Pre-reinforcing device for repairing power transmission terminal tower pile foundation and construction method of pre-reinforcing device
The invention relates to the technical field of pile foundation reinforcement and particularly relates to a pre-reinforcement device for repairing a power transmission terminal tower pile foundation and a construction method of the pre-reinforcement device. The pre-reinforcing device comprises a bamboo joint pipe pile, a bearing platform supporting structure and grouting equipment, wherein the bamboo joint pipe pile comprises a pile cap, a pile head, a pile body and a pile tip, grouting holes are formed in the connecting positions of the pile head and the pile body, the strength of the connecting positions can be enhanced, and the anti-pulling capacity is improved; rib grooves are formed in the pile tip, the ground breaking effect can be enhanced, slurry discharging is facilitated, and the pile foundation bearing capacity is improved; the bearing platform supporting structure comprises a buttress, a distribution beam, a meter type jack and a cushion block, damage to the bearing platform can be reduced, and recycling is facilitated. According to the pre-reinforcing device and the construction method thereof, the bearing capacity of the foundation before drilling and grouting can be improved, disturbance of follow-up drilling and grouting reinforcement on the power transmission terminal tower is effectively reduced, and safety and stability of power transmission terminal tower pile foundation repairing operation are guaranteed.
本发明涉及桩基加固技术领域，具体涉及一种用于输电终端杆塔桩基修复的预加固装置及其施工方法。该预加固装置包括竹节管桩、承台支撑结构和注浆设备。竹节管桩包括桩帽、桩头、桩身、桩尖，在桩头和桩身连接处均设置注浆孔，可以增强连接处强度，提高抗拔能力；桩尖设置凸棱槽，可增强破土效果，利于排浆，提高桩基承载能力。承台支撑结构包括支墩、分配梁、表式千斤顶、垫块，可以减小对承台的损坏，且便于回收利用。本发明提供的预加固装置及其施工方法可以提高钻孔注浆前地基的承载能力，有效减小后续钻孔注浆加固对输电终端杆塔的扰动，保证输电终端杆塔桩基修复作业的安全稳定性。
