Verticality control of the bridge thin-wall pier by using turnover formwork

Combined with the concrete engineering example,the author introduces the construction technology,the construction process and the construction points of the turnover formwork,puts forward the control measures of the verticality of the bridge thin-wall pier by using the turnover formwork construction,to perfect the construction technology of the turnover formwork,and promote the application of the turnover formwork in the construction of the bridge thin-wall pier.
