Embodiment 1

[0072] This embodiment provides an auxiliary grouting device for tunnel trolley, which includes a connecting device and a supporting device, wherein, when the auxiliary grouting device for tunnel trolley is in use, the connecting device is used to connect the RPC grouting pipe and For the grouting machine, for example, the connection device can be connected to the grouting machine through a pressure-resistant grouting pipe. In this embodiment, the RPC grouting pipe is embedded in the concrete. When the grouting machine is working, the The grout is injected into the RPC grout pipe through the pressure resistant grout pipe.

[0073] Specifically, refer to figure 1 , the connecting device includes a rubber pad 3, a connecting sealing disc 4 and a quick connector 5;

[0074] The rubber pad is arranged under the concrete, and when an external force is applied to the connecting sealing disk, the connecting sealing disk exerts pressure on the rubber pad, thereby making the gap betwe...

Embodiment 2

[0123] refer to Figure 23 , the present embodiment provides a railway tunnel lining trolley belt mold grouting auxiliary grouting process, which includes:

[0124] The first step: the initial installation and modification of the trolley

[0125] The initial installation and modification of the trolley adopts different modification methods according to the use of different support devices; if the first support device is used, one or more support bases need to be set at an appropriate position on the top floor of the trolley, and other components of the first support device Install according to the relative position described in the first support device; if the second support device is used, it is necessary to set a support base at an appropriate position on the top floor of the trolley, and the other parts of the second support device are as described in the second support device. The above-mentioned relative position is installed; if the third support device is used, it is n...

Embodiment 3

[0154] refer to Figure 24 , the present embodiment provides a railway tunnel lining trolley belt mold grouting auxiliary grouting process, which includes:

[0155] The first step: the initial installation and modification of the trolley

[0156] The initial installation and modification of the trolley adopts different modification methods according to the use of different support devices; if the first support device is used, one or more support bases need to be set at an appropriate position on the top floor of the trolley, and other components of the first support device Install according to the relative position described in the first support device; if the second support device is used, it is necessary to set a support base at an appropriate position on the top floor of the trolley, and the other parts of the second support device are as described in the second support device. The above-mentioned relative position is installed; if the third supporting device is used, it i...

Abstract

The invention discloses a tunnel trolley auxiliary grouting device and process. The tunnel trolley auxiliary grouting device comprises a connecting device and a supporting device which is used for supporting the connecting device. The connecting device comprises a rubber blanket, a connecting sealing disc and a rapid connector. The connecting sealing disc is arranged on the supporting device and supported by the supporting device. The rapid connector is fixed to the connecting sealing disc. The rubber blanket is arranged between concrete and the connecting sealing disc. By adopting the tunnel trolley auxiliary grouting device for construction, the problems that in a lining trolley mold grouting process, since a surrounding rock is uneven and an open end assembly baffle cannot be completely sealed, consequentially, the open end cannot be completely filled, and disengaging defects exist in one side of the open end of an annular construction joint are solved, and therefore the problems such as disengaging of the tunnel vault annular construction joint and concrete defects are further solved; and the tunnel trolley auxiliary grouting device and process particularly have a defect pre-restoration effect on the connecting part of the annular construction joint.

Description

technical field [0001] The invention belongs to the field related to tunnels, and in particular relates to an auxiliary grouting device for tunnel trolleys and a grouting process, which solves the problems of tunnel vault voids and vault voids, especially the problem of tunnel ring construction joints. Background technique [0002] Our country is a mountainous country, so the amount of tunnels is also very large. In the tunnel lining (secondary lining) construction, due to the special position of the vault, the construction may be due to the reservation of pouring and unreasonable setting of plugging holes, the slump of the pumped concrete is large, the pressure of the pumped concrete is not well controlled, and the concrete Shrinkage, uneven support and other reasons will inevitably cause the second-lined vault and the concrete primary support surface to not adhere closely, and the concrete capping of the arch is prone to voids and cavities. Due to secondary lining defects...
