Drainage Consolidation
Drainage Consolidation
Land soil improvement
The land reclamation forms a soft foundation. The surface of the site is dredger fill. The soft foundation and ultra soft foundation of muddy clay have high water content, high compressibility, large void ratio, and low bearing capacity, which cannot meet the requirements of future project construction. In order to effectively solve the problems of soft foundation construction and maintenance, new technologies such as plastic drainage plate combined with vacuum preloading, surcharge preloading, and vacuum combined with surcharge preloading are used to accelerate drainage and consolidation, It has good drainage effect, high efficiency, low construction cost, no noise, and no pollution, and is a mature and effective method for (ultra) soft foundation reinforcement treatment. It is widely used in the construction of airports, ports, docks, storage yards, and logistics industrial parks.
Construction Technique
Prefabricated Vertical Drains (PVD) Installation
Prefabricated Vertical Drains (PVD) Installation
Prefabricated Vertical Drains (PVD),also known as Wick drains are prefabricated geotextile filter-wrapped plastic strips with molded channels. These act as drainage paths to take pore water out of soft compressible soil so it consolidates faster.

Vacuum Consolidation
Vacuum Consolidation (or vacuum preloading) is a soft soil ground improvement method that is typically combined with Prefabricated Vertical Drains and Horizontal Drains (PVD+VCM) and basically is a solution to replace the use of a surcharge.

Soil Pre-Compression
Soil Pre-compression is one of the ground improvement technique which compresses the ground under an applied pressure before placing or completing the structural load. By the use of vertical sand drains the consolidation process can be increased which reduces the time of pre loading.

Water vapor separation vacuum preloading
The water vapor separation vacuum preloading technology is a patented soft foundation treatment technology independently developed by Shengzhou Company. By studying and improving the key technologies and construction equipment in the traditional vacuum preloading method construction process, the vacuum preloading construction process for large-area soft foundation treatment is improved.

Sandless pressurized vacuum preloading
Sandless pressurized vacuum preloading
The sand free boosting vacuum preloading process is based on ordinary vacuum preloading, by inserting anti clogging plastic drainage plates into the pre-treatment foundation, The vacuum branch pipeline is connected to the corresponding vacuum main pipeline through a variable diameter four-way joint, forming a vacuum pipeline network under the membrane. The booster pipe is inserted at the designated position. Apply horizontal pressure to the soil through the booster pipe, causing the pore water to move towards the drainage plate, further improving the consolidation degree of the soil.

Combined vacuum and surcharge preloading method
Vacuum combined surcharge preloading is the superposition of vacuum preloading and surcharge preloading. The vacuum combined surcharge preloading foundation treatment method is a new type of foundation treatment that combines plastic drainage board vacuum preloading method and surcharge preloading method.

NS vacuum preloading technology
The vacuum preloading method with no drainage sand cushion, patented technology from Shengzhou, is industry-leading. In practice, traditional construction methods have been improved, innovated, and upgraded, resulting in better drainage effect, reliable quality, no need for drainage sand cushion, cost savings of 30%, strong drainage system, shortened construction period by 30%, no damage to the formation, no impact on the surrounding environment, no damage, no emissions, and green environmental protection.
Anti clogging pressurized vacuum technology
The anti clogging plastic drainage board has good integrity and high resistance strength, effectively overcoming the clogging caused by sediment passing through the filter membrane. An energy-saving vacuum pump is used to connect the water and gas separation tank instead of a jet vacuum pump. Through microporous pressurization technology, it further promotes the directional movement of soil pore water, accelerates soil drainage and consolidation, has good quality and effect, advanced construction technology, shortens the construction period, environmental protection and energy conservation, and reduces costs.
