Engineering machinery construction channel in debris flow state alluvial soil area

Abstract

The invention discloses an engineering machinery construction channel in a debris flow state alluvial soil area, comprising more than two channel assembling units which are spliced, wherein each channel assembling unit comprises load-bearing units, an externally wrapping bottom plate and supporting side walls, wherein the outer bottom surface of each load-bearing unit is wrapped with the externally wrapping bottom plate; two opposite side edges of each load-bearing unit are respectively provided with the supporting side walls; two adjacent load-bearing units are connected through a rotating bolt; and two adjacent supporting side walls are connected through a riveted water seal rubber sheet. Thus, the invention is suitable for the overlapping and laying work of a fast channel in a large-area shallow alluvial soil area, provides a prerequisite condition for the smooth development of rescue and relief work, assemblies a fast channel overlapping device by adopting standard assemblies in amodularizing way, has simpleness, convenience, fastness, reliable connection and high overlapping and assembling efficiency and can autonomously select the direction of the channel without presettinganchor cable positioning and open the fast construction channel suitable for medium and small sized construction machinery to fast pass in areas seriously deposited with debris flows and the like.

Description

technical field [0001] The invention relates to a construction channel for engineering machinery, which belongs to the technical field of disaster prevention and mitigation engineering in civil engineering. Background technique [0002] Debris flow is a torrent formed by torrential rains and floods after saturation and dilution of soft soil mountains containing sand and stones, with large area, volume and flow. A typical debris flow is composed of viscous mud with coarse solid debris suspended and rich in silt and clay. Under appropriate terrain conditions, movement occurs to form a debris flow. Debris flows can directly bury stations, railways, highways, even cottages and towns, destroy roadbeds, bridges and culverts and other facilities, resulting in traffic interruption. Sometimes the mud-rock flow merges into the river course, causing the river course to change drastically, causing severe flood disasters and causing huge economic losses. For example, on August 7, 2010,...

Problems solved by technology

[0004] The passage facilities usually used are the bridging equipment of the People's Liberation Army's pontoon bridge unit, the opening equipment of the rescue and relief team, etc., but there are still large quantities of engineering, high cost, inapplicability, and engineering machinery that cannot be carried out in the fast and large-area shallow fluid mud area. The difficulties in the field have seriously hindered the disaster relief process
