Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction method for forming a strong foundation on soft ground.

BACKGROUND ART Recently, land conditions around urban areas have worsened, and more and more architectural structures and civil engineering structures are being constructed even on soft ground.

Conventionally, when constructing houses, retaining walls, etc. on soft ground, the soft ground was generally improved by replacing it with good quality earth and sand, and then a chestnut stone foundation work 20 was applied as shown in Figure 1. After the foundation is built, either by pouring the foundation concrete 21, or as shown in Fig. 2, by driving the piles 30 into the soft ground, applying the chestnut stone foundation work 31, and then pouring the foundation concrete 32. The method used was to place a superstructure on top, but replacing the ground requires removing a large amount of defective soil and using the same volume of good quality soil, which requires a lot of labor and a lot of money. Not only is this uneconomical, but it also causes pollution from sludge on the surrounding land, making construction difficult.

In addition, in order to uniformly transfer the load of a structure from the foundation surface to the underlying ground, the ground must be prepared evenly, but in the case of ground improvement, this is difficult, and it is necessary to use chestnut stone foundations or cut-in foundations. With earth and sand foundations, the foundation lacks integrity and the load is not distributed evenly, which can lead to uneven settlement.On the other hand, with pile foundations, the load is generally borne only by the piles, so the load distribution is uniform. Therefore, it was a cause of uneven subsidence.

In view of the above-mentioned difficulties of the conventional technology, the present invention was made with the purpose of providing a construction method that can construct a strong foundation on soft ground. The ratio of height and height is 2=1, and the outer surface of each wing has a refracted wave shape with the same waveform and wave width, and the length of each wing is 2n phase on the width side and n phase on the height side. On the back surface of the top plate, which is formed so that the shapes of the opposing side surfaces can mesh with each other, a right triangular plate that intersects at right angles is protruded, and an antibody is provided to protrude from the lower part of the intersection, and each wing part and the center part A cross-shaped concrete basic block with a plurality of through holes vertically provided in the front, and a rectangular cylindrical body with a cylindrical through hole in the center, each outer side of which is similar to the basic block. The refracted wave shape has the same wavelength and the same wave width, and the length of each side is 2n phase, and the opposing side surfaces are formed so that they can mesh with each other, and the height is the same as the thickness of the top plate of the basic block. A wedge block formed by the sum of the lengths from the back side of the top plate to the lower part of the intersection of the right triangular plate is combined, the basic blocks are arranged in a grid pattern, and the antibody is driven into the ground. A wedge block is inserted into a space surrounded by four adjacent basic blocks to form an interlocking plate, and the through hole is filled with sand and gravel and compacted.

A right triangular plate body that intersects at right angles is provided on the back surface of the top plate, which is formed so that the sides are in 2n phase and the height side is in n phase, and the shapes of opposing side surfaces can mesh with each other, and project from the lower part of the intersection. A cross-shaped basic concrete block with a protruding antibody and multiple vertical holes in each wing and the center, and a rectangular cylindrical block with a square-shaped hole in the center. Each outer surface of the body is formed with a refracted wave shape having the same wavelength and same wave width as the basic block, and each side has a length of 2n phase, and the shapes of the opposing side surfaces can be meshed with each other. , and the height is determined by combining the thickness of the top plate of the basic block and the right-angled triangular plate protruding from the back surface of the top plate. Then, arrange the basic blocks in a grid pattern, drive the antibody into the ground, insert a wedge block into the space surrounded by the four adjacent basic blocks to form an interlocking plate, and fill the hole with sand and gravel. A foundation construction method characterized by filling and compacting. 2. The construction method according to claim 1, wherein the through holes in the basic block and the wedge block are narrowed upward. 3. Claim 1, in which a rectangular wedge block is meshed and connected and inserted into a rectangular notch formed on the four circumferences of the mating plate.
Section 2 or Section 2 [Act. 4. The construction method according to claim 1, 2, or 3, in which square wedge blocks are meshed and connected and inserted into square notches formed at the four corners of the mating plate.
