A Triple Geotechnical Package and Its Casting Drift Calculation Method

Abstract

The invention discloses a triplet geocontainer and a method for calculating dumping drift amount thereof. The triplet geocontainer is characterized by comprising three independent geocontainers, wherein reinforcing belts are arranged at surrounding edge lines and diagonal lines of each geocontainer to reinforce. The method for calculating the dumping drift amount comprises the following steps of (1) calculating transverse and longitudinal accelerations; (2) according to an initial coordinate and speed in a time interval, obtaining a final speed and coordinate of each geocontainer in the time interval; (3) performing iterative calculation; when a longitudinal coordinate is the same as a longitudinal coordinate at a water bottom, the distance from the horizontal coordinate to the lower edge of a turning plate is the dumping drift amount. The triplet geocontainer and the method have the beneficial effects that the larger the size of the triplet geocontainer is, the larger the inertia is, and the corresponding drift amount is smaller in comparison with the drift amount of a single geocontainer; during dumping, a falling point of the triplet geocontainer is more centralized, and the falling point accuracy calculated by a falling point formula is higher, so the difficulty in construction is effectively decreased, the construction efficiency is higher, and the cost is reduced.

Description

technical field [0001] The invention relates to a triplex geotechnical bag and a calculation method for throwing drift amount thereof. Background technique [0002] Geopacks are a relatively new type of geotechnical system. In the 1980s, Nicolon B.V. developed this system and registered it as a "geotextile bag. A geotextile bag is a large-scale woven geotextile prefabricated into a "box"-shaped member with a certain width and a considerable length using a sewing machine. Use large-scale hydraulic machinery or manual filling, and finally close the filling mouth with a sewing machine or manual tying. After filling, the shape is "pillow-like" or "box-like". In recent years, geotechnical bags have been used for their convenient construction, cost-saving, The advantages of safety and reliability have quickly been widely used in water conservancy and port projects. At present, in the Yangtze River Estuary and coastal areas in my country, geotextiles are widely used in bank revetmen...

AI Technical Summary

Problems solved by technology

The disadvantage of the traditional barge-throwing large-volume geotextile construction method is that when the geotextile is thrown from the barge and hits the ground, the inclusion geotextile often breaks due to the huge load, causing serious losses

With the help of divers' exploration or ultrasonic measurement, it is found that the phenomenon of local over-throwing, local under-throwing, and runaway is still relatively common. Although the method of supplementary throwing can be used in the later stage to improve the quality of prism forming, it also increases the construction cost.
