Abstract

PROBLEM TO BE SOLVED: To visually check what kinds of troubles occur in future if the ground is not reinforced, by using a rigid material to constitute a base ground of a simulating device and then disposing a surface ground of a soft rigid resin which can be deformed on the base ground. SOLUTION: The base ground (B) consists of a rigid material which does not deform itself and has three parts of a shallow base ground B1, a slope ground B2 and a deep ground B3. Then a surface layer ground (A) consisting of a rigid resin material which can be deformed is placed on the base ground (B). The surface layer ground (A) is made of a rather hard sponge or the like and consists of a soft ground A1 for the slope, a soft ground A2 for flat ground and a hard ground A3 for flat ground. The sponge material for the surface ground (A) which is rather hard is not a normal sponge but a specified porous material that after a house model H is mounted on the ground, its surface is gradually pressed and deformed to sink with time. Thus, the ground state can be represented.

The residential ground effect experience device of the present invention is arranged at an exhibition site or a business negotiation place of a house construction company.
Then, by obtaining information about the site owned by the owner who is going to build the house and listening to the address and address of this site, the city planning map or a void map held by each local government. The impact of the residential ground of the present invention is estimated by estimating the ground condition of the site from the past damage area map, landslide occurrence location display map, steep slope collapse danger area map, legally designated danger area map, etc. The experience device informs that it is necessary to perform appropriate ground reinforcement work.

With reference to FIGS. 1, 2, and 3, description will be given of the overall configuration of the residential ground effect experience device. The supporting ground B is made of a rigid material. Then, the supporting ground B itself does not deform. The supporting ground B is composed of a shallow supporting ground B1, an inclined supporting ground B2, and a deep supporting ground B3. Then, on the support ground B, the surface ground A formed of a deformable rigid resin material
Is configured to be placed. The surface ground A is formed of a slightly hardened sponge material, etc., and has a soft ground A1 for sloping ground, a soft ground A2 for flat ground, and a hard ground A for flat ground.
It is composed of 3. The slightly hardened sponge material that forms the surface ground A is not a porous material that is immediately pushed in as soon as the housing model H is placed, like a normal sponge material, but after the housing model H is placed,
It is made of a unique porous material whose surface is gradually pushed and deformed and subsided with the passage of time so that the ground condition can be expressed.

As described above, the surface ground A formed of the porous material gradually deforms, so that the ground gradually changes with the lapse of years after the construction of the house, and the house is inclined. It is configured to be able to observe. In addition, on the support ground B, the surface improved ground D
It is configured to be able to represent the portion of and the portion of the surface ground A that has not been improved. In the portion of the surface layer improved ground D, it is possible to express that the soil layer improving material is injected to solidify the surface layer ground A to improve the bearing capacity of the ground, and when no improvement is made. than,
It has a large bearing capacity, and it is configured so that it can be seen that there is little occurrence of subsidence of the ground and inclination of the house.

The housing model H shown in FIG. 2 is composed of a weight such as lead, and the surface ground A is likely to be deformed,
This is configured so that it can be easily observed. In addition, the bottom surface of the housing model H is not a flat surface, and projections corresponding to the foundation are projected at the four corners, and the weight of the housing model H is received by the projections.
Has a large supporting weight per area, and has a structure in which deformation easily occurs. Also, by using four protrusions, as shown in FIG. 10, it is configured so that it is easy to understand that the inclined state of the house model H is differently generated due to the difference in the ground supporting force of each corresponding portion. .

Further, as shown in FIG. 3, a basic model K of the basic part of the house is also prepared. By placing this basic model K on the surface ground A, the difference in the bearing capacity of the ground can be obtained. It is structured so that it can be understood.

FIG. 4 shows a state in which the foundation pile C is driven into the inclined support ground B2 of the influence experience device for a residential ground. When the ground reinforcement work is not performed on the inclined support ground B2, the effect of the support ground B is directly exerted, so that the model house H gradually becomes inclined. Since the weight of the house model H is transferred to and supported by the support ground B by the foundation piles C by driving from the bottom of the foundation to the length of the support ground B, the ground subsidence does not occur. The state in which the ground subsidence does not occur is illustrated in FIGS. 5 and 6.

FIGS. 7 and 8 show another embodiment of the effect experience device for the residential ground where the structure of the support ground B is different. In this case, the inclined support ground B2 is formed in two places, and the deep support ground B3 is formed like a valley. It is possible to express the occurrence of the situation of a drowning valley in which a house inclines toward this deep portion of the support substrate B3. In order to reinforce the ground at the portion of the drowning, the foundation pile C is driven in, and the portion of the surface layer improved ground D is arranged above the deep support substrate B3,
With these configurations, it can be understood that the inclination and the subsidence of the house model H are prevented.

FIG. 9 shows how the basic model K sinks and inclines due to the difference in the supporting ground B. Further, FIG. 10 illustrates how the house model H sinks and inclines due to the difference in the supporting ground B. In the case of the surface improved ground D, ground subsidence does not occur. In the case of shallow support ground B1 without surface improvement, equal subsidence occurs. Further, in the case of the supporting ground B2 in which the supporting ground B is inclined, a differential settlement state occurs, which is a very dangerous situation. It can be seen that it is necessary to drive the foundation pile C in the sloping support ground B2 in which the differential settlement occurs.

[0016]

As described above, the present invention has the following advantages. As described in claim 1, the surface ground A made of a deformable soft rigid resin or the like is arranged on the support ground B made of a rigid material, and the support ground B is provided.
Is composed of a shallow support ground B1, an inclined support ground B2, and a deep support ground B3, and the housing model H composed of weights is placed on the surface of the surface ground A. The difference between the above makes it possible to see visually how the house built on the surface ground A will be affected in the future, and what kind of ground reinforcement work will be performed so that no problems will occur in the future. It will be possible to know if you need to.

Since the foundation pile C is driven into the shallow support ground B1 and the inclined support ground B2 as described in claim 2, it is possible to clearly know the effect of the reinforcement by the foundation pile C, and the house When constructing a building, foundation piles can be driven in with the consent of the contractor and the construction company, and a sufficient ground reinforcement effect can be obtained.

Since the surface improved ground D is formed in a part of the surface ground A as described in claim 3, the effect of the surface improved ground D can be known, and the effect is not as great as the reinforcement by the foundation pile C. However, if the surface improvement ground D was reinforced during the construction of a house, it became possible to replace the foundation piles with the surface improvement ground in areas where sufficient ground bearing capacity could be obtained.
