[0066] The movable formwork system (100) for constructing a retaining wall according to the present invention further comprises a movable wheel (130) that can be attached to and detached from the lower part of the formwork form (120).

[0067] As shown in FIG. 3, a plurality of concave wheel grooves (1211) are formed in the lower part of the form body (121) of the formwork form part (120) spaced apart along the longitudinal direction, and the movable wheels (130) are inserted into each wheel groove (1211) so that a plurality of movable wheels (130) can be detachably installed in the lower part of the form body (121).

[0068] The above-mentioned moving wheel (130) has a wheel (133) and is provided with a wheel projection (131) on its upper side that is inserted into the wheel groove (1211). The moving wheel (130) is installed so that the wheel projection (131) is inserted into the wheel groove (1211) formed in the foam body (121), and the moving wheel (130) is installed so as to be detachably attached to the lower part of the foam body (121).

[0069] One or more of the plurality of moving wheels (130) installed at the bottom of the above-mentioned foam body (121) may be equipped with a driving motor (135) that drives the wheel (133). The driving motor (135) is provided as a motor capable of forward and reverse rotation.

[0071] In the movable formwork system (100) for constructing a retaining wall according to the present invention, a formwork form section (120) is installed on the upper part of a foundation section (C), and a frame section (110) is installed along the length direction in which the retaining wall is to be constructed, on the outer side of the formwork form section (120) in the width direction.

[0072] After the retaining wall is cured on the upper part of the foundation (C) by the above formwork form part (120), the tie rod (127) of the formwork form part (120) is removed. Then, the lifting part (125) provided in the formwork form (120-1) is operated to lift the form body (121), and a plurality of detachable moving wheels (130) are installed in the wheel groove (1211) formed in the lower part of the form body (121).

[0073] By operating the lifting unit (125), the form body (121) is raised so that the body guide member (123) approaches or comes into contact with the upper roller (1171), and the lower roller (1173) is installed on the frame body (111) so that it moves upward to approach or come into contact with the lower part of the body guide member (123). The formwork form (120-1) is supported by the upper roller (1171) and the lower roller (1173).

[0074] The above formwork (120-1) is supported by the upper roller (1171) and the lower roller (1173) and is provided on a moving wheel (130) at the bottom of the formwork body (121), so that the formwork (120-1) moves in the longitudinal direction by the rolling of the wheel (133).

[0075] After the above formwork form (120-1) is moved, the lifting unit (125) operates to raise the form body (121), the moving wheel (130) is removed, and the lifting unit (125) operates again to lower the form body (121) so that it comes into contact with the ground (G). Next, a tie rod (127) is installed between the formwork forms (120-1) located on both sides, and after supporting the formwork form section (120) with the support unit (115), concrete is poured. The above process is repeated until the construction of the retaining wall is completed.

[0076] To briefly explain the operation of the lifting member (125) during the movement process of the above formwork section (120), when the adjusting member (1257) in FIG. 4 is rotated in one direction, the distance between the two nut members (1253) becomes closer and the distance between the upper and lower hinge connecting members (1255) becomes farther, and when the adjusting member (1257) is rotated in the opposite direction, the distance between the two nut members (1253) becomes farther and the distance between the upper and lower hinge connecting members (1255) becomes closer.

[0077] In a state as shown in Fig. 4, when the adjusting member (1257) is rotated in one direction to bring the distance between the two nut members (1253) closer, the lower hinge connecting member (1255) or the lifting member (1259) connected to the hinge connecting member (1255) moves downward, pushing the ground (G) and the foam body (121) rises.

[0078] With the foam body (121) in a raised state, a wheel projection (131) is inserted into the lower wheel groove (1211) to install a moving wheel (130) on the lower part of the foam body (121). Then, the adjusting member (1257) is rotated in the opposite direction to raise the hinge connecting member (1255) or the lifting member (1259) connected to the hinge connecting member (1255) so that it falls off the ground (G).

[0079] In this way, if a moving wheel (130) is installed on the lower part of the foam body (121), the foam body (121) can be moved to the next work position along the length direction by human power. Additionally, if a driving motor (135) is provided on one or more of the moving wheels (130), the foam body (121) can be moved by driving the driving motor (135).

[0080] After moving the formwork section (120) to the next work position using the above-mentioned moving wheel (130), the adjusting member (1257) is rotated in one direction to raise the formwork body (121), the moving wheel (130) is detached from the bottom, and the adjusting member (1257) is rotated in the opposite direction to lower the formwork body (121) to the foundation section (C) and proceed with the next work. Since the moving wheel (130) can be installed at the bottom of the above-mentioned formwork section (120), the movement of the formwork section (120) is easily achieved.

[0082] As described above, according to the movable formwork system (100) for retaining wall construction according to the present invention, after curing, the formwork form section (120) is lifted and a moving wheel (130) is mounted on the lower part so that only the formwork form section (120) can be moved to construct the next section, so construction is easy and quick, installation costs are reduced, and there is no need to construct the width of the foundation section (C), which is the foundation concrete, wider than necessary to improve mobility.
