Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
As Figure 1-4, mark 1-20 in figure to be respectively: drill pipe sub 1, osculum 2, rotating dog 3, inner core 4, water intaking water feed apparatus 5, inlet opening 6, plug-in and pull-off device 7, nothing revolution water column table 8, water pressure gauge sensor 9, inlet opening 10, filter screen 11, drill bit changing-over screw thread 12, forced drill bit 13, urceolus 14, pointer back to zero reset button 15, Water collecting tube 16, the cover 17 that catchments, back-up ring 18, water inlet treatment hole 19, rotary bit 20.
Embodiment: as shown in Figure 1, the pressure-bearing device for fetching water from the present embodiment comprises inner core 4, urceolus 14, piecing devices and drill bit.Inner core 4 and urceolus 14 surface offer inlet opening respectively, and urceolus 14 is sleeved on the periphery of inner core 4, freely can rotate between the two and make the inlet opening contraposition on inside and outside cylinder surface form the formation partition that is communicated with or misplaces, carry out into water to regulate inlet opening when reaching the sampling depth of piestic water, inlet opening to be just communicated with, and inlet opening dislocation partition carries out sealing before reaching sampling depth.
Inner core 4 includes filter screen 11, water intaking water feed apparatus 5, water pressure gauge device and drill bit changing-over screw thread 12.Filter screen 11 is sleeved on inner core 4 periphery and between inner core 4 and urceolus 14, is mainly used in carrying out physical filtering for the water entered, and ensures the quality of water intaking.Water inlet water fetching device 5 adds into the quantity of water aperture 6, plug-in and pull-off device 7 and Water collecting tube 16, wherein Water collecting tube 16 is arranged on the inside of inner core 4, and plug-in and pull-off device 7 is for the ease of being taken out from inner core 4 by Water collecting tube 16, the speed of water intaking and the convenience of water intaking effectively can be improved.Water pressure gauge device comprises without revolution water column table 8 and water pressure gauge sensor 9, is mainly used in the size of hydraulic pressure and the display of pointer in test current depth, is provided with pointer back to zero reset button 15 simultaneously, and this button is used for reset back to zero without revolution water column table 8.Be provided with drill bit changing-over screw thread 12 in the bottom of inner core 4, drill bit can be connected to tackle piercing of the adverse condition of various native stone, such as, forced drill bit 13 shown in Fig. 1 or rotary bit as shown in Figure 2 20.
Urceolus 14 top end surface is fixedly installed two pieces of back-up rings 18, as shown in Figure 3.Rotation sheath 3 on back-up ring 18 and joint is with the use of, effective contraposition water inlet and the dislocation sealing controlling the inlet opening on inside and outside cylinder surface.Rotating dog 3 is connected between two back-up rings 18.When drill pipe sub 1 driven rotary pin 3 rotates, rotating dog 3 drives back-up ring 18 to rotate, and now urceolus 14 produces relative to inner core 4 and rotates, and just can contraposition connection carry out blocking water into water or dislocation partition in the inlet opening on inside and outside cylinder.Urceolus 14 surface offers into water treatment hole 19, and this water inlet treatment hole 19 filters for carrying out first time to the water in native rock layers, and filter screen 11 filters for carrying out second time to water.
Piecing devices comprise rotation sheath 3, drill pipe sub 1 and osculum 2, wherein rotate sheath 3 and coordinate the back-up ring 18 of urceolus 14 to use; Drill pipe sub 1, for carrying out water intaking easy to connect with drilling rod, in order to make drill pipe sub 1 rotate by driven rotary pin 3, being fixedly connected with between the two and being integrally formed; Osculum 2 is opened in the connecting portion between drill pipe sub 1 and rotating dog 3, to prevent the excessive destruction to instrument of water pressure in drilling rod, when namely in drilling rod, water pressure is excessive, to discharge water the water pressure also reduced in drilling rod by opening osculum 2.
As depicted in figs. 1 and 2, drill bit is divided into two kinds, and one is forced drill bit 13, and another kind is rotary bit 20, is respectively used to carry out operation to weak and strong native stone.
In order to enable the piestic water sample in the Water collecting tube 16 of taking-up effectively be preserved, the cover 17 that catchments can be set, catchment between cover 17 with Water collecting tube 16 and forming detachable being fixedly connected with.When technician will catchment cover 17 be placed on Water collecting tube 16 time, effective sealing preservation can be carried out to the piestic water sample in Water collecting tube 16.
The present embodiment, when concrete operations, need coordinate drilling rod and rig to sample, have following concrete steps:
1) according to the specification of engineering characteristic and engineering construction institute foundation, the drilling rod of rig is connected with piecing devices 1.
2) urceolus 14 of sampler is rotated counterclockwise puts in place, the inlet opening dislocation on inside and outside cylinder surface is cut off, just carries out into water between the sampling depth reaching piestic water to prevent sampler.
3) drilling rod is lengthened, the piestic water sampling depth of specifying can be entered to make sampler entirety.
4) utilize drilling rig power plant, by sampler entirety press-in or rotary drilling to appointment native rock layers in, stop when entering completely in native rock layers creeping into.Utilize the drilling rod of rig to be turned clockwise by the urceolus 14 of sampler to put in place, make the inlet opening contraposition on inside and outside cylinder surface be communicated with the sampling carrying out piestic water.
5) after judging that piestic water has been full of Water collecting tube 16 according to the reading without revolution water column table 8 and water pressure gauge sensor 9, continue to utilize the drilling rod of rig to turn clockwise to put in place, the inlet opening on inside and outside cylinder surface is misplaced again and cuts off the intrusion of top water body when preventing from carrying brill.Afterwards, immediately ground is proposed to sampler.
6) by drill bit changing-over screw thread 12, drill bit is taken apart from inner core 4 bottom, Water collecting tube 16 is taken out from inner core 4, add water collector lid 17, add adhesive plaster and seal up, get final product sample presentation.
Although elaborate the design of the utility model object and embodiment with reference to accompanying drawing with above-described embodiment, but those of ordinary skill in the art can recognize, under the precondition not departing from claim limited range, still various improvement and conversion can be made to the utility model, as: change inner core 4 and the concrete shape of urceolus 14, the setting position with the parts of filtering function and structure etc., therefore do not repeat one by one at this.
