Embodiment
[0035] like Figure 1-3 Shown, a kind of narrow space concrete pouring method of the present invention comprises the following steps:
[0036] A. Set discharge opening 1, mobile gantry crane 2, collecting hopper 3 and transport vehicle 4 in the pouring starting point area. The mobile gantry crane 2 moves close to the inner wall of the pipe gallery. The mobile gantry crane runs inside 2 doors;
[0037] B. Formwork system 5 is set along the area to be poured;
[0038] C, the mobile gantry crane 2 moves to the initial position of the formwork system 5;
[0039] D. The collecting hopper 3 is arranged on the transport vehicle 4, and the transport vehicle 4 is located under the discharge opening 1, and the discharge opening 1 puts concrete slurry into the collecting hopper 3;
[0040] E. The transport vehicle 4 drives the collecting hopper 3 to move to the 2 places of the mobile gantry crane;
[0041] F. The mobile gantry crane 2 lifts the collecting hopper 3 to the formwork sys...

The invention discloses a narrow and small space concrete pouring method. The method comprises the steps that 1, a discharging outlet, a movable gantry crane, an aggregate bin and a transport cart arearranged at a pouring starting point region, the movable gantry crane is attached to the inner wall of a pipe gallery to move, and the aggregate bin and the transport cart are operated inside the movable gantry crane; 2, a template system is arranged along the to-be-poured region; 3, the movable gantry crane is moved to the initial position of the template system; 4, the aggregate bin is arrangedon the transport cart, the transport cart is located below the discharging outlet, and concrete grout is placed into the aggregate bin through the discharging outlet; 5, the transport cart drives theaggregate bin to move to the movable gantry crane; 6, the movable gantry crane lifts the aggregate bin to move to the template system, and the aggregate bin injects concrete grout into the template system; 7, the movable gantry crane moves along the setting region of the template system to enter the next pouring region, and the steps D-F are executed repeatedly. The method meets the requirement for high precision and efficiency, all needed equipment and tools can be recycled, and resource waste is avoided to the maximum extent.
Description
technical field [0001] The invention relates to the engineering field, in particular to a concrete pouring method in a narrow space. Background technique [0002] The escape channel pipe gallery and pipeline installation pipe gallery of submarine immersed tube tunnels are generally narrow spaces with a cross-sectional width and height of 3m×3.5m, and it is difficult to deploy engineering equipment. It is in the subsea immersed tube tunnel, which is not only narrow but also long and narrow. The pouring volume is large and the accuracy is high. Using manual pouring will greatly reduce the accuracy and efficiency. However, there was no mature construction plan in this field that could guarantee both pouring quality and efficiency, which can be said to be blank. Contents of the invention [0003] The purpose of the present invention is to overcome the conventional concrete pouring method in the existing narrow space, which is generally time-consuming and labor-intensive, espe...
