Construction method of water-damage-resistant reinforced protection structure of existing bridge bearing platform
The invention relates to a construction method of a water-damage-resistant reinforced protection structure of an existing bridge bearing platform. The construction method comprises the following steps: (1) constructing a roughening structure on the side face of the existing bridge bearing platform; 2) mounting and fixing a prefabricated embedded stiffening core beam on the side surface of the existing bearing platform through a pull rod and a fastening nut; (3) installing a radial auxiliary drawing die system on the pier stud, and installing an auxiliary die supporting frame on the outer sideof the existing bearing platform; (4) installing a formwork of the outer wrapped concrete structure; (5) pouring concrete between the existing bearing platform and the formwork, and constructing an outer wrapped concrete structure; 6) constructing a rubble enclosure structure; and (7) arranging an integral steel wire mesh gabion protection foot on the outer side of the bottom end of the precast slab pile. The method has the beneficial effects that the embedded type stiffening core beam is of a prefabricated structure, and the strength of the outer wrapped concrete structure can be effectivelyimproved, so the reinforcing effect of an existing bearing platform is improved; and a guide type chiseling cutting device conducts rotary cutting along the existing pier stud, and a chiseling structure can be rapidly cut out on the surface of the existing pier stud.
本发明涉及现役桥梁承台抗水毁加固防护结构施工方法，包括步骤：1)现役承台侧面的凿毛结构施工；2)在现役承台的侧面通过拉杆及紧固螺母，安装固定预制的埋入式劲芯梁；3)在墩柱上安装放射状辅助拉模体系，在现役承台的外侧安装辅助支模架；4)安装外包混凝土结构的模板；5)在现役承台与模板之间灌注混凝土，进行外包混凝土结构的施工；6)毛石围护结构施工；7)在预制板桩底端的外侧设置整体式钢丝网石笼护脚。本发明的有益效果是：埋入式劲芯梁采用预制结构，能够有效提升外包混凝土结构的强度，从而提升现役承台的加固效果；导向式凿毛切割装置沿着现役墩柱旋转切割，可快速地在现役墩柱的表面切割出凿毛结构。
