The utility model relates to an utensil technical field for the geotechnical engineering especially relates to a geotechnical investigation machines.

Background

In the engineering geology and hydrogeology exploration process, the temporary water level observation and the long-term water level monitoring of the underground water in the field are one of common exploration projects, and the method has important significance in the influences on engineering construction such as dynamic evaluation of the underground water, foundation pit anti-floating and the like. For underground stagnant water and diving, a common investigation mode generally adopts a special monitoring hole for monitoring.

In order to obtain the monitoring hole, a geological drilling machine is generally adopted for hole forming, then whether a well pipe is installed and manufactured, a filter material is backfilled or other reinforcing constructions are carried out on the monitoring hole or not is selected according to field requirements, and then water level measurement is directly carried out or carried out in the water pumping process or after water pumping.

In the prior art, an exploration tool integrating drilling and measurement is available, and the tool mainly comprises a base, a drilling part installed on the base, and a measurement part installed on the base. When the underground water level measuring device is used specifically, the base is located on the site firstly, then the monitoring hole is drilled by the drilling component, finally the measuring component releases the sensor into the monitoring hole, and the underground water level condition is obtained according to the released distance before the sensor enters water.

Further optimize the structural design of the machines and tools for water level monitoring to make it can better apply to the geological survey, undoubtedly have important meanings to geotechnical survey engineering etc..

SUMMERY OF THE UTILITY MODEL

To the structural design of the further optimization of the machines that are used for water level monitoring that provides to make its can be better apply to the geology reconnaissance, undoubtedly have important technical problem to geotechnical reconnaissance engineering etc. the utility model provides a geotechnical reconnaissance machines, the reconnaissance machines that this scheme of adoption provided are convenient for change or adjust the length of drilling rod according to particular case, so that its different drilling depth of adaptation that can be better.

The utility model provides a geotechnical investigation machines and tools solves the problem through following technical essential, a geotechnical investigation machines and tools, including the bottom plate, install drilling part and the detection subassembly on the bottom plate, drilling part includes the sleeve, sets up the elevating gear in the sleeve inside, with the drilling module that elevating gear links to each other, drilling module carries out drilling feed motion under elevating gear's effect, drilling module forms the detachable relation of connection through first extension arm and second extension arm and elevating gear; the first extension arm is fixedly connected with the lifting device, the second extension arm is fixedly connected with the drilling module, and the first extension arm is connected with the second extension arm through a bolt.

This scheme is a drilling and the geotechnical reconnaissance machines of surveying the integral type design, and among the specific structural design, the base of this machines is regarded as to the bottom plate, drilling part is used for surveying the system of boring with the monitoring hole, survey subassembly is used for monitoring of water level in its after the monitoring hole is accomplished.

In the concrete structural design, consider that current elevating gear all has the biggest stroke of certain numerical value, mostly be the vertical type application, drilling rod on the drilling module all has the maximum length of certain numerical value, mostly is the vertical type application, the design does the drilling module forms detachable connections relation through first extension arm and second extension arm and elevating gear, like this, to some if elevating gear reaches the biggest stroke or drilling rod is whole to go into underground after deeply, the hole depth of gained monitoring hole still can not be used for during ground water level monitoring, through removing being connected of first extension arm and second extension arm for elevating gear resets, adjusts the length of drilling rod or changes behind the longer drilling rod, can further right the monitoring hole further drills, finally obtains the monitoring hole that the degree of depth is suitable.

So this scheme of adoption is convenient for according to particular case, change or the length of adjustment drilling rod to make its different drilling depth of adaptation that can be better, reduce the limitation of this utensil application.

Meanwhile, as a person skilled in the art, the application of the present tool is not limited to the detection of the groundwater level, for example, the present tool can be used for detecting or monitoring other media, such as gas components, specific component gas concentrations, specific substances, specific substance concentrations, etc., by replacing different sensor types.
