Description
Technical field
The utility model belongs to subgrade in salty soil zone technical field of construction, and in particular to a kind of salt discharge roadbed.
Background technology
Salinized soil refers to the soil containing certain salinity, relative to the salinity and mineral being rich in earth's surface, institute in salinized soil
The salinity and mineral contained, which is above standard, either contains certain or several special salinities.Definition to salinized soil is expressed as：Rock
Stone has a small amount of lyotropic salt in efflorescence and separated, and common lyotropic salt mainly has villaumite, sulfate and carbonate.
These readily soluble salts permeate the ground in the presence of water is dissolved in underground water, and underground water can be gradually increasing because of capillarity, when it
It is increased to earth's surface or during close to earth's surface, the salt branch in water is separated due to evaporation is gathered in earth's surface, is formed easy
The content of dissolved salt is more than 0.5% soil, referred to as salinized soil.
The dilatancy of lyotropic salt can cause the salinized soil soil body volume containing lyotropic salt that acute variation occurs, to saline soil area
Road hazards are serious.The temperature sensitivity of sulfate is stronger, is easy to that crystallization and dehydrating phenomena, knot occurs under the influence of the temperature
Volume-diminished when volume increases and is dehydrated when brilliant.This results in the soil body containing sulfate, in the arid area that temperature difference per day is larger,
Because sulfate volume when contracting when it is swollen, soil structures are loose, when winter temperature declines by a big margin, produce substantial amounts of crystallization and lead
Cause the violent swelled ground of the soil body in sulphates content when within 2%, it is considered that the dilatancy of crystal salt to soil harmfulness compared with
Small, when this content higher than 2%, its swell increment increases sharply, caused harm also rapid increase.Carbonate absorption sun from
Son is had an effect in the presence of water with colloidal solid, formation around colloidal solid and clay particle is combined water film, is caused
Cohesive force between soil particle reduces and soil expansion.
Salinized soil can not only expand in the presence of water, and because readily soluble salt is highly soluble in water, therefore ground can also be
And occur to sink.When salinized soil and loess have similar structures, i.e. silt content>45%, porosity>When 45%, have certain
Settlement by soaking.The optimum density of soil can be gradually smaller with the increase of salt content in soil, and exceedes certain limit in salt content
When, soil is extremely difficult to optimum density, and so as to cause the soil body to be extremely difficult to defined compactness, such case is easy to produce inequality
Even sedimentation.With the increase of water content in subgrade soils and the rise of temperature, dissolving of the water to soluble-salt in soil and work is moved
With enhancing, roadbed is easily deformed in this case.During roadbed produces salt corrosion, Salts In Salt-affected Soil dissolves simultaneously
Being taken away by moisture causes subgrade strength to drastically reduce, and under external load or Gravitative Loads, sink deformation occurs.
Salinized soil is a kind of special soil, and environmental sensitivity is strong, and its engineering properties is understood the environment such as Sui Shui, heat and become
Change.The salt content of salinized soil is higher, and under the influence of moisture and temperature, different degrees of phase can occur for contained salt in soil
With the change of quantity, and salinized soil is set to show unstable engineering characteristic.This special engineering properties of salinized soil is in height
Salt content area can particularly have a strong impact on the stability and durability of roadbed in groundwater level region.
The content of the invention
The purpose of this utility model in providing a kind of road structure form that can exclude salinity in Salty Soil Subgrade in time,
Reduce the influence that salinity in ground migrates roadbed engineering quality upwards to greatest extent.
To achieve these goals, the utility model employs following technical scheme：A kind of saline soil area salt discharge roadbed,
It is included in longitudinal salt discharging pipe of roadbed metalling bottom setting and horizontal salt discharging pipe, and longitudinal salt discharging pipe is by upper half shell and lower half
Shell forms complete circular tube wall, and wherein lower half shell surface is complete, and upper half shell offers the hole through tube wall, longitudinal direction
Salt discharging pipe with horizontal salt discharging pipe is crisscross reticulates, horizontal salt discharging pipe is access to sump.Water in metalling can pass through hole
Arranged into longitudinal salt discharging pipe, then by horizontal salt discharging pipe to sump.
The gradient of the longitudinal slope and horizontal slope of longitudinal salt discharging pipe and horizontal salt discharging pipe and roadbed is consistent.
Longitudinal salt discharging pipe is arranged in metalling, away from 4.5~5.5cm of metalling bottom.
Sump is arranged on the outside of roadbed, and well room bottom absolute altitude is no less than 1m less than metalling.
Horizontal salt discharging pipe is connected with longitudinal salt discharging pipe by threeway or four-way pipe fitting.
Salt discharge roadbed in saline soil area of the present utility model, its reasonable in design and constructing operation is simple, can not only be effective
Ground reduces the level of ground water of roadbed, and can also alleviate salinity well with moisture to roadbed internal migration, carries to greatest extent
Durability of elevated formation level etc., it ensure that the running quality of road engineering during use.
The utility model has advantages below compared with prior art：
1st, the utility model is simple in construction, reasonable in design, and constructing operation is convenient.
2nd, the utility model alleviates the rise of roadbed level of ground water to roadbed by setting salt discharging pipe in roadbed metalling
Influence, reduce influence of the salinity with water translocation roadbed engineering quality to greatest extent.
3rd, by setting sump, the water that can effectively protect in metalling is discharged into sump the utility model at any time.
4th, of the present utility model practical, using effect is good, is easy to promote the use of.
