Prestress-based roadbed settlement repairing device and method
The invention belongs to the technical field of roadbed settlement treatment, and particularly relates to a roadbed settlement repairing device and method based on prestress. The roadbed settlement repairing device comprises a precast pile transversely penetrating into a roadbed, one end of the precast pile extends out of the side edge of the roadbed, a prestressed tendon is connected into the precast pile, the other end of the prestressed tendon is connected with a prestressed tendon anchorage device, the prestressed tendon anchorage device is arranged on the side edge of the roadbed, and a plurality of grouting holes are formed in the precast pile. The roadbed settlement repairing method comprises the following steps that the number, the arrangement layer number and the penetration length of precast piles are determined according to the settlement state of a roadbed; transversely penetrating the precast pile into the settled roadbed from the side edge of the roadbed from bottom to top; the prestressed tendons are tensioned, and the prestressed tendons are anchored on the roadbed through anchoring of the prestressed tendon anchorage devices; grouting equipment is adopted to inject grout into the roadbed through the grouting holes. The invention provides a roadbed settlement repairing device and method combining the soil squeezing effect and grouting.
本发明属于路基沉降处理技术领域，特别涉及一种基于预应力的路基沉降修复装置及方法。本发明的路基沉降修复装置包括横向贯入路基内的预制桩，预制桩的一端从路基的侧边伸出，预制桩内连接有预应力筋，预应力筋的另一端连接有预应力筋锚具，预应力筋锚具设置于路基的侧边上，预制桩上设置有若干注浆孔。本发明的路基沉降修复方法包括以下步骤：根据路基沉降状态确定预制桩的数量、布置层数和贯入长度；由下而上将预制桩从路基侧边横向贯入沉降的路基中；张拉预应力筋，并通过预应力筋锚具锚固将预应力筋锚固在路基上；采用注浆设备通过注浆孔将浆液注入路基中。本发明提供了一种将挤土效应与注浆结合的路基沉降修复装置及方法。
