Many bridges of the present invention static cone penetration equipment and many bridges static cone penetration test method are because a test process can carry out the test of bulk items, and the underground rock-soil layer information that can obtain to enrich has widely and uses.
Application such as the wave velocity testing aspect, the prospecting of general highrise building place need to be carried out shear wave velocity measurement to the place rock-soil layer, this method only need be loaded onto wave speed of the earthquake sensor catcher, can finish simultaneously the test to the shear wave velocity of rock-soil layer, a static sounding process had both obtained the doube bridge data, obtain again the velocity of wave data, greatly increased the efficient of exploration, reduced exploration cost.
The for another example application of underground shooting, the image informations such as the color by rock-soil layer in the image of analyzing rock-soil layer under the different depth, particle, composition, hole, moisture content, we can judge the proterties such as the naming of rock-soil layer, color, state, with the method for the probing of fetching earth the ground core are got and are carried out the naked eyes analysis on the ground and reach same effect and purpose.That is to say that the image by underground shooting can carry out the layer by layer division of position of ground and the judgement of state, and a layer position dividing precision drills far above tradition, and can observe the situation of the underground water that the tradition probing can't observe.The method is specially adapted to complicated rock-soil layer prospecting, and for example the prospecting of solution cavity area can disclose very careful underground scene.The underground camera function convenient test of static cone penetration equipment of the present invention is quick, and efficient is high, and cost is low, and this cone penetration method can replace traditional core drilling fully.
