Soft mattress paving method

Abstract

The invention provides a soft mattress paving method, which is applied to paving of a mattress body through a paving ship. The mattress body comprises mattress cloth and concrete interlocking blocks or sand ribs, and a plurality of underwater beacons, a transceiver and a control unit; the transceiver is arranged at the bottom of the paving ship and is connected with the control unit; and the three-dimensional positions of the underwater beacons relative to the transceiver can be collected by the control unit and the transceiver through transmission of sound pulse signals between the underwater beacons and the transceiver. By introducing the underwater beacons and the transceiver, real-time positioning of the mattress body can be realized in paving of the soft mattress, real-time and accurate feedback and control of the construction process can also be realized, and the soft mattress paving method is more economical, more environmentally friendly, quicker and more accurate.

Description

technical field [0001] The invention relates to a construction method for laying underwater soft bodies. Background technique [0002] With the rapid development of coastal and inland economies and port construction, there are more and more coastal land reclamation projects and waterway construction and improvement projects. The implementation of these projects is generally inseparable from the bottom protection construction. The software row is currently used The most extensive form of bottom protection, the laying quality of the soft row also directly affects the safety of the building.

Problems solved by technology

[0003] At present, the laying of soft platoons mainly depends on the construction of large-scale professional laying ships. Construction ships are generally equipped with GPS positioning system construction software. The movement of ships and the lowering of soft platoons can basically realize automatic operation, but the current construction positioning software reflects the laying contour of soft platoons. It is only the theoretical laying position, which actually reflects the positioning and moving distance of the construction ship. The actual position, longitudinal and lateral displacement of the soft row cannot be reflected intuitively. Therefore, the laying accuracy of the soft row has certain limitations.

In the past, after the laying of the soft row, the detection of the amount of adjacent overlapping underwater and the actual laying position of the soft row is mainly realized by the method of pre-tied buoys on the water surface, straightening on the water, using GPS to pick points and diving underwater to touch the actual overlapping method. Due to factors such as the large error of buoy straightening on the water and the limited ability of divers to explore and judge underwater, it is impossible to accurately reflect the laying accuracy and laying quality of the underwater soft row, and the construction efficiency is low, which also restricts the laying construction efficiency and key to quality

[0004] In addition, in foreign software paving construction, in terms of bunker detection, there is a method of using underwater cameras for inspection, but the use of underwater cameras for inspection has very high requirements for the water environment. On the one hand, the water depth should be shallow, generally not exceeding At the same time, the water quality should be clear, if the water body is turbid, the corresponding work cannot be carried out; on the other hand, the underwater camera cannot determine the exact position of the underwater soft body row, and the guiding significance for the construction is not obvious; at the same time, the water body suitable for underwater photography The environment is difficult to exist on the construction site, and projects completed at home and abroad are rare, and its applicability is relatively limited
