According to sample requirement, the track that drill bit is advanced first is drawn, determines tilt angle.Selected drilling machine stand, Ying Bao
It is relatively flat solid to demonstrate,prove parking area, portable drilling rig is driven into parking place, it is solid to stretch out support frame towards drilling direction for mast
Determine drilling machine.Mast foot hydraulic support is adjusted, mast and level ground are formed into certain tilt angle, and mast is slided out to ground
Face.Starter is screwed on drilling rod, drilling rod is fixed on clamping device, and rear end is connected on Power Component.It starts
Motor rotation drilling rod promotes, and after a rod boring is to underground, connects next drilling rod, drilling rod is spirally connected step by step, drilling rod
It connects or separates and is realized by unloading buckle.Often into a bar, position and the depth of drill bit will be monitored in real time.
When needing to adjust drill bit direction of travel, the direction of starter is observed by monitor.Guide plate direction 12
It when o'clock direction, stops rotating, promotes drilling rod, then drilling rod is up advanced；Similarly, direction such as nine o'clock, three of guide plate are adjusted
The directions such as o'clock, six o'clock, can control drilling rod underground to left and right and lower direction advance.When depth bigger drill bit encounters resistance
When power can not promote, starts the force (forcing) pump on drilling machine, deionized water is injected into drill bit by the hollow duct of drilling rod, through on drill bit
Limbers outflow, promote drill bit drilling, mud outside drilling rod lateral edge drilling outflow ground.
When starter reaches sampling location, certain distance is slightly exited into drilling rod reverse rotation, starts water plug,
The mud in drilling is extracted out using drilling rod.Then pumpback drilling rod all proposes drilling rod.By the guiding on last root drilling rod
Drill bit is laid down, and soil sampler is changed to, and is then pushed into sampling location again, manipulates drilling machine, sampler is directly pushed away into soil layer,
Soil just enters in the hollow probe tube 22 of soil sample collector 20, then pumpback drilling rod, lays down soil sample collector 20, in taking-up
Empty probe tube 22.According to the usage amount of Soil K+adsorption, the both ends of hollow probe tube 22 are cut, with seal cap sealing, number is put
Enter sample storage case, completes soil sampling.
According to the drill bit travel track of setting, continues drilling to next sampling location and carry out sampling according to aforesaid operations.
Soil and groundwater sample can be disposably acquired at different location, different depth.
To prevent tilting drilling from may result in the pollutant migration and diffusion at different location, after the completion of sampling, then
Drilling rod is pushed into and is drilled, bentonite or cement slurry are injected by the hollow duct of drilling rod, when on one side extracting drilling rod by root out, on one side
Bentonite or cement slurry are gradually injected, until ground, completes to block.
In embodiment, drilling machine nest point will be used as at the outside 4.7m of three sampled point lines and landfill yard boundary intersection,
Portable drilling rig is driven into parking place, mast stretches out the fixed drilling machine of support frame towards sampled point.Adjust the hydraulic branch of mast foot
Mast and level ground are in 20 degree of inclination angles, and mast are slided out to ground by frame.Starter is screwed on drilling rod, by drilling rod
It is fixed on clamping device, rear end is connected on Power Component.The propulsion of motor rotation drilling rod is started, when a rod boring arrives
After underground, be spirally connected next drilling rod, often into a bar, will monitor position and the depth of drill bit in real time.Pass through drilling rod when drilling
Hollow channel injects deionized water to drill bit.When starter creeps into 26.3m, when reaching the first sampling location, i.e. underground water
At 9m, about 50cm distance is exited into drilling rod reverse rotation, starts water plug, is extracted out the mud in drilling using drilling rod.So
Pumpback drilling rod all removes drilling rod afterwards.Starter on last root drilling rod is laid down, is changed to soil sampler, then
It is pushed into sampling location again, manipulates drilling machine, sampler is directly pushed away to about 1m into soil layer, soil just enters in sampling pipe, then
Pumpback drilling rod lays down drilling rod to last root by root, sampling pipe is laid down, clip 30cm long, both ends seal cap sealing, compiled
Number, it is put into sample storage case, completes soil sampling.
The direction of starter is observed in the sampling for carrying out second point by monitor, by drill bit guide plate direction ten
Two o'clock direction, stop rotating, promote drilling rod, then drilling rod is up advanced, until adjusting drilling rod to being 3.8 with horizontal line angle
Degree；Stop promoting, rotary drill rod creeps into 15.03m, reaches the second sampled point, carries out soil and ground according to above-mentioned same method
It is lauched sampling.When completing second sampled point, up about 0.54 degree of guide plate direction is adjusted, precession promotes 35.06m to reach
Third sampled point, uses in the same way.
After the completion of sampling, then drilling rod is pushed into and is drilled, by the hollow injection bentonite of drilling rod or cement slurry, will bored on one side
When bar is extracted out by root, bentonite or cement slurry are gradually injected on one side, until ground, completes to block.
