Dredging and dumping construction process
The invention provides a desilting, throwing and filling construction process which comprises the steps that a construction area located between a mountainous area and a lake island is partitioned, a riprap and silt squeezing area formed by a col area and a desilting and backfilling area of a three-face mountain-surrounding water area are formed, the riprap and silt squeezing area is constructed in a land pushing and backfilling mode, the water depth of the riprap and silt squeezing area is 0.3-1.4 m, and the replacement depth is smaller than 2.5 m; the backfill area is a construction area which is subjected to water throwing and land throwing after desilting is completed. Water throwing is conducted in a layered throwing and filling mode, and land pushing is conducted with the riprap slope ratio not smaller than 1: 1.5; in the water throwing and land pushing backfilling process, the filling rate is controlled in real time to be always within the set range, and in the land pushing process, a plurality of arc-shaped throwing and filling structures are formed and propelled towards the sea side. The method has the advantages and characteristics of being large in work amount, high in speed, high in strength and short in construction period in the large-area desilting and backfilling process.
本发明提供了清淤抛填施工工艺，包括将位于山区和湖岛之间施工区域分区，形成山坳区构成的抛石挤淤区以及三面环山水域的清淤回填区，所述抛石挤淤区通过陆推回填的方式施工，所述抛石挤淤区为水深0.3m～1.4m，置换深度小于2.5m的区域；所述回填区为清淤完成后先水抛后陆抛的施工区域。水抛按照分层抛填的方式，陆推以抛石坡比不小于1:1.5进行施工；水抛和陆推回填中，则实时控制填筑速率，使其始终处于设定的范围内，且陆推中，形成若干个圆弧状的抛填结构，朝向海侧推进。本发明实现了大面积清淤和回填工艺中，工程量大、速度快、强度高、工期短的优点和特点。
