How to square the foundation, the easiest way to square the foundation

Prepare the materials:

1. Construction drawings.

2. Cement. 3. Rebar.

4. Bricks. 5. The rest of the required building materials.

How it works:

1. Choose a ground with uniform soil

The uniform soil quality means that the soil quality below should also be uniform, keep the force balanced, and do not choose a place that is soft and one side. It will cause uneven settlement of the foundation, which is the worst, worse than the texture of all soft soil.

Second, the treatment of bad foundations

The bottom surface should not be made according to the original slope, but should be made into a step shape. If the mountain range itself has a slope, the deep place must be dug to the bottom of the stone, and the structure of the upper house should be selected as a pillar structure, and the stressed column foundation should go straight to the bottom of the stone.

3. Treatment of soft and hard foundations

The principle of equal pressure strength is used to increase the area of the foundation at the soft foundation. Strengthen the ground beams of the foundation part.

Stiffness; Strengthen the overall stiffness of the house (at this time, the house can not be built in the open space, the height of the house should not be too high, the wall spacing can be denser, do not open the doors and windows, such as the original is not a frame structure.

can be upgraded to a frame structure and other techniques to deal with).

Fourth, use different methods to deal with the foundation according to local conditions

Sometimes it will encounter a part of the weak soil foundation, which cannot meet the needs of the foundation bearing capacity.

It is necessary to ask for professional design, unit design pile foundation or foundation treatment.

Fifth, according to the situation of the pit, the specific development of the foundation plan

When there is a large pit, you can use the method of erecting a ground beam to cross or make a foundation from the bottom of the large pit, which one to choose, but also depends on the size of the pit and other comprehensive considerations.

Sixth, first remove the miscellaneous soil and then make the foundation

There is a general principle to grasp in foundation treatment, that is, to remove all the floating soil and soft soil on the surface of the ground.

1. How to measure:

You can use a long tape measure to pull the diagonal line to see if it is equal, measure 6 meters on one side at a certain corner and make a mark, measure 10 meters on the other side and make a mark, measure the distance between the two marks to see if it is 10 meters, according to the Pythagorean theorem; It is also possible to use a theodolite total station.

Second, a brief introduction to the foundation:

Foundation refers to the soil or rock mass that supports the foundation underneath the building. The soil layer that serves as the foundation of a building is divided into rock, gravel soil, sand, silt, clayey soil and artificial fill. There are two types of foundations: natural foundations and artificial foundations.

A natural foundation is a natural layer of soil that does not need to be reinforced by man. Artificial foundations need to be reinforced, and there are stone chip cushions, sand cushions, mixed ash backfill and then tamping, etc.

1. The strip foundation is the most common and most suitable one in the construction of rural self-built houses, and the length of the foundation is much greater than the width, and the length of the foundation is more than 10 times that of the foundation, and it is mostly used for single-layer or multi-layer masonry structure. Self-built houses are generally mainly brick-concrete structures, brick-concrete structure houses mainly rely on the brick wall to bear the load, and the load of the roof panel and the floor panel and the plate load are transmitted from the wall to the wall, and then from the foundation to the foundation, that is to say, the brick-concrete structure house is the most in line with the actual stress of the house. 2. The lattice foundation is actually a derivative of the strip foundation, which is made of the cross in the horizontal and vertical directions, and its bearing capacity is stronger than that of the strip foundation, which is commonly found in rural self-built houses with higher floors.

3. Independent foundation is also a more common form of foundation in rural self-built houses, and the construction of many foundation foundations is the simplest, with good overall performance and strong resistance to uneven settlement. As long as the geological requirements allow, reinforced concrete, plain concrete, etc. are generally used, and the building materials used are relatively common and cost-effective. 4. Rubble foundationRubble Qing file foundation is the foundation of masonry after rough processing of natural stone, and it is often used to build houses in mountainous areas.

Generally, small foundations are manually placed with tape measures.
