Problems solved by technology

Because caissons need to be transported by tide, most of them are constructed at night. Manual measurement cannot accurately grasp the dynamic data and overall posture of caissons. The construction experience of the construction team, without theoretical knowledge support, has the disadvantages of subjectivity and partiality

Embodiment 1

[0047] The control method of the caisson shipment control device provided by the present invention comprises the following steps:

[0048] Step 1, install the data monitoring device on the caisson 3: before installing the closure cover of the caisson 3, install the liquid level gauge 11 on the bottom plate of the caisson compartment 10cm upwards; 12; After the caisson 3 closing cover plate is installed, install the collection box 13 and the power supply unit 14 on the closure cover plate 31 of the caisson; the power supply unit 14 is connected with the collection box 13, and the collection box 13 passes through the four-core cable 15 and The liquid level gauge 11 is connected with the inclinometer 12; after that, the caisson 3 starts to move to the upper dock;

[0049] Step 2, caisson 3 shipped:

[0050] After the floating dock 4 loaded with caissons is towed by tugboat 2 from the caisson prefabrication yard to the sinking pit for positioning, the water engineering team install...

Embodiment 2

[0063] Step 1, install data monitoring device on caisson 3:

[0064] Before the caisson 3 closing cover plate is installed, a liquid level gauge 11 is installed 10 cm above the caisson cell bottom plate, and the liquid level gauge 11 is fixed on the floating hook 32 of the caisson 3 by a snap ring and covered with a waterproof cloth 33; in the caisson 3 The front wall and the side wall of the top floor are respectively arranged with an inclinometer 12, and the inclinometer 12 is fixed on the outside of the front wall and the outside of the side wall of the caisson 3 through an iron expansion tube. The four-core cable 15 connected between the liquid level gauge 11, the inclinometer 12 and the collection box 13, because the four-core cable 15 cannot bear force, is therefore temporarily connected with the pre-embedded round table on the caisson partition wall, and insulation measures are taken. After caisson 3 closure cover plate is installed, on the closure cover plate 31 of cai...

Abstract

The invention discloses a caisson shipping control device and a caisson shipping control method, and relates to the technical field of water transportation engineering, in particular to the caisson shipping control device and the caisson shipping control method. The caisson is provided with a data monitoring device, the data monitoring device comprises a liquid level meter, inclinometers, a collection box and a power supply device; the liquid level meter is arranged at a bin bottom plate of the caisson, the inclinometers are arranged on the front wall and the side wall of the top layer of the caisson, and the collection box and the power supply device are arranged on a bin sealing cover plate of the caisson; the power supply device is connected with the acquisition box, and the acquisition box is connected with the liquid level meter and the inclinometer; a tug is provided with a repeater; after the repeater is wirelessly connected with the acquisition box, a bus signal is transmitted to the receiver; a receiver is connected with a 485 concentrator; and the 485 concentrator transmits the signal to a central control room. According to the invention, a safety management mode integrating real-time monitoring, dynamic analysis and danger early warning of caisson shipping is realized, and a precedent is provided for building an intelligent water transportation construction system.

Description

technical field [0001] The invention relates to the technical field of water transportation engineering, in particular to a caisson transportation control device and a control method thereof. Background technique [0002] At present, with the deepening of the globalization trend of the world, the port business types are extensive and professional, which poses higher challenges to the terminal construction. The specific characteristics are as follows: [0003] 1. The construction period of the wharf project is tight and the tasks are heavy. The owner requires the investment project to be put into production as soon as possible. As the key point of the project progress, the caisson is out of operation, and the improvement of efficiency requires the guarantee of safety and quality. The control point lies in the dynamic monitoring of the stability of the caisson. [0004] 2. The structural forms of the caisson are gradually diversified, such as the hollow type with wave-dissipa...
