Embodiment 1

[0044] Such as Figure 1-2 As shown, a mobile trolley for underground tunnel construction includes two trolley door frames 2 installed on both sides of the completed central column 12, and the two trolley door frames 2 pass through the support rods of the trolley workshop. 1 detachable connection, the running wheel 3 installed under the trolley door frame 2, and the matching track 4 installed on the track foundation 13 and adapted to the running wheel 3, on the trolley door frame 2 Suspension arms 14 protrude from the left and right sides respectively, and the suspension arms 14 are connected with a formwork frame 7, and hydraulic struts 5 and several common struts 6 are also arranged between the trolley door frame 2 and the formwork frame 7, A side wall formwork 8 is bolted to the formwork frame 7 .

[0045] Such as Figure 1-4 As shown, each of the trolley door frames 2 includes several trolley beams 21 parallel to each other, and each of the two ends of the trolley beams ...

Embodiment 2

[0049] Such as Figure 5 As shown, a construction method of a mobile trolley for underground excavation tunnel construction includes using any one of the mobile trolleys for underground excavation tunnel construction, including the following construction steps:

[0050] Step 1: Lay the track foundation 13, set the isolation layer, and pour the foundation concrete;

[0051] Step 2: install the supporting track 4 for trolley walking;

[0052] Step 3: Assemble the door frame 2 of the trolley and install the suspension arm 14, the hydraulic strut 5 and the running wheel 3;

Abstract

The invention discloses a movable type trolley for bored tunnel construction. The movable type trolley comprises a trolley portal frame, walking wheels mounted on the lower portion of the trolley portal frame and matched rails adaptive with the walking wheels. Suspension arms extend out of the left side and the right side of the trolley portal frame correspondingly, the suspension arms are connected with a formwork skeleton, and a hydraulic supporting rod is further arranged between the trolley portal frame and the formwork skeleton. In the bored tunnel construction process, if the movable type trolley is adopted to conduct construction, the formwork skeleton can be suspended on the trolley directly through the suspension arms, after the position of the formwork skeleton is adjusted and positioned through the hydraulic supporting rod, a formwork for construction can be directly mounted on the outer side of the formwork skeleton, after that, concrete is poured on the formwork and maintenance is conducted, construction is convenient and rapid, and thus the construction progress can be accelerated greatly. After construction is completed, the formwork is separated from the concrete, the trolley can directly walk to a next construction section to conduct construction after the formwork is taken back, the utilization rate of the device is high, and thus the construction cost is lowered greatly.

Description

technical field [0001] The invention relates to the field of tunnel and underground engineering construction, in particular to a mobile trolley for underground excavation tunnel construction and a construction method thereof. Background technique [0002] According to the excavation method of the tunnel, it can be divided into open-cut tunnel and underground tunnel. Because the open cut method greatly interferes with the surrounding environment and affects the normal traffic on the ground, it is becoming less and less applicable in the construction of urban rail transit. At the same time, the open cut method is more and more used in urban tunnels due to its strong adaptability to the modern urban environment. under construction. [0003] At present, the side walls, air ducts, and mid-slabs of underground excavation tunnels are usually constructed by erecting steel pipes with full supports and combined formwork. The main construction sequence is bottom slab → side walls → ai...
