Abstract

The utility model discloses a doublet sand resistance structure for road protection in a sandy area. The doublet sand resistance structure comprises base-layer high vertical sand-protecting barriers vertically arranged on the ground on one side of a roadbed, wherein the base-layer high vertical sand-protecting barriers are arranged in two streaks at intervals. The base-layer high vertical sand-protecting barriers in each streak are embedded in base-layer sand beams. Two sides of the base-layer sand beams respectively form slopes with a slowly reduced gradient. Upper-layer sand-stabilizing meshes or neutral vertical grid sand-protecting barriers are arranged on top ends of the base-layer sand beams. Upper-layer sand beams are covered on tops of the base-layer sand beams and two sides of each upper-layer sand beam respectively form slopes with a slowly reduced gradient. The upper-layer sand stabilizing meshes or neutral vertical sand-protecting barriers are embedded in the upper-layer sand beams. The doublet sand resistance structure for the road protection in the sandy area reduces the amount of follow-up maintenance work and guarantees normal use of roads in the sandy area.

Description

The husky structure of bimodal resistance that is used for dust storm area road prevention

Technical field

The utility model relates to a kind of husky structure of bimodal resistance that is used for dust storm area road prevention.

Background technology

Railway or highway are through dust storm when area, and the grains of sand are often blown on railway or the highway by wind, on railway, flow or blow over and cover completely railway roadbed when serious, when slight plate knot of ballast bed are followed the string, and threaten railway operation, and highway is attend regular meeting has long-pending husky blocking-up traffic.Defending and controlling sand is a global problem; China is one and endures one of big country of sand damage to the fullest extent, in desert area, because the restriction of weather conditions and water resources condition; Especially the desert area annual rainfall in Xinjiang and Inner Mongol is merely 20～30 millimeters; Build railway or highway in these areas, plant protection does not have available water resource, and the pipeline diversion needs a large amount of investments.Therefore, how adopting engineering resistance sand to fix the sand measure, make railway or highway avoid the harm of dust storm in these areas, is the target that the Rail Highway builder pursues.

So-called dust storm is meant the phenomenon that the moving grains of sand of wind move near ground.Usually employing is fixed the sand and is hindered husky measure, i.e. the measure of the grains of sand on the fixed bottom boundary is for fixing the sand measure, and the measure that the grains of sand in the outside, prevention guard plot get into is for hindering husky measure.Stop that outside dust storm is at present used to be PE net sand-protecting barrier, bury spacing on ground underground and be 3 meters column, middlely connect with iron wire, on iron wire, hang the husky net of PE, utilize the PE net to come catch blowing sand, weaken wind speed, the grains of sand are before and after sand-protecting barrier under the stop.Because PE sand-protecting barrier net is plastic products, under the external force effect of exposing to the weather, aging speed is very fast, and application life is short, all can not use after general 3～5 years, when the density of contained sand is big in the wind on the other hand.Dust storm is flowed or blow over and cover completely sand-protecting barrier several times, loses the husky function of resistance.After sand-protecting barrier is flowed or blow over and cover completely, need to remove the long-pending sand of sand-protecting barrier front and back, sand-protecting barrier is basseted continue to play a role.And sand-protecting barrier aging after, then can not continue to use, need purchase new sand-protecting barrier and hang on iron wire and the column.Operation so repeatedly, not only investment increases, and the maintenance expense continues to increase, and makes the husky facility of resistance maintain the category of temporary works, can not reach the husky effect of permanent resistance.

Summary of the invention

The purpose of the utility model is to provide a kind of husky structure of bimodal resistance that is used for dust storm area road prevention, can make external wind sand blocking in the outside, husky peak, greatly reduces the follow-up maintenance workload, guarantees the normal use of dust storm area road.

The purpose of the utility model is to realize like this; A kind of husky structure of bimodal resistance that is used for dust storm area road prevention; Be included in the basic unit's high vertical sand barrier that vertically is provided with on the roadbed one side ground; Basic unit's high vertical sand barrier is divided into spaced apart twice, and each road basic unit high vertical sand barrier all is embedded in the husky beam of basic unit, and basic unit Sha Liang both sides constitute the slow side slope of falling that tilts respectively; The top of the husky beam of basic unit be provided with the upper strata Sand-fixation net or in vertical grid sand-protecting barrier; Cover on the end face of the husky beam of basic unit upper strata Sha Liang is being set; The both sides of upper strata Sha Liang constitute the slow side slope of falling that tilts respectively, said upper strata Sand-fixation net or in vertical grid sand-protecting barrier be embedded in the Sha Liang of upper strata.

The utility model adopts the husky structure of bimodal resistance; Through with husky sand control measure; Can make external dust storm be blocked in the outside, the husky peak of twice, need not to change sand-protecting barrier or husky net, thereby greatly reduce the follow-up maintenance workload; Eliminate the phenomenon that dust storm district railway line or identitypath are buried by drift sand, guaranteed the normal use of dust storm area road.

Description of drawings

To combine accompanying drawing that the utility model is done further detailed explanation below.

Fig. 1 is the perspective view of the utility model.

The specific embodiment

A kind of husky structure of bimodal resistance that is used for dust storm area road prevention; As shown in Figure 1; Be included in the basic unit's high vertical sand barrier 5 that vertically is provided with on the roadbed 7 one side ground, basic unit's high vertical sand barrier 5 is divided into spaced apart twice, and twice basic unit high vertical sand barrier 5 all parallels with roadbed 7.Each road basic unit high vertical sand barrier 5 all is embedded in the husky beam 6 of basic unit, and basic unit husky beam 6 both sides constitute the slow side slope of falling that tilts respectively; The top of the husky beam 6 of basic unit be provided with upper strata Sand-fixation net 2 or in vertical grid sand-protecting barrier 4; Cover on the end face of the husky beam 6 of basic unit upper strata Sha Liang 3 is being set; The both sides of upper strata Sha Liang 3 constitute the slow side slope of falling that tilts respectively, said upper strata Sand-fixation net 2 or in vertical grid sand-protecting barrier 4 be embedded in the upper strata Sha Liang 3.In the height of vertical grid sand-protecting barrier 4 be 0.6 meter, the height of basic unit's high vertical sand barrier 5 and upper strata Sand-fixation net 2 is respectively 1.5 meters.Cover on the end face of upper strata Sha Liang 3 the compound rock beam 1 of cellular type is being set.The end face of upper strata Sha Liang 3 is 3-5 meters apart from the height on ground.The utility model adopts the husky structure of bimodal resistance, can make external wind sand blocking in the outside, husky peak, greatly reduces the follow-up maintenance workload, guarantees the normal use of dust storm area road.
