Embodiment Construction

[0047] The present invention is described in detail below in conjunction with accompanying drawing.

[0048] A method for emergency rescue using a limited-depth convenience bridge, using a portable bridge cage emergency device and a bridge leg depth stopper to build a limited-depth temporary bridge for emergency operations, and the portable bridge cage rescue device includes a plug-in board module 1 and a steel drill column bridge pile module 2 and a locking module 3, the plug-in module 1 is horizontally connected in series and supported and fixed by the steel-drilling-pillar bridge pile module 2, and the locking module 3 is used to lock the plug-in board module 1 and the steel-drilling-pillar bridge pile module 2 in Together.

[0049] The plug-in module 1, the steel drill column bridge pile module 2 and the locking module 3 can be metal materials or high-strength non-metal materials.

[0050] The steel drill column bridge pile module 2 is composed of steel drill units 21 in ...

Abstract

The invention relates to the field of flood prevention and rescue of the Yellow River, in particular to a method for building a depth-limited temporary bridge for emergency rescue. According to the method, a temporary bridge for emergency rescue is built by the aid of a portable bridge cage emergency rescue device, when legs of the temporary bridge are installed, bridge leg depth limiting devicesare directly clamped at reserved positions of the bridge legs, and then the temporary bridge is used for carrying out throwing operation. According to the method, the devices building the temporary bridge can be quickly assembled on site, a cage-based-leg temporary bridge is built at the position of a breach, the bridge leg depth limiting devices are utilized to solve the problems that load bearing capacity of the rapidly-built temporary bridge is low and the bridge is prone to inclination and stability loss, effective repair can be carried out timely when a dam is burst, the temporary bridgetransportation is convenient and fast, the construction steps are simple, and the application range is wide.

Description

technical field [0001] The invention relates to the field of flood control and emergency rescue of the Yellow River, in particular to a method for emergency rescue using a limited-depth access bridge, and the IPC international patent classification number is E02B 1 / 00. Background technique [0002] River breaches are very harmful. For example, in 1998, catastrophic floods occurred in my country's Yangtze River, Songhua River and other rivers, which brought huge economic losses and casualties to the cities and counties around the river. Although the final breach is blocked by adopting the current blocking breach technology. However, because it requires personnel to stand in the torrent for piling construction, such as "River Breach Soft Plugging Method" (99115001.5) or personnel operate boats and vehicles to sink and plug leakage, such as "Break Break, Dam Break Blocking Ship" ( 201521008895.X), the price paid was also extremely heavy. Therefore, the high-efficiency and saf...
