Abstract

PURPOSE:To surely prevent the subsidence of a foundation by contacting a stabilizing plate consisting of reinforcing edges and a through hole for the foundation with the coupling plate of the foundation. CONSTITUTION:A hole 11 is excavated, and a stabilizing plate 5 consisting of reinforcing edges 6 and a through hole 7 for a foundation A is set on the bottom of the hole 11 and uniformly struck to cause the plate 5 to closely contact with the bottom of the hole 11. The connecting groove 9 of a drive bar 8 is coupled with the portion to be struck of the foundation A, and the drive bar 8 is struck to drive the foundation A through the through hole 7 of the plate 5 into the ground while housing soil into the foundation A. At the same time as the coupling plate 4 of the foundation A contacts with the plate 5, the collar 10 of the drive bar 8 also comes into contact with the bottom of the hole 11. The drive bar 8 is then pulled out, a pole is erected on the foundation A set under the ground, and the hole 11 is refilled with soil.

Description

[Detailed Description of the Invention] The present invention increases the amount of IJ-installed gourds in a driving force type steel ball foundation to strengthen the lateral pressure resistance and can sufficiently cope with the fall of the established ball. On the other hand, Yanagi cannot hide his anxiety about the subsidence.

The present invention provides a reliable countermeasure against such a situation by engaging a stabilizer plate having a sufficient resistance area with the base body during the casting process of the base body for the ball. The present invention will be described in detail below with reference to the accompanying drawings.

With the 1st front view, 2nd side view, and 3rd national affairs map (
11 is a resistance plate, and the resistance plate fil is a rectangular steel plate, with a semicircular cross section in one longitudinal direction, and both sides of the plate are straight and connected as shown in (2). To illustrate the height m, the semicircular surface is bent into a straight line parallel to both connecting sleeves (2) to form the attacking part (3), and on the semicircular outer peripheral surface of the lower part of the planned amount from the upper side. The locking plate (4) is fixed, and two of the above resistance plates (1) are prepared and combined to form a perfect circular cross section, and the joining sleeve (2) that brings people into close contact is fixed. Integrated-C basic body (A)
That is.

Next, the m4 diagram shows that the cross-section of the foundation (A) is opened in the center of the rectangular plate having a planar area equal to the required subsidence strength, and a foundation passage hole (7 )
In addition, it shows a stabilizer plate (5) whose opposite sides are bent into an upright shape to serve as a reinforcing edge (6),
Also, Figure 5 shows the driving tool used for pouring the foundation (A), which engages the coupling groove (9) at the tip with the striking part (3) of the foundation (A). In this state, the rear end is the basic body (
A driving rod (8) with a length that protrudes the required amount from the upper side of Δ)
A flange (10) with a diameter that allows a person to pass loosely through the base body (A) is fixed to a portion that coincides with the locking plate (4).

Below, the construction state of the claimed invention will be explained first.
As shown in the figure, the construction ground is made slightly deeper than the height from the fixed part of the locking plate (4) of the foundation (Δ) to the upper side, and
) was drilled to allow the flat surface of the hole (11) to be placed on the bottom surface, the stabilizer plate (5) was placed on the bottom surface of the hole (II), and the flat surface of the stabilizer plate (5) was tapped evenly. The bottom surface of the hole and the flat plate surface are brought into close contact, and then the connecting groove (9) is engaged with the attacking part (3), and the base body (A) integrated with the driving rod (8) is inserted into the base body through hole. (7), and while attacking with the driving rod (8), the foundation body (A) is placed into the ground while storing the opposing soil in its own body, and finally, as shown in Figure M7. Driving ends when the locking plate (4) collides with the stabilizing plate (5) and no further driving is possible; The collar (10) also comes into contact with the bottom of the hole.

In this way, the driving rod (8) was removed and the remaining removal cavity was appropriately backfilled and the ball (+2) 4 base bodies (
Pass the ball inside A> and stick it on the bottom of the hole to make a layer of balls (12
) is maintained in a vertically erected state, and the rapid hardening cement is blended so as to start setting at most 1 minute after being mixed with water in the gap between the ball (12) and the base body (A). The solution is injected and filled, and the ball (12) is made to solidify and harden while checking the vertical state. Over time, it becomes a concrete body (13) with the same hardness as ordinary concrete, so it is placed underground. In this case, the ball (12
) will be firmly integrated and established vertically with the concrete body (13).

The gap between the excavated hole (11) and the foundation (A) is not backfilled with excavated soil, but in cases where even higher strength is required, this can also be hardened as a concrete body (13). This is a +i principle that will be even more effective if you learn it.
