Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a retaining method, particularly to a method for placing backfill concrete between a parent pile and an upright.

Conventionally, in mountain retaining construction, when using parent piles and horizontal sheet pile construction methods for retaining walls, and using struts or earth anchors as retaining supports, it is difficult to transfer the load between the parent piles and the uprights. For this purpose, a method of placing backfill concrete is generally used.

Conventionally, as back-filling concrete formwork for Yamadome-haraori, the formwork is attached using plywood and crosspieces. ) Fill a plastic bag with concrete or mortar and attach it to the stand with wires, etc. Methods such as ) have been used, but method ) has the drawbacks of being expensive, time-consuming, and takes time to dismantle and clean up the formwork. It was difficult to deal with this problem, and the contact area between the raised and parent piles and the concrete tended to be small, leading to concerns about strength and poor appearance.

The present invention was proposed in order to eliminate such drawbacks, and involves cutting a wire mesh curved into a groove shape to match the spacing between the parent pile and the upright to form a backing concrete form. This method relates to a retaining construction method characterized in that the formwork is interposed between the parent pile and the upright, and then concrete is poured into the formwork.

In the present invention, as described above, a wire mesh curved into a groove shape is used, and this is cut to match the spacing between the parent pile and the upright to form a back-filled concrete mold, and the same formwork is attached to the parent pile. It is interposed between the pile and the riser, and is formed between the bottom piece and both side pieces of the same groove-shaped formwork, and the facing surface of the parent pile and the riser that closes both ends of the same formwork. Concrete was placed in the space to transfer the load between the parent pile and the upright.

As described above, according to the present invention, the concrete formwork interposed between the main pile and the upright is constructed by cutting a wire mesh curved into a groove shape to match the spacing between the main pile and the upright. Therefore, the depth of concrete backfilling can be easily adjusted, which is particularly advantageous when the depth of backfilling is large. In addition, since the contact area with the parent pile and the upright can be secured to a predetermined size, there is no need to worry about the strength. Furthermore, the formwork can be installed easily and quickly, and materials such as veneer and crosspieces are not used, so there is no need for disassembly, clearing, and disposal of leftover materials.

In addition, since the material of the formwork is wire mesh bent into a groove shape in a factory, etc., it has a good appearance, can be stacked compactly, does not require a special storage space, and is easy to transport. has many advantages.

The present invention will be described below with reference to the illustrated embodiments.

A is a channel-shaped wire mesh that is bent in a factory or the like, and is cut with a wire cutter or the like to form a backing concrete formwork 3 in accordance with the spacing between the parent pile 1 made of H-shaped steel and the upright 2.

Next, as shown in FIGS. 1 and 2, the formwork 3 is mounted between the parent pile 1 and the riser 2 on the riser bracket 4 fixed to the flange of the parent pile 1, and then The formwork 3 is filled with concrete or mortar packed in a plastic bag. 5 in the figure is a horizontal sheet pile.

In addition, if the tilting bracket is not attached to the main pile 1, the formwork support reinforcing bars 6 are welded to the flanges of the main pile 1, and the formwork 3 is mounted on the reinforcing bars 6. . (See Figures 3 and 4) Although the present invention has been described above with reference to embodiments, the present invention is of course not limited to such embodiments, and various modifications may be made without departing from the spirit of the present invention. The design can be modified.
