Method for reinforcing deformed wall body of barbican
The invention relates to a method for reinforcing a deformed wall body of a barbican. The method comprises root pile reinforcement and anchor rod grouting reinforcement. The treatment range of reinforcing the root piles is main stress layer foundation soil within 8.0-10.0 m below the terrace in areas on the east, west and south sides of urban terraces in charge of charge, the root piles are uniformly divided into a plurality of groups, each group comprises three piles, the included angle between the first pile and the ground in each group is 90 degrees, the included angle between the second pile and the ground is 75 degrees, and the included angle between the third pile and the ground is 60 degrees; according to anchor rod grouting reinforcement, grouting construction is carried out after anchor rods are placed at the cracking positions of the existing crack and the new and old rammed earth combination positions of the repaired crack. According to the method, root pile reinforcement and anchor rod grouting reinforcement are adopted, the technology is advanced, the design is scientific, disturbance to the existing building in the construction process is reduced as much as possible, secondary damage to the ancient city wall is effectively avoided, the repair quality is guaranteed, the repair problem is solved, and the later maintenance cost is reduced.
本发明为一种瓮城变形墙体加固方法，包括树根桩加固和锚杆注浆加固；树根桩加固的处理范围为瓮城城楼城台东、西、南侧区域内，地坪以下8.0‑10.0m以内主要受力层地基土，树根桩均分为若干组，每组包括三根桩，每组的第一根桩与地面夹角为90°、第二根桩与地面夹角为75°、第三根桩与地面夹角为60°；锚杆注浆加固是对既有裂缝瓮城墙体开裂处及修缮瓮城墙新旧夯填土结合处，通过放置锚杆后进行注浆施工。本发明方法采用了树根桩加固和锚杆注浆加固，技术先进、设计科学，尽量的减小了施工过程对既有建筑的扰动，又有效避免了对古城墙造成二次破坏，保证了修复质量，解决了修复难题，减少了后期维护费用。
