Title:
SWIRL POOL CONSTRUCTION METHOD EMPLOYING SEMI-REVERSE CONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2021/097863
Kind Code:
A1
Abstract:
A swirl pool construction method employing semi-reverse construction, characterized by comprising the following steps: a, building a swirl pool wall cylinder by means of a forward construction method, and building segments of the swirl pool wall cylinder from ±0 m to -11.0 m; and b, building the swirl pool wall cylinder by means of a reverse construction method, performing drilling from -11 m to -14 m, using concrete to perform construction after completion of the drilling, building a well wall segment from -14 m to -17 m after the strength of the concrete reaches 75%, and building a cylinder wall from -17 m to -21.6 m and on a bottom plate after completion of the well wall construction. The present invention is a novel breakthrough compared with a conventional total reverse construction method, achieves good effects in terms of soil retaining, supporting, waterproofing, and seepage prevention, and ensures that the pool wall has high strength, high rigidity, and good impermeability. The construction is fast, and an outer cylindrical pool wall is segmented from the middle to the bottom to achieve a balance of various resources, thereby facilitating organization and coordination, improving construction efficiency, and ensuring construction progress. Workload on each construction segment is substantially equal, and materials, machines and tools, labor, and deadlines are well coordinated.
