Abstract

PROBLEM TO BE SOLVED: To provide a root-swelling disaster-preventive pile with C-steel and a multistage joint column and guard plate structure capable of simply coping with the prevention of a disaster, restoration construction or a disaster site having high dangerousness surely and safely in a short time. SOLUTION: The root-swelling disaster-preventive piles l with C-steel are formed in a pyramidal shape and the insides are formed in cavities, and a plurality of opening sections are formed to side walls. Cores with a plurality of wedge bodies, in which front ends are formed in an acute angle shape, are installed into the piles. T-shaped stoppers 6 are mounted at both ends of guard plates 5 with ribs resisting lateral pressure. When the root-swelling disaster- preventive piles with three-way C-steel and the root-swelling disaster-preventive piles with four-way C-steel are driven into a ground and each guard plate 4 in long size and short size is inserted from upper sections and assembled, a stout enclosure is manufactured instantaneously.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention causes landslides caused by typhoons, torrential downpours, etc., and floods in rivers, causing floods in rivers and other areas, causing severe damage due to floods in various places. Many people piled up a large amount of traditional sandbags day and night to prevent water intrusion to prevent water intrusion, but sandbags were instantly washed away by increasing water pressure. Therefore, the rooted disaster prevention pile with C-type steel, the multi-stage joint column, and the guard plate structure are easy to handle and sturdy in a place where there is an immediate battle in the event of a disaster. At the disaster site, lay the rooting pile. Use the gauge to open the gap, and lay the rooting disaster prevention pile in the soil up to the C-shaped steel part. A wide and thick core with a sharp tip that is attached to the inside of the pile and has a sharp tip that protrudes like a tree root from the opening in the side wall of the pile. When the installation is completed, the guard plate is inserted into the C-shaped steel of the left and right piles from above, and the guard plate is inserted into the enclosure type structure. Insert the guard plate into the cavity of the rooted disaster prevention pile and put a sandbag in the enclosure assembled with the guard plate to provide a more robust disaster prevention pile.

[0002]

2. Description of the Related Art A large amount of sandbags are piled up in order to prevent floods such as landslides caused by typhoons and torrential downpours in the previous year, floods in rivers and flood levees, etc. We are doing construction. In addition, even if a large number of sandbags are piled up at a high level in disaster recovery work where the water level increases and the danger increases, the current situation is that the soil is washed away by the increasing water pressure.

[0003]

Conventionally, the current disaster prevention measures that require urgency when the river rises are to pile up a large amount of traditional soil and to cope with water intrusion. In addition, the accumulation of sandbags requires a lot of human power, and there is a danger that the water will be instantaneously washed away by the increase of water pressure and water pressure at the place where the sandbags are piled up. Is also inconvenient. An object of the present invention is to improve the disadvantages and dangers and to provide an easy-to-assemble, short-time assembling and robust rooted disaster prevention pile.

[0004]

In order to solve the above-mentioned drawbacks and inconveniences, work at a disaster site where emergency is required or where human life is expected can be easily assembled by a small number of people in a short time. There must be. Accordingly, the present invention provides a disaster prevention pile with a C-type steel at the site of a disaster, a place where water is expected to increase, or a site where landslides are prevented from spreading. The hammer pedestal is put on the head of the disaster prevention pile, and this part is driven into the C-section steel. In addition, a sharp, wide and thick iron plate with a sharp tip at the end of the manufacturing process is installed in this pile, and a number of holes are opened in the side wall of the pile. Take root. In the case of double-casting, a special protruding square bar is inserted into the hollow part of the pile, and when it is brought into contact with the pile, many piles spread from the side of the pile in the soil, so the pile shakes. strong. After placing this rooted disaster prevention pile, a guard plate is inserted into the C-shaped steel part. By putting sandbags and gravel in the area surrounded by the guard plate, it becomes a more robust disaster prevention pile, preventing disaster recovery work and expanding the damage of the disaster, and providing a safe rooted disaster prevention pile guard structure with C type steel It is.

[0005]

[Function] In the present invention, the guard plate structure with the C-type steel rooted disaster prevention piles becomes a fence when the guard plate is made of wire mesh net. In order to provide a completely new wire mesh net fuence and C-type steel basement disaster prevention piles, which had never been seen before, by using wire mesh nets.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, numeral 1 indicates that the four-sided C-shaped steel is welded to 2 rooted disaster prevention piles. A small number of sharply-pointed roots are protruding from many holes on the four side walls below the disaster prevention piles. 2 in FIG. 2 is a three-way C-section steel. Fig. 3 is a three-way C
After placing the piled disaster prevention pile with steel and the four-way C-shaped piled disaster prevention pile into the ground, insert the four long and short guard plates from above, and assemble them. 4th
5 in the figure is a guard plate. Six T-shaped hooks are provided on the left and right sides of the guard plate. Reference numeral 7 in FIG. 5 denotes a four-way C-type steel joint column. 6 in FIG. 6 is a three-way C-type steel joint column. Fig. 7 is a diagram showing the state of use in which a disaster prevention pile with a C-type steel is laid in the soil. The three ridges protrude into the soil from the side wall of the disaster-prevention pile. It is the place where the three-way C-type steel joint column was erected on the disaster prevention pile in the place where it was inserted in the, and the guard plate was superimposed in two steps. FIG. 8 shows a wire mesh fence. Fig. 9 shows a casting interval gauge 9 in Fig. 9. First
Reference numeral 10 in FIG. 11 in FIG. 11 is a hammer base. In order to prevent the flooding of the river due to the typhoon torrential rain, the flooding, the collapse of the embankment, and the inundation of water into the houses, etc., this disaster prevention pile with C-shaped steel is cast at regular intervals, and the guard plate is inserted there. After the enclosure is made by assembling the guard plate, sandbags, gravel, etc. can be added to make a more durable breakwater wall several times more. To provide a structure and equipment that can be installed safely and easily in a short period of time for restoration work to prevent disasters in the event of emergency or prevent damage from spreading, and to cope with the rising water level with C-type steel joint columns and guard plates. There is something to do.
