Arch bridge construction tie rod regulating system

Abstract

The invention provides an arch bridge construction tie rod regulating system. The system comprises a hydraulic system, a displacement sensor and a console; the hydraulic system comprises a hydraulic terminal and a hydraulic pump station, and the hydraulic pump station supplies hydraulic oil for the hydraulic terminal so as to regulate the hydraulic pressure output by the hydraulic terminal; the hydraulic system is used for applying acting force to an arch rib; the displacement sensor is used for measuring the end displacement of the arch rib; the console is connected with the hydraulic pump station and the displacement sensor through a data line; the hydraulic terminal is used for applying acting force to an end of the arch rib, the displacement sensor is used for measuring the displacement of the end of the arch rib and transmitting the result of measurement to the console, and the console is used for controlling the quantity of the hydraulic oil supplied by the hydraulic pump station for the hydraulic terminal according to the data of the displacement sensor.

Description

technical field [0001] The invention relates to an adjustment system for tie rods in construction of an arch bridge, in particular to an adjustment system for tie rods in the construction of an arch bridge with an arch first and then a girder type. Background technique [0002] In recent years, the under-connected tied arch bridge has been widely used in the construction of urban roads and bridges because of its advantages such as reasonable structural stress, economical cost, beautiful bridge shape, and good coordination with the surrounding environment. [0003] Such as figure 1 As shown, the under-through tied arch bridge 100 includes arch ribs 101 , piers 102 and tie rods 103 . Generally, it is a single span, but there are also two or three continuous spans. The tied arch bridge offsets the horizontal thrust generated by the arch rib 101 through the prestress applied in the tie rod 103, so that the pier 102 does not need to bear the horizontal thrust, and effectively s...

AI Technical Summary

Problems solved by technology

Tied arch bridges are mostly constructed by in-situ pouring. According to the division of construction procedures, there are mainly the beam-first-arch method and the arch-beam-first method. In the construction process of the arch-beam method, horizontal displacements occur at both ends of the arch rib 101 during the construction of the tie beam. As a result, the arch rib 101 is deformed, which affects the construction quality
