[Detailed description of the device]

[0001]

[Industrial applications]

 This plan relates to a steel sheet pile that forms an upstanding retaining wall between H-shaped or I-shaped steel piles.

[0002]

[Prior Art]

 Conventionally, there are the following problems when retaining soil walls for sewerage works or building foundation works with an excavation depth of 2.5 m, for example, by installing pillar rows and horizontal sheet piles. Preliminary excavation is required to pull in the wood sheet pile, so the surrounding ground is loosened. In addition, it is not possible to construct with soil with high water level. The construction work on one day is extremely slow, and five people are required to attach the work. Since the wood sheet remains in the ground, it also causes the generation of termites.

[0003]

[Problems to be solved by the device]

 The purpose of this plan is to obtain a steel sheet pile that does not require pre-excavation, prevents the rock from loosening, and has a good waterproofing property and that can perform earth retaining work safely even in soil with a high groundwater level.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention uses H-shaped steel as a parent pile, stands between the parent piles, and engages the side edges with the opposing grooves of the parent pile. An iron sheet pile, which is removably provided and has metal fittings for connecting the upper and lower edges, which are provided detachably on the top and bottom of the slide metal fittings, replaces the H-section steel with the I-section steel as the main pile. The iron sheet pile described in the above invention. The iron sheet pile described in the first or second invention in which the vertical swing stop of the slide metal fitting is provided above and below the slide metal fitting. The iron sheet pile described in the first, second or third invention, respectively. The horizontal slide metal fitting is a rectangular plate body, and the bolt protruding from the rectangular steel plate is slidable in the lateral elongated hole formed in the slide metal fitting. The iron sheet pile according to the first, second, third or fourth invention, which is inserted into the iron sheet pile. The upper and lower edge connecting metal fittings are rectangular plate bodies with four corners cut off. The lower part of the metal fittings is pivotally supported on the upper edge side of the lower rectangular steel plate, and the vertical hole formed in the upper part makes the upper rectangular steel plate The iron sheet pile described in each of the first, second, third, fourth, and fifth inventions is formed so as to slidably insert a bolt provided on the lower edge portion side.

[0005]

[Action]

 In this plan, the parent piles 1 and 1 made of H-section steel or I-section steel 1'are driven into the ground at equal intervals, and the opposing grooves 20 and 20 of the adjacent parent piles 1 and 1 are made to oppose to each other. The side edge portion 3 of the rectangular steel plate 2 or the lateral slide metal fitting 5 is driven downward along the inner surface of the flange 20 ′, and the ground is excavated leaving the root insertion portion to form a retaining wall.

As the square steel plate 2 is cast and excavated, the upper square steel plate 2 is stacked on the lower square steel plate 2, and the upper and lower square steel plates 2 and 2 are connected to each other at upper and lower edge portions. 8 and 8 are connected and excavation proceeds.

First, the lateral slide metal fitting 5 is expanded and contracted according to the distance between the main piles 1 (tightly the distance between the main piles) and fastened with bolts 16. When the space between the facing grooves 20, 20 is larger than the lateral width of the rectangular steel plates 2, 2 when the square steel plates 2, 2 are driven down, the lateral slide metal fittings 5, 5 are slid to the outside. Place the slide metal fitting 5 along the inner surface of the flange 20 '(Fig. 11).

When the main piles 1 and 1 are driven in a slightly inclined state (FIGS. 12 and 13), the lateral slide metal fittings 5 and 5 can be used by appropriately expanding and contracting laterally.

In this case, the upper and lower rectangular steel plates 2 and 2 are laterally displaced, but the upper and lower edge connecting fittings 8 and 8 are tilted around the lower pivot bolt 16 and correspond to the tilt of the upper longitudinal hole 12. The upper bolt 16 slides along the vertically elongated hole 12 to cope with the lateral displacement. Further, a gap having a thickness equal to the thickness of the lateral slide fitting 5 is formed between the flange 20 'and the side edge portion 3 of the rectangular steel plate 2, and groundwater spouting from the gap is stopped by the water-stop projections 15, 15. To be done.

Further, when the square steel plates 2 and 2 are driven downward, the lateral slide metal fitting 5 can be prevented from tilting by the upper and lower ends of the protrusions 15 and 15 or the upper and lower vibration dams 14 and 14. It is possible to directly hold 21 on the projection 13 at the center of the rectangular steel plate 2.

[0011]

【Example】

 The H-shaped or I-shaped steel material 1'is used as the parent pile 1 and the horizontal slide metal fitting 5 can be freely attached to and detached from the square steel plate 2 standing between the parent piles 1 and 1 and the side edge 3 of the steel plate 2 facing the parent pile 1. And the upper and lower edge connecting metal fittings 8 are detachably connected to the upper edge 6 side, and the upper and lower connecting steel plates 2 and 2 are formed by the metal fittings 8 so that they can be slightly slid sideways. ..

The horizontal slide metal fitting 5 is a rectangular plate body, and includes a light slide metal fitting 5 for the uppermost stage and a slide metal fitting 5 used in the lower portion where earth pressure is applied. The lateral slide metal fitting 5 has two laterally elongated holes 10 formed in the longitudinal direction on both sides, and the uppermost metal fitting 5 has one laterally elongated hole 10 formed in the central portion longitudinal direction. It is slidable along the horizontally elongated hole 10 and is fastened and fixed by a high tension bolt 16.

The upper and lower edge connecting fittings 8 are rectangular plate bodies with four corners cut off, and have round holes 11 and vertically elongated holes 12 formed therein. Then, two connecting metal fittings 8 are provided on the front and back sides of the upper edge portion 6 of the steel plate 2. That is, the round hole 9 of the steel plate 2 and the round hole 11 of the metal fitting 8 are aligned and fixed by inserting the high tension bolt 16 into the holes 9 and 11, and connecting the other steel plate 2 to the upper end of the steel plate 2 in a standing manner. When this is done, the high tension bolt 16 is inserted into the vertically long hole 12 of the metal fitting 8 and the round hole 9 formed on the lower edge 6 ′ side of the steel plate 2 and tightened so that the horizontal sliding adjustment of the connecting steel plate 2 is possible. It is a thing. Further, in order to improve water blocking performance, round steel is welded to the side edge portion 3 side of the steel plate 2 at a position where the lateral sliding metal fitting 5 is not attached to form the water blocking projection 15.

As shown in FIG. 9 and FIG. 10, the steel plate 2 is sandwiched between the H-shaped steel main piles 1 and 1 which are preliminarily driven vertically at proper intervals according to the width dimension of the rectangular steel plate 2. Set the first-stage steel plate 2 with the edges 3 and 3 locked, stack the second-stage steel plate 2 on it, and sandwich the upper and lower steel plates 2 and 2 with the connecting metal fitting 8 from the front and back sides. High tension bolt Is inserted into and connected to the round hole 9 of the steel plate 2 and the vertically long hole 12 of the metal fitting 8 for connection, and the steel plates 2 and 2 are slidably lowered by the small pushing bar 17 through the attachment 18 to form a retaining wall.

At this time, the flange portion of the main pile 1 is in a state where the soil is removed mainly by the edge of the steel plate 2 and the lower edge, so that it is not necessary to clean the flange surface and friction resistance is small, so iron and iron The weight of the steel plates 2 and 2 is added to the slip and the blade is knife-cut by the high-tensile steel plate with a thickness of 10 m / m, so the force applied during insertion is only a slight force and the insertion is extremely smooth.

When the horizontal width of the steel plate 2 is insufficient with respect to the pitch length of the main piles 1 and 1 as shown in FIG. 11, the lateral slide fitting 5 is pulled out to compensate for the shortage. Further, when the steel plate 2 is in a state of being offset from the main piles 1 and 1 as shown in FIGS. 12 and 13, the steel plates 2, 2 and 2 in the upper, middle and lower stages are slightly shifted and set, but in this case, the upper and lower edges are set. Since the vertically elongated hole 12 on the upper side of the connecting fitting 8 is a long hole, the steel plate 2 is slid laterally to make a step-up connection at different steps.

Reference numeral 16 in the figure denotes a backhoe for excavation, and 17 denotes a machine for placing the rectangular steel plate 2, but the steel plate 2 can be pushed down and propelled by the tip of the backhoe 16. 18 'is abdominal, and 19 in FIGS. 6 and 7 is a tapered surface.

[Effect of the device]

 Since the present plan is configured as described above, when performing sewerage work or building foundation work with the steel plate 2 and the H-shaped or I-shaped parent pile 1, the parent piles 1 and 1 do not loosen the surrounding ground. The gap between pitches can be adjusted appropriately, and even in a tight condition, it is possible to make staggered connections to perform excavation and earth retention work such as burying water pipes on narrow roads quickly and easily. I will get it.
