[0002] Lake bridge construction refers to the process of building a bridge on the surface of a lake. This process includes multiple links such as bridge design, construction and installation.

[0003] Steel truss floating and pushing construction is a method of erecting large-span steel trusses.

[0022] Beneficial effects of the present invention:

[0023] 1. In the present invention, when the hull needs to move, the winch can be started to reel in the traction rope, and the hull can be dragged to move along the steel cable and the guide beam, so as to slowly adjust the position of the bridge superstructure and the supporting top frame. The guide beam and the two sets of steel cables can improve the stability of the hull on the lake. When the front end of the bridge superstructure is pushed to the shore on the other side of the lake, the compression telescopic rod is started to clamp the steel cable, and the friction force generated by the compression telescopic rod and the steel cable is used to achieve the stopping effect, so as to facilitate the fixing of the two ends of the bridge superstructure and ensure the stability and accuracy during docking.

[0024] 2. In the present invention, when installing the bridge superstructure, the two-way water pump sprays water outward to reduce the draft of the hull, maintain the relative position and overall stability of the hull, the steel cable and the guide rail beam, and ensure that the bridge superstructure can be normally docked with the supporting top frame. When the bridge superstructure is installed, a certain amount of water is injected into the air chamber through the two-way water pump to control the draft of the hull, so that the bridge superstructure can be separated from the supporting top frame, and then the steel cable on the side away from the guide rail beam is sunk underwater, and the hull is sent to the cargo position through the driving mechanism.

[0047] Working principle of the present invention: When in use, the connecting plates 3 need to be fixed on the corresponding piers 1. Every two groups of connecting plates 3 corresponding to each other form a pair. Steel cables 702 are installed between the corresponding connecting plates 3 to keep the steel cables 702 in a relaxed state. A winch 6 is installed on the piers 1 in the extension direction of the bridge body. Then, two groups of fixed cables 503 are installed between a pair of connecting plates 3. The fixed cables 503 are put in a tense state as a whole by means of a cable winding device. Then, the tense state of the two groups of fixed cables 503 is maintained by means of four groups of first tensioning machines 502. A U-shaped plate 5041 is placed on the fixed cables 503 so that the pulley 5044 inside the U-shaped plate 5041 contacts the corresponding fixed cables 503.

The steering gear adjusts the output direction of the conveying cylinder 904 to push the hull 401 to move in the corresponding direction. The front end of the bridge superstructure 2 is pushed to the supporting top frame 404 and fixed by the pushing device on the shore. The staff can drive the hull 401 into the construction position, and then fine-tune the position of the hull 401. The two-way water pump 801 outputs part of the water inside the air chamber 806, thereby controlling the draft depth of the hull 401, ensuring that the bridge superstructure 2 can be normally docked with the supporting top frame 404, and adjusting the telescopic length of the L-shaped telescopic hook 405 so that the L-shaped telescopic hook 405 can be hung The hull 401 is loaded onto the guide rail beam 5, and the relative position and overall stability of the hull 401, the steel cable 702, and the guide rail beam 5 are maintained. The steel cable 702 is then tightened by the rope winding device, and the positions of the two sets of steel cables 702 are adjusted so that the two sets of steel cables 702 enter the corresponding cable grooves 402 respectively. After the steel cables 702 are tightened, the two ends of the steel cables 702 are fixed by the second tensioning machine 701 to ensure that the steel cables 702 have a certain tension, and then the front end of the hull 401 is connected to the traction rope of the winch 6;

[0049] The winch 6 winds up the traction rope and drags the hull 401 along the steel cable 702 and the guide beam 5, thereby slowly adjusting the position of the bridge superstructure 2. When the front end of the bridge superstructure 2 is pushed to the shore on the other side of the lake, the compression telescopic rod 501 is started to clamp the steel cable 702, and the friction force generated by the compression telescopic rod 501 and the steel cable 702 is used to achieve a stopping effect, thereby facilitating the fixing of both ends of the bridge superstructure 2;

[0050] After the bridge superstructure 2 is fixed, the L-shaped telescopic hook 405 is adjusted to be separated from the guide beam 5, and all the second tensioning machines 701 are opened to loosen the two sets of steel cables 702, push both sets of steel cables 702 away from the cable groove 402, and remove the connection between the bridge superstructure 2 and the supporting top frame 404. The two-way water pump 801 sprays water outward to reduce the draft of the hull 401, and sinks the steel cables 702 on the side away from the guide beam 5 underwater to avoid obstruction to the hull 401. The hull 401 is sent out of the construction position through the driving mechanism 9, and then the guide beam 5 is removed, and the installation of the bridge superstructure 2 is completed.
