Description
Technical field:
The present invention relates to road performance technical field, particularly a kind of collapsible loess waterproofing performance of roads layer laying apparatus.
Background technology:
Collapsible loess is a kind of under drying regime, has higher-strength and comparatively low compressibility, meets a kind of Special Rock at certain External Force Acting or intensity rapid drawdown under Gravitative Loads after water.Its soil property is comparatively even, short texture, pores'growth, in its forming process, sufficient pressure and suitable humidity often can not possess simultaneously, cause the densification of soil layer not good enough, close to the soil layer on 2 ~ 3 meters, earth's surface, affect by Atmospheric precipitation, generally there is the humidity of suitable densification, but it is heavy very little now to go up earthing, and soil layer can not get sufficient densification, just defines the collapsible loess of low humidity, high porosity, under natural moisture, compressibilty is lower, but when meeting water infiltration, deflection is large, there is the de-stabilise distortion that subsidence velocity is fast.Collapsible loess is distributed widely in the Loess Plateau such as China Gansu, Ningxia, Shaanxi and Shanxi.The engineering harm main manifestations of collapsible loess to highway engineering is the differential settlement after meeting water, causes highway pavement Large Area Cracking, sink, thus cause other secondary highway distresses, and the settlement by soaking of aggravation loess foundation, causes vicious circle further.So the construction quality of collapsible loess subgrade in highway engineering directly affects construction quality and operation later stage, maintenance project phase of whole highway.
When collapsible loess foundation carries out engineering construction, the harm because damp sink of foundation causes additional settlement may cause engineering must be considered, select suitable method for processing foundation, avoid or the saturated yielding of eliminating ground or the harm caused because of a small amount of saturated yielding.Complete highway for a build, cause saturated yielding to be pavement seepage or be side slope seepage, the control of pavement seepage can overcome preferably by adopting suitable proportioning and the grating grade of gathering materials.Get up then much more difficult for side slope seepage prevention, and engineering quantity and fund input are all very large, at present for the process of side slope seepage adopt repair the roads time integrated use change fill out, strong rammer, compacted, ground layer of soil or mixed lime and soil, native stake or the method such as lime soil pile, pile foundation, and adopt the process of clay parcel in embankment both sides side slope and top, prevent rainwater from infiltrating.For the process of II level above collapsible loess foundation as adopted ground layer of soil or mixed lime and soil, native stake or lime soil pile, pile foundation presoaking, clay parcel, have that workload is large, cost labour is many, large, long in time limit, high cost shortcoming is taken up an area in job site in various degree.
In order to solve above defect, devise a kind of new-type embankment structure, as shown in Figure 1, the banded waterproof film 91 with one fixed width is devised in road both sides, the loess formation 93 of roadbed 92 times certain depths completely cuts off with the loess formation 95 under side slope 94 by waterproof film 91, to stop the loess formation 95 of side slope 94 times high-moistures to seep water to loess formation 93 below roadbed 92, thus rainy season ponding is avoided to cause side slope seepage to produce settlement by soaking.
