Description

[Detailed description of the invention] The present invention relates to a guide for square walls that allows the wall core to be exposed and the wall pile to be buried along the wall core when installing square wall piles. be.

The most important point in wall pile construction is the continuity of the wall pile. Therefore, the ruler used to construct a continuous wall requires the most precision.

Previously, for example, according to Special Publication No. 54-22684, the first
As shown in Figures A and B, continuous direction rulers 1 and 1 made of H steel were used to maintain a constant width interval necessary for constructing square wall piles 2 on both sides of the wall core. 3, 3 is a displacement direction ruler. However, when constructing a wall pile on a slope, according to the conventional method, H steel rulers 1 and 3 are assembled and installed in a well, as shown in Figure 2.
In addition, when constructing stage 4 on the river side due to heavy machinery being unable to be brought in to the revetment side during revetment construction, it is necessary to secure a place where the ruler can be installed. There are inconveniences such as having to drive the fixing piles 5, 5 of No. 1.

The present invention relates to a guide for rectangular walls with a simple structure that avoids the drawbacks of these conventional methods.The present invention is an arm that is slidably fixed to an H steel ruler that is fixed to the ground along the wall core in advance. Pile guide rollers are disposed opposite to each other at the leading end of the shaped guide body and at the intermediate portion opposite thereto, and the interval between the two pile guide rollers can be changed to a predetermined dimension as necessary.

An example of the implementation of the present invention will be described below with reference to FIGS. 4A and 4B. Reference numeral 6 denotes an H steel ruler fixed on the ground along the wall core in advance. An arm-shaped guide body 7 provided with slits 7a corresponding to the respective thicknesses of the upper surface projections of the ruler 6 is installed on the ruler 6. At this time, since the moving guide roller 8 is provided in the slit portion 7a, the guide body 7 can be easily moved along the wall core direction of the ruler 6. 9 is a fixed plate fixed to the guide body 7, 10 is a movable tightening plate, and the tightening handle 1
1, the guide body 7 is fastened to the ruler 6. The leading end of the guide body 7 is formed in a U-shape relative to the middle part, and pile guide rollers 12 are provided facing each other at the leading end and the middle part, and the interval between the two guide rollers 12 is square. An adjustment flange 13 is interposed in the middle of the guide body 7 to match the outer diameter of the wall pile 2. The wall pile 2 can be buried smoothly by the pile guide rollers 12. In some cases, the pile guide roller 12 at the tip may be provided on the removable bracket at the tip without intervening the adjustment flange 13, or one of the pile guide rollers 12 may be omitted. .

After burying the rectangular wall pile 2 in the states shown in FIGS. 4A and B, the tightening handle 11 is loosened and the guide body 7 is moved upwardly on the ruler 6 as shown in FIG. 4A. When the outer diameter of the pile 2 is reached, the handle 11 is tightened again and the same burying operation is repeated to construct the wall.

By using the rectangular wall guide of the present invention, the following effects can be obtained.

(1) Wall piles can be constructed using only one H steel for continuous direction rulers, simplifying the ruler.

(2) Since only one H steel is required, the complicated pre-work process can be omitted even when installing a stage on a conventional slope site or bank revetment construction.

(3) The device has become more compact and easier to transport.

(4) Wall piles can be buried smoothly due to the pile guide rollers.
