[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0034] Reference Figure 8-11The preferred embodiment of the present invention provides a top shield dual-mold construction platform, comprising: a bottom support platform 2 arranged longitudinally along the shield direction, two support mold groups arranged laterally opposite to each other along the width direction of the bottom support platform 2, and two slide rails 6 serving as sliding support guides. The two support mold groups are respectively arranged to extend longitudinally, and the two slide rails 6 are respectively fixed to the top ends of the two support mold groups along the longitudinal direction. Each support mold group is supported on the bottom support platform 2 in a transverse sliding manner to adjust the track gauge between the two slide rails 6. Each support mold group is also arranged to be raised and lowered in the vertical height direction and deflected around the longitudinal line to adjust the support height and support angle of the two slide rails 6 accordingly.

[0035] When using the top shield dual-mode construction platform of the present invention, first install the bottom support platform 2 onto the bottom plate of the starting shaft, then adjust the two support module groups according to the design requirements to adjust the elevation, gauge and inclination angle of the two slide rails 6, then hoist the top shield machine 1 onto the new construction platform, and after assembly is completed, the top shield machine 1 starts construction; after the top shield machine 1 enters the hole, since the diameter of the pipe section 7 is smaller than the diameter of the top shield machine 1, the height of the slide rail 6 is raised by adjusting the height of the support module group to ensure that the center line of the pipe section 7 is consistent with the design axis; after the top pipe reaches the designed length, the top pipe-shield mode is converted, the top pipe in the starting shaft is removed, and then the elevation, gauge and angle of the two slide rails 6 are readjusted by adjusting the support module group to meet the transportation requirements of the battery car 8, completing the top pipe-shield dual-mode conversion in the starting shaft, and continuing the tunnel excavation operation in the shield mode.

[0036] The construction platform of the utility model has a simple structure and is safe to construct. The jacking-shield dual-mode conversion process is simple, the operation time is short, it is convenient and efficient, and it effectively solves the problem of the cumbersome conversion process of the existing jacking-shield conversion construction, which requires the dismantling of the jacking platform and the re-laying of the shield construction platform. It effectively reduces the difficulty and time of the jacking-shield mode conversion, improves safety and efficiency, and can realize four actions such as vertical jacking, left and right translation, lateral deflection, and longitudinal tilting (longitudinal tilting is realized by the different heights of the slide rails 6 on the left and right sides) by adjusting the supporting module, so as to meet the requirements of the construction platform in both jacking-pipe and shield modes of the jacking-shield machine, and provide a reference for the future conversion of jacking-shield tunnel construction modes in long distances and narrow spaces. It has strong versatility and good social benefits as well as good prospects for promotion and application.

Each group of formwork units is supported on the bottom support platform 2 along the horizontal sliding direction, and each group of formwork units is also arranged to be lifted vertically and deflected around the longitudinal line. The slide rail 6 is also fixed to the top of the multiple groups of formwork units in a formwork group.

Slide rails 6 are fixed to the left-right deflection devices 5. Therefore, in this optional solution, the track gauge between the two slide rails 6 can be adjusted by adjusting the lateral position of the lateral translation device 3 on both sides. The support height and longitudinal inclination of the two slide rails 6 can be adjusted by adjusting the lifting height of the vertical lifting device 4.

The sliding base is provided with a plurality of second latch holes spaced laterally. The first latches 303 pass through the second latch holes and the first latch holes 2011 to secure the sliding base to the crossbeam 201. By adjusting the position of the first latches 303 in the first latch holes 2011 at different locations, the fixed position of the lateral translation device 3 on the crossbeam 201 is adjusted accordingly, thereby adjusting the gauge between the two slide rails 6. The vertical jacking device 4 is mounted on the support base.

[0040] Furthermore, if Figure 1-2 As shown, the sliding base includes two sliding sleeves 302 that are slidably mounted on two adjacent beams 201. The outer wall of the sliding sleeve 302 is provided with a plurality of second pin holes that vertically penetrate the wall.

In this specific embodiment, the vertical jacking device 4 has a simple structure, is easy to manufacture, and has a low manufacturing cost. On the other hand, the jacking arm 401 is hollow and cylindrical, and the jacking arm 401 is vertically sheathed outside the jacking cylinder 402, and the top block 403 is fixed to the top end of the jacking cylinder 402. Therefore, through the cooperation of the jacking arm 401, the jacking cylinder 402, and the mounting sleeve 301, the lifting and lowering of the jacking arm 401 are guided and limited, thereby improving the stability and precision of the lifting and lowering of the jacking arm 401.

[0043] In the specific embodiment of this optional solution, Figure 5-7 As shown, the left-right deflection device 5 includes a rotatable seat 503, a mounting member fixed to the top of the rotatable seat 503, a positioning pin 507, and multiple second latches 506. The slide rail 6 is supported on and secured by the mounting member. The top center portion of the lifting arm 401 is recessed to form a receiving slot connecting the two opposing side walls. The rotatable seat 503 is positioned within the slot. The rotatable seat 503 is provided with a second positioning pin hole 502 and multiple fourth latch holes 501 extending therethrough. A positioning pin 507 passes through the first positioning pin hole 405 and the second positioning pin hole 502 to enable the rotatable seat 503 to rotate. The second latch 506 passes through the fourth latch hole 501 and the third latch hole 404 to secure the rotatable seat 503. In this specific embodiment, the rotatable base 503 is rotatably arranged with the locating pin 507 as the rotation axis, the rotatable base 503 is fixed to the lifting arm 401 by the second latch 506, and the rotatable base 503 is stably fixed at the corresponding deflection angle by inserting the second latch 506 into the fourth latch hole 501 at different positions.

[0044] Furthermore, if Figure 5-7As shown, the second positioning pin hole 502 is located above the rotatable seat 503. The rotatable seat 503 is rotatably mounted within the receiving slot, with a positioning pin 507, which passes through the second positioning pin hole 502 and the first positioning pin hole 405, serving as a rotation axis. A plurality of fourth latch holes 501 are located below the second positioning pin hole 502 and are sequentially spaced along the deflection arc of the rotatable seat 503. The rotatable seat 503 is secured by second latch pins 506, which pass through the corresponding fourth latch holes 501 and third latch holes 404.

[0045] Furthermore, if Figure 5-7 As shown, the mounting member includes a mounting base 504 fixed to the top of the rotatable drag seat 503, and a pressing plate 505 connected to the mounting base 504.
