[0024] See also Figures 1 to 4 The pile foundation and retaining wall transverse reinforcement connection structure in one embodiment includes a pile foundation 10 and a retaining wall 20.

[0025] The pile foundation 10 is transversely pre-embedded with an embedded pipe 12, which transversely penetrates the opposite side walls of the pile foundation 10, that is, the pipe openings at both ends of the embedded pipe 12 are exposed outside the pile foundation 10, which is convenient for the subsequent insertion of the transverse steel bars 22. In one embodiment, the embedded pipe 12 is provided in multiple groups, and the multiple groups of embedded pipes 12 are arranged at intervals in the height direction in the pile foundation 10.

[0026] During specific implementation, after the pile foundation steel bars 221 are tied, the embedded pipes 12 are buried at a certain interval, and then the two ends of the embedded pipes 12 are fixed and closed, and then the concrete of the pile foundation 10 is poured to keep the embedded pipes 12 in a hollow state, to prevent concrete from entering the embedded pipes 12 and affecting the transverse steel bars 22 passing through the embedded pipes 12.

[0027] The retaining wall 20 has transverse steel bars 22, and the embedded pipe 12 is a through channel for the transverse steel bars 22. After the concrete of the pile foundation 10 solidifies, the transverse steel bars 22 are passed through the embedded pipe 12, and slurry is poured into the gap 122 between the transverse steel bars 22 and the inner wall of the embedded pipe 12. After the slurry solidifies, the concrete of the retaining wall 20 is poured to form a whole.

[0028] Among them, the pile foundation steel bars 221 and the retaining wall steel bars 222 are composed of a whole transverse steel bar 22, which avoids the problem of steel bar disconnection and discontinuity at the pile foundation 10 and ensures the integrity of the structure. The grouting material can connect the transverse steel bars 22 and the pile foundation 10.

[0029] In one embodiment, multiple groups of transverse steel bars 22 are provided, and the multiple groups of transverse steel bars 22 are evenly distributed in the height direction of the retaining wall 20. The multiple groups of transverse steel bars 22 are correspondingly inserted into multiple groups of embedded pipes 12 to resist external forces according to the force requirements of the retaining wall 20.

[0030] In one embodiment, the embedded pipe 12 is a corrugated pipe, and the corrugated form of the corrugated pipe can achieve a bite effect between the concrete of the pile foundation 10 and the grouting inside, thereby improving the interconnection performance. The diameter of the transverse reinforcement 22 is smaller than the inner diameter of the embedded pipe 12, which facilitates the penetration of the transverse reinforcement 22.

[0031] In one embodiment, the inner diameter of the embedded pipe 12 is a multiple of the diameter of the transverse steel bar 22, so that a certain gap 122 is maintained between the two, so that the grouting slurry reaches the necessary thickness, and ensures reliable bonding between the steel bar and the grouting slurry. Specifically, the inner diameter of the embedded pipe 12 can be 2-5 times the diameter of the transverse steel bar 22.

[0032] In one embodiment, the embedded pipe 12 is tilted relative to the horizontal plane so that the two ends of the embedded pipe 12 have a height difference, one end of the embedded pipe 12 is higher than the other end, and the two ends of the embedded pipe 12 have a height difference 124. After the transverse reinforcement 22 is installed, grout is poured into the embedded pipe 12 from a high position to a low position, so that the gap 122 between the embedded pipe 12 and the transverse reinforcement 22 is filled with grout, thereby enhancing the density of the grouting.

[0033] In the above-mentioned pile foundation and retaining wall transverse reinforcement connection structure, the embedded pipe 12 is buried during the construction of the pile foundation 10, and the transverse reinforcement 22 can be directly passed through the embedded pipe 12 during the subsequent construction of the retaining wall 20. Grouting is performed in the gap between the embedded pipe 12 and the transverse reinforcement 22 to complete the connection of the pile foundation 10 and the retaining wall 20 transverse reinforcement 22, avoiding the processes of embedding reinforcement drilling and reinforcement welding, and solving the problems of large workload and low efficiency of the existing method. The transverse reinforcement 22 is an integral structure, there is no discontinuity in the middle, the stress state is reliable, the structure is simple, the on-site implementation efficiency is high, and it can be widely promoted and applied.
