Problems solved by technology

[0002] With the continuous construction of long tunnels and the continuous improvement of tunnel construction standards, the construction quality of tunnel inverted arches has become the focus of construction. In the past construction, most of the inverted arch concrete was vibrated manually and the surface was closed. The labor intensity of the operators was high. , small working space under the trestle bridge, poor working environment, high risk, and large errors in the elevation of the later closing surface, etc. At the same time, the construction of the working platform in advance caused an increase in construction costs

Abstract

The invention discloses a construction technology of inverted arch concrete by a mechanical automatic vibrating device. The method comprises the following steps that 1, safety protection meshes are arranged on the outer sides of trusses on both sides of a trestle so as to prevent soil blocks or gravel from falling to cause injury to construction operation personnel below; and a dustproof device isinstalled at a construction site to reduce the pollution to the surrounding environment caused by oil and waste produced during the construction process. Manual work of 4 people is saved during construction of each inverted arch (24m), 6 hours of construction time are saved, and 3,328 yuan is saved in the construction cost; later high cost rework caused by the high heights of the filling surfacesof the inverted arches in the whole ballast-bed construction process is reduced; and at the same time, the labor intensity of construction operation workers is effectively reduced, the working environment of the construction operation workers is improved, the construction safety is ensured, and shortcomings of a traditional construction method are effectively compensated.

Description

technical field [0001] The invention relates to the technical field of concrete construction, in particular to a mechanical automatic vibrating equipment for inverted arch concrete construction technology. Background technique [0002] With the continuous construction of long tunnels and the continuous improvement of tunnel construction standards, the construction quality of tunnel inverted arches has become the focus of construction. In the past construction, most of the inverted arch concrete was vibrated manually and the surface was closed. The labor intensity of the operators was high. , Small working space under the trestle bridge, poor working environment, high risk, and large errors in the elevation of the later closing surface, etc. At the same time, the construction of the working platform in advance will increase the construction cost. [0003] Therefore, it is necessary to invent a kind of mechanical automatic vibrating equipment to carry out inverted arch concret...
