Description

Technical Field

[0001] The utility model relates to the technical field of waterway reef clearing and dredging, in particular to a buoy monitoring device for reef clearing and dredging. Background Art

[0002] In the context of globalization, the navigability of a country or region's ports and waterways largely determines its competitiveness in international freight and trade. The quality and efficiency of reef clearing and dredging projects are crucial to ensuring the navigability of ports and waterways. First, when ports and waterways are adequately dredged, their capacity and efficiency are significantly improved, allowing more ships to enter and exit ports more quickly. This is crucial for meeting the stringent timeliness requirements of international trade. Furthermore, improved speed and efficiency in the entry and exit of goods from a country or region not only accelerates the circulation of international trade and improves capital turnover, but also significantly reduces the time spent waiting in ports, thereby lowering overall logistics costs. Second, the good condition of ports and waterways enhances the overall quality of service, attracting more international ships and cargo owners to choose these ports as transit or terminal points, strengthening the region's cooperative relations with other countries and regions. Finally, cooperation between countries or regions often requires a certain logistics and shipping infrastructure. Well-executed dredging strategies and engineering construction will enhance a region's bargaining power in cooperation with other countries or regions by providing more reliable and efficient logistics support.

[0003] Existing construction methods make it difficult to carry out channel dredging while ensuring the channel is navigable. Therefore, the applicant improved the channel reef clearing and dredging construction method during actual construction, which simply includes the following steps: S1 pre-construction preparation; S2 establishment of a measurement and positioning system; S3 setting up construction strip buoys; S4 positioning of construction vessels and docking of mud barges for construction vessels to transport mud; S5 establishment of a construction early warning system; S6 excavation and horizontal and vertical movement of construction vessels; S7 measurement and acceptance of the excavation area. The above method adopts dynamic space management and modular construction methods. It can carry out channel reef clearing and dredging while ensuring the normal navigation of the channel during construction, reduce economic losses caused by the project, use the early warning system to reduce the occurrence of engineering accidents, and ensure the safety of the original bridge.

[0004] In the process of setting up construction strip buoys, it is necessary to divide the dredging strip width according to the dredging construction drawings and coordinate system, and set up construction buoys according to the strip width as auxiliary construction positioning measures; the buoys must be accurately positioned when placing them, and the distance between each buoy should not be greater than the designed strip width. According to the existing waterway, the construction range can be divided into half-width construction and half-width navigation, which is applicable to different excavation layers. At the same time, warning signs and traffic flashing lights must be set up on the construction ships, and traffic ships will organize the traffic of ships coming and going; the strip buoys contain warning lights, reflective tapes and alarm devices, which mainly serve as night warnings and alarms. However, the existing buoys cannot meet the above-mentioned needs of construction auxiliary positioning and construction information interaction. Therefore, it is particularly necessary to develop a new type of buoy monitoring device to improve construction safety and efficiency. Utility Model Content

[0042] Reference Figure 4 , the implementation principle of this embodiment is:

[0043] S1 Pre-construction Preparation: The project department's construction technicians have been fully familiar with the design drawings and relevant technical documents. The surveying team has conducted a comprehensive review of the excavation surface elevation position. The engineering department and on-site personnel have a comprehensive understanding of the site geology. Technical problems and objections in the drawings have been properly resolved. The overpass and underpass pipelines have been clearly mapped out, and the construction vessels, excavators and transport vehicles have been put in place.

[0044] Establishment of S2 measurement and positioning system: Based on the coordinate control points given by the design unit, i.e., the preset construction coordinates, a waterway dredging construction measurement control network is established. A custom construction coordinate system is also established based on the needs of the project construction. During construction, the construction vessel is positioned along the Qujiang River, and the construction vessel is controlled by shipboard GPS.

[0045] S3: Set up construction strip buoys: Divide the dredging strip width according to the dredging construction drawings and coordinate system, and set up construction buoy monitoring devices according to the strip width as auxiliary construction positioning measures; the buoy bodies 1 must be accurately positioned when placed, and the spacing between each buoy body 1 should not be greater than the designed strip width. According to the existing waterway, the construction range can be divided into half widths for construction and half widths for navigation; set up warning signs and traffic flashing lights on ships, and transport boats will organize the traffic of ships;

[0046] S41 Construction Vessel Positioning: A construction vessel using a positioning pile uses anchor cables to position itself. Two positioning piles are installed in the middle of the vessel, and positioning and movement are achieved by the lifting and lowering of the two positioning piles during construction. After the vessel enters the construction area, it is accurately positioned using the vessel's GPS terminal, and the positioning piles are driven into the riverbed before dredging operations can begin.

[0047] The S42 mud barge berths the construction vessel to transport mud. This project adopts the method of lifting the stern and exchanging the barge. The empty barge is hoisted to the stern of the heavy barge. When the tugboat tows away the heavy barge, the empty barge is winched into place by the construction vessel.

[0048] The establishment of the S5 construction early warning system monitors construction safety through GPS positioning of passing ships;

[0049] S6 Excavation and lateral and longitudinal movement of construction vessels: The modular construction vessel shall first be dredged and shallowed to ensure the draft requirements of the bottom-opening barge and other working vessels. Before construction, a trial excavation shall be carried out before the formal excavation of each construction section, and experienced operators shall be selected to operate the dredging technical parameters such as the optimal cutting thickness, advance distance, main engine speed, etc. of the construction vessel to achieve the best construction effect and dredging efficiency. The bucket construction vessel shall adopt the construction method of reverse downstream excavation.

[0050] S7: Survey and acceptance of excavation area; Excavation during construction must be ensured to be extra wide and extra deep as per design requirements, with side slopes designed for pebbles and bedrock; before construction, surveyors must use BeiDou for precise positioning before dredging can begin; the lateral movement distance of the construction vessel cannot exceed 2m, and the longitudinal distance cannot exceed the bucket width; when lowering the bucket, the bucket positions must overlap by 1 / 3 to 1 / 4 of the bucket width to ensure that no dredging is missed; waste should be dumped into the designated dumping area, and the depth of the dumping area should be monitored at all times; during construction, water level changes and the bottoming depth of the grab bucket should be continuously observed; at the same time Special personnel should also be assigned to carry out lookouts and pay close attention to the passing of ships upstream and downstream; after dredging of an area is completed, the area needs to be self-inspected to ensure that there are no shallow spots in the water within the designed bottom line and that the slope, extra width and extra depth meet the design requirements; the excavated slope should not be steeper than the designed slope, and the extra width on each side should not be greater than 4m; construction records should be made according to the drawings, and the low elevation of the riverbed should be measured before dredging. During the construction process, process measurements should be made at least once a week and reported to the supervising engineer as required. After passing the inspection, construction will proceed to the next construction area.

[0051] Since there is a certain height difference between the excavated mud surface and the original mud surface during the excavation process, the overlap between the next shovel and the previous shovel can be controlled within the range of 1 / 4-1 / 3 of the shovel. If a geologically poor area is encountered, the overlapping range can be appropriately increased. After the construction is completed, professional remote control equipment is used to scan and draw a scanning map. Targeted measures are taken based on the scanning results to ensure that the bottom elevation and flatness of the channel meet the requirements. (1) The excavation range within the design bottom line must meet the design requirements, and the excavation section must not be less than the design section. (2) The dredging of this project is a dredging project without a reserve siltation depth. No shallow points should appear in the waters within the design bottom line.

[0052] Among them, the construction ship adopts strip-by-strip construction: (1) When the width of the trench exceeds the width that the bucket construction ship can excavate at one time, the construction should be carried out in strips. The strip width should be determined according to the rotation radius and rotation angle of the bucket under the current excavation depth conditions. The rotation angle should be appropriately reduced when digging hard soil and appropriately increased when digging soft soil; (2) When the mud layer thickness is too large, the excavation should be carried out in layers. The layer thickness should be determined according to the bucket height and the excavated soil quality. The layers should be thick when digging soft soil and thin when digging hard soil. The layer thickness should generally not exceed 1.8~ 2 times the bucket height; (3) When excavating, excavate from upstream to downstream, the single excavation thickness is 1m, the maximum excavation thickness of the entire line is 3m, and the excavation is carried out in layers of 1m. The last excavation is controlled according to the actual bottom elevation. If it is less than 1m, it should be strictly controlled; (4) The overlapping width of the strips is one-third of the rotation radius of the excavator. The rotation radius of the excavator is 3.5m, so the overlapping width of the strips is 1.2m; when the bucket is lowered, the bucket position overlaps 1 / 3 of the bucket width, specifically 40cm, to prevent missing excavation.

[0053] In addition, for the disposal of silty clay and bedrock, the dredged earthwork is transported using a 200-ton open-bottom barge. Construction ships excavate and dump mud onto the open-bottom barge, which is then transported to the shore along the predetermined transportation route. Long-arm excavators are then used to unload the mud into dump trucks, which are then transported to designated earthwork storage locations and unloaded at a simple dock.

[0054] The above method can carry out reef clearing and dredging projects in the waterway while ensuring normal navigation during the construction process, and adopt dynamic space management and modular construction methods to reduce economic losses caused by the project; the segmented buoys used in the construction contain warning lights, reflective tapes and alarms, which mainly serve as night warnings and alarms; the positioning of construction ships adopts Beidou, which is more accurate; high-frequency rock hammers are used during construction and can dredge the waterway with the lowest possible disturbance to the surrounding soil layer, and are suitable for various silt layers; the use of early warning systems reduces the occurrence of engineering accidents and ensures the safety of the original bridge.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
