Damping protection device and method for existing structure in percussion drill construction
The invention discloses an existing structure damping protection device and method in percussion drill construction, and the method comprises the steps: determining the plane position of a damping ditch according to the position of an existing structure; a ditch body is constructed at the design position of the damping ditch, then lightweight concrete is poured into the ditch body, and the lightweight concrete lifts a baffle to discharge slurry in the damping ditch; a foundation pit of a shock pad layer is excavated, a profile steel support is installed in the foundation pit, then sand bags and filling materials are alternately backfilled, and percussion drill equipment is installed on the profile steel support. According to the damping protection device and method for the existing structure in percussion drill construction, the damping grooves are used for weakening damage to the structure caused by vibration shock waves generated by the percussion drill bit, the damping cushion layer is used for reducing vibration of the percussion drill body to the ground when the winch lifts the drill bit and brakes, and the purpose that the structure is protected under the environment close to a sensitive structure is achieved. The percussion drill is safely, environment-friendly and economically used for operation, noise is reduced, and the damage influence of the percussion drill on structures is reduced.
本发明公开了一种冲击钻施工中既有构筑物减震保护装置及方法，根据既有构筑物的位置，确定减震沟的平面位置；在减震沟的设计位置施工出沟体，然后向沟体内浇筑轻质混凝土，轻质混凝土抬举挡板将减震沟内的泥浆排出；开挖减震垫层的基坑，在基坑内安装型钢支架，然后交替回填沙袋和填充材料，将冲击钻设备安装于型钢支架上。上述冲击钻施工中既有构筑物减震保护装置及方法，利用减震沟弱化冲击钻钻头产生震动冲击波对构筑物产生的破坏，利用减震垫层减轻卷扬机提起钻头在刹车时冲击钻本体对地面的震动，实现了在临近敏感构筑物的环境下，安全、环保、经济的使用冲击钻作业，减少了噪音降低了冲击钻对构筑物的破坏影响。
