Abstract
The utility model relates to a rotary static contact survey probe which can seal water injection channel. The rotary static contact survey probe is composed by connecting an overtopped probing rod joint, an abrasion reducer, a transition joint, a storage rod and a probe body in turn, wherein the water supply channel of the overtopped probing rod joint is provided with an one-way valve which can be switched into water supply state; the valve core of the one-way valve is composed of a valve plate, a valve rod fixed on the valve plate and a return spring; the valve plate is jointed with the shoulder of the water supply channel of the joint; the upper surface of the valve plate is provided with a plunger jointed with the water supply channel of the joint in sealing type; the periphery of the valve plate is distributed with overtopped grooves; the valve rod is jointed with a support seat of the joint water supply channel in sliding type; and the support seat is distributed with overtopped holes. The one-way valve of the probe can baffle underground water from entering into the water outlet of the abrasion reducer to avoid reverse ejection, when ground water supplier stops or the one-way valve is normally closed when the pressure is lower than the underground water, thereby avoiding muddiness of operation fields to avoid affecting operation, and preventing the water supply holes from being blocked by sand or foreign materials, to support stable operation of the device.
Description
Technical field
The utility model belongs to sounding device, particularly relates to the rotary type static sounding probe of the sealed waterflood path of engineering geologic investigation.
Background technology
Static sounding is to adopt the injection pressure of power source that the feeler inspection probe is pressed into a kind of engineer geological prospecting method that soil layer is implemented in-situ test.
A kind of rotary type static sounding probe is connected to form successively by mistake water probing rod joint, friction reducing device, transit joint, storage-pole and probe body, and friction reducing device is provided with the center that is connected with mistake water probing rod joint water channel and crosses water sidewalk for visually impaired people and weep hole thereof.Transit joint is constituted by rotary part and on-rotatably moving part, makes storage-pole and probe body only bear power source injection pressure.Storage-pole is to be provided with the storage device that the analog quantity that the probe body sensors is exported is converted to digital quantity and real-time storage or is forwarded to ground receiving equipment.The probe body is single bridge probe or doube bridge probe.
Above-mentioned rotary type static sounding probe can obviously improve the accuracy of depth of penetration and feeler inspection data.But experiment finds, when out of service or pressure reduced when the ground of sounding device water supply facilities, feedwater often appearred in the above-mentioned feeler lever that offers aquaporin or underground water is regurgitated phenomenon.Underground water is regurgitated and is not only caused operation field muddy and influence operation, the more important thing is occur easily sneaking into the sand grains regurgitated in the water or foreign material disabling facility to the water hole.
Summary of the invention
The utility model is to provide a kind of rotary type static sounding probe that seals waterflood path in order to solve the technical problem that feedwater that above-mentioned rotary type static sounding probe exists or underground water regurgitates phenomenon.
The utility model is taked following technical scheme for achieving the above object: this rotary type static sounding probe is by crossing the water probing rod joint, friction reducing device, transit joint, storage-pole with the probe body be connected successively form, it is characterized in that: cross giving of water probing rod joint and be one way valve when being provided with conducting in the aquaporin to water state, the spool of described one way valve is by valve plate, the valve rod that is fixed in the valve plate basal surface constitutes with the back-moving spring that is set in valve rod, valve plate with encircled the water probing rod joint and engage for the shoulder of aquaporin, the valve plate upper surface is provided with and crosses the plunger that water probing rod joint feedwater channel seal engages, the valve plate circumferential distribution had the water groove, the bearing slip joint that valve rod and mistake water probing rod joint are provided with to aquaporin, bearing is distributed with water hole, is provided with the valve plate back-moving spring that is set in valve rod between valve plate and the bearing.
The utility model can also be taked following technical measures:
The plunger of described one way valve is provided with O-ring seal.
The beneficial effects of the utility model and advantage are: the one way valve of crossing the setting of water probing rod joint of this rotary type static sounding probe; when out of service or pressure is lower than groundwater pressure at the ground of sounding device water supply facilities is normally off; effectively water resistance ends feedwater or underground water and enters from the delivery port of friction reducing device and form reverse regurgitating; thereby can avoid the operation field mire and influence operation, that also can avoid sand grains or foreign material disabling facility simultaneously helps equipment stable operation to the water hole.The utlity model has simple in structure, stop feedwater or underground water to regurgitate the outstanding advantage of obvious results.
