Gravel Base Construction Scheme

1. Preparation before construction

Determine the construction scope and clean up debris and weeds in the construction area. According to the design requirements, conduct survey and measurement of the foundation to determine the thickness and type of gravel. At the same time, prepare the mechanical equipment and materials required for construction, such as excavators, graders, gravel, cement, etc.

2.Selection and transportation of gravel

According to the design requirements and the nature of the project, select the appropriate type and specification of gravel. Commonly used gravels include limestone, granite, etc. The size of the gravel should be less than 40mm. During transportation, care should be taken to prevent impurities, soil, etc. from mixing into the gravel to ensure construction quality.

3. Foundation treatment

Carry out necessary treatment on the foundation according to design requirements. First, clean up the debris and floating soil on the surface to ensure that the foundation is clean and tidy. Then, the foundation is compacted using equipment such as vibratory rollers. Ensure the bearing capacity and stability of the foundation.

4. Laying of gravel base

First lay a layer of bottom gravel with a thickness of 15cm on the foundation, and then use a vibrator or flatbed machine for preliminary compaction. Then lay an upper layer of gravel with a thickness of 10cm and compact it in the same way. During the process of laying gravel, the uniformity and compactness of the gravel should be maintained.

5. Construction of isolation layer

1) Isolation layer material selection: Select appropriate isolation layer materials according to project requirements, such as polyethylene membrane or waterproof geotextile membrane

2)Isolation layer laying: The selected isolation layer material is laid on the gravel filling layer, which must be smooth and free of wrinkles and damage.

3) Isolation layer connection: The joints of the isolation layer should be sealed to ensure waterproof effect.

The above is the complete process flow of sand and gravel foundation construction. By strictly executing the above steps, the quality and safety of the construction can be ensured. During the construction process, special attention should be paid to environmental protection and safety measures to ensure the sustainability and social responsibility of the construction.

In conclusion, a gravel base construction scheme is an excellent choice for various construction projects. Its ability to provide stability, drainage, and cost savings makes it a preferred option for builders. By investing in a solid gravel base, you can ensure the success and longevity of your construction endeavors.
