本文针对铜官山饲矿选厂构筑物宏观破坏特征,阐述了在选厂持续生产条件下,采用预应力锚杆、锚轩桩和预预力锚杆井字形混凝土支承梁综合技术加固厂房内侧挡墙以及利用地层锚固力治理厂房地基构筑物损害的研究结果。工程实践表明:该项技术能有效防治构筑物破坏,确保选厂正常生产,取得明显加固效果。 This paper aims at the macroscopic damage characteristics of structures in Tongguanshan Oredressing Plant, and expounds that under the continuous production conditions of the plant, the integrated technology of prestressed anchors, anchor sill piles and pre-prestressed bolt-shaped concrete support beams is used to reinforce the inner block of the factory building. Walls and the use of strata anchoring force to deal with the damage to the building’s foundation structure. The engineering practice shows that this technology can effectively prevent and control the destruction of structures, ensure the normal production of the plant, and achieve significant reinforcement effects.
