Abstract
The invention relates to an underground water detection method which comprises the steps of (1) horizontally drilling by using a Luoyang shovel to obtain a front soil sample; (2) measuring the water content w of the soil sample obtained by drilling in a laboratory; and (3) predicting the underground water content of the front soil according to the measured water content of the soil sample. The method is simple in technology and easy in construction, and the front underground water detection work can be conveniently and rapidly realized.
Description
Technical field
The present invention relates to technical field of building construction, particularly a kind of underground water detection method.
Background technology
In modern construction of underground structure is built, the difficulty in most construction is all that the direct or indirect factor by underground water is caused, as piping, and stream soil etc.It is original structural that the existence of water has destroyed the soil body, reduced the effective unit weight of the soil body and c, ∮ value, reduced native intensity, thereby brought great difficulty to construction.Therefore, in construction early stage and work progress, the detection of underground water, ejectment and shutoff work are very important.Reasonably groundwater treatment mode not only can bring great convenience to construction, simultaneously also can water conservation and local natural ecological environment.
The geophysical prospecting method such as the multiplex geological radar of detection method of current underground water, there is following shortcoming in these methods:
1, also need not do debugging and the preliminary work of instrument before using, therefore use more loaded down with trivial detailsly, and not be suitable for the soil body under various environment.
2, detection principle more complicated, cannot survey the place ahead underground water distribution situation intuitively, fast.
Summary of the invention
In order to solve underground water in existing situation, survey complicated problem, the embodiment of the present invention provides a kind of underground water detection method, and the method technique is simple, be easy to construction, can realize quickly and easily the detection operations of the place ahead underground water.
As above design, technical scheme of the present invention is: a kind of underground water detection method, is characterized in that: comprise the steps:
1. Luoyang Spade horizontal drilling, obtains the place ahead soil sample;
2. the water percentage w of the experimental determination boring soil sample of obtaining;
3. according to measuring Water Content Tests in Soil Samples, predict the contained groundwater condition of the place ahead soil body.
Above-mentioned steps 1. soil sampling diameter range between 10 to 20cm.
Above-mentioned steps concrete grammar is 3.:
Water percentage w according to the place ahead soil sample, can first divide soil sample:
When w<10%, think that soil sample is drier, the place ahead is not containing underground water;
When 10%≤w<20%, artificial soil sample is moistening a little, and the place ahead has contained underground water less, can process according to construction concrete condition;
When 20%≤w<30%, soil sample is moist, and the place ahead also has a certain amount of underground water, should note taking corresponding measure to carry out shutoff in construction;
When w >=30%, think that soil sample is in state of saturation, a large amount of underground water is contained in the place ahead.
The present invention has following advantage and good effect:
1, economical convenient, applicability is wide.With respect to geological radar, the cost of Luoyang Spade is cheap more economically, and debugging and the preliminary work of before use, also it goes without doing instrument are therefore very convenient to use.And be applicable to the soil body under various environment.
2, fast direct.Luoyang Spade coring is very quick.And the distribution situation of underground water can directly reflect by the soil body in the soil body of the place ahead.If experienced, even can directly according to hore plug, " read " the place ahead water status.
Accompanying drawing explanation
Fig. 1 is construction process figure of the present invention.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with instantiation, embodiment of the present invention is described further in detail.
This method first is on probation is in the construction process of Beijing Metro twin-well station.While building, adopted the mode that geological radar is combined with Luoyang Spade to survey the place ahead underground water, obtained good effect, the detection simultaneous verification of geological radar Luoyang Spade visit the accuracy of water.
The first step: soil sample is obtained in boring;
On subway tunnel face, adopt Luoyang Spade boring, horizontal direction drills through the place ahead soil sample.Approximately 2 to 3 meters of left and right of the desirable front of tunnel heading of the degree of depth that fetches earth.The diameter fetching earth is very important, if the diameter that fetches earth is too small, has influence on quality of soil sample, can not react the place ahead soil sample situation comprehensively; If fetch earth, diameter is excessive, to construction, makes troubles, and easily falls soil.In view of the soil sample diameter of triaxial test is 10cm, so as long as soil sampling is larger than 10cm.10 to 20cm all can.
Second step: the water percentage of experimental determination soil sample.
The method of Water Content Tests in Soil Samples and common style assay method are as good as.Can adopt oven drying method.The visible soil test books of being correlated with will not describe in detail herein.
The 3rd step: prediction the place ahead underground water distribution situation.
Water percentage w according to the place ahead soil sample, can first divide soil sample:
When w<10%, think that soil sample is drier, the place ahead is not substantially containing underground water;
When 10%≤w<20%, artificial soil sample is moistening a little, and the place ahead has contained underground water less, can process according to construction concrete condition;
When 20%≤w<30%, think that soil sample is moist, the place ahead also has a certain amount of underground water, should note taking corresponding measure to carry out shutoff in construction;
When w >=30%, think that soil sample is in state of saturation, a large amount of underground water is contained in the place ahead, carries out possibly the measure that ejectment and shutoff combine in construction.
The embodiment of the present invention is reasonable in design, and technique is simple, is easy to construction, utilizes this technology simple, convenient, realizes efficiently the detection operations of the place ahead underground water, for construction, makes guidance, guarantees the safety of construction of underground structure.And with respect to other geophysical prospecting method, detection principle is easily understood.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
