Embodiment 1

[0036] Example 1, such as Figure 1-3 Shown:

[0037] A turning mechanism suitable for a fabricated underpass tunnel, comprising a clamping part 1 for clamping the prefabricated member 13 and a first supporting seat 2 and a second supporting seat 3 for supporting the clamping part 1, so The clamping member has a clamping space through which the prefabricated member 13 can penetrate vertically. The first support base 2 and the second support base 3 are arranged opposite to each other and rotate and cooperate with the support member. A supporting base 2 and / or a second supporting base 3 is also provided with a driving member for driving the clamping member 1 to rotate, and a plurality of supporting rods passing through the clamping space are also provided on the clamping member 1 4. The support rod 4 is used to support the prefabricated member 13 in the vertical direction, and the support rod 4 is detachably connected to the clamping component 1.

Embodiment 2

[0048] Example 2, such as Figure 1-3 Shown,

[0049] A method for prefabricating tunnel frame members using the above-mentioned turning mechanism,

[0050] Step 1. Design steps: In the design stage, divide the frame members of the tunnel to be constructed into W-frame and M-frame in the horizontal direction;

[0051] Step 2: Making the pouring mold: make W-frame pouring mold or M-frame pouring mold;

[0052] Step three, pouring: pouring the W-frame and M-frame in the W-frame pouring mold or M-frame pouring mold in step two;

[0053] Step four, component flip:

[0054] When the pouring mold is a W-frame pouring mold, hoist the poured M-frame into the clamping space of the turning mechanism, and then start the driving device of the turning mechanism to turn the clamping part 1 through 180°, so that the M-frame is installed form;

[0055] When the pouring mold is an M-frame pouring mold, hoist the poured W-shaped frame into the holding space of the turning mechanism, and then start the dr...

Abstract

The invention relates to the technical field of construction engineering, specifically relates to a turnover mechanism suitable for an assembly type under-crossing tunnel and a turnover method. The turnover mechanism comprises a clamping part, a first supporting base and a second supporting base, wherein a clamping component is provided with a clamping space which a prefabricated component can penetrate in the vertical direction, the first supporting base and the second supporting base are oppositely arranged and are rotationally matched with a supporting part, the first supporting base and / orthe second supporting base is further provided with a driving part for driving the clamping part to rotate, a plurality of supporting rods penetrating through the clamping space are further arrangedon the clamping part, the supporting rods are used for supporting the prefabricated component in the vertical direction, and the supporting rods and the clamping part are detachably connected. According to the turnover mechanism, the turnover efficiency is greatly improved, the labor intensity of workers in the turnover process is also reduced, the damage risk of the prefabricated component is reduced, and the construction risk of workers is reduced as well.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, in particular to an overturning mechanism and an overturning method suitable for an assembled underpass tunnel. Background technique [0002] In the field of construction engineering technology, in the construction of urban underpass tunnels, tunnel components are usually cast in situ and prefabricated. For cast-in-situ methods, due to the need for a longer maintenance period, it is not conducive to shortening the construction period. For tunnels under tunnels, prefabricated construction methods are usually adopted. [0003] For the prefabrication of tunnel components by prefabrication, although the construction period can be greatly shortened, in the further construction design, the inventor found that the current tunnel component prefabrication construction still has shortcomings, specifically: [0004] As the tunnel components are usually large in volume and weight, the turning proces...
