Problems solved by technology
Because there is not enough space for a single well to transport segments, the previous construction experience is that a split start scheme is generally adopted for a single well, but the split start has many construction procedures, extremely low construction efficiency, high input costs, and serious lag Disadvantages such as construction period

Embodiment Construction
[0023] The present invention will be further described below in conjunction with accompanying drawing:
[0024] see Figure 1 to Figure 5 .
[0025] The shield machine single-well overall initiation construction method provided by the present invention comprises the following steps:
[0026] (1) Clean up the launch shaft, position and install the launch frame 9 close to the front launch portal in the launch shaft, then lift the shield machine components, and complete the assembly of the shield machine in the launch shaft;
[0027] (2) Install the reaction force frame 10, and install the cross brace 11 for supporting the reaction force frame 10 between the reaction force frame 10 and the rear tunnel doorway, between the reaction force frame 10 and the excavated tunnel doorway The spacing is enough for the segments to pass through;
[0028] The reaction frame 10 is generally composed of two upright columns and two upper and lower beams. The parts are connected by high-strengt...

The invention discloses a shield machine single well overall originating construction method. The method includes the following steps that 1 originating well is cleaned, an originating frame is positioned and installed in the originating well, a shield machine component is lifted, and the assembly of the shield machine component is completed in the originating well; 2 a reaction frame is installed; 3 a duct piece transporting bogie guide rail is installed on the bottom of the originating well; 4 two box girders used for supporting a shield handcar to travel are erected between the reaction frame and a dug tunnel door; 5 a mini-size door lifting device is installed, support stand columns arranged on two traveling beams of the mini-size door lifting device are fixed to the two box girders, and the two traveling beams are parallel to the axial direction of the shield machine; 6 a slurry discharging pipeline is installed. The technology is simple, easy to implement, and takes fully use of the limit space in the originating well; by cooperating the mini-size door lifting device with the duct piece transporting bogie guide rail, duct pieces can be transported to a piece feeding machine rapidly and continuously, and the single well overall originating of the shield machine can be achieved.
Description
technical field [0001] The invention relates to the technical field of shield tunneling method construction, in particular to an integral starting construction method for a single well of a shield tunneling machine. Background technique [0002] With the acceleration of China's urbanization process, the pressure brought by the increase of urban population to urban traffic is becoming more and more obvious. However, the development of urbanization must not be constrained by traffic pressure. Therefore, underground transportation corresponding to our traditional ground transportation has become a new channel to relieve urban traffic pressure. There is no doubt that subway transportation is a green project and is in line with China's sustainable development strategy. Therefore, our country urgently needs to develop transportation resources characterized by subways. Its development will not only meet the needs of urban development, but also the inevitable development of undergr...
