Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a structure and method for supplementing a pile at a position with few piles. BACKGROUND

[0002] An engineering pile is a pile used in an engineering entity, which is a permanent pile constructed for building foundation treatment, and its construction quality and layout position directly affect the service life of a building. During building construction, the design and construction of an engineering pile need to be completed in a foundation pit, and after the construction of the engineering pile is completed, a bottom plate is laid and an upper building is constructed, and the position of the engineering pile cannot be moved or adjusted after the construction of the engineering pile is completed.

[0003] However, during the construction of the engineering pile, the actual construction position of the pile position occasionally deviates from the design position due to the influence of silt geological environment interference and variable site construction conditions, which results in the inability to find a corresponding pile position stress point during the construction of the upper building, so that there is no engineering pile to support at a position that needs to bear weight, which seriously affects the progress of the later construction and also affects the support effect of the building.

[0004] Therefore, how to timely and effectively supplement a pile when the position of the engineering pile deviates is a major test. After the construction of the foundation pit is completed, it is difficult to construct a new engineering pile, and it is also difficult to ensure that the supplement of the pile at the position with few piles has sufficient supporting capacity.

[0005] The above-mentioned defects are worth solving. SUMMARY

[0006] In order to solve the defect that there is no engineering pile to bear weight when the existing engineering pile deviates, and to enable the supplement of the pile at the position with few piles to have sufficient supporting strength, the present application provides a structure and method for supplementing a pile at a position with few piles.

[0015] On the other hand, a method for filling piles in a pile-scarce position, characterized in that, the method comprises the following steps:

[0016] S1, obtaining a pile-scarce position, and determining the positions of an offset engineering pile position and a first regular engineering pile position, so that the offset engineering pile position and the first regular engineering pile position are arranged on the left and right sides of a post-pile to be filled;

[0036] The present invention will now be further described with reference to the accompanying drawings and embodiments:

[0037] like Figures 1 to 5 As shown, in order to solve the problem of missing piles caused by the offset of existing engineering piles, and to enable the supplementary piles to have sufficient support strength and reduce the construction difficulty of the supplementary piles, the present invention provides a pile supplementary structure for the missing pile location of engineering piles and a construction method for the structure.

[0038] like Figure 1 As shown, this invention utilizes the offset engineering pile position 20 with a deviation in construction location and the adjacent conventional engineering pile to achieve the distribution of the supporting force of the supplementary engineering pile, ensuring the supporting foundation and strength of the supplementary engineering pile. Specifically, the supplementary pile structure at the location of the missing engineering pile includes the offset engineering pile position 20 and the first conventional engineering pile position 10a adjacent to the offset engineering pile position 20. A transverse ground beam 50 is erected between the offset engineering pile and the first conventional engineering pile position 10a, and the transverse ground beam 50 spans the location of the missing engineering pile. At the same time, the supplementary pile is erected on the upper side of the transverse ground beam 50, so that the supplementary pile is located directly above the location of the missing engineering pile.

[0039] The supplementary pile includes a supplementary pile body 30, with supplementary reinforcing bars 31 on both the left and right sides of the supplementary pile body 30. The distribution direction of the supplementary reinforcing bars 31 is consistent with the extension direction of the transverse ground beam 50. In addition, the supplementary reinforcing bars on the left and right sides are tied together by reinforcing bars with a zigzag bend. For example, 6ΦZ 16@50 (8) reinforcing bars are added to the left and right sides of the supplementary pile body 30 as supplementary reinforcing bars, and the supplementary reinforcing bars on both sides are connected by 8ΦZ25. In this embodiment, supplementary reinforcing bars are provided on the left and right sides of the supplementary pile body 30, and the left and right sides of the supplementary pile body 30 are respectively the offset engineering pile position 20 and the first conventional engineering pile position 10a obtained from the actual construction on site.

[0040] To increase the structural strength and support capacity of the transverse ground beam 50, a through-beam 42 is provided inside the transverse ground beam 50 of this invention. The two ends of the through-beam 42 are respectively connected to the offset engineering pile body 21 of the offset engineering pile position 20 and the conventional engineering pile body 11 of the first conventional engineering pile position 10a. Concrete is poured after the through-beam 42 is tied to the offset engineering pile position 20 and the first conventional engineering pile position 10a, which increases the structural strength and support capacity of the transverse ground beam 50.

[0041] Please see Figure 1 , Figure 2 The offset piles here are shifted to the left compared to the original designed pile positions, resulting in no piles supporting the superstructure at the designed pile positions. Therefore, the force distribution of the supplementary piles is achieved using the offset pile position 20 shifted to the left and the first conventional pile position 10a located to the right of the offset pile position 20. When this building structure is applied in a silty geological environment, the support effect of the supplementary piles will not be affected by the silty geological conditions. The first conventional pile here refers to the pile with an appropriate construction location, and the same applies to other subsequent conventional piles.

[0042] A base plate 60 is laid between the offset engineering pile position 20 and the first conventional engineering pile position 10a, and within the pile cap of the offset engineering pile position. The ground beam is located on the upper side of the base plate 60 between the offset engineering pile position 20 and the first conventional engineering pile position 10a. In this invention, the post-construction piles are installed on the base plate 60, making the construction process more convenient and unaffected by the underlying silty environment. In this embodiment, the thickness of the base plate 60 is 100mm.

[0043] exist Figure 1In the shown embodiment, the transverse beam 50 is not only supported on the offset pile site 20 and the first regular pile site 10a, but also extends to more regular pile sites to further distribute the support force of the post-pile. Specifically, one end of the transverse beam 50 extends to the second regular pile site 10b adjacent to the other side of the offset pile site 20, and the other end of the transverse beam 50 extends to the third regular pile site 10c beyond the first regular pile site 10a. Correspondingly, the through bar 42 also extends to the second regular pile site 10b and the third regular pile site 10c.

[0044] In the above embodiment, the support force of the post-pile is linearly distributed, i.e. the support force of the post-pile is distributed to the offset pile site 20, the first regular pile site 10a, and even the second regular pile site 10b and the third regular pile site 10c. In other embodiments, the support force of the post-pile can also be distributed in a plane. Specifically, the transverse beam 50 also intersects with one or more auxiliary beams (not shown in the figure, the same below), and the two ends of the auxiliary beam are connected to the fourth regular pile site 10d adjacent to the offset pile site 20. By intersecting the transverse beam 50 with the auxiliary beam, a support plane is formed, which can further distribute the support force of the post-pile to other regular piles.

[0045] In a specific implementation process, the auxiliary beam and the transverse beam 50 can intersect to form a cross, a T or a rice character. The auxiliary beam and the transverse beam 50 can also intersect to form a T, a factory character, etc. (at this time, one end of the auxiliary beam is connected with the transverse beam 50, and the other end is connected with the fourth regular pile site 10d adjacent to the offset pile site 20), which can distribute the support force of the post-pile in a plane using the surrounding regular piles.

[0046] Please refer to Figures 2 to 5 , the offset pile site 20 includes an offset pile body 21, which is located inside the offset pile pile cap 22, and the post-pile is fixed with the reinforcement assembly in the offset pile pile cap 22. In this embodiment, the surface of the offset pile pile cap 22 is calibrated with concrete to form an offset pile support body. In a specific embodiment, the offset pile support body is additionally provided with X-direction bottom reinforcement (such as Φ14@150 steel bars) and Y-direction bottom reinforcement (such as Φ12@150 steel bars).

[0047] In the implementation process, the steel bar assembly includes side longitudinal bars 41, side transverse bars 43, top transverse bars 44, bottom transverse bars 45, and bottom longitudinal bars 46. The side longitudinal bars 41 are distributed on the left and right sides inside the offset engineering pile cap 22. The side transverse bars 43 are distributed on the front and rear sides inside the offset engineering pile cap 22 and are tied and connected with the side longitudinal bars 41 on the front and rear side edges. The top transverse bars 44 are distributed on the top of the offset engineering pile cap 22 and are tied and connected with the through bars 42 inside the transverse girder 50. The bottom transverse bars 45 and the bottom longitudinal bars 46 are both distributed on the bottom of the offset engineering pile cap 22, and the bottom longitudinal bars 46 are tied and connected with the bottom transverse bars 45 and the side longitudinal bars 41 on the left and right side edges.

[0048] In the embodiment, the top end of the offset engineering pile body 21 is higher than the inner bottom wall of the offset engineering pile cap 22 by 100 mm. The force transmission between the support capacity of the offset engineering pile body 21 and the steel bar assembly inside the offset engineering pile cap 22 can make the offset engineering pile body 21 have a corresponding support capacity.

[0049] In the above structure, each conventional engineering pile position includes a conventional engineering pile body 11 located inside a conventional engineering pile cap 12, and the inside and surface of the conventional engineering pile cap 12 are poured with concrete to form a conventional engineering pile support body 13. The conventional engineering pile support body 13 here includes concrete forming part of the bottom plate 60. In one specific embodiment, the conventional engineering pile support body 13 is additionally provided with X-direction bottom bars (for example, Φ14@150 steel bars) and Y-direction bottom bars (for example, Φ12@150 steel bars).

[0050] The application also provides an engineering pile few-pile position pile supplementing method for realizing the above engineering pile few-pile position pile supplementing structure. The pile supplementing method specifically includes the following steps:

[0051] S1, first, an engineering pile few-pile position is obtained, and the reason for the few-pile position is determined according to the engineering pile few-pile position, and then an offset engineering pile position 20 is determined. Then, the position of a first conventional engineering pile position 10a is determined according to the position of the offset engineering pile position 20 and the position of the engineering pile few-pile position, so that the offset engineering pile position 20 and the first conventional engineering pile position 10a are distributed on the left and right sides of the to-be-supplemented pile.

[0052] In the specific construction design process, whether to perform horizontal expansion sharing or plane sharing of the support force of the to-be-supplemented pile is determined according to the engineering pile few-pile position, the design requirements of the upper building, and the design of the surrounding conventional engineering piles. If horizontal expansion sharing is required, a conventional engineering pile position on the left side of the offset engineering pile position is further selected as a second conventional engineering pile position 10b, and a conventional engineering pile on the right side of the first conventional engineering pile position 10a is further selected as a third conventional engineering pile position 10c. If plane sharing is required, a fourth conventional engineering pile position 10d (a conventional engineering pile position on the front and rear sides of the transverse girder 50) is further determined.

[0053] S2, erecting a transverse ground beam 50 between the offset engineering pile position 20 and the first conventional engineering pile position 10a, so that the transverse ground beam 50 spans the engineering pile less pile position.

[0054] In the specific construction process, the through bar 42 is first erected between the offset engineering pile position 20 and the first conventional engineering pile position 10a, and then the concrete is poured on the through bar 42 to form the transverse ground beam 50. Of course, when the through bar 42 is erected here, the through bar 42 needs to be bound to the reinforcement assembly in the offset engineering pile position 20 to realize the support transmission effect of the offset engineering pile position 20.

[0055] If the extension construction involving the second conventional engineering pile position 10b and the third conventional engineering pile position 10c is involved, the two ends of the transverse ground beam 50 need to pass through the offset engineering pile position 20 and the first conventional engineering pile position 10a respectively, so that one end of the transverse ground beam 50 extends to the second conventional engineering pile position 10b adjacent to the other side of the offset engineering pile, and the other end of the transverse ground beam 50 extends to the third conventional engineering pile position 10c on the other side of the first conventional engineering pile position 10a after passing through the first conventional engineering pile position 10a.

[0056] In addition, if the planar distribution needs to be carried out by using the fourth conventional engineering pile position 10d, after the transverse through bar 42 is erected, the erection process of the auxiliary bar is also included: specifically, the auxiliary bar is erected so that the auxiliary bar intersects with the through bar 42, and the two ends of the auxiliary bar are connected to the fourth conventional engineering pile on the side of the offset engineering pile position 20.

[0057] S3, erecting a post-pile on the transverse ground beam 50, so that the post-pile is located directly above the engineering pile less pile position.

[0058] The specific construction process of the post-pile is similar to that of the engineering pile structure on the side of the conventional engineering pile position, which will not be described here.

[0059] The present application utilizes the first conventional engineering pile position 10a (and possibly the second conventional engineering pile position 10b, the third conventional engineering pile position 10c, and the fourth conventional engineering pile position 10d) and the construction offset offset engineering pile position 20 to horizontally distribute (and possibly planarly distribute) the support force of the post-pile, which not only solves the problem of engineering pile less pile, but also reduces the construction difficulty of the post-pile and saves the construction period.

[0060] It should be understood that those skilled in the art can make improvements or changes according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the present application.

[0061] The patent of the application is exemplarily described above in combination with the drawings, and it is obvious that the implementation of the patent of the application is not limited by the above-mentioned mode, as long as various improvements are made by adopting the method concept and technical scheme of the patent of the application, or the concept and technical scheme of the patent of the application is directly applied to other occasions without improvement, which are all within the protection scope of the patent of the application.
