, the diameter of the vertical support pile is larger than that of the inclined support pile, and the ratio of the interval between two adjacent vertical support piles to the diameter of the inclined support pile is 1-1.2.
[0018] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0030] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.
[0031] Reference Figures 1 to 6 The support structure provided in this application embodiment includes several vertical support piles 100, inclined support piles such as rods 200, and connecting beams.
[0032] The structure includes several vertical support piles 100 spaced apart and several inclined support piles 200 spaced apart. The vertical support piles 100 are arranged in a linear array, and the inclined support piles 200 are also arranged in a linear array, with the same array direction. A connecting beam is used to connect the top ends of the vertical support piles 100 and the inclined support piles 200 together to form a complete support structure. One end of the inclined support pile 200 is located on one side of the vertical support pile 100, and the other end of the inclined support pile 200 is inclined towards the vertical support pile 100.
[0033] When using the support structure of this application, the top of the inclined support pile 200 is close to the land boundary line, and the bottom of the inclined support pile 200 is close to the interval between two adjacent vertical support piles 100 (i.e., inclined towards the excavation pit). This effectively utilizes the space between the land boundary line and the excavation pit, and does not exceed the land boundary line, avoiding disputes and preventing the inclined support pile 200 from extending into the excavation pit, affecting earthwork excavation and basement construction. Since the top of the inclined support pile 200 does not start from the top of the connecting beam into the excavation pit like conventional inclined piles, such as... Figure 3 and Figure 4As shown, the inclined piles only slope into the pit from between the vertical support pile 100 and the land boundary line, thus occupying less space in the foundation pit. In some areas, where regulations restrict anchor cables (or soil nails) from extending beyond the land boundary line, inclined piles can even be constructed in soil that does not require excavation, without affecting earthwork excavation or basement construction.
[0034] In some embodiments, such as Figure 1 , 2 As shown in Figures 5 and 6, an inclined support pile 200 is provided between two adjacent vertical support piles 100, so that one end of the inclined support pile 200 is on one side of the vertical support pile 100 and the other end of the inclined support pile 200 is on the other side of the vertical support pile 100. That is, the end of the inclined support pile 200 passes through the gap between two adjacent vertical support piles 100, which makes the entire support structure occupy less space and is suitable for situations where the space between the land boundary line and the foundation pit is not large.
[0035] In some embodiments, the connecting beam includes a first capping beam 300 and a second capping beam 400. The top of the vertical support pile 100 is fixedly connected to the first capping beam 300 to form a vertical support row, and the top of the inclined support pile 200 is fixedly connected to the second capping beam 400 to form an inclined support row. The formation of the inclined and vertical support rows can improve the overall structural rigidity and facilitate better connection between the subsequent vertical support pile 100 and the inclined support pile 200.
[0036] In some embodiments, the connecting beam further includes a cap beam 500, with a first cap beam 300 and a second cap beam 400 connected to its two sides, respectively, wherein the first cap beam 300 and the second cap beam 400 are at the same horizontal level. This facilitates adjustment of the horizontal level and flatness of the support structure.
[0037] In some embodiments, such as Figure 5 and Figure 6 As shown, at least two rows of inclined support piles are set up, with the two rows of inclined support piles spaced apart in the vertical direction. The second capping beam 400 of the inclined support pile closest to the first capping beam 300 is connected to the first capping beam 300 through a cap beam 500. The second capping beams 400 of adjacent rows of inclined support piles are connected through cap beams 500. When the stress of one row of inclined support piles 200 is insufficient, more rows of inclined support piles 200 can be constructed, as long as they are within the red line area. Moreover, the angle of the inclined support piles 200 can be adjusted according to the stress, making the arrangement quite flexible.
[0038] In this embodiment of the application, the top of all the inclined support rows is at the same horizontal level as the top of the vertical support rows.
[0039] In some specific embodiments, the cap beam 500, the first cap beam 300, and the second cap beam 400 are all cast-in-place concrete structures. Cast-in-place structures are easy to construct and flexible to adjust, resulting in cap beam 500 and cap beams with high rigidity, which can effectively control the deformation and displacement of the support structure.
[0040] In some embodiments, the included angle between the inclined support pile 200 and the vertical support pile 100 is set to 30°-60°. The size and inclination angle of the inclined support pile 200 can be adjusted according to design requirements, providing high flexibility.
[0041] The vertical support pile 100 has a larger diameter than the inclined support pile 200, and the ratio of the interval between two adjacent vertical support piles 100 to the diameter of the inclined support pile 200 is 1-1.2.
[0042] In some specific embodiments, the vertical support pile 100 and the inclined support pile 200 are one of the following: cast-in-place piles, precast pipe piles, precast square piles, steel pipe piles, and SMW method piles. Unlike ordinary anchor cables or soil nails, they do not require the grout to reach strength before the excavation of the foundation pit. In addition, SMW method piles can recycle steel, which is economical and environmentally friendly.
[0043] In this embodiment, the inclined support piles 200 have high stiffness and make a significant contribution to the safety of the foundation pit. Therefore, the pile diameter, pile spacing, and pile length of the front row of piles can be optimized. This results in a lower cost than the ordinary single-row vertical pile with anchor cables (or soil nails) scheme, which has a positive impact on project profitability.
[0044] Because the top of the inclined support pile 200 does not start from the top of the capping beam and slope into the pit like conventional inclined piles, but only slopes into the pit between the vertical support pile 100 and the land boundary line, it occupies less space in the pit. In some areas, where regulations restrict anchor cables (or soil nails) from extending beyond the land boundary line, the inclined piles can even be constructed in soil that does not require excavation, without affecting earthwork excavation or basement construction.
[0045] It is common for conventional foundation pit anchor cables to be 20-40 meters long. Therefore, the anchor cables used for support are very likely to exceed the land boundary line. However, when the vertical support piles 100 meters away from the land boundary line are relatively small, the support technology in this application can solve the foundation pit safety problem.
[0046] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
