Problems solved by technology

[0002] The displacement control of the traditional tunnel construction formwork arch trolley mechanism when it is walking or fixed is a technical difficulty in tunnel construction. For the dynamic change error generated after the track installation, the fixed error of the walking wheel groove, and the balance of the arch trolley mechanism error, it is difficult to realize process control and control when the arch trolley is walking or fixed
In this process, if the displacement of the arch trolley is not controlled in time, it will result in time-consuming and laborious calibration during the construction process, low work efficiency, and finally it will be difficult to guarantee the construction quality of the arch forming

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] A method for positioning a formwork arch trolley in tunnel construction by a ruler includes the following steps:

[0019] 1) Determine that the traveling mechanism that needs to be positioned by the ruler is the tunnel construction formwork arch trolley;

[0020] 2) In the forward direction of the formwork arch trolley, that is, in the forward direction of the excavation construction tunnel, according to the technological requirements, parallel and symmetrical to the center line of the excavation construction tunnel, determine the parallel position line that needs to be installed with the ruler, and lay out several on the determined position line. Steel piles, use angle steel to fix the steel piles on each side to form a positioning guide for the tunnel construction formwork arch trolley; install calibration contact points on t...

Abstract

The invention discloses a tunnel construction template arch centering trolley guiding rule positioning method, which comprises the following steps: in the advancing direction of a tunnel under tunneling construction, according to the process requirements, parallel position lines needing guiding rules to be installed are symmetrically determined by being parallel to the midline of the tunnel under the tunneling construction; a plurality of steel piles are distributed on the position lines, and are fixedly connected by adopting angle iron, thus forming tunnel construction template arch centering trolley positioning guiding rules; installation calibration contacts are arranged on the left and right sides of a template arch centering trolley; by virtue of the gap between the calibration contacts and the positioning guiding rules, the position of the template arch centering trolley in the tunnel under the tunneling construction is determined. According to the positioning method disclosed by the invention, for dynamic change errors generated after track installation, fixing errors of traveling wheel grooves and balance errors generated by an arch centering trolley mechanism, when the arch centering trolley travels or is fixed, process control and master control can be favorably realized; the travelling dynamic state and positioning in fixation of the arch centering trolley are easily observed and controlled, thus the work efficiency can be improved, and the measure cost is low.

Description

technical field [0001] The invention relates to a method for positioning a tunnel construction formwork arch trolley by a ruler, in particular to a method for positioning a tunnel construction formwork arch trolley by a ruler. Background technique [0002] The displacement control of the traditional tunnel construction formwork arch trolley mechanism when it is walking or fixed is a technical difficulty in tunnel construction. For the dynamic change error generated after the track installation, the fixed error of the walking wheel groove, and the balance of the arch trolley mechanism Error, when the arch trolley is walking or fixed, it is not easy to realize process control and control. In this process, if the displacement of the arch trolley is not controlled in time, it will result in time-consuming and laborious calibration during the construction process, low work efficiency, and finally it will be difficult to guarantee the construction quality of the arch forming.
