Problems solved by technology

In the current construction technology, due to the small distance between the inverted arch trestle and the bottom of the tunnel, the construction space is limited, the concrete of the track bed layer above the inverted arch cannot be vibrated effectively, and the strength of the track bed layer cannot be guaranteed. Lead to subsidence and damage to the track or road surface

Embodiment 1

[0028] The invention discloses a full-automatic high-frequency vibrating and leveling machine for an inverted arch of a tunnel. The vibrating and leveling machine includes a longitudinal running track 11 arranged at the lower end of an inverted arch trestle 10, and a longitudinal running track 11 arranged at the lower end of the longitudinal walking track 11. The moving walking frame 1 is equipped with rollers driven by motors at both ends of the walking frame 1. According to the construction sequence of first vibrating, then distributing and finally lifting and leveling, a vibrating device and a cloth leveling device are arranged under the walking frame 1 in sequence. Such as figure 1 , figure 2 as shown, figure 2 The direction indicated by the middle arrow is the direction in which the machine runs in the present invention during construction. The vibrating device can move laterally along the track on the walking frame 1, so as to ensure sufficient vibrating of the concr...

Embodiment 2

[0033] This embodiment is improved on the basis of Embodiment 1. In this embodiment, the cloth leveling device uses a leveling vibrating plate 8 driven by a high-frequency vibrator. The leveling vibrating plate 8 covers a large area, and the leveling vibrating plate 8 is attached to the formwork 15 to push the concrete material to achieve the leveling effect during the traveling process. At the same time, the surface stones are hit into the concrete by vibration to level the concrete. The template 15 attached to the leveling vibrating plate 8 can also be made into different templates according to the design shape of the road surface. For example, if the surface of the road mattress needs to have a certain angle on both sides of the middle level, the formwork attached to the leveling vibrating plate 8 is made into a corresponding shape. Specifically, the leveling vibrating plate 8 attached to the formwork 15 is as follows: Figure 7 shown. Such a construction can meet the cons...

Abstract

The invention discloses a full-automatic high-frequency vibrating leveling machine for a tunnel inverted arch and belongs to the technical field of road and bridge machinery. The vibrating leveling machine comprises a longitudinal travelling track arranged at the lower end of an inverted arch trestle, a travelling frame arranged at the lower end of the longitudinal travelling track and moving along the longitudinal travelling track, and a vibrating device and a material distributing and leveling device which are hung below the travelling track and are sequentially arranged in the front and the back, wherein the vibrating device and the material distributing and leveling device are connected with the travelling frame by a lift cylinder, and the vibrating device transversely moves along a track on the travelling frame. The full-automatic high-frequency vibrating leveling machine is mainly used for deep vibrating of a tunnel bed concrete cushion and mud extracting and leveling of the surface of the cushion, can carry out the vibrating leveling operation in a narrow space below the tunnel inverted arch, and is high in working efficiency, dense in vibrating, simple in construction process and good in mud extracting and leveling effects. According to the invention, the operation is simple and is executed by one people, the operation and stop of the machine can be controlled remotely, and the use is extremely convenient.

Description

technical field [0001] The invention relates to a vibrating and leveling machine, in particular to a full-automatic high-frequency vibrating and leveling machine for a tunnel inverted arch, belonging to the technical field of road and bridge machinery. Background technique [0002] During tunnel construction, an inverted arch structure of concrete material is set at the bottom of the tunnel, which is often called an inverted arch. The inverted arch can improve the stress conditions of the upper support structure of the tunnel, effectively resist the reaction force from the bottom layer of the tunnel, and increase the stability of the structure. In the current construction technology, due to the small distance between the inverted arch trestle and the bottom of the tunnel, the construction space is limited, the concrete of the track bed layer above the inverted arch cannot be vibrated effectively, and the strength of the track bed layer cannot be guaranteed. Lead to the phen...
