JPH1129927A - Ground subsidence preventive foundation pile using old tire block - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the ground subsidence, and to reinforce the ground by packing stones and crushed stones in a tire to form a foundation pile for a building or a fence, and installing the blocks which are stacked in layers according to the degree of softness of the ground as the foundation pile. SOLUTION: During work execution at site, the ground is dug by the width and the depth according to the size and the layered stack of old tires, and tires 1 are installed as foundation piles of a simple structure. When the foundation pile must be buried deep, the tires 1 are stacked in layers, the ground part 2 at the hole of the tire body on the bottom side is dug slightly deeper so as to form a leg 4. Stones and crushed stones 3 are packed in the hole part 2 to form a pile of a tire block, and the ground subsidence is prevented to form a ground subsidence preventive pile for a building or a structure. The size or the number of layers of the tire bodies 1 of the tire block are different depending on the weight of the building or the degree of softness of the ground. The piles in which concrete is placed in a shop as a product can be installed as the ground subsidence preventive pile.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a low to mid-rise building. For the subsidence of the foundation of structures and poles and the reinforcement of the roadbed, stones, crushing and concrete are put into the old tires, or a diamond block filled with concrete is installed at the foundation of buildings and structures, As a basic set for settlement prevention, four old tires are used to prevent settlement of the roadbed.
Laid as a single unit, stuffed stones and crushed stones into tires,
This is a land subsidence prevention method that uses old tires to strengthen the ground and prevent land subsidence by filling rows and crushed stones into the center space as a tire block. In the case of casting on site,
Building structures. As a base for poles, etc., calculate the size and thickness of old tires according to the softness of the ground, lay the tires, lay stones, crushed stones and ready-mixed concrete, and use them as tire blocks by inserting or packing them By doing so, prevention of land subsidence can be strengthened. According to the conventional method of preventing land subsidence, concrete pillar piles are cast on buildings and structures, so that excessive construction costs are required for low and middle-rise buildings and structures. Formwork must also be made on small foundations and foundations. Therefore, the present invention relates to a method for strengthening the ground which also serves as a foundation pile for preventing ground subsidence by old tires, and is also a method of recycling and using old tires. When driving directly at the site, calculate the size of old tires and the number of layers by stacking using the calculation formula, dig a hole in the foundation part of the building or structure by the depth of the size of the tire and the number of layering, Drill further down the center. When the excavation work is completed, install the tire in the hole. Depending on the situation at the site, the material to be loaded from the top can be stone, crushed stone or concrete. At this time, stones, crushed stones, or concrete are also filled in the holes dug by lowering the center by one step. As a result, it becomes a foundation pile that strengthens the ground and prevents settlement of the ground. In the case of product delivery, old tire blocks filled with concrete in old tires at the factory, tire blocks in several layers in holes dug at the site,
The installation is completed only by installing. In the case of reinforcement of the roadbed, etc., four old tires are regarded as one unit on a plane,
Tires are laid and stones or crushed sand are stuffed from above, and a space is created in the center part where two and two are laid in parallel, so stones and crushed sand are also stuffed into that space,
When the wedge works, the stones or crushed stones packed into the space by the earth pressure from the outer periphery act as a wedge, so that the four tire blocks are the same as those connected.
From now on, two tire blocks will be laid vertically or horizontally to make room. The space is filled with stones and crushed stones.
By tying the tire blocks vertically and horizontally to fill the inside of the tire and the space, the tire blocks laid all over are knitted together and act more strongly to strengthen the roadbed. This is a roadbed reinforcement method to prevent settlement.

Embodiments will be described below with reference to the accompanying drawings. When the site is constructed as a foundation pile for a simple structure, the tire shown in FIG. 1 is laid down by the width and depth according to the size and layering of the old tire. When deep foundation piles are required, tires are stacked to form a layer as shown in FIG. At this time, the portion of the hole in FIG. 2 of the tire on the bottom surface is dug a little deeper and laid so that the foot becomes as shown in FIG. When stones, crushed stones or concrete are packed into this as shown in FIG. 3, a tire block pile as shown in FIG. 3 is completed. Also, as a pile for preventing the settlement of the roadbed and as a pile for preventing settlement of the building or the structure, the size of one tire tire as shown in FIG. 2 and the number of layers are different depending on the weight of the building and the softness of the ground. When stacking, piles are used as a single pile as shown in Fig. 3, so that piles with concrete installed at the factory can be made into complete piles as soil subsidence prevention piles. It is only necessary to dig down the place to be laid according to the tire block and to install the tire block of FIG. 3 in the hole. In addition, since it is rubber, it can absorb the impact of external pressure and has a large friction coefficient, so it is effective as a pile for preventing subsidence. Further, in the case of a land subsidence such as a road, the tire of FIG. 1 is laid as shown in FIG. 4, and stones or crushed stones as shown in FIG. 3 are packed in the holes of the tire of FIG. In between, as shown in FIG. 4, the stones and crushed stones shown in FIG. 3 are stuffed to act as a wedge. At this time, it is a block construction method using old tires that can absorb the external pressure from the horizontal weight and so on because it is a rubber tire.

[Brief description of the drawings]

FIG. 1 is a perspective view of a tire.

FIG. 2 is a perspective view of a tire block in which a stone or crushed stone is packed in a tire.

FIG. 3 is a perspective view of a tire block in which concrete is packed in holes in which tires are stacked and stacked.

FIG. 4 is a plan view when a stone or crushed stone is packed and laid in a tire.

[Explanation of reference numerals] The reference numeral 1 indicates a tire main body. Reference numeral 2 is a hole portion of the tire body. The sign of 3 is stone, crushed stone or concrete. The portion indicated by reference numeral 4 is a portion of a stone, crushed stone, or concrete foot that extends below the bottom of the tire.

Claims (1)

[Claims] Claims: 1. A tire block in which stone, crushed stone, ready-mixed concrete, or the like is put or packed in a tire so as to be a foundation pile of a structure, a building, a hay, a pole, or the like. Large size tires Small size tires and two-layered stack. By installing the tire blocks with three layers and one layer as one foundation pile,
Prevent subsidence and strengthen the ground. In addition, stone, crushed stone, concrete, or the like is provided at the lower part of the tire, and by attaching one foot, it is possible to further strengthen the foundation pile. The ground softness W is used as a guide for the number, size, and layering of tires used for ground reinforcement. Weight of building construction t Prevention coefficient of ground subsidence of old tires G Large number of tires stacked [Claim 2] In order to prevent the subsidence of the roadbed, two tires are laid side-by-side on the horizontal and four tires, and a tire block filled with stones, crushed stones, etc. is regarded as one and one unit. There is space in the part. When stones, crushed stones and the like are packed in this space, the four tire blocks are connected by the action of a wedge to prevent subsidence of the roadbed.
