Description
Technical field
The present invention relates to a kind of engineering machinery construction passage, belong to anti-mitigation field of engineering technology in the civil engineering.
Background technology
Mud-rock flow is that heavy rain, flood will contain sandstone and the soft soil property massif mighty torrent through saturated dilution back formation, and area, volume and flow are all bigger.Typical mud-rock flow under suitable orographic condition, moves the formation mud-rock flow by suspending thick solid debris thing and be rich in flour sand and the thickness mud of clay is formed.Mud-rock flow can directly bury the station, and facilities such as roadbed, bridges and culverts are destroyed in railway, highway even cottage cities and towns, cause interruption of communication.Sometimes mud-rock flow imports the river course, causes river course transition significantly, causes serious flood and causes enormous economic loss.For example on August 7th, 2010, the bust heavy showers of Zhouqu County, Tibetan Autonomous Prefecture of Gannan is let out under the Luo Jiayu on north, county town, three valley mud-rock flows, rushes at the county town by north orientation south, causes along the river that the house is destroyed by rush of water, and mud-rock flow blocking-up white Dragon River, forms barrier lake; On August 11st, 2010, Longnan City, the Shaanxi heavy rain that happens suddenly within the border causes geological disasters such as mud-rock flow, landslide, causes traffic highway section, many places to be stopped up, and the power communication facility interrupts, institutional settings, industrial enterprise and residenter house water inlet or collapse.
Mud-rock flow causes serious disaster, causes huge life and property loss, and for recovering disaster area ordinary production life order, rebuilding in disaster-hit areas just becomes the key of rescue and relief work.Mud-rock flow later remains a large amount of fluidised form thickness mud, and depth of mud is not of uniform size, causes disaster relief personnel, the emergency work machinery difficulty of marching into the arena, and relief goods such as can't transport smoothly at difficulty.Adopted the helicopter means of transportation in the past in the disaster relief, but have high risk under bad working environments and weather condition, and the air transport freight volume is limited, freight rate is high.Thereby the laying of disaster area rescue road just becomes key one ring of whole disaster area rescue work.
The bridge formation equipment that the common channel establishment that adopts is a PLA pontoon-bridge units, rescue and relief work team open circuit equipment etc., but for the shallow long-pending fluidised form mud of rapid large-area district have still that engineering quantity is big, cost is high, inapplicable, difficulty that engineering machinery can't be marched into the arena, seriously hinder disaster relief process.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, engineering machinery construction passage in a kind of mud-rock flow fluidised form alluvial soil district is provided, it has been simplified mud-rock flow effectively and has remained fluidised form alluvial mud district road pavement program, improve express passway overlap joint efficient, be suitable for remaining the mud district at the shallow deposition rock glacier of large tracts of land and rapidly and efficiently build, modularization is assembled, manufacture process is simple and reliable relatively.
According to above technical purpose, the present invention will take following technical scheme:
A kind of mud-rock flow fluidised form alluvial soil district engineering machinery construction passage, described engineering machinery construction passage is spliced by plural passage module units, described passage module units comprises bearing unit, outsourcing base plate and supporting side walls, the outer bottom of described bearing unit covers wraps up in the outsourcing base plate, and supporting side walls is installed on the limit, two opposite sides of described bearing unit respectively, adjacent two bearing units connect by the rotation latch, then connect by the watertight rubber sheet between the two adjacent supporting side walls.
Described bearing unit comprises vertical load-bearing shaped steel and U-shaped shaped steel purlin frame, the bottom of U-shaped shaped steel purlin frame is installed on vertical load-bearing shaped steel by fastener, supporting side walls then is connected with U-shaped shaped steel purlin frame side arm, and the bottom of supporting side walls is installed on vertical load-bearing shaped steel by hinge simultaneously.
Described supporting side walls adopts the water proof composite board to be made.
Described U-shaped shaped steel purlin frame side arm and the bottom between by the support and connection of type frame.
The two ends of described supporting side walls are provided with the corner cut side, and the inclination alpha of described corner cut side is 60～75 °, and adjacent two supporting side walls are by riveting with the watertight rubber sheet on its corresponding corner cut side.
The seam outside of adjacent two bearing units covers sealing by the watertight rubber sheet of riveted joint.
According to above technical scheme, can realize following beneficial effect:
1, mud-rock flow fluidised form alluvial soil district's engineering machinery construction passage of the present invention adopts the modularization package technique, connect reliably, and the packaging efficiency height, each module is detachably classified and is stored transportation, is convenient to transition;
2, bearing unit connects by detachable Fixed latches, can rotate up and down; Seam between the supporting side walls adopts the watertight rubber sheet by the rivet rivet clasp, and stagnant water effect is better;
3, supporting side walls is Height Adjustable, its with bearing unit between be connected by built-in latch, erectility is sealing effectively, adjacent supports sidewall corner cut in advance forms the corner cut side, is convenient to the rotation of adjacent cells;
4, bearing unit connects with this, can need not to set in advance the fixed orientation anchor cable by overlapping assembling mode step by step to predetermined regional laying road, and device contacts to earth, and power transmission is firm, avoids the poor stability weakness of floating box type passage.
The present invention forms vertical passage by the fixedly connected bearing unit of hinge, and lays the watertight rubber sheet at seam crossing; The bearing unit dual-side is established the supporting side walls that is used to stop muddy water, and water and soil pressure transmits balance by shaped steel purlin frame on the supporting side walls; After bearing unit series connection overlap joint is shaped, fill sandstone material leveling, lay the smooth express passway device of the compound basal plane road surface that is open to traffic, therefore, the present invention is applicable to the lapped layup work of the shallow deposition of large tracts of land slurry district express passway, for the smooth expansion of rescue and relief work provides prerequisite.Speed passage lap device adopts the assembling of standard package modularization, easy to be quick, connect reliable, overlap joint packaging efficiency height, need not to set in advance the anchor cable location, independently the selector channel direction can be opened up one and is suitable for the rapid construction passage that middle-size and small-size construction machinery passes through fast in mud severe siltation zone.
