Abstract
The utility model discloses a static sounding device, which employs a geological driller 1, a drill rod 2 and a drill head 3 and realizes water circulation by employing a drill water pump for reducing frictional resistance in the time of penetrating into underground. A force conversion device 4 is arranged between the drill head 3 and a static sounding electric probe 5, which realizes the rotation of the drill rod 2 and the drill head 3, and the static sounding electric probe does not rotate. The projected area of a conical tip of the static sounding electric probe is shortened below 10 square centimeters for reducing the end portion resistance in the time of penetration. The utility model has the advantages of large depth of penetration, convenience and low costs of the static sounding device.
Description
Technical field
The utility model relates to a kind of static sounding equipment that is used for builing industry engineering exploration and in-situ test.
Background technology
At present, static sounding equipment with steel feeler lever and static sounding electrical measurement probe, is pressed into the mechanical property of test soil the soil layer by static pressure from ground.Because feeler lever and probe are subjected to the very big penetration resistance of soil layer, comprise side friction resistance and end resistance, static sounding equipment depth of penetration is less.
Summary of the invention
The purpose of this utility model provides the bigger static sounding equipment of a kind of depth of penetration.
The purpose of this utility model is achieved through the following technical solutions.
The utility model static sounding equipment adopts geological drilling rig to make the drilling rod rotation, drilling rod drives drill bit rotary cutting soil layer, and realize the water circulation casting with the rig water pump, to reduce the frictional resistance of drilling rod side when the underground injection, static sounding electrical measurement probe is installed in the drill bit, a power conversion device is housed therebetween, the rotation of realization drill bit, and static sounding electrical measurement probe does not rotate, static sounding electrical measurement probe only bears static pressure, end resistance when reducing injection narrows down to the sharp projected area of static sounding electrical measurement probe awl below 10 square centimeters, thereby realizes strengthening the purpose of depth of penetration.
The advantage that the utlity model has is: the depth of penetration of static sounding equipment is big, light, cost is low.
Below in conjunction with drawings and Examples the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model static sounding equipment.
The specific embodiment
Show as Fig. 1, the geological drilling rig 1 that the utility model adopts, should select power unit type light 100 type hydraulic drill rigs for use, drilling rod 2 is a steel standard geologic drilling rod, drill bit 3 and power conversion device 4 can be customized to mine detecting set factory, static sounding electrical measurement probe 5 and ground receiving instrument 6, existing homemade and patent of introduction product can be for selecting for use or the customization of size on request, and the sharp projected area of static sounding electrical measurement probe 5 awls is preferably 1 square centimeter.
The utility model adopts conventional drilling technology to execute brill, and injection speed satisfies the requirement of static sounding national standard.1 pair of drilling rod 2 of geological drilling rig and drill bit 3 are implemented static pressure and rotation combining ability, make drilling rod 2 and drill bit 3 rotations, make static sounding electrical measurement probe 5 only be subjected to vertical static pressure by power conversion device 4, static sounding electrical measurement probe 5 is pressed in the soil layer, the data of the static sounding electrical measurement probe 5 soil layer resistances that changed are stored in memory or are transmitted into ground receiving instrument 6 after being gathered by static sounding electrical measurement probe 5, thereby realize the static sounding test in the drilling process.
Claims (3)
1. static sounding equipment, comprise rig (1), drilling rod (2), drill bit (3), power conversion device (4), static sounding electrical measurement probe (5), ground receiving instrument (6), it is characterized in that: between drill bit (3) and the static sounding electrical measurement probe (5) power conversion device (4) is installed.
2. static sounding equipment according to claim 1 is characterized in that: power conversion device (4) is the steel thrust bearing structure.
3. static sounding equipment according to claim 1 is characterized in that: the sharp projected area of static sounding electrical measurement probe (5) awl is less than 10 square centimeters.
