Description
Technical Field
The invention relates to the field of geological disaster prevention and control, in particular to a device for treating landslide by using microwaves.
Background
The landslide is a natural phenomenon that soil or rock mass on a slope slides downwards along the slope integrally or dispersedly under the action of gravity along a certain weak surface or a weak zone under the influence of factors such as river scouring, underground water activity, rainwater immersion, earthquake, artificial slope cutting and the like.
The bottom of the landslide body is provided with a soil layer with high water content, the friction coefficient is reduced after water is contained, and the main reason for forming the landslide is that two methods are mainly used for treating the landslide at present:
the first is a method for fixing a landslide body by building a structure and blocking soil body movement, such as a method for fixing by driving anti-slide piles, and the anti-slide structure (CN201720636550.1) for governing large landslides by multiple rows of anchor cables and multiple rows of anti-slide piles; a method for fixing a side slope, in particular to a landslide control side slope supporting structure (CN 201821256125.0); a retaining wall fixing method, a retaining wall construction method with slide-resistant piles for landslide control (CN 201810843219.6).

The method for fixing the landslide body by adopting the structure does not eliminate key risk factors causing landslide, has great danger in developing construction activities on the landslide body, and has high construction cost. The drainage method is a passive drainage method for reducing the water content of the sliding surface, the water content is reduced a little and uncontrollable, only the function of partially reducing the friction coefficient can be achieved on the sliding surface, and the effect is not obvious enough.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.
In the present application, each term has a meaning generally understood in the art, unless otherwise indicated or a different meaning can be derived from the context.
The application discloses a method for reducing the water content of a soil layer on a sliding surface in a microwave drying mode to prevent and control landslide on one hand. The term "slip plane" in this application refers to the interface between the body and the wall of the landslide, either between layers of soil at a particular depth or at the interface between a layer of soil and a layer of rock. The soil body or rock body is influenced by factors such as river scouring, underground water activity, rainwater soaking, earthquake, artificial slope cutting and the like, and integrally or dispersedly slides along the sliding surface under the action of gravity, so that landslide is caused.
The soil layer on the sliding surface has rich water content, and under the conditions of rainfall, underground water burst, surface runoff infiltration and the like, the soil layer on the sliding surface is sometimes in a saturated or supersaturated state, and sometimes even a water accumulation layer appears below the sliding surface, so that the shear strength of the soil layer is greatly reduced, and a soft surface or a soft zone which is easy to slide is formed. Therefore, the method for rapidly reducing the soil moisture content on the sliding surface is the key for fundamentally preventing and controlling the landslide. When governing mountain landslide, the slip surface soil layer depth's is confirmed and is helped the continuous monitoring to landslide risk factor to provide the basis for confirming reasonable treatment scheme. The determination of the sliding surface can be based on geological data of the area, or based on landslide disaster recorded data, and can also be based on the distribution of field detection soil moisture in the vertical direction to determine the soil layer depth of the sliding surface.
Those skilled in the art understand that moisture in soil includes free water and bound water, and that physical drainage measures can only drain free water, while a large amount of bound water can stay in soil pores. Under specific environment, the free water is not enough to be discharged to ensure the stability of the soil body, and additional energy is required to be provided to evaporate the combined water in the soil so as to reduce the soil moisture to a safe level. The microwave is used as an energy source, so that the soil moisture is evaporated and escaped, and the purpose of rapidly reducing the moisture is realized.
Specifically, the application provides a method for treating landslide by using microwaves, which comprises the following steps:
installing equipment: installing a landslide treatment device on the slope surface, wherein the landslide treatment device comprises a microwave generator and a soil moisture content detector;
microwave treatment: and emitting microwaves to the sliding surface by adopting a microwave generator, measuring the soil moisture content of the sliding surface by adopting the soil moisture content detector, and stopping emitting the microwaves when the soil moisture content is reduced to a preset value.
In some specific embodiments, if the slope surface area is large, the slope surface may be divided into a plurality of areas, the treatment of one area is completed according to the above steps, then the microwave generator is moved to an adjacent area, microwaves are emitted to the sliding surface of the adjacent area, the soil moisture content of the sliding surface of the adjacent area is measured by using the soil moisture content detector, when the soil moisture content is reduced to a preset value, the emission of microwaves is stopped, the treatment of the adjacent area is completed, and the microwave generator and the soil moisture content detector are continuously moved to the next area for microwave treatment until the soil moisture content of the sliding surface of the whole slope surface is reduced to a preset value, so as to complete landslide control.
The microwave in the present application means that the wavelength is between 1mm and 1m, and the frequency is 3.0 x 102～3.0×105The microwave is an electromagnetic wave of MHz, the microwave possesses the characteristic such as the oscillation cycle that the electric field is peculiar is short, the penetrating power is strong, can produce the specific effect with the material interaction, wet supplies are in the very short microwave high-frequency electric field of oscillation cycle, the water molecule in its inside can polarize and arrange neatly along the direction of the microwave electric field, then rotate with the alternating change of the high-frequency alternating electric field direction rapidly, and produce violent collision and friction (can reach hundreds of millions of times per second), a part of microwave energy of result turns into the kinetic energy of molecule, and show in the form of heat, make the temperature of water rise and leave the supplies, thus make the supplies dry. That is, after the microwaves enter the material and are absorbed, their energy is converted into heat energy inside the dielectric of the material. Therefore, the microwave drying is a drying mode which uses electromagnetic waves as a heating source and the dried material is a heating body. Is currently used in China for industryThe common frequencies of microwave drying and heating are 915MHz and 2450 MHz. In the landslide control method disclosed in the present application, a person skilled in the art can select and set the microwave frequency and power according to the shape, material, and water content of the material to be heated.
The technical personnel in the field understand that when the substance is radiated by microwave, the polar molecules which are originally in a random distribution arrangement state inside generate violent vibration under the influence of an alternating electromagnetic field and are oriented to the polar distribution arrangement state of the microwave electromagnetic field, and because the molecule rotation is interfered by the molecule irregular thermal motion and the intermolecular force existing inside the substance at any moment, the molecules generate mutual collision and friction, the absorbed microwave energy is quickly converted into the molecular thermal motion kinetic energy to be expressed in a thermal form, so the temperature of the medium is continuously increased.
For soil layers with potential landslide risks, the method has the key points of quickly reducing the soil moisture content of the sliding surface, improving the friction coefficient among soil layers, improving the soil hardness and preventing relative sliding among the soil layers and internal deformation of soil bodies. The aim can be achieved by removing water in the soil layer on the sliding surface by microwaves, and the method has great advantages and mainly embodies the following two aspects:
first, the transmission properties of microwave radiation rapidly conduct energy to deep soil. The traditional heating modes such as conduction, convection and heat radiation are external heating processes for transferring heat from the outer surface of the material to the inner surface, and the traditional heating modes such as conduction, convection and heat radiation take longer time to complete substances with low heat conductivity such as soil. The microwave has transmission property, heat is not transmitted from outside to inside, but directly acts with water molecules in the microwave and is quickly converted into heat energy, and the time for heating, warming and drying dehydration is shortened.
Secondly, the heat conducted to the deep soil is rapidly absorbed by the moisture of the slip surface of the soil layer at a specific depth. Since water is a typical polar molecule and is the medium with the best effect of absorbing microwaves, all materials containing moisture can absorb microwaves. In a specific depth, the higher the moisture is, the higher the landslide risk of the soil layer is, but the higher the capability of the soil layer for absorbing microwave radiation is, the microwave drying concentrates energy on the soil layer with the highest sliding risk, the temperature of the moisture in the soil layer is gradually increased after the moisture absorbs microwave energy, and finally the moisture is dispersed in the form of steam, so that the aim of drying and dewatering is fulfilled.
In some embodiments, the soil moisture content is detected by any one of the following detection methods: observation, resistance, neutron, gamma-ray, standing wave ratio, time domain reflectometry, and high frequency oscillation (FDR). The observation method is a simple measurement method, the soil moisture content is roughly estimated by analyzing the conglomeration of the target soil, the result accuracy is low through the observation method, and the landslide control method has guiding significance. The resistance method is to measure the water content of soil by utilizing the correlation between the electric conductivity of a porous medium and the water content and dielectric constant of the porous medium. The neutron method is a method for determining the water content of the soil according to the characteristic that hydrogen atoms in the soil water can rapidly reduce the speed of fast neutrons so that the fast neutrons are converted into slow neutrons (thermal neutrons), and is simple and rapid in measurement, high in precision and not greatly influenced by temperature and pressure. The basic principle of the gamma-ray method is that when gamma-rays emitted from radioactive isotopes penetrate the soil, the attenuation of the gamma-rays increases as the wet volume weight of the soil increases, and the moisture content of the soil is measured. The standing wave ratio method is characterized in that a deterministic single-value polynomial relation exists between the soil moisture content and the soil dielectric constant, namely the soil moisture content is obtained by measuring the soil dielectric constant, the standing wave ratio method is high in measuring speed, does not damage the soil, can be used for long-term fixed-point monitoring, outputs signals which are electric signals, and is easy to record, process and control. Time Domain Reflectometry (TDR) is also a method of obtaining soil moisture content by measuring the dielectric constant of soil. The TDR method has the advantages of high measuring speed, simple and convenient operation, high accuracy which can reach 0.5 percent, continuous measurement, capability of measuring the surface moisture of the soil and the moisture of a section, capability of being used for handheld real-time measurement and remote multi-point automatic monitoring, and easiness in processing of measured data. The high frequency oscillation (FDR) method is derived from TDR, is cheaper than TDR, has shorter measurement time, has high measurement precision after specific soil calibration, can simultaneously measure multiple depths without limiting the shape of a probe, and is easier to realize data acquisition. In the landslide control method disclosed in the present application, a person skilled in the art can select one or more of the above-mentioned measuring methods to measure the soil moisture according to different conditions of the control area, and determine whether to stop transmitting microwaves according to the measurement result.
In some embodiments, the preset value is at least one selected from the group consisting of: 40%, 30%, 20%, 10%. The landslide risk is closely related to soil texture, soil water content and slope gradient, reasonable preset values are selected according to different slope gradients, microwave emission is stopped when the soil water content is reduced to the selected preset value, the treatment cost can be reduced to the maximum extent while landslide of the mountain is effectively prevented, generally speaking, for the slope with small gradient, a higher value can be selected as the slope with small gradient enables the mountain to form a relatively stable structure, the landslide risk is lower, the stable structure can be still kept when the soil water content on the sliding surface is higher, otherwise, for the slope with large gradient, a lower value should be selected as the slope with large gradient means that the risk of the mountain sliding on the sliding surface is large, and only the soil water content on the sliding surface is reduced to the lower preset value, the friction between the soil particles can be increased, thereby maintaining the stability of the mountain. For example, for a slope with a slope gradient between 10 and 30 degrees, a preset value of 40% is chosen, for a slope with a slope gradient between 30 and 50 degrees, a preset value of 30% is chosen, for a slope with a slope gradient between 50 and 70 degrees, a preset value of 20% is chosen, and for a slope with a slope gradient between 70 and 90 degrees, a preset value of 10% is chosen. The selection of the preset value can be applied to most of mountain landslide disaster-prone areas, and the method is a general method capable of quickly determining the preset value. Those skilled in the art can also select a suitable preset value according to the influence of other relevant elements in a specific area, such as soil type and vegetation coverage.
In some embodiments, the method further comprises the following pretreatment steps: and (3) adopting a waterproof measure to the upper part of the slope surface and the side slope to avoid the increase of the soil moisture content of the landslide surface and/or reducing the soil moisture content of the sliding surface by a physical drainage measure. In certain circumstances, the accumulation of moisture on the sliding surface may be due to the penetration of ambient moisture, which may be beneficial in combination with water-proofing prior to microwave treatment. Under some specific environments, the soil on the sliding surface has extremely high water content or water accumulation layers and the like, and good effects can be generated by combining physical drainage measures with microwave treatment. Of course, the pretreatment steps are not essential to the microwave treatment method disclosed in the application, but the combined use of various measures can achieve the best treatment effect at the lowest cost by combining the construction environment under the specific environment.
In some embodiments, the method further comprises the post-processing step of: and one or more measures of piling, retaining wall and slope maintenance are combined to further control the occurrence of landslide. The microwave treatment has the advantages of accuracy, high efficiency and timeliness in preventing and treating landslide, and in areas where seasonal geological disasters frequently occur or areas where landslide directly affects life and property safety of people, such as slopes of roads, water channels, river channels and adjacent areas of houses, after emergency danger is eliminated by microwave treatment, one or more measures in piling, retaining walls and slope maintenance are combined for post-treatment, so that landslide disasters can be further controlled. Of course, after these post-treatment measures are taken, the microwave remediation method disclosed herein may still be employed in emergency situations.
In some embodiments, the method further comprises the post-processing step of: plants are planted on the slope and/or mulch is added, under certain specific environments, landslide disasters are caused by the fact that the slope is not covered by vegetation, plants are planted on the slope or mulch films are covered on the slope, and therefore the internal aggregate structure of soil is improved, soil stability is improved, a large amount of water is prevented from permeating, and landslide is further controlled to occur.

In some embodiments, the landslide management device further comprises a grade detection component. The grade detection component is not required and in some embodiments, the grade is often the underlying data obtained by the geological exploration job in the geological exploration. In the case where the specific gradient data is lacking, the gradient detection means may also be employed to perform the detection of the gradient.
