A floating navigation facility in deep water reservoir area based on multi-directional limit connection mechanism

Abstract

The invention discloses a deep reservoir area floating type navigation device based on a multidirectional limiting connecting mechanism. The deep reservoir area floating type navigation device comprises steel pipe piles and a steel wharf boat. The steel pipe piles are connected with steel wharf boat limiting walking mechanisms. The steel wharf boat is limited between the two steel pipe piles through the mechanisms. The upper portion of the steel wharf boat is composed of a mechanism frame, a limiting walking bearing and wheels. A frame foundation is composed of four end pillars and two diagonal shores and is connected with a wheel trolley beam through a connecting beam arranged on an end pillar. Eight wheels are arranged on the limiting walking mechanism on each side of the wharf boat. Each steel pipe pile is composed of a vertical walking rail tread which is in a triangular shape. By means of the structure, the parts are arranged according to a walking structure and are arranged on the outer sides of the steel pipe piles, and the parts are connected with the steel pipe piles in a continuous welding manner. By means of the deep reservoir area floating type navigation device, the requirement for bearing force of the floating wharf boat under floods and a ship pile can be met through the limiting walking mechanisms, and the functions of vertically floating walking, horizontal limiting, lateral limiting and clamping, garbage clamping preventing and the like of the wharf boat are also achieved.

Description

technical field [0001] The invention belongs to the technical field of water transport engineering, and in particular relates to a floating navigation facility in a deep water reservoir area based on a multi-directional limit connection mechanism. Background technique [0002] With the rapid development of my country's economy, the volume of water transportation has also increased rapidly. The average annual growth of my country's waterway freight volume and cargo turnover is 6.7% and 6.6%. In 2005, waterway freight volume and cargo turnover accounted for 11.8% and 61.9% of the total volume of various transport modes respectively. In order to meet the increase in cargo volume, it is necessary to expand new navigation buildings on the basis of improving the passing capacity of the original navigation facilities. [0003] In our country, limited by the technology and economic level at that time, quite a few projects and hubs did not leave the location for the construction of ...

AI Technical Summary

Problems solved by technology

[0005] In the hub ship lock, the floating navigation structure built in the reservoir area is generally composed of pier body or pile foundation + floating pontoon, in which the connection structure between the barge and the piles and pier on both sides plays a vital role in the normal operation of the facility. First of all, after the pile piers and barges are designed to bear the load according to the structure, the connection link becomes a weak link of load bearing; secondly, according to the current survey of reservoir areas in China, there are still a large proportion of floating objects and garbage, especially in the flood season. Garbage on both sides of the strait gathers at the front of the dam along with the flood, and part of it is discharged downstream through the spillway along with the flood. However, at the front of the ship lock, because most of the locks are closed during the flood season, floating debris collects more, and it is easy to cause a floating structure. Jamming is caused at the connection part; in addition, due to the large scale of the floating pontoon in the reservoir area, unbalanced floating and swaying are easily caused by the action of the current. If the connection mechanism is not properly set, it is also easy to cause jamming, and even the pontoon sinks and damages the pile Accidents such as piers

[0006] According to investigation and research, the current conventional connection methods and problems are as follows: ①Using the tenon joint between the track groove and the slider or roller on the pontoon, this method will cause floating objects in the reservoir area to fill the track groove, and often block the track groove and the pontoon. The barge cannot float or one side is stuck; ②Anchor chain is used to connect the pier, which will also cause floating objects and other garbage in the reservoir area to block the floating structure, and the barge cannot float. The pontoon drifts under the flood with large pitch and roll, which affects the safety of the structure; ③The ring-shaped pile holder is used to connect the pile. The navigation structure with large size and lots of rubbish in the storage area will also be jammed
