Innovation Solution
A construction method utilizing basement space creation by installing dikes, crisscross enclosures, and seawater pumping to form land without hydraulic fill, allowing for simultaneous underground space development and reduced costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If rock and soil backfilling is used for land reclamation, then land can be formed, but extensive mineral deposits are required and natural ecological environment is destroyed
Solution Approach 1:
The invention extracts and removes the harmful element of mineral deposit backfilling from the reclamation process. Instead of bringing in rock and soil from mountains, the method uses in-situ seawater pumping and drainage to form land directly from the sea bottom, eliminating the need for external material imports and associated ecological damage.
Solution Approach 2:
The invention converts the harmful effect of seawater presence into a beneficial process. By pumping and draining seawater systematically, the method transforms the sea bottom into usable land while simultaneously creating underground basement spaces, turning what was previously an obstacle into a constructive development opportunity.
2Quantity of substance
If hydraulic fill plus vacuum preloading drainage consolidation is used, then the issue of large amount of mineral deposits is resolved, but marine ecological environment is destroyed and settlement time is extended
Solution Approach 1:
The invention completely extracts and eliminates the hydraulic fill process from the reclamation methodology. By using direct seawater pumping and drainage consolidation, the method removes the need for dredging and transporting large quantities of marine sediment, thereby protecting the marine ecological environment from further damage.
3Area of stationary object
If traditional land reclamation methods are used, then land area is increased, but construction cost is high and underground space is not utilized
Solution Approach 1:
The invention merges two previously separate functions into a single integrated process: land reclamation and underground basement construction. By combining seawater pumping, drainage consolidation, and basement formation into one unified methodology, the method achieves both surface land creation and subspace utilization simultaneously, eliminating redundant construction steps and reducing overall costs.
Solution Approach 2:
The reclamation process becomes multi-functional, serving both as a land formation method and an underground space creation technique. The pumped seawater and drained area serve dual purposes: forming the reclaimed land surface while simultaneously creating the void space needed for cost-effective basement construction.
4Quantity of substance
If natural impelling siltation is used, then no mineral deposits are required, but impelling siltation time is too long to meet rapid demand
Solution Approach 1:
The invention performs preliminary consolidation action through systematic vacuum preloading drainage before final land formation. By pre-consolidating the sea bottom soil through drainage consolidation, the method accelerates the settlement process and creates stable land faster than natural siltation, meeting rapid development demands without requiring extensive mineral deposits.

AI summary
A construction method of reclaiming land from the sea based on the basement utilization, which implementation steps are as follows: a. installing a dike along the coastline, enclosing a central reclamation area by the dike and the coastline; b. installing crisscross enclosures in the central reclamation area, dividing the central reclamation area into a mesh area by the enclosure and the dike; c, pumping drainage of seawater in a block area in the mesh area, forming land in the block area; d. constructing the enclosure in the mesh reclamation area, using the enclosure and subsidiary roads to form road arteriality; the block area being lower than the height of the enclosure, constituting a grid-like high-road/low-land land supply mode; e. developing the block area into an underground space area.
