Deepwater bagged sand construction device and deepwater bagged sand construction technology

Abstract

The invention relates to a deepwater bagged sand construction device and a deepwater bagged sand construction method. The deepwater bagged sand construction device is characterized by comprising an opposite pull boat (1) arranged at one side of a sand bag (2), and an opposite pull auxiliary boat (3) which is arranged at the other side of the sand bag (2) and is paired with the opposite pull boat (1), wherein the opposite pull boat (1) is fixed by four reversed V-shaped opposite pull anchor cables (11), wherein two of the opposite pull anchor cables (11) are arranged at the front, and the other two opposite pull anchor cables (11) are arranged at the back; the opposite pull auxiliary boat (3) is fixed by four reversed V-shaped opposite pull auxiliary anchor cables (31), wherein two of the opposite pull auxiliary anchor cables (31) are arranged at the front, and the other two opposite pull auxiliary anchor cables (31) are arranged at the back; the opposite pull boat (1) is provided with two hoisting machines (4); the opposite pull auxiliary boat (3) is also provided with two hoisting machines (4); the four corners of the sand bag (2) are respectively connected with four pull ropes (5) by a slipknot; the other ends of the two pull ropes arranged at the same side with the opposite pull boat (1) are respectively fixed on the two hoisting machines (4) of the opposite pull boat (1); the other ends of the two pull ropes arranged at the same side with the opposite pull auxiliary boat (3) are respectively fixed on the two hoisting machines (4) of the opposite pull auxiliary boat (3); the opposite pull boat (1) is provided with a slurry pump (6); an outlet of the slurry pump (6) is connected with an entrance of the sand bag (2). The device and the method can enable a sand bag body to be more accurately located and settled.

Description

technical field [0001] The invention relates to a deep-water bagged sand construction device and process. Background technique [0002] At present, the construction device for bagged sand in deep water generally adopts laying boats. The hull of this kind of laying boat is very large, because the length of sand bags for deep water bagged sand generally ranges from more than 20 meters to hundreds of meters long. The length direction is laid on the flap of the laying ship. The flap is set at an inclination relative to the hull. One side of the flap is fixed on the hull, and the other side extends into the water obliquely. During the construction process, one side fills the sand bag with mud sand , while laying the boat back, as the weight of the sandbags increases, the sandbags will gradually sink to the bottom of the water. The main disadvantages of the traditional deep-water bagged sand construction by laying boats are: the use of bulky laying boats is required, and the cost...

AI Technical Summary

Problems solved by technology

The main disadvantages of the traditional deep-water bagged sand construction by laying boats are: the use of bulky laying boats is required, and the cost is high. In addition, when the water depth is large, the water flow is complicated, and the efficiency of sand bag laying is not high. The sand bag between the boards is easily disturbed by the water flow, resulting in distortion and damage. The laying quality is difficult to meet the specification requirements, and it is difficult to lower it to the design position. The success rate is not high
