detailed information
Pulau Tekong, the second largest outer island in Singapore, is a military reserve, which is a land area of 4901522 ㎡ formed by reclamation. The reclamation project builds seawalls outside the coastline, encloses the sections that need to be reclaimed, and then fills the sea with soft soil and sand, so that the height of the reclamation section is basically equal to the seawalls outside the coastline. Large area land reclamation is one of the effective ways to solve the increasing scarcity of land resources in coastal cities. To ensure the consolidation of the land surface through land reclamation, soft foundation treatment is required.
Construction methods
After the design and demonstration of the Shengzhou Foundation team, a soft foundation treatment plan was determined. The Shengzhou Foundation's non drainage sand cushion vacuum preloading method (patent number: 2007100312215) did not require a sand cushion, and the vacuum preloading was directly transmitted to the deep soil foundation through a specially designed connection (patent number: ZL 2009 2 0046917.7) and vacuum pipe network and long and short drainage boards, reducing the loss of vacuum efficiency along the drainage board due to viscous resistance, and improving the effectiveness of soft foundation treatment, It saves resources, protects the environment, effectively shortens the construction period, and has profound engineering practical significance. During the vacuum preloading process, vacuuming the shallow surface layer and then the deep and shallow layers not only ensures the vacuum pumping effect of the deep soft soil foundation, but also accelerates the vacuum preloading speed of the deep soft soil foundation. Its design is exquisite and the operation is simple.


economic performance
Guangzhou Shengzhou Foundation Engineering Co., Ltd. is a high-tech enterprise that integrates scientific research, design, and construction. It has been a soft foundation treatment brand for 20 years and has multiple subsidiaries in coastal areas, Hong Kong, Macao, and Southeast Asia. It is a leading domestic construction unit for soft foundation treatment projects. The patented technology "NS vacuum preloading method" developed by the company has the advantages of short construction period (saving 30%), low cost (saving 30%), safety and environmental protection (no damage or emissions) in soft foundation treatment, We are committed to providing comprehensive solutions for soft foundation treatment construction such as sea reclamation, port and dock construction, airport bridges, and municipal construction.
One fast: 30% reduction in construction period, Shengzhou's unique global leader
Traditional soft foundation treatment methods such as preloading and vacuum preloading have become mature and reliable, but there are problems with slow construction, high cost, and environmental protection. Shengzhou innovates and upgrades traditional construction methods in practice, taking the lead in launching the globally unique patented technology for soft foundation treatment - NS vacuum preloading method, which has received high praise from the industry.
Two provinces: 30% cost savings, comprehensive technology upgrade
NS vacuum preloading method is a revolutionary upgrade of traditional vacuum method, with an effective processing depth of up to 40 meters and more reliable quality. No need for drainage hourglass, cost savings of 30%, stronger drainage system, fast construction speed, and 30% reduction in construction period
Three environmental protection: non-destructive and emission free, with a wide range of applications and green environmental protection
The NS vacuum preloading method is suitable for vast areas with complex geological conditions, especially for the reinforcement effect of soft soil. The construction process has no construction waste, does not damage the geological structure, does not affect the surrounding environment, is green and environmentally friendly, and has significant advantages.
