High-pressure jet expanded-head pre-stressed anchor cable construction process
The invention provides a high-pressure jet expanded-head pre-stressed anchor cable construction process. The high-pressure jet expanded-head pre-stressed anchor cable construction technology comprises the following steps that S1, anchor cable bodies are manufactured, specifically, (1) the anchor cable bodies should be straightly arranged, isolation frames are arranged in the axis direction of the cable bodies every 1-1.5 m, and grouting pipes and exhaust pipes should be firmly bound with the cable bodies; (2) positioning supports are arranged in the axis direction of the cable body every 2-3 m and firmly bound through iron wires, and the protective layer of the cable body should not be smaller than 20 mm; by means of the construction technology of the structure, the high-pressure jet expanded-head pre-stressed anchor cable construction technology has the advantages of being high in pulling resistance, small in displacement and good in reliability, meanwhile, a drilling machine is used, the problem that a water injection pipe and a grouting pipe need to be continuously replaced by a conventional drilling machine is solved, use is convenient, time and labor are saved, and the construction efficiency is improved. And the on-site construction speed can be accelerated.
本发明提供一种高压喷射扩大头预应力锚索施工工艺。所述高压喷射扩大头预应力锚索施工工艺包括以下步骤：S1.锚索体制作：(1).锚索体应平直排列，沿索体轴线方向每隔1‑1.5m设置一个隔离架，注浆管和排气管应和索体绑扎牢固；(2).沿索体轴线方向每隔2‑3m设置一个定位支架，用铁丝绑扎牢固,索体的保护层不应小于20mm。本发明提供的高压喷射扩大头预应力锚索施工工艺通过上述结构的施工工艺，使其具有单根抗拔力高、位移较小、可靠性好的优点，同时使用钻孔机械，解决了常规钻孔机械需要不断更换注水管和注浆管的问题，使用方便且省时省力，进而可以加快现场施工速度的优点。
