Description
Technical field
The present invention relates to a kind of mud sampler, particularly a kind of drilling pouring pile hole bottom slurry sampler and calculating thereof, sampling method.
Background technology
" technical code for building pile foundation " requires: before the concrete perfusion, 500mm should be less than 1.25 with interior mud relative density at the bottom of the hole; Sand content must not be greater than 8%; Viscosity must not be greater than 28s.Difficulty is all felt by domestic construction pile foundation construction unit when implementing, carrying out this clause content.
How 500mm sampling at the bottom of the hole does not have method, does not have ready-made instrument.So just issue and implement a period of time in standard, many units in charge of construction all seek help to the supervising engineer at scene.When checking and accepting this clause content generally speaking, with management and the following processing of Party A building site masterpiece: the mud circulation pump is opened, allow mud circulation in the hole, determine the mud circulation time in the hole according to aperture, hole depth, generally be 15--20min, under the situation that does not stop mud circulation, get mobile mud in the aperture and measure then, think that the mud in aperture this moment is approaching or the same substantially with the situation at the bottom of the hole.Even the reality cyclic process, the mud density at the bottom of the hole, sand factor, viscosity and aperture also variant; The mud on ground is static at the bottom of the preceding hole of concrete spouting in addition, and the suspended state of mud particle, the performance of mud and cyclic process are widely different.
Summary of the invention
Deficiency in view of prior art exists the invention provides a kind of drilling pouring pile hole bottom slurry sampler.
The present invention for achieving the above object, the technical scheme of being taked is: a kind of drilling pouring pile hole bottom slurry sampler is characterized in that; Comprise base, limited post, guide peg, sample bucket, carry ear, guide collar, drop handle, sealing ring, seal cover, fixed limit post on the described base, two described guide peg one ends and base are fixed, the other end passes four guide collar and the seal cover that are fixed on the sample bucket outside respectively and fixes, described sealing ring is bonded on the end face of seal cover, two described carry ear respectively symmetry be fixed on the sample bucket lateral surface, two described drop handles respectively with carry ear and flexibly connect.
Drilling pouring pile hole bottom slurry sampler calculates, sampling method, it is characterized in that: described calculating, sampling method step are as follows: step 1,1., at first set mud balance scope in institute's gaging hole;
2., determine sample bucket deadweight, its design formulas is: G=ρ gV promptly: G is that sample bucket weight=ρ is that sample bucket density g is the volume of sample bucket steel pipe for acceleration of gravity v;
3., determine sample bucket suffered maximum buoyancy in the hole; Its design formulas is: F=ρ gV promptly: F is that sample bucket suffered maximum buoyancy=ρ in the hole is the volume of sample bucket for acceleration of gravity v for mud density g;
4., comparative result; G＞F;
5., slurry sampler can operate as normal;
Orderly being wrapped on the special-purpose turntable of lifting lining rope of step 2, slurry sampler that assembling is connected is positioned over aperture to be measured to turntable, and sampler is vertically slowly put into the hole, the lining rope that at the uniform velocity veers away, and the 2m place will slowly transfer at the bottom of the distance hole;
After step 3, sampler arrive at the bottom of the hole, suitably discharging 80mm～100mm lining rope, sample bucket can continue to sink to separating with seal cover, seal cover is opened, and mud enters sample bucket;
The sample of step 5, taking-up carries out analyzing and testing on request.
The invention has the beneficial effects as follows: the sampler principle is simple and clear, and is easy to make, can gather materials on the spot, with low cost, and handling safety, and using method is simple, and is respond well.Can be applicable to hole depth and be no more than mud sampling in the holing with slurry wall protection castinplace pile in 100 meters any apertures.
Description of drawings
Fig. 1 is for structural representation of the present invention and as Figure of abstract.
The specific embodiment
As shown in Figure 1, drilling pouring pile hole bottom slurry sampler comprises base 1, limited post 2, guide peg 3, sample bucket 4, carries ear 5, guide collar 6, drop handle 7, sealing ring 8, seal cover 9.
At first at an end threading of two guide pegs 3; Symmetry is bored saturating two holes on the face of circular seal lid 9; On seal cover 9 other ends, paste sealing ring 8; Radially weld four guide collar 6 in sample bucket 4 outside symmetries; Carry ear 5 in 6 two vertical of the radial symmetric welding of sample bucket 4 and guide collar; At cup dolly 1 circle centre position welded limiting post 2.
Two guide peg 3 one ends and base 1 welding are fixing, the other end (end of band screw thread) passes four guide collar 6 that are fixed on sample bucket 4 outsides respectively, its sample bucket 4 and two guide pegs 3 are slidingly matched, be screwed into respectively on the screw thread of two guide pegs 3 with two nuts 10, seal cover 9 in the one side that will be pasted with close circle 8 is gone on the guide peg 3 by two borehole jacks on its face, with two nuts 10 seal cover 9 is fixed on the guide peg 3, the end that two drop handles, 7 band circles are colluded colludes two respectively and proposes flexible connection in the ear 5 at last again.
Sampling method:
To promote that lining rope one end and two drop handle 7 one ends hitch or hitch two and carry behind the ear 5 again and promote lining rope one end and fasten and connect with one section lining rope, orderly being wrapped on the special-purpose turntable of the lining rope other end will be promoted, turntable is positioned over aperture to be measured, sampler is vertically slowly put into the hole lining rope that at the uniform velocity veers away, and sampler 2m place at the bottom of the distance hole will slowly transfer.After sampler arrives at the bottom of the hole, suitably discharging 80mm～100mm lining rope, it is that seal cover 9 is opened that its sample bucket 4 can continue to sink to separating with seal cover 9, and mud enters sample bucket 4; Sampler leaves standstill at the bottom of the hole and can at the uniform velocity promote in 10～15 seconds, and sampler will slowly promote at 2m place, distance aperture; Sampler is left standstill on the platform, lay down the nut on the seal cover 9, with seal cover 9 remove mud weight indicator can be put into that sample bucket 4 is measured or with sample bucket 4 by extracting out on the lead 3, pour mud in the tube into mud balance, funnel viscometer, sand content apparatus etc. and carry out proportion, viscosity, sand factor and measure.
The sampler computational methods:
Suppose in institute's gaging hole the mud balance scope between 1.05～1.5, under the situation of our computation of mud sampler, the suffered buoyancy maximum of sample bucket, can sampler operate as normal:
Sample bucket deadweight G=ρ g.V; ρ: sample bucket density 7.8 * 10
3Kg/m
3G:9.8N/Kg v: the volume of sample bucket steel pipe; V=π D.h. δ (π=3.14, D=50mm, h=300mm, δ=3mm)
Like this: G=7.8 * 10
3Kg/m
3* 9.8N/Kg * 3.14 * 50 * 10
-3M * 300 * 10
-3M * 3 * 10
-3M=10.8N;
Sample bucket is suffered maximum buoyancy F=ρ g.V ρ in the hole: mud density 1.5 * 10
3Kg/m
3G:9.8N/Kgv: the volume v=π of sample bucket. (D
2/ 4) .h (π=3.14, D=50mm, h=300mm);
Like this: F=1.5 * 10
3Kg/m
3* 9.8N/Kg * 3.14 * [(50 * 10
-3M)
2/ 4] * 30 * 10
-2M=8.65N;
Comparative result: 10.8N＞8.65N is promptly: G＞F;
So: slurry sampler can operate as normal.
