Description

Visual observation structure of two lining platform trucks in tunnel

Technical Field

The utility model belongs to an auxiliary observation device for concrete pouring of a two-lining trolley, and particularly relates to a visual observation structure for a tunnel two-lining trolley.

Background

At present, the panels of the two-lining trolley widely applied to the market are all made of steel plates, working windows are arranged on the panels at certain intervals, although a certain observation effect is achieved, most of the casting conditions of the two-lining concrete cannot be observed, the casting and vibration of the two-lining concrete cannot be guided in time, the casting and vibration of the two-lining concrete have to depend on construction experience, artificial influence factors are large, and pitted surfaces or incompact local parts of the two-lining concrete after form removal due to insufficient distribution or vibration, so that the solid quality of the two-lining concrete is influenced. In order to overcome the construction defects of the current two-lining pouring, open a blind box for pouring the two-lining concrete and realize the visual operation of the two-lining concrete pouring, a visual device with simple structure and stable working performance is needed to be invented to guide the two-lining pouring and vibrating so as to further improve the construction quality of the two-lining concrete.

Disclosure of Invention

The utility model aims to solve the technical problem that most of secondary lining concrete pouring conditions cannot be observed through a working window on a panel of the existing secondary lining trolley, and provides a visual observation structure of a tunnel secondary lining trolley.

The technical means for solving the technical problems of the utility model is as follows: a visual observation structure of a tunnel secondary lining trolley comprises a plurality of visual observation windows arranged on a panel of the secondary lining trolley; the visual observation bed comprises a window frame, wherein double-layer laminated toughened glass is arranged on the window frame, and a sealing rubber ring is arranged between the window frame and the double-layer laminated toughened glass and provides buffering and sealing effects for the double-layer laminated toughened glass; the window frame is a round-corner rectangular window frame. The window frame is made of angle steel, and the angle steel is welded with the panel; the outer side of the window frame and the panel are polished to be smooth. The panel is a rigid plate at the outer edge of the two-lining trolley and provides an inner membrane for casting of two-lining concrete. The outer side of the double-layer laminated toughened glass is flush with the panel. The visual observation windows are arranged on the panel at equal intervals.

The utility model has the beneficial effects that: the visual observation window can realize the overall process observation of the two-lining concrete construction, and can pertinently guide the operator to adjust the two-lining concrete cloth and the vibrating window in time, thereby having remarkable effect on improving the quality of the two-lining concrete construction operation.

Detailed Description

A detailed description will be given of a visual observation structure of a tunnel two-lining trolley according to the present invention with reference to fig. 1, 2 and 3.

A visual observation structure of a tunnel secondary lining trolley comprises a plurality of visual observation windows 2 which are arranged on a panel 1 of the secondary lining trolley, wherein the visual observation windows 2 are arranged on the panel 1 at equal intervals, and the arrangement form is that the annular interval is 2m, and the longitudinal interval is 1.5 m; the number of the visual observation windows 2 is equal to that of the working windows 6 on the table top, the visual observation windows 2 correspond to the working windows 6 one by one and are positioned below the working windows 6, and the working windows 6 are windows arranged on the trolley panel 1 at a certain distance and provide working windows 6 for the distribution and vibration of the secondary lining concrete; the panel 1 is a rigid plate at the outer edge of the secondary lining trolley and provides an inner membrane for secondary lining concrete pouring; as shown in fig. 3, the visual observation bed comprises a window frame 3, a double-layer laminated toughened glass 4 is mounted on the window frame 3, a sealing rubber ring 5 is arranged between the window frame 3 and the double-layer laminated toughened glass 4, and the sealing rubber ring 5 provides buffering and sealing effects for the double-layer laminated toughened glass 4; the window frame 3 is fillet rectangle window frame 3, and window frame 3 is made by the angle steel, and the angle steel welds with panel 1 mutually, and 3 outsides of window frame are polished smoothly with panel 1, and visual observation window 2's size is 1.0 m 0.8m, and chamfer R is 0.4m, and the outside of double-deck doubling toughened glass 4 flushes with panel 1.

During the concrete use, during two lining concrete pouring, operation personnel accessible visual observation window 2 clearly observes two lining concrete along vertical, circumferential cloth and the condition of vibrating, in time guides operation personnel to change cloth window and the window of vibrating, ensures that two lining concrete construction quality is up to standard.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
