Abstract
The invention relates to a method and equipment for arranging a static penetration protection pipe of a deep hole static cone penetration test in shallow soil. The static penetration protection pipe is pressed in the soil by utilizing the power of a static cone penetration machine, therefore, a slip for clamping the protection pipe is arranged at the lower part of the upright shaft of the static cone penetration machine; the protection pipe is downwardly pressed by utilizing the self power of the static cone penetration machine so that the protection pipe is sent into the soil; in the deep hole static cone penetration test, a drilling machine is not utilized to arrange the protection pipe any longer; one set of equipment can be prevented from being conveyed to a construction field; two sets of equipment are unnecessary to be used alternately any longer; the construction efficiency is greatly increased; and the cost is saved.
Description
Technical field
The present invention relates to the deep hole cone penetration test, particularly relate to a kind of method and apparatus that the quiet spy pillar of deep hole cone penetration test is set at the soil layer superficial part.
Background technology
Cone penetration test is at the uniform velocity to be pressed into the taper shape probe with certain specification in the soil by machinery, to measure the isoparametric a kind of home position testing method of probe resistance.
In deep hole cone penetration test penetration process, tend to take place feeler lever deflection even disconnected bar phenomenon.This mainly is owing to be prone to take place deflection along with depth of penetration increases probe; If press down and meet pan soil in the process, then penetration resistance increases, and feeler lever bends, and finally causes disconnected bar.Superficial part is provided with quiet spy pillar in the cone penetration test hole, is one of main method that solves by feeler lever deflection and disconnected bar, promptly in superficial part certain depth scope, sends into quiet spy pillar, and pillar plays guide effect on the one hand, prevents deflection; Limit the degree of crook of feeler lever in the pillar on the other hand, prevent the feeler lever fracture, thereby play protective effect feeler lever.
The quiet spy pillar of Set For Current is to accomplish through drilling equipment, like this, in implementation process, needs the construction of marching into the arena of another set of drilling equipment.Practical implementation step: earlier carry out upper soil horizon and test, generally to the 30m, then quiet spy machine is withdrawn from quiet spy machine; With rig the proof soil layer in top is removed, transferred pillar, rig is withdrawn from then; With quiet spy machine replaced, carry out the test of following soil layer again.This method need be marched into the arena by two complete equipments, and will be used alternatingly, time-consuming like this effort again, inefficiency.
It is thus clear that how the quiet spy pillar of superficial part being sent in the soil layer quickly and efficiently is the key of dealing with problems.
Summary of the invention
Technical problem to be solved by this invention is exactly to provide a kind of for the defective that overcomes above-mentioned prior art existence at the soil layer superficial part method and apparatus of the quiet spy pillar of deep hole cone penetration test to be set, thereby raises the efficiency, practices thrift cost.
The object of the invention can be realized through following technical scheme: at the soil layer superficial part method of the quiet spy pillar of deep hole cone penetration test is set, may further comprise the steps:
1) in the vertical shaft bottom of static sounding machine slips is set;
2) quiet spy pillar is passed slips;
3) vertical shaft of lifting static sounding machine;
4) with slips quiet spy pillar is blocked;
5) press down the vertical shaft of static sounding machine.
Among other embodiment of the present invention, can also may further comprise the steps:
6) slips unclamps quiet spy pillar;
7) vertical shaft of lifting static sounding machine;
8) with slips quiet spy pillar is blocked;
9) press down the vertical shaft of static sounding machine;
10) repeating step 6)～step 9), so that quiet spy pillar is pressed in the soil layer of desired depth.
Described static sounding machine adopts fluid pressure type static sounding machine.
Described static sounding machine promotes and presses down vertical shaft through its hydraulic power mechanism.
The present invention also provides a kind of equipment that the quiet spy pillar of deep hole cone penetration test is set at the soil layer superficial part; It is characterized in that; Comprise static sounding machine and the slips that is used to block quiet spy pillar; Described static sounding facility have the actuating unit that is used for to soil layer injection probe, and described actuating unit has the vertical shaft that transmission is used, and described slips is located at the bottom of vertical shaft.
Described static sounding machine adopts fluid pressure type static sounding machine or mechanical type static sounding machine.
Compared with prior art; The present invention utilizes the hydraulic power of static sounding machine, and quiet spy pillar is pressed in the soil layer, no longer utilizes rig to carry out the pillar setting; Can transport a set of equipment less to the job site; Also no longer need being used alternatingly of two complete equipments, improved efficiency of construction greatly, practiced thrift cost.
Description of drawings
Fig. 1 is the sketch map of one embodiment of the present of invention.
Wherein: the quiet spy pillar of 1-, 2-oil cylinder, 3-slips, 4-vertical shaft, 5-oil circuit, 6-crossbeam, 7-grade beam.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
Of the present inventionly method one specific embodiment of the quiet spy pillar of deep hole cone penetration test is set, may further comprise the steps at the soil layer superficial part:
1) in the vertical shaft bottom of static sounding machine slips is set;
2) quiet spy pillar is passed slips;
3) vertical shaft of lifting static sounding machine;
4) with slips quiet spy pillar is blocked;
5) press down the vertical shaft of static sounding machine.
When quiet spy pillar was failed to be pressed in the soil layer of desired depth, the present invention can also may further comprise the steps:
6) slips unclamps quiet spy pillar;
7) vertical shaft of lifting static sounding machine;
8) with slips quiet spy pillar is blocked;
9) press down the vertical shaft of static sounding machine;
10) repeating step 6)～step 9), so that quiet spy pillar is pressed in the soil layer of desired depth.
The present invention also provides a kind of equipment that the quiet spy pillar of deep hole cone penetration test is set at the soil layer superficial part; Comprise static sounding machine and the slips that is used to block quiet spy pillar; Described static sounding facility have the actuating unit that is used for to soil layer injection probe; Described actuating unit has the vertical shaft that transmission is used, and described slips is located at the bottom of vertical shaft.
Described static sounding machine adopts fluid pressure type static sounding machine or mechanical type static sounding machine.
Preferably, present embodiment adopts fluid pressure type static sounding machine, promotes and presses down vertical shaft through its hydraulic power mechanism, and as shown in Figure 1, the detailed process of present embodiment is following:
If do not reach the predetermined degree of depth; Can make slips unclamp quiet spy pillar, promote static sounding machine vertical shaft, press down vertical shaft once more after with slips quiet spy pillar being blocked to certain altitude; But like this repeated multiple times, in the soil layer that quiet spy pillar is pressed into desired depth till.
