Embodiment 2

[0038] Embodiment two is basically as attached image 3 And attached Figure 4 As shown, the only difference from Embodiment 1 is that it also includes at least one translation trolley 6 that can walk on the self-propelled trestle 3, and the self-propelled trestle 3 is provided with a second walking rail for the translation trolley 6 to walk, and the translation trolley 6 The shape is an arc designed to imitate the arc of the tunnel vault. The bottom of the translation trolley 6 is equipped with track wheels. Positioning device, jackhammer positioning device and manipulator.

[0039] After the self-propelled trestle 3 walks out, the translation trolley 6 walks on the second walking rail for construction, and the workers enter the liftable working platform of the translation trolley 6, and place materials such as anchor rods and arches on the translation trolley 6. According to the construction requirements, control the lifting of the liftable working platform and the manipul...

Embodiment 3

[0040] Embodiment three, basically as attached Figure 5 And attached Figure 6 As shown, the only difference with Embodiment 2 is that it also includes the excavation and arch installation trolley track 7 walking inside the self-propelled trestle 3, and the self-propelled trestle 3 is provided with a trolley track for excavation and arch installation. 7. The second track for sliding, the trolley track for excavation and arch installation Car track 7 front end bottoms are provided with the second crawler dolly support 5, and excavation and arch frame installation trolley track 7 and the second crawler dolly support 5 are all controlled by control mechanism.

[0041] After the excavation and arch installation trolley track 7 advances to the tunnel face, it is supported by the second crawler trolley support 5 after it travels, and the control mechanism controls the translational trolley 6 to move longitudinally on the third travel track to the tunnel face , Construction is car...

Embodiment 4

[0042] Embodiment four, basically as attached Figure 7 And attached Figure 8 As shown, the only difference from Embodiment 1 is that it also includes an integral inverted arch template 8 that can walk outside the self-propelled trestle 3 and is controlled by a control mechanism. Ditch mould, the self-propelled trestle 3 is provided with the 4th walking rail for integral type inverted arch formwork 8 walking, and self-propelled trestle 3 and integral type inverted arch template are detachably connected.

[0043] Since the existing inverted arch formwork generally only has side molds, only the two ends of the inverted arch after forming are arc-shaped, and the concrete self-leveling plane in the middle is a combination of inverted arches at different positions, so that the inverted arch, arch wall and side wall cannot form a single It is a complete arc closed loop, and it takes time and effort to install the inverted arch formwork and side forms. The setting of this device ca...

Abstract

The invention belongs to the field of tunnel construction facilities, and particularly discloses a tunnel construction comprehensive trolley. The tunnel construction comprehensive trolley comprises a control mechanism, and further comprises a railway laid in a tunnel and a tunnel construction comprehensive trolley body which is controlled by the control mechanism and runs on the railway. The tunnel construction comprehensive trolley body comprises a secondary lining steel bar trolley body and a geotechnical cloth waterproof plate trolley body which are arranged in sequence from the tunnel portal to the heading face. A self-walking trestle and a first walking rail which allows the self-walking trestles to walk are arranged in the secondary lining steel bar trolley body and the geotechnical cloth waterproof plate trolley body. The lower part of the front end of the self-walking trestle is provided with a first crawler belt trolley support base. The self-walking trestle and the first crawler belt trolley support base are controlled by the control mechanism. According to the scheme, the self-walking trestle is placed in the secondary lining steel bar trolley body and the geotechnical cloth waterproof plate trolley body, the secondary lining steel bar trolley body and the geotechnical cloth waterproof plate trolley body can balance weight for the self-walking trestle, the phenomenon of deformation and unsafe construction generated by deliberately prolonging the self-walking trestles for reaching a standard length are avoided.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction facilities. Background technique [0002] China's tunnel construction projects are usually carried out in the following order: 1. The construction of the side and inverted arch before entering the hole; 2. The construction of the large pipe shed ahead of time; 3. The measurement, positioning and setting out; 4. Drilling , blasting; 5, slag removal, bolting, arch (support), concrete spraying (including initial spraying and supplementary spraying); 6, advanced anchoring (after the pipe shed section); 7, measuring and setting out; and When excavating grade V surrounding rock, the safety distance is required to be no more than 90 meters from the concrete lining of the second lining to the operation face; The distance between the concrete lining and the face of the tunnel requires the use of equipment such as the second lining reinforcement trolley, the geotextile waterproof board trolley,...
