In following explanationIn, the not necessarily same embodiment that different " embodiment " or " embodiment " refer to. In addition,Special characteristic, structure or feature in one or more embodiment can be combined by any suitable form.
As shown in Figure 1, a kind of mud sampling equipment that an embodiment of the present utility model proposes, itsComprise: cylindrical shell 1, upper cover 2, lower cover 3, shadoof 4 and pulling part 5, upper shed place of cylindrical shell 1Connect and have upwardly extending guide post 11, the top of guide post 11 is provided with block 111, cylindrical shell 1Inside there is coaxial pilot sleeve 12, pilot sleeve 12 is fixed in cylindrical shell by support; Upper cover2 edge has the pilot hole being slidably connected on guide post, and upper cover 2 can be by pilot hole in guidingOn bar 11, slide, to cover in the upper shed of cylindrical shell 1, or separate from the upper shed of cylindrical shell 1; CarryOne end of bar 4 is connected in lower cover 3, and the other end is successively through pilot sleeve 12 and upper cover 2; LiftPortion 5 comprises that the first pulling part 51 and 52, the first pulling parts 51, the second pulling part are connected with upper cover 2,The second pulling part 52 is connected with the other end of shadoof 4.
In use, sliding on the upwardly extending guide post that upper cover can connect in upper shed place of cylindrical shellMoving, shadoof one end connects lower cover, and the other end is successively through being arranged on inner barrel and coaxial the leading of cylindrical shellTo sleeve and upper cover, and the first pulling part in pulling part is connected with upper cover, the second pulling part withThe other end of shadoof connects. Concrete sampling operation is: first, detect according to the sounding instrument of drilling machineThe hole of fill orifice at the bottom of to the distance of the lower cover of mud sampling equipment of the present utility model, user's handling withThe second pulling part that shadoof connects, slowly transfers mud sampling equipment along the center of fill orifice, nowAs shown in Figure 2, the utility model mud sampling equipment is complete closed state, when mud sampling equipmentThe desired depth position of transferring to grout hole, stops transferring the second pulling part, lifts afterwards and top capThe first pulling part connecing, makes upper cover upward sliding on guide post, when the block of upper cover and guide post touchesTouch, the first pulling part is fixed to the first pulling part and second being now connected with upper cover and shadoof respectivelyPulling part is lifting mud sampling equipment simultaneously, continues to transfer the second pulling part, and lower cover is moved downwardThe distance of 100mm left and right, this action 3 to 5 times repeatedly, finally lifts the second pulling part by lower cover and cylinderBody fastens, and slowly promotes, and in the process promoting, upper cover and cylindrical shell fasten, by the mud envelope of samplingExist in bucket, promote mud sampling equipment to pouring into aperture, the mud of extraction is poured into pre-prepdIn vessel, can carry out next step detection to mud index.
Concrete, it is long generally at tens meters to 60 to 70 meter that the revolving of mud off scrapes out hole pouring pile stake,For ensureing quality and the bearing capacity of pile body, need to ensure that the sediment thickness index at the bottom of hole meets the demands, rootRequirement according in " technical code for building pile foundation ": before concrete perfusion, at the bottom of hole, 500mm is with interior mudSlurry relative density should be less than 1.25; Sand factor is not more than 8%; Viscosity is not more than 28s. So extractApart from the mud at 500mm place at the bottom of fill orifice, need the utility model mud sampling equipment to transfer toApart from the position at 500mm place at the bottom of fill orifice, now lower cover apart from fill orifice at the bottom of 500mm. To extractMud sample test, so mud does not meet code requirement, needs to change in fill orificeMud, and the mud after changing is sampled to detection, until the mud of sampling reaches " building pile foundationTechnical specification " in requirement, stop mud checking.
In technical solutions of the utility model, the global shape of mud sampling equipment is barrel shape, cylindrical shell upperOpening part is provided with upwardly extending guide post, and the upper cover of cylindrical shell can be slidably reciprocated on guide post,And there is block on the top of guide post, upper cover is in the time sliding into the top of guide post, and upper cover block keeps offFirmly can not continue upward sliding, realize upper cover covering and separating, the inside of cylindrical shell with respect to cylindrical shellBe provided with the pilot sleeve coaxial with cylindrical shell, and an one end is set is connected the other end with lower cover and wears successivelyCross the shadoof of pilot sleeve and upper cover, lower cover can be realized with respect to cylindrical shell under the control of shadoofCover and separate, in order to control the motion of the utility model mud sampling equipment in fill orifice, withAnd control upper cover and lower cover with respect to the covering and separating of cylindrical shell, be connected and carry respectively with on shadoof at upper coverDraw portion, under the control of pulling part, the utility model mud sampling equipment can be transferred to fill orificeDesired depth position, and control the folding with respect to cylindrical shell of upper cover and lower cover, and then needs are detectedMud running into tank, the sampling of taking out mud sampling equipment and complete mud from hole. Than existing skillIn art, there is no special mud sampling equipment, only can rule of thumb judge the thickness of sediment at the bottom of hole, useMud sampling equipment of the present utility model can extract the mud sample of the desired depth position of fill orifice,And then by the inspection to sampling mud, obtain the thickness data of sediment at the bottom of hole, check to obtain data beguineData according to micro-judgment are more reliable.
As shown in Figure 1, in the middle of concrete enforcement, wherein the first pulling part 51 comprises suspension ring 511, extremelyLack a rope 512 and the first lining rope 513 with length scale; First of rope 5112End is connected with upper cover 2, and the second end of rope 512 is connected with suspension ring 511, the first lining rope 513One end is connected with suspension ring 511, and the other end is for gripping; The second pulling part 52 is with length scaleThe second lining rope, one end of the second pulling part 52 is connected with shadoof 4, and the other end is for gripping.
Concrete, the rope of the first pulling part can be arranged to two, three or four, evenlyBeing connected to of distributing covers, and the other end of rope is all connected on suspension ring, like this by being connected toLining rope on suspension ring can be mentioned upper cover, and in the process promoting at upper cover, because upper cover is subject to evenly to divideThe pulling force of the rope of cloth, can deflection, straight up motion in upper cover ascending process. Because of firstPulling part and the second pulling part are all used the lining rope with length scale as lifting parts, thus underIn the process of side's the utility model mud sampling equipment, can know mud by the length scale on lining ropeThe distance that sampling equipment is transferred, realizes the sampling of the mud at 500mm place at the bottom of fill orifice hole of adjusting the distance.
Wherein lining rope can adopt the steel wire rope with length scale, or uses the Buddhist nun with length scaleLong Sheng, steel wire rope and nylon rope are high and cheap with respect to other materials intensity, can reduce this realityBy the cost of novel mud sampling equipment.
