In the actual construction process, first of all, the cushion stone 4 needs to be poured at the predetermined design position of the pier, and after the strength of the cushion stone 4 is qualified, the cross center control line is measured and placed in place by the surveyor, and the mark is made with black ink. Then, the bridge steel support 5 to be installed is hoisted to the top of the cushion stone 4. Then, the tool is installed in place, so that the cushion stone 4 and the bridge steel support 5 are located inside the load-bearing support 1 of the tool. It is worth mentioning that in order to optimize the structure of the tool and improve its practicability, the number of multi-directional sliding rails 2 in the design is reduced to two groups, and there are two adjustable screw rod hangers 3 on each multi-directional sliding rail 2. At this time, the installer needs to slide the adjustable screw rod hangers 3 along the multi-directional sliding rails 2 to the four sides of the bridge steel support 5, respectively, and then pass through the bridge steel support 5, and then complete the fixing work, so that the bridge steel support 5 is in a suspended state. Then, according to the control line measured in advance on the top surface of the cushion stone 4, the installer can use the L-shaped ruler as an auxiliary tool to adjust the position of the multi-directional sliding rail 2, so as to adjust the position of the bridge steel support 5, so as to ensure that the position of the bridge steel support 5 can meet the design requirements. After the planar position adjustment of the bridge steel support 5 is completed, the installer needs to cooperate with the surveyor to adjust the height adjustment assembly 6 on the upper part of the four adjustable screw rod hangers 3, so as to adjust the elevation and levelness of the bridge steel support 5. When the planar position and elevation of the bridge steel support 5 meet the requirements, and after being accepted by the site supervision engineer, the support grouting process can be carried out. After the strength of the support grouting material reaches the design requirement, the adjustable screw rod hangers 3 can be removed, and finally the tool is removed. The rest of the design position support construction process is the same. Compared with the traditional installation process, the use of the tool can effectively improve the installation efficiency of the support, ensure high installation precision, and is simple to operate and has a simple structure, which is convenient for processing and popularization. In addition, the application of the tool can also effectively reduce the investment of machinery and labor, and can be reused, further reducing the construction cost, and providing a strong guarantee for efficient construction and quality control in the field of bridge construction.
