Abstract
The utility model relates to a slurry sampler for sampling slurry at the construction site of soil cement piles and soil cement walls and can overcome shortcomings that sample has no representative caused by that the conventional sampler is possible to be mixed soil cement slurry in non-target positions during sampling. The slurry sampler in the utility model sinks a sample bucket into soil cement piles and soil cement walls from the ground by means of connecting drill pipes with the same length one by one and controls the sampling depth position accurately. Mandrels are arranged in the drill pipes and can rotate freely. Length of mandrels is equal to length of the drill pipes. The drill pipes and the mandrels are connected with the sample bucket and the mandrels are rotated on the ground by a handle to drive an open-and-close screw in the sample bucket for opening and closing a top cover of the sample bucket, thereby obtaining soil cement slurry sample. The sampler is in a seal state in the process of sinking and lifting, thereby realizing the purpose of accurately obtaining real sample.
Description
1 technical field
The utility model relates to cement earth pile, the employed a kind of slurries sampler of slurries sample is got at the wall scene.
2 background technologies
Cement-soil is the original position soil body and cement, through stirring into slurries, after a kind of firming body that solidify to form, the firming body physico-mechanical properties is relevant with different depth soil body self property according to a certain percentage for water.Cement earth pile, wall quality inspection method have: original position is got slurry preparation test block method, original position core boring sampling law and in situ test method.Existing related specifications (" shaped steel cement-soil stir wall technology rules " JGJ/T 199-2010) suggestion adopts original position to get slurry method, and clearly propose " sample point should be arranged in the above 1m scope in the foundation ditch end, hole with the agitation pile of cheating soft layer place at the end in." so the cement grout sampler to adapt to this demand, can guarantee accurately to obtain at cement earth pile, within the walls designated depth place slurries becomes the key that original position is got slurry method.At present, mostly the sampler that uses in the industry is logical heart bucket formula sampler, that is, sampler transfers to the target location and cuts out cover plate up and down with breakthrough status up and down, cement grout is promoted to the face of land accomplishes sampling.Possibly be mixed with non-target location cement grout in the sample that logical heart bucket formula sampler deficiency is to obtain; Cause the main cause of this situation to be: sampler sinks in the cement grout process with breakthrough status up and down; Like slurry consistency sticking the staying on the sampler sidewall of mud on the sinking path must be arranged more greatly; Even local soil block stops up the sampler of up/down perforation fully; Be mixed with non-target location mud in the sample that causes obtaining or all be non-target location mud, final result is that the sample that extracts can not be represented the target location truth.
To sum up; Need a kind of sampler,, can guarantee not have slurries and infiltrate by being air-tight state before the surface subsidence arrival sampling target location; Can open after arriving the target location; Slurries can be closed after being full of sampler, are promoted to the face of land with air-tight state, thereby realize accurately obtaining the purpose of target depth position authentic sample.
3 summary of the invention
In order to satisfy above requirement; The utility model provides a kind of cement grout sampler; This sampler can accurately be obtained the cement grout of target depth position, and is in sealing state in sampler sinking and lifting process, can not sneak into non-target depth cement grout.
The utility model solves the technical scheme that its technical problem adopted: through the mandrel (3) in handle (1) rotary drill rod (2); Mandrel is connected with inserting mode with mandrel interface (5) on opening and closing screw rod (9); Drilling rod (2) links to each other with top cover (6) through drilling rod interface (4); Sealed bearing (7) is housed on the top cover (6), links to each other with sample bucket (12) through opening and closing screw rod (9), and can tightly combine; Shang Lianliang (10), Di Lianliang (13) are arranged in the sample bucket (12), open and close screw rod (9), prevent revolving pin-and-hole (8), bottom (14) is fixed on the sample bucket (12) by set bolt (15).
Be provided with mandrel in the sampler drilling rod, mandrel can rotate freely, and rotates mandrel through handle on ground, and " the switching screw rod " in the transmission sample bucket opens and closes the sampler top cover.
The beneficial effect of the utility model is, the depth selection position is accurate, can not sneak into non-target location cement grout in the original position slurries sample of collection, and sample is true and reliable, and is representative, can reliable basis be provided for workmanship and design.

5 specific embodiment
Among Fig. 1, handle (1) links to each other with mandrel (3) as the Power Drive Unit of opening, close sampler on the ground.Mandrel (3) places in the drilling rod (2), and is concentric with drilling rod (2), can rotate freely.Drilling rod (2) is threaded io the drilling rod interface (4) on the top cover (6) by ground by joint, connects with inserting mode efficiently between mandrel.Bottom mandrel (3) is connected with inserting mode with the mandrel interface (5) on main switching device " switching screw rod " (9) top of sampler.Mandrel interface (5) is nested in the drilling rod interface (4), and drilling rod interface (4) rotates freely relatively.Switching screw rod (9) passes sealed bearing (7) and is installed on the top cover (6), can freely rotate relative to top cover (6).The anti-pin (8) that revolves is equipped with in top cover (6) bottom, and inserts anti-the revolving in the pin-and-hole (11) to prevent that top cover (6) is with opening and closing screw rod (9) rotation on the sample bucket.Be provided with twice in the sample bucket (12) and connect beam, be respectively the Shang Lianliang (10) and the end and connect beam (13), there is screw at two Lian Liang centers; Open and close screw rod (9) and be screwed in Shang Lianliang (10) screw, thereby connect loam cake (6) and sample bucket (12).Bottom (14) connects beam (13) through the set bolt (15) and the end and is connected, thus sealing sample bucket bottom.
Sampler uses step following:
1. at first bottom (14) is installed on the sample bucket (12), tightens set bolt (15) and reach seal request;
2. use handle (1) to insert mandrel interface (5), rotary handle (1) transmission opens and closes screw rod (9), and top cover (6) is closed, and does sampling and prepares;
3. a cover drilling rod (2), mandrel (3) are linked to each other with drilling rod interface (4), mandrel interface (5), increase drilling rod, mandrel, sampler is sunk down into target depth selection position by joint;
4. handle (1) is plugged on the mandrel (3), rotary handle (1), transmission opens and closes screw rod (9), opens sampler top cover (6), leaves standstill a moment, treats that cement grout is full of sample bucket (12);
5. reverse rotation handle (1), transmission opens and closes screw rod (9), closes sample bucket top cover (6);
6. the lifting sampler is removed drilling rod (2) and mandrel (3) by joint;
7. after sample bucket is promoted to ground, outside mud flush is clean, turn on set bolt (15), open bottom (14), pour cement grout in the sample bucket into die trial, make test block.
8. sampling finishes, and sampler is rinsed well connector position oiling maintenance.
