Description

TECHNICAL FIELD

[0001] The utility model relates to the field of surveying technology, especially to a site positioning device of surface wave detector. BACKGROUND

[0002] The transient surface wave exploration is a kind of shallow geophysical exploration method, has the advantages such as simple, fast, economic, high resolution, intuitive result, applicable site small, has obtained the application in many fields, and has achieved good application effect.

[0003] Before the transient surface wave exploration, 12 or 24 detectors need to be installed and buried in the soil, and the contact between the detector and the soil is ensured.

[0004] The installation and burial of the detector mainly depend on a 6 to 8 cm long metal cone head, which is connected closely with the end of the detector through a threaded wire port. During installation, the operator needs to manually insert the metal cone head into the surface soil until the detector is securely buried, thereby completing the entire installation process. During surface wave exploration, the detector is connected to the host cable through a data line to complete data acquisition.

[0005] Problems existing in the existing installation and burial device:

[0006] 1. In the hard surface position of rock surface or concrete pavement, the metal cone head is difficult to insert into the ground surface, resulting in installation difficulty. If it is inserted after drilling a hole by impact drilling, it will cause damage to the rock surface or concrete pavement, increase workload, be low in efficiency, time-consuming and laborious, and be limited by the power environment.

[0007] 2. In the hard soil surface, the metal cone head is difficult to insert into the ground soil, and the insufficient insertion depth may also cause the detector to loosen or tilt, so that the detector is separated from the ground and cannot fully receive the seismic wave signal, affecting the exploration effect.

[0008] 3. The contact area between the metal cone head and the ground soil is limited, which may cause poor coupling effect between the detector and the ground, affecting the reception and recording quality of the seismic wave. As described above, the method of installing and burying the detector by relying on the metal cone head has many drawbacks in the hard surface such as rock surface, concrete pavement and hard soil surface.

[0009] 4. During surface wave exploration, each detector needs to be connected to the host cable through its dedicated data line. However, when collecting these detectors after the surface wave exploration is completed, the data lines are often disorganized, entangled or knotted, which not only brings inconvenience to storage, but also may affect the service life of the data line and the smooth use of the next exploration.

[0010] Based on this, this utility model designs a site positioning device for a surface wave detector to solve the above problems. Utility Model Content
