Learn more so you can choose the lift and level solution that suits your needs to make your production environment safer and more efficient.

First, the production workshop foundation settlement reinforcement and lifting harm

1, affect the normal operation and accuracy of the equipment

① Levelness and verticality of the device: foundation settlement reinforcement and lifting will change the levelness and verticality of the device installed on the ground, which affects the normal operation of the device.

(2) Loose connecting parts of the equipment: subsidence may loosen the connecting parts of the equipment, aggravate wear, and increase the frequency of failure.

(3) Precision reduction of high-precision equipment: for high-precision equipment, foundation settlement reinforcement and lifting may lead to reduced accuracy and normal work, thus affecting product quality.

2, reduce production efficiency

Disruption of production rhythm, production interruption or deceleration: the settling ground will disrupt the original production rhythm, may lead to production interruption or deceleration, directly affect production efficiency, and need to spend more time and energy to deal with the problem of uneven ground.

3. Threaten personnel safety

Increase the risk of falls or industrial accidents: In areas where people frequently walk or operate, the uneven ground is easy to make workers lose their balance when walking or operating equipment, increasing the probability of accidents such as falls and falls.

4. Affect warehousing and logistics

Damage to goods or increased difficulty in transportation: Uneven ground will increase the difficulty and risk of cargo transportation, reducing transportation efficiency. foundation settlement reinforcement and lifting may cause shelves to tilt, goods to collapse, resulting in property damage.

5, threatening the safety of plant building structure

Structural cracks and deformation increase the risk of plant collapse: long-term settlement may lead to cracks and deformation of walls, columns and other structures of the plant, affecting the carrying capacity of the building. When the uneven settlement of the foundation is serious, it may lead to the collapse of the plant, resulting in a major safety accident.

6. Increase business operating costs

Increased repair and maintenance costs, decreased market competitiveness: In order to ensure the normal progress of production, enterprises need to frequently repair and maintain the settled ground, which will undoubtedly increase the operating costs of enterprises. Customers and visitors may question the production environment of the enterprise, which will affect the market competitiveness of the enterprise.

7. Limit plant layout and equipment update

Limited layout adjustment: the original suitable layout may no longer be applicable due to changes in the ground, limiting the layout adjustment of the plant.

(2) The installation of new equipment is affected: the foundation settlement reinforcement and lifting may affect the installation of new equipment and the introduction of new processes, and hinder the technological upgrading and capacity expansion of enterprises.

Ii. foundation settlement reinforcement and lifting solutions

1. Non-destructive and controllable soil solidification technology

Hengxiang Hongye uses special new composite materials to transform the foundation soil layer, adopts the micro-invasive technology of 10-30mm small holes, 1-90s to quickly consolidate the foundation soil to form a new structure with high strength and anti-seepage water. In the process of soil filling and compaction, upward lift will be generated, which will promote the ground of the production workshop to lift, improve the foundation bearing capacity, and treat the foundation deformation problem from the root. Prevent secondary settlement and provide a 20-year warranty.

Scope of application: It is widely used all over the country, and has good consolidation effect on silt soil and collapsible loess. The technology is simple in construction, does not need large-scale excavation or reconstruction, does not need to stop production, does not affect production and operation, short construction period, safety and environmental protection, and reduces the difficulty and cost of construction.

2. Pile foundation reinforcement

Pile foundation reinforcement is a kind of reinforcement method to transfer the upper load to the deep stable soil layer by driving precast pile or cast-in-place pile into the settlement area. According to the foundation conditions and the load requirements of the production workshop, different types of piles (such as steel pipe piles, concrete piles, etc.) can be selected, and the site conditions are required, which may interrupt production.

Scope of application: pile foundation reinforcement can significantly improve the bearing capacity of the foundation, but the excavation works are too large, the cost is high, the construction period is long, and it is only suitable for the area with serious settlement.

3, traditional grouting reinforcement

Traditional grouting reinforcement is to fill the soil void by injecting slurry materials such as cement slurry into the foundation, transform the internal mechanical structure, and prevent leakage and blockage. It only plays a strengthening role, and can not raise and level the ground.

Scope of application: Suitable for uneven settlement of foundation, cracks and other problems, the use of materials for cement slurry, not environmentally friendly, in the treatment of silt, silt, clay and other soft soil foundation, poor drainage, long solidification time, late easy secondary settlement. The choice of traditional grouting materials should be determined according to the permeability, settlement degree and construction conditions of the foundation.

4. Soil change cushion method

The original soft soil is dug out and replaced with materials of high strength, low compressibility and non-erosive.

Scope of application: Only applicable to the treatment of shallow soft foundation and uneven foundation.

Third, precautions

When selecting the lifting and leveling scheme, the following factors need to be considered:

1, settlement degree: according to the severity of settlement to choose the appropriate reinforcement method.

2, foundation conditions: understand the soil quality, bearing capacity, permeability and other characteristics of the foundation, in order to choose the appropriate reinforcement materials and processes. The non-destructive and controllable soil solidification technology is suitable for complex geological conditions such as bedrock undulation, uneven local soil quality, large thickness of lying soft soil, existence of hidden trenches and caverns, and excessive water content of foundation.

3, construction conditions: consider the environment of the construction site, space restrictions, construction period and other factors, choose the appropriate reinforcement scheme.

4, economy: under the premise of ensuring the reinforcement effect, choose a low cost reinforcement scheme.
