Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ground stabilizer embedded in a ground in which a hollow body having a connecting bar at an upper end portion and a leg portion at a lower end portion is filled with concrete to support a structure.
[0002]
[Prior art]
Conventionally, there is a ground stabilizer embedded in the ground, which has a connecting bar at the upper end and a leg at the lower end, and has a frame-shaped outer shape (see, for example, Patent Document 1).
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 11-21912 FIG. 7
[Problems to be solved by the invention]
By the way, in the above-mentioned conventional one, since the upper surface is a flat surface, there is no particular problem in the case of a vertical load, but when the structure is inclined or the load from the structure is an inclined load due to an earthquake or the like. In such a case, the stress distribution from the stabilizer to the ground may be disturbed, which may cause a bias in the ground support force and uneven settlement.
In addition, there is a problem that the individual block-type blocks are heavy and the manufacture thereof is not easy.
[0005]
The present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is to load the upper rod-shaped body by making the outer shape spherical or elliptical spherical. To prevent the stress distribution from the stabilizer to the ground from being disturbed and to prevent the bias of the ground bearing force and the uneven settlement from occurring, and the individual stabilizers are lightweight and corrosion resistant. It is intended to provide a ground stabilizer that has the same and is easy to manufacture.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the ground stabilizer according to the present invention is such that the structure is supported by filling concrete into a hollow body having a connecting bar at the upper end and a leg at the lower end. The hollow body is made of a synthetic resin and has a bowl-like body with legs formed at the lower end, and a bowl-like body made of synthetic resin and having a connecting bar inserted into the upper end. It is characterized by incorporating concrete in the hollow body.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
1 to 4 show an embodiment of a ground stabilizer according to the present invention, FIG. 1 is an explanatory sectional view of the ground stabilizer, FIG. 2 is a sectional view of the ground stabilizer, and FIG. 3 is a ground stabilizer. FIG. 4 is a cross-sectional view in which the ground stabilizer is installed in the manhole.
[0008]
In the figure, reference numeral 1 denotes a ground stabilizer, the ground stabilizer 1 is made of a synthetic resin and has a hollow bowl 3 formed with legs 2 at the lower end, and a synthetic resin made of synthetic resin 4 at the upper end. It is comprised with the hollow bowl-shaped body 6 in which the inlet_port | entrance 5 was formed.
[0009]
A connecting bar 8 for connecting the reinforcing bars 7, 7,... Is attached to the injection port 5 of the bowl-shaped body 6, and the upper circumferential surface of the bowl-shaped body 3 is disposed on the lower circumferential surface of the bowl-shaped body 6. A locking portion 10 is formed to be engaged with the locking portion 9.
[0010]
In the ground stabilizer 1 having the above-described configuration, first, the locking portion 9 of the hook-shaped body 3 and the locking portion 10 of the hook-shaped body 6 are locked to join both the hook-shaped bodies 3 and 6 together. Both ends of the connecting bar 8 assembled in a spherical shape and made of needles are inserted into the injection port 5 and installed at the upper end of the bowl 6.
And concrete 4 (lightweight concrete) is inject | poured in a spherical shape from the said injection port 5, and the concrete 4 is built in a hollow body. At that time, the connecting bar 8 protrudes from the upper end portion of the bowl-shaped body 6 and the concrete 4 is hardened so that the connecting bar 8 is firmly attached.
In this way, one ground stabilizer 1 that is lightweight, corrosion resistant, and easy to manufacture is completed. And many ground stabilizers 1, 1,... Can be assembled and manufactured by the same operation.
[0011]
Next, when setting the ground stabilizer 1 in the lower part of a structure such as a manhole, the ground stabilizers 1 are arranged vertically and horizontally (for example, 8 × 8 pieces), and the reinforcing bars 7 are arranged on the connecting bars 8. A large number of ground stabilizers 1, 1,... Can be formed into a substantially cushion-like shape by being fixed vertically and horizontally by welding or the like.
[0012]
Then, the ground stabilizer 1 made in the form of a cushion is placed at the lowermost part of the hole for installing the manhole so that the leg 2 is submerged in the ground 11 and the concrete 12 is placed on the upper surface of the ground stabilizer 1 made in the cushion form. The manhole bottom plate 13 is placed thereon.
By installing the ground cushion 1 in the form of a cushion, the load received by the upper saddle body is equalized, and the distribution of stress from the stabilizer to the ground is prevented from being disturbed. Prevent subsidence from occurring.
[0013]
In addition, although the ground stabilizer 1 uses the spherical thing in this Example, it is also possible to use an elliptical thing.
[0014]
【The invention's effect】
According to the ground stabilization tool of the present invention, by making the outer shape spherical or elliptical spherical, the load received by the upper bowl is equalized, and the distribution of stress from the stabilizer to the ground is disturbed. In addition to preventing the occurrence of uneven ground support and uneven settlement, the individual stabilizers are lightweight, corrosion resistant, and easy to manufacture.
