Description
Technical field
The utility model relates to a kind of static sounding device, especially a kind of static sounding device for the detection of beach soft clay area pipeline.Be applicable in the beach weak soil to survey than the pipeline of Large Diameter Pipeline.
Background technology
Along with the develop rapidly of urbanization, the task that underground utilities are born seems and become more and more important, and ensures the normal operation of underground utilities, and is self-evident to the importance of people's normal life and production.Pipeline is surveyed and is comprised that metallic conduit is surveyed and nonmetal pipeline is surveyed, and detection method has magnetoelectricity mise-a-la-masse method, galvanic couple power inductive method, magnetic dipole inductive method, signal clamp method, very low frequency method, ground penetrating radar method, resistivity method, mise-a-la-masse method, Shallow Seismic Reflection Method etc.For the pipeline of unlike material, caliber and buried depth, can adopt different detection methods with the purpose of the pipelines that hits pay dirk.
Yet the pipeline for the beach soft clay area, especially adopt Directional Drilling to spread the nonmetal pipeline that buries, because buried depth is darker, the control well interval is far away, and beach saline-alkali ground is on the impact of electromagnetic wave attenuation, and geophysical method commonly used comprises that resistivity method, electromagnetic method, ground penetrating radar method etc. all are difficult to the Effect on Detecting that reaches desirable.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, provide a kind of simple in structure, easy to operate static sounding device that is used for the detection of beach soft clay area pipeline, the problem that is difficult to survey to solve the darker pipeline of beach soft clay area buried depth.
The technical scheme that the utility model adopts is: a kind of static sounding device for the detection of beach soft clay area pipeline, this device comprises pedestal, and be installed on oil gear on pedestal, the pedestal center arranges the sleeve pipe that vertically passes pedestal, plug-in mounting feeler lever in sleeve pipe, the described oil gear of feeler lever upper end connection, feeler lever lower end sensor installation and cone point probe, described sensor connects quiet spy microcomputer through data line, it is characterized in that: the described cone point side of popping one's head in evenly arranges some bar shaped contacts.
The cutting edge of a knife or a sword mouth of described bar shaped contact is perpendicular to the ground.
Described bar shaped contact is steel matter.
Described bar shaped contact has 4, is cruciform and arranges.
The beneficial effects of the utility model are: the utility model utilizes pipeline in the static sounding penetration process and encloses the poor embedding location of coming the inverting pipeline of static point resistance between mud, solved the beach soft clay area, geophysical prospecting method can't detect a detection difficult problem of burying darker nonmetal pipeline.

Embodiment
The present embodiment is a kind of home position testing method---the Using Cone Penetration Test of pipelines, utilizes pipeline in the static sounding penetration process and encloses the poor embedding location of coming the inverting pipeline of static point resistance between mud.As shown in Figure 1, this device comprises pedestal 1, and the oil gear on installation and pedestal 6.Wherein the center of pedestal 1 is provided with the sleeve pipe 2 that vertically penetrates this pedestal, sleeve pipe 2 plug-in mounting feeler levers 3.Feeler lever 3 upper ends are connected with oil gear 6, and oil gear 6 drives feeler lever 3 straight up or moves downward; Feeler lever 3 lower end sensor installations 9 and cone point probe 4, this sensor 9 is electrically connected to quiet spy microcomputer 8 through data line 7.As shown in Figure 2 and Figure 3, in the side of cone point probe 4,4 bar shaped contacts 5 are set evenly in the present embodiment, are cruciform and arrange, the face at bar shaped contact 5 places and cone point 4 axis of popping one's head in are parallel.The purpose that increases bar shaped contact 5 is in order to enlarge the feeler inspection area, to eliminate and explore the blind area, increasing work efficiency.
In the present embodiment, the concrete construction method of pipelines is as follows:
1, at first process the bar shaped contact 5 of suitable length, and assemble with the cone point probe 4 of static sounding device, be assembled into cruciform;
2, simultaneously, comprehensively determine the exploratory spot spacing according to processing bar shaped contact 5 length and pipeline 10 diameter, to guarantee all standing to carry out feeler inspection in the survey line scope;
3, carry out feeler inspection in the exploratory spot position, utilize oil gear 6, by feeler lever 3, with bar shaped contact 5 and cone point probe 4 vertical injection soil layers; Simultaneously, the sharp data of cone are real-time transmitted to the quiet spy microcomputer 8 on ground by sensor 9 and data line 7.
4, in penetration process, the static point resistance of observing the reflection in real time of quiet spy microcomputer 8 constantly changes, and controls penetrating speed, and comprehensively determines depth of penetration according to the sudden change situation of static point resistance and the roughly buried depth of pipeline 10, finally finds out the particular location of pipeline 10.As shown in Figure 4, P01 ~ P05 represents respectively the static cone sounding curve figure of continuous 5 exploratory spots, at the visible P02 ~ P04 in the bottom of curve, the sudden change of obvious static point resistance having occured with respect to P01 and P05, extremely can interpret this as the position that pipeline buries according to pipeline and the resistance that encloses between mud.
