Description
Technical field
The utility model is related to side slope protection field, more particularly to a kind of expansive soil slope intelligent early-warning and guard system.
Background technology
With the rapid development of social economy, the engineerings such as civil engineering, water conservancy and traffic build to have obtained swift and violent development；But
In the construction of engineering, many inevitable disasters can be inevitably encountered, for example landslide disaster, especially in expansive soil slope
In construction, meet moat that must slide, Around resident personal safety and the economic development of locality bring huge loss.
Swelled ground is a kind of cohesive soil of particularity, and the sliding of slight slope, which is generally initially carried out by crack, to be caused, and is then gone here and there
Logical weak structural face forms continuous sliding surface, and then generates landslide.Swelled ground its with water swelling, the characteristic of dehydration shrinkage, when
When moisture content changes, volume can also occur significantly to change therewith immediately.Expansive soil slope has apparent seasonality,
In period in rainy season, the moisture content of soil property persistently increases in expansive soil slope, in turn results in soil softening, shearing strength is caused to drop rapidly
It is low.The moisture evaporation of soil property makes the moisture content rapid decrease of expansive soil slope in period of drought, expansive soil slope, this makes
Expansive soil slope surface generates rapidly fine cracks, these cracks are although small, but quantity is more, is distributed in each angle of slope surface
It falls, easy to form complicated Fracture Networks, at rainy season, rainwater is flowed by crack inside slight slope, and then softening inside leads to slight slope
The possibility for generating landslide increases.And in China, swelled ground distribution is very wide, and existing China is still in developing period, development
Dynamics goes from strength to strength with the development of the times, grand especially for realization " two 100 years " is planned, and realizes to shake off poverty and assault fortified position
The notable swell-shrink characteristic of great target, expansive soil slope brings serious security risk to the design of engineering, construction and operation.Cause
This, it is necessary to effectively monitoring and safeguard procedures are carried out to expansive soil slope.
From the point of view of the guard technology of current expansive soil slope, mainly there is physics for the protection of the side slope of swelled ground, changes
The method for strengthening such as, biology, commonly use at home the measure of processing expansive soil slope mainly it is artificial be laid with geomembrane, change fill out, supporting and retaining system
Deng, on the one hand primarily to avoid influence of the rainwater to swelled ground, on the other hand by huge retaining structure side slope into
Row supporting and retaining system further maintains the stability of side slope.But such methods are higher for the material requirements of laying, and soil removal enginnering amount is big,
Labour is big, and economy is undesirable.
Mainly based on personal monitoring, it is backward, data information to have technological means for traditional expansive soil slope monitoring
The features such as acquisition is difficult and the accuracy of acquisition of information is not high, the measuring point period is long, time-consuming and laborious, poor in timeliness.Personal monitoring
It can only find that the more apparent exception in side slope surface shows in the process, can not find side slope interior change situation, and artificial
Rugged environment may be met in monitoring process, while (heavy rain, earthquake) expansive soil slope easily occurs under rugged environment
Unstability and wreck, make monitoring that can not carry out.
The information for being disclosed in the background technology part is merely intended to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition has been existing well known to persons skilled in the art
Technology.
