Preparing method for shield tunnel forming duct piece damage repairing structure body
The invention discloses a preparing method for a shield tunnel forming duct piece damage repairing structure body. The preparing method includes the specific manufacturing steps that firstly, fragmentchiseling is conducted; secondly, fragmented surface cleaning is conducted; thirdly, expansion bolts are anchored in drill holes; fourthly, smearing of an interface agent is conducted; fifthly, a steel wire mesh piece is bound; sixthly, layered filling of repairing mortar is conducted; and seventhly, the surface is filled with color mixing mortar and is polished. By means of the preparing methodfor the shield tunnel forming duct piece damage repairing structure body, the manufacturing technology is easy and convenient, shield continuous construction is not affected, the interface adhesion performance is good after repairing, water retention and contraction prevention are effectively achieved, repairing structure bodies with different shapes and sizes can be manufactured according to ductpiece damage conditions, and the requirements for structural strength, durability and surface attractiveness are met.
本发明公开了一种盾构隧道成型管片破损修补结构体的制备方法，具体制作步骤为：1、碎块凿除；2、碎裂表面清理；3、钻孔锚固膨胀螺栓；4、涂界面剂；5、绑扎钢丝网片；6、分层填充修补砂浆；7、表面填充调色砂浆并打磨。本发明的一种盾构隧道成型管片破损修补结构体的制备方法，制作工艺简便，不影响盾构连续施工，修补后界面粘结性良好，能有效保水防收缩，可依管片破损情况制作不同形状和大小的修补结构体，满足结构强度、耐久性及表面美观要求。
