Description
Technical field
The present invention relates to a kind of cement grout sampler of triaxial cement mixing pile, particularly a kind of cement grout sampler that in foundation workss such as building, municipal administration, water conservancy, is used to check, study technical indicators such as triaxial cement mixing pile intensity, homogeneity.
Background technology
Domestic equipment and the technology of introducing the triaxial cement mixing pile machine of Japan from 1997 is used for the triaxial cement mixing pile construction that the shaped steel soil cement stirs wall, obtained in engineering widely and used.But the research of domestic intensity for triaxial cement mixing pile is quite not enough, and the cement mixing method method of inspection that adopts in the practice of construction has static sounding, standard injection, boring and coring and single pile load test etc. usually.But have all that the test result error is big, the sampling success ratio is low and the destructible engineering in the cement earth pile that uses or the weak point of wall.
For overcoming above-mentioned weak point, China utility model patent ZL 200620046546.1,2007.12.12 disclose a kind of cement and earth automatic sampler for mix base, its casing is the cylinder of up/down perforation, door is arranged on the wall, the inwall of casing is connected with support and casing support, one side inwall is connected with the push pedal groove, the top of pushing ram is connected with Powerpush Unit, pushing ram is respectively with last, following two connecting rods and leverage are hinged, and the fulcrum of connecting rod and leverage is fixed on the casing, terminal each link to each other with push pedal up and down, respectively there is a cover plate push pedal inboard, and push pedal is inserted up and down in the push pedal groove; Sampling maintenance jar is the cylinder of upper and lower perforation hereinafter to be referred as " sampling jar ", is positioned in the middle of the casing by the dull and stereotyped wing; Take out and put into by door.A plurality of casings can be connected in series or and connect with bolt by web joint and/or shaped steel.This sampling function is taken out the original standard cement and the earth blend sample of designated depth and position automatically by Ground Control 1～30 meter degree of depth.But this sampler is owing to adopt Electric Machine Control mode, complex structure, needs long cable to connect and is used in conjunction with large-scale hoisting machinery, particularly under big degree of depth situation, makes things convenient for inadequately during long cable operated.
Summary of the invention
The objective of the invention is to, a kind of cement grout sampler of triaxial cement mixing pile is provided, automatically obtain soil cement mixed serum before the original position initial set conveniently to be implemented in different depth, zones of different, neither destroy cement earth pile or wall, be convenient to later stage indoor intensity test operation again.
The present invention adopts following technical scheme:
A kind of cement grout sampler of triaxial cement mixing pile is characterized in that comprising: following rotation cover, connecting rod, sampling jar, last rotation cover, fork, fixed frame, interlock straight-bar, first traction rope, second traction rope; Described sampling jar is fixed on the described fixed frame; Described fork middle-end connects upward rotation cover, one end of described fork connects the upper end of interlock straight-bar, the lower end of interlock straight-bar is connected with an end of described connecting rod, and the other end of described connecting rod is connected with following rotation cover, and the two ends of described fork connect described first traction rope and second traction rope respectively.
Further, also comprise guide housing and following guide housing, described upward guide housing and following guide housing are separately fixed at the top and bottom of described fixed frame, and described sampling jar is fixed in described going up between guide housing and the following guide housing.
Further, the length range of described first traction rope and second traction rope is 0.5 to 30 meter.
The invention has the beneficial effects as follows: the present invention adopts the swing of fork to realize that by connecting rod and straight-bar rotation cover rotates up and down, opens or closes when reaching the sampling jar upper and lower opening.Realize on-the-spot original position initial water earth mixed serum sampling.Can satisfy the soil cement mixed serum of obtaining the original position original state in different depth, zones of different.The invention solves the key issue of on-the-spot original position initial water earth mixed serum sampling,, solved the difficult difficulty of depths cement grout sampling for the measurement of indexs such as the intensity of cement mixing method, homogeneity provides convenient and practical detection kit.

Embodiment
As shown in Figure 1, a kind of cement grout sampler of triaxial cement mixing pile comprises: following rotation cover 1, connecting rod 2, sampling jar 3, last rotation cover 4, fork 5, fixed frame 6, interlock straight-bar 7, last guide housing 8, following guide housing 9, first traction rope 10, second traction rope 11.
Wherein, last guide housing 8 and following guide housing 9 are separately fixed at the top and bottom of fixed frame 6, and sampling jar 3 is fixed in described going up between guide housing 8 and the following guide housing 9.
Described fork 5 middle-ends connect upward rotation cover 4, and an end of described fork 5 connects the upper end of interlock straight-bar 7, and the lower end of interlock straight-bar 7 is connected with connecting rod 2 one ends, and the other end of described connecting rod 2 is connected with following rotation cover 1.
Described fork 5 can reach the state of Long-distance Control fork 5 by first traction rope 10 and 11 pullings of second traction rope.Moving of described fork 5 makes that going up rotation cover 4 links, and makes described rotation cover 1 down also link by interlock straight-bar 7 and connecting rod 2 simultaneously, realizes opening or closing of sampling jar 3.
Before the sampling, make fork 5 be in horizontality, and strain second traction rope 11 earlier, thereby make sampling jar 3 in open mode.Send in the process of the degree of depth that needs sampling at sampling jar 3, because the cement grout acting in conjunction that the pulling force of second traction rope 11 gushes on reaching, sampling jar 3 is in the state of opening all the time, and constantly pours into cement grout.After arriving sampling depth, sampling jar 3 is promptly filled required cement grout automatically.Then, when first traction rope 10, under the effect of pulling force, fork 5 becomes plumbness, and fork 5 rotates upward rotation cover 4 rotations of drive, and rotates by rotation cover 1 under interlock straight-bar 7 and connecting rod 2 drives, realizes closing of sampling jar 3.
Further, the length range of described first traction rope 10 and second traction rope 11 is 0.5 to 30 meter.
Its crucial innovative point: in traction rope effect draft link 5 state variation, rotation cover 1 and last rotation cover 4 open or close simultaneously under driving, and realize the automatic folding of sampling cover, finish on-the-spot original position initial water earth mixed serum sampling.This mechanism in 30 meters of any degree of depth of soil cement building foundation, finishes the automatic sampling work of soil cement in conjunction with triaxial cement mixing pile mechanical energy.
