Technical Field

The invention belongs to the technical field of amphibious landing combat obstacle crossing, and particularly relates to an amphibious obstacle crossing trestle.

Background

The forces of future army landing operations mainly comprise navy land warfare teams for executing early beach landing tasks and exquisite synthetic teams for executing later depth propulsion tasks. The naval land battle team is used as a first attack wave to carry out beach-rushing and landing operations, a beach position is quickly established under the guarantee of beach-rushing fire of our army, and good conditions are created for the subsequent troops to land.

The main obstacles hindering the navy land battle team from maneuvering in the beach landing operation are artificial obstacles and natural obstacles. The artificial obstacles include triangular cones, muddy fields, barrier walls, mines and the like; the natural obstacles include reef groups, cliff and the like. Regarding the artificial obstacle, the traditional obstacle breaking mode of our army takes fire obstacle breaking as a main means, such as an obstacle breaking bomb, an obstacle breaking boat, a mine sweeping bomb and the like; the remaining obstacles of 'digging, clamping and lifting' of the amphibious engineering operation vehicle are taken as auxiliary means, such as a triangular cone and the like. The traditional mode depends on dense firepower to break obstacles, the obstacles cannot be cleared by 100 percent, the auxiliary sweeping of an amphibious engineering operation vehicle is still needed, and the efficiency is not high. And the natural obstacle has no quick and effective obstacle crossing means or equipment. How to quickly sweep and overcome the obstacles and open up a plurality of landing paths is a difficult problem for naval army troops.
