The utility model is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Description of drawings
Fig. 1 is the structural representation of the utility model static sounding equipment;
Fig. 2 is the vertical view of Fig. 1 middle cross beam and drive unit;
The specific embodiment
As shown in Figure 1, be the structural representation of the utility model static sounding equipment.This static sounding equipment comprises the static sounding frame, the static sounding frame is provided with grade beam 7, two hydraulic jacks 3 on grade beam 7, installing, between the top of two hydraulic jacks 3, be fixedly connected with crossbeam 6, on crossbeam 6, be set with two columns that stretch out 4 downwards, between the end of two columns 4, be connected with and stablize beam 13, be provided with drive unit 2 above the crossbeam 6, drive unit 2 is a kind of hydraulic motor, hydraulic motor is provided with two oil pipes 51, and rotating disk 21 is the rotatable parts of hydraulic motor.Be provided with hexagonal through hole 11 (see figure 2)s at the center of rotating disk 21.Pillar assembly 1 comprises some joint pillars, increase length by increasing the pillar joint number, the bottom of wherein first joint pillar is provided with teeth 12, the top of pillar assembly removably connects by forming between pillar cap 8 and the hexagonal kelly 10, be provided with water inlet 9 on the top of hexagonal kelly 10, in hexagonal kelly 10 and pillar cap 8, be provided with water channel from water inlet 9 to the pillar assembly.The shape of the shape of cross section of hexagonal kelly 10 and hexagon through hole 11 is complementary.Six side's feeler levers 10 are inserted in the through hole 11, can freely slide up and down and can rotate and drive along with the rotation of rotating disk 21 pillar assembly 1 and rotate.
It is as follows to use the test method that above-mentioned static sounding equipment carries out static sounding: the static sounding machine is fixed on the cone penetration test place, and the oil circuit 5 of hydraulic jack 3 is connected with an oil pump; Feeler lever is inserted through hole 11 carry out cone penetration test first, the device drives that promptly turns on the power oil pump, making hydraulic jack 3 retractions drive crossbeam 6 moves down, thereby feeler lever is pressed in the soil, after hydraulic jack 3 retracts to extreme position, start oil pump again after the disconnection oil pump rises crossbeam 6 and make the hydraulic jack retraction in the feeler lever injection soil.And so forth and the joint number that increases feeler lever reaches between 20 to 30 meters of the desired depths of cone penetration test first up to the degree of depth of feeler lever till.Afterwards feeler lever is extracted and feeler lever is removed from the static sounding frame by joint.
After feeler lever is removed from the static sounding frame, hexagonal kelly 10 is inserted in the through hole 11 at rotating disk 21 centers, and at the lower end of hexagonal kelly 10 connection pillar cap 8, the head of pillar assembly 1 is saved pillar place the top of the formed test hole of cone penetration test first, pillar assembly 1 is connected with pillar cap 8, the oil pipe 51 of drive unit 2 is connected with the oil circuit of oil pump.Starting oil pump makes rotatable parts 21 rotate and drive six side's feeler levers 10 and 1 rotation of pillar assembly, pillar assembly 1 is drilled under self gravitation in the formed test hole of cone penetration test first, rotate in the process that pierces at pillar assembly 1, stablize beam 13 and can prevent that pillar from rocking and flexural deformation.In addition, in rotating process, also in the pillar assembly, import cooling water from the top water inlet 9 of hexagonal kelly 10 by water pump, cooling water cools off pillar and prevents that pillar is overheated, flow out in the gap that cooling water and the head by pillar assembly 1 save between pillar and the test hole soil wall, pillar is played lubricated effect, reduce the frictional force between the pillar and the soil body.When saving pillar, head soon do not bury fully when middle, suspend the rotation of rotating disk, increase the step of pillar joint number, promptly disconnect pillar cap 8 and save being connected of pillar with pillar assembly 1 head, promote hexagonal kelly 10 and pillar cap 8, to increase pillar newly is placed between first joint pillar and the pillar cap 8, with pillar cap 8 with after newly-increased pillar is connected, starting rotatable parts 21 continues pillar is drilled in the test hole, after this just do not connect newly-increased pillar in the time of in the minor details pillar will not soon bury at the top of minor details pillar, and pillar is drilled into last time cone penetration test and forms in the stationary contact test hole by joint, slightly shallower in depth is set till the degree of depth of test hole that last time cone penetration test forms up to pillar assembly 1.
After the degree of depth is set reaches this stage desired depth of pillar assembly 1 first, pillar cap 8 is disconnected and being connected, and remove hexagonal kelly 10 with hexagonal kelly 10, pillar assembly 1.After utilizing slush pump that the earth in the pillar is removed, put into feeler lever at the top of pillar assembly 1, carry out the cone penetration test second time.After the desired depth that arrives cone penetration test for the second time, take out feeler lever, increase pillar on pillar assembly 1 top that was provided with last time and carry out the pillar setting second time and subsequent cone penetration test for the third time again, so circulation reaches the experimental design degree of depth up to the feeler inspection total depth of feeler lever.
More than describe preferred embodiment of the present utility model in detail.The ordinary skill that should be appreciated that this area need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, in all technical fields the technician according in the design of the present utility model, prior art basis by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in claim protection domain of the present utility model.
