レーンで吊り上げて移動するか、解体して運搬し
なければならないので、甚だ作業性が悪かつた。 With conventional waterway construction equipment, when moving to the next concrete placement site after placing concrete on both left and right walls, the formwork inside and outside the left and right walls must be lifted up by a crane and moved or dismantled. As the material had to be transported by hand, the workability was extremely poor.

このようなことから近時、レール上を走行可能

側壁の内・外面型枠を吊垂した水路型枠装置が開
発され、使用されている。 For this reason, a waterway formwork device has recently been developed and used, in which the inner and outer formwork of the left and right side walls of the waterway are suspended from the left and right sides of a gate-shaped structure that can run on rails. ing.

率が悪かつた。 However, although this channel formwork device is suitable for constructing straight channels, it is not possible to construct curved channels. Therefore, when constructing the left and right walls of a curved waterway, the formwork is assembled each time as in the conventional method, and after the concrete pouring is completed and the curing period has passed, it is dismantled and used for the next concrete pouring. The construction efficiency was extremely poor because the parts had to be transported to different locations and reassembled.

するものである。 The present invention has been developed in view of the above circumstances, and it is possible to move even if the waterway to be constructed is curved, and the inner and outer formwork of the left and right walls are set along the curve of the waterway and concrete is poured. After pouring concrete, the inner and outer formwork of the left and right walls are removed and the vehicle is moved, and after another curing period, the inner and outer formwork of the left and right walls are installed and the next step is carried out. It is an object of the present invention to provide a waterway formwork device that can be moved to a concrete placement site.

る。 Thereafter, the above-mentioned process is repeated, and concrete is poured intermittently on the side walls of the waterway in the order of ○A, ○B, ○C, and ○D, as shown in FIG. During this time, the curing period for the side wall of the part A, where the concrete was poured first, has finished, so the waterway formwork device from which the inner and outer formwork 12 and 13 have been removed is moved from the part D to the part A, and the jacking is completed. At step 9, the vertical frame 8 is lowered to the required height, and the inner and outer formwork 12 and 13 of the side wall of the section A are suspended from each geared trolley 11, and one end of each support jack 14 is attached to the inner and outer side walls. It is connected to the formworks 12 and 13. Then, the width stopper 25 between the ends of the horizontal end pieces of the inner and outer formworks 12 and 13 is removed, the camber 23 and the through square end pieces 24 are removed, and the end formwork 16 is demolded. Also, remove the width stopper 19 between the upper ends of the vertical thick materials of the inner and outer formworks 12 and 13, and remove the separator 20 between the middle and high parts and between the lower ends, and the wooden cone 2.
1. Connect the form ties 22, etc. to the inner and outer formwork 12, 13
Free from. Next, each support jack 14 is shortened and the inner and outer formworks 12 and 13 are rotated around their hanging support points to remove the mold, and the geared trolley 11 is run on the horizontal member 10. The inner and outer formworks 12 and 13 are moved inward and outward of the side wall. Next, the waterway formwork device 3 is used to form the inner and outer formworks 12 and 1 of parts B, C, and D during concrete curing.
3, run on the rail 2, and move to a position ahead of the part 2 where the concrete was poured, at an interval equal to the length of one concrete pouring, and here, the inner and outer formworks 12, 13 and The gable form 16 carried on the frame 4 is set along the curved reinforcing bars as described above, and the water stop plate 26 is placed in the groove 18 inside the gable form 16. , concrete 27 is placed inside the inner and outer formworks 12 and 13.
