Abstract
The utility model discloses a pipe drainage type open double-wall soil sampler. The soil sampler comprises a solid liner tube (15), a hollow liner tube (11), a shoe (3), a connecting port (9), drainagechannels (6), a ball valve (5) and a fixed head (10), wherein the solid liner tube (15) constitutes a soil sample cavity (1); the hollow liner tube (11) constitutes a waste soil cavity (2); a drainage pipe (12) is arranged between a liner tube at the top of the waste soil cavity and the ball valve and communicated with the drainagechannels through the ball valve; a plurality of drainage holes (7) are formed in the inner wall (14) of the hollow liner tube, a corresponding quantity of water inlets (13) are also formed in the drainage pipe (12), and the drainage holes are communicated with the water inlets through thin drainage tubes (8). According to the soil sampler, waste water in the waste soil cavity can be drained to the maximum extent, the soil sampler is particularly applicable to limestonedistribution areas with abundantunderground water, and the soil sample quality can be greatly improved.
Description
technical field:
The utility model relates to a kind of soil sample barrel, and specifically a kind of Geotechnical Engineering is drilled the uncovered multiple wall soil sample barrel of a kind of row of conduits ability of swimming used that fetches earth.
background technology:
Along with developing rapidly of national economy, Geotechnical Engineering industry development makes rapid progress, and along with the continuous expansion of its scale, the problem relating to is also more and more, and the problem of the on-the-spot probing of Geotechnical Engineering soil sampling is exactly one of them important problem.Traditional scene is drilled the soil sample barrel adopting that fetches earth and is generally uncovered soil sample barrel, this kind of soil sample barrel generally contains bushing pipe, shoe, connector, drainage channel, ball valve and gland, in bushing pipe inwall, be provided with soil sample chamber and roach chamber, between roach top of chamber bushing pipe and ball valve, be provided with drainpipe, drainpipe is connected with drainage channel by ball valve, and described bushing pipe is a solid metal bushing pipe.This soil sample barrel is only applicable to fetch earth under the engineering geological condition of and moisture content less more closely knit at soil layer, and for the higher soil layer of water cut, limestone as more rich in underground water Distribution Area, in the process of fetching earth, the waste water that soil sample enters after soil sample barrel is difficult to effectively be discharged, if waste water cannot be discharged in time and is easily back to soil sample chamber, cause the disturbance greatly of undisturbed soil.The drainage problem of soil sample always is the problem that has a strong impact on undisturbed soil and be difficult to be resolved.Therefore, invent a kind of uncovered soil sample barrel that can effectively get rid of waste water and there is very important practical significance.
summary of the invention:
the purpose of this utility model aims to provide the uncovered multiple wall soil sample barrel of a kind of improved uncovered soil sample barrel-row of conduits ability of swimming, the defect existing to overcome prior art, thus effectively guarantee the original state of soil sample.
For realizing above-mentioned purpose of the present utility model, the technical scheme adopting is: the uncovered multiple wall soil sample barrel of a kind of row of conduits ability of swimming, contain bushing pipe, shoe, connector, drainage channel, ball valve and gland, in bushing pipe inwall, be provided with soil sample chamber and roach chamber, between roach top of chamber bushing pipe and ball valve, be provided with drainpipe, drainpipe is connected with drainage channel by ball valve, its design feature is: described bushing pipe contains solid bushing pipe and hollow bushing pipe two parts, the bushing pipe that forms soil sample chamber is solid bushing pipe, the bushing pipe that forms roach chamber is hollow bushing pipe, on the inwall of hollow bushing pipe, be provided with several osculums, on drainpipe, be also provided with several inlet openings of respective amount, osculum is connected by draining tubule with inlet opening.
Using method of the present utility model is: in the time that headway per drill bit reaches the soil layer that need to sample, this soil sample barrel is changed, drilled the standard operation of fetching earth.Enter the moisture content in roach chamber, a part directly enters drainage channel from drainpipe and is discharged from, another part enters drainpipe by the osculum on bushing pipe inwall through draining tubule and discharges, draining is more abundant, because the waste water in soil sample is effectively got rid of, therefore can subtract in real time intratubular hydraulic pressure, make soil sample be not affected or less affected by disturbance, can farthest guarantee the original state of soil sample, reach the fetch earth requirement of original state of engineering.The utility model is particularly useful for the more rich limestone of underground water Distribution Area, can greatly improve soil sampling quality.
Accompanying drawing explanation
Fig. 1 is the vertical section structure schematic diagram of the utility model embodiment.
Fig. 2 is the annexation figure of draining tubule and bushing pipe inwall and drainpipe.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to further detailed description.
From Fig. 1 and Fig. 2, can find out, the utility model contains bushing pipe 4, shoe 3, connector 9, drainage channel 6, ball valve 5 and gland 10, in bushing pipe inwall, be provided with soil sample chamber 1 and roach chamber 2, between roach chamber 2 top bushing pipes and ball valve 5, be provided with drainpipe 12, drainpipe 12 is connected with drainage channel 6 by ball valve 5, described bushing pipe 4 contains solid bushing pipe and hollow bushing pipe two parts, the bushing pipe that forms soil sample chamber 1 is solid bushing pipe 15, the bushing pipe that forms roach chamber 2 is hollow bushing pipe 11, on the inwall 14 of hollow bushing pipe 11, be provided with several osculums 7, on drainpipe 12, be also provided with several inlet openings 13 of respective amount, osculum 7 is connected by draining tubule 8 with inlet opening 13.
As can be seen from Figure 1, shoe 3 is positioned at soil sample barrel front end, and as the mouth of pipe that fetches earth of soil sample barrel, its cross section is wedge shape, and bottom surface is sharper, for soil sample barrel incision soil; Bushing pipe 4 is positioned at shoe 3 tops, the soil sample chamber 1 in careful bushing pipe 15, and for depositing undisturbed soil, roach chamber 2 is positioned at the top in soil sample chamber 1, is connected with soil sample chamber 1; Osculum 7 is positioned on the inwall 14 of 2 middle parts, roach chamber hollow bushing pipe 11 on the upper side, is connected, and then is connected with drainage channel 6 by ball valve 5 by draining tubule 8 with drainpipe 12; Described connector 9 is positioned in gland 10, and for being fixedly connected with drilling rod, the lower end of gland 10 is connected with bushing pipe 4.
