Static cutting construction method for existing concrete structure without support frame
The invention provides a static cutting construction method for an existing concrete structure without a supporting frame. The static cutting construction method comprises the steps of construction preparation, surveying and setting out, water drill drilling, wire saw machine and guide wheel fixing, wire saw installing, pre-hoisting, cutting and removing. In the pre-lifting step, a lifting appliance is fixed to the to-be-cut block through a lifting hole, upward pulling force is applied to the to-be-cut block through the lifting appliance, and the pulling force is 1-1.2 times of the weight of the to-be-cut block. Non-support cutting of the concrete structure is achieved, during cutting, a supporting structure does not need to be arranged for supporting the to-be-cut block, the workload of erecting a supporting body is reduced, and the construction process is more efficient and safer.
本申请提供一种无支撑架既有混凝土结构静力切割施工方法，包括施工准备、测量放线、水钻钻孔、固定绳锯机及导向轮、安装绳锯、预吊及切割并移除的步骤。预吊步骤中包括将吊具通过吊装孔与待切割块固定，并通过吊具对待切割块施加向上的拉力，且拉力的大小为待切割块重量的1‑1.2倍。本申请实现混凝土结构的无支撑切割，切割时，无需设置支撑结构对待切割块进行支撑，减少了架设支撑体的工作量，使得施工过程更加高效且安全。
