Description

Technical Field

[0002] The tunnel employs synchronous lining construction technology, with rail transport being the most common and efficient mode of transportation. Traditional TBM synchronous lining construction requires the installation of the trolleys outside the tunnel before transporting them inside. However, using a separate TBM synchronous lining construction method, the secondary synchronous lining equipment is appropriately separated from the TBM's supporting equipment and maintains a reasonable distance. The secondary synchronous lining equipment used on-site includes needle beam low sidewall trolleys, rebar trolleys, secondary lining trolleys, and curing trolleys, among other construction equipment.

The template pre-assembly area 300 is used for welding and splicing small template components on the pin beam inverted arch gantry and the secondary lining gantry. The template and accessory assembly area 400 is used for assembling each template module onto the gantry frame and welding and assembling accessories onto the gantry frame. The sorting and whole-machine storage area 500 is used for gantry operation testing and temporary storage.

[0082] In this embodiment, the present invention provides an installation method for a separate TBM synchronous lining construction trolley. First, the installation materials required for each trolley are stored outside the tunnel to prepare for the installation of the separate TBM synchronous lining construction trolley, saving time and improving installation efficiency inside the tunnel. Then, a logistics vehicle transports the materials to the installation area inside the tunnel. A crane and longitudinal lifting rails are installed above the installation area. The lifting rails are fixed to the top anchor support by I-beams. Lifting equipment is then installed on the lifting rails above the installation area. For example, there are two lifting rails, left and right, with two electric hoists on each side, for a total of four electric hoists, preparing for the subsequent movement and installation of various trolley components. Finally, an electric flatcar transports the installation materials for on-site pre-assembly, completing the separate TBM synchronous lining construction trolley installation within the installation area.

[0083] Specifically, the installation area can be divided into a gantry pre-assembly area, a frame assembly area, a template pre-assembly area, a template and accessory assembly area, and a sorting and whole machine storage area. The separate TBM synchronous lining construction trolley is installed in multiple areas, and the installation of various trolleys can be carried out simultaneously. Moreover, there is no need to transport the whole machine into the tunnel. The installation can be completed directly in the work area, which can effectively shorten the installation cycle and improve the installation efficiency.

A fourth traveling system is installed on the support trolley as the foundation for its movement, enabling precise and stable movement along tracks or other designated paths. Specifically, the fourth traveling system includes a drive unit, a transmission unit, and track wheels to ensure precise and stable movement of the equipment. In this installation method, the fourth traveling system, the fourth bottom longitudinal beam, the fourth gantry, the fourth upper longitudinal beam, and the connecting components are installed using a modular or prefabricated design, reducing on-site installation workload and significantly improving installation efficiency. Simultaneously, this installation method reduces vibration, noise, and wear caused by improper installation, improving the operating efficiency and lifespan of the support trolley. Installing the fourth traveling system onto the fourth bottom longitudinal beam, and then hoisting the fourth gantry to connect with the fourth bottom longitudinal beam, ensures the connection accuracy between components and the stability of the overall structure. Moving the support trolley to a designated storage area for debugging allows for concentrated resources for comprehensive performance testing and functional verification, resulting in a more rational installation layout.

[0126] Preferred, Reference Figure 16 and Figure 17 The installation method of the split TBM synchronous lining construction trolley, step S30 also includes the installation of the curing trolley, including:

[0133] The entire maintenance trolley was moved to the sorting and storage area 500 for testing.

[0134] This embodiment provides an installation method for a maintenance trolley. The fifth traveling system serves as the foundation for the trolley's movement, ensuring smooth and accurate movement on the track. The installation of the fifth traveling system, the fifth bottom longitudinal beam, the fifth gantry, the upper platform, the fifth upper longitudinal beam, and connecting components all employ modular or prefabricated designs, reducing on-site installation workload and significantly improving installation efficiency. The third upper ladder, the third lower ladder, and other accessories provide operators with vertical movement channels, facilitating easier movement between the various work platforms. The electrical system, specifically including motors, controllers, and sensors, controls the trolley's movement, the lifting and lowering of each work platform, and the switching of the spray pipes, achieving automated and intelligent control of the trolley. It is noteworthy that this embodiment provides an installation method for the maintenance trolley, enabling its specific installation. The specific control flow, action time, and travel path for the movement, lifting, and operation of each module of the electrical system can be implemented using programmable logic devices such as PLCs, and will not be elaborated further here. Sprinkler pipes are used for regular curing of hardened concrete to prevent excessive evaporation of moisture and subsequent shrinkage cracks. For example, at room temperature, concrete should be watered with sprinklers within 4-6 hours after pouring, 4-6 times a day for the first three days, and then 2-3 times a day thereafter, with a curing period of no less than 14 days. The fifth lower working platform, the third middle working platform, and the fourth upper working platform provide additional working space for the curing trolley, increasing its versatility. The entire curing trolley is installed modularly from bottom to top, resulting in high installation efficiency. After installation, it is moved to the sorting and storage area for testing, ensuring the stability and functionality of the overall structure. The rational layout of the entire curing trolley installation process improves installation efficiency.

[0135] The embodiments described above are merely examples of several implementations of the present invention, and are described in a relatively specific and detailed manner. The combinations of their technical effects and features will not be repeated here, but should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
