Description

Technical Field

[0001] This utility model relates to the field of road repair technology, specifically to a collaborative support structure for road collapse repair. Background Technology

[0002] Road collapses (such as potholes, slope landslides, and riverbed landslides) are often sudden and disruptive to traffic. Existing repair methods often utilize rigid concrete or gabion structures. While rigid concrete offers high stability, it lacks flexibility, making it prone to localized damage under significant impacts and poor at dispersing impact forces. Pure gabion structures, although possessing some flexibility and permeability, lack sufficient overall rigid support capacity and are prone to excessive deformation under long-term loads. Therefore, existing repair structures suffer from the problem of failing to balance support strength and stability. Utility Model Content

[0003] To address the aforementioned problems in the prior art, this utility model provides a collaborative support structure for road collapse repair, which solves the problem that existing repair structures cannot simultaneously ensure support strength and stability.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A collaborative support structure for road collapse repair is provided, comprising two concrete piles, a gabion retaining wall fixed between the two concrete piles, and anchor rods anchored at both ends to the middle of the two concrete piles respectively within the gabion retaining wall; a concrete support frame beam is provided on one side of the end face of the gabion retaining wall, the concrete support frame beam comprising two inverted L-shaped columns, the bent ends of the two columns being fixedly connected to the two concrete piles respectively, and the two columns being fixedly connected by a crossbeam.

[0005] The beneficial effects of this scheme are as follows: concrete piles provide robust rigid support, while gabion retaining walls adapt to minor foundation deformations through their flexibility and disperse load impacts. By combining rigid concrete piles with flexible gabion retaining walls, a balance between high strength and high stability is achieved in road collapse repair. At the same time, the introduction of anchor rods and concrete support frame beams connects the concrete piles, gabion retaining walls, and concrete support frame beams into a whole, significantly improving the structure's resistance to overturning and sliding, and solving the problem that existing repair structures cannot simultaneously achieve both support strength and stability.

[0006] Furthermore, both ends of the anchor rod pass through two concrete piles and are threadedly connected to the anchor nuts. This threaded connection allows for an adjustable and secure bond between the anchor rod and the concrete piles, facilitating fine-tuning of tension during installation and ensuring the anchor rod remains pre-tightened under load. This enhances the structure's dynamic adaptability, prevents loosening of the connection due to foundation settlement or impact, and thus improves durability.

[0007] Furthermore, rectangular washers are installed at the connection points of the two anchor nuts and the two concrete piles. The rectangular washers effectively increase the stress area, reduce the concentrated pressure of the nuts on the surface of the concrete piles, prevent the concrete from crushing or cracking, and extend the service life of the connection points.

[0008] Furthermore, each concrete pile and gabion retaining wall comprises a reinforcing cage and multiple gabion units; the reinforcing cage is fixedly connected to the gabion units located on both sides of the gabion retaining wall, as well as to adjacent gabion units, via spirally wound steel wire. This spirally wound steel wire connection ensures that the load is evenly transferred from the gabion to the concrete pile, avoiding stress concentration and improving the structure's collaborative working ability.

[0009] Furthermore, each reinforcing cage includes multiple stirrups, with the two ends and the middle of each cage representing a first density zone and a second density zone, respectively. The stirrup density in the first density zone is greater than that in the second density zone. High-density stirrups are placed in the stress concentration zones at both ends of the reinforcing cage, significantly improving shear and bending strength and preventing cracking of the pile under alternating loads. The low-density zone in the middle optimizes material usage, reducing weight and cost.

[0010] Furthermore, each gabion unit is filled with stones with a compressive strength greater than or equal to MU30. This high-strength filling reduces the compressive deformation of the gabion unit.

[0011] Furthermore, each stone has a particle size of 150mm to 300mm. This particle size avoids the problem of stones that are too small being easily lost, and also prevents stones that are too large from affecting flexibility, allowing the structure to deform moderately under load without becoming unstable.

[0012] Furthermore, drainage ditches are installed on the foundation between the gabion retaining wall and the concrete support frame beams. These drainage ditches divert groundwater and rainwater, reducing water pressure erosion on the gabion retaining wall and increasing its service life. Attached Figure Description

[0014] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0015] refer to Figures 1-3 This embodiment provides a collaborative support structure for road collapse repair, which solves the problem that existing repair structures cannot simultaneously ensure support strength and stability. It includes two concrete piles 100, a gabion retaining wall 200, and a concrete support frame beam 300.

[0016] refer to Figure 1 and Figure 4 Two concrete piles 100 are symmetrically fixed in the foundation at the site of the road collapse. Each concrete pile 100 includes a reinforcing cage 11, which comprises multiple crisscrossing longitudinal and transverse reinforcing bars, as well as multiple stirrups 111 attached to the outer longitudinal bars. The two ends and the middle of each reinforcing cage 11 are respectively a first density zone and a second density zone. The density of the stirrups 111 in the first density zone is greater than that in the second density zone. High-density stirrups 111 are set in the stress concentration zone at both ends of the reinforcing cage 11, which significantly improves the shear and bending strength and prevents the pile from cracking under alternating loads; the low-density zone in the middle optimizes material use and reduces weight and cost.

[0017] The gabion retaining wall 200 is located between two concrete piles 100, and anchor members 21 are installed inside the gabion retaining wall 200, with both ends anchored to the middle of the two concrete piles 100 respectively. (Reference) Figure 1 and Figure 5 The two ends of the anchor bolt 21 pass through two concrete piles 100 and are threadedly connected to the anchor nuts 211. Rectangular washers 212 are provided at the connection points between the two anchor nuts 211 and the two concrete piles 100. The rectangular washers 212 effectively increase the stress-bearing area, reduce the concentrated pressure of the nuts on the surface of the concrete piles 100, prevent the concrete from crushing or cracking, and extend the service life of the connection point.

[0018] The concrete support frame beam 300 is set on one side of the gabion retaining wall 200. The concrete support frame beam 300 includes two inverted L-shaped columns 31. The bent ends of the two columns 31 are fixedly connected to two concrete piles 100 respectively. The tops of the two columns 31 are fixedly connected by a crossbeam 32. The bottom ends of the two columns 31 are fixed in the riverbed.

[0019] As a further solution in this embodiment, refer to Figure 3 The gabion retaining wall consists of over 200 gabion units. The stirrups 111 on the reinforcing cage 11 are fixedly connected to the gabion units located on both sides of the gabion retaining wall 200 via spirally wound steel wire. Adjacent gabion units are also fixedly connected with each other via spirally wound steel wire. The spirally wound steel wire can be galvanized steel wire with a diameter of 3mm. This spirally wound steel wire connection ensures that the load is evenly transferred from the gabion to the concrete piles 100, avoiding stress concentration and improving the structural cohesiveness.

[0020] In this implementation, each gabion unit is filled with stones with a compressive strength greater than or equal to MU30, and each stone has a particle size of 150mm to 300mm. The high-strength filler reduces the compressive deformation of the gabion unit. At the same time, the 150mm to 300mm particle size avoids the problem of excessively small stones easily escaping, and also prevents excessively large stones from affecting flexibility, allowing the structure to deform moderately under load without becoming unstable.

[0021] As a further embodiment, a drainage ditch 400 is provided on the foundation between the gabion retaining wall 200 and the concrete support frame beam 300. The drainage ditch 400 can divert groundwater and rainwater, reduce water pressure erosion on the gabion retaining wall 200, and increase the service life of the gabion retaining wall 200.

[0022] In summary, the beneficial effects of this solution are as follows: The concrete piles 100 provide robust rigid support, while the gabion retaining wall 200 adapts to minor foundation deformations and disperses load impacts through its flexibility. By combining the rigid concrete piles 100 with the flexible gabion retaining wall 200, a balance between high strength and high stability is achieved in road collapse repair. At the same time, the introduction of anchor bolts 21 and concrete support frame beams 300 connects the concrete piles 100, gabion retaining wall 200, and concrete support frame beams 300 into a whole, significantly improving the structure's resistance to overturning and sliding, and solving the problem that existing repair structures cannot simultaneously achieve both support strength and stability.

[0023] Although specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this solution. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this solution.
