Embodiment

[0041] see Figure 1-Figure 4 , the present invention provides a mobile formwork 1 for pouring the central water ditch of the tunnel. This mobile mold base 1 includes a mold assembly 11 , a traveling assembly 12 , a bracket assembly 13 and a positioning assembly 14 . The mold assembly 11 is used to cooperate with the formed area to form a space to be poured, the walking space is used to drive the movable mold base 1 to move, the bracket assembly 13 is used to support the mold assembly 11, and the positioning assembly 14 is used to make the mold assembly 11 relative to the bracket assembly. 13 produces relative movement.

[0042] The mold assembly 11 includes a first die plate 112 , a second die plate 114 and a telescopic piece 116 .

[0043] The first template 112 and the second template 114 are disposed opposite to each other, and an area to be poured is formed between the first template 112 , the second template 114 and the formed area. One end of the telescopic element 1...

Abstract

The invention relates to the field of tunnel construction equipment, in particular to a movable formwork and a pouring method for pouring a tunnel central ditch. The movable formwork for pouring the tunnel center ditch includes a mold assembly and a walking assembly; the mold assembly includes a first template and a second template, the first template and the second template are disposed oppositely, and the first template and the second template can be close to or away from each other; and the walking assembly is connected to the mold assembly, and the walking assembly can drive the mold assembly to move. The pouring method for pouring the tunnel center ditch includes the following steps that a, the movable formwork is operated until the mold assembly moves into an area to be poured; b, concrete is poured; c, demoulding is performed after the center ditch is formed; and d, the movable formwork is operated until the mold assembly moves to a next area to be poured. The movable formwork and the pouring method for pouring the tunnel center ditch have the advantages of rapid transition, low labor intensity and easy organization.

Description

technical field [0001] The invention relates to tunnel construction equipment, in particular to a mobile formwork used for pouring a central water ditch in a tunnel and a pouring method. Background technique [0002] The concrete pouring of the tunnel center ditch adopts the whole or small combined formwork. The formwork is assembled first and then installed and positioned. After the concrete is formed, the formwork is removed when the strength meets the requirements. The formwork is manually transferred, and then the formwork is reassembled and installed, and the next section of the center is started. Construction of the ditch. [0003] Each cycle of this construction method requires dismantling, cleaning, transfer, installation and positioning of the formwork, complicated procedures, long cycle time, time-consuming and laborious reinforcement and support, poor integrity, high labor intensity, and difficult to guarantee civilized construction. SUMMARY OF THE INVENTION ...
