Problems solved by technology

The problem is that honeycomb and pitting pouring defects are easily formed on the side wall of the tunnel due to insufficient vibration
The problem is that this solution occupies the position of the vibrating window, so that the vibrating device extending into the cavity of the second lining needs to cover a larger area, and it is difficult to install an attached vibrator at the position of the T-shaped template. Therefore, there is a problem of insufficient vibration

Embodiment 1

[0044] like figure 1 , 2 Among them, a tunnel lining construction trolley includes a trolley frame 7, the top of the trolley frame 7 is provided with a top mold 1, and both sides of the trolley frame 7 are provided with side molds 9;

[0045] A plurality of over-pouring compensating devices 5 are arranged on the inner side of the top mold 1, and a telescopic telescopic disk 51 is arranged on the over-pouring compensation device 5. In a telescopic position, the outer surface of the telescopic disk 51 is flush with the outer wall of the top mold 1 , the telescopic disc 51 is used to form a super-pouring cavity during pouring, and the telescopic disc 51 stretches out after pouring to make the poured concrete compact or beautiful;

[0046] A displacement sensor 13 for detecting the position of the telescopic disk 51 is also provided. In this example, the magnetostrictive displacement sensor 13 is preferably used. The displacement sensor 13 is used to enable the telescopic disk ...

Embodiment 2

[0064] like figure 2 , 4 In ~6, a vibrating device for a tunnel lining construction trolley, the over-pouring compensation device 5 is provided with a telescopic telescopic disk 51, and in a telescopic position, the outer surface of the telescopic disk 51 is flush with the outer wall of the formwork , the overcasting compensation device 5 is installed at the position of the vibrating window 100, the vibrating window 100 is provided with a vertical edge, and the side wall of the telescopic disk 51 is sealed and slidingly connected with the vertical edge;

[0065] The telescopic disc 51 is connected with the piston rod 52, the piston rod 52 is located in the cylinder body 54, and the cylinder body 54 is fixedly connected with the inner wall of the top die 1 or the side die 9;

[0066] A displacement sensor 13 for detecting the position of the telescopic disk 51 is also provided.

[0067] In a preferred solution, the piston rod 52 is also provided with a through-core tube 57, ...

Embodiment 3

[0071] like Figures 1~6 In, a construction method using the above-mentioned tunnel lining construction trolley, comprising the following steps:

[0072] S1, such as figure 1 In the middle, the tunnel lining construction trolley moves to the construction position through the track 11 and the traveling device 10, and the vertical form casts the second lining cavity 6 formed between the first lining 2 and the tunnel lining construction trolley template;

[0073] During construction such as image 3 In the method, a plurality of overcasting compensation devices 5 are set on the vibrating window 100 of the side mold 9 of the tunnel lining construction trolley. After the pouring and vibrating, each overcasting compensation device 5 is controlled to staggeredly expand and contract, and when retracted, the overcasting compensation device 5 is controlled. The telescopic disk 51 of 5 retracts into the surface of the formwork. When extending, the telescopic disk 51 extends beyond the ...

Abstract

The invention provides a tunnel lining construction trolley, a vibrating device and a construction method. The tunnel lining construction trolley comprises a trolley frame, a top formwork is arranged at the top of the trolley frame, and side formworks are arranged on the two sides of the trolley frame; a plurality of over-pouring compensation devices are arranged on the inner side of the top die, telescopic plates are arranged on the over-pouring compensation devices, at a telescopic position, the outer surfaces of the telescopic plates are flush with the outer wall of the top die, the telescopic plates are used for forming an over-pouring cavity during pouring, and the telescopic plates stretch out after pouring so that poured concrete can be compact or the surface of the poured concrete can be attractive; a displacement sensor used for detecting the position of the telescopic disc is further arranged. After pouring and vibrating, each over-pouring compensation device is controlled to stretch out and draw back in a staggered manner, so that the surface of the concrete is smooth; by adopting the structure of the over-pouring compensation devices, the over-pouring concrete during pouring can be utilized to compensate the void structure of the concrete, and the rubbing operation on the concrete can be realized and bubbles can be eliminated through the extension and retraction of the plurality of over-pouring compensation devices, so that the defects of voids and pitted surfaces on the appearance of the concrete are avoided.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a tunnel lining construction trolley, a vibrating device and a construction method. Background technique [0002] In the construction of the second lining of the tunnel, the tunnel lining construction trolley is usually used for construction. The existing scheme is to move the tunnel lining construction trolley along the track to the construction position and then cast the vertical form. After the initial setting, the tunnel lining construction platform is used. The hydraulic cylinder of the car is demolded. For example, Chinese patent document CN105156135A is a solution described in a tunnel lining trolley and its lining concrete pouring method. The existing problem is that honeycomb and pitted surface pouring defects are easily formed on the sidewall of the tunnel due to insufficient vibration. In the prior art, a post-repair solution is usually adopted, for example, a leak...
