Embodiment Construction

[0012] In order to further understand the content of the invention, features and effects of the present invention, the following examples are given in detail as follows:

[0013] The long-distance sand blasting construction technology of the present invention comprises the following steps,

[0014] (1) The steps for the ship to sail to the sand taking place;

[0015] It also includes the step of installing rams on the energy dissipation boxes of the hatches to adjust the plugging, that is, installing rams on the energy dissipation boxes at the rear of the front loading hatch and the front of the rear loading hatches respectively to block the openings, Reduced rearward jetting of forward loading hatch mud flow and forward jetting of aft loading mud flow.

[0016] (2) The step of injecting water into the mud tank of the ship to the full tank state;

[0017] (3) Follow the set dredging route to take sand and carry out the steps of taking sand;

[0018] In this step, the soil c...

Abstract

The invention relates to a long-distance sand taking and throwing construction technology. The long-distance sand taking and throwing construction technology comprises the following steps that (1) a ship sails to a sand taking position; (2) water is injected into a mud cabin of the ship till the cabin is in a full state; (3) according to a set mud digging and sand taking ship route, travelling and sand taking are conducted; (4) by adjusting the heights of a left overflow cylinder and a right overflow cylinder and switches of a front cabin loading valve and a rear cabin loading valve, ship transverse inclination and the fore and aft immersion depth are automatically adjusted; (5) the heights of the left overflow cylinder and the right overflow cylinder are adjusted to be consistent; (6) the heights of the two overflow cylinders are decreased synchronously with increasing of the sand taking quantity; (7) sand taking is conducted till full loading of the ship; and (8) sailing back is conducted for sand throwing. According to the long-distance sand taking and throwing construction technology provided by the invention, a lot of problems that under an existing sand taking technology, ground breaking is difficult, the quantity of sandy mud contained in a sand source area is increased, cabin loading is uneven, and ship body sagging occurs are solved, and the efficiency for sand taking and throwing of the ship is promoted.

Description

technical field [0001] The invention belongs to the technical field of dredging construction, in particular to a long-distance sand-taking and throwing construction technology. Background technique [0002] With the development of China's economy, the demand for land resources is increasing, and there has been a wave of land reclamation in China. However, there are fewer and fewer sand sources in the offshore, so the required sand sources tend to be more and more in the deep sea to meet the needs of land reclamation. As a self-propelled dredging ship capable of self-propelled, self-digging, self-loading and self-unloading functions, the trailing suction ship has become the first choice for sand extraction projects. [0003] However, in recent years, the lack of experience in this kind of ship engineering and the unskilled operation of personnel are currently unavoidable problems. In order to accumulate construction experience, provide technical support for follow-up simila...
