Description

Technical Field

[0001] This utility model relates to the technical field of road construction for important buildings and structures, and in particular to a road pile support structure for multiple high-voltage power towers. Background Technology

[0002] With the continuous development of urban construction, urban road construction increasingly involves the relocation of existing important structures such as power towers, buildings, bridges, tunnels, and culverts, which are either impossible or prohibitively expensive to relocate. During construction, a significant amount of roadbed slope excavation is also required. To ensure the safety of sensitive structures around the road, safe, feasible, economical, and easy-to-construct support technologies are needed for roadbed slopes. Commonly used methods include natural slope protection, anchor bolt (cable) support, retaining walls, and pile support. However, for sections near high-voltage power towers, natural slope protection or anchor bolt (cable) support cannot be used. Retaining wall construction also involves excavation, which has a significant adverse impact on nearby power towers. Conventional support methods require large-diameter or ultra-large-diameter cast-in-place piles to control deformation, resulting in high project costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a road pile support structure for multiple high-voltage power towers, which controls the deformation of the surrounding environment while taking into account economic rationality and convenient construction.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A road pile support structure adjacent to multiple high-voltage power towers includes a first retaining wall set on one side of the road adjacent to multiple high-voltage power towers and located at the road edge line between the tops of the road cutting slopes at both ends. A second retaining wall is set in the first retaining wall between two adjacent high-voltage power towers and on one side of the road cutting slope near both ends. A cap beam is set on the top of the first retaining wall and the second retaining wall. A tie beam is set between the second retaining wall between two adjacent high-voltage power towers and the first retaining wall located on both sides of the second retaining wall. The tie beam is also set between the second retaining wall on the side of the road cutting slope near both ends and the first retaining wall.

[0005] The beneficial effects of this utility model are as follows: The road pile support structure of this utility model for multiple high-voltage power towers is formed by setting a first retaining wall at the road edge line on one side of the multiple high-voltage power towers, and setting a second retaining wall inside the first retaining wall between two adjacent high-voltage power towers and on the top side of the road cutting slope near both ends, and forming a joint support system with tie beams. It is easy to operate, highly safe, economical and reasonable, and can ensure the safety of the power towers and the surrounding area.

[0006] Based on the above technical solution, the present invention can be further improved as follows:

[0007] Furthermore: the first retaining wall includes multiple first bored piles vertically fixed to the road edge line, and the multiple first bored piles are arranged side by side at intervals along the road edge line.

[0008] The beneficial effect of the above-mentioned further scheme is that by arranging multiple first-hole cast-in-place piles side by side at intervals along the road edge, a strong support effect can be achieved along the road edge, ensuring the overall structural stability.

[0009] Furthermore: The second retaining wall includes multiple second bored piles vertically fixed in the direction perpendicular to the road edge line, and the multiple second bored piles are arranged side by side at intervals along the direction perpendicular to the road edge line.

[0010] The beneficial effect of the above-mentioned further scheme is that by arranging multiple second bored piles side by side at intervals along the direction perpendicular to the road edge, a strong support effect can be achieved along the direction perpendicular to the road edge, ensuring the overall structural stability.

[0011] Further: Multiple first-hole cast-in-place piles are evenly spaced along the road edge, and multiple second-hole cast-in-place piles are evenly spaced along a direction perpendicular to the road edge.

[0012] The beneficial effect of the above-mentioned further scheme is that by setting the first and second bored piles at equal intervals, the overall stress can be more uniform, which is conducive to ensuring the stability of the overall structure.

[0013] Furthermore, the cap beams at the top of the first and second retaining walls are connected to form an integral structure.

[0014] The beneficial effect of the above-mentioned further solution is that by connecting the cap beams at the top of the first retaining wall and the second retaining wall into an integral structure, the forces along the road edge and perpendicular to the road edge can be combined, thereby improving the overall bearing capacity and ensuring the stability of the overall structure.

[0015] Furthermore, both the cap beam and the tie beam are reinforced concrete structures.

[0016] The advantages of the above-mentioned further solutions are: the reinforced concrete structure is easy to construct, has a short construction period, reasonable cost, and a mature construction plan.

[0017] Furthermore, stirrups are provided inside both the cap beam and the tie beam.

[0018] The beneficial effect of the above-mentioned further solution is that the use of the stirrups can further improve the stability of the connection between the two.

[0019] Further: A reinforced concrete facing wall is installed on the outside of the first retaining wall.

[0020] The beneficial effect of the above-mentioned further solution is that the reinforced concrete facing wall can protect the first support wall, thus making the entire support structure more stable.

[0021] Furthermore, the tops of the first and second retaining walls are respectively connected to the cap beam and the tie beam to form a whole bearing structure.

[0022] The beneficial effects of the above-mentioned further solution are: by connecting the tops of the first retaining wall and the second retaining wall to the capping beam and the tie beam respectively to form a whole bearing structure, it is beneficial to improve the overall utilization efficiency, shorten the construction cycle, reduce the cost, and ensure the stability of the support structure, thus ensuring the safety of the power tower and its surroundings.

It consists of a first retaining wall 1 installed at the road edge on one side of the multiple high-voltage power towers, and a second retaining wall 2 installed within the first retaining wall 1 between two adjacent high-voltage power towers and on one side of the road cutting slope near both ends. Together with tie beams 4, they form a joint support system. This system is easy to operate, highly safe, economical and reasonable, and can ensure the safety of the power towers and their surroundings.

[0031] In one or more embodiments of this utility model, the first retaining wall 1 includes a plurality of first bored piles vertically fixed to the road edge, and the plurality of first bored piles are arranged side by side at intervals along the road edge.

[0032] In one or more embodiments of this utility model, the second retaining wall 2 includes multiple second bored piles vertically fixed in a direction perpendicular to the road edge, with the multiple second bored piles arranged side-by-side at intervals along the direction perpendicular to the road edge. By arranging the multiple second bored piles side-by-side at intervals along the direction perpendicular to the road edge, a strong supporting effect can be achieved along the direction perpendicular to the road edge, ensuring the overall structural stability.

[0033] Optionally, in one or more embodiments of this utility model, a plurality of first bored piles are arranged at equal intervals along the road edge, and a plurality of second bored piles are arranged at equal intervals along a direction perpendicular to the road edge. By arranging the first and second bored piles at equal intervals, the overall stress distribution can be more uniform, which is beneficial to ensuring the stability of the overall structure.

[0034] In one or more embodiments of this utility model, the capping beams 3 at the top of the first retaining wall 1 and the second retaining wall 2 are connected to form an integral structure. By connecting the capping beams 3 at the top of the first retaining wall 1 and the second retaining wall 2 to form an integral structure, the load-bearing capacity can be improved by combining forces along the road edge direction and perpendicular to the road edge direction, thus ensuring the stability of the overall structure.
