Description

Technical Field

[0001] The utility model relates to the technical field of buttresses, in particular to a low-load buttress on a non-paved ground. Background Art

[0002] A pier refers to a pier built to prevent the displacement of pipes and their accessories caused by thermal expansion of the pipes and external loads. It provides stable support for pipes and other facilities, evenly distributes the pressure on the pipes to the foundation, and prevents them from deforming, sinking or being damaged due to their own weight or external pressure, thereby ensuring that the pipes remain stable in a specific position and avoid displacement during operation.

[0003] If piers are installed in soft soil, due to the loose soil's weak bearing capacity, they are prone to sinking under their own weight and the weight of the objects they support. Furthermore, due to the uneven nature of the loose soil, settlement can vary from location to location, leading to uneven settlement of the piers. Uneven settlement imposes additional stress on the piers and the supported facilities, potentially causing them to crack and tilt, and even lead to serious consequences such as rupture of supported pipelines and structural instability. This can cause the pipelines and structures supported by the piers to tilt, compromising their functionality. Furthermore, under the influence of external loads (such as wind and water impact) or minor geological activity, the piers may shift on the loose soil. This can alter the pier's position, undermining the stability of the entire support system, and potentially causing misalignment, deformation, or even damage to the supported facilities.

[0004] Therefore, prior to installing buttresses, it is generally necessary to pre-treat and compact the loose soil to maximize its density and minimize the possibility of subsequent settlement. At the same time, the location of the buttresses must be accurately measured and positioned to ensure they are in the correct position and can effectively perform their supporting functions.

[0005] However, problems such as cracks, settlement or displacement are still prone to occur in the future. It is necessary to regularly check the condition of the piers and ensure the stability of the piers by additional compaction of the loose soil, reinforcement of the foundation, etc. The instability of the loose soil increases the frequency of maintenance of the piers to a certain extent. Utility Model Content

[0006] The purpose of the utility model is to provide a low-load pier for non-paved ground, solve the problem of poor supporting performance of piers built on loose soil, improve the supporting performance of piers built on loose soil, and reduce the frequency of subsequent maintenance of piers.

[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0008] A low-load pier for non-paved ground includes a steel plate arranged in a foundation pit and connected to a bracket, the bottom of the steel plate is provided with longitudinal and transverse steel wire meshes in contact with the foundation pit, and a plurality of vertical supports connected to the longitudinal and transverse steel wire meshes and the foundation pit, the longitudinal and transverse steel wire meshes are sleeved on the outside of the vertical supports, the vertical supports are provided with a plurality of transverse supports and transverse steel wire meshes connected to the transverse supports, and backfill materials are provided between adjacent transverse steel wire meshes and between the transverse steel wire meshes and the steel plate.

[0009] Furthermore, the cross brace is provided with steel nails connected to the transverse steel wire mesh.

[0010] Furthermore, reinforcing ribs are provided between the horizontal braces and the vertical braces.

[0011] Furthermore, a plurality of first bolts are provided on the foundation pit, a plurality of first adjustment holes for the first bolts to pass through are provided on the steel plate, and the ends of the first bolts are threadedly connected with first nuts in contact with the steel plate.

[0012] Furthermore, a plurality of support beams are provided on the top and bottom of the longitudinal and transverse steel wire mesh panels, and both ends of the support beams are connected to the vertical supports respectively.

[0013] Furthermore, the support beam at the top is provided with a plurality of second bolts, the steel plate is provided with a plurality of second adjustment holes, and the ends of the second bolts are threadedly connected with second nuts in contact with the steel plate.

[0014] Furthermore, the cross section of the vertical support is L-shaped.

[0015] Furthermore, the backfill material is crushed stone soil.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By connecting the remaining pier components except the steel plates in advance in the factory, there is no need to lay transverse wire mesh layer by layer on site, which further improves the efficiency of pier construction. The foundation pit is pre-excavated at the designated location on site, and the pier is placed in the foundation pit as a whole except for the steel plates, so that the longitudinal and transverse wire meshes are in contact with the side walls of the foundation pit. The longitudinal and transverse wire meshes ensure full contact between the pier and the foundation pit, and the longitudinal and transverse wire meshes are fixed with vertical braces to avoid gaps between the pier and the foundation pit, which would cause large deformation under pressure. At the same time, the friction between the transverse wire mesh and the loose soil and backfill material further prevents the pier from sinking, thereby improving the supporting performance of the pier built on the loose soil and reducing the frequency of subsequent maintenance of the pier.

[0018] 2. Fill the foundation pit with backfill material, which falls into the foundation pit through the holes of the transverse steel wire mesh until the foundation pit is backfilled. Finally, the steel plate is placed on the top of the foundation pit to realize the construction of the pier. At the same time, since backfill material is provided between the transverse steel wire meshes and between the transverse steel wire meshes and the steel plates, the steel plates serve as panels and the transverse steel wire meshes serve as reinforcements to form a reinforced soil structure with the backfill material. The friction between the transverse steel wire meshes and the backfill material is utilized to limit and improve the deformation conditions of the soil and improve the engineering performance of the soil, thereby improving the supporting performance of the pier built on loose soil and reducing the frequency of subsequent maintenance of the pier. In addition, the pier is embedded in the ground as a whole to reduce the impact of external loads (such as wind force, water impact force, etc.) on the pier and avoid displacement of the pier on the loose soil.

[0038] Example 1

[0039] The utility model provides a low-load pier for non-paved ground, such as Figure 1 、 Figure 2 and Figure 3 As shown, by connecting the remaining pier components except the steel plate 3 into a whole in advance in the factory, there is no need to lay the transverse steel wire mesh 7 layer by layer on site, which further improves the efficiency of building the pier. Subsequently, the foundation pit 1 is pre-excavated at the designated location on site, and the pier except the steel plate is placed in the foundation pit 1 as a whole, so that the longitudinal and transverse steel wire meshes 4 are in contact with the side walls of the foundation pit 1. The loose soil flowing back from the foundation pit 1 is intercepted by the longitudinal and transverse steel wire meshes 4, and the longitudinal and transverse steel wire meshes 4 are fixed in conjunction with the vertical supports 5 to avoid the existence of a gap between the pier and the foundation pit 1, which will cause a large deformation after bearing pressure. At the same time, the friction between the transverse steel wire mesh 4 and the loose soil and backfill material 8 further prevents the pier from sinking, thereby improving the supporting performance of the pier built on the loose soil and reducing the frequency of subsequent maintenance of the pier.

[0040] Then, backfill material 8 is filled into the foundation pit 1. The backfill material 8 falls into the foundation pit through the holes of the transverse steel wire mesh 7 until the foundation pit 1 is backfilled. Finally, the steel plate 3 is placed on the top of the foundation pit 1 to realize the construction of the pier. At the same time, since backfill material 8 is provided between the transverse steel wire meshes 7 and between the transverse steel wire meshes 7 and the steel plate 3, the steel plate 3 is used as a panel and the transverse steel wire mesh 7 is used as a reinforcement to form a reinforced soil structure with the backfill material 8. The friction between the transverse steel wire mesh 7 and the backfill material 8 is used to limit and improve the deformation conditions of the soil and improve the engineering performance of the soil, thereby improving the supporting performance of the pier built on loose soil and reducing the frequency of subsequent maintenance of the pier. In addition, the pier is embedded in the ground as a whole to reduce the influence of external loads (such as wind force, water impact force, etc.) on the pier and avoid displacement of the pier on the loose soil.

[0041] Example 2

[0042] Based on Example 1, Figure 2 、 Figure 3 and Figure 4As shown, the cross brace 6 is provided with steel nails 9 connected to the transverse steel wire mesh 7, which increases the contact area between the transverse steel wire mesh 7 and the cross brace 6, improves the vertical bearing capacity of the transverse steel wire mesh 7, further avoids the phenomenon of pier sinking, and thus improves the supporting performance of the pier built on loose soil, and reduces the frequency of subsequent maintenance of the pier; reinforcing ribs 10 are provided between the cross brace 6 and the vertical brace 5, which transfer the load force received by the cross brace 6 to the vertical brace 5, further strengthen the bearing capacity of the pier, and thus improve the supporting performance of the pier built on loose soil, and reduce the frequency of subsequent maintenance of the pier; a plurality of support beams 14 are provided on the top and bottom of the longitudinal and transverse steel wire mesh 4, respectively, and the support beams 14 are provided with a plurality of support beams 14. The two ends are respectively connected to the vertical support 5, bearing the lateral load force of the longitudinal and transverse steel wire meshes 4, improving the stability of the overall structure, avoiding the large-scale backflow of loose soil and mixing with the backfill material 8, thereby improving the supporting performance of the pier built on the loose soil, and reducing the frequency of subsequent maintenance of the pier; the cross-section of the vertical support 5 is L-shaped, one side of which is connected to the longitudinal and transverse steel wire meshes 4, and the other side serves as a reinforcing side, bearing the lateral force of the longitudinal and transverse steel wire meshes 4 on the vertical support 5, thereby improving the stability of the overall structure, avoiding the large-scale backflow of loose soil and mixing with the backfill material 8, thereby improving the supporting performance of the pier built on the loose soil, and reducing the frequency of subsequent maintenance of the pier.

[0043] Example 3

[0044] Based on Example 2, Figure 1 、 Figure 5 and Figure 6 As shown, a plurality of first bolts 11 are pre-installed in the foundation pit 1. After the buttress is placed in the foundation pit 1, the first adjustment holes 12 provided on the steel plate 3 are aligned with the first bolts 11. The first bolts 11 are then passed through the first adjustment holes 12, and the first nuts 13 are tightened at the ends of the first bolts 11 so that the first nuts 13 are in contact with the steel plate 3. This fixes the buttress in the foundation pit 1 and bears the lateral load force on the buttress, thereby improving the supporting performance of the buttress when built on loose soil and reducing the frequency of subsequent maintenance of the buttress.

[0045] After backfilling the backfill material, move the position of the steel plate 3 so that the several second adjustment holes 16 on the steel plate 3 correspond to the several second bolts 15 provided on the top support beam 14, and then pass the second bolts 15 through the second adjustment holes 16, and tighten the second nuts 17 so that the second nuts 17 are in contact with the steel plate 3, thereby limiting the movement of the transverse steel wire mesh 7 and the longitudinal steel wire mesh 4 on the foundation pit 1, bearing the lateral load force on the pier, thereby improving the supporting performance of the pier built on loose soil and reducing the frequency of subsequent maintenance of the pier.
