Construction method of gap and groove girder prefabrication site tire foundation reinforcing structure
The invention relates to the technical field of beam field construction, and discloses a construction method of a gap and groove girder prefabricating field tire foundation reinforcing structure, which comprises the following steps: step S1, carrying out integral preparation before construction, carrying out survey lofting on the position of a tire according to a construction drawing, determining the position detected by a geological radar, and carrying out detection; s2, foundation treatment is conducted, specifically, when collapse occurs in the soluble gap and soluble groove development water-rich easy-to-wash sandy soil area, foundation treatment is conducted according to the situation that whether a continuous sinking trend exists in the non-improvement continuous sinking collapse position or not and the situation that a soluble cavity is exposed; according to the method, the ground tire foundation is treated firstly, then the full-length reinforced concrete strip-shaped foundation is adopted, the full-length reinforced concrete sleeper beams are arranged at the two ends of the foundation, and the steel bar meshes are fully laid on the top face of the foundation, so that the ground tire foundation forms reinforced concrete grid beams which are high in integrity and have certain rigidity; and damage to the precast beam in production caused by ground tire foundation sinking or cracking due to local collapse and settlement of the foundation is prevented.
本发明涉及梁场建设施工技术领域，且公开了一种溶隙溶槽的大梁预制场地胎基础加固结构的施工方法，包括以下步骤：步骤S1、进行施工前的整体准备，根据施工图纸对地胎位置进行测量放样，确定地质雷达探测的位置并进行探测；步骤S2、地基处理，当溶隙溶槽发育富水易冲刷砂性土地区发生塌陷，根据无改善继续下沉塌陷处有无继续下沉趋势以及溶腔揭露的情况进行地基处理；本发明先进行地胎地基处理，再采用通长钢筋混凝土条形基础，基础两端布设通长钢筋混凝土枕梁，基础顶面满铺钢筋网片，使地胎基础形成整体性强、具有一定刚度的钢筋混凝土方格梁上，防止因地基局部塌陷沉降导致地胎基础下沉或开裂而造成对生产中的预制梁的破坏。
