Assembly type reinforced concrete foundation pit supporting system convenient to disassemble and disassembling method
The invention relates to the field of constructional engineering, and discloses a fabricated reinforced concrete foundation pit supporting system convenient to dismount and a dismounting method. According to the system, foundation pit supporting beam sections and foundation pit supporting splayed beams are adopted as fabricated components, supporting structures in a foundation pit are arranged in an orthogonal diagonal bracing mode, the beam sections are spliced through joint bars, a plurality of supporting steel latticed columns are arranged in the middle of the supporting system, and jacks are arranged between supporting beams and top beams or waist beams. A rope threading hole for cutting is formed in the top beam or the waist beam; according to the dismantling method of the fabricated reinforced concrete foundation pit supporting system convenient to dismantle, main tools such as a crane and a rope saw are used, and the detailed working procedure of dismantling from the bottommost layer to the upper layer step by step is conducted from the bottommost layer to the upper layer; compared with a traditional blasting demolition means, the method is high in demolition speed, low in noise pollution and dust pollution and low in demolition cost, the demolition beam sections, jacks and the like which are demolited can be recycled and reused, and the remarkable cost and environmental protection advantages are achieved.
本发明涉及建筑工程领域，公开了便于拆除的装配式钢筋混凝土基坑支撑体系及拆除方法；该体系采用基坑支撑梁段和基坑支撑八字梁作为装配式构件，基坑内的支撑结构采用正交对撑的形式布置，梁段彼此通过插筋拼接，支撑系统中间设置若干支撑钢格构柱，支撑梁与冠梁或腰梁之间设置有千斤顶，冠梁或腰梁上设置了切割用穿绳孔；本发明给出了该便于拆除的装配式钢筋混凝土基坑支撑体系的拆除方法，使用吊车和绳锯等主要工具，从最底层支撑开始，逐步往上层拆卸的详细工序；相对于传统爆破拆除手段，该方法不仅拆除速度快，噪音污染和粉尘污染少，拆除成本低，拆下的梁段、千斤顶等还可以回收重复使用，具备显著的成本和环保优势。
