Inning casting construction spur dike construction method in strong tidal bore area

Abstract

The invention discloses an inning casting construction spur dike construction method in a strong tidal bore area. The method comprises the following steps of (a), construction preparing; (b) stone exploiting; (c) measuring and staking out; (d) in-position of dump tucks and barges; (e) performing bottom protection by casting of the barges; (f) propelling by small spring tides; (g) widening and heightening by large spring tides; (h) protecting the slopes of two sides of a spur dike by casting of the barges and extending to perform the bottom protection. According to the inning fusing construction spur dike construction method in the strong tidal bore area, the wastage rate of rocks when the rocks are cast in the strong tidal bore area is reduced, the dike stability is kept, the work period is shortened, the construction progress is accelerated, the environment is protected, massive manpower and labor and investment of machinery equipment are saved, the engineering construction cost is reduced, and when the spur dike is built, the bottom protection is performed firstly by the casting of the barges to prevent the earthwork of the dike head from degradation, and the wastage of the rocks of the dike head caused by washing of spring tides is reduced.

Description

technical field [0001] The invention relates to a construction method of a riprap spur dam. Background technique [0002] With the promulgation and implementation of a series of regulations and regulations such as the "Regulations on the Management of Tidal Flat Reclamation in Zhejiang Province" and the "Overall Plan for Tidal Flat Reclamation in Zhejiang Province", tidal flat reclamation has been included in the administrative licensing items stipulated by Zhejiang Province, and tidal flat reclamation in Zhejiang Province has gradually embarked on Legalization, standardization and scientific road. The Xiaoshan River Control Project is located in the area with the strongest tidal surge of the Qiantang River. The riverbed is low and it is close to the deep river. It is necessary to carry out deep water siltation promotion in the strong tidal surge area. Difficulty and many other practical difficulties. The current construction method adopts the occupation method to unload a...
