Description

  The present invention relates to a simple retaining wall and a construction method thereof, and more particularly, to a simplified retaining wall and a construction method thereof that can be easily constructed and ensure sufficient strength.

  Conventionally, when constructing an underground structure or the like, a retaining wall has been provided to prevent the surrounding ground of the excavation site from collapsing. This mountain retaining wall has been reinforced such as a beam cutting method and an anchor method because there is a risk of deformation or collapse due to earth pressure on the surrounding ground.

  Here, the timber beam method is to provide an abdomen that supports the retaining wall on the inner side surface (surface on the excavation site side) of the opposing retaining wall, and hang a horizontal beam between these erections. It is a construction method that reinforces the facing mountain retaining wall. On the other hand, the anchor construction method is a construction method in which the anchoring wall is reinforced by using the frictional force between the anchor and the ground by driving the anchor toward the surrounding ground from the inner side surface of the retaining wall.

  As described above, in the conventional method of constructing the retaining wall, since a cut beam is spanned in the excavation site, it is difficult to secure a sufficient working space, or a heavy machine is required when driving an anchor. As a result, there are problems such as a reduction in work efficiency and an increase in work costs.

Then, the construction method of the retaining wall as shown in patent document 1 is provided. In this construction method, a mountain retaining wall is constructed by fitting a horizontal sheet pile between the H-shaped steel piles that are driven into the ground at predetermined intervals. The deformation suppression effect of the horizontal sheet pile is transmitted to the central portion of the retaining wall by this H-shaped steel pile, and the rigidity of the retaining wall is ensured. And since the cross sheet pile is provided along the wall surface of the retaining wall, the reinforcing member does not cross in the plane of the excavation site, and a work space in the excavation site can be sufficiently secured. It is.

As shown in FIG. 44, the mountain retaining wall 800 according to the eighth embodiment includes a support 802 embedded in a facing inclined surface 801 formed by excavation of the ground and a standing formwork panel 10 at a branch line 803. It is constructed by refilling earth and sand in the space formed by the inclined surface 801 and the formwork panel 10. A plurality of struts 802 are embedded in accordance with the height of the standing formwork panel 10, and a concrete layer 805 is placed on a root cutting bottom 804 formed by excavation of the ground. In the concrete layer 805, runners 806 are fixed with concrete nails 807 at predetermined positions away from the respective inclined surfaces 801.

  On the runner 806, the formwork panel 10 is juxtaposed, and the lower part of the formwork panel 10 is fixed with a runner 806 and screws 808. A cap 811 is attached to the upper part of the formwork panels 10 arranged side by side, and a runner 806 is attached on the cap 811, and each is fixed with a screw 808. By repeating this operation, the formwork panels 10 are stacked to a predetermined height, and only the cap 811 is attached to the uppermost formwork panel 10 to maintain the horizontality and linearity of the formwork panel 10.

  A branch line 803 is passed through a hole provided in the mold panel 10, and the branch line 803 is fastened to a support column 802 embedded in the inclined surface 801, thereby fixing the mold panel 10 and the support column 802. An intermediate width stopper cap 814 and a width stopper cap 815 are installed between the facing formwork panels 10. The intermediate width stopper cap 814 is installed at a substantially central portion of the facing mold panel 10, and the width stopper cap 815 is installed at the uppermost portion of the stacked mold panels 10. The intermediate width stopper cap 814 and the width stopper cap 815 can prevent the mold panel 10 from falling down due to the side pressure applied to the mold panel 10 when the earth and sand are backfilled.

Next, with reference to FIG. 45 to FIG. 50, the construction procedure of the retaining wall according to the fourth embodiment will be described.
FIG. 45 is a flowchart showing the construction procedure of the retaining wall according to the eighth embodiment, and FIGS. 46 to 50 are diagrams showing the states of the construction steps of the retaining wall according to the eighth embodiment.

  First, as shown in FIG. 46A, a space for excavating the ground, rolling the excavated surface, and backfilling is secured (step S800). Next, as shown in FIG. 46B, a concrete layer 805 is formed by placing crushed stone and discarded concrete on a rooted bottom 804 formed by excavation (step S801). Next, the runner 806 is fixed with a concrete nail 807 at a predetermined distance from the inclined surfaces 801 on both sides formed by excavation (step S802). Next, as shown in FIG. 47, the formwork panels 10 are juxtaposed on the runners 806 (step S803). And the lower part of the formwork panel 10 and the runner 806 are fixed with the screw 808 (step S804).

  Then, a runner 806 and a cap 811 are attached to the upper part of the standing formwork panel 10 and fixed with screws 808 (step S805), and a lateral end thick member 812 is attached to the surface side of the formwork panel 10 (step S806). Then, while fixing the lateral end thick member 812 with the branch line 803, the branch line 803 is passed through the insertion hole formed by opening the lid 14 provided on the mold panel 10 (step S807). Here, the runner 806 and the cap 809 attached to the upper part of the formwork panel 10 cover the runner 806 on the upper part of the formwork panel 10 as described above, and the cap 809 is installed on the upper surface of the runner 806, The cap 809 is fixed with screws 808. Next, the support column 802 is embedded in each inclined surface 801 (step S808), and the branch line 803 and the support column 802 are fixed (step S809).

  Next, as shown in FIG. 48, the formwork panel 10 is stacked on the runner 806 and arranged side by side (step S810), and the cap 409 and the runner 406 are fixed to the upper part of the formwork panel 10 with screws. The formwork panels 10 are stacked until reaching a predetermined height (step S811 / NO). When the formwork panel 10 is stacked to a predetermined height (step S811 / YES), as shown in FIG. 49, an intermediate width stop cap 814 and a width stop cap 815 are installed between the formwork panels 10 facing each other. As shown in FIG. 50, earth and sand are buried back in the space between the formwork panel 10 and the inclined surface 801 to construct a simple mountain retaining wall 800 (step S812).

  In the mountain retaining wall and its construction method according to the eighth embodiment, the formwork panel 10 can be stacked according to the height of the excavated ground, and the upper and lower sides of the stacked formwork panel 10 are fixed by the cap 89 and the runner 806. be able to. For this reason, even if the formwork panel 10 is piled up, sufficient strength can be obtained and the side pressure of the earth and sand can be sufficiently resisted. Since reinforcing bars can be placed between the facing formwork panels 10 and concrete can be placed, construction of the formwork for placing the retaining wall and the concrete can be realized at the same time.

  From the above description, in the method of constructing the simple retaining wall according to the present embodiment, the support is embedded in the inclined surface formed by excavation, the standing formwork panel is fixed with the branch line, and the inclined surface and the formwork are fixed. A simple mountain retaining wall can be constructed by backfilling earth and sand between the panels. Thereby, a mountain retaining wall can be easily constructed using existing members without requiring heavy machinery or a large work space.

  And just by fixing the horizontal end thick member arranged on one side of the formwork panel with a branch line, it can fully withstand the lateral pressure of earth and sand, and the formwork is arranged in parallel at the position facing this formwork panel By doing so, since concrete can be placed, work efficiency can be improved.

  Furthermore, since it is possible to construct the retaining wall by stacking the formwork panels according to the excavated underground height, it is possible to cope with the construction of various retaining walls.
