Concrete support static crushing method with existing crack as guide
The invention discloses a concrete support static crushing method with an existing crack as a guide, and relates to the technical field of concrete support crushing. The problems that an existing static crushing method is large in blindness and uncontrollable in crushing result are solved. The method comprises the following steps that the distribution condition of internal cracks of a concrete support is determined, parameterized recognition is conducted on the distribution condition, the internal cracks are divided into a plurality of crushed areas according to the lengths and the widths of the internal cracks, the vertical distances from the two ends of the internal cracks to the outer surfaces of the two sides of the concrete support in the length direction and the distance between every two adjacent internal cracks, an internal crack with the possibility of penetrating through the section of the concrete support is divided into a crushed area, holes are drilled in the two sides, in the length direction of the concrete support, of each crushed area correspondingly, the drilled holes in the two sides communicate with the ends of the internal crack of the crushed area, a static crushing agent is injected into the drilled holes, and after the effect of the static crushing agent is completely released, the steps are repeated until the internal cracks penetrate through the whole concrete support section.
本发明的以既有裂缝为导向的混凝土支撑静力破碎方法，涉及混凝土支撑破碎技术领域。针对现有静力破碎方法存在盲目性较大，破碎结果不可控的问题。步骤如下：确定混凝土支撑内部裂缝的分布情况并对其进行参数化识别，根据内部裂缝的长度、宽度、内部裂缝两端至混凝土支撑长度方向两侧外表面的垂直距离，及相邻两个内部裂缝之间的距离，将内部裂缝划分为若干破碎区域，将具有贯通混凝土支撑断面可能性的内部裂缝划分为一个破碎区域，在各破碎区域沿混凝土支撑长度方向的两侧分别钻孔，且两侧钻孔与该破碎区域的内部裂缝的端部连通，在钻孔内注入静力破碎剂，待静力破碎剂效力释放完成后，反复上述步骤，直至内部裂缝贯穿整个混凝土支撑断面。
