Bearing platform expanding and reinforcing structure and reinforcing method
The invention relates to a bearing platform expanding and reinforcing structure and a reinforcing method. The reinforcing structure comprises a plurality of anchor rod rings, a plurality of grouting pipes and a reinforced concrete block, wherein the anchor rod rings are vertically inserted in the periphery of the bearing platform; the grouting pipes are fixed to the outer sides of the top ends of the anchor rod rings correspondingly and used for grouting the peripheries of the anchor rod rings; the reinforced concrete block is poured on the bearing platform and internally connected with a pier column; the grouting pipe located between the two adjacent anchor rod rings is fixed to the adjacent edge positions of the two adjacent anchor rod rings, the top elevation of the anchor rod rings is flush with the top elevation of the bearing platform, and the bottom elevation of the anchor rod rings is lower than the bottom elevation of the bearing platform. The technical problems that in the prior art, a bearing platform expanding method of a modified structure is complex, and safety influence is easily generated on a peripheral structure by excavation of the periphery of the bearing platform are solved. The existing bearing platform, the newly-added mortar anchor rods and the newly-added reinforced concrete form a system, the aim of reinforcing the existing bearing platform is achieved, concentrated loads borne by the original bearing platform part are reduced, and then the purposes of increasing the section and improving the bearing capacity are achieved.
本发明涉及一种承台扩大加固结构及加固方法，加固结构包括用于竖直插设于承台周围的多圈锚杆圈、分别固定于多圈该锚杆圈顶端外侧并用于向对应该锚杆圈外周注浆的多圈注浆管、以及浇筑在该承台上并内接墩柱且外沿覆盖至最外圈该锚杆圈顶端的钢筋混凝土块，位于相邻两圈该锚杆圈之间的该注浆管固定于相邻两圈该锚杆圈的相邻边缘位置，该锚杆圈的顶标高与该承台顶标高齐平，该锚杆圈的底标高低于该承台的底标高。本发明解决了现有技术中的改造结构的承台扩大方法复杂且承台周边开挖易对外周结构产生安全影响技术问题。本发明通过将既有承台、新增砂浆锚杆、新增钢筋混凝土形成一个体系，达到对既有承台加固的目的，减少原有承台部位承受的集中荷载，进而达到增大截面，提高承载力的目的。
